In this study, the effect of xylanase and cellulase supplementation in palm kernel meal (PKM) based diet on growth performance, volatile fatty acids (VFAs) and the caecal bacterial populations of broiler chickens were investigated. Seventy five day old male Cobb broiler chicks were randomly allocated to three dietary treatment groups receiving T1 (20% PKM-based diet without enzyme), T2 (20% PKM...

BACKGROUND Lighting is used during conventional broiler grow-out to modify bird behaviour to reach the goals of production and improve bird welfare. The protocols for lighting intensity vary. In a field study, we evaluated if the lighting practices impact the burden of Salmonella in broiler flocks. METHODS Conventional grow-out flocks reared in the states of Alabama, Mississippi and Texas, US...

Mycotoxins affect poultry production by being present in the feed and directly causing a negative impact on bird performance. Carry-over rates of mycotoxins in animal products are, in general, small (except for aflatoxins in milk and eggs) therefore representing a small source of mycotoxins for humans. Mycotoxins present directly in human food represent a much higher risk. The contamination of ...

In most areas of the world, broiler chickens are raised in floor systems, but cage confinement is becoming more common. The welfare of broiler chickens in cages is affected by movement restriction, poor bone strength due to lack of exercise, and prevention of key behavioral patterns such as dustbathing and ground scratching. Cages for broiler chickens also have a long history of causing skin an...

An experiment was conducted to determine the effect of supplementing various concentrations (0, 100, 200, 300, or 400 μg/kg diet) of organic Se on growth performance, carcass traits, oxidative stress, and immune responses in commercial broiler chickens reared in open-sided poultry house under tropical climatic conditions. Each diet was fed ad libitum to eight replicates consisting of six birds ...

OBJECTIVE Considerable controversy persists regarding the use of human antibiotics to promote growth in animals raised for food. The authors examined the economic effect of removing antibiotics used for growth promotion in commercial broiler chickens. METHODS The authors utilized data published by the Perdue company, the fourth largest poultry producer in the United States, in which a non-ran...

OBJECTIVES The purpose of this study was to characterize sets of extended-spectrum β-lactamases (ESBL)-producing Enterobacteriaceae collected longitudinally from different flocks of broiler breeders, meconium of 1-day-old broilers from theses breeder flocks, as well as from these broiler flocks before slaughter. METHODS Five sets of ESBL-producing Escherichia coli were studied by multi-locus ...

Tekeli, A., H. RuSTu kuTlu and l. Celik, 2014. Dietary inclusion of grape seed oil in functional broiler meat production. Bulg. J. Agric. Sci., 20: 924-932 The purpose of this study is to explore the effects of grape seed oil on growth performance, some blood parameters and fatty acid composition in broiler meat. in order to formulate isocaloric ratios, the corresponding amounts of soy oil were...

potential for decreasing the amount of symbiotic N2 fixation. In contrast, Lory et al. (1992) reported that Although most of the N required by soybean [Glycine max (L.) topdressed manure addition to alfalfa (Medicago sativa L.) Merr.] is provided through the process of symbiotic N2 fixation, supplemental N using broiler litter may boost soybean grain yields. The efdid not affect N2 fixation. Ga...
