橡胶籽饼饲喂肉用仔鸡的毒理学研究

Toxicological Studies on Rubberseed Cake for Feeding Broilers

橡胶籽饼含粗蛋白质21％～24％,作肉用仔鸡的蛋白质饲料,用量分别占饲粮的8％,16％,24％,10周龄时,随机抽样进行饲喂期增重、肝功能测定和肝组织切片镜检、胴体重、肌肉成份及品质的测定,结果无中毒性病理变化,生长发育良好,试验组与对照组间各项指标无显著性差异。

The undetoxified rapeseed cake of Brassica campestris and Brown mustard were used as protein additives in Starbro broilers' diet. The ratio of the additives to diet were 8%, 10% and 12% respectively. A group of ten-week old broilers were sampled randomly and were killed for pathological tests involving histological changes of the thyroid gland, serum T_3 and T_4, histological changes of the liver and liver functions, while examinations of the weight inciease of chickens during the experimental period, the carcass weight, the chemical composition and puality of muscle as well as the chromosome aberration were also made. The results showed no conspicuous changes and aberration rections when the ratio of additives in the diet reached at 12%.
