Effect of recombinant porcine somatotropin on energy and protein utilization by growing pigs: interaction with capacity for lean tissue growth

Article Abstract:

The administration of porcine somatotropin was found to increase the rate of lean tissue gain and lean tissue lipid deposition in all groups of pigs. Fat deposition was reduced to almost zero when energy restriction was added to pST treatment. Hence, pST may be used as a method of manipulating body fat. Heat production was found to increase, possibly due to metabolic effects in different body compartments to varying degrees. Although little is known about pST effects at the tissue level, a 40% increase in liver oxidative capacity was detected.

Cloning and characterization of the bovine somatostatin gene

Article Abstract:

The DNA of the bovine somatostatin gene (bSRIF) was extracted from blood through the use of a commercial kit and was later isolated through sequential cloning. Both strands of the cloned PCR products were used to determine the consensus sequence, which was later affirmed by amplification reaction data. The bSRIF promoter was found to be 89% and 91% identical to the promoters of human, mouse and rat, while the intron has 86%, 84% and 81% identity with rat, human and mouse SRIF introns, respectively.

Characteristics of somatotropin and prolactin profiles in young dairy sires before and after a 72-hour fast during different seasons

Article Abstract:

The concept that somatotropin and prolactin profiles are related to genetic merit in dairy sires prompted a study to detect concentrations of these hormones before and after a 72 hour fast during different seasons. A computerized peak detection program showed seasonal variation in values which could cause an error in selection techniques involving endocrine characteristics. Fasting shows a significant improvement in the efficacy of this method.
