Description

The dry matter and protein degradation rate of some tropical Bangladeshi forages were determined by using the nylon bag technique. The different forages and concentrates were dhancha (Sesbania aculeata), matikalie (Phaseolus mungo), ipil ipil (Leucaena) and water hyacinths (Echhomia crassipes), mustard oil cake and fish meal as control. A slow dry matter disappearance (from nylon bags) was observed for fish meal followed by ipil ipil and water hyacinths. It was also observed that the dry matter from mustard oil cake disappeard very rapidly, while the dhancha and matikalie formed intermediate of the above mentioned feed stuff. Results confirm that concentrates and forages can vary substantially the rate of dry matter disappearance. Similar pattern of protein disappearance was also observed with feed samples. Fish meal, ipil ipil, water hyacinths, dhancha, matikalie exhibited a significant, slow rate of degradation of protein as compared with oil cake. The calculated effective protein degradability was 62%, 60%, 42%, 58%, 91 % , and 22% at an outflow rate of 4.4% per hour from the rumen with dhancha, matikalie, ipil ipil, water hyacinths, mustard oil cake and fish meal respectively. It was concluded that the degradability of protein from oil cake was found to be extensive compared with fish meal and legume forages and water hyacinths.
