Context Broiler meat with excessive of fat and saturated fatty acids content has serious health implication for consumers. The accumulation of abdominal fats in broiler chickens constitutes a loss of dietary energy and also reduces carcass yield. Oil rich in unsaturated fatty acids and l-arginine are effective for reducing fat deposition and improve meat quality. Aims The aim of this study was to examine the effects of supplementation of l-arginine (l-Arg) with four combinations of palm oil (PO) and sunflower oil (SO) on growth performance, carcass yield, fat deposition, lipogenic gene expression and blood lipid profile in broiler chickens. Methods A total of 180 1-day-old chicks (Cobb 500) were randomly assigned to five dietary treatments as: T1, 6% PO (control); T2, 6% PO + 0.25% l-Arg; T3, 4% PO + 2% SO + 0.25% l-Arg; T4, 2% PO + 4% SO + 0.25% l-Arg; and T5, 6% SO + 0.25% l-Arg. Key results Birds fed l-Arg and combinations of PO and SO had higher weight gain at starter and finisher period compared with the control. The carcass yield increased, and relative abdominal fat reduced in broiler fed with combinations of l-Arg and increased level of SO in the diet. The concentration of oleic, palmitoleic and total monounsaturated fatty acids in liver tissue decreased by addition of l-Arg in broiler diet. The palmitic and total saturated fatty acid decreased, and total unsaturated fatty acid and polyunsaturated fatty acids increased in liver tissue when PO replaced progressively by SO supplemented with l-Arg in the diet. The acetyl-CoA carboxylase , stearoyl-CoA desaturase and fatty acid synthetase gene expression tended to decrease by supplementation of l-Arg with an increased level of SO compared with control. Conclusion Supplementation with l-Arg and combination of PO and SO at the ratio of 4:2 could inhibit lipogenesis and subsequent lower abdominal fat deposition and enhance growth performance and carcass yield in broiler chickens. Implications Ratio of PO and SO, 4:2 with l-Arg supplementation in the dietary of broiler chickens can contribute to a better growth performance, lesser fat deposition and greater carcass yield.

The use of high fiber agricultural byproducts in poultry nutrition can help not only to reduce feed cost but also to promote gastrointestinal functionality and growth performance and enhance environmental sustainability. This study was conducted to examine the effect of oat hulls (OH) incorporated in the diet or fed as free choice on growth performance, intestinal morphology, cecal short chain fatty acids (SCFA) production and carcass yield of broiler chickens. Day old broiler chickens were assigned to 4 dietary treatment groups which consisted of a corn–soybean meal–wheat based diet (Basal), Basal + bacitracin methylene disalicylate (BMD), Basal + 3% OH (3% OH) and Basal + free choice OH (FCOH). Each group had six replicate pens of 27 chicks and were raised for 39 d. Feed intake (FI), body weight gain (BWG), and feed conversion ratio (FCR) were determined weekly for each pen. One chicken/pen was slaughtered on d 36 to determine organ weights, jejunal morphology, digesta pH and cecal SCFA and two chickens/pen were slaughtered on d 39 to determine carcass weight and yield. Diet had no effect on FI, except on d 28, when the FCOH group had higher FI than the 3% OH groups. During the starter phase, chickens fed 3% OH had the highest BWG and lowest FCR, which were significantly different (p < 0.05) from those fed FCOH. Chickens fed 3% OH had the highest slaughter, hot carcass, and cold carcass weights, which were significantly different (p < 0.05) from those fed FCOH. Diet had no effect on jejunal villus height and crypt depth, ileal and cecal digesta pH, and cecal SCFA. Chickens fed FCOH had a larger (p < 0.0001) gizzard weight and showed a tendency to have a larger (p = 0.09) ceca weight than other treatment groups. In conclusion, the inclusion of 3% OH in an antibiotic-free diet has the potential to enhance growth performance, while free choice OH increases the gizzard weight of broiler chickens.

Humic substances (HS) from different sources have been evaluated to replace or reduce the use of growth promoter antibiotics (GPA) in the feeds of broiler chickens. The objective was to evaluate the growth performance, tibia measurements, nutrient balance, meat quality, and microbiological status of broiler fed with an HS extract (EHS) under ad libitum (ADLIB) or feed restriction (REST). Individually caged broilers (n = 180, 14–35 day of age) were assigned to a factorial arrangement of three dietary treatments: (1) positive control with bacitracin methylene disalicylate (BMD) and salinomycin; (2) negative control without BMD nor salinomycin, and (3) same as negative control with 0.25% EHS, and two feeding regimens 1) ADLIB or REST for 24 h on d 1, 7, and 14. Results were subjected to ANOVA. Positive control and EHS-fed broilers showed higher carcass yield (p < 0.05) and lower oocyst excretion (p < 0.01) compared to negative control birds. Lactic acid bacteria (LAB) and Clostridium perfringens (C. perfringens) were higher in negative control and EHS-broilers compared to positive control (p < 0.01). In conclusion, higher carcass yield, lower C. perfringens and oocyst excretion were found in positive control and higher carcass yield, higher LAB and lower oocyst excretion were found in EHS-fed broilers. Broilers subjected to REST had reduced growth performance and meat quality. In conclusion, EHS could be used to increase the carcass yield and beneficial LAB in broilers.
