Effect of collection rhythm on spermatozoa and droplet concentration of rabbit semen

Thirty adult New Zealand White rabbit bucks were submitted to 3 collection rhythms: every day (D), every week (W), every 2 weeks (2W). The trial lasted 71 days and a total of 790 ejaculates were collected. Volume, concentration of spermatozoa, droplets and their dimensions were evaluated. Ejaculate volume and concentration of spermatozoa were the lowest (0.37±0.08 mL and 48.9±43.8x106 mL-1, respectively) when the samples were collected daily, whereas the ratio droplets/spermatozoa was the highest (6.4±3.3). The output of spermatozoa per week was the highest with W rhythm (173.4±105.3x106), followed by D (134.2±75.1x106) and by 2W (79.5±49.8x106 ) collection whereas the weekly output of droplets was the highest for D (810.2±615.7x106). In the following order of collection the spermatozoa concentration was similar in W and 2W while D showed a sharp decline of values after few collections. Semen droplets with respect to spermatozoa showed a more stable trend showing that droplets are able to respond better to high soliciting. Bucks submitted to an intensive rhythm were able to increase about 9-fold (respecting to W) the secretion of droplets by prostate glands. As a result, the ratio droplet/spermatozoa showed the highest values in daily collected semen (6.4±3.3). The repeatability of seminal traits showed that volume and spermatozoa concentration had the highest value followed by droplets, and ratio droplets/spermatozoa. In conclusion, it is possible to affirm that the collection rhythm, besides influencing the concentration of spermatozoa, also affects the rate of droplet production. A collection rhythm every 2 weeks was detrimental to both the spermatozoa and droplet output.World Rabbit Science. ICTA.
