The Effect of Synchronizing with the PGF2α hormone on the Estrus Activity of Madura Cows [PDF]
BIO Web of ConferencesThis research aims to determine the biological response of administering the PGF2α hormone to the estrous activity of Madurese cows. This research method uses two observation techniques, namely estrus synchronization by administering the PGF2α hormone ...

Real-Time Cattle Interaction Recognition via Triple-stream Network [PDF]
arXiv, 2022 In stockbreeding of beef cattle, computer vision-based approaches have been widely employed to monitor cattle conditions (e.g. the physical, physiology, and health). To this end, the accurate and effective recognition of cattle action is a prerequisite. Generally, most existing models are confined to individual behavior that uses video-based methods to

Immunolocalization of steroidogenic enzymes in the vaginal mucous of Galea spixii during the estrous cycle. [PDF]
, 2017 BackgroundThe synthesis of sex steroids is controlled by several enzymes such as17α-hydroxylase cytochrome P450 (P450c17) catalyzing androgen synthesis and aromatase cytochrome P450 (P450arom) catalyzing estrogen synthesis, both of which must complex ...

Efficiency of CIDR-Based Protocols Including GnRH Instead of eCG for Estrus Synchronization in Sheep
Animals, 2019 Simple Summary This study examines the preovulatory and ovulatory events (in terms of the timing of onset of estrus behavior, preovulatory LH surge, and ovulation) and the yields obtained (in terms of ovulation rate, progesterone secretion, and fertility)
