Abstract

For the improvement of genetic resources and their maintenance, new techniques of assisted reproductive technologies have been developed. Cryopreservation of semen, embryo transfer and artificial insemination in mammals are used, while in the avian technique of artificial insemination after semen cryopreservation is proved fruitful. By using this developed technique, the best fertility rate in chicken can be obtained by artificial insemination. In vitro cryopreservation can affect the motility, life of sperm, viability, fertilizing ability. From mammalian sperm cell, the avian sperm cell is different in shape, size having polyunsaturated fatty acid. The use of suitable cryo-protectants and semen extender can save the viability and morphology of sperm and can provide a better result of AI by a good fertility rate. A good fertility rate can be achieved by storing avian, turkey and chicken semen at 2-8°C, 4-8°C and 7-8°C. This paper will help to conclude the script of semen collection, cryopreservation, evaluation, diluents used to maintain sperm viability and fertility ratio. This review uniquely synthesizes recent advancements in poultry semen preservation, focusing on novel cryoprotectants, semen extenders, and optimization techniques. It integrates emerging practices and technologies to provide new insights into enhancing semen quality, fertility rates, and overall reproductive efficiency in poultry.
