Lasalocid effects on dairy cows production of in a semi-intensive management system

AbstractThe effects of lasalocid over milk, milk fat content, live weight and body condition, were analysed on 18 “Mantiqueira” cows, 75 days after parturition in the begining of the trial. Cows were fed 1 kg concentrate mixture for each 2,5 kg of milk produced over the first 4.0 kg of milk, chopped elephant grass (Pennisetum purpureum, Napier var), and Brachiaria brizantha pasture. A randomized block design was used with 0, 200 or 300 mg of lasalocid/animal/day as treatments. The experimental period lasted 17 weeks, and first four weeks were used as an adaptation period to the ionophore. Lasalocid had no effects on milk or fat corrected milk production, but the 200 mg lasalocid group presented higher milk fat percentages (P < 0.05). The 200 and 300 mg lasalocid treatments groups showed lower (but not statistically) live weight gain related to control, when the data were
analysed as percentage of live weight. There was no variation on cows body condition.
