摘要

在12周的时间里,对两组具有卵巢循环功能和进一步生长潜力的英国弗里西小母牛分别饲喂两种水平的限制饲料。饲喂高水平饲料的8头(SP组)和饲喂低水平饲料的5头(LP组)在第6周人工授精受孕。SP组和LP组的平均(和sem)体重变化分别为0.24(±0.024)kg day - 1和- 0.19(±0.039)kg day - 1。3 ~ 12周期间,5头LP母牛血浆泌乳素、甲状腺素和胰岛素的平均浓度分别为8头SP母牛的39%、67%和74%。结果提示,催乳素、甲状腺素和胰岛素对犊牛妊娠前期和妊娠早期的生长发育有一定的影响。

Possible roles for prolactin, thyroxine andinsulin in the growth of heifers before and during early pregnancy

Two groups of British Friesian heifers with cyclic ovarian function and thepotential for further growth were individually fed a restricted diet at two levels over a 12-week period. Eight heifers receiving the higher level of feed (SP group) and five receiving the lower level (LP group) became pregnant by artificial insemination at week 6. Mean (and sem body weight changes in the SP and LP groups were respectively 0.24 (±0.024) kg day−1 and −0.19 (±0.039) kg day−1. Over the period from weeks 3–12, mean concentrations of plasma prolactin, thyroxine and insulin in the five LP heifers were 39%, 67% and 74%, respectively, of those in the eight SP heifers. The results suggest that prolactin, thyroxine and insulin have roles in the growth of heifers before and during early pregnancy.
