摘要: 1. The effects of maize particle size and steam pelleting on growth nutrient utilisation were studied with broiler chicks. 2. presence or absence 10 μg/kg 1,25 dihydroxycholecalciferol in diets adequate deficient phosphorus was also investigated. Food efficiency superior the fine but calcium retention phytate greatest coarse diets. Pelleting improved food both experiments while decreased. 3. Addition 1,25-dihydroxycholecalciferol to diet increased 16-d body weight, bone ash, plasma dialysable retentions total decreasing deficiency rickets tibial dyschondroplasia. 4. There significant interactions between form. improvement observed reduced when pelleted. When fed as a mash, coarse...
