“…In this current investigation, the relative liver weight tended to be lower in the treated as compared to the control broilers. A previous study by Vahdatpour et al (2008) showed the inverse relationship between abdominal fat content and liver weight, which is in line with the results of our current study. It was most likely that the supply of lipids from peripheral tissues (including from the abdomen) to the liver was reduced, due to the low serum HDL concentration, causing a decrease in liver fat deposition (Vahdatpour et al, 2008).…”

The study aimed to investigate the effect of dietary administration of Acalypha australis L. leaf extract, whey powder, or a combination of both on the growth, physiological condition, and carcass traits of broilers. A total of 392 broiler chicks was divided into four groups based on a fully randomized design, including (1) control (C, basal feed without additives), (2) basal feed supplemented with 1% Acalypha australis L. leaf extract (AALE), (3) basal feed with 1% whey powder (WHEY), and (4) basal feed with 1% Acalypha australis L. extract and 1% whey powder (AALEWHEY). Samples (i.e., internal organs, blood, intestinal digesta, small intestinal segments, and breast and thigh meats) were collected on day 33. Data were treated with an analysis of variance followed by Duncan's multiple analysis. Treatments did not affect body weight, feed intake, and feed conversion ratio (p>0.05). Abdominal fat was higher in the treated broilers than in the control (C) (p<0.05). The serum high-density lipoproteins (HDL) were lower in AALE, WHEY, and AALEWHEY groups than in the control (C) (p<0.05). Serum creatinine concentrations were higher in WHEY and AALEWHEY groups than in C and AALE groups (p<0.05). The AALE, WHEY, and AALEWHEY groups had higher duodenal villi height than C group (p<0.05). The villi height to crypt depth ratios were higher in the jejunum of the WHEY and AALEWHEY group than in the C group (p<0.05). The pH of breast meat was higher in the C group than in AALE and AALEWHEY groups (p<0.05). The lightness values of breast meats were lower in the AALEWHEY group than in the other groups (p<0.05). The redness values of breast meats were lower in the C group than in the AALE, WHEY, and AALEWHEY groups, while the yellowness values were lower in C and AALE groups than in WHEY and AALEWHEY groups (p<0.05). The pH values of thigh meats were higher in the AALE group than in control (C), WHEY, and AALEWHEY groups (p<0.05). In conclusion, the treatment of broilers with leaf extract of Acalypha australis L., whey powder, or a combination of both improved intestinal morphology and meat quality without affecting the growth performance of broilers.

“…The abdominal fat % was significantly decreased by reduced energy level, but it was increased by emulsifier inclusion in the present study. Indeed, a higher rate of dietary metabolizable energy can increase abdominal fat [20,21]. Similarly, Zaman et al [22] reported that abdominal fat was increased by using diets with high metabolizable energy content.…”

To investigate the influence of emulsifiers on broilers fed low-energy diets, the birds were distributed into three sets—the control was fed the basal diet, the second group was fed diets 50 kcal/kg less than control, and the third group was fed diets 50 kcal/kg less than control and supplemented with 500 g/ton of emulsifiers. The used mixture of exogenous emulsifiers contains phosphatidyl choline, lysophosphatidyl choline, and polyethylene glycol ricinoleate. Although the feed intake was not meaningfully affected by dietary low-energy level with emulsifier inclusion (P = 0.42), the weight gain and FCR were clearly enhanced (P = 0.005 and P = 0.044, respectively). Protein and lipids utilization were decreased by reducing energy level, but they were increased by emulsifier supplementation (P = 0.022 and P = 0.011, respectively). Liver thiobarbituric acid-reactive substances (TBARs) and muscle palmitic acid concentrations were decreased by reducing the energy level and emulsifier’s supplementation (P = 0.014 and P = 0.042, respectively). However, muscle total lipids and α-tocopherol, oleic acid, linoleic acid, and α-linolenic acid were not affected by dietary treatments (P > 0.05). Interestingly, the plasma total cholesterol, HDL-cholesterol, total protein, and globulin were decreased in the low-energy group without emulsifier but they were increased by emulsifier supplementation (P = 0.008, P = 0.005, P = 0.037, and P = 0.005, respectively). It could be concluded that the mixture of emulsifier supplementation to low-energy diets enhanced fat utilization and resulted in positive effects on the growth performance, nutrient utilization, lipid peroxidation, and modified plasma lipid profiles in broilers. Getting such benefits in broilers is a necessity to reduce the feed cost and consequently the price of the product, which will lead to improved welfare of mankind.

“…The dressed weight (head, feather, leg, and internal organs were removed), liver, kidney, abdominal fat pad (from the proventriculus surrounding the gizzard), and gizzard were obtained and recorded. They were expressed as a percentage of live weight (Tohid et al, 2008;Tang et al, 2011;Leke et al, 2018). Whole breast, thigh drumstick, and wings yield were manually cut and weighed and were expressed of carcass weight (Freitas et al, 2018: Reyes et al, 2018.…”

One-hundred male broiler chickens (Cobb500) were assigned randomly in a completely randomized design (CRD) into four dietary treatment groups to determine the effects of various components (whole kernel, kernel oil, kernel defatted) of candlenut (Aleurites moluccana) kernel on growth performance, carcass yield, and proximate and fatty acid composition in meat during the grower-finisher stage. Each treatment consisted of 5 replicates with 5 birds for each replications. From 21 to 42 days of age, the birds were offered either one of the following dietary treatments namely; Basal diet containing no candlenut kernel (T1), Basal diet containing 2.5% whole candlenut kernel (T2), Basal diet containing 2.5% candlenut kernel oil (T3), and Basal diet containing 2.5% candlenut kernel defatted (T4). The significant difference was determined when the probability level was p<0.05. Birds fed the experimental diets showed no significant difference on growth performance, carcass yield, and proximate and fatty acid compositions in meat. However, birds fed diets containing various components of candlenut had small effect on reducing feed intake, decreasing crude protein and crude fat contents in meat, and increasing total C18:2n-6 and n-6 PUFA. In conclusion, supplementation of various components of candlenut kernel in broiler diet did not improve growth performance, carcass yield, and proximate and fatty acid compositions in meat.
