The reproductive performance of ten YorkshirexLandrace sows (initial age and live weight, eight months and 110 kg) from a mini-pig unit at the Swine Research Institute was evaluated during a three-year cycle (1996 to 1998). The sows were given a diet basedprocessed swill and sugar cane final molasses during the dry and gestating stages and a commercial concentrate (crude protein, 16%) during the lactating phase. There was no significant effect of treatment on the number of total born, total born alive and total weaned piglets and live weight at 21 days of age. Mean values for these traits were in 1996: 9.4, 8.8, 8.0 and 4.75 kg; in 1997: 9.1, 7.7, 7.2 and 5.12 kg, and in 1998:10.2, 9.0, 8.6, and 5.21 kg. There was a low significant effect of year (P0.05) for birth weight (1.37, 1.30 and 1.53 kg respectively) and a similar significant effect of year (P0.01) for weight at weaning (6.67, 7.97 and 7.66 kg respectively). The year of 1998 was considered as the best period of sow performance. Results from the current work showed that processed swill can account for more than 50% of the diet of sows with no negative influence in reproductive traits of the animals. Key words: sows, reproductive traits, processed swill, final molasses
