Absorbed organic residues from pot...

The sugar of the blood of dairy animals has been the subject of considerable investigation in its relation to milk secretion and disease. It is the precursor of the lactose of milk. Meigs (11)^ has presented a thorough review of the literature on this little-known phase of metabolism. There is good evidence to show that milk sugar is derived from the glucose of the blood, though the process by ...
It has long been known that season of the year has major impacts on dairy animal performance measures including growth, reproduction, and lactation. Additionally, as average production per cow has doubled, the metabolic heat output per animal has increased substantially rendering animals more susceptible to heat stress. This, in turn, has altered cooling and housing requirements for cattle. Sub...
A total of 1501 oral swab samples from Pakistan, Afghanistan and Tajikistan were collected from clinically healthy animals between July 2008 and August 2009 and assayed for the presence of foot-and-mouth disease virus (FMDV) RNA.
