REPRODUCTION PERFORMANCE OF RABBITS BY INCUBATED SEMEN WITH HEPARIN IN INDUSTRY RABBIT FARM
Keywords:
rabbit, insemination, conception of rabbit, incubated by heparin, capacitation by heparinAbstract
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.
