СІВЯС – ефективний метод оцінки та відбору високопродуктивних свиноматок за відтворювальними якостями

Abstract

Мета роботи – дослідити відтворювальні якості свиноматок та оцінити їх племінну цінність з за селекційним індексом відтворювальних якостей свиноматки (СІВЯС) та розрахувати економічну ефективність результатів досліджень. The paper presents the results of the study of the reproductive qualities of sows of different breeding value according to the selection index of the reproductive qualities of the sow (SIRQS) and the calculation of the economic efficiency of their use. It was established that the sows of the large white breed of the controlled population in terms of fertility and litter weight at the time of weaning at the age of 60 days belong to the I class and the "elite" class. The maximum indicators of multiple fecundity (13.1 ± 0.19 heads), weight of the nest at birth (15.4 ± 0.19 kg), weight of the nest at the time of weaning at the age of 32 days (84.2 ± 1.03 kg) and selection index of reproductive qualities of the sow (102.87 ± 0.985 points) characterize the sows of the experimental group I. The difference between animals of the II and I groups is 21.46 % in terms of high fertility, index of evenness (homogeneity) of the sow's nest, according to the live weight of piglets at the time of their birth and survival. The use of sows of the I experimental group provides additional production at the level of +8.90 %, and its cost is equal to +330.22 UAH / head / farrowing.
