the current study was conducted to evaluate effects of sequential or wet feeding programs subsequent to and early meal feeding regime on performance, carcass characteristics and humoral immunity in broiler chicks. 192 ross 308 chicks (seven-day old) were allocated to four treatments at four replicates (12 chicks per plot) based on a completely randomized design. treatments were included: contro...

the effect of silver nanoparticles as additive on broiler performance was investigated through employed of 312 day-old broiler chiks (arbor-acre plus) in a completely randomized design with 6 treatment diets each in 4 replicates. corn- soy based diets were formulated for starter, grower and finisher according to nrc (1994) recommendations. the silver nanoparticle solutions (2000 ppm) were added...

This study was conducted to evaluate the effects of dietary supplement-ation of rosemary essential oils (REO) and zinc (as zinc sulfate) on performance, egg quality traits, and some serum biochemical metabolites of laying hens. A total of 144 44-weeks-old Lohmann LSL-Lite laying hens were randomly allocated into four treatments, each comprising six replicates of six birds. The first group was s...

an experiment was conducted to determine the dietary digestible lysine requirement of male and female broiler chickens (arian) during the period from 6 to 21 days post-hatching. an amino acid-fortified basal diet containing corn and soybean meal as intact protein sources provided 20 % cp, and 3200 kcal amen / kg. in this experiment 150 male and 150 female chicks were allocated on the basis of b...

An experiment was conducted to determine the effect of bird age, diet (feeds formulated with 69.5% corn, 69.7% milo, or 73.6% wheat), and feed withdrawal times (0 or 8 hours) on color (CIE L*, lightness; a*, redness; and b*, yellowness) of raw broiler breast fillets. Broilers were placed on diets at 28 d of age. Replicate groups of 24 birds (eight each from different diet and four each either f...

The present study was undertaken to study the combined effect of Aflatoxin and Ochratoxin A on liver enzymes of broilers and the amelioration of the effects using adsorbents. Aflatoxin and ochratoxin A were mixed with the broiler diet to attain a concentration of 1 ppm and 2 ppm respectively. Activated charcoal at 0.4% and lyophilized yeast culture at 0.2% level were used as adsorbents for test...

control of poultry feed microbial contamination could reduce carcass contamination at processing plants and resultin improvement of public health. in this study the effects of commercial blend of organic acids (salkil® and formycine®), formalin 37% and formaldehyde gas on morphology of intestinal mucosa and gut microflora in broilers were investigated. three hundreds 1-d-old chicks (ross 308) w...
