PCR-RFLP in FSHR gene 5'–flanking region with exon 1 digested by restriction endonuclease TaqⅠdemonstrated that the frequencies of allele A (0.5500) and genotype AA (0.5000) in twinning cows were higher than that of allele A (0.3500) and genotype AA (0.3000) in monovular cows for Qinchuan cattle, while The frequencies of allele B (0.5937) and genotype BB(0.6875) in twinning cows were higher than that of allele B (0.5416) and genotype BB (0.4167) in monovular cows for Holstein cattle. Key words: Bovine; Twinning; FSHR gene; PCR-RFLP

FSHR基因5'端（包括侧翼序列和第一外显子）的限制性内切酶TaqⅠ的PCR-RFLP标记研究发现，在秦川牛中双胎母牛的A基因频率（0.5500）和AA基因型频率（0.5000）分别高于单胎母牛的A基因频率（0.3500）和AA基因型频率（0.3000）；在黑白花奶牛中双胎母牛的B基因频率（0.5937）和BB基因型频率（0.6875）均高于单胎母牛的B基因频率（0.5416）和BB基因型频率（0.4167），也就是FSHR基因的5'端的PCR-RFLP标记在一个品种内单胎母牛和双胎母牛之间有一定趋势，但两个品种的趋势不同。

Eight multiparous Holstein cows in early lactation which had the adjacent milk yields,parturition date and performance,were divided into 4 groups,two cows of each group.

选择8头泌乳前期的经产中国荷斯坦奶牛，要求产奶量、胎次、产犊日期相近，健康无疾病。分为4组，每组2头，采用4×4拉丁方设计，各组采用相同的基础日粮(含锌量34.63mg/kg干物质)。

Eight healthy multiparous Chinese Holstein cows in early lactation were chosen. There were four high-yielding cows and four middle-yielding cows, separately with similar milk yield, parity and parturition date and body weight.

选择8头经产泌乳早期的中国荷斯坦奶牛，其中4头中产奶牛和4头高产奶牛(健康无病，中产奶牛和高产奶牛分别具有相近的产奶量、胎次、产犊日期和体重)，分别采用4×4拉丁方试验设计进行试验，研究日粮中补充染料木黄酮对奶牛的影响。

Twenty multiparous healthy holstein cows with similar milk period and similar milk yield were randomly assigned to one of five treatments(4 cows per treatment) in 52 d trial.

Giesy（2002）研究每天每头奶牛日粮中添加CLA50、100 g，结果发现乳脂率分别降低29%和34%；乳脂率从3.35%降低到3.34%需要3 g CLA，而从2.4%降低到2.3%则需要31.8 g CLA，说明每天添加50 g CLA降低乳脂率从经济方面来讲比较合理，但乳脂率降低还没有达到最大化。
