Somatotropin physiology — a review

  • 1994
  • Issue: 1
  • Volume: 24
J.G. van der Walt Page: 1 - 9

The continuing search for improved efficiency has led to the introduction of exogenous growth and lactation promotants to enhance traditional animal production systems. Various species-limited somatotropins have been synthesized by means of recombinant gene technology, thereby allowing milk production in…
