Pretreatment with recombinant bovine somatotropin
enhances the superovulatory response to FSH in heifers.
EFFECT OF BOVINE SOMATOTROPIN
(bST) ON PERIPUBERTAL GROWTH RATES OF HOLSTEIN HEIFERS FED TWO PLANES OF NUTRITION
The decreased plasma concentrations of urea during supplementation of rbST might be due to the effect of bovine somatotropin
via N-actyl glutamate, on carbamyl phophate synthetase, a key enzyme in the urea cycle (Oddy and Lindsay, 1986).
Items likely to feature on the agenda include:- "e-Europe" initiative - an information society for all- Regulation on the compulsory beef labelling scheme- Regulation on residues of BST (Bovine Somatotropin
) in food- Community assistance 2000-2006 for the stabilisation process for certain countries of South-East Europe *Official visit of Mrs Schreyer to Poland - December 9 - 10.
The reduction of milk yield is attributed to a decrease in mammary blood flow (MBF) coinciding with the decline of plasma bovine somatotropin
Two new superstores operated by P&C Food Markets, Syracuse, N.Y., have been selling milk labeled as free of BST (bovine somatotropin
), the synthetic growth hormone given to cows to stimulate milk production.
Effect of a prolonged-release formation of N-methionyl bovine somatotropin
(sometribove) on milk composition.
Pending an agreement on this issue, it postponed proposing maximum residue limits for the dairy yield-boosting hormone bovine somatotropin
Effect of bovine somatotropin
administered to periparturient dairy cows on the incidence of metabolic disease.
Advice is likewise given on the methodologies for carrying out chronic and acute risk assessments for pesticide residues in food.BST and other growth hormones.Prior to decisions on whether to extend or scrap the EU's long-standing moratorium on the marketing and use of Bovine Somatotropin
(BST) which expires on December 31, 1999, the scientific committees were asked for their Opinion on this question.
Genetic polymorphism within the bovine somatotropin
(bST) gene detected by polymerase chain reaction and endonuclease digestion.
(bST) is known as a homeorhetic hormone connected with both growth and lactation, but the mechanism of action of bST on milk production is a controversial area, as receptors for bST have not been demonstrated on secretory epithelial cells of mammary tissue (Akers, 1985).
