Effect of supplementation of minerals and enzymes on service period and postpartum plasma minerals profile in crossbred cows

Twenty recently calved healthy triple crossbred (HF x J x K) cows were divided randomly into four groups each of five animals from the day of calving to observe the effect of supplementation of minerals + proteins-vitamins (Nutri-sacc power pack, Vetcare) and enzymes (Neozyme RU, Biocon India Ltd) on service period and fortnightly plasma profile of macro-micro minerals up to 105 days postpartum. The animals of Group-I (T0) served as control; of Group-II (T1) were given nutri-sacc powder @100 g/d/h; while animals of Group-III (T2) and Group IV (T3) received neozyme supplementation @ 750 and 1000 g per ton of concentrate mixture, which was fed @ 1 kg for every 3 kg milk. The supplementation of minerals and enzymes did not influence service period significantly (147±13.69 days). The pooled plasma calcium, inorganic phosphorus and magnesium concentrations were 10.29±0.11, 4.43±0.10 and 3.40±0.09 mg %, respectively. Significant (P
