Effect of Supplementing Formaldehyde Treated Rape Seed Meal on Milk Production, Gross Milk Composition, Digestibility of Nutrients and Feed Conversion Efficiency in High Producing Crossbred Cows

Accepted: 13/06/2016 Abstract A study was undertaken to investigate the effect of supplementing formaldehyde treated rape seed meal on milk production, milk composition and feed conversion efficiency. Dietary supplementation of formaldehyde treated rape seed meal had no significant effect on the dry matter intake of cows from different groups. The average milk yield and 4% FCM yield were significantly (P<0.05) higher in T2 groups, as compared to T1 group. The average milk fat and total solids were significantly (P<0.05) higher in T2 group receiving formaldehyde treated rape seed meal, as compared to T1 group. The average daily CP intake and TDN intake in T1 and T2 groups were similar and satisfactory during lactation trial. Dry matter intake to produce one kg milk and 4% FCM was found to be 0.902 and 0.792kg and 0.846 and 0.727kg under T1 and T2, respectively at (P<0.05). The average daily returns over feed cost (Rs/cow) was 27.33 higher in cows yielding daily 20-21kg milk fed formaldehyde treated rapeseed meal (bypass protein) diet than the cows fed control diet.
