The experiment was conducted to evaluate the performance of beef heifers with average age of ten months and average initial weight of 200 kg, grazing cultivated annual temperate grasses mixtures supplemented with salt plus lasalocid or salt. Spread sowing ocurred on 04/21/95, being the area fertilized with 200 kg/ha of 05-30-15. Nitrogen fertilization in the form of urea (175 kg/ha of N) was subdivided in four applications. The establishment of the pasture occured from 04/21 to 06/08 and the experimental […]

Fourty Aberdeen Angus steers were used to evaluate the effects of monensin, soybean oil and nitrogen source (soybean meal or urea) on feedlot performance of steers fed 90% concentrate diets. The monensin decreased dry matter intake of soybean meal supplemented diets and decreased the body weight at 56 and 112 days. The soybean oil decreased the average daily gain from days 57 to 112 and 1 to 112. While, monensin showed a decreased on the average daily gain in these […]
