Abstract

This experiment was carried out in five target villages in Svay Rieng province, Cambodia, from April 01, 2022 to August 15, 2022. The experiments have three objectives: (1) to compare the feed intake of sows during the pregnancy and lactation stages; (2) to compare the growth performance of piglets from birth to weaning; and (3) to compare the production cycle of sows after weaning. The experiment involved 15 sows using the Randomized Complete Block Design (RCBD) experimental design with three treatments and five replications. The treatments (T) were T1 (Control): Commercial feed 14% + Rice bran 43% + Broken rice 43%; T2 (RWB20): Ensiled Taro 16% + Rice wine by-product 20% + Concentrate feed 10% + Rice bran 53.5% + Premix plus salt 0.5%; and T3 (Traditional feed): Concentrate feed 5% + Kitchen residues 50% + Rice bran 40% + Broken rice 5%. The results of the experiment showed that the total feed intake in Dry Matter (DM) during the pregnancy period was significantly higher for T2 = 1,821 g/day, if compared to T1 = 1,344 g/day and T3 = 1,306 g/day. It was also found that the total feed intake in DM at the lactation period of T2 =2,238 g/day was significantly higher if compared with T1 = 1,681 g/day and T3 = 1,577 g/day. The number of piglets at the weaning stage of T2 = 10.7 heads/litter was significantly higher compared with T1 = 8.66 heads/litter size and T3 = 8 heads/litter size. The mean weight of piglets at the weaning day of T2 = 55.6 kg/litter size was significantly higher compared to T1 = 39.8 kg/litter size and T3 = 36.2 kg/litter size. For piglet mortality at the weaning of T1, T2, and T3 was not significantly different (p>0.05). The length of the reproduction cycle of sows after weaning of T2 = 174 days and T1 = 177 days was shorter, with a significant difference if compared to T3 = 181 days. In conclusion, the composition of feed containing Ensiled taro of 16%, Rice wine by-product of 20%, Concentrate feed of 10%, Rice bran of 53.5% and Premix plus salt of 0.5% could increase the feed intake of sows during the pregnancy and lactation stages, provide better growth of piglets at the weaning stage, and make the sows have a shorter reproduction cycle.
