Esterified glucomannan improves aflatoxin-induced damage of sperm parameters during liquid storage of ram semen at 5°C.

The aim of the present work was to study the effects of aflatoxin (AF) on sperm parameters in rams, and to determine the protective efficiency of esterified glucomannan (EG) co-administered with AF up to 96 h of the liquid storage of ram semen at 5°C. Thirty-two Merino rams (12-14 months old) were used. The animals were examined for their general health status.

Protective effect of esterified glucomannan on aflatoxin-induced changes in testicular function, sperm quality, and seminal plasma biochemistry in rams.

The aim of this study was to determine the effect of aflatoxin (AF) on spermatologic, biochemical, and testis parameters in rams, and the protective efficiency of esterified glucomannan (EG) co-administered with AF. Thirty-two Merino rams (12-14 months old) were used. The experimental design consisted of four dietary treatments.

Raffinose and hypotaurine improve the post-thawed Merino ram sperm parameters.

The aim of this study was to determine the effects of raffinose and hypotaurine on sperm parameters after the freeze-thawing of Merino ram sperm. Totally 40 ejaculates of five Merino ram were used in the study. Semen samples, which were diluted with a Tris-based extender containing 10mM raffinose, 5mM hypotaurine, 5mM raffinose +2.

Methionine supplementation improves ram sperm parameters during liquid storage at 5°C.

The aim of this study was to investigate the effects of methionine and lipoic acid on ram sperm parameters during liquid storage (5 °C). Ejaculates collected from five Merino rams were pooled at 37 °C. Each pooled ejaculate was divided into five equal aliquots and diluted (37 °C) with five extenders, one of which was without additives, two of which contained methionine at two different doses, and the other two of which contained lipoic acid at two different doses.

Effects of dithioerythritol on ram semen after the freeze-thawing process.

The aim of this study was to evaluate the effects of dithioerythritol added to cryopreservation extender on the post-thawed sperm parameters, lipid peroxidation and antioxidant activities of Merino ram sperm. Semen samples from 5 mature Merino rams (1 and 2 years of age) were used in the study. Semen samples, which were diluted with a Tris-based extender containing 0.

Effects of cysteine and ergothioneine on post-thawed Merino ram sperm and biochemical parameters.

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 containing l-Cysteine and l-(+)-Ergothioneine and no antioxidant (control), were cooled to 5°C and frozen in 0.

Effects of antioxidants on post-thawed bovine sperm and oxidative stress parameters: antioxidants protect DNA integrity against cryodamage.

This study was conducted to determine the effects of methionine, inositol and carnitine on sperm (motility, abnormality, DNA integrity and in vivo fertility) and oxidative stress parameters (lipid peroxidation, total glutathione and antioxidant potential levels) of bovine semen after the freeze-thawing process. Nine ejaculates, collected with the aid of an artificial vagina twice a week from each Simmental bovine, were included in the study. Each ejaculate, splitted into seven equal groups and diluted in Tris-based extender containing methionine (2.

Influence of methionine and dithioerythritol on sperm motility, lipid peroxidation and antioxidant capacities during liquid storage of ram semen.

The aim of this study was to investigate the effects of methionine and dithioerythritol, added to the Tris extender, on ram sperm motility and LPO (lipid peroxidation) and antioxidant capacities during liquid storage up to 72 h at 5°C. Ejaculates collected from five Merino rams, were evaluated and pooled at 37°C. This study included two experiments.

Effects of hypotaurine, cysteamine and aminoacids solution on post-thaw microscopic and oxidative stress parameters of Angora goat semen.

This study was conducted to determine the effects of cysteamine, hypotaurine and aminoacids solution (BME) on standard semen parameters, lipid peroxidation and antioxidant activities of Angora goat semen after the freeze-thawing process. Ejaculates collected from four Angora goats were evaluated and pooled at 37 degrees C. Semen samples, which were diluted with a Tris-based extender containing the antioxidants hypotaurine (5 mM) and cysteamine (5 mM), and an aminoacid solution (13%), and an extender containing no antioxidants (control), were cooled to 5 degrees C and frozen in 0.
