REPRODUCTION PERFORMANCE OF RABBITS BY INCUBATED SEMEN WITH HEPARIN IN INDUSTRY RABBIT FARM

Abstract

The aim of the study was to evaluate the effect of incubation semen with heparin (25 000) in insemination dose on fertility rate of inseminated does, and on the number of all and liveborn young per litter. The experiment was realized in commercial farm. The farm was localized in areas of west Slovakia. The rabbit strain HYCOLE was used in experiment. Experimental does were inseminated with ID 0.5 cm3 with the concentrations of spermatzozoa from 40 to 50 x 10 -6 in cm3 . Experimental semen was incubated by heparin (0.06 microliter. per 1 inseminated dose) Control semen was incubated without heparin. In control part of experiment were used the same volume of ID, however without heparin. Incubation of semen dose with and without heparin was up to 1 hour. Rabbit does were inseminated after standard hormonal treatment. These studies demonstrate that heparin speed capacitation of rabbit sperm. The experimental group showed better result in conception rate (2.3 %), gravidity period and synchronisation of kindling.The number liveborn young rabbits per litter had statistically no significant (p > 0.05) effect. The data were evaluated by statistical method in statistic programme Microsoft Excel.
