The mating behavior and reproduction performance in a multi-sire mating system for pigs [PDF]

, 2008
An important aim of organic animal production is to allow natural animal behaviour. Regarding reproduction techniques, artificial insemination is permitted but natural mating is preferred.

Histochemical indications for a chemically complex signal produced by the cervical gill slit gland of the pygmy sperm whale (Kogia breviceps)

The Anatomical Record, EarlyView.
Abstract The pygmy sperm whale (Kogia breviceps) possesses an exocrine gland associated with its false gill slit pigmentation pattern. The cervical gill slit gland is a compound tubuloalveolar gland that produces a holocrine secretion and displays maturational changes in size and secretory histology. While the morphology of the cervical gill slit gland

NÚMERO DE INSEMINAÇÕES ARTIFICIAIS POR ESTRO EM FÊMEAS SUÍNAS: ASSOCIAÇÃO COM O PERFIL ESTRAL E IMPACTO SOBRE O DESEMPENHO REPRODUTIVO

Ciência Animal Brasileira, 2010
In swine, multiple artificial inseminations (AI) are commonly performed per estrus due to the long estrus duration. This observational study aimed to evaluate the association among the number of AI conducted per estrus, the estrus duration and the ...

Social effects on behaviorally-scored and pedometer-detected estrus in beef cattle

The Journal of Reproduction and Development
The number of cows in estrus often influences estrus behavior; however, the effects of social order are not well documented. This study examined the effects of social order on the expression of behaviorally-scored and pedometer-detected estrus, combined ...

A companion to the preclinical common data elements for rigor, reproducibility and transparency in basic and translational epilepsy research. A report of the TASK3‐WG1A: Pharmacology Working Group of the ILAE/AES Joint Translational Task Force

Epilepsia Open, EarlyView.
Abstract Rigorous and transparent procedures in preclinical epilepsy research studies are important to permit assessing the reproducibility of their findings and derisk their translation into the clinic. The General Pharmacology Working Group of the ILAE/AES Task Force (TASK3‐WG1A) developed common data elements (CDEs) addressing rigor and transparency

Pemanfaatan Electronic Nose sebagai Sensor Kimiawi Urin Guna Melacak Birahi Sapi (ELECTRONIC NOSE AS URINARY CHEMICAL SENSOR FOR DETERMINING ESTROUS PHASE IN CATTLE)

Jurnal Veteriner, 2017
The timing of artificial insemination relies largely on behavioral observation of estrus. The problemfaced is that not all cattle shows signs of estrus significantly, which affect the accuracy of insemination,and therefore,the success rate of Artificial ...

Estimates of correlation between estrus behavior and estradiol concentrations during estrus [PDF]

, 2021
Estrus traits have economic value in dairy production systems and can potentially be incorporated into genomic selection. Three studies were performed to further understand selection responses. Study one and two explored the relationship between rump touches and number of steps during estrus.

Effects of 2, 4, 5-Trichlorophenoxyacetic Acid on Swiss-Webster Mice [PDF]

, 1977
Pure and Commercial samples of the herbicide 2,4,5-trichlorophenoxyacetic acid (2,4,5- T) were tested on Swiss-Webster mice for: (1) interruption of the estrus cycle and (2) teratogenic effects.
