The aims were to evaluate the suitability of a non-commercial TRIS-lecithin (LC) extender and the effect of different concentrations of catalase (CAT) on motility, capacitation status (Chlortetracycline-assay) and zona pellucida (ZP) binding capacity of canine spermatozoa stored at +5 degrees C for 4 days. The sperm-rich fractions of the ejaculates of four stud dogs were divided into four aliqu...

This study was aimed to investigate the effects of omega-3, 6, 9 fatty acids on the characteristics of bovine chilled and frozen-thawed semen. For this purpose, oil containing different levels of omega-3, 6, 9 fatty acids were added to semen extender. To emulsify the oil in semen extender, polyethylene glycol (PEG) was added as a suitable solvent and the solution was finally sonicated. Five pro...

Artificial Insemination (AI) involves the introduction of sperm into the reproductive tract of the mare without natural mating. AI in the horse was first practiced long ago. Ancient Arabian texts describe how mares were successfully inseminated. In the late 18th Century, an Italian scientist took the idea up again. He performed a series of studies in which he placed stallion semen in the snow a...

Introduction The interest for canine semen preservation and artificial insemination (AI) is steadily increasing worldwide, yet comparatively few studies are published each year within this field, and it is particularly difficult to find data from artificial inseminations using fresh semen, or semen preserved according to various methods for chilling, or freezing and thawing, and also comparing ...

Tests were applied to extended, chilled boar semen to further define those factors associated with return to estrus in inseminated female pigs (sows and gilts). Females were each inseminated twice with the same batch of extended chilled single-sire semen that was concurrently assessed at the Charles Sturt University Andrology Laboratory (CSUAL) in Australia. Semen traits tested were pH, clump s...

the present study investigated the possibility of replacing salamon with modified shotor diluent (msd) and egg yolk (ey) with low density lipoprotein (ldl) for chilled storage of ram semen. good quality semen (>80% progressive forward motility (pfm) of sperm) from 3 fertile rams was collected using an artificial vagina and pooled for each experiment. low density lipoprotein was extracted from f...

Modern livestock breeding is basically dependent on the proper use of semen for artificial insemination of females and of other reproductive biotechnologies such as the production of embryos in vitro for embryo transfer. Both these techniques have made possible not only the wide dissemination of genetic material onto breeding populations but also enhanced the selection of best sires, owing to t...

The present study investigated the possibility of replacing salamon with modified shotor diluent (MSD) and egg yolk (EY) with low density lipoprotein (LDL) for chilled storage of ram semen. Good quality semen (>80% progressive forward motility (PFM) of sperm) from 3 fertile rams was collected using an artificial vagina and pooled for each experiment. Low density lipoprotein was extracted from f...

Preservation of ram semen has an impact on the exposure artificial conditions to spermatozoa which was followed by overproduction reactive oxygen species (ROS) and resulted in functional damages spermatozoa. This study aimed determine effect combination chicken, quail, duck egg yolks with green tea extract (GTE) quality Sapudi at 5°C storage. Ejaculates more than 70% motility were divided into ...
