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...
متن کاملStorage of ram semen.
Storage of ram semen in liquid and frozen state, the diluents used for both methods, processing, cooling, freezing and thawing of semen are reviewed. Factors influencing the fertility of stored semen and methods used for improvement are discussed, and fertility results of long-term frozen stored ram semen are also given.
متن کاملEffect of vitamins C or E supplementation to Tris diluent on the semen quality of Awassi rams preserved at 5 ˚C
The present study was aimed to test the efficacy of adding vitamins C or E to Tris-fructose-egg yolk diluent to increase Awassi ram sperm storage period at 5 ˚C. Semen samples from six mature Awassi rams were used in this study. The semen samples were diluted by Tris-glucose-egg yolk. Diluted semen sample was divided into three parts. The first part was added with 0.9 mg mL-1 vitamin...
متن کاملImplications of the pH and temperature of diluted, cooled boar semen on fresh and frozen-thawed sperm motility characteristics.
Boar semen is typically collected, diluted and cooled for AI use over numerous days, or frozen immediately after shipping to capable laboratories. The storage temperature and pH of the diluted, cooled boar semen could influence the fertility of boar sperm. Therefore, the purpose of this study was to determine the effects of pH and storage temperature on fresh and frozen-thawed boar sperm motili...
متن کاملPlasmalogen in ram semen, and its role in sperm metabolism.
Whole semen can be stored successfully under both aerobic and anaerobic conditions, owing to the presence of glycolysable carbohydrate in the seminal plasma. However, if mammalian spermatozoa are separated from the seminal plasma by centrifuging and washing, they can maintain their motility only in the presence of oxygen. From this it has been inferred that when spermatozoa are deprived of fruc...
