...hysiological response to thermal stress from Bos Indicus cows and acclimatization to the tropical conditions of Pakistan.Therefore, further study is needed on acquisition of genes from Bos Indicus for low physiological response in crossbred cows.

...gated via the effects of thermal stress on superoxide anion (O2-) production, superoxide dismutase (SOD) activity, glutathione (GSH) and adenosine triphosphate (ATP) concentration, as well as nitric oxide synthase (NOS) activity and nitric oxide (NO) concentration catalyzed by NOS. Based on biochemical analysis of the above, results showed that O2- production could be induced significantly after cold stress at 15°...

...to reduced resistance to thermal stress. Cows with 50.0% exotic blood and those born in spring showed a slightly shorter age at first calving. The crossbred cows of genetic group HF 62.5% tended to show shortest ovulation intervals and the summer calvers showed significantly highest intervals. Based on results of this study it is suggested that cows calving in summer show lowest calving interval. Crossbred cows with 50% exotic blood showed earliest age at firs...
