The effect of wheat gluten or extracted soybean meal (300 g of crude protein/head/day) on milk yield, composition and its physical properties was analysed in 53 cows of Polish Holstein-Friesian breed ...
摘要通过长距离PCR从山羊基因组DNA分两段扩增山羊β乳球蛋白（β-lactoglobulin,BLG）基因，扩增出的两个片段分别克隆到T载体上，利用BLG基因序列自身存在的NarI单酶切位点进行拼接，获得了全长为7.2kb的山羊BLG基因克隆，并构建了它的真核表达载体，经酶切鉴定和序列分析证实了克隆的正确性。用线性化的BLG基因显微注射小鼠受精卵以建立转基因鼠，经PCR和Southern印迹分析...
