French field results (1985-2005) on factors affecting fertility of frozen stallion semen.
Results on procedures for freezing stallion semen and the subsequent fertility during 20 years are presented. The present system applied in French National Stud includes: (1) a freezing protocol (dilution in milk, centrifugation and addition of freezing extender (INRA82+egg yolk (2%, v/v)+glycerol (2.5%, v/v) at 22 degrees C, a moderate cooling rate to 4 degrees C and freezing at -60 degrees C/...
متن کاملEffect of Fresh and Frozen Semen on in vitro Fertilization and Subsequent Development of Goat Embryos
This study was undertaken to compare the efficiency of fresh and frozen-thawed buck semen on in vitro fertilization (IVF) of goat oocytes. Cumulus oocytes complexes (COCs) were collected by aspiration of 2-6 mm diameter follicles, which were obtained from slaughterhouse. Upon grading, only normal quality COCs were maturated in TCM-199 for 48 hours. The percentage of COCs reached to the M-II sta...
متن کاملCervical insemination of indigenous does with frozen-thawed goat semen during the non-breeding season
Introduction We received a request from the owner of a communal flock of indigenous goats in the Northern Province to inseminate some of his does with Gorno Altai semen. The only income he derived from this flock was through the sale of live goats at Christmas. He wanted to embark on a cross-breeding programme in an attempt to create an additional source of income from the fibre that would pote...
متن کاملSome Factors Affecting Freezing of Boar Semen in 5 ml Maxi-straws*
A series of experiments were conducted to determine the suitable freezing and thawing temperatures for the freezing of boar semen in 5 ml maxi-straws. The ultrastructure, in vitro fertilization (IVF) and artificial insemination (AI) of frozen-thawed semen were also be evaluated. The 5 cm freezing height gave the best results not only in post-thaw motility rate (54.00%), but also in normal acros...
متن کاملFactors affecting the reproductive performance of bitches: A prospective cohort study involving 1203 inseminations with fresh and frozen semen.
The aim of this prospective cohort study was to utilize multivariable statistical methods to identify factors that significantly affected whelping rate, litter size and gestation length in a large population of bitches of many different breeds, presented for routine breeding management. In addition, we aimed to determine the incidence of dystocia and the proportion of bitches undergoing a caesa...
