Eighteen selected pregnant gilts were randomly divided into two groups of 9 each. In control group the piglets were weaned at 56 days. Intreatment group heavier piglets (> 1.2 kg body at birth) were weaned at 28 days and remaining lighter piglets were weaned at 42 days. Data pertaining to reproductive traits, body weight changes and feed intake were observed and recorded. The result indicate that weaning-to-oes- trus interval was significantly (P<0.05) shorter in treatment group (5.17: 0.21 days) compared to control group (8.68 i 0.42 days). Significant difference has been observed in the body weight loss from farrowing to weaning. The body weight loss in treatment and control group were 20.38: 3.65 and 30.53: 3.18 kg respectively Total feed cost per sow was significantly (P<0.05) lower in treatment group (Rs.1281.42i 112.47) compared to control group (Rs.2022.93i 185.64). There was no signifi- cant difference in the average feed intake of gilts. In conclusion, the split weaning system has reduced the body weight loss, shortened weaning—to-estrus interval and reduce feed cost per gilt. The split weaning system may increase the frequency of farrowings and reduce the maintenance cost of sowsenVeterinary ScienceArticle
