| Dissertation note | In future, artificial insemination (AI) in poultry industry has a considerable importance because of the excellent results in fertility and hatchability. Increasing male utilisation in artificial insemination depends upon the optimum use of bids by increasing semen collection. The project was designed to scrutinise the effects of collection interval, testes weight and body weight on semen yield. A total of ten broiler breeder males (35 weeks of age) were randomly selected. After providing ten-day sexual rest these were trained for semen collection by abdominal message technique. In study I the effects of various frequencies of semen collection on semen characteristics were investigated. All birds being collected at 48hours, 24 hours and 12 hours intervals. In each interval five consecutive collections were examined for motility percentage, semen volume and sperm concentration. Out of ten one cock gave no semen through out the study and 2 birds did not yielded semen at 12 hours interval and were excluded from the study. No significant difference in collection intervals was established for percentage motility (P> 0.05), but semen collected at 12 hours interval was significantly lower than 24 hours interval in respect of semen volume and lower than 48 hours interval in respect of sperm concentration. Thus at 48 hours and 24 hours intervals we get significantly higher values of number of sperms per collection, number of motile sperms per collection and number of doses per collection than the values collected at 12 hours interval (P < 0.05). But difference for theses values at 48 and 24 hours collections intervals was non significant (P > 0.05). The total number of semen doses over a six-day period increased linearly and significantly as the frequency of collection increased from once every two day to twice daily. Daily semen collection was found to be more suitable for Al programme at broiler breeder farm. In study II daily semen output, paired testes weight and body weight were correlated. The semen output was found to be significantly correlated with testis weight (r =0.82) and body weight (r = 0.79), but no significant correlation was found between testis weight and body weight (r = 0.56). In biometrical examination the weight of left testis was found significantly heavier than right testis but in respect of testicular volume no significant difference was observed between the two sides. |
