Effect of the housing technology on sow´s reproductive parameters
 KUČEROVÁ, Marie
The aim of this bachelor thesis was to write a review focused on the reproductive parameters of sows, the influences affecting them and the description of the housing technologies for sows. Another part of the thesis was to analyze the reproductive parameters of sows bred in the original technology (1,186 litters) and sows bred in a new technology (2, 240 litters). New technology ensures a better animal welfare. Sows housed in the original technology had 0.07 more all born piglets (14.40 resp. 14.33 pieces). In the number of piglets born alive was noted the difference of 0.20 piglet (12.82, resp. 13.02 pcs), in the number of surviving piglets was the difference of 1.36 piglet (10.31, respectively. 11.67 pcs), always in favour for the new technology. Sows housed in the new technology gave birth to 0.27 less stillborn piglets compare to those bred in the original technology (1.58 resp. 1.31 pcs). Differences in the number of surviving piglets and the number of stillborn piglets were confirmed as statistically highly significant.
