Abstract
This study aimed to explore the effects of different lipid sources on the performance, blood lipid parameters, immune system activity, and the expression of TNFα and TLR4 genes in broiler chickens. A total of 500 one-day-old male chicks of the ROSS 308 commercial strain were allocated into four treatment groups with five replicates each (each replicate comprised of 25 chickens), following a randomized design. The treatments were as follows: (1) a diet incorporating palm oil (PO, a source of saturated fatty acids); (2) a diet incorporating flaxseed oil (FO, a source of omega-3); (3) a diet incorporating soybean oil (SO, a source of omega-6); and (4) a diet incorporating olive oil (OO, a source of omega-9). According to the findings, the broiler chickens exhibited a significant increase in body weight gain (BWG) throughout the study when their diet consisted of unsaturated oils, as opposed to a diet including PO. Conversely, the feed conversion ratio (FCR) significantly decreased (P<0.01). The treatment with FO resulted in the highest percentage of lymphocytes and antibody titers against Newcastle and Gumboro diseases, showing a significant difference compared to the treatment with PO (P<0.01). Moreover, the relative expression of TNFα and TLR4 genes was the lowest following the FO treatment, indicating a significant decrease compared to the treatment with PO. Overall, the present findings demonstrated that incorporating omega-3 fatty acids into the diet was more effective in enhancing the growth performance, immune system, and health of broiler chickens.

Abstract
The objective of this study was to determine the effects of different lipid sources, with or without a probiotic, on the gastrointestinal tract, immune system and blood parameters of Ross 308 male chickens. In this study, 360 one-day-old chickens were randomly allotted to six treatments with six replicates. Experimental diets were: (1) control (CTL); (2) a diet containing 30 g/kg lipid from tallow (CTL+TLW); (3) a diet containing 30 g/kg lipid from soybean oil (CTL+SO); (4) the basal diet plus a probiotic (CTL+PRO), (5) a diet containing 30 g/kg tallow plus probiotic (TLW+PRO); and (6) a diet containing 30 g/kg soybean oil plus probiotic (SO+PRO). The percentage of liver and jejunum in the treatments that used tallow alone or tallow with probiotics had a significant increase as compared to the control. The villus height and crypt depth of the ileum and villus height/crypt depth in the treatments that used soybean oil and probiotic alone had a significant increase compared to the control. The weight of the spleen, bursa of Fabricius, and thymus in the treatments that used probiotics had a significant increase compared to the control. The amount of alkaline phosphatase and alanine aminotransferase as well as triacylglycerol in the treatment containing probiotic and its mixture with soybean oil had the least significant difference with the control. The results showed that the use of soybean oil, probiotics, and their mixture can improve intestinal morphology, strengthen the immune system, and reduce liver enzymes in chickens.

Abstract
Several genetically modified (GM) plants have been produced and approved by regulatory agencies worldwide for cultivation and commercialization. Soybean and its by-products are major components of poultry diets and approximately 74% of world production is obtained from GM soybean events. The aim of this study was to evaluate the nutrient composition of DP-3Ø5423-1 extruded full-fat soybean meal (FFSBM) and near isoline non-GM control FFSBM included in broiler diets. Also assessed were their effects on bird performance, body composition, intestinal morphology, tissue fatty acid profile, and mRNA abundance of fatty acid metabolism markers. A total of 480 Ross 308 d of hatch birds were randomly allocated to 24 floor pens in a 2 × 2 factorial arrangement with diet and gender as main factors. Birds were fed diets containing 20% of either DP-3Ø5423-1 or control FFSBM for 35 d. Data were subjected to a 2-way ANOVA using the GLM procedure of JMP (Pro13). No significant interaction (P > 0.05) was observed between treatment groups in terms of performance and carcass composition. Morphological measurements of the jejunum and ileum were not influenced by the SBM treatments. Dietary addition of the DP-3Ø5423-1 FFSBM resulted in higher monounsaturated fatty acid composition of the thigh muscle and abdominal fat. Moreover, dietary treatment had no significant impact on the mRNA abundance of metabolic markers ACCα, FAS, MTTP, SREBP1, PPARα, PPARγ, AMPK-α1, SOD, CAT, and GPx in the liver. In conclusion, our results showed that DP-3Ø5423-1 extruded FFSBM is nutritionally equivalent to non-GM near-isoline counterpart with a comparable genetic background as evidenced by feed analyses except for fatty acid composition. Furthermore, the findings of this study clearly indicate that the examined DP-3Ø5423-1 FFSBM yields similar bird performance as conventional FFSBM.

Crantz) as Feedstuffs in Meat Type Poultry Diet: A Source of Protein and n-3 Fatty Acids. Animals (Basel) 2022; 12:295. [PMID: 35158619 PMCID: PMC8833380 DOI: 10.3390/ani12030295] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/21/2021] [Revised: 01/16/2022] [Accepted: 01/21/2022] [Indexed: 02/04/2023] Open
Abstract
Camelina seed or seed processing derivatives, i.e., cake, are cheap alternative protein feed ingredients for meat type poultry. Camelina is an oilseed crop containing 36.8% oil in seeds, while in the cake the oil content accounts for 6.4-22.7%. If compared with other Brassicaceae family plants, camelina is distinguished by a unique fatty acid composition, because the content of α-linolenic fatty acid (C18:3n-3; ALA) varies from 25.9 to 36.7% of total fatty acids. The total tocopherol content in camelina oil and cake are, respectively, 751-900 and 687 mg/kg. Addition of camelina to poultry nutrition increases the amount of n-3 polyunsaturated fatty acids (PUFA) in poultry meat and liver. The content of ALA in chicken muscles increases by 1.3-4.4, 2.4-2.9 and 2.3-7.2 times after supplementing chicken diets with, respectively, camelina cake (8-24%), seed (10%), and oil (2.5-6.9%) in comparison with the control group. Camelina cake (5-25%), seed (10%) and oil (2.5-4%) inclusion in chicken diets results in 1.5-3.9 times higher total n-3 PUFA content in muscles and liver. Meanwhile, supplementation of chicken diets with camelina oil (4-6.9%), seed (5-10%) and cake (5-25%) results in, respectively, a 1.8-8.4, 1.6-1.9 and 1.3-2.9 times lower n-6/n-3 PUFA ratio in muscles, and 3.29 times lower n-6/n-3 PUFA ratio in the liver. After inclusion of different amounts of camelina cake in chicken diets, a healthy for human nutrition n-6/n-3 PUFA ratio from 1.6 to 2.9 was found in chicken muscles.

Abstract
This study aimed to evaluate the effect of four combinations of dietary linseed oil and lysine mixtures on performance, fatty and amino acid profiles, oxidative stress biomarkers, cell energy and meat quality parameters of broiler chickens. One hundred and sixty broiler chicks were allocated into four groups. Birds of groups 1–4 were fed diets containing optimum lysine and 2% of linseed oil, optimum lysine and 4% of linseed oil, high lysine and 2% of linseed oil, and high lysine and 4% of linseed oil, respectively, for a period of 35 days. High linseed oil or lysine levels did not affect the performance of the tested birds, but the high level of dietary linseed oil decreased the concentrations of muscles’ saturated fatty acids (SFA). The highest values of ω-3 polyunsaturated fatty (ω-3 PUFA) and arachidonic acids with lowest levels of monounsaturated fatty (MUFA) were detected in the muscles of birds fed diets containing high linseed oils and/or lysine levels. High linseed oil or lysine levels provided the best essential amino acid profile and improved antioxidant components as well as cell energy, and tenderness and redness of the meat. Conclusively, high dietary lysine and linseed oil combinations improved the nutritional value, antioxidant status and cell energy of broiler chickens’ meat.

Abstract
Simple Summary Recently, there has been increasing interest in the use of insects as an alternative sustainable source of protein and fat in animal feed to improve animal production and maintain ecological sustainability. Palm oil is commonly used in broiler chicken nutrition; however, due to the environmental footprint, consumers have formed negative opinions regarding its applications. Therefore, alternatives to palm oil are urgently needed. The present study was conducted to evaluate the effects of Tenebrio molitor oil as a total replacement for palm oil and poultry fat in broiler chicken diets on chicken performance, nutrient digestibility, pancreatic enzyme activity, various blood parameters and lipid fatty acid compositions of liver and breast muscle tissues. Based on the obtained results, T. molitor oil did not show any adverse impacts on performance and improved the fatty acid profiles of liver and breast muscle tissues. In conclusion, T. molitor oil may be a sustainable alternative to palm oil in broiler chicken nutrition. Abstract This study was conducted to evaluate the effects of Tenebrio molitor (TM) oil as a total replacement for palm oil and poultry fat in broiler chicken diets on growth performance, nutrient digestibility, pancreatic enzyme activity, selected blood parameters and the lipid fatty acid compositions of liver and breast muscle tissues. A total of 72 seven-day-old female Ross 308 broiler chickens were used. The birds were randomly distributed into three groups with 12 replicates each, using two birds per replicate for 30 days in metabolic cages. The basal diet was supplemented with 5% palm oil, poultry fat or TM oil. There was no effect (p > 0.05) caused by the dietary oil replacement on the birds’ performance and apparent nutrient digestibility. Liver size (p = 0.033), the concentration of hepatic triglycerides (p = 0.049) and total cholesterol (p = 0.048) were reduced by TM oil supplementation. Furthermore, TM oil supplementation increased n-3 and n-6 fatty acids (p = 0.006; p < 0.001, respectively) in breast muscle tissue. In conclusion, the use of TM oil in broiler chickens’ diets did not show any adverse effects on performance, nutrient digestibility and blood biochemical parameters. Moreover, TM oil supplementation improved the fatty acid profiles of liver and breast muscle tissues.

Abstract
Objective Ozone is considered a strong antimicrobial agent with numerous potential applications in the food industry. However, its high oxidizing potential can induce alterations in foods by acting on the unsaturated fatty acids. The aim of this study was to investigate the effect of ozonation on the oxidative stability of chicken breast meat obtained from animals subjected to different feeding strategies. Methods Samples were obtained from commercial hybrid chickens (ROSS 508), some of which were nourished with a feed enriched with fats of animal origin, while the lipid source was vegetal for the remaining birds. Samples of meat belonging to both groups were treated with ozone and then analysis was performed to evaluate alterations in physical properties, lipid content, fatty acid profile, and oxidation stability. Results Ozone induced a significant reduction in drip loss in meat samples obtained from animals nourished with vegetable fats; this nutritional strategy also produced meats leaner and richer in polyunsaturated fatty acids. Thiobarbituric acid reactive substances, useful for the assessment of lipid oxidation, were higher in samples obtained from animals fed with vegetable fats with respect to diet based on the addition of animal fats. Conclusion The ozone treatment improved the physical parameters of meat samples obtained from animals fed with vegetable fats, however the same samples showed a higher lipid oxidation compared to what observed in the case of the dietary intake of animal fats, probably as a consequence of the marked increase in polyunsaturated fatty acids which are more susceptible to peroxidation.

Abstract
Omega-3 polyunsaturated fatty acids (n-3 PUFA) are linked to a variety of health benefits against human disorders and disease. However, the typical western diet is generally low in n-3 PUFA and high in n-6 PUFA, suggesting that the recommended intake of these essential fatty acids is seldom achieved. Therefore, dietary enrichment of animal meat and eggs with n-3 PUFA could help increase consumption of these fatty acids. Fish oils and microalgae (MA) are rich sources of long chain n-3 PUFA, specifically eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). Feeding these marine products has been shown to increase DHA content of tissues and yolk, however, this may also lead to an increased requirement for anti-oxidants to prevent oxidative deterioration and associated negative sensory attributes. Nonetheless, increased DHA has been linked to promising results in animal growth, fertility, immunity and bone strength in both pigs and poultry. These findings suggest that feeding DHA-rich ingredients to mono-gastric can enrich human diets as well as providing additional benefits to the animal.
