Utilization of Ensiled Taro Mixed With Rice Wine by Product or Fish Meal Fed Basal Diet of Rice Bran on Reproduction and Piglet Performance in Sows in Cambodia

: In Cambodia, pig raising plays an important role as it provides meat and also increasing family income. Currently, researchers are trying to find the feeds that focus on using locally available natural resources as animal feeds can be used to reduce the cost of expensive feed on market such as soybean or fish meal. Based on that one experiment was designed and conducted at the campus of Svay Rieng University from 01 st April to 15 th September 2022, sited in NR 1, Sangkat Chek, Svay Rieng City, Svay Rieng Province. The aim of this experiment was to compare the feed intake of sows, the piglet performance in lactation, and the reproductive traits after weaning. Twelve sows were assigned according to Completely Randomized Design (CRD) within 3 treatments and 4 replications. The treatments of experiment were RW0, RWB20, and FM10. The results of the experiment were found that the total of feed intake in dry matter (DM) during pregnancy and lactation, were higher significantly different for the treatment of RWB20 (P < 0.01). There were no effects of all treatments on parameters in total litter size, mortality and total litter size live born of piglet performance at birth, except for total litter weight and mean live weight which was higher significantly different for RWB20 (P < 0.01). Non-significant different among the treatments on parameters in total litter size, mortality and mean piglet live weight at 21 days, except for total litter weight and litter weight change for RWB20 (P<0.01). There were higher significantly different for treatment of RWB20 in total litter size, total litter weight, litter weight change and mean piglet live weight at 45 days (P < 0.01). And there were no effects among the treatments on parameters in weaning to estrus, cycle of reproduction and number of litters per year in reproduction traits. However, length of pregnancy was higher significantly different for RWB20 (P < 0.01). It is concluded that a mixture of ensiled taro (10%) and rice wine by product (20%) were higher increased on feed intake of sows in pregnancy and lactation stages, higher increased on total litter size, total litter weight, litter weight change and mean piglet live weight in lactation period, and better effects on reproductive traits in weaning to estrus, cycle reproduction and number of litters per year. Using protein from a mixture of the ensiled taro and rice wine by product could successfully reduce the cost of pig feeds.
