Effects of copper source on phosphorus retention in broiler chicks and laying hens.
Copper sulfate is often added to broiler and laying hen diets at prophylactic dosages due to its antimicrobial and growth promoting effects despite reduced P digestibility, whereas P use from other Cu sources is unknown. Therefore, male broiler chicks were fed diets containing 0 or 250 ppm Cu from Cu sulfate (Cu SUL), Cu citrate (Cu CIT), Cu lysinate (Cu LYS), or CuCl from 9 to 22 d of age (8 c...
متن کاملEvaluation of the Efficacy of a Commercial Purified Phylosilicate to Reduce the Toxicity of T-2 Toxin in Broiler Chicks
The use of 2.5 kg/mt of a commercial HSCAS (Myco-Ad) have been previously demonstrated to effectively prevent the toxic effect of 1.25 ppm T-2 toxin (T-2) in broilers. An experiment was conducted to study the efficacy of a very low inclusion commercial purified phylosilicate (Myco-Ad A-Z) in preventing the deleterious effects of T-2 in broiler chicks. Thirty two 5-day-old Ross male broiler chic...
متن کاملRelative toxicity of gossypol enantiomers in laying and broiler breeder hens.
Gossypol, a natural component of cottonseed meal, exists in positive (+) or negative (-) enantiomeric forms, and their levels and ratio could be altered by developing new genetic strains of cotton. Two experiments were conducted to determine the relative toxicity of the individual gossypol enantiomers in laying and broiler breeder hens. In the first experiment, 25 individually caged Hy-Line W-3...
متن کاملEgg production, shell thickness, and other physiological parameters of laying hens affected by T-2 toxin.
T-2 toxin has been reported to cause severe oral lesions and neural disturbances in young broiler chickens. T-2 toxin, when added at a level of 20 mug per g of feed, caused oral lesions but no abnormal neural disturbances in young broiler chickens. T-2 toxin, when added at a level of 20 mug per g of feed, caused oral lesions but no abnormal neural symptoms in laying hens. T-2 toxin had no effec...
متن کاملProtein and Energy Requirements of Laying Hens and Broiler Breeders
Layer and Breeder rations are still evaluated, as a rule, on the basis of their protein content, expressed as "percent protein". This is the easiest and most practical criterion, but unfortunately it is a relative measure, depending on general feed consumption. The latter hardly relates to the productive traits of the hen, being dependent primarily on the energy content of the feed and on the e...
