Energy is an important component of poultry feed and is derived principally from cereal grains. Unfortunately, all of the chemical energy is not available to the bird, and biological assays must be used to determine the digestible energy value of a cereal grain. The bioassay described uses four pens of six male broiler chicks, complete diets containing 80% of a test cereal grain (with or withou...

The chick quality in broiler production is a major factor that has direct impact on the profitability of both hatcheries and producers. In recent years, there been considerable interest correlations between quality, which measured by quantitative or qualitative methods, yield characteristics. This study aims to compare viability, performance traits, meat characteristics chickens classified into...

Organic Acids (BacterActive) spraying and dipping on hatching eggs were evaluated experimentally for their effect embryonic mortality, hatchability, chick quality, immunity, eggshell bacterial count. A total of 6300 broiler breeder (Ross-308) at age 58 weeks, collected divided to 7 treatments as follows: (T1: General Control, T2: Dipping Water, T3: Spray T4: water, T5: organic acid, T6:spray Ac...

) leaves meal in rations on nutrient digestibility, hematological status and malondialdehyde levels broiler chicken blood. The study was conducted experimentally with a completely randomized design, which consisted of 5 treatments replications. treatment the use combination cassava tuber indigofera (70%+30%; CCI) ration, namely: T0 (0% CCI ration), T1 (5% T2 (10% T3 (15% ration) T4 (20% ration)...

Choosing the most suitable day-old chick (DOC) broiler chicken supplier is currently one of important issues that must be addressed. This because selecting can reduce amount spent on purchases and risk sick chickens being delivered by supplier. Another problem related to selection has been happening so far quality products are not following company standards or rejected products. The number pro...

This study investigated the teratogenicity of ethanol in several different strains of chickens. The chick embryo provides a useful model for studying the fetal alcohol syndrome. Two broad classifications of chicks, each containing many strains, are commercially available for use: broilers and layers. Teratogenicity of ethanol in broilers and layers was studied by examining three different param...

The present paper reports the propagation and partial characterization of calici-like virus particles previously observed in gut homogenates obtained from stunted broiler chicks. Radiolabelling experiments with [3H]uridine showed that the virus possesses an RNA genome and that it can replicate in primary chick embryo fibroblasts in the presence of actinomycin D. In vivo studies showed that the ...

One of the key stimulators of intestinal development in the chick is physical exposure to feed, while feed withholding delays the onset of gut development. A delay of 24-72 hours in onset of feeding is quite common in the poultry industry due to variation in hatching time and hatchery treatments. As intestinal development occurs in concert with the development of the gut associated lymphoid tis...

We evaluated the effect of a Lactobacillus-based probiotic culture (FM-B11) for reduction of Salmonella Enteritidis in neonatal broiler chicks. In all experiments, chicks were challenged with approximately 10(4) cfu of Salmonella Enteritidis upon arrival at our laboratory, and the treatments were administered 1 h postchallenge. Cecal tonsil samples were obtained 24 h posttreatment and enriched ...

A long history of toxicological problems has been associated with chlorinated aromatic compounds. Schulz (1) has given the clinical picture and an account of many episodes recorded since the initial description of chloroacne by Herxheimer in 1899. In addition to the history of human hazards, agriculture has been concerned with several episodes in which animal feeds were contaminated. Considerab...
