The effect of porcine somatotropin (pST) on the lipid profiles of adipose tissue and muscle was investigated. Sixteen crossbred barrows were injected daily with either 3 mg of pST or a placebo. After slaughter, total lipid and fatty acid composition of raw subcutaneous (SC) adipose and intermuscular (IM) adipose tissue and longissimus muscle were determined. The SC adipose tissue from pST-treated pigs had a 7.5% decrease in total lipid content; specific fatty acids 16:0, 18:0, and 18:1(n-9)c decreased most. The IM fat from pST-treated pigs had lower levels of 16:0 and 20:0. There was no effect of pST treatment on the lipid profile of the longissimus muscle. The data suggest that pST treatment produces small but significant changes in the saturated fatty acid content of adipose tissue in pigs.
研究了猪生长激素（pST）对脂肪组织和肌肉脂质谱的影响。16头杂交公猪每天注射3毫克pST或安慰剂。屠宰后，测定了生皮下（SC）脂肪、肌间（IM）脂肪组织和背最长肌的总脂质和脂肪酸组成。pST处理猪的SC脂肪组织总脂质含量降低了7.5%；特定脂肪酸16:0、18:0和18:1（n-9）c下降最多。pST处理猪的IM脂肪中16:0和20:0的水平较低。pST处理对背最长肌的脂质谱没有影响。数据表明，pST处理会使猪脂肪组织中饱和脂肪酸含量产生微小但显著的变化。
