Abstract:
The present study was conducted on lactating crossbred dairy cows with the objectives of evaluating the effect of mineral mixture supplementation on production performance and economics of small holder dairy farming under sub-humid ecosystem of Kolasib district of Mizoram. Experimental dairy cow’s was selected on mid phase of 2^nd stage of lactation for a period of 120 days. A total of sixty dairy cow’s (n=60) were divided into two groups viz., treatment (T₂-supplement of 50gm mineral mixture/cattle/day) and control (T₁-no supplementation) in a completely randomized designed. Analysis of data revealed that increased in milk yield (19.68%) by 1.23 litre day^-1 and number of insemination per conception leading to increased conception rate. However, significantly (p<0.05) reduce post partum estrus period and service period. The benefit-cost (B: C) ratio was recorded as 2.37 and 1.78 in the present study under intensive farmer management practices. Thus, supplementation of mineral mixture are beneficial and improved better results in augmenting milk yield and reproductive efficiency in crossbred dairy cow’s for enhancing more profitability, productivity and economically viable among smallholders’ dairy farmers in hilly regions.
