Sow productivities of some important breeds in Thailand
1991
Neramit Sookmanee
Overall reproductive performance of the sows was evaluated. Crossbred sows produced from UK gave better reproductive performance than ROC line and Netherland significantly (P0.05) but Denmark, Belgium and ROC line were nonsignificantly different (P0.05). Effect of environment on reproductive performance of the sows was also evaluated. It is clearly indicated that number of parities had significant effects on farrowing index, average length of reproductive cycle and empty period (P0.05). Seasons have effects nonsignificantly (P0.05) on reproductive performance but the sows gave the highest performance in winter and the lowest performance in summer season.
