A study was done to evaluate the effect of using progesterone (P4) intravaginal device (CIDR: controlled internal drug-releasing dispenser) to synchronise the return to oestrus of previously timed inseminated (TAI) dairy heifers, and to evaluate embryo survival and pregnancy rate (PR) in the return to oestrus heifers. At the onset of the artificial insemination (AI) breeding period (day -9), he...

Artificial insemination with donor sperm yields pregnancy rates similar to the general fertile population with the woman's age being the best predictor for success. This article reviews the indications for donor insemination and the current American Society for Reproductive Medicine guidelines for screening both the donors and recipients. For most women, timing the insemination the day after de...

The chapter will deal with the use of artificial insemination (AI) in animals and humans, both currently and in the future, with particular emphasis on comparative aspects between species. Although AI (in the form of intrauterine insemination) is not frequently used in human patients, it is the most commonly used method of breeding food production animals in developed countries, with more than ...

Objective: The aim of the present study was to evaluate artificial insemination techniques on reproductive performance in Ghezel ewes synchronized with CIDR during breeding season. Methods: All ewes were treated with controlled internal drug release device (CIDR) inserted into the vagina of the ewes for 14 days. All ewes were treated a single intramuscular (IM) dose of PMSG was injected. In thi...

Reproductive performance was evaluated in non-lactating crossbred ewes to which were administered the exogenous GnRH and PMSG. The ewes were randomly allocated in three treatment groups (n=40).After accurate detection of estrus and 2 hours prior to mating, 2.5 mL of distilled water and 2.5 mL of GnRH were injected intramuscular to each ewe of the first (control) and second group, respectively. ...

No domestic availability to breeder turkey stocks and turkey hatching eggs prompted the present experiment that aimed to evaluate the feasibility of a conventional artificial insemination (AI) procedure in British United Turkey (BUT) for the first time in Iran. Broiler turkeys were restrictedly fed, grown for 46 weeks, and used for the current study (10 turkey toms and 24 turkey hens in total)....

A total of 2567 indigenous Greek ewes (Chios, Vlachiki and VlachikixChios breeds) were used to determine the optimum time for insemination, following synchronization of oestrus with MAP-impregnated intravaginal sponges and PMSG during non-breeding season. Within each breed group, the ewes were divided into three subgroups and submitted to a double blind cervical artificial insemination 48 and 6...

Artificial insemination (AI) is an important technology for improving animal production. Through consistent use of AI, herd genetics can be advanced at a rapid rate. While AI is a technology that enables the dissemination of selected male genetics, embryo transfer (ET) is a technology that enables the dissemination of selected female genetics and, by using ET, frozen embryos can be moved around...

Since the development by Quinn and Burrows (1936) of a simple method of obtaining semen from and inseminating gallinaceous (chicken-like) birds, artificial insemination has made possible a number of studies on the physiology of reproduction and hybridization of these birds. An extension of the technique to the smaller birds, particularly to the pigeons and doves, holds promise as a tool for mor...
