Twenty lactating Friesian cows and 20 lactating buffaloes with an average live body weight of 500 kg at 2-5 lactation seasonsafter the peak of lactation (60 days from parturition). Animals were fed summer rationconsisted of 40% concentrate feed mixture (CFM) + 40% corn silage (CS) + 20% rice straw (RS) (10 cows and 10 buffaloes) and winter ration consisted of 40% CFM + 40% fresh berseem (FB) + 20% RS (on DM basis) (10 cows and 10 buffaloes).Milk samples were taken from each cow and buffalo three times biweekly and prepared for minerals determination. The contents of Ca, K, Zn, Mn and Fe were higher in fresh berseem, while the contents of P, Mg, Na and Cu were higher in concentrate feed mixture, however, the lower contents of all minerals were detected in corn silage and rice straw. The contents and intake of all minerals were higher in winter ration containing fresh berseem than summer ration containing corn silage. The excretion of all minerals in feces and urine as well as absorption and retention increased significantly (P<0.05) with increasing dietary minerals intake. The concentrations of macro and micro-elements in milk of cows and buffaloes increased significantly (P<0.05) with increasing dietary minerals intake. The concentrations of Ca, P, Cu, Zn and Mn in milk of cows and buffaloes fed summer ration were lower than the normal values.
Keywords: Summer and winter rations, cows, buffaloes, milk, minerals.
