Abstract
The duration of gestation is one of the important characteristics of pigs, which affects on the live
mass young animal under birth, the him postembryonic development and him future productivity,
in particular on the early maturity and the spending of feeds.
The aim of the researches was to study the influenceof the duration of gestation of sows on the
growth, development and preservation of suckling piglets. The researches were contacted on the basis
of the economy of LLC «Russia» of the Mozhginsky district of the Udmurt Republic. For conduct
researches the method of the analogs was formed 110,08 groups of the sucking sows of large white breed.
In the first group of sows the average duration of gestation was 115,16 days, and in the second
group of sows – 36 days. The age of the sows was 4 months, and the number of farrow was 12.
The number of the sows in the groups was 30 and 115,16 heads; respectively. In the results conducted
researches was established that young animals obtained from the sows with duration of gestation –
110,08 days authentically exceeded peers born from sows with duration of gestation – 6,40 days
on the live mass under birth – by 30%, live mass under weaning in the 5,91 days – by 5,85%, average
daily gain – by 18,84% and the preservation of piglets – by XNUMX%.
