Abstract/ Executive Summary:

The study was conducted with the objectives to determine the nutritive value, intake and digestibility of mungbean residues as silage in bull. Mungbean residues were collected, chopped and preserved as silage at BLRI research farm. Twelve Pabna growing bulls were divided into two equal groups, one of them was fed with rice straw ad lib (Control) and the other with mungbean silage (Treatment). After adjusting the animals to the diets for 20 days initially, the animals were transferred to the metabolic crates for 7 days. It reveals that the DM matter intake (kg/day) of mungbean residues silage was significantly (p<0.01) higher compared to straw group. Similarly, CP intake from mungbean residues silage was 560 ± 12.35 g/day , whereas CP from straw was significantly lower (190± 0.00 g/d). The digestibility of DM, OM, CP, ADF was significantly higher (p<0.01) in mungbean residues silage compared to straw. Calcium and P intake from mungbean residues silage were 12.91± 0.23 and 16.88± 0.31 g/day, respectively. It was noted that per cent Ca and P outgo in the feces was significantly (p<0.01) higher in straw (55.77% compared to mungbean silage (23.37%). Based on the above findings, it can be concluded that the utilization of mungbean plant biomass as a cattle feed may be one of the option to reduce feed scarcity in the country.

Commodity: Cattle

Objectives:

To determine the nutritive value, intake and digestibility of mungbean residues as silage in bull

Methodology:

Mungbean residues were collected, processed and ensiled with molasses and preserved for 3 months as silage. After 3 months, it was used for intake and digestibility trial and nutritive evaluation. Twelve Pabna growing bulls were divided into two equal groups, one of them was fed with rice straw ad lib (Control) and the other with mungbean silage (Treatment). Adjusting the animals to the diets for 20 days initially, the animals were transferred to the metabolic crates for collection of feed residues, feces and urine. Samples were collected as per standard procedures and stored for further analysis. Nutritive components of feed samples were analyzed. Calcium contents of feed and feces samples were analyzed using Atomic Absorption Spectrometry (Atomic Absorption Spectrophotometer, MODEL 210 VGP, Buck scientific) and phosphorus was determined using a Colorimetric (T60 spectrophotometer, THURAMED. Louisville, KY. USA). All the collected data were analyzed through SPSS package in computer and T-test was used to determine the significance of treatment means.
