Productivity of sows and growth of sucked piglets during one-phase and two-phase feeding them

Abstract

The article studied the reproductive qualities of sows and the growth of piglets under one-phase and two-phase feeding of suckling piglets. This study aimed to determine the dependence of the intensity of growth and survival of suckling piglets and feed consumption for feeding them using super-pre-starter feed during two-phase feeding of hybrid suckling piglets of Irish origin. In the conditions of the industrial complex, a comparison was made of the use of pre-starter feed traditional for the farm when it was fed to piglets from the seventh to the twenty-first day of life and the super-pre-starter, which was fed from the second to the fourteenth day, with subsequent transfer to the feed traditional for farms with pre-starter fodder. The advantages of the nests of piglets, which were used in the post-sucking period, were two-phase feeding from the second to the fourteenth day with super-pre-starter feed with a gradual transfer from the fourteenth to the eighteenth day of life to feeding with the pre-starter combined feed traditional for the farm and its subsequent use before weaning over analogs with single-phase feeding, which from the seventh to the on the twenty-first day, the traditional pre-starter feed was fed according to the survival of piglets before weaning by 5.7 % and as a result, their number at the time of weaning was 10.3 % greater and with practically the same individual weight of the weaned piglets, by 9.1 % the weight of their litter during this period, in comparison with their analogs, which used single-phase feeding from the seventh to the twenty-first day with traditional pre-starter feed. There was no significant difference in the individual weight of piglets at weaning and the average daily growth of piglets in the weaning period. It has been proven that during two-phase feeding, piglets ate 46.6 kg less of the entire range of feed for suckling piglets, which was 34.5 % less per litter and 49.5 % less per head. The comprehensive index of reproductive qualities of sows was better by 2.3 points or 5.4 % in sows whose nests of piglets were fed in two phases compared to animals whose offspring were fed in one phase.
