“…Sci., 9 (3): 144-154, 2015 At present, feed restriction (Fisher, 1984) and the inclusion of dietary additives that promote lean growth at the expense of fat deposition are the two commercially successful methods in use. According to the recent review by Fouad and El-Senousey (2014), both the methods have shown a decrease in body fat, but many reports have shown negative effect on body weight.…”

Accumulation of body fat is the major problem associated with initiation of various diseases in fast growing broiler chickens. Methods to restrict the accumulation of body fat have met with limited success. The objective of this study was to evaluate the effect of Avocado Non-Saponifiable Fraction (NSF) in broiler chicken (from day 14 for 27 days) on body fat accumulation, growth performance, organ weight and plasma lipid profile. Supplementation of avocado NSF for 27 days has resulted in positive changes in plasma lipid profile with 50% decrease of abdominal fat and 33.8% increase in body weight compared with normal control chickens. The Avocado NSF improved body composition in broilers through higher lean-to-fat ratio and hence has a potential to improve overall health profile and reduce metabolic diseases in chickens.

“…In broilers, fatty acid synthesis occurs mainly in the liver, and the adipose tissue is the primary site of fat storage as triglycerides, especially the abdominal fat tissue (Huang et al, 2008;Fouad & El-Senousey, 2014). Therefore, we investigated the effect of the dietary supplementation of FCSM on lipid-related gene expression of acetyl CoA carboxylase (ACC), fatty acid synthase (FAS), lipoprotein lipase (LPL), peroxisome proliferator-activated receptor alpha (PPAR-α), and liver fatty acid-binding protein (L-FABP) in liver tissue, as well as LPL and peroxisome proliferator-activated receptor gamma (PPAR-γ) in the abdominal fat tissue of broiler chickens.…”

Fermented cottonseed meal (FCSM) is widely used in poultry diets in China. This study was conducted to investigate the effect of FCSM on lipid-related gene expression in broilers. Initially, 180 broiler chickens (21-days-old, equal number of males and females) were randomly divided into three groups, with six pens per group and 10 birds per pen. The chickens in the control group were fed a diet containing unfermented cottonseed meal, and those in the treatment groups were fed with diets including either CSM fermented by Candida tropicalis (Ct group) or CSM fermented by Candida tropicalis plus Saccharomyces cerevisae (Ct-Sc group) until 64 days old. The results revealed that, compared with the control group (p<0.05), the mRNA expression of peroxisome proliferator-activated receptor alpha (PPAR-α) and lipoprotein lipase (LPL) were upregulated in the livers of Ct-Sc males. The expression of PPAR-α was also upregulated in the livers of Ct females. The expression levels of acetyl CoA carboxylase (ACC) and LPL in the liver of males and the expression of PPAR-α in the liver of females were significantly different between the Ct and Ct-Sc groups (p<0.05). However, gene expressions of fatty acid synthase (FAS) and liver fatty acid-binding protein (L-FABP) in the liver were not altered when the broilers were fed FCSM-supplemented diets (p>0.05). Likewise, the expressions of peroxisome proliferator-activated receptor gamma (PPAR-γ) and LPL in the abdominal fat were not altered by the FCSMsupplemented diets (p>0.05). The results in this study indicate that CSM fermented by Candida tropicalis and Saccharomyces cerevisiae effectively regulated the genes involved in fatty acid β-oxidation and triglyceride hydrolysis in male broiler chickens. Furthermore, the effects of the FCSM-supplemented diets were significantly different between bird sexes and between yeast strains used in the fermentation process.

“…This may be due to high levels of fat in BSC compared to SBM, which is about twice the amount of energy compared to carbohydrates. Since broilers primarily consume feed in order to satisfy their energy needs, the excess energy will be converted to fat which act as energy reserves for the chickens (Fouad and El-Senousey, 2014). Although the excessive fat deposition is an unfavorable trait in broiler industry, its organoleptic effects on the flavor of the meat is favorable.…”

Due to competition between humans, industry and livestock for crop usage, there is need to identify alternative plant protein sources readily available and inexpensive. Beniseed (Sesamum indicum L.) cake is considered to replace soybean (Glycine max [L.] Merr.) meal as plant protein source for animal feed. This study was conducted to evaluate substitution effects of Nigerian white beniseed cake (BSC) for soybean cake (SBM) in diets of broilers, and determine optimum substitution levels. Replacement levels of BSC for SBM in diets were 0%, 25%, 75%, and 100%. A 56-d feeding trial was conducted on 264-d old unsexed Cobb broilers, randomly assigned to four treatment groups of 66 birds each, with three replicates of 22 birds each in a completely randomized design. A quadratic type optimization function was used to determine optimum BSC levels that significantly affected growth, carcass and blood indices. Diets 100% BSC had the least body weight at 28 d, final body weight, average daily feed intake (ADFI), and carcass weight (P < 0.05). Diets with 25%, 75% and 100% BSC had higher efficiency factor, abdominal fats and white blood corpuscles than 0% substitution diet (P < 0.05). Diet 25% BSC showed significantly higher dressing percentage (P < 0.05), and diet 0% BSC had higher serum protein and urea compared to the other diets. The quadratic function indicated that ADFI was significantly optimized at 25% BSC+75% SBM, with R 2 = 0.992 and P-value 0.051. The threshold of 25% to 75% substitution levels of BSC can replace SBM in the diets of Cobb broilers without detrimental effects.
