Effects of dietary protein source and level on intestinal populations of Clostridium perfringens in broiler chickens.
Two experiments were conducted to examine the effect of the level of dietary crude protein and protein source on intestinal populations of Clostridium perfringens in broilers. In experiment 1, 6 groups of 12 birds were fed diets containing 230,315 or 400 g/kg crude protein with soy protein concentrate (SPC) or low-temperature-dried fishmeal as the major protein sources in a 2 x 3 factorial arra...
متن کاملEvaluation of the efficacy of yeast extract in reducing intestinal Clostridium perfringens levels in broiler chickens.
The etiological agent of necrotic enteritis is Clostridium perfringens. Traditionally, necrotic enteritis is controlled with in-feed antibiotics. However, increasing consumer demand for drug-free poultry has fostered the search for nonantibiotic alternatives. Yeast extract contain nucleotides that are immunomodulatory and also essential for cellular functions. An experiment was conducted to eva...
متن کاملShort communication PREVALENCE OF CLOSTRIDIUM PERFRINGENS TYPE A ISOLATES IN DIFFERENT TISSUES OF BROILER CHICKENS
Clostridium perfringens (C. perfringens) is an important pathogen in both human and veterinary medicine. Necrotic enteritis is the most severe clinical bacterial enteric disease of poultry induced by C. perfringens. Study was done on 100 broiler chickens (400 different tissues of chickens) in Southwest Iran. C. perfringens was isolated from different tissues of chickens (meats, liver, gizzard a...
متن کاملThe response of broiler chickens and turkey poults to steam-pelleted diets supplemented with fat or carbohydrates.
The responses of growth and feed efficiency to pelleted feed was investigated in 4- to 7-wk-old broiler chickens, and in 8- to 12- and 16- to 20-wk-old turkeys. In all cases, the growth and feed efficiency responses were linear within the ranges of dietary energy tested. When energy was added by carbohydrate supplementation, weight gain and feed efficiency responses were parallel for both mash ...
متن کاملImmunization of broiler chickens against Clostridium perfringens-induced necrotic enteritis.
Necrotic enteritis (NE) in broiler chickens is caused by Clostridium perfringens. Currently, no vaccine against NE is available and immunity to NE is not well characterized. Our previous studies showed that immunity to NE followed oral infection by virulent rather than avirulent C. perfringens strains and identified immunogenic secreted proteins apparently uniquely produced by virulent C. perfr...
