The objective was to study the effect of the monensin on milk yield and milk composition, somatic cell count, body condition score, serum parameters and reproductive aspects high producing Holstein cows in early lactation. Fourty-four cows with daily milk yield of the 33.44 ± 4.93 liter of milk were assigned to a completely randomized design with two treatments: control (C) and other with controlled released monesin capsule with eficacy of 100 days (300 mg/cow/day). The individual administration of the monensin […]

The objectives of this trial were to evaluate the effect of replacing corn meal with coffee hulls or soyhulls on intake and apparent digestibility of nutrients, milk yield and composition, and body weight (BW) change in lactating dairy cows. Twelve purebred and crossbred Holstein cows were assigned to three replicated 4 ´ 4 Latin squares. Diets were isonitrogeneous (14% of CP, DM basis) and control diet contained 60% corn silage plus 40%concentrate. Three sugarcane based diets with 60% concentrate were […]
