Influence of genetic capacity for lean tissue growth on rate and efficiency of tissue accretion in pigs fed ractopamine
Article Abstract:
An experiment was conducted from two sources of pigs possessing low and high lean tissue genotypes to study the influence of genetic capacity for lean tissue growth on responses of pigs to ractopamine. Results of the study show an increase in rate and efficiency of growth as well as improvement of carcass characteristics in pigs with ractopamine added diets. It was further shown that this response to ractopamine is greater in pigs with a high genetic capacity for lean tissue growth compared to those with a low genetic capacity.

Recombinant porcine somatotropin for sows during late gestation and throughout lactation
Article Abstract:
The injection of porcine somatotropin (pST) to sows in late gestation or during lactation did not improve milk production. Treatment with pST resulted in lower feed intakes and increased backfat loss. Sows given pST had increased susceptibility to heat stress, although dietary fat supplementation appeared to decrease this effect. Neither treatment was found to have an effect on litter size, but weaning weight appeared to be favorably affected by fat supplementation.
