a total of 448 ross 308 seven-day old male broiler chicks were assigned to seven treatments with four replicates, each containing 16 chicks, to determine effects of physical sizes and rate of dietary inclusion of clinoptilolite. the chicks fed diet containing clinoptilolite at 1.5% and particle size of 0.4-0.8 mm showed significantly higher body weight gain than the control group that did not r...

Background: Nutrient restriction is a common strategy to prevent metabolic disorders in fast growing broiler chickens, but limited information available regarding the impact of diets with low protein and energy on leg abnormalities. Objective: Two experiments were conducted evaluate effect varying crude (CP) metabolizable (ME) levels gastrocnemius tendon (GTeBS) tibia breaking strength (TiBS), ...

the present study was carried out to examine the effects of a vitamin premix (vp) reduction or withdrawal from finisher diet (29-43 days) on performance, immuno-competence, and characteristics of leg bones and meat lipid oxidation of chickens fed on corn-soybean meal based diet. a total of 900 male broiler chickens (ross 308) were allocated to five treatment groups (0, 33%, 66%, 100% and 133% v...

This experiment was carried out to investigate the effect of feeding different levels of luffa aegyptiaca extracts (LAP) on the growth performance of broiler chicken fed corn-soya meal diet. The study was carried out between January to March, 2019. A total of two hundred day old broiler chicks of mixed sex (Ross 308) were allocated into four treatment groups, each group was further divided into...

this study was conducted to determine the effects of adding ethanol extract of propolis (eep) and cumin essential oil (ceo) to diets of broiler chicks on the performance, blood parameters, immune response and carcass traits. a total of 240 day-old ross-308 broiler chicks were randomly allocated to four treatments with six replicates and 10 birds in each replicate in a completely randomized desi...

Background & Aim: Aflatoxin (AF) is the most important fungus that contaminates food and feed and can enter the food chain of humans. The aim of this study was to investigate the ability of thistle seeds (silybum marianum L.) to reduce the adverse effects of aflatoxin B1 (AFB1) on the immune system, variables related to the intestine, appearance and mortality of t...

A total of 96 one day-old Ross 308 chickens, divided, in to 12 groups (3 treatment and 4 replicate pens per treatment and 8 chickens per pens) in a same environmental conditions. Group A, consider as control group and group B and C considers as experimental groups. From first day, vitamin A premix was added to group B diets and complex of vitamin E premix and selenium was added to group C diets...

an experiment was conducted to evaluate the effects of dietary crude protein (cp) and lysine levels on performance and nitrogen excretion in broiler chickens. four hundred twenty 7-day old chickens from ross 308 strain were randomly allotted to 6 dietary treatments with 5 replicates of 14 chicks each (7 male and 7 female chicks). the cp levels were 17, 18, and 20 percent and lysine levels were ...
