Abstract

The aim of this study was to evaluate selected reproductive parameters the sows and the piglet losses from birth to weaning. Monitored parameters were evaluated for two commercial programs. Experimental population consisted of 90 sows (45 in commercial program A and 45 in commercial program B). The total number of born piglets from sows in commercial program A reached 15.96 against 15.42 piglets in commercial program B. Total number of live-born piglets from sows in commercial program A reached 14.82 against 14.43 piglets in commercial program B. Sows in commercial program A had 1.14 stillborn piglets per litter while those in commercial program B had 0.99 stillborn piglets. The result of experiment were 13.11 reared piglets per litter in commercial program A and 13.64 reared piglets per litter in commercial program B. In the commercial program A the loss amounted 1.81 piglets against 0.79 piglets in commercial program B. The percentage of loss of piglets was 12.21 in commercial program A and 5.47 in commercial program B. Values of selected reproductive parameters found in the experiment within both programs can be considered very competitive.
