Analysis of Reproductive Traits of Giant Broiler Rabbit Lines

Peter Šmehýl, Veronika Petrovičová

Abstract


The aim of this study was to evaluate chosen reproductive traits of synthetic broiler rabbit line. The numbers of 7 reproductive traits were analysed. The synthetic broiler rabbit lines produced from local broiler population and Belgian Giant White sire rabbit were the object of analysis in our study. Number of total born young, lactation at 21st day, number of weaned (35), mortality and relative mortality, litter weight at birth and litter weight at weaning were analysed in experiment. The experiment was carry out in intensive farm conditions with controlled microclimate in wire cages, fed with balanced granulated mixture. Reproduction was provided by artificial insemination, heating and ovulation were stimulated by exogenous hormones. Kindlings were spontaneous and regulated lactation was applied. Following obtained values of analysed lines are presented in results. The average of total number of born in lines F1, B1, B2, B2.1 were 7,9 ; 9,08; 10,25 and 7,75 respectively. Weaning was carry out at the age of 35 days, and the average numbers of number of weaned young were: 6, 35; 7, 75; 8, 85; 5, 25. The mortality up to weaning reach average numbers 1, 55; 1, 08; 1, 5; 2, 5 pieces and 18, 42; 15, 13; 13,97; 33,72 %. The weights of litter at born reach values 240 -- 955 g. The weight of litter at weaning in each line was 4876, 25; 5940, 75; 7165; 4471, 88 g. Lactation at 21th day reaches average numbers 3257, 25; 6837, 5; 4511, 0; 3707, 5 g.
