Effect of recombinant porcine somatotropin and dietary protein on pancreatic digestive enzymes in the pig

Article Abstract:

The effects of daily recombinant porcine somatotropin (rpST) injection and of dietary protein level on the pancreatic characteristics of growing pigs was investigated. The purpose was to determine whether the decreased fat deposition and enhanced feed efficiency of rpST-injected pigs are mediated by changes in pancreatic characters. The results showed that rpST does not have any significant effect on the pancreas. In contrast, dietary protein content had significant effects on the pancreas of growing pigs, manifested in increased weight and chymotrypsin content.

The effect of porcine somatotropin supplementation in pigs on the lipid profile of subcutaneous and intermuscular adipose tissue and longissimus muscle

Article Abstract:

The effects of porcine somatotropin on lipids and fatty acids in subcutaneous and intermuscular adipose tissue and longissimus muscles were studied in sixteen crossbred barrows given daily injections of either porcine somatotropin (pST) or placebo. Results show that pST decreases total lipid content of subcutaneous adipose tissue, reduces saturated fatty acids but does not affect the content of polyunsaturated fatty acids.
