The objective of this study was to compare the environmental impact of Jersey or Holstein milk production sufficient to yield 500,000 t of cheese (equivalent cheese yield) both with and without recombinant bovine somatotropin use. The deterministic model used 2009 DairyMetrics (Dairy Records Management Systems, Raleigh, NC) population data for milk yield and composition (Jersey: 20.9 kg/d, 4.8%...

A new scientific study by Vicini et al. published in the July issue of the prestigious Journal of the American Dietetic Association (JADA) reports the results of the first in-depth survey study comparing retail milk for quality, nutritional value and levels of different milk hormones, including bovine somatotropin (bST). The study that we published found that there were “no meaningful differenc...

Application of the technologies of genetic engwering in the dairy industry will begin with!” 5 years, probably wth the use of bovine somatotropin as a la&bon sbmulant. There are several other likely developments which may manipulate the animal, the plant or the wnen micro-organism to increase or dwersity production or to decrease milking frequency. To take full advantage of increased potential ...
