“…The abdominal fat tissue grows faster compared with other fat tissues (Butterwith, 1989) and it reaches its maximum rate of growth at 42 days of age (Havenstein et al, 2003). It is the key indicator used to judge total body fat (Chen et al, 2011) because it is linked directly to the total body fat content in broiler chickens (Sonaiya, 1985). Our results agreed with previous studies of broiler chickens, pigs and White Pekin ducks (Corzo et al, 2003;Tan et al, 2009;Wu et al, 2011).…”

“…The levels of plasma triglyceride (TG), total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), lowdensity lipoprotein cholesterol (LDL-C) and nonesterified fatty acids (NEFA) were estimated spectrophotometrically using commercial diagnostic kits (Jiancheng Bioengineering Institute, Nanjing, China; Chen et al, 2011). Each sample was analyzed in triplicate.…”

“…The thermal cycle was as follows: 30 s at 958C for one cycle, 5 s at 958C and 34 s at 608C for 40 cycles. The mRNA expression of b-actin was used as an internal control (Chen et al, 2011), which was not significantly different between the two experimental groups. The values were normalized against the mRNA expression of b-actin and calculated as the percentage of the control value.…”

This study investigated the effects of different levels of dietary L-arginine (L-Arg) supplementation on the abdominal fat pad, circulating lipids, hepatic fatty acid synthase (FAS) gene expression, gene expression related to fatty acid b-oxidation, and the performance of broiler chickens. We tested whether the dietary L-Arg levels affected the expression of genes related to lipid metabolism in order to reduce body fat deposition. A total of 192 broiler chickens (Cobb 500) aged 21 days with an average BW of 920 6 15 g were randomly assigned to four groups (six broilers per replicate and eight replicates per treatment). The control group was fed a basal diet, whereas the treatment groups were fed basal diets supplemented with 0.25%, 0.50%, or 1.00% L-Arg for 3 weeks. The average daily feed intake, average daily gain and feed : gain ratio were not affected by the dietary L-Arg levels. However, chickens supplemented with L-Arg had lower abdominal fat content, plasma triglyceride (TG), total cholesterol (TC) concentrations, hepatic FAS mRNA expression and increased heart carnitine palmitoyl transferase1 (CPT1) and 3-hydroxyacyl-CoA dehydrogenase (3HADH) mRNA expression. These findings suggest that the addition of 0.25% L-Arg may reduce the plasma TC concentration by decreasing hepatic 3-hydroxyl-3-methylglutaryl-CoA reductase mRNA expression. This may lower the plasma TG and abdominal fat content by suppressing hepatic FAS mRNA expression and enhancing CPT1 and 3HADH (genes related to fatty acid b-oxidation) mRNA expression in the hearts of broiler chickens.

“…The present study showed that transportation or CMH supplementation had no effect on dressing percentage, breast and thigh muscle yield, and abdominal fat of broilers, which is in accordance with some previous studies (Bianchi et al, 2005;Doctor and Poltowicz, 2009;Chen et al, 2011). Dadgar et al (2010) found that birdsexperienced a 3-to 4-h transport under higher temperature (20 < T ⩽ 30°C) showed a lower pHu and higher cooking loss in breast muscle than those transported under lower temperature (T⩽20°C).…”

A total of 320 male Arbor Acres broiler chickens (28 days old) were randomly allotted to one of the three experimental diets supplemented with 0 (160 birds), 600 (80 birds) or 1200 mg/kg (80 birds) creatine monohydrate (CMH) for 14 days. On the morning of 42 day, after an 8-h fast, the birds of CMH-free group were divided into two equal groups, and all birds of these four groups were transported according to the follow protocol: 0.75-h transport without CMH supplementation (as a lower stress control group), 3-h transport without CMH supplementation, 3-h transport with 600 or 1200 mg/kg CMH supplementation. Each treatment group was composed of 8 replicates with 10 birds each. The results showed that supplementation of CMH for 14 days before slaughter did not affect the overall growth performance and carcass traits of stressed broilers (P>0.05). A 3-h transport decreased plasma glucose concentration, elevated plasma corticosterone concentration, increased bird live weight loss, breakdown of muscle glycogen, as well as the accumulation of muscle lactate (P<0.05), which induced some detrimental changes to breast meat quality (lower ultimate pH and higher drip loss, P<0.05). Nevertheless, supplementation of 1200 mg/kg CMH reduced chicken weight loss, decreased the contents of lactate and glycolytic potential in pectoralis major of 3-h transported broilers (P<0.05), which is beneficial to maintain breast meat quality by reducing the drip loss (P<0.05). These findings suggest that the reduction of muscle glycolysis is probably the reason for maintainance of meat quality by supplementation of CMH in transported broilers.

“…Creatine plays a critical role in energy metabolism, and it is the only organic compound that is involved in protein metabolism and that participates in the muscular energy buffering system (Khajali & Wideman, 2010;Chen et al, 2011). Michiels et al (2012) reported that a diet supplemented with GAA (0.6 and 1.2 g/kg) markedly increased the creatine concentration in broiler breast meat.…”

The objective of this study was to evaluate the supplementation of guanidinoacetic acid (GAA) and L-arginine (L-Arg) as creatine precursors to vegetable diets on the carcass yield and meat quality of broilers subjected to two days of heat stress before slaughter. A total of 1260 broiler chicks were distributed according to a completely randomized design into four treatments with nine replicates of 35 birds each. The treatments consisted of: T1 -vegetable diet based on corn and soybean meal (control diet); T2 -control diet with the inclusion of meat meal (3%); T3 -control diet supplemented with GAA (0.08%); and T4 -control diet supplemented with L-Arg (0.8%). The birds were submitted to heat stress for two days before slaughter (from 42 to 44 days of age). The birds fed the diets supplemented with GAA or L-Arg presented heavier carcasses (p<0.0035), higher breast yield (p=0.0685), and lower of abdominal fat deposition (p=0.0508) than those fed the control diet and the control diet with meat meal. The cooking loss of the breast fillets of broilers fed the control diet supplemented with meat meal, GAA or L-Arg was lower (p<0.0068) compared with those fed the control diet. Thawing and pressure-driven breast fillet weight losses, and pH, luminosity, redness (a*value), and yellowness (b* value) values were not influenced by the treatments. When GAA is less expensive than commercially-available Arg, the dietary supplementation of GAA is more advantageous, based on the meat yield improvements observed in the present study.
