Four fistulated Boer cross-bred bucks with 25 kg average body weight was used to test the effects of dietary treated rice straw supplemented with A. paniculata and O. stamineus on in-vivo rumen parameters and microbial population in goats. The study was conducted in 4 periods (4 x 4 Latin square design) where each period was for a duration of 22 d; 10 dof adaptation period 5 dof sampling and 7 dof change-over. The animals were fed once daily at 0800 (3 body weight) with 60 of urea-treated rice straw and 40 of one of four concentrate diets: T1-basal diet 1 A. paniculata T2-basal diet 1 O. stamineus T3-basal diet 0.5 of A. paniculata and 0.5 O. stamineus (AO) and T4-basal diet without supplementation of herbs. Clean water was provided ad libitum and the animals were individually penned. Rumen contents were sampled at 0 2 4 6 and 12 hafter the onset feeding and the pH was recorded. Rumen pH VFAs concentration of ammonia and microbial population in the rumen fluid were measured. The mean rumen pH was the highest (P0.05) at 2 h in T3 after the onset feeding while the mean concentration (mg/L) of ammonia in the rumen fluid was the lowest at 6 and 12 h in T2 (P0.05). The molar proportion of valerate was higher (P0.05) at 6 h in T1. Meanwhile the acetate to propionate ratio was affected by time where it was significantly higher at 12 h in T3. Significant reduction of total protozoa methanogens F. succinogens and R. albus number was observed in the herb-supplemented groups (P0.05). The results suggest that urea-treated rice straw with herbs supplementation can be fed to goats without impairing their performance. However further study could be done by increasing the supplementation of herbs in order to observe more effective results.

Abstract

Four fistulated Boer cross-bred bucks with 25 kg average body weight was used to test the effects of dietary treated rice straw supplemented with A. paniculata and O. stamineus on in-vivo rumen parameters and microbial population in goats. The study was conducted in 4 periods (4 x 4 Latin square design) where each period was for a duration of 22 d; 10 dof adaptation period 5 dof sampling and 7 dof change-over. The animals were fed once daily at 0800 (3 body weight) with 60 of urea-treated rice straw and 40 of one of four concentrate diets: T1-basal diet 1 A. paniculata T2-basal diet 1 O. stamineus T3-basal diet 0.5 of A. paniculata and 0.5 O. stamineus (AO) and T4-basal diet without supplementation of herbs. Clean water was provided ad libitum and the animals were individually penned. Rumen contents were sampled at 0 2 4 6 and 12 hafter the onset feeding and the pH was recorded. Rumen pH VFAs concentration of ammonia and microbial population in the rumen fluid were measured. The mean rumen pH was the highest (P0.05) at 2 h in T3 after the onset feeding while the mean concentration (mg/L) of ammonia in the rumen fluid was the lowest at 6 and 12 h in T2 (P0.05). The molar proportion of valerate was higher (P0.05) at 6 h in T1. Meanwhile the acetate to propionate ratio was affected by time where it was significantly higher at 12 h in T3. Significant reduction of total protozoa methanogens F. succinogens and R. albus number was observed in the herb-supplemented groups (P0.05). The results suggest that urea-treated rice straw with herbs supplementation can be fed to goats without impairing their performance. However further study could be done by increasing the supplementation of herbs in order to observe more effective results.
