The present work was conducted to examine the effects of dietary crude protein (CP) levels (18, 21 and 24%) on growth performance (Initial and final body weight, daily body weight gain, feed consumption, feed conversion and protein efficiency ratio) during 2-9 weeks of age and certain body measurements (body height, tibiotarsus length and tibiotarsus girth) at 9 weeks of age. A total of 30 Afri...

The effects of water supplementation of bee venom (BV) on performance, antioxidant activity, and liver function in Arbor Acres broiler chickens were investigated. Hence, 3 experimental treatment groups (control, 0.5 mg/L of BV, and 1 mg/L of BV) were allocated to 3 replicates of 5,000 one-day-old chicks each. The control group was kept on tap water, whereas the other 2 groups were supplied wate...

in order to study the effect of different levels of β-mannanase enzyme on the performance, blood parameters and carcass characteristics of broiler chicks (arbor acres), an experiment was conducted with 240 checks (44.6 grams average weight) under a completely randomized design with 4 treatments and 5 replications and 12 checks per each replicate. β-mannanase enzyme with the levels of zero (t1 c...

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...

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...

A study was conducted to see the effect of dietary incorporation of alkali (1.5% NaOH, w/w) processed solvent extracted karanj cake (SKC) supplemented with methionine on growth performance, humoral immune response and carcass characteristics of broiler chickens from 0 to 8 weeks of age. One hundred and twenty, dayold broiler chicks were wing banded, vaccinated against Marek’s disease and distri...

this experiment was carried out for a period of 4 weeks with 240 day old straight- run broiler (cobb-500) chicks to investigate the effects of administering electrolytes in drinking water on the productive performance (live weight, body weight gain, feed consumption, feed conversion and water consumption) and to determine the economic impact of using electrolytes. the chicks were randomly distr...

this experiment was conducted to evaluate the effect of physical feed form on performance and nutritional behaviors in broilers. this experiment was done in a completely randomized design with several observational with 3 treatments and 5 replicate. dietary treatments included off of pellet form, crumble and mash form with similar components for 3 periods starter (0-10 days), grower (11-24 days...
