The effect of cooling on the blood composition and seminal characteristics of crossbred bulls.

Abstract

In 8 healthy cattle bulls (6 Holstein Friesian X Red Dane X Sahiwal and 2 Holstein Friesian) the effect was studied of cooling on the blood and seminal parameters during the hot summer months June to September in Ludhiana, Punjab, India. Favourable effects were found only in some blood values. The seminal characteristics do not differ from those of the control group. Rectal body temperatures remained also constant, whereas the respiration rates were higher in the control group.
