Performance of crossbred Nelore steers on non‐irrigated and irrigated Brachiaria brizantha cvMG 5 in rotational grazing system

摘要

Brazil presents an enormous potential for cattle production on pasture.However,water is one of the main determinative factors of the growth of crops ; the irregularities of rainfall regime during the year are restrictive to the agricultural development of tropical countries such as Brazil.Thus,the irrigation has been one of the techniques most widely used in agriculture to obtain high yield (Drumond & Fernandes,2001).It was aimed,through this work ; to evaluate the dry matter yield (DMY) of Brachiaria briz antha cv.MG5 and the weight gain of the animals under conditions of irrigated and non‐irrigated pastures.
