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

open access: yesJournal 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 dairy cattle.

Faculty of Veterinary Medicine, University of Forestry, Sofia, Bulgaria [PDF]

open access: yesBulgarian Journal of Veterinary Medicine, 2020
A characteristic feature of water buffalo heifers is that they approach breeding maturity later than bovine heifers. From a physiological and endocrinological view, this is related to a later puberty, which affects the overall reproductive performance of

Estrus Detection and Estrus Detection Aids

open access: yesJournal 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

Analysis of reproduction-related transcriptomes on pineal-hypothalamic-pituitary-ovarian tissues during estrus and anestrus in Tan sheep

open access: yesFrontiers in Veterinary Science, 2022
Seasonal estrus is an important factor limiting the fertility of some animals such as sheep. Promoting estrus in the anestrus season is one of the major ways in improving the fecundity of seasonally breeding animals.

Estrus cyclicity of spinogenesis: underlying mechanisms [PDF]

open access: yesJournal of Neural Transmission, 2009
Hippocampal spine density varies with the estrus cycle. The cyclic change in estradiol levels in serum was hypothesized to underlie this phenomenon, since treatment of ovariectomized animals with estradiol induced an increase in spine density in hippocampal dendrites of rats, as compared to ovariectomized controls. In contrast, application of estradiol

Gut Microbiota in Dholes During Estrus [PDF]

open access: yesFrontiers in Microbiology, 2020
The co-evolution of gut microbes and the host plays a vital role in the survival and reproduction of the host. The dhole (Cuon alpinus) has been listed as endangered species by the International Union for Conservation of Nature; therefore, conservation and effective breeding of dholes are essential. Effective estrus can promote reproduction.
