The effects of Bovine Somatotropin on milk production and milk composition
MetadataShow full item record
Bovine Somatotropin is one of the first major biotechnological developments for agriculture and it is hypothesized that it increases milk production in dairy cattle. It is apparent that Bovine Somatotropin has the potential to be a powerful new tool for the dairy farmer. This study was undertaken to determine the effects of Bovine Somatotropin on milk production and milk composition for dairy cattle. The results of this study indicate that Bovine Somatotropin does influence milk production and milk composition. However, parity and days in milk are also significant variables affecting milk. Treated cows did produce milk longer on average than non-treated cows. However, it is not certain whether the longer length of lactation was due to BST. Therefore, it cannot be determine whether Bovine Somatotropin is the primary variable influencing milk production and milk composition.
