An experiment was conducted to evaluate the effects of phytase supplementation on the growth performance, nutrients utilization and bone mineralization in broiler chickens. Day-old broiler chicks (n=480) were equally devided into eight treatment groups and fed maize or wheat based isocaloric, isonitrogenous and isocalcium diets having two non phytate phosphorus (NPP) concentrations (0.50% and 0...
Background: Heat stress is one of the most important environmental stressors challenging poultry production worldwide. Understanding and controlling environmental stressors is crucial for successful poultry production. OBJECTIVES: The aim of the present study was to investigate the effects of melatonin supplementation and darkness regime on reducing the negative effects of heat stress in broile...
torque teno virus (ttv) is prevalent worldwide and has been extensively studied in human and some wild and domestic animals. as the studies on ttv in chickens was rare and there was no information about the infection of domestic village chickens with ttv and also structural resemblance of this virus to chicken anemia virus, the frequency of the infection in domestic village chickens in differen...
background: this study aims to evaluate the efficacy of silybum marianum seeds (smss) on blood biochemical profile of broiler chickens contaminated with aflatoxin b1 (afb1). methods: combinations of three levels of afb1 (0, 250 and 500 ppb) with three levels of smss (0, 0.5, and 1.0 %) were incorporated into the basal diet (corn and soybean meal). the effect of nine experimental treatments was...
Low-fibre sunflower residue (SFR) included in the diet is a viable option for improving production in smallholder-owned poultry. Four hundred day-old broiler chicks (200 hybrid + 200 village chicks) were given broiler starter (1-28 days) and a low-fibre sunflower residue diet (29-84 days). On day 29 the chicks were randomly allocated to four treatments (2 types of chicks, 2 systems of housing):...
Effects of extrusion of rice bran on performance and phosphorous bioavailability in broiler chickens
BACKGROUND Rice bran is a by-product of the rice-milling process, which remains largely underutilized; however, efficient processing treatments may improve its feeding value for chickens. This is of great economic and environmental importance, as this can lower the production costs, and offer an opportunity for valorization of a low-quality agricultural by-product, to a high-value feed source. ...
In an attempt to determine the seroprevalence of avian leukosis virus (ALV) in exotic broiler chickens and Nigerian local chickens in Zaria, Nigeria, a total of 600 sera (300 from exotic broiler chickens and 300 from Nigerian local chickens), obtained from the live bird market in Zaria, Nigeria, were tested for ALV p27 antigen by the antigen capture enzyme linked immunosorbent assay (ac-ELISA) ...
