“…The feed efficiency was significantly better in high energy than other energy levels which coincide with the observation of Corduk et al (2007). High energy diets to broilers help maximize energy intake and this higher energy intake maximizes the growth rate (Leeson and Summers 2001).…”

The objective of this experiment was to study the effect of dietary supplementation of Coenzyme Q10 on broiler growth rate, carcass characteristics and cost of production. A biological trial was carried out with 270 broiler chicks fed with coenzyme Q10 at 0, 20 and 40 mg/kg of diet at each of the three energy levels. At the end of 42 days growth period the birds were sacrificed and the samples were analysed. Feed intake was comparable in all the energy and CoQ10 combinations, but higher body weight gain and better feed efficiency with less feed cost per kilogram weight gain was observed in high energy group supplemented with 20 mg of CoQ10/kg diet. The dressing percentages, weight of giblet, liver, spleen, abdominal fat, intestinal length were not significantly altered by CoQ10 supplementation. The heart weight, gizzard weight and ascites heart weight (AHI) were significantly decreased due to CoQ10 supplementation. Hence, birds fed with high energy diet supplemented with 20 mg CoQ10 per kg of diet had higher production performance.

“…Rosa et al (2007) reported that carcass chemical composition changes in different genetic groups; however, for commercial Ross 308 broilers there was reduced crude protein and increased lipid in carcass with increased dietary energy level in broilers. Others found no effect of dietary energy level on chemical composition of carcass muscle of broilers (Corduk et al 2007; Gómez-Rosales et al 2012). …”

Background Diets with increasing levels of energy were fed for 42 days to 200, 1-day old male broiler chickens to evaluate growth performance, carcass characteristics and chemical composition of meat. The study was performed in the subtropical area of northeastern Mexico. Treatments diets (T) for starter and finisher phases had apparent metabolizable energy (AME; kcal/kg) of: 2960 and 3040 (T1); 3000 and 3080 (T2); 3040 and 3120 (T3); 3080 and 3160 (T4), respectively. Within each of the growing phases the four treatment diets were formulated to contain similar levels of crude protein, amino acids, and other nutrients. In a completely randomized design, birds were allocated to the four treatments with five replicates (floor pens) of 10 birds each. The trial was divided in two phases (starter and finisher) of 21 days each (42 days total).ResultsWeight gain was not influenced by energy level; however, feed conversion efficiency was improved in the diets with 3040 and 3120 kcal/kg AME (T3; P < 0.05). There was no influence of treatment on total carcass weight or carcass cuts (P > 0.05). Meat from breast muscle had similar crude protein percentages among treatments; ether extract was higher in T1 than T4 (P < 0.05). The percentages of water, ether extract, ash and crude protein in thigh meat were not significantly different (P > 0.05) among treatments. ConclusionsFor this study carried out in a dry tropical area, the moderate increase in dietary energy concentration (diet with 3040 and 3120 kcal/kg AME, T3) enhanced feed conversion efficiency of broiler chickens.

“…It is cleared that when liver works healthy, the activity of these two enzymes in serum will reduce in broiler chickens (Corduk et al, 2007). It is reported that high fat diets could alter the related enzyme profile in serum and liver tissue (Ishii et al, 2010).…”

An experiment was conducted to evaluate the growth performance, carcass characteristics and blood metabolites of broiler chickens fed diets formulated on total or digestible amino acids (TAA or DAA) basis with bovine bile salts powder (BBSP) and different levels of soybean oil (SO). A total of two hundred and forty 1-day old chicks were randomly allocated to eight treatments with three replicates of 10 birds. The experiment was carried out in a completely randomized design with 2×2×2 factorial arrangement, including two levels of BBSP, two levels of SO and two methods of amino acids balance (TAA or DAA) in diets. The results showed that main effects of BBSP, SO and feed formulation procedures (TAA or DAA) had no effects on all growth performance parameters (P > 0.05). Carcass traits, except for thigh weight, were not influenced by all dietary treatments (P > 0.05). The birds fed diets with BBSP had a greater thigh weight than the other group. The results of blood biochemical metabolites indicated that serum triglyceride was affected by amino acid formulation method (P < 0.05). In contrast, the other serum metabolites did not alter by dietary treatments (P > 0.05). The results indicated that liver enzymes activities including alanine aminotransferase (ALT) and aspartate aminotransferase (AST) were not influenced by dietary BBSP and SO (P > 0.05). However, AST activity was affected by amino acids formulation procedure (P < 0.05). In conclusion, the addition of bile salts (BBSP), different inclusion rate of SO and amino acids balance method (DAA or TAA) in broiler diets had no negative effects on all growth performance and carcass traits.
