EFFECTS OF TOTAL MIXED RATION (TMR) DIFFER BETWEEN PROGRESSIVE AND LESS PROGRESSIVE FARMERS

Abstract

A study was conducted with the objective to determine the effects of Total Mixed Ration (TMR) on milk yield and constituents. Feeding experiment was conducted at a progressive dairy farm in Phuntsholing and two less progressive farms in Sarpang. All cows in individual farms received same amount of TMR in addition to their normal diet. Milk yield was recorded before and after TMR feeding. Milk samples from all experiment animals were collected and analyzed weekly for nutrient composition. Feeding trial lasted for 21 days, including two weeks of adaptation period. There was no significant difference in milk production before and after feeding TMR at progressive dairy farm. However, milk production, fat, SNF and protein contents were significantly higher after TMR feeding at less progressive farms. The study findings suggest TMR as a healthy feeding strategy to improve nutritional status and enhance productivity of dairy cows. Where local feed ingredients are abundant, TMR feeding should be recommended for the dairy farms with poor feeding practices. The study also suggests TMR not to be recommended for commercial dairy farms with improved feeding practices. Formulation of TMR should be carried out under the supervision of trained extension personnel.
