background: heat stress declines the performance through physiologic changes of the poultry. objectives: this experiment was conducted to evaluate the effects of different levels of l-carnitine on performance, carcass characteristics and some blood parameters of broiler chickens fed with high fat diets under heat stress. methods: two hundred one-day-old broiler chicks (ross 308) were used in a ...

This study was conducted to investigate the effects of L-carnitine and different levels of animal fat on performance, carcass characteristics and some blood parameters of broiler chickens. Two hundred one-day old male broiler chicks were allotted to5 treatments in 4 replicates and 10 birds in each replicate. Dietary treatments consisted of: 1) diet with 5% vegetable oil (T1), 2) diet with 5% ve...

The aim of this study was to investigate whether a L-carnitine, choline, artichoke leaf extract and sorbitol combination (Hepabial Carnitine ® ) supplied by drinking water would influence broiler performance under stress induced by high stocking density (18 chicks per square meter). A total of 270 1-dayold male broiler chicks (Avian Farm) were randomly distributed into 2 groups (Hepabial Carnit...

Study was carried out to find out the effect of L-carnitine supplementation on carcass characteristics in Venncobb broiler chicks fed with diet containing animal fat. Eighty day old commercial broiler chicks were randomly allotted to two treatment groups (T1 and T2) with four replicates of ten chicks each. The birds were fed with standard broiler chicken ration (BIS, 1992) containing 5% animal ...

An experiment was conducted in order to study the effect of 3 levels of fat (1, 3, 5%), and 2 levels of L-carnitine (0, 250 mg/kg) on 360 male Ross broiler chicks in a factorial arrangement (2×3) with completely randomized design with 6 treatments, 4 replicates, and 15 chicks in each replicates. All diets were isocaloric and isonitrogenous and were fed to chicks from 1 to 42 days of ages. Durin...

Effects of excess of dietary methionine (6.5 and 8.5 g kgG1 diet) and lysine (13.5 and 15.5 g kgG1 diet) on performance, blood lipid profile and litter quality of broiler chickens fed corn-soybean meal based diet with or without supplementation of L-carnitine with two levels (175 and 350 mg kgG1 diet) were investigated. Two hundred forty one day old chicks (Cobb) of mixed sex were housed in pen...
