Review: Behavioral signs of estrus and the potential of fully automated systems for detection of estrus in dairy cattle.

Animal, 2017
Efficient detection of estrus is a permanent challenge for successful reproductive performance in dairy cattle. In this context, comprehensive knowledge of estrus-related behaviors is fundamental to achieve optimal estrus detection rates. This review was

Estrus Detection and Estrus Detection Aids

Journal of Dairy Science, 1975
There is no substitute for good management. Each animal should be identified carefully. The herds man should know all signs of estrus or impending estrus. In addition, for visual detection of estrus to be highly effective, sufficient time must be taken at least twice a day to catch animals with a short estrus period. Presently there are two visual aids

Timed artificial insemination plus heat I: effect of estrus expression scores on pregnancy of cows subjected to progesterone-estradiol-based protocols.

Animal, 2019
Expression of estrus near timed artificial insemination (TAI) is associated with greater fertility, and estrus detection could improve TAI fertility or direct TAI management, although accurate estrus detection can be difficult and time-consuming using ...

Towards Sustainable Dairy Management - A Machine Learning Enhanced Method for Estrus Detection

Knowledge Discovery and Data Mining, 2019
Our research tackles the challenge of milk production resource use efficiency in dairy farms with machine learning methods. Reproduction is a key factor for dairy farm performance since cows milk production begin with the birth of a calf.

The effects of different PMSG doses on estrus behavior and pregnancy rate in Angora goats.

Animal, 2019
Artificial insemination protocols depend on efficient behavioral estrus detection and insemination time in Angora goat. Therefore, we aim to determine the accuracy of an estrus scoring system in Angora goats with different PMSG doses during the breeding ...
