Females of Culex pipiens pallens are rarely inseminated at temperatures above 30 degrees C. Insemination and egg-hatching rates (F2) were examined in females of hybrids (F1) between Culex pipiens pipiens and Culex pipiens quinquefasciatus at 25 degrees C and 30 degrees C to examine temperature-dependent reproductive activity. Insemination rates were very high in hybrid females (F1) at 25 degree...

Assisted breeding technology (ART), including artificial insemination (AI), has the potential to advance the conservation and welfare of marsupials. Many of the challenges facing AI and ART for marsupials are shared with other wild species. However, the marsupial mode of reproduction and development also poses unique challenges and opportunities. For the vast majority of marsupials, there is a ...

Pote goats are kept by the rural community in Bangkalan Regency, Madura Island, Indonesia. Estrus symptoms usually unclear, causing low fertility. This study aimed to determine intracervical artificial insemination at early and mid-estrus on does. The 24 does were randomly divided into two groups estrous synchronization with PGF2α of 200 µg intramuscularly, twice injections 11 days intervals. T...

Introduction: This study aimed to perform routine seminal fluid analysis, sperm DNA fragmentation, and function tests at the chromatin maturation level evaluate pregnancy in patients passing intrauterine insemination before starting Intrauterine Insemination (IUI) method. Materials Methods: In this prospective study, 111 couples who underwent unexplained infertility were admitted Al-Farah IVF a...

Fertility data were collected every four weeks for 10 years from 40 herds of Holstein-Friesian dairy cattle. The data collected during 925 lactations from cows with cystic ovarian disease which were treated with 500 microg gonadorelin were compared with data from a control group of 13,869 normal lactations. The intervals between parturition and first insemination and between parturition and con...

Reproductive performance has an important effect on economic efficiency in dairy farms with short yearly periods of breeding. The individual factors affecting the outcome of an artificial insemination have been extensively researched in many univariate models. In this study, these factors are analysed in combination to create a comprehensive multivariate model of conception in Irish dairy cows....

Artificial insemination provides a method to inseminate a large number of females to a single sire that has been selected and proven to be an industry leader for economically relevant traits. Thus, genetic change in a herd can occur quickly through the use of artificial insemination. With natural service, herd bulls are also selected for economically relevant traits but are limited on the numbe...

Infertility has been linked to numerous factors in high producing dairy cattle in the last decades. The detection of estrus continues to present difficulties and, although progress has been made in regards to estrus synchronization and artificial insemination, the reproductive performance of dairy cows has not improved substantially. Moreover, in warm countries, summer heat stress is a major fa...

The techniques and-some of the events involved in the successful artificial insemination and incubation of Golden Eagles (Aquila chrysaetos) at Cornell University during 1972 are summarized. Cooperative insemination techniques (Berry, 1972)were used primarily, as opposed to the traditional forced, massage methods normally used for poultry (see Smyth, 1968). Cooperative insemination requires bir...
