Effect of Different Protocols of Fixed-Time Artificial Insemination on Mucus, Ovarian Size, and Pregnancy of Mixed-Breed Cows in the Humid Tropics of Peru. [PDF]

Vet Med Int, 2023
The objective of the research was to evaluate three synchronization protocols for fixed‐time artificial insemination (FTAI) in Bos indicus with Bos taurus crossbred cows. Forty‐five cows of 5 ± 1.6 years were selected. The Jsynch treatment consisted of the application of an intravaginal device plus benzoate; on day 8, the device was removed and PGF2α ...

The effect of different FSH administration before ovum pick up on superstimulation response and oocyte yield

Reproduction in Domestic Animals, Volume 58, Issue 8, Page 1055-1062, August 2023., 2023
Abstract This study aims to evaluate the effect of synchronization and different superstimulation protocols on oocyte yield before ovum‐pick up (OPU) to provide a homogeneous follicle population. Animals in all study groups except the control group applied a synchronization protocol including modified ovsynch+progesterone and dominant follicle ablation

Effects of daily propylene glycol drenching during the Ovsynch protocol on fertility and metabolic parameters in lactating dairy cows

Reproduction in Domestic Animals, Volume 58, Issue 8, Page 1097-1103, August 2023., 2023
Abstract Negative energy balance (NEB) caused by restricted feed intake leads to body condition loss (BCS), increased metabolic stress and reduced fertility in dairy cows. Propylene glycol (PG) is a precursor of ruminal propionate for gluconeogenesis used to increase metabolic adaptation to the early postpartum period.
