Animal welfare has generated concerns from both domestic and global market sectors. In growout, stocking density has been regarded as an area of interest for food retailers and wholesalers with welfare audits. This study examined four stocking densities on responses of male broilers during a 49d production cycle. Two trials were conducted and results were pooled. In each trial, 1,488 male chick...
An experiment was carried out to investigate the effects of different levels of energy (2700, 2900 and 3100 kcal/kg) and protein (13, 14.5 and 16 %) on laying performance of Fars native hens during the first phase of production. Two hundred and sixteen 25-week-old native pullets were put into fifty four groups of similar live weight (994 ± 169 gr) of four chickens, which were randomly allocated...

Deoxynivalenol (DON), a mycotoxin produced by some Fusarium species, is a frequent contaminant of cereal. In the present study, 24 weanling piglets received either control feed or feed naturally contaminated with DON (2.8 mg/kg) for four weeks. Consumption of contaminated feed significantly reduced the animal weight gain during the first week of the experiment, but had a moderate effect on cult...
Effect of supplemental phytase on phosphorus and protein utilization and performance of broiler chickens fed on eight different wheat varieties were evaluated. The phytate contents of wheat varieties were determined. In a completely randomized design with a 8*3 factorial arrangement, 384 day-old commercial male brioler chicks (HubbardPeterson) were divided into 96 groups, four chicks per group...

feed resources availability at cheap and affordable prices for livestock consumption are major factors determining capability of livestock production to supply products for increasing urban and cities consumers in nigeria. to take advantages of the high demand in urban areas, livestock producers on extensive pastoralism are moving closer to cities and urban communities such as abuja the nigeria...
Materials and methods: Ninety-six crossbred pigs 17 to 20 days old were randomly assigned to six experimental diets. A nonmedicated basal diet was supplemented with carbadox (55.12 g per tonne), copper sulfate (192.40 g copper per tonne), zinc oxide (2712.68 g zinc per tonne), or the probiotic feed additive BioPlus2B (Chr Hansen Inc, Milwaukee, Wisconsin; 1.1 × 106 or 1.3 × 106 spores per gram ...
U N D E R conditions of ad libitum feeding, performance of swine is determined mainly by the voluntary feed consumption and the adequacy of nutrient levels in the diet. Recent emphasis has been on the establishment of optimum relationships between energy concentration and the levels of other nutrients in the diet. The relationship of source and concentration of dietary energy to level and quali...
The amount of feed consumed per day and the rate of food passage was measured in mink and European ferrets. Daily feed consumption averaged 40 and 42 g dry matter per kg body weight for male mink and ferrets and 53 and 49 g dry matter per kg body weight for female mink and ferrets, respectively. Using ferric oxide as a feed marker, no differences were observed in food passage time between mink ...
