Bioclimatic, demographic and anthropogenic correlates of grizzly bear activity patterns in the Greater Yellowstone Ecosystem

Oikos, EarlyView.
Plasticity of diel activity rhythms may be a key element for adaptations of wildlife populations to changing environmental conditions. In the last decades, grizzly bears Ursus arctos in the Greater Yellowstone Ecosystem (GYE) have experienced notable environmental fluctuations, including changes in availability of food sources and severe droughts ...

Ovarian Dynamic in Ongole Grade Cattle After GnRH Injection in Ovsynch Protocol Based on Progesterone Device [PDF]

, 2015
PO cattle have weaknesses to show clear estrus signs which cause difficulty in artificial insemination implementation. The present study was designed to obtain ovarian dynamic as effect of GnRH injection in ovsynch protocol based on progesterone ...

A novel estrus-synchronization program for anestrous and cycling, suckled, beef cows [PDF]

, 1997
We used four herds at three Kansas ranches to evaluate the potential of two new estrus synchronization strategies to increase estrus expression and fertility of 911 crossbred suckled beef cows.

Kajian Metode Aplikasi Sinkronisasi Birahi menggunakan PGF2α pada kambing terhadap kualitas estrus, konsentrasi progesterone dalam darah dan tingkat kebuntingannya

Jurnal Sain Veteriner, 2020
A study of the application method of estrus synchronization with prostaglandin 2 alpha (PGF2α) preparations in local goats in Yogyakarta to determine the effectiveness of estrus synchronization based on the quality of estrus, the concentration of the ...

Inseminations at Estrus Induced by Presynchronization Before Application of Synchronized Estrus and Ovulation [PDF]

Journal of Dairy Science, 2005
A controlled field study examined conception rates after 2 timed artificial insemination (TAI) breeding protocols conducted on 2 commercial dairy farms. Estrous cycles in postpartum lactating cows were presynchronized with 2 injections of PGF(2alpha) given 14 d apart (Pre-synch) and then, after 12 d, the standard Ovsynch protocol (injection of GnRH 7 d

Monitoring the effects of ovariectomy on seasonal movement behavior in suburban female white‐tailed deer using internet of things‐enabled devices

Wildlife Biology, EarlyView.
Abundant deer populations often cause conflicts in suburban communities, yet traditional population reduction methods, such as controlled hunting, can be challenging to implement. Fertility control, specifically through ovariectomy, can limit reproduction and reduce populations in certain settings, but its effect on movement behavior remains poorly ...

The ecology of gestational growth in a wild cooperative mammal

Journal of Animal Ecology, EarlyView.
Using data from hundreds of wild pregnant meerkats, Thorley et al show that gestational growth varies widely, is shaped by nutrition but not social conditions, and improves pup survival without shortening telomeres. The fitness consequences and limited flexibility of prenatal growth likely enhance selection on early postnatal growth plasticity ...

Synchronization of breeding and its impact on genetic parameters and evaluation of female fertility traits

Journal of Dairy Science, 2023
: Achieving an acceptable level of fertility in herds is difficult for many dairy producers because identifying cows in estrus has become challenging owing to poor estrus expression, increased herd size, and lack of time and skilled labor for estrus ...

Effect of metformin on inflammation and bone damage in a rat model of medication‐related osteonecrosis of the jaw

European Journal of Oral Sciences, EarlyView.
Abstract This study investigated how chronic metformin administration modulates the cellular profile and inflammatory markers in a zoledronic acid‐based rat model of medication‐related osteonecrosis of the jaw (MRONJ). Male Wistar rats were allocated to different treatments: (i) naïve, (ii) MRONJ (zoledronic acid, 0.2 mg/kg, i.v.
