      abstract = {Pig-farming has a long tradition in Hungary, most  significantly within the Alföld region. In my analysis I  studied the lifespan of
sows in two nucleus pig herds on  the Great Plain, also examining the probability of the  occurrence of different reasons for culling. During
my  research I collected data (from 2001 to 2010) relating to  more than 10,000 sows from the farms conducting a breeding  programme and I
searched for the answer to the question of  whether can I find a significant difference in the lifespan  of sows with the same feeding and the
same genotype if the  floor type of farms is different (Herd A has a solid floor  with straw and Herd B has a slatted floor). Regarding the  reasons
for culling ANOVA was used to investigate mean  differences in logarithms of the lifespan of sows in each  herd. Between the herds the seven
most common culling  reasons were estimated with the Kaplan-Meier method and the  significant difference was demonstrated with the  logrank
test. The results of the log-rank test showed that  there was a significant difference in leg problems as a  cause of culling and deaths (p <
0.05) between the two  farms, which is the consequence of different floor types.},
