Impact of the condition saw on the reproduction parameters.

The aim of the diploma thesis was to analyse the saw body condition and to judge the impact of the condition on the reproduction parameters. The body condition effect on the live weight of piglets in the litter from the birth to the weaning was not proved. The sows classed into the fasting condition had longer farrowing interval than saws classed into the breeding condition. The level of decrease the live weight of the sows during the lactation did not dramatically influenced the number of piglets in the litter. The highest piglet looses from farrowing to weaning were found in the first three litters. For optimal breeding conditions is necessary to keep the sows in condition closest to the breeding (optimal) condition
