The Meat Utilization of Rabbit Breed Czech Solver
PRAVDOVÁ, Lenka
This master's thesis focuses on the utilization of the Czech Solver, a Czech national rabbit breed, which is registered in The National Programme on Conservation of genetic resources of plants, animals and micro-organisms for Food and Agriculture. The Czech Solver was originally invented to be able to confirm or disprove the purebred origin of the tested animal. This feature is useful for breeders so that compensates for low meat performance breed. Fertility monitored breeding is less than the average fertility medium breeds, among that is the Czech Solver sorted, and significantly lower than the fertility of broiler rabbits. Surveyed individuals have achieved monthly weight gain sampler breeds of rabbits, but fattening period to 2.70 kg live weight ranged from an average of 105 days for semi-intensive rearing system in cages to 135 days at a traditional pens housing system farming, which is at least 27 days longer than the period of fattening broiler rabbits. Average growth rates were observed in the amount of 19.7 g in traditional breeding and 20.6 g in semi-intensive farming. Because the rabbits were slaughtered when reaching 2.70 kg live weight, were at abattoir analysis revealed no statistically significant differences between males and females or between traditional and semi-intensive farming. Slaughter analysis confirmed the breed Czech Solver average percentages of the intermediate part, fore and hind parts of the carcass and a higher proportion of kidney fat compared to other breeds of rabbits included in the genetic resources and compared with broiler breeds.
