Abstract

Components of assisted reproduction technologies (ART), such as sperm cryopreservation, artificial insemination, superovulation and pouch young surrogacy, have been developed for a range of Australian and American marsupials. However, methods to effectively control ovarian function, arguably the...

Abstract

Reproductive success in females relies primarily upon better understanding of fundamental ovarian processes to facilitate captive reproductive management and ultimately the development of assisted reproductive technologies as an alternative tool for conservation breeding of endangered wildlife...

Abstract

In the past decade, studies on reproductive biology, endocrinology, and assisted reproductive technologies (ARTs) in the domestic cat have contributed to a lot of progress in conservation breeding of wild felids. However, the 36 species of the Felidae family have species- and individual-specific...

Abstract

Two experiments were performed to test the hypothesis that administering PGF concurrent with timed artificial insemination (AI) in lactating dairy cows would enhance pregnancy per AI (P/AI). In experiment 1, lactating Holstein cows (n=289) in one herd were enrolled after a non-pregnancy diagnosis ...

Abstract

The aim of the present study was the establishment of an effective protocol for cryopreservation of psittacine semen. Therefore, pooled semen samples of 30 cockatiels (Nymphicus hollandicus) were diluted with modified Lake diluent (1:4), partitioned into four equal parts. Three portions were mixed...

Abstract

Background: Poor reproductive efficiency of river buffalos hampers the production capabilities of animals. Buffalos are mainly considered poor breeders owing to the constrained expression of estrus behavior. Failure to display heat signs is an indication of improper functionality of signaling...

AbstractFull Text

Complex vertebral malformation (CVM) has considerable economic impact on dairy cattle breeding due to extensive use of artificial insemination (AI). Identifying the carrier is an important factor to reduce the incidence of the genetic disorder. The study was conducted to identify the carriers of...

Abstract

Implantation is a critical process wherein the dam accepts the semi-allogenic embryo, characterized by certain vital immunological changes involving certain factors and cytokines. The current study was undertaken in Sahiwal cows to analyze the changes in certain selective immunological components...

Abstract

The sex ratio (proportion of male calves born) can vary as a result of many factors. The biological mechanisms of their effects are numerous. First the origin of oocytes (sex ratio varies between the right ovary and left ovary), while the influence of the horn that hosts the fetus does not appear...

Abstract

The secondary sex ratio, defined as the proportion of males at birth is 52% in cattle, with variations depending on the populations studied 46 to 57%. It is higher in the early stages of embryonic development, and the males die proportionally more often conceptus during pregnancy than females...
