Effect of frequency of collection on seminal characteristics of White Pekin duck

To determine an optimum frequency of semen collection, so as to improve the efficacy of artificial insemination techniques and selective breeding programmes in duck farming. Thirty two ejaculates were collected by abdominal massage method from two groups of drakes, with 10 in each, at one day and two day intervals respectively. Routine seminal attributes such as volume, colour, pH, spermatozoa concentration, number of spermatozoa per ejaculate, individual motility, live sperm percentage, total sperm abnormalities and time taken to reduce Methylene blue (MBRT) were studied for comparison of their values in one day and two days of interval of semen collection. Twenty female laying ducks maintained for examining the fertility percent were regularly inseminated with 0.1 mL of neat pooled semen for fertility test. The test of significance indicated a significant decrease (P
