The Fertilizing Capacity of Diluted Chicken Semen

Fertilizing ability of turkey semen diluted with simple sugar-based extenders after cooled storage

It is now possible to store turkey semen for 4 to 24 h without appreciable loss in fertility and hatchability. Optimum conditions for 24 or 48 h storage have not been fully determined. Development of new storage media, allowing the insemination of very low numbers of spermatozoa, may provide interesting possibilities regarding the use of superior sires. This study was conducted to evaluate effe...

Fertilizing capacity of the cryptorchid rat.

Rats were surgically made bilaterally cryptorchid and after 4-8 days the testes were returned to the scrotum. After 70 days fertility was tested by pairing with females. Fertility was restored in 5/6 rats with testes cryptorchid for 4 or 5 days, but only 2/9 were fertile when the duration of cryptorchidism was 6-8 days. The sterility was due to irreversible degeneration of the spermatogonial st...

Analysis of in vitro fertilizing capacity to evaluate the freezing procedures of boar semen and to predict the subsequent fertility.

A porcine in vitro fertilization (IVF) system and seminal quality parameters of frozen-thawed boar semen were used to assess the effectiveness of two different thawing rates of frozen boar semen, and to address the question of whether differences between fertility of ejaculates could be predicted in a limited field trial. In the first experiment, two thawing procedures were analysed (37 degrees...
