Abstract: Uterine involution and onset of estrus in PO cows fed basal diets of rice straw and rice bran, supplemented with lamtoro leaf meal are interesting reproductive problems to study. Because what every breeder wants is that after parturition occurs, their livestock immediately experience uterine involution followed by estrus so that mating can take place. To address this problem, feed of a certain quality is very necessary. On the other hand, agricultural waste products such as rice straw and rice bran are widely available in the community but have low nutritional content so supplementation with lamtoro leaf meal would be an alternative solution. The research aims to study the process of uterine involution and estrus onset of PO cows fed basal feed of rice straw and rice bran, supplemented with lamtoro leaf meal. A total of 10 PO cows aged around 4.5 years in late pregnancy status were randomly grouped into two treatments, namely the group that received basal feed of rice straw and rice bran (R0) and the group that received basal feed of rice straw and rice bran, supplemented with lamtoro leaf meal ( R1). The research used experimental methods and the results were analyzed using one-way classification analysis of variance with the MINITAB 14 application. The results obtained showed that there was a significant difference (P<0.05) in the variables of uterine involution and estrus onset. Meanwhile, the symptoms of estrus, conception rate and pregnancy index were not significant (P>0.05). Dry matter consumption of feed was not significant (P>0.05), but there were significant differences in consumption of crude protein, TDN and crude fiber in the two treatments (P>0.05). It was concluded that supplementation of 50% lamtoro leaf flour in basal feed of rice straw and rice bran was quite effective in the occurrence of uterine involution and onset of estrus in PO cows.
