recommendations! Published in 2024 at "Microscopy Research and Technique"

DOI: 10.1002/jemt.24556

Abstract: Estrus detection in buffaloes primarily relies on behavioral and physiological signs. Especially during summer, these signs are less prominent to recognize. Thus, estrus detection is a pronounced challenge within the realm of buffalo husbandry, particularly… read more here.

DOI: 10.1093/jas/skae019.042

Abstract: In beef cattle, 40% of cows that display estrus do not remain pregnant after embryo transfer (ET). Estrus is a physiological behavior influenced by the concentration of sex-steroids. The use of accelerometer devices for estrus… read more here.
