Fertility is critical for improved efficiency of dairy production but continues to be suboptimal in lactating dairy cows despite improvements in reproductive management and development of methods to improve insemination rates. One major problem on dairy herds is the incidence of cows that have not resumed ovulation by the end of the voluntary waiting period, termed anovular cows in this p…
The objective of this research proposal is to identify risk factors and factors that influence establishment and maintenance of pregnancy in anovular dairy cows. Six thousand dairy cows, primiparous and multiparous, lactating, will be synchronized with Presynch-Ovsynch protocol. Ovaries will be scanned by ultrasonographic examinations at the first and second PGF treatments of Presynch pro…
Pregnancy per AI (P/AI) and the plasmatic concentration of steroid hormones is less in lactating dairy cows than in dairy heifers. High milk production has been suggested as possible cause of this reduction in P/AI and concentrations of steroid hormones. High milk production and concurrent increase in dry matter intake has been associated with greater catabolism of steroid hormones in she…
