s of papers 47 tered via water, in preventing necrotic enteritis (NE) in broilers and reducing fecal bacteria. The NE challenge model included: 200,000 Eimeria acervulina oocysts/bird 5d and Clostridium perfringens (CP) 7d posthatch. Healthy, newly-hatched broiler male chicks (Ross x Cobb commercial source) were randomly placed into wire floor cages. Treatments included positive non-infected co...

Ascites syndrome is indicating the abnormal accumulation of non-inflammatory fluid in abdominal space. Hypoxia is the most important cause of pulmonary hyper blood pressure in broiler poultry. The aim of this study is a comparative survey of ascites syndrome incidence rate in Ross, Arbor-Acrese and Cobb strains of broiler chickens. For this purpose, 150 broiler male chicks of Ross, Cobb, and Ar...

A 2×2 factorial experiment was conducted to study the effect of dietary calcium and non-phytate phosphorus (nPP) imbalance on calbindin and NaPi-IIb mRNA levels in the small intestine and tibia parameters of broiler chicks. One hundred and forty four 1-d-old Arbor Acres male broiler chicks were divided into four treatments consisted of six replicates with six chicks each. The two dietary calciu...

An experiment was conducted to evaluate different levels of “new generation” distillers dried grains with solubles (DDGS) in broiler diets throughout a 49 d growing period, based a standardized nutrient matrix derived from a composite of literature values. Diets were formulated based on digestible amino acid content to typical U.S. poultry industry standards to contain 0, 5, 10, 15, 20, or 25% ...

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...

Chitin is the most abundant natural biopolymer that can be converted to chitosan, which has various biomedical applications. This study was conducted to investigate the antioxidant activity of chitosan extracted from shrimp shells on body weight of broiler chickens. The study comprised three experiments. In experiment 1, shrimp (Penaeus merguiensis) shells were demineralized using HCL (1N), dep...

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...

This research project was conducted to evaluate bioavailability and chemical properties of different zinc sources in broiler chickens when fed by practical diets. For that, 312 day-old male Ross 308 broiler chicks were fed from 8-28 day to estimate the biological availability of four zinc sources. Chicks were allocated randomly to 13 experimental diets in a 3 × 4 factorial design. Diets include...

The study determined the effects of garlic, ginger and their mixtures on the growth, serum lipids, haematological indices, carcass and organs of broilers. Garlic and ginger were each added to broiler diets at 1, 1.5 and 2%. Four mixtures of garlic and ginger were also formulated. Control diet did not contain any test ingredient. The results showed that garlic, ginger and mixtures contained 7.41...
