Abstract

Twenty five F1 (Landrace x Yorkshire) sows parity of 2- 4 were used to determine the effect of catfish fat to late-pregnant and lactating sows on sow and their piglets’ performance. Sows were fed trial diets from 107 d of gestation until 21 d of lactation. Diets were: control without fish fat; 2% fish fat supplementation; 4% fish fat meal supplementation; 6 % fish fat meal supplementation; and 8 % 4% fish fat meal supplementation. The sow’s diet was made from the major ingredients including rice bran, corn meal, cassava meal and soy bean meal. Sows were fed 1.7 kg per day during gestation and 0.25 kg per piglet per day during lactation. Sows were were fed twice a day in the gestation and lactation period with diets containing 14.5 and 17.50 % of CP respectively. Calculated DE concentration in the diets was 13.0 –13.5 MJ per kg. Milk samples were obtained on d 3 and 20 of lactation. Milk from sows fed catfish fat increased n-3 fatty acids on d 3 and 20 of lactation. Results demonstrated that feeding catfish lard has significant effects on sow's milk yield, fatty acid profile and number and weight of weaned piglets.
