The influence of inbriding on viability, preservation and anatomy of the liver of Californian breed of rabbits

The influence of inbreeding on viability, safety and manifestation of anomaly of liver structure in the form of slit-like spaces in rabbits of the Californian breed was studied. The studies were conducted on the basis of rabbit farm "Bratets Krolik" in the period from May 2017 to March 2018. The analysis of obtained results showed that the birth rate of rabbits, regardless of the forms of inbreeding, was within the physiological and pedigree norm. The viability of rabbits aged 1 to 95 days correlated withthe degree of inbreeding animals: 100 % preservation was observed in the control group, the highest mortality rate was recorded in experimental group with a close degree of inbreeding I-II - 84.3 %. In experimental group II-II with the closest relatedness of individuals in parental pairs, the largest number of stillborn and baby rabbits with congenital anomalies were recorded - 75 % of all births of rabbits with deformities and 47.4 % of cases of underdeveloped embryos...
