in this research the effect of feeding wheat/ barley based diets supplemented with three commercial enzymes containing xylanase and ?-glucanase activities and including matrix value their on performance and gastrointestinal tract size of broiler chicks was investigated. a total of 260-day-old male broiler chicks (ross 308) were allocated to 5 treatment groups, with 4 replicates per treatment an...

Soybean oil (SO), rapeseed oil (RO), or two commercial fat products (FPl, FP2) were incorporated at 3.5% levels into four different corn-soybean meal mash broiler diets. Each of the four diets was fed to five replicates (pens) of broiler chickens for 42 d. After slaughtering the birds, samples of the abdominal fat, subcutaneous fat, and fat extracted from the thigh and the breast portion were c...

A five-week study was conducted to determine the effect of feeding varying levels S. cerevisiae on carcass and organ characteristics finishing broilers. One hundred twenty 4-weeks old broilers cobb strain were randomly assigned four treatments (T1 = 0.6 g Saccharomyces (SC) kg–1 diet; T2 0.8 SC T3 1.0 diet T4 0.0 diet) with 30 birds per treatment replicated twice 15 replicate in a completely ra...

the study was carried out to evaluate the effects of complete replacement of maize with two varieties of guinea corn and two varieties of millets on the growth performance and nutrient retention in broiler chickens. five isonitrogenous and isocaloric diets for the broiler starter (23.5% cp; 2800 kcal/me) and finisher (21.5% cp; 2900 kcal/me) phases were formulated. diet 1 consisted on a maize b...

this experiment was designed to evaluate the effect of dietary caspian kilka fish oil on breast meat fatty acid (fa) profile and as well as sensory acceptability of breast meat. fish oil supplementation was added to provide four graded levels (0, 1, 2, and 3% fish oil) in place of vegetable oil for supporting 3% oil in the diet during the period of breeding. these four diets were allocated to o...

In this research a 100 day long treatment period was considered to unmask the probable adverse effects of long-term induced hyperthyroidism on histomorphometrical attributes of the oviduct in broiler breeder hens. A total of seventy 47-week-old Cobb 500 breeder hens were randomly allotted to two treatment groups (5 replicates of 7 hens each). Thyroxine (T4) was orally administered to the hypert...

This experiment was undertaken to evaluate the effect of dietary level of artichoke (Cynara scolymus) on growth performance and immune response of broilers under heat stress (HS). Two hundred forty day-old broiler chicks (Ross, 308) were randomly assigned to one of four dietary treatments with four replicate pens per treatment (15 birds per pen) in a completely randomized design with a 2 × 4 fa...

Bacteriophages isolated from free-range chickens were tested as a therapeutic agent for reducing the concentration of Salmonella enterica serovar Enteritidis phage type 4 (S. Enteritidis PT4) in caeca of broilers. One-day-old broilers infected with S. Enteritidis PT4 by a seeder bird method were orally treated on the seventh day of age with a mixture of 10(11) plaque-forming units of each of th...

This study was performed with growing chickens (14 to 56 days of age) to evaluate the effects of feeding a barley-based diet. The treatments were maize diet (1) as a control, barley diet with (4) or without (2) the commercial enzyme β-glucanase, barley treated with rumen fluid without protozoa (3) and hulless barley (5). The effects of treatments were investigated in a 42-day trial using 360 se...

Background & Aim: Medicinal plants is very potential to be used as a supplementary feed as well as feed additive in broilers.This experiment was conducted to investigate the effects of milk thistle (MT) and thyme seeds (TS) on the performance in broilers. Experimental: In this study, 160 one-day-old (Ross 308) male broiler chicks were divided randomly into four major groups with 4 replicates b...
