Quality of napier bajra hybrid silage prepared in bunker silo without additives

摘要

Silage was prepared from napier bajra hybrid fodder in bunker silo without additives in 45 days. For the test of palatability of silage, six dry Deoni cows were divided into two groups (control group and treatment group) and offered rations with or without napier bajra hybrid silage along with concentrate mixture and jowar straw for a period of 45 days to fulfill their nutrient requirements. The colour of the napier bajra hybrid silage was greenish yellow to brownish with vinegar smell and pleasing taste. The silage was firm in texture, without mould growth and acidic (pH 4.0) in nature. The dry matter content of the fodder did not changed (P>0.05) during ensiling. The CP% and NFE% decreased (P<0.05) and CF% increased (P<0.05) during ensiling. The DM intake of the cow fed silage was 3.40 kg/ day, which was 13.61 kg on fresh basis. The total DM intake (kg/day) in the treatment group (7.96) was lower (P0.05) than the control group (8.59). However, the DM intake (kg/day) as percent body weight was similar (P>0.05) in both groups and ranged between 2.52 to 2.72. There was no change (P>0.05) in the body weight of the animals and all the animals were in healthy conditions. It was concluded that silage prepared in bunker silo from napier bajra hybrid green fodder without any additives is well accepted by dairy animals.
