Dairy cows display a partial preference for being outside, but little is known about what aspects of the outdoor environment are important to cows. The primary aim of this study was to test the preference of lactating dairy cattle for pasture versus an outdoor sand pack during the night. A...

As in such a low-input system the fertility and secondary traits such as robustness against metabolic challenges of dairy cows is of crucial importance, it is questionable whether conventional dairy cow types, which were selected primarily for milk production under high-input conditions, are most ...

Significant difference was found within the milk yield (p<0.01), calving interval (p<0.05) and birth weight of calves (p<0.01) of different types of dairy cows. In case of lactation length, gestation length and service per conception, there were no significant differences (p>0.05). Highest...
This study was undertaken to evaluate the performances of economic trait of different dairy cows under village condition. The result showed that the average milk production of Holstein-Friesian cross, Sahiwal cross, Sindhi cross and indigenous dairy cows were 6.29 3.16, 4.72 1.01, 3.73 1.10 and ...

Antimicrobial treatment to all cows above 200,000 cells/mL at last control, with the use of ITS on all cows, seems a good choice in most dairy farms. These findings could be used to convince farmers to adopt this strategy at dry-off. 展开 ...
Rumen microbial composition and functions have vital roles in feed digestion and fermentation and are linked to feed efficiency in cattle. This study selected Holstein cows, which are high in both milk protein content and milk yield, to analyse the relat
