This investigation evaluated, in broiler chickensPectoralisandGastrocnemiusmuscles, the effect of the dietary supplementation with sodium selenite (0.3 ppm) versus selenomethionine (0.3 ppm), on the fatty acids composition, lipids indices, and enzymes indexes for desaturase, elongase, and thioesterase. The selenium reduced, in both muscles, the content of atherogenic fatty acids, C14:0 and C16:0, while it increased the C18:1 level. On the other hand, selenium increased, in both muscles, the content of C18:3n3 and EPA, but not DPA and DHA. No selenium effect was detected for PUFA/SFA, n-6, n-3, n-6/n-3, and atherogenic and thrombogenic indices. As for the enzyme indexes, a selenium effect is only detected for thioesterase. Taken together, the results highlight the potential effect of dietary selenium, mainly selenomethionine, in the modulation of the composition of fatty acids in chicken meat, in particular, reducing the content of atherogenic fatty acids and increasing the health promoting n-3 PUFA.

Dietary Treatments

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. The aim of this study was to determine the effect of vitamin E and polyphenols on the antioxidant potential and meat quality of broiler chickens fed diets supplemented with low-quality oil. The experimental materials comprised 120 male Ross 308 broilers (six treatments, 10 replications, two birds per replication). Dietary supplementation with vitamin E and/or polyphenols was applied in the following experimental design: group I (negative control) – without supplementation without low-quality oil; group II (positive control) – without supplementation + low-quality oil; group III – supplementation with 100 mg kg−1 of vitamin E+ low-quality oil; group IV – 200 mg kg−1 of vitamin E + low-quality oil; group V – 100 mg kg−1 of vitamin E and 100 mg kg−1 of polyphenols + low-quality oil; group VI – 200 mg kg−1 of polyphenols + low-quality oil. Rapeseed oil oxidised under laboratory conditions was added to the diets of broiler chickens from groups II to VI. The applied antioxidants had no effect on the growth performance of chickens fed oxidised oil. Increased dietary inclusion levels of vitamin E and/or polyphenols improved the antioxidant status in the blood and increased the content of non-enzymatic antioxidants in the liver and breast muscles of broilers fed low-quality oil. The tested antioxidants had no influence on carcass quality parameters in chickens fed oxidised oil. However, birds fed diets with the addition of vitamin E were characterised by a higher gizzard weight and higher pH of gizzard digesta. Dietary supplementation with vitamin E and polyphenols or polyphenols alone contributed to a lighter colour and lower pH of breast muscles and an increase in the content of fat and ash in the breast muscles of broilers fed oxidised oil. The breast muscles of birds given 100 or 200 mg kg−1 of supplemental vitamin E were characterised by higher concentrations of n-6 polyunsaturated fatty acids (PUFAs) and hypocholesterolemic fatty acids (DFAs), a more desirable DFA∕OFA ratio, and a lower atherogenicity index (AI). Polyphenols combined with vitamin E can be a valuable component of diets for broiler chickens when the problem of low-quality oil occurs.

The research was conducted to study the effect of feeding broiler chickens on diets containing isomaltooligosaccharides on the growth performance, carcass traits and immune response. 90-one day old broiler chicks were used according to completely randomized two treatment groups and one control, 30 birds each. Birds fed ad-libitum on basal starter and grower-finisher diets for 35 day. Diets of treatment`s groups contained 0.5 g/Kg and 1 g/Kg of Isomaltooligosaccharides, while the control group fed on the basal diets without Isomaltooligosaccharides supplementation. Dietary supplementation of broiler chickens with Isomaltooligosaccharides improved body weight, feed conversion, carcass traits, two lymphoid organs weight and log antibody titer against avian flu vaccine. Most of the highest values were for birds fed low levels of Isomaltooligosaccharides. Feed intake decreases as Isomaltooligosaccharides level increases. Dietary supplementation with Isomaltooligosaccharides did not affect the lipids profile (triglycerides, total cholesterol, LDL and HDL), however the blood VLDL levels decreased with increased levels of Malondialdehyde and Glutathione reductase. Collectively, Dietary supplementation of broiler chickens with 0.5 g/Kg diet of Isomaltooligosaccharides improved growth performance, carcass traits and immune status.

Abstract The objective of this study was to evaluate the effects of dietary supplementation of coated omega-3 fatty acid (n-3 CFA) by corn cob power silica on performance of weaning pigs. A total of 200 weaned pigs [(Landrace x Yorkshire) x Duroc, average initial body weight at 6.97 ± 1.22 kg] were randomly assigned to four experimental treatments in a 6-week experiment in 3 phases as follows: CON, basal diet; 2) 0.3CFA, CON + phase 1(0.3% n-3CFA), phase 2(0.2% n-3CFA), phase 3(0.1% n-3CFA); 3) 0.6CFA, CON + phase 1(0.6% n-3CFA), phase 2(0.4% n-3CFA), phase 3(0.2% n-3CFA); 4) 0.9CFA, CON + phase 1(0.9% n-3CFA), phase 2(0.6% n-3CFA), phase 3 (0.3% n-3CFA). Each treatment had 10 replicates with 5 pigs (three gilts and two barrows) per replicate. The data were analyzed using the GLM procedure of SAS as a randomized complete block design. Pen served as the experimental unit. Linear, quadratic and cubic polynomial contrasts were used to examine effect of dietary treatment with coated n-3FA in the basal diet. Variability in the data was expressed as the standard error of means and P&lt; 0.05 was considered to statistically significant. Increasing the level of n-3CFA in the diet linearly increased ADG and G/F of pigs (Table 1). Increasing the level of n-3CFA showed a linear increment in the digestibility of DM (83.59, 84.38, 85.13, 85.89 %) whereas nitrogen digestibility (81.79, 82.38, 82.96, 83.64 %) showed a trend (linear effect, p=0.0594) at the end of experiment. The fecal lactobacillus count was increased (7.22, 7.27, 7.33, 7.35 log10cfu/g) with the increase in the supplemental level of n-3CFA (linear effect; p&lt; 0.05). However, there were no differences in the concentration of serum haptoglobin, or fecal E. coli, Clostridium and Salmonella counts despite the increase in n-3CFA levels in the diet. Supplementation of the diet with coated n-3 fatty acids positively affected growth performance and digestibility of dry matter and nitrogen, and enhanced the count of lactobacillus in weaning pigs.
