Lysine (Lys) and Methionine (Met) as two primary essential amino acids and precursors of carnitine biosynthesis are involved in most of economical traits function in domestic animals. We assessed the impact of dietary Lys and Met on the performance, lipid redistribution, intramuscular fat, carcass quality and especially phenotypic correlations among some studied parameters in broiler chickens. ...

the present study was carried out to investigate the effect of different levels of triticale with/ without enzyme cocktail (xylanase and β-glucanase) on performance of broiler chicks. five hundred day old male broiler chicks (ross 308), assigned to a factorial arrangement (5×2) with a completely randomized design with 5 replicates of 10 chicks each. the factors included 5 levels of triticale (0...

Abstract This investigation was aimed to evaluate the effects of Silybum marianum seed, Thymus vulgaris , and Rosmarinus officinalis powders their combination in alleviating risks aflatoxin B1 (AFB1) young broiler chicks. One-day-old Ross 308 male chickens were allocated 6 experimental groups from d 1 21. The dietary included: Negative control (NC) received basal diet, Positive (PC) containing ...

this experiment was performed to investigate the effects of propolis and chromium picolinate on performance and immune response of broiler chicken under heat stress conditions. treatments included different levels of propolis (500, 1000, and 1500 mg/kg) and chromium picolinate (1500 µg/ kg) along with a control group. a completely randomized design was taken into account with 4 replicates of 10...

The present study was carried out to evaluate the effect of different levels of dietary seed and extract of Harmal (Peganum harmala L.) on immunity of broiler chicks. A total of 350 one-day old broiler chicks (Ross 308) were randomly allocated to five dietary treatments with four replicates pen of 14 birds each. Dietary treatments consisted of control, 1 and 2 g/kg Harmal seed in diet, 100 and ...

the present study performed to examine canola meal on morphology of thyroid gland in broiler chicks. in this experiment 300 l-day-old unsexed ross broiler chicks assigned into 5 groups. the chicks were fed by five level of canola meal (0, 5, 10, 15 and 20%). after 42 days feeding four chicks from each pen killed and their thyroid glands removed and immediately were immersed in formaldehyde, bef...

Two hundred and fifty male 1-day-old broiler chicks (Ross 308) were used to investigate the effects of dietary supplementation of turmeric and cinnamon powders on meat quality and lipid peroxidation of broilers under heat stress condition. The five treatment groups were control (recommended temperature for Ross 308), heat stressed (32 ± 1 ˚C from 9:00 AM to 5:00 PM during finisher period) and h...

introduction & aim: the aim the present study is to examine the effects of boswellia serrata triana & planch on (immune response) performance and carcass characteristic in broiler chicks.  experimental: in this study, 360 one day old chicks (ross 308) were allocated to six treatments with four replicates in a completely randomized design for a six week period. treatments consisted of t...
