Estrus synchronization schemes and application efficacies in anestrus lanzhou fat-tailed ewes

, 2016
This study aims to investigate the estrus efficacy of FIS (fluorogestone intravaginal sponges)/eCG (equine chorionic gonadotropin) and cloprostenol treatments to establish the optimum protocols for estrus synchronization in ewes.

Neuronal SIRT1 Regulates Metabolic and Reproductive Function and the Response to Caloric Restriction. [PDF]

, 2019
Sirt1 is an NAD-dependent, class III deacetylase that functions as a cellular energy sensor. In addition to its well-characterized effects in peripheral tissues, emerging evidence suggests that neuronal Sirt1 activity plays a role in the central ...

Behavioral and hormonal pattern of repeat breeder cows around estrus.

Reproduction, 2015
Repeat breeder (RB) cows were compared with normal (CTRL) ones with respect to behavioral estrus intensity, endocrine patterns and concentrations of plasma estradiol, progesterone and LH around estrus, and ovulation timing. A total of 27 and 31 cycles in

Expression and detection of estrus in dairy cows: the role of new technologies.

Animal, 2014
Despite the widespread adoption of hormonal synchronization protocols that allow for timed artificial insemination (AI), detection of estrus plays an important role in the reproductive management program on most dairies in the United States.

Early positive tactile stimulation reverses the increase of anxiety and decrease of sociality induced by early chronic mechanical pain in mandarin voles

Integrative Zoology, EarlyView.
This study used a tail‐pinching model during development to simulate mechanical pain experienced by pups in high‐social mandarin voles (Microtus mandarinus). Subsequently, brush‐like positive tactile stimuli were applied to the backs of the mandarin voles.

An ex ante analysis on the use of activity meters for automated estrus detection: to invest or not to invest?

Journal of Dairy Science, 2014
The technical performance of activity meters for automated detection of estrus in dairy farming has been studied, and such meters are already used in practice. However, information on the economic consequences of using activity meters is lacking.

Molecular Method Based on Hydrolysis Probe Assays to Identify the Sex Chromosomes of Iberian Desman (Galemys pyrenaicus) Using Non‐Invasive Sampling

Integrative Zoology, EarlyView.
To monitor populations of an endangered species such as Galemys pyrenaicus in the Extremadura area, qPCR techniques have been used to determine sex, using non‐invasive sampling techniques. ABSTRACT Desmans belong to the subfamily Desmaninae, which are members of the family Talpidae.
