| 摘 要： | 该试验设计了9种能量或蛋白质水平不同的饲粮，研究了不同饲粮处理下睾丸发育情况。结果表明：饲粮能量水平过低或蛋白质水平过高对肉用雄仔鸡睾丸相对生长速度及其曲细精管的发育有一定的阻碍作用；睾丸相对生长速度越大，曲细精管的发育程度越好。

| Abstract: | In the experiment reported, broilers were fed diets with different combinations of energy (3 levels) and protein (3 levels). Inadequate energy or excessive protein in the diet was shown to decrease the relative growth rate of the testis of male broilers and inhibit the development of the seminiferous tubule. The number of layers of spermatogenic cells in the seminiferous tubule increased with relative growth rate of the testis. |

| Keywords: | energy and protein broiler development of testis |
