Abstract

The oxidative generation of utilisable energy is a more efficient process in epididymal spermatozoa than it is in ejaculated spermatozoa of the same species. The epididymal spermatozoa respire at a much slower rate than the ejaculated spermatozoa, although they display motility of comparable...

Abstract

After biochemical examination of the oviduct and infundibulum and of semen, a diluent was prepared containing inositol, glutamic acid, cysteine, a buffer and glucose. The motility of spermatozoa diluted 1: 3 in it and stored at 15° C remained good for up to 27 hr. Groups of 20 ♀♀ were inseminated...

Abstract

In this study, it was aimed to investigate the effect on principal sperm characteristics and fertility parameters of freezing of Saanen buck semen with skim milk powder extender containing different antioxidants. Ejaculates collected by artificial vagina from 4 Saanen bucks were used in the study....

Abstract

In mammals, the semen membrane contains a large number of unsaturated fatty acids, facilitating thus the lipid peroxidation in the presence of species reactive to oxygen. The consequence of this process is the reduction of the quality of the seminal material or even the death of the sperm cell. The ...

Abstract

The aim of the current study was to evaluate the effects of cysteine and ergothioneine on the post-thawed sperm parameters, lipid peroxidation and antioxidant activities. Semen samples from 5 mature Merino rams were used in the study. Semen samples, which were diluted with a Tris-based extender...

Abstract

The objectives of this study were to compare glycerol (G) and ethylene glycol (EG) at different concentrations and trehalose (T) or cysteine (C; with/without) in Tris extender for cryopreservation of bull semen. Twenty-four ejaculates obtained from three bulls were included in the study. Each...

Abstract

Supplementation of the semen extender with antioxidants did not produce any significant effect on CASA and progressive motilities and sperm motility characteristics, in comparison to the control group (P>0.05). For sperm acrosome and total abnormalities, TCM-199 supplemented with cysteine...

AbstractFull Text

Artificial insemination (AI) in livestock is used to optimize reproduction efficiency. Compared to other semen preservation methods, cryopreservation is an established industry used worldwide for performing AI. Adequate protocols for semen collection and freezing and then for the use in the AI are...

Abstract

We compared the effects of extenders of frozen-thawed semen on post-thaw sperm characteristics and the distribution of frozen-thawed spermatozoa in the female genital tract after fixed-timed deep intrauterine insemination (DIUI) in sows. Frozen semen samples were thawed and diluted in either...
