“…Interestingly, low levels of dietary FO (such as 2%) have been demonstrated as being more effective than high levels of FO on improving performance [16]. The improved performance by dietary n-3 PUFA supplementation in broilers is also due to the narrowing dietary n-6/n-3 PUFA ratio (close to 4:1 or 2.5:1) and increasing the n-3 PUFA level that could effectively improve immune responses [17]. Moreover, high levels of n-3 PUFA can improve immunity and anti-inflammatory functions by decreasing the contents of inflammatory biomarkers, consequently leading to better performance in broilers [18].…”

Simple Summary:The findings in the current study reveal that dietary fish oil or a combination of linseed oil and microalgae could be effective in improving growth performance, carcass traits, muscle fatty acid deposition, and antioxidant capacity in broilers compared with traditional soybean oil in broilers.Abstract: This study aimed to investigate the efficiency of dietary fatty acids from various sources on growth performance, meat quality, muscle fatty acid deposition and antioxidant capacity in broilers. 126 Arbor Acres broilers (1 d-old, initial body weight of 45.5 ± 0.72 g) were randomly assigned to three treatments with seven cages per treatment and six broilers per cage. The dietary treatments included:(1) corn-soybean meal basal diet containing 3% soybean oil (control diet, CTL); (2) basal diet + 1% microalgae + 1% linseed oil + 1% soybean oil (ML); (3) basal diet + 2% fish oil + 1% soybean oil (FS). The trial consisted of phase 1 (day 1 to 21) and 2 (day 22 to 42). Compared with CTL, broilers fed ML or FS diet showed improved (p < 0.05) average daily gain in phase 1, 2, and overall (day 1 to 42), as well as a decreased (p < 0.05) feed conversion ratio in phase 1 and overall. On day 42, broilers supplemented with FS diet showed increased (p ≤ 0.05) the relative weights of pancreas and liver, as well as higher (p < 0.05) redness value in breast and thigh muscle compared with CTL. Broilers offered ML or FS diet had lower (p < 0.05) the relative weight of abdominal fat and total serum cholesterol content in phase 1, and increased (p < 0.05) contents of serum glucose, n-3 polyunsaturated fatty acids (PUFA), eicosacagetaenoic acid, docosahexaenoic acid, glutathione peroxidase, superoxide dismutase and total antioxidant capacity, as well as lower (p < 0.05) concentrations of malondialdehyde, n-6 PUFA, and n-6/n-3 PUFA ratio in breast and thigh muscle compared with CTL. This research indicates that diets supplemented with fish oil or a combination of microalgae and linseed oil experience improved performance, antioxidant capacities and n-3 PUFA profile in muscle of broilers compared with traditional soybean oil supplemented diets Animals 2020, 10, 508 2 of 13 docosahexaenoic acid (DHA, C22:6n-3), eicosacagetaenoic acid (EPA, C20:5n-3), and alpha-linolenic acid (ALA, C18:3n-3)-as well as an increased ratio of PUFA to saturated fatty acid ratio (PUFA/SFA ratio) and n-3/n-6 PUFA ratio-are necessary and beneficial for broilers and human health [1]. However, the intake of n-3 PUFA in the average human diet is low and the conversion of ALA to EPA and DHA in the human body is also low [2]. Therefore, scientists have recently shown more interest in producing poultry meat products enriched with n-3 PUFA for human consumption [3].The fatty acid composition in the breast and thigh muscles of animals is highly related to the fatty acids in the diet fed to animals [4], so providing animals with diets enriched in n-3 PUFA can be the most practical way to manipulate the n-3 PUFA profiles of meat [5]. Previous studies have sh...

“…The result of this present study agreement with several previous study. In poultry, the consumption of diets high in PUFA, particularly eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), it has been demonstrated to improve body weight gain (27,28). The enrichment n-3 PUFA containing fish oil at 2% and 4% in broiler diets showed increased accumulation of n-3 LC-PUFA in muscle and adipose tissues (27).…”

Background and Objectives: Use of antibiotics as growth promoters in animal feeds has been restricted due to the residues in poultry products such as egg and meat, furthermore to the antibiotic resistant of pathogenic bacteria. The prohibition of their use opens the opportunity for the use of non-antibiotic feed additives such as probiotics. The objectives of this study were to investigate the effect of the addition of Lactobacillus casei WB 315 and crude fish oil (CFO) to diets on growth performance, eicosapentaenoic acid (EPA), docosahexaenoic acid (DHA), low density lipoproteins (LDL), high density lipoprotein (HDL), and cholesterol levesl of broiler chickens. Materials and Methods: In this research, one-day old male broiler chicks were used and divided equally into four groups, namely a basal diet without L. casei WB 315 and without CFO (P0), basal diet supplemented with 0.5% L. casei WB 315 of total broiler basal feed (1.2 × 109 cfu/ml) and without CFO (P1), basal diet supplemented without L. casei WB 315 and 1% CFO of total broiler basal feed (P2), and basal diet supplemented with 0.5% L. casei WB 315 of total broiler basal feed (1.2 × 109 cfu/ml) and 1% CFO of total broiler basal feed (P3) for 35 days. Results: The results of addition 0.5% Lactobacillus casei WB 315 (1.2 × 109 cfu/ml) and 1% CFO of total broiler basal feed after 35 days showed significant difference among treatment in feed efficiency (p<0.05), feed conversion ratio (p<0.05), feed consumption (p<0.05), EPA (p<0.05), DHA (p<0.05), increase HDL (p<0.05), reduced the LDL (p<0.05), and reduce cholesterol (p<0.05) in meat broiler chicken. Conclusion: It is concluded that the addition of L. casei WB 315 and crude fish oil (CFO) could significant improve the growth performance (feed efficiency, feed conversion ratio, feed consumption) and could significantly improve EPA, DHA and increase HDL and decrease LDL in meat poultry product.

“…Average live body weight of ducks was measured at the end of starter and finisher periods and feed intake was recoded at the end of the two rearing periods. And, accordingly, growth performance parameters, as body weight gain, feed:gain ratio and protein efficiency ratio were calculated as we previously reported (Ibrahim et al 2018).…”

This study aimed to determine the effectiveness of guanidinoacetic acid (GAA) with or without methionine (Met) compared to creatine (CREA) at enhancing duck's performance, restoring tissue CREA and improving meat quality. Mulard ducklings (n = 250) were randomly assigned to control (without additives), or control plus CREA, GAA, GAA + 0.2%Met (GAAMet0.2) or GAA + 0.4%Met (GAAMet0.4) groups in a completely random experimental design. Dietary supplementation of CREA or GAA significantly increased (P < 0.05) overall weight gain and improved feed:gain ratio. Supplementation of GAA (especially GAAMet0.4 group) significantly increased (P < 0.05) carcass and breast yield. Meat pH values were higher (P < 0.05) with dietary GAA + Met or CREA. Providing of dietary GAA + Met led to higher levels of plasma CREA than dietary CREA itself. The molecular investigation indicated that dietary CREA or GAA with Met enhanced the gene expression of hepatic insulin-like growth factor-1, growth hormone and muscle myogenin. Finally, dietary GAA + Met was superior to CREA in improving duck's performance based on molecular markers related to growth (IGF-1 and growth hormone) and myogenesis (upregulating myogenin and downregulating myostatin). Although, dietary GAA + Met enhanced muscle's CREA loading than CREA, the long-term GAA supplementation in ducks may induce methyl-groups shortage for protein synthesis, this was resolved with Met addition in our study.
