Bovine somatotropin (bST) has been isolated from pituitary glands and compared in a variety of chemical analyses and bioassays with somatotropin derived from recombinant Escherichia coli. Comparison of pituitary extracts and purified bST by Western blot analysis of two-dimensional gels suggested that the immunoreactive somatotropin species present in the extract were also present in the purifie...

  The aim of this research was to evaluate the effects of oral recombinant bovine somatotropin (RBS) 1% on growth performance of rainbow trout (Oncorhynchus mykiss). 600 rainbow trout weighing 46±1 grams were randomly allotted in two groups including: 1) the control group and 2) RBS treated group, each in three replicates. The fish were hand-fed with commercial pellets. The fish received 200g R...

Human somatotropin competed for 125I-human somatotropin binding to hepatocytes from female or male rats. Bovine somatotropin and prolactin each inhibited part, but not all, of the uptake of 125I-human somatotropin. The binding of 125I-prolactin was inhibited by human somatotropin and prolactin, but not by bovine somatotropin. Bovine somatotropin and human somatotropin, but not prolactin, compet...

Recombinant bovine somatotropin (rBST) changes metabolism to spare glucose for milk synthesis in cows. Ceramides inhibit insulin responsiveness adipocytes and are associated with resistance production The mechanisms by which rBST supports lactation may involve ceramide. Eight multiparous lactating Holstein cows were enrolled a 2 × replicated Latin square design 14-d periods. Cows received singl...

Use of bovine somatotropin to increase product ion of milk and milk solids poses the problem of allocation within herd and implications for genetic evaluatat ion records with and without bovine somatotropin were simulated for different correlations between performance with and without t reatment and response to it. Resulting within-herd variances and accuracy and bias in sire evaluations were c...

The production and profit impacts of recombinant Bovine Somatotropin (rbST) on select New York dairy farms were estimated using data over the years 1994 through 2004, by comparing matching farms which use and do not use rbST. The use of rbST increases milk production per cow and decreases the cost of production per hundredweight of milk. The cost penalty (cost reduction) is $0.39 per hundredwei...
