“…Vitamin E supplementation of the diet at a dose of 125 ppm was more applicable in increasing the calcium content of tibia as compared to that of 250 ppm, because the supplementation at the two levels did not show significant differences. Lohakare et al (2005) showed that calcium retention was higher when vitamin E was added at higher levels.…”

The purpose of this study was to determine the effect of zinc (Zn) and vitamin E supplementations on apparent nutrient digestibility, carcass traits, and mineral availability of broiler in tropical environment. The experiment was arranged in a 3 x 3 factorial design with 4 replications in each treatment (10 birds each). The dietary treatments were the combination of doses of zinc (A1: 0 ppm, A2: 40 ppm, A3: 80 ppm) and vitamin E (B1: 0 ppm, B2: 125 ppm, B3: 250 ppm) supplementations. The variables observed were apparent nutrient digestibilities (apparent crude protein digestibility and apparent ether extract digestibility), carcass traits (final weight, the percentage of carcass weight, breast weight, thigh weight, wings weight, and back weight), meat bone ratio and mineral availability in the tibia (calcium [Ca], phosphorus [P], and zinc [Zn]). The results showed that apparent nutrient digestibility, carcass traits (the percentages of carcass, breast, thighs, wings, and back), meat bone ratio were not significantly influenced by the supplementation of zinc or vitamin E. The supplementation of 80 ppm of Zn and 0 ppm of vitamin E significantly (P<0.05) increased final weight of broiler. Supplementation of zinc alone and vitamin E alone in the diet significantly (P<0.05) increased calcium content of the tibia. In conclusion, supplementation of 80 ppm of Zn increased calcium content compared to control, but did not affect final weight and ether-extract digestibility. Supplementation of vitamin E at a dose of 125 ppm could increase calcium content of the tibia compared to control.

“…It is well known that dietary amino acids have important effects on carcass characteristics of broilers (Dozier et al, 2000;Gong et al, 2005;Lohakare, et al, 2005). Moran and Bilgili (1990) and Acar et al (1991) reported live body weight and chilled carcass were not affected by dietary lysine, whereas Tesseraud et al (1999Tesseraud et al ( , 2001 stated that lysine deficiency reduced the performance as well as muscle weights, and breast meat weight decreased when feeding low density of dietary lysine to chicks at 50 d of age (Kidd et al, 1998).…”

An experiment was performed to evaluate the effects of dietary metabolizable energy (ME) and lysine on carcass characteristics and meat quality in Arbor Acres (AA) broilers from 1 to 56 days of age. A total of 2,970 1-d-old male broiler chicks were randomly allocated to nine dietary treatments (three ME levels in combination with three lysine levels), and dietary ME and lysine concentrations were formulated by varying corn, soybean meal, tallow, and L-lysine sulfate concentrations. Live body weight (BW), carcass weight (CW), dressing percent, breast muscle weight (BMW), yield of breast muscle, muscle color (CIE L*, a*, and b*), pH values 45 min and 24 h postmortem (pH 45 , and pH 24 ), meat shear force value (SFV), and water loss rate (WLR) were evaluated. Results showed that live body weight and dressing percent increased (p<0.05) as dietary energy increased. Higher dietary lysine content improved breast muscle weight. Neither carcass weight nor yield of breast muscle was affected by dietary energy or lysine content. Higher ME increased the b* value (p = 0.067) and pH 24 value (p<0.05), whereas it decreased SFV (p<0.05) and WLR (p = 0.06). Only water loss rate was influenced (p<0.01) by dietary lysine, which was higher in broilers from the high lysine diet as compared to those from medium or low lysine diets. The pH 45 value and L* value of breast muscle were not affected by ME or lysine. Significant interaction of dietary ME and lysine was found on a* value of breast muscle. These results indicated that dietary ME and lysine had important effects on breast muscle growth and meat quality, however their effects were different. Different concentrations of dietary ME and lysine might be considered to improve meat quality.

“…Diets rich in vitamin E and zinc have been shown to reduce the catabolic response induced by immune stimulation and may be effective in promoting growth (Rymer and Givens 2005). Lohakare et al (2004) in an experiment conducted on commercial broiler farm of 3,630 Ross female broiler chicks observed significant (p<0.0001) increase in body weight gain in birds fed higher levels of vitamin E. Chae et al (2005) also reported an improvement in weight gain in commercial broilers supplemented with different levels of vitamin E without affecting the feed efficiency. El-Dein et al (2013) reported better values of Feed conversion ratio (FCR) among chicken supplemented with vitamin E compared to control.…”

The study investigated the effect of supplementation of Vitamin E, Zn and Cr on growth performance and hematological characteristics of broiler chickens. The 240 day old Cobb 400 chicks were randomly distributed in eight groups consisting of 30 chicks in each. These chicks were kept on deep litter houses comprising of wood shavings. The supplementation of Vitamin E, zinc and chromium either individually or in combination improved the feed conversion ratio and body weight gain in broiler chicks. The body weight of broiler chickens at different age from day old to the 6 th week were significantly different among treatments. The highest body weight was recorded in T8 groups. Heamoglobin, red blood corpuscles and white blood cells levels increased whereas heterophil: lymphocyte ratio statistically decreased with vitamin E, zinc or chromium supplemented groups either individually or in combinations.
