Abstract

Millions or billions of sperm are deposited by artificial insemination or natural mating into the cow reproductive tract but only a few arrive at the site of fertilization and only one fertilizes an oocyte. The remarkable journey that successful sperm take to reach an oocyte is long and tortuous,...

Abstract

Optimization of artificial insemination (AI) for pig production and evaluation of the fertilizing capacity of boar semen are highly related. Field studies have demonstrated significant variation in semen quality and fertility. The semen quality of boars is primarily affected by breed and season. AI ...

Among cultured freshwater fish, Nile tilapia Oreochromis niloticus is considered as one of the most important species. With the current intensive culture, reproduction of Nile tilapia takes place in captivity where numbers of male and female broodstocks spawn independently in the mating tank. The ...

Abstract

The Indochinese leopard (Panthera pardus delacouri) population, included in CITES Appendix I, has been declining for decades. Proper gamete preservation condition is critical for breeding programme management using artificial insemination or in vitro fertilization (IVF). The present study aimed at...

Abstract

Fertilization involves a complex process and requires many sperm attributes for its success. There is great variation in the semen of different bulls and batch, which causes an oscillation in fertility potential. The use in TAI of semen batch with reduced fertility potential causes a great impact...

AbstractFull Text

Plasminogen-plasmin system has been related to different process of the male reproductive function, as spermatogenesis, sperm capacitation, and fertilization. However, the specific role and importance of uPA for the pig male reproductive function is not well known. The concentration of uPA in...

Abstract

In a split-ejaculate study, semen from 5 boars was frozen in pellets and straws, thawed in Beltsville thawing solution and diluted in OLEP diluent before surgical insemination into the uteri of 12 gilts. Each gilt received pelleted semen in one uterine horn and semen from a straw in the other. For...

Abstract

40 ejaculates from rams of 3 breeds were diluted and packed in glass ampoules or in Cassou straws, and were stored for up to 10 days. Semen in straws generally showed better motility, thermal resistance and fertilising ability in tests after 24-240 h of storage, in comparison with semen in ampoules.

Abstract

For ejaculates from New Zealand White (NZW), California White (CW) and Black and Tan (BT) males , sperm velocity averaged 44.7, 52.7 and 52.9 mu m/s resp. (differences significant). The fructose concentration of the semen also differed significantly among the 3 breeds. When NZW females were exposed ...

Abstract

Semen collected weekly from 13 males (Small Russian, New Zealand White and Californian White) was examined, and ejaculates in which more than or equal to 75% of spermatozoa had the highest motility score (on a points scale) were pooled. Two methods of dilution were used: (1) a single dilution (1:5) ...
