1. The effects of Concanavalin A (Con A) on enzymes from the intestinal brush border were studied using membrane vesicles (BBMV) prepared from 3- and 6-week-old broiler chickens. 2. Maltase, sucrase, phytase, alkaline phosphatase and leucine aminopeptidase activities were assayed in BBMV in the absence (T0) or presence (T1) of Con A, or in the presence of casein (T2). Disaccharidase specific ac...

Two experiments were conducted to determine: first, the best time of excreta collection after force feeding of broilers to yield the maximal amount of excreta, and second, nitrogen-corrected true metabolizable energy contents of some poultry feedstuffs including yellow corn, soybean meal, corn gluten meal, canola meal and poultry by-product meal by a new precision-fed chick assay using 3-week-o...

Background: This study was conducted to determine the effect of particles size starter diet on growth performance broiler chickens. Methods: A total 384 Arbor Acres chicks were usedin a completely randomized design with three treatments and four replicates 32 birds each.Birds fed diets 3 sizes (T1: 1.0 mm; T2: 0.8 T3: 0.7 mm) during first week life. At 7 d, same offered in crumbled form until 1...

In the present experiment, 320 one day old Ross 308 broiler chickens were used completely randomized design with 4 treatments, 4 replicates, and each replicate contained 20 broiler chickens. Experimental treatments include control, 0.5, 1, and 2% of Thymolina powder in chickens’ diet. Thymolina is an antibacterial powder drug which is made by composing 4 medicinal plants. A significant differen...

To asses the effect of turmeric (Curcuma longa) supplementation on antioxidants and immunity of broiler chickens, seventy five run day old coloured synthetic broiler chicks were randomly divided into 3 groups (25 chicks per each) of mixed sex. Group I served as control (without any supplementation), whereas birds in groups II and III were supplemented with 0.5% and 1.0% Curcuma longa powder res...

The present study was carried out to determine the effects of using dried rose dreg (DRD) as an alternative litter material for broiler performance and microbiological characteristics of litter. A total of 225 day-old broiler chicks was raised on pine wood shavings (PS), DRD and PS+DRD until 42 days. The effects of litter material on broiler performance and FCR did not differ. At 42 days the ef...

Recent studies have suggested the utilization of maggots as a feed supplement forenhanced broiler performance. Maggots, which are a major dietary source of protein, appear during the biodegradation of chicken droppings using house flies. The objective ofthe present study was to investigate the effect of maggot supplementation on the meat quality and growth performance of broiler chickens. A tot...

A 4-week feeding trial with 120 day-old broiler (Hubbard) chicks was conducted to determine the efficacy of microbial phytase (Natuphos

Selenium (Se) is an essential trace mineral that plays important role in physiological processes by regulating the antioxidant defense system and enhancing immunity. Chromium involved carbohydrate lipid metabolism also a maintaining normal insulin function. Based on these advantages, we hypothesized addition of selenomethionine (SeMet) organic chromium (OC) to broiler diets would increase selen...

This study was conducted to investigate the toxic effects of aflatoxin B₁ (AFB₁) and evaluate the effects of sporoderm-broken spores of Ganoderma lucidum (SSGL) in relieving aflatoxicosis in broilers. A total of 300 one-day-old male Arbor Acre broiler chickens were randomly divided into four dietary treatments; the treatment diets were: Control (a basal diet containing normal peanut meal); AFB₁...
