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.

Infrared Thermography as a Potential Non-Invasive Tool for Estrus Detection in Cattle and Buffaloes

Animals, 2023
Simple Summary Estrus detection is the most important factor for dairy animals (cattle and buffaloes) to get them pregnant on time for efficient production. Over a period of time, increased production potential caused increased stress and weakened estrus

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 ...

The Stage of the Estrus Cycle Is Critical for Interpretation of Female Mouse Social Interaction Behavior

Frontiers in Behavioral Neuroscience, 2020
Female animals in biomedical research have traditionally been excluded from research studies due to the perceived added complexity caused by the estrus cycle.

Use of protocol with prolonged proestrus with and without eCG in dual purpose dairy Holsteins cows in the Ecuadorian Amazons [PDF]

SPERMOVA, 2020
The objective was to evaluate the effect of eCG on presence estrus, ovulation time, preovulatory follicle diameter and pregnancy rate in Holstein cows treated with a prolonged proestrus protocol in the Ecuadorian Amazon.

Determination of estrus duration based on cervical mucus characteristics in Aceh cattle using camera-equipped artificial insemination endoscope

Ovozoa: Journal of Animal Reproduction, 2022
This study aimed to determine the length of the estrus period in Aceh cows based on changes in the characteristics of cervical mucus observed using a camera-equipped artificial insemination (AI) endoscope.

Effects of subcutaneous progesterone injection as a short-time estrus synchronization protocol in ewes: a preliminary study [PDF]

The Iranian Journal of Veterinary Science and Technology, 2022
The present study aimed to evaluate the effect of short-time progesterone injection subcutaneously (SC) on estrus synchronization of Baluchi ewes. All ewes received one dose of PGF2α (15 mg) and then were divided into two groups.

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

Frontiers 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.
