Etawa Goat Estrus Quality with Estrus Synchronization

Journal of Applied Veterinary Science and Technology, 2021
Background: Estrus synchronization is a way to get a herd of cattle estrus at the same time. This method can increase the reproductive success of livestock, thereby increasing production and population.

Estrus-Cycle Regulation of Cortical Inhibition [PDF]

Current Biology, 2018
SummaryFemale mammals experience cyclical changes in sexual receptivity known as the estrus-cycle. Little is known about how estrus affects the cortex although alterations in sensation, cognition and the cyclic occurrence of epilepsy suggest brain-wide processing changes.

Vocalization as an indicator of estrus climax in Holstein heifers during natural estrus and superovulation. [PDF]

Journal of Dairy Science, 2018
The reliable detection of estrus is an important scientific and practical challenge in dairy cattle farming. Female vocalization may indicate reproductive status, and preliminary evidence suggests that this information can be used to detect estrus in ...

Detection Method of Cow Estrus Behavior in Natural Scenes Based on Improved YOLOv5

Agriculture, 2022
Natural breeding scenes have the characteristics of a large number of cows, complex lighting, and a complex background environment, which presents great difficulties for the detection of dairy cow estrus behavior.

Effect of a targeted reproductive management program designed to prioritize insemination at detected estrus and optimize time to insemination on the reproductive performance of lactating dairy cows.

Journal of Dairy Science, 2022
The primary objective of this randomized controlled experiment was to evaluate the insemination dynamic and reproductive performance of cows managed with a targeted reproductive management (TRM) program designed to prioritize artificial insemination (AI)

Evaluation and characterization of estrus alerts and behavioral parameters generated by an ear-attached accelerometer-based system for automated detection of estrus.

Journal of Dairy Science, 2021
Our objectives were to evaluate the performance of an ear-attached automated estrus detection (AED) system (Smartbow; Zoetis) that monitored physical activity and rumination time, and to characterize AED system estrus alert features (i.e., timing and ...

Determination of estrus in Aceh cows based on the van Eerdenburg method

Ovozoa: Journal of Animal Reproduction, 2022
Accurate determination of estrus status in an animal based on an appropriate estrus detection method can guarantee the cows' pregnancy after mating. This study aims to determine the estrus status of Aceh cows using the van Eerdenburg estrus behavior ...
