Dissertation note Artificial insemination (AT) in the poultry industry has considerable importance because of better results in fertility and hatchability. Increasing male utilization in artificial insemipation depends upon the optimum use of semen by suitable diluting media to increase the volume of ejaculate and to preserve fertility.

In the present study, the effect of sperm storage tubules secretions on percentage motility and extent of clumping of sperms was noticed. An optimum osmotic pressure 375 mOsm with pH 7.0 was used to preserve the cockerel's semen at 5°C. A total of 20 meat Breeder cockerels were randomly selected. After providing 10-days sexual rest, they were trained for semen collection by abdominal massage technique. Three birds failed to produce good quality semen. These birds were removed from the study.

Semen from seventeen Meat Breeder Cockerels was pooled. After
macroscopic evaluation, the pooled semen was divided into 4 groups.Group A was diluted with Modified Van Wambeke diluent with addition of sperm storage tubules secretions. Group B was diluted with the above diluent without SST secretions. Group C was diluted with saline solution with addition of SST secretions while group D was diluted with saline solution without SST secretions. These four groups were stabilized at 375 mOsm osmotic pressure in pH 7.0 and stored at 5°C. The diluted semen samples were examined for percentage motility and extent of clumping. After 72 hours of semen storage (5°C), group A showed significantly (P<0.05) higher motility as compared to groups B, C and D.

The extent of clumping was higher (P <0.05) in group D as compared to groups A, B and C. However, group A showed less (P <0.05) clumping upto 64 hours as compared to groups B, C and D.

The results of the present study suggested that at 375 mOsm, pH 7.0 the cockerels semen stored at 5°C diluted wiih Milk based extender and saline solution with addition to SST secretions proved to be suitable for short-term preservation of Meat Breeder Cockerel semen.
