Effect of Supplementation of Area Specific Mineral Mixture on Performance of Crossbred Cows with Reproductive Disorders in Kakatpur Block

The experiment was conducted to evaluate the effect of area specific mineral mixture on growth performance, blood parameters and reproductive efficiency in crossbred cows in Kakatpur block of Odisha. Forty crossbred animals were selected for the experiment and divided in to two equal groups. Among them number of anestrus animals and repeat breeder animals were 14 and 26, respectively. Therefore, each group had 7 anestrus and 13 repeat breeder animals. The animals in control group (T₁) were fed as per farmers’ practice while in group T₂, the animals were supplemented with area specific mineral mixture @ 50 g/d/animal for a period of 60 days. After the experiment, higher (P<0.05) ADG and BCS were observed in group T₂ (199.51±8.62 g/d and 3.93±0.02) as compared to group T₁ (143.66±8.50 g/d and 3.02±0.03). Blood glucose and Hb levels were higher (P<0.05) in group T₂ after the treatment. The serum mineral concentration increased (P<0.05) in group T₂. Percentage of animals having nonfunctional and sub-active ovaries was reduced leading to higher level of functional ovaries in group T₂. A higher percentage (55%) of animals in group T₂ conceived as compared to that of 15% in group T₁ at the end of the experiment. So, supplementation of area specific mineral mixture @ 50 g/d/animal resulted in higher ADG, BCS, blood glucose, Hb and also better reproductive health of the animals.
