If this feed loss could be effectively utilised by improving housing conditions, the productivity of pigs could be greatly improved. Improvement in housing conditions seems to be the cheapest alternative for improving efficiency of pig production in Nepalese situations. Improvements in nutrition of rearing gilts and lactating sows resulted in improvements of reproductive outputs in both station and village experiments. Farmers in the hills of Nepal do not rear boar and sows together due to lack of feed availability. Modified suckling management in the late...
