摘要: 通过测量不同日龄肉鸡与蛋鸡的法氏囊指标研究其生长发育规律。肉鸡分别在10个不同日龄随机选取10只健康鸡。蛋鸡分别在12个不同日龄随机选取健康的公鸡、母鸡各10只。宰杀后,摘取法氏囊称重,测量其长、宽、高,并制作石蜡组织切片进行HE染色,然后显微镜下测量法氏囊滤泡的长、宽、皮质及髓质厚度。结果表明,肉鸡法氏囊重量随日龄的增长不断增加,到49日龄达到最大,其滤泡的生长也符合此规律;蛋鸡的法氏囊重量从1~68日龄不断增长,并且到68日龄时达到最大值,68~96日龄逐渐减小,其滤泡生长也符合此规律,而法氏囊指数与日龄和体重的增加呈现一定规律的正相关。

Abstract: Measuring the index of bursa of fabricius to research the law of growth.10 health broilers from ten different days age were selected randomly from broilers. And 10 health layers from twelve different days age were selected randomly from layers. Bursa of fabricius were weighted after aliveness weight and dissection. Then measured the length, width and thickness of bursa of fabricius. Meanwhile made paraffins section for HE staining, and measured the length, width, thickness of cortex and medulla of folliculus. The results showed that the weight increase of bursa of fabriciu were positive correlation along with days and weight increasing for broilers, and grew to the top on the 49 day-age, and the law of growth for folliculus was same to the bursa of fabriciu. The weight increase of bursa of fabriciu was growing from 1 to 68 days old, and reduced from 68 to 96 days old for layers, and the law of growth of folliculus was same to the bursa. However, the ratio of bursa of fabriciuto weight had certain correlation along with days and weight increasing for broilers and layers.

Key words: broiler chicken; layer chicken; bursa of fabricius; folliculus
