Bethi CMS, Prakash GJ, Pedda MS, Kudre TG. Utilization of lactobacillus fermented proteins from meat processing wastewaters as a dietary protein source in poultry feed. 3 Biotech 2023; 13:69. [PMID: 36733382 PMCID: PMC9886724 DOI: 10.1007/s13205-023-03487-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/26/2022] [Accepted: 01/20/2023] [Indexed: 01/31/2023] Open
Abstract
The present study aimed to evaluate the impact of fermented meat processing wastewater protein hydrolysate (FWMPH) prepared by Pediococcus lolii fermentation as an alternative protein source on growth performance, serum biochemistry, and hematological parameters of broiler chicks. FWMPH exhibited antioxidant, anti-angiotensin converting enzyme (ACE), and antimicrobial properties. A total of 60 one-day-old Vencobb broiler chicks were divided into five dietary groups on day 8 and a feeding trial was performed for 48 days. Diets were prepared by replacing soya protein concentrate (SPC) at different levels of FWMPH as the protein source. These diets were denoted as SPSD (100% SPC), FMP-25 (25% FWMPH + 75% SPC), FMP-50 (50% FWMPH + 50% SPC), FMP-75 (75% FWMPH + 25% SPC), and FMP-100 (100% FWMPH). FMP-25 and FMP-100 diet group broiler chicks showed the highest and lowest feed consumption (P < 0.05), respectively. However, the highest body weight gain (1506.08 ± 52.52 g) was observed in FMP-75 diet-fed chicks (P < 0.05). Furthermore, FMP-75 chicks displayed better feed conversion ratio (1.96), feed efficiency ratio (0.51), and protein efficiency ratio (2.32) values than other diet group chicks (P < 0.05), implying that the FMP-75 diet had better effect on the broiler growth. Also, the FMP-75 diet chicks showed better hematological values, serum biochemical parameters revealed no negative effect upon FWMPH consumption, and no pathological signs were observed in the histopathological examination as compared to the SPSD diet group (P < 0.05). Hence, the results could be helpful in the application of FWMPH at 75% level in the poultry feed as a potential protein ingredient in the countries looking for local feed protein products as soya bean meal replacement.

Abstract
Abstract
The study determined the effect of introducing 50% of protein from the protein feed pool derived from raw chickpea seeds instead of 50% of soybean meal in the rearing period from day 22 to 42 on the coefficients of nutrient digestibility, growth performance, selected carcass traits, the hematological and metabolic profile of blood, and the quality of femur bones in male Ross 308 broilers. The study was carried out on 200 22-day-old male Ross 308 broiler chicks (initial weight of 756 g) randomly assigned to two groups (n=100 in each group; 5 cages with 20 birds each). All birds were reared for 42 days. They were fed isonitrogenous and isoenergetic pre-experimental starter diet (day 1 to 21) in the crumble form and experimental grower-finisher diets (day 22 to 42) in the pelleted form. From rearing day 22, SBM male broilers (grower/finisher) were fed diets with 100% SBM as a protein source. In the diet for the CPR group (grower and finisher), the SBM protein was replaced with 50% of CPR-derived protein. During the grower and finisher stage and between days 22 and 42, the CPR group exhibited significant (P=0.032) reductions in feed intake (FI), higher (P=0.043) slaughter yields, high (P=0.044) % share of breast muscles, and reduced (P=0.003) abdominal fat content. The addition of CPR influenced some blood parameters. The level of total protein, urea, and Mg decreased, whereas the activity of alkaline phosphatase (ALP) and aspartate transaminase (ALT) increased. In the CPR group, an increase in the physical, morphometric, and some strength parameters of the femur (maximum elastic strength – Wy, yielding deformation – dy, bone density index – BDI, and Young’s modulus) was observed. Therefore, CPR may be a promising partial substitute of SBM in broiler nutrition, as it enhances production performance and has a beneficial effect on bone quality.

The effect of the dietary inclusion of pea seeds of colored-flowered and white-flowered varieties on gastrointestinal function in turkeys. ANIMAL NUTRITION 2022; 10:167-177. [PMID: 35785251 PMCID: PMC9207289 DOI: 10.1016/j.aninu.2022.03.007] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 09/06/2021] [Revised: 01/25/2022] [Accepted: 03/15/2022] [Indexed: 12/04/2022]
Abstract
This study investigated the effects of dietary replacement of soybean meal (SBM) with graded levels of pea seeds (PS) on the gastrointestinal function of turkeys. Seeds of 2 pea varieties, a colored-flowered variety and a white-flowered variety (CFP and WFP, respectively) were fed to 56-d-old birds for 8 wk. A total of 539 female Hybrid turkeys were allocated to 7 groups, each group consisted of 7 pens with 11 birds per pen. The experiment had a 2-factorial design, with 3 dietary inclusion levels of PS (100, 200 and 300 g/kg) and 2 pea varieties (CFP and WFP). The control group (diets without PS) was compared with CFP and WFP treatments by simple contrast analysis. In comparison with CFP seeds, WFP seeds contained 7-fold less tannins (0.67 vs. 4.66 g/kg) and less non-starch polysaccharides (NSP, 117.8 vs. 132.7 g/kg), but more trypsin inhibitors (1.34 vs. 0.98 g/kg) and starch (489 vs. 455 g/kg). A rise in the PS content of diets from 100 to 200 and 300 g/kg increased the weight of the small intestine (P = 0.031) and the dry matter (DM) content of intestinal digesta (P = 0.001), but it had no effect on the pH of digesta. Only the highest PS content differentiated the concentrations of short-chain fatty acids (SCFAs) in the small intestinal digesta (WFP > CFP, P = 0.008), whereas PS did not cause any changes in the morphological parameters of the small intestinal mucosa. The dietary inclusion of PS had no influence on the levels of acetate, butyrate, putrefactive SCFAs or total SCFAs in the cecal contents. Apart from increasing the activities of β-glucosidase (P = 0.017) and β-galactosidase (P = 0.025), pea varieties did not affect the activities of the analyzed cecal microbial enzymes. However, CFP seeds decreased the DM content (P = 0.041) and increased the pH of cecal digesta, compared with WFP seeds (P = 0.013). The results of this study, pointing to a few differences in the functional parameters of the small intestine and cecum, indicate that tannins are not a factor differentiating the suitability of CFP and WFP seeds in the nutrition of finisher turkeys. The inclusion of PS at 200 and 300 g/kg of the diet reduces the content of SBM and wheat in turkey diets, which has a positive effect on gastrointestinal function.

Raw Chickpea ( Cicer arietinum L.) as a Substitute of Soybean Meal in Compound Feed for Broiler Chickens: Effects on Growth Performance, Lipid Metabolism, Fatty Acid Profile, Antioxidant Status, and Dietary Value of Muscles. Animals (Basel) 2021; 11:ani11123367. [PMID: 34944144 PMCID: PMC8698175 DOI: 10.3390/ani11123367] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/27/2021] [Revised: 11/19/2021] [Accepted: 11/23/2021] [Indexed: 11/29/2022] Open
Abstract
Simple Summary Defatted soybean meal is the basic source of protein in poultry diet. Therefore, researchers are searching for an alternative source of vegetable protein derived from native raw materials. The present results were obtained in an experiment consisting in the use of soybean meal in the diet for broiler chickens, or the replacement of 50% of soybean meal protein with raw chickpea seed protein. The impact of the substitution on the poultry production process and on the dietary value of poultry meat was assessed. Abstract The aim of this study was to determine the effect of substitution of 50% of soybean meal protein with 310–350 g/kg diet of raw chickpea seed protein on the chemical composition, fatty acid profile, dietary value, and antioxidant status of breast and thigh muscles, as well as the antioxidant status of blood serum, in Ross 308 male broilers. In the 42-day experiment, one-day-old male broiler chicks were assigned to two nutritional groups (n = 100 in each, 20 birds in each group, and 5 replications). In the control group, 100% of protein in the feed was derived from soybean meal. In the experimental group, 310–350 g/kg protein from raw chickpea seeds was introduced. Data with a normal distribution were analyzed using the Student t-test, and the relationships between the traits were assessed with the use of Pearson’s correlation coefficients. p < 0.05 was considered statistically significant. The replacement with chickpea protein did not exert an impact on the final body weight, feed consumption, and feed conversion ratio compared to the control group. However, it induced changes in the color of the breast muscles (increased L* and b* values), and reduced the cholesterol content. The addition of chickpea seeds improved the fatty acid profile, mainly in the breast muscle. A decrease in the total SFA content and a higher level of unsaturated fatty acids (UFA), UFAs/saturated fatty acids (SFAs), polyunsaturated fatty acids (PUFAs), omega-3, and omega-6 were observed in the experimental group. Additionally, the chickpea-supplemented group exhibited better values of meat quality indicators (atherogenic index-AI; thrombogenic index–TI, ratio of saturated fatty acids to unsaturated fatty acids-S/P, n-6/n-3, hypocholesterolemic/Hypercholesterolemic ratio-h/H). It can be concluded that raw chickpea seeds are a good source of protein in broiler chicken nutrition, and can replace the traditionally used protein source (soybean meal), simultaneously exerting a positive effect on the dietary value of poultry meat and an expected enhancing impact on consumer health.

The effect of supplementation with β-hydroxy-β-methylbutyric acid (HMB) to pregnant sows on the mucosal structure, immunolocalization of intestinal barrier proteins, VIP and leptin in the large intestine in their offspring. ANNALS OF ANIMAL SCIENCE 2021.

Abstract
Abstract
The large intestine epithelium plays an important role in water absorption and participates in fluid, acid-base and electrolyte balance, and the removal of waste products. The large intestine is rich in microorganism-presented enzyme activity. Apart from energy supply, the colon also participates in the synthesis of trophic factors and the modulation of the immune system and the systemic inflammatory response. The current study investigated the effects of dietary HMB administration to pregnant sows on the postnatal development of the colon in their offspring, at weaning. From the 70th to the 90th day of gestation, sows received either a basal diet (n = 12) or the basal diet supplemented with HMB (n = 12) at a dose of 0.2 g/kg of body weight/day. Maternal HMB treatment increased serum IgG and glucose concentrations and decreased serum urea concentration in the piglets. Basal histomorphometric analysis of offspring large intestines showed that prenatal HMB treatment led to a reduction in the thickness of the mucosa, submucosa and both types of myenterons, as well as reduced crypt thickness. The immunoreaction performed to mark T0 lymphocytes and total T lymphocytes in the colon wall showed that prenatal HMB treatment decreased the number of both types of lymphocytes. Greater expression for cadherin was found in the colon of piglets delivered by the HMB-treated sows. The expression of both tight junction proteins (occludin and claudin-3), as well as that of leptin, was stronger in the HMB-treated group. Vasoactive intestinal peptide (VIP) expression was stronger in the submucosal plexuses in the HMB maternal treated piglets, while no changes were observed in the myenteric plexuses. The results obtained indicate that the administration of HMB to pregnant sows significantly influenced the expression of leptin, VIP and some proteins of the intestinal barrier in their offspring, with less influence on large intestine basal morphology.

Abstract
Background and Aim: Tannins are functional secondary metabolites that may provide benefits to ruminants. However, to date, their effects on broiler chickens remain inconclusive. This study aimed to evaluate the effectiveness of dietary tannin levels on the performance, body organs, and amino acid (AA) digestibility of broiler chickens using a meta-analysis. Materials and Methods: After verification and evaluation, a total of 22 articles were included in the present study. All data regarding dietary tannin dosages, performance, digestibility, and gastrointestinal physiology of broiler chickens were tabulated into a database. The database data were then statistically analyzed using mixed models, with tannin dose as a fixed effect and study as a random effect. Results: High levels of dietary tannins negatively affected the average daily gain and average daily feed intake of broiler chickens according to linear patterns (p<0.001). In addition, dietary tannins decreased drumstick and liver weights, as well as bursa of Fabricius and spleen weight (p<0.05). Meanwhile, other carcass traits (i.e., thigh, wings, and body fat) were not influenced by dietary tannins. Regarding AA digestibility, high dietary tannin concentrations induced negative responses on isoleucine, leucine, and methionine digestibility (p<0.05). Conclusion: Dietary tannins appear to have a negative effect on broiler performance, lymphoid organ weight, and AA ileal digestibility. Hence, the addition of tannins to broiler diets is not recommended.

Changes in the Intestinal Histomorphometry, the Expression of Intestinal Tight Junction Proteins, and the Bone Structure and Liver of Pre-Laying Hens Following Oral Administration of Fumonisins for 21 Days. Toxins (Basel) 2021; 13:toxins13060375. [PMID: 34070555 PMCID: PMC8229214 DOI: 10.3390/toxins13060375] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/31/2021] [Revised: 05/20/2021] [Accepted: 05/21/2021] [Indexed: 01/12/2023] Open
Abstract
Fumonisins (FB) are metabolites found in cereal grains (including maize), crop products, and pelleted feed. There is a dearth of information concerning the effects of FB intoxication on the intestinal histomorphometry, the expression of intestinal tight junction proteins, and the bone structure and liver in pre-laying hens. The current experiment was carried out on hens from the 11th to the 14th week of age. The hens were orally administered an extract containing fumonisin B1 (FB1) and fumonisin B2 (FB2) at doses of 0.0 mg/kg b.w. (body weight), 1.0 mg/kg b.w., 4.0 mg/kg b.w., and 10.9 mg/kg b.w. for 21 days. Following FB intoxication, the epithelial integrity of the duodenum and jejunum was disrupted, and dose-dependent degenerative changes were observed in liver. An increased content of immature collagen was observed in the bone tissue of FB-intoxicated birds, indicating intensified bone turnover. A similar effect was observed with regards to the articular cartilage, where enhanced fibrillogenesis was observed mainly in the group of birds that received the FB extract at a dose of 10.9 mg/kg b.w. In conclusion, FB intoxication resulted in negative structural changes in the bone tissue of the hens, which could result in worsened bone mechanics and an increase in the risk of bone fractures. Fumonisin administration, even at a dose of 1.0 mg/kg b.w., can lead to degradation of the intestinal barrier and predispose hens to intestinal disturbances later in life.

Animals (Basel) 2020; 10:E1429. [PMID: 32824171 PMCID: PMC7459877 DOI: 10.3390/ani10081429] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/18/2020] [Revised: 08/13/2020] [Accepted: 08/13/2020] [Indexed: 01/22/2023] Open
Abstract
The purpose of this study was to determine the effect of dietary supplementation with coarse or extruded oat hulls on growth performance, blood biochemistry, cecal microbiota, and short chain fatty acids (SCFA) in broiler chickens. Chickens were randomly allotted to four dietary treatments consisting of a corn-wheat-soybean meal-based diet (Basal), Basal + Bacitracin methylenedisalicylate (BMD), Basal +3% coarse OH (COH), and basal +3% extruded OH (EOH). Feed intake (FI), body weight gain (BWG), and feed conversion ratio (FCR) were recorded weekly. On day 36, eight chickens/treatment were euthanized, blood samples were collected, and organ weights were determined. Cecal digesta samples were collected for the determination of SCFA concentration and microbial DNA sequence. Data were subjected to ANOVA using the mixed procedure of SAS. Alpha diversity was estimated with the Shannon index, and the significance of diversity differences was tested with ANOVA. Birds fed COH and EOH had reduced (p < 0.05) BWG, but there was no effect of treatment on FCR. There was a significant increase (p = 0.0050) in relative gizzard empty weight among birds that were fed COH, compared to the other treatments. Dietary treatments had no effect on blood biochemical parameters and SCFA concentration. Cecal microbial composition of chickens was mostly comprised of Firmicutes and Tenericutes. Seven OTUs that were differentially abundant among treatments were identified. In conclusion, supplementation of broiler chickens' diets with 3% COH or EOH did not affect the FCR, blood biochemical parameters and SCFA concentration, but modified few cecal microbiota at the species level. Dietary supplementation with COH but not EOH significantly increased the relative gizzard weight.

Abstract
Simple Summary The current study investigates the growth performance and bone status of grower–finisher pigs supplemented with phytase, an enzyme which increases the bioavailability of phosphorus in animal feeds. The study results provide new information with regards to the positive role phytase supplementation to livestock feed plays in the achievement of the maximum effectiveness of the feed, as well as numerous positive effects on bone characteristics (geometry, mineralization, and mechanical strength) in grower–finisher pigs. Abstract The objective of the current study is to assess the effects of the inclusion of 6-n phytase to a phosphorous-deficient diet on the growth performance (feed intake, average daily gain, and feed conversion ratio), apparent digestibility of calcium and phosphorus, and bone characteristics of grower–finisher pigs. The experimental diets included a phosphorus-deficient diet containing 0 (negative control), 250, 500, 1000, or 1500 FTU/kg of 6-phytase, and a diet formulated to meet the phosphorus nutrient requirements of pigs (positive control). Pigs were fed the experimental diets from the time they were ~35 kg body weight until they reached slaughter weight of ~110 kg. Bone status of the metacarpal (ash, mineral content) and femur (mineralization, geometry, and mechanical strength) bones were assessed. There was no effect of dietary treatment on feed intake. Feed conversion ratio was improved following inclusion of phytase at a dose of 500 FTU/kg or higher. Phytase inclusion at a dose of 1000 FTU/kg increased the average daily weight gain of grower–finisher pigs. Phytase inclusion at a dose of 500 FTU/kg was sufficient to increase metacarpal phosphorus content. Femur mid-diaphysis ash percentage was significantly increased even after the inclusion of the lowest dose of phytase. Analysis of structural parameters of femur mechanical strength (Young’s modulus, yield stress, yield strain, ultimate stress, ultimate strain) showed that the inclusion of a phytase dose of 500 FTU/kg in growing/finishing diets was sufficient to significantly improve bone status of grower–finisher pigs at slaughter.

Simple Summary In the poultry industry, where the cost of feed constitutes most of the expenses, sudden changes in feed prices make it a challenge for nutritionists to maintain the yield and health of animals while managing the diet costs. It is the first solution that comes to mind to use inexpensive raw materials while preparing diets in practical conditions. In addition, feeds used in diets should be digestible by poultry. In the poultry digestive system, feeds such as sunflower meals are difficult to digest due to containing high cellulose because there is no cellulase secretion in the digestive system. The use of multi-enzyme which enhanced the digestibility of nutrients and decreased antinutritional compounds such as cellulose and nonstarch polysaccharides in diets with sunflower meal can positively affect performance and the profitability of the growers. Abstract This study aimed to investigate the effect of dietary sunflower meal (SFM) and multi-enzyme levels on performance, carcass traits, intestinal histomorphology and pancreatic enzyme production in quails. Three hundred and twenty, 1-day-old quail chicks were divided into 8 groups with 4 replicates consisting of 10 birds each in the group. The experiment was randomized design consisting of a 4 × 2 factorial arrangement, with four levels of SFM (0%, 10%, 15%, or 20%) and two levels of multi-enzyme (0.0 or 1.0 g/kg) inclusion in the diet. The body weight, body weight gain, and feed conversion ratio were negatively influenced by the 15% and 20% SFM (p < 0.01) but were not affected by the 10% SFM for 6 week age. The relative gizzard (p < 0.05) weights significantly increased with 20% SFM, but the relative breast weight decreased (p < 0.01). The relative liver weight increased by the addition of enzymes in the diet (p < 0.05). The villus width (p < 0.01) and villus surface area (p < 0.05) of ileum increased linearly with SFM, whereas the villus height (p < 0.01), villus height: crypt depth (p < 0.01) and tunica muscularis thickness (p < 0.01) decreased linearly with SFM. Consequently, it is possible to say that the birds with the least absorptive same weight are the most efficient. The addition of multi-enzyme increased villus height and crypt depth but decreased tunica muscularis thickness of ileum (p < 0.01). Chymotrypsin activity in the pancreas decreased linearly with SFM (p < 0.01). Amylase activity in the pancreas decreased significantly with the addition of the multi-enzyme (p < 0.05). As a result of the study, SFM can be used at a 10% level in growing quail diets with beneficial effects on the absorption surface area. The effects of enzyme supplementation on parameters measured were less pronounced than the SFM inclusion level that higher villus height and lower tunica muscularis thickness were determined in multi-enzyme-fed birds compared to those untreated counterparts.

[PMID: 32210341 PMCID: PMC7093522 DOI: 10.1038/s41598-020-62282-7] [Citation(s) in RCA: 9] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/27/2019] [Accepted: 03/11/2020] [Indexed: 02/03/2023] Open
Abstract
The aim of the study was to evaluate the effect of feed containing faba bean on the physicochemical properties of breast and leg muscles. The study was conducted on 340 Ross 308 broiler chickens reared for 6 weeks. The control group received feed based on soybean meal. The treatment group received a feed mixture with faba bean as the source of protein. Different sources of protein in the diet were also associated with changes in the content of n-6 fatty acids (C16:0, C22:4) and the n-6/n-3 ratio in breast muscles, which was higher (P < 0.05) in treatment group. The collagen content was higher (P < 0.05) in breast muscles from control group. The study revealed that the use of faba bean as a substitute for soybean meal had no significant effect (P > 0.05) on water holding capacity, drip loss, or major chemical components of breast and leg muscles. The P/S ratio, AI and TI, and the content of cholesterol in breast muscles were comparable (P > 0.05) in both groups. The values of lightness (L*) for leg muscles were lower (P < 0.05) in treatment group. The use of faba bean instead to soybean meal in diets for broiler chickens had positive effects on meat quality traits.

Effect of Soybean Meal Substitution by Raw Chickpea Seeds on Thermal Properties and Fatty Acid Composition of Subcutaneous Fat Tissue of Broiler Chickens. Animals (Basel) 2020; 10:ani10030533. [PMID: 32235785 PMCID: PMC7143113 DOI: 10.3390/ani10030533] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/25/2020] [Revised: 03/12/2020] [Accepted: 03/17/2020] [Indexed: 12/13/2022] Open
Abstract
Simple Summary A soybean meal, commonly used as a primary source of protein in animal diets, is often obtained from processing genetically modified soybean varieties. The tendency to reduce the use of feeds containing transgenic constituents increases the need for alternative sources of dietary protein. In this study, we fed broiler chickens diets containing either soybean meal or raw chickpea seeds. We examined the effect of such a substitution on broilers’ subcutaneous fat tissue, which has numerous important physiological functions in chickens. Abstract In this study, the effect of soybean meal substitution by raw chickpea seeds on the thermal properties and fatty acid profile of subcutaneous fat tissue of broiler chickens was examined. The experiment, performed on Ross 308 chickens, lasted for 42 days. Tight subcutaneous fat tissue was analyzed using differential scanning calorimetry (DSC) measurements while the fatty acid composition of subcutaneous adipose tissue was determined chromatographically. There was no effect of soybean meal substitution on fat crystallization temperature or crystallization enthalpy. However, the total calorimetric enthalpy of the melting of low-melting monounsaturated and saturated triacylglycerols differed between groups. Fatty acid proportions in the subcutaneous fat tissue of broiler chickens were also altered. Among others, chickpea seed inclusion decreased the content of main saturated acid (palmitic acid) and increased the content of main monounsaturated (oleic) and tri-unsaturated (linolenic) acids. The results show that the soybean meal substitution by raw chickpea seeds in the feed can affect the structural properties of adipose tissue in broiler chickens, including the thermal transformation of unsaturated fatty acids. Due to the numerous physiological functions of subcutaneous fat tissue, understanding these mechanisms can promote the use of alternative protein both in poultry and human nutrition.

Abstract
Simple Summary The gastrointestinal tract; as an important mediator of nutrients and elements; regulates bone health. In this study, we examined the effect of supplementation with yeast Saccharomyces cerevisiae on bone characteristics in young Japanese quails. We found that yeast probiotics, through their action on the gut-bone axis, have a positive effect on the structure of articular cartilage and microarchitecture of trabecular bone in young female quails. These data could provide useful information for further research into the supplementation with yeast probiotics aimed to reduce the risk bone fractures during the egg-laying period Abstract The aim of the study was to investigate the changes in bone geometry, histological structure, and selected mechanical characteristics in young male and female Japanese quails supplemented with Saccharomyces cerevisiae. Quails were fed a basal diet containing no yeast or a basal diet supplemented with 1.5% (15 g per 1 kg of diet) of inactive S. cerevisiae, for a period of 42 days. S. cerevisiae inclusion had no effect on bone weight, length, and density, diaphysis geometry (cross-sectional area, wall thickness, moment of inertia) or on the mechanical strength (yield load, ultimate load, stiffness, Young’s modulus, yield stress, ultimate stress). Yeast supplementation improved the morphology of the articular cartilage both in male and female quails, as the total thickness of the articular cartilage was significantly increased. In trabecular bone, an increase in real bone volume and trabecular thickness was observed in females supplemented with S. cerevisiae, while in males the increase in trabecular number was accompanied by a reduction in trabecular thickness. The results of the present study demonstrate that S. cerevisiae, through a sex-dependent action on the gut-bone axis, improved the structure of articular cartilage and microarchitecture of trabecular bone. The positive effects of S. cerevisiae supplementation were more evident in female quails.

Abstract
This study focused on analyzing the effects of inclusion of modern hybrid rye to corn-wheat diet on mechanical properties of bones and tendons. A total of 224 broiler chickens were fed a diet without rye inclusion or a diet containing 15% of hybrid rye cv. Brasetto. The diets were either unsupplemented or supplemented with xylanase (minimum activity 1000 FXU/g, dose 200 mg/kg of feed). Each dietary group consisted of 56 birds. On day 42, selected chickens (n = 7 from each group) were slaughtered. Tibia were analyzed for mineralization, geometry, and biomechanical characteristics of bone mid-diaphysis. The mechanical properties of digital flexor III tendon were also assessed. Bone mineral density and bone ash percentage did not differ when both diets were given without xylanase. Enzyme supplementation increased bone mineral density (P < 0.01) in both dietary groups, whereas bone ash percentage (P < 0.01) increased only for corn-wheat diet. Rye inclusion had no effect on bone mid-shaft geometrical traits related to tibia weight-bearing capacity (cross-sectional area, cortical index, and mean relative wall thickness). Performed bending test showed no effect of hybrid rye inclusion on bone mechanical endurance. When xylanase was supplemented, bone length (P < 0.01) and weight (P < 0.05) decreased, whereas yield load (P < 0.01), stiffness (P < 0.05), Young modulus (P < 0.05), elastics stress (P < 0.01), and ultimate stress (P < 0.01) increased, irrespective of rye presence. The tendon tensile strain test showed that in corn-wheat diet enzyme supplementation positively influenced rupture force (P < 0.05) and tendon stiffness (P < 0.01). Xylanase supplementation increased the value of energy required to tendon rupture, irrespective of rye inclusion (P < 0.05). Study showed that modern hybrid rye varieties can be introduced to corn-wheat diets of broiler chickens in the aspect of animal welfare related to the development and homeostasis of musculoskeletal system, irrespective of xylanase supplementation. The enzyme addition positively affected biomechanical properties of bones and tendons.

Abstract
Abstract
The purpose of this paper was to assess the suitability of various protein feeds in broiler chicken feeding. The study covered 160 birds split into 5 equipotent groups (SBM, EFFS, RFFS, EL, DDGS). Four protein feeds were an experimental factor: extruded full-fat soybean (EFFS group), raw full-fat soybean (RFFS group), extruded lupine (EL group) and distillers dried grains with solubles (DDGS group) that were added to starter rations in an amount replacing 30%, and in grower and finisher rations 50% of extracted soybean meal protein. Results showed that after replacing an identical amount of extracted soybean meal protein with protein from extruded soybean or DDGS in chicken rations, the final body weight and feed conversion ratio were similar to those of birds from the control group. Deterioration (P≤0.01) in the above-mentioned parameters was observed for chickens fed with rations containing raw soybean or extruded lupine. Birds that were given rations containing raw soybean (RFFS group) were characterized by the lowest dressing percentage, and, compared to the control group, the difference was significant (P≤0.01). The type of protein feed contained in the rations did not affect the musculature of chickens, however it did impact their fat deposition. Fat deposition was the lowest in birds from RFFS and DDGS groups that reached the lowest final body weight. Microscopic images of all examined livers showed a normal histological structure. The results of the studies carried out provide a basis for recommending the use of extruded full-fat soybean or DDGS in broiler chicken rations as partial substitutes for extracted soybean meal protein.

Abstract
Bone volumes and quality are related to their hormone levels in laying hens. In this study, we investigated letrozole (LZ) induced effects on the physicochemical properties of cortical bone in laying hens. After 9-wk LZ treatment, we observed that LZ could decrease estrogen level in laying hens. As a result, both the plasma tartrate-resistant acid phosphatase and bone Gla protein activities were suppressed significantly. In addition, carbonate substitution was inhibited significantly in humerus and femur confirmed by Raman spectroscopy. Meanwhile, the mineral density and yield load capacities of humerus and femur were improved. This study demonstrated that the high crystallinity and low carbonate substitution were tightly correlated with the relatively enhanced mechanical properties. Moreover, it elucidated biochemical mechanisms of estrogen in regulating mineralogical and mechanical properties of bones in laying hens.

The Influence of the Partial Replacing of Inorganic Salts of Calcium, Zinc, Iron, and Copper with Amino Acid Complexes on Bone Development in Male Pheasants from Aviary Breeding.

Abstract
Simple Summary A significant problem of birds reared in farms and then reintroduced to natural living environment is their survival, which is usually much lower than that of the free-living ones. Behavioral and physiological deficiencies rather than morphological anatomy decide about failure, nevertheless, the birds’ body condition, including quality and maturity of skeletal system, are also important. In this context, the problem of proper nutrition for growing game birds is a major one. The level and source of microelements, as well as the source of protein are the main factors affecting bone growth in young captive-reared birds. Since calcium, zinc, iron, and copper are critical nutrients in all practical diets, this experiment was undertaken to determine the possibility of the partial inclusion of organic forms of these elements to the diet of pheasants in order to improve their bone development and survival. Abstract This study analyzed the effects of partial replacing of Ca, Fe, Zn, and Cu salts with glycine chelates on the measures of bones health in 16-week-old captive-reared male pheasants, allocated to one of the three experimental groups supplemented with Ca, Fe, Zn, and Cu in forms of inorganic salts (the control group) or groups receiving from the ninth week 25% and 50% of supplemented elements as glycine chelates. At the end of rearing birds receiving chelates were heavier (p < 0.001) and their tibia showed an increase of numerous mechanical parameters: yield and ultimate force (p = 0.028, p < 0.001, respectively), stiffness (p = 0.007), Young modulus (p < 0.001), compared to the control animals. The bones of birds receiving chelates in 50% were also heavier (p < 0.001) and longer (p = 0.014), with thinner cortical bone in midshaft (p = 0.027) and thicker proximal trabeculae (p < 0.001) compared to the control. While both doses of chelates increased mineral density in midshaft (p = 0.040), bone content of Cu and Zn decreased (p = 0.025, p < 0.001, respectively). The content of immature collagen in cancellous bone and articular cartilage increased in groups receiving chelates (p < 0.001, p = 0.001, respectively). In conclusion, glycine chelates probably enhanced development of the skeletal system in male pheasants as bones were denser and more resistant to mechanical damage.
