  The existing practice of storing rice straw, routes of straw losses and problems related to livestock rearing in rural areas were studied in four selected villages of Mymensingh district of Bangladesh. The base line information on storage system of rice straw and livestock rearing problems were collected through PRA technique using a pre-designed questionnaire. From the survey it was identified that majority of the farmers stored rice straw traditionally making stack on the ground in unroofed condition and that caused considerable damage and losses of straw resulting shortage in the availability of rice straw for animals. Farmers reported that straw is lost in three stages - during harvesting, processing and storage condition. Harvesting loss was accounted for about 8 and 10% for Boro and T. aus straw, respectively. In wet season 25 and 23% of Boro and T. aus straw respectively, was lost during processing. About 18-20% of straw was lost during storage, which was mainly due to earthen evaporated gas, rat, termites, anjona (a reptile pest), poultry birds and excessive rainfall. In case of storage of rice straw the single most common solution for many problems as recommended by the farmers was to improve storage system. It may be concluded from the above results that traditional storage method leads to significant loss of rice straw resulting in feed shortage and impaired livestock productivity.

  The experiment was carried out to determine the nutritive value of different level of fermented rice straw as well as to detect the level of mycotoxin contamination and its transmission into cow`s milk. Rice straw was collected from selected area based on degree of fermentation i.e. high fermented, low fermented and unfermented rice straw. Similarly, milk samples were collected from cows fed rice straw of the same area. Results showed that, DM, CF and NFE were significantly (P<0.05) lower in high fermented rice straw compared to low and unfermented straw. The in vitro digestibility of OM of high fermented rice straw were significantly (P<0.01) lower than unfermented straw (40.69 vs. 41.55%). However, ME content of rice straw was similar (P>0.05) irrespective of level of fermentation. The effective degradability of DM for high fermented straw was significantly (P<0.05) lower than unfermented straw (13.03 vs. 19.26%). However, the effective degradability of CP of high fermented straw was significantly (P<0.05) higher than unfermented straw (17.10 vs. 10.83%). Chemical analysis of fermented and unfermented rice straw did not show detectable level of aflatoxin. However, milk samples collected from some area showed certain level of aflatoxin M1 (0.001 μg/kg to 0.006 μg/kg). These findings clearly show that, fermentation of rice straw due to dampness reduces its soluble nutrients, in vitro digestibility and degradation of DM in situ, however, increases the effective degradability of CP. Dampness also leads to the transmission of aflatoxin M1 from fermented straw to cow`s milk in low level.
