- The aim of this study was to investigate rumen microbial protein synthesis through purine derivatives excretion on Bligon goat fed with fermented tofu by-product as main component of diet supplemented with NaHCO3 as buffer. Twelve female Bligon goats, 25 kg body weight were placed individually on metabolism cages and divided into 3 groups (4 goats each). All goats received forages and fermented concentrate mixed diet. The ratio of forages: concentrate was 70:30. Forages consisted of native grass and peanut straw (1:1), while rice bran and pollard were used as concentrate, and industrial tofu by-product as main concentrate. Diets were supplemented with NaHCO3 buffer at 0%; 1,5%, and 3% of total ration (as fed). The experiment was done for 37 days which includes feeding adaptation for 30 days. At the last 7 days, feed residue, faeces, and also urine were collected everyday for chemical analysis. Moreover, urine was collected as 24 hours for total excretions of allantoin, uric acid, xanthin, and hypoxanthin analyses. All data were analyzed using analysis of variance with one way design followed by Duncan's Multiple Range Test. Suplementation of NaHCO3 significantly increased concentration of purin derivatives and estimated microbial protein synthesis (EMNS). The amount of purine derivatives (μmol/unit/day) on each treatment P0, P1, P2 were 1926,33; 2609,78; 2430,95 with EMNS (g N/d) were 1,8; 2,01; and 2,04. Total of purine derivatives excretion based on body weight metabolism, digestible organic matter on rumen (DOMR), and EMNS/DOMR (efficiency of microbial protein synthesis) were not affected by NaHCO3 supplementation. It can be concluded that supplementation of NaHCO3 1,5% on fermented industrial tofu by-product increased concentration of purine derivatives, total excretion of purine derivatives, and EMNS on Bligon goat although it couldn’t increase efficiency of microbial protein synthesis.
