Experimental auction markets were designed and used to investigate consumer preferences for sandwiches produced with meat from pigs treated with porcine somatotropin. A second-price, sealed-bid auction procedure was used to determine willingness to pay to exchange a pork loin sandwich with leaner meat from pigs treated with somatotropin for a similar sandwich with meat from untreated pigs. The ...

the objective of the present study was to determine polymorphism within the promoter region of somatotropin receptor genes in indigenous sistani cattle (bos indicus) and associations between this polymorphism and breeding value of birth weight. the pedigree structure was included by considering 1173 animals with 600 progeny birth weight data obtained from a zhark breeding station in sistan and ...

BACKGROUND Based on the increasing body of evidence that adults with human growth hormone (hGH) deficiency exhibit signs of impaired health, many countries have approved the use of hGH (somatotropin) as a replacement therapy in deficient adults. The results and efficacy of hGH therapy are strikingly consistent. Untreated hGH deficient adults are shown to have increased cardiovascular mortality,...

The isolation of growth hormone (somatotropin) from human, monkey, and whale pituitary glands has recently been reported (l-3). Preliminary studies on the hormone proteins from these species have suggested that phenylalanine is their sole N-terminal amino acid residue (l-3), in contrast to the two N-terminal residues, alanine and phenylalanine, which have been reported for the bovine somatotrop...

Recombinant DNA technology has provided a mechanism for large scale production of somatotropin (growth hormone). There is no question that exogenous administration of somatotropin (ST) to pigs significantly improves efficiency of growth and carcass composition. Microinjecting foreign DNA into the pronucleus of fertilized ova is the predominant method employed to produce transgenic animals. The ...

HISTORICAL DEVELOPMENT In the early 1930s, it was reported that injections of crude pituitary extracts increased growth rates in growing animals and milk production in lactating animals. Subsequent studies led to purification from pituitary extracts of two peptide hormones—prolactin and “growth hormone” or somatotropin—which are important to growth and lactation. Prolactin has many functions ra...

The aim of the study was to produce sensitive and specifi c polyclonal antibodies against somatotropin (ST) to be used for standardization of an ELISA to measure growth hormone (GH) level in serum and milk of lactating buffaloes. Recombinant bovine somatotropin (rbST), kindly donated by NHPP, California, USA was injected both in chicken and rabbit emulsifi ed with Freund’s complete adjuvant fol...

The review describes the problem of studying progressive changes hormones concentrations (parathyroid hormone, insulin, somatotropin, prolactin) in patients with chronic renal failure on pre-dialysis and dialysis stages. pathogenetic relationships between kidney function deterioration hormone as well their biological effects were evaluated. Parathyroid is considered an uraemic toxin, since its ...
