Babatunde OO, Park CS, Adeola O. Nutritional Potentials of Atypical Feed Ingredients for Broiler Chickens and Pigs. Animals (Basel) 2021; 11:ani11051196. [PMID: 33919422 PMCID: PMC8143358 DOI: 10.3390/ani11051196] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/18/2021] [Revised: 04/04/2021] [Accepted: 04/19/2021] [Indexed: 01/10/2023] Open
Abstract
Simple Summary Common feed ingredients such as corn, barley, wheat, soybean meal, and canola meal are used to feed broiler chickens and pigs in various countries around the world. However, due to rising costs and the need to practice sustainable animal husbandry, concerted efforts have been aimed at identifying and examining the nutritional potentials of atypical feed ingredients for pigs and chickens. Although there are some articles and reviews that discuss the potential of a single or few feed ingredients for either chickens or pigs, there has not been an extensive review that integrates information from several alternative feed ingredients for both species in one place. Therefore, this review aims to enumerate several feed ingredients that have shown prospects in supplying either one or more nutrients to pigs and chickens while reducing the dependence on commonly used feedstuff. In addition, feeding practices, merits, and limitations associated with these uncommon feed ingredients are discussed. Furthermore, practical applications of these alternative feed ingredients in relation to either pigs or chickens are briefly examined. Abstract Diets play an important part in monogastric nutrition. This is because diets are comprised of various feed ingredients that supply energy and nutrients required by broiler chickens or pigs for normal growth and development. The main feed ingredients used for formulating diets for pigs and chickens are comprised of cereals and oilseed meals. Corn and soybean meal (SBM) are mostly used in North America for animal feeds. However, due to geographical locations, availability, and cost, ingredients such as wheat, barley, and canola meal are often used for feeding pigs and chickens. Overdependence on common ingredients such as corn and SBM for decades has resulted in rising costs of animal production. Therefore, the need has risen to examine the potentials of alternative feed ingredients capable of supplying the required energy and nutrients for monogastric animals. Research has been carried out to identify and evaluate several uncommon feed ingredients and their utilization by broiler chickens and pigs. Thus, this review enumerates the nutritional potentials of feed ingredients in 4 main nutritional classes using information from articles in peer-reviewed journals. Feeding practices, advantages, and limitations of using certain uncommon feed ingredients are discussed. In addition, species-specific factors in terms of practical applications are explored.

Abstract
Locally grown feed ingredients of high energy and protein content, such as peanuts, maybe economically feasible alternatives to corn and soybean meal in broiler diets. Even though normal-oleic peanuts have been demonstrated to be a viable feed ingredient for poultry, few studies to date have examined the use of high-oleic peanuts (HO PN) as an alternative feed ingredient for broiler chickens. Thus, we aimed to determine the effect of feeding HO PN on broiler performance, nutrient digestibility, and intestinal morphology. Three isocaloric, isonitrogenous experimental diets were formulated with 1) dietary inclusion of ~10% coarse-ground whole HO PN; 2) a corn-soybean meal control diet with 5.5% added poultry fat; and 3) a control diet supplemented with 5.5% oleic fatty acid oil. Three-hundred Ross 708 broilers were randomly placed in 10 replicate pens per treatment with 10 chicks per pen and raised until 42 d. Body weights (BW) and feed intake were determined weekly, and feed conversion ratio (FCR) was calculated. Jejunum samples were collected at 42 d for histomorphometric analysis. Analysis of variance was performed on all variables using a general linear mixed model in JMP Pro14. Broilers in the HO PN group had lower (P < 0.05) BW and higher FCR than other treatment groups at weeks 2 and 6. There were no significant differences in the jejunum villi surface area between the treatment groups. However, broilers fed the HO PN diet had greater (P = 0.019) apparent metabolizable energy relative to the other treatment groups, suggesting improved nutrient uptake of dietary fats and/or carbohydrates in the HO PN treatment group. However, additional studies are warranted to further define the nutritional value of HO PN as an alternative poultry feed ingredient.

Abstract
Early feeding trials using peanut meal prepared from normal-oleic peanuts helped to identify peanuts as a suitable alternative feed ingredient for poultry. Yet no studies to date have examined the use of high-oleic peanuts (HO-PN) as a feed ingredient for meat type chickens. Therefore, this study aimed to determine the effect of feeding whole unblanched HO-PN on the fatty acid profile of the meat produced from broilers. At hatch male chicks were randomly placed in raised wire cages, in 10 replicate pens per treatment with 10 chicks per pen, and fed with one of the 3 isocaloric, isonitrogenous diets ad libitum for 42 days: (1) conventional control of soybean meal + corn, (2) 10 to 12% HO-PN and corn diet, or (3) control diet spiked with ≈6.0% oleic acid oil. All body weights (BW) were collected, and broiler selection for processing was determined by individual BW within one-half a standard deviation of the experiment 42-D mean BW, with one bird selected per pen (10 replicate pens per treatment, 3 treatments, 10 birds selected per treatment, yielding a total sample size of 30 birds). Performance was determined weekly and breast samples were analyzed for fatty acid and amino acid profile. All data was analyzed using analysis of variance, with t-test mean comparisons at P < 0.05. BW were similar between broilers fed the HO-PN and control diet, while feed conversion ratio of broilers fed the HO-PN diet was significantly higher at weeks 2, 4, and 6 in comparison to the other treatments (P ≤ 0.03). Broilers fed with HO-PN diet had reduced carcass and pectoralis major weights in comparison to the other treatments. Chicken breast from broilers fed the HO-PN diet had significantly reduced saturated and trans fatty acid content in comparison to the controls (P ≤ 0.0002). Although additional studies must be conducted, this study suggests that feeding whole unblanched HO-PN to broiler chickens may serve as a means to enrich the meat produced with unsaturated fatty acids.

Abstract
Abstract
Studies on the effects of dried blood plasma on certain health parameters of mink (of the pastel variety) were conducted during lactation and the rearing of the kits. The study included two groups of mink (control group and experimental group). Animals in the experimental group received 0.5 % of dry blood plasma and the control group did not receive the plasma supplement. From the whole blood of both groups the direct and indirect haematological indices were recorded. Also, in both groups, the histopathological and immunohistochemical studies were performed on the: liver, kidneys, lymph nodes, spleen, and intestinal segments. From the experimental group some of the organs examined demonstrated slightly altered histopathology.

Abstract
1. The objective of this study was to investigate how a diet containing spray-dried blood cells (SDBC) (4%) with or without zinc (Zn) would affect the concentration of two histidine heterodipeptides and the antioxidant status of broiler blood and breast muscles. 2. The study was carried out on 920 male Flex chickens randomly assigned to 4 dietary treatments: I - control, II - diet I with SDBC, III - diet I with SDBC and supplemented with Zn and IV - diet I supplemented with L-histidine. Birds were raised on floor littered with wood shavings, given free access to water and fed ad libitum. Performance indices were measured on d 1, 21 and 42. 3. The activity of antioxidant enzymes superoxide dismutase, catalase and glutathione peroxidase was analysed in plasma, erythrocytes and muscle tissue. The total antioxidant capacity of plasma and breast muscles was measured by 2,2-azinobis-(3-ethylbenzothiazoline-6-sulphonic acid) (ABTS) and 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging ability, as well as by ferric reducing antioxidant power (FRAP). Carnosine/anserine content of meat and plasma were determined using HPLC. Diets and breast muscles were analysed for amino acid profile and selected microelement content. 4. Histidine supplementation of the diet increased glutathione peroxidase activity in plasma and superoxide dismutase activity in erythrocytes. Moreover, the addition of SDBC or pure histidine in the diet increased histidine dipeptide content and activated enzymatic and non-enzymatic antioxidant systems in chicken blood and muscles. However, it led to lower growth performance indices. 5. The enrichment of broiler diets with Zn increased the antioxidant potential and the activity of superoxide dismutase in plasma, which was independent of the histidine dipeptide concentration. Zn supplementation combined with SDBC in a broiler diet led to the increase of superoxide dismutase and glutathione peroxidase activity, but it did not affect the radical-scavenging or ferric iron reduction abilities of muscles.

Abstract
The chemical composition of spray dried porcine blood by-products is characterised by wide variation in crude protein contents. In spray dried porcine blood plasma (SDBP) it varied between 670-780 g/kg, in spray dried blood cells (SDBC) between 830-930 g/kg, and in bone protein hydrolysate (BPH) in a range of 740-780 g/kg. Compared with fish meal, these feeds are poor in Met and Lys. Moreover, in BPH deep deficits of Met, Cys, Thr and other amino acids were found. The experiment comprised 7 dietary treatments: SDBP, SDBC, and BPH, each at an inclusion rate of 20 or 40 g/kg diet, plus a control. The addition of 20 or 40 g/kg of the analysed meals into feeds for very young chickens (1-28 d post hatch) significantly decreased the body weight (BW) of birds. Only the treatments with 40 g/kg of SDBP and SDBC showed no significant difference in BW as compared with the control. There were no significant differences between treatments and type of meal for feed intake, haematocrit and haemoglobin concentrations in blood. Addition of bone protein and blood cell meals to feed decreased the IgG concentration in blood and caused shortening of the femur and tibia bones. However, changes in the mineral composition of bones were not significantly affected by the type of meal used. The blood by-products, which are rich in microelements, improved retention of Ca and Cu only. In comparison to control chickens, significantly better accretion of these minerals was found in treatments containing 20 g/kg of SDBP or 40 g/kg of SDBC. Great variability in apparent ileal amino acid digestibility in chickens was determined. In this respect, some significant differences related to the type of meal fed were confirmed for Asp, Pro, Val, Tyr and His. In general, the apparent ileal digestibility of amino acids was about 2-3 percentage units better in chickens fed on diets containing the animal by products than in control birds.

Abstract
Spray-dried porcine blood plasma (SDBP) or blood cells (SDBC) at amounts of 20 or 40 g/kg were included to the feed mixtures that were given to young chickens within 1-28 (Exp. 1) or 1-30 (Exp. 2) days post-hatch. In comparison with the group fed mixtures containing plant components, chickens fed mixtures supplemented with 40 g/kg of SDBP significantly (p < 0.01) increased the body weight estimated on 14 day of life (Exp. 1). At the age of 28 or 30 days post-hatch, the body weight was improved significantly (p < 0.01 or 0.05) in both experiments. Significant differences (one-factorial anova) in feed conversion among particular feeding groups were stated in Exp. 1 only; however, calculations using two-factorial anova show insignificant differences depending on the used animal meal. In selected blood parameters (IgG, Ht, Hb), insignificant differences between feeding groups were stated. The use of SDBP in feed mixture significantly increased the Na retention in both experiments, and K accretion in Exp. 1 only. Application of SDBC and 40 g/kg of SDBP significantly or insignificantly improved Fe retention. Insignificant diversification of apparent ileal digestibility of nutrients was stated; the crude fat was significantly better digested in treatments fed mixtures with animal meals but kind of animal meal was without any significant effect. Significant differences in digestibility of amino acids were recorded for Pro, Cys, Val, His, Lys and Arg. In chickens fed mixture with SDBC, higher coefficients of apparent digestibility of Cys, Val and His (Exp. 1) and Cys and His (Exp. 2) than in other feeding groups were obtained. The kind of used blood by-products has not affected the histological structure of intestine wall.

Abstract
The aim of the research was to isolate the hemoglobin-degrading bacterial strain to produce fermented blood meal and to characterize the protease produced by this strain. The strain NJM4, a kind of hemoglobin-degrading bacterial strain, was isolated by blood agar plates from slaughterhouse and identified as a Bacillus pumilus by physiological, biochemical, and morphological characteristics and by 16S rRNA gene sequencing. Bacillus pumilus NJM4 could degrade hemoglobin up to 85% in 36 h under the laboratory conditions. The optimal conditions for protease production was achieved at an initial pH level of 8.67, inoculum size of 4%, incubation temperature of 37 °C, and agitation rate 200 rpm. The optimum pH and temperature of hemoglobin-degrading proteases were at 9.0 and 50 °C, respectively. The protease activity was slightly decreased in presence of Ca(2+) and DTT. It was significantly inhibited in the presence of PMSF and EDTA identifying it as alkaline serine-metalloproteinase. Bacillus pumilus NJM4 and hemoglobin-degrading proteases provide potential use for biotechnological process of fermentation and enzymolysis blood meal as animal feed supplement.

Abstract
The study was designed as a 2 x 5 factorial arrangement with main effects of feeding blood meal as a replacement of 0, 25, 50, 75 or 100% of dietary fish meal and the duration of this substitution at 1-42 or 21-42 days of age. One thousand 1 day old male Cobb 500 broiler chicks assigned randomly to each of 40 floor pens (25 birds/pen) and were fed five isonitrogenous and isocaloric feeds formulated to contain 20.38 and 17% crude protein and 2900 and 3000 kcal kg(-1) metabolizable for starter and grower periods, respectively. Duration of dietary manipulation didn't affect the measured parameters. More than 25% blood meal/fish meal substitution ratios significantly increased chickens daily weight gain and decreased the cost of producing a unit of meat. Other traits didn't affect by dietary fish meal/blood meal replacement ratio. Spleen and proventriculus percents and small intestine length affected by level of replacement but didn't follow a distinct pattern. These results indicate that this locally produced blood meal is a suitable substitute for dietary fish meal and a full replacement didn't cause any adverse effect on performance, carcass important traits and dietary nitrogen retention of broiler chickens.

Abstract
Peanut protein is severely limiting in threonine and has been used to create threonine deficiency in animals. The availability of purified threonine at low cost raises the possibility of economically using peanut meal (PNM) and threonine combinations in poultry diets. An experiment was conducted to compare corn and PNM based diets to corn and soybean meal (SBM) based diets at three protein levels (16, 18.5, and 21%) in diets for 22-to-34-wk-old commercial Leghorns. Birds were housed two per cage with four cages per replicate and six replicates per treatment. Feed consumption, egg production, and feed per dozen eggs were almost identical for PNM (93.8 g/hen per d, 92.2 eggs per 100 hens/d, and 1.22 kg/dozen) and SBM (93.7 g/hen per d, 92.2 eggs per 100 hens/d, and 1.22 kg/dozen). Dietary protein level had no consistent effect on any of these parameters but did significantly improve body weight gains and egg weights (1.2 to 2.5 g/egg). PNM-fed hens laid slightly smaller eggs during the first 6 wk (P<0.05), but there were no egg size differences during the last 6 wk of the experiment (P>0.14). PNM-fed hens laid eggs with better interior quality at 26 and 30 wk of age. After 2 wk of storage, Haugh units remained better for eggs from hens fed PNM than SBM when kept refrigerated (4 degrees C; P<0.05) or at room temperature (20 degrees C; P<0.10). Egg specific gravity was slightly lower for hens fed PNM. It is concluded that PNM is an excellent ingredient for laying hen diets.
