Sažetak
Litters from high prolific sows are characterised by the variability of birth weights of piglets and higher frequency of light and avital piglets, which can negatively affect production results of piglets in following production stages. The aim of the paper was to determine effect of birth weights of piglets from farm with high prolific sows on average daily gains of piglets in lactation and nursery phase. The study included 296 piglets from 25 sows of Pen Ar Lan hybrid lines farrowed between December 2014 and January 2015. The focal variable was average daily gain of piglets from birth to the end of nursery phase. Birth weight had significant effect on daily gains of piglets during lactation and nursery phase. Piglets from the classes with lower birth weights had significantly lower average daily gains in analysed period compared to piglets with higher birth weights. Results obtained in this study show the necessity of reducing the number of avital piglets with low birth weights in order to enable higher survival rate and optimal growth rate of piglets from litters of high prolific sows.
