Abstract In the postpartum period, there is an increase in non‐esterified fatty acids (NEFA) both serum and follicular fluid (FF) of cattle. The acid concentration results increased production reactive oxygen species (ROS) that can compromise bovine fertility. objectives this study were to characterize lipid profile found FF cows experiencing induced negative energy balance (NEB) evaluate effect α‐tocopherol prevention oxidative stress cows. Twenty‐nine beef divided into groups: (1) control;...
The effect of the exposure pregnant cattle to oestradiol benzoate (EB) or injectable long-acting progesterone (iP4), as well their use for early resynchronisation non-pregnant (NP) females within second week after timed AI (TAI), is yet be assessed. This study aimed assess pregnancy rate and embryonic loss cross-bred Bos taurus×Bos indicus beef heifers in response an EB- iP4-based strategy implemented 14 days first TAI. A total 677 cyclic (Braford Brangus; 24 months old) were subjected EB/P4...
