Kit’s quartiles distribution is a useful tool for equalisation practice.Does parity order influences litter size and born-alive weight.Based on these results, we suggest for the commercial genetic centres to equalise the litters according to the birth weight, by dividing the population into quartiles and rearing kits with light birth weight in smaller litters and those with heavier birth weight in larger litters. Litter homogenisation is crucial to ensure a proportionate share of milk, more equal growth, and better productive performances. The results confirmed that does parity order influences litter size and born-alive weight, but also the intra- and inter-litter homogenisation. All these litter homogeneity evaluation parameters appeared interesting in describing differences between parity orders. No significant effects on still-born numbers and mortality rates were evidenced. These parameters decreased in greater parity orders. In this study, the 1st and 6th parity order had, respectively, the lowest and highest values in litter size (8.96 vs 12.39, n), born-alive (8.36 vs 12.22, n), litter weight (456.4 g vs 719.8, g), born-alive weight, and quartiles’ homogeneity. #Iunit weight of kindling trialThis trial aimed to consider the litter homogeneity weight at birth, both within each litter and in the whole population, in order to suggest new proper within-litter homogenisation parameters. Thus, it is important to study individual newborn and intra-litter homogeneity parameters. Birth weight and little size are valuable parameters as related to mortality and weaning weight. In rabbits’ reproductive performance, litter size, birth weight, growth, and mortality rate are among the most important indicators to define the productive potential and they are associated with parity order. ![]()
