Utilização de sal proteinado na cria e recria de bovinos de corte

Abstract

The beef cattle industry in Brazil is set out in six major ecosystems: tropical humid (northern region), semi-arid region (northeastern region), savannas and wetlands (the Midwest), atlantic (Southeast) and subtropical (southern ), which present a wide variability of climate, soil and vegetation. The country is a major exporter of meat, with its largest herd concentrated in central-western China, the world trend of intensification of production of beef cattle, with emphasis on reducing breeding age heifers, has an effect on the Rio Grande South A critical period of food deficiency to the fold corresponds to autumn, whereas rangelands have already completed their growth and crop species cool-season annual still do not provide conditions for grazing, corresponding with the period of post - weaning animals. The native pasture is a low cost alternative, but offers low nutrient levels less than 7% CP in DM. An alternative to address these deficiencies is the use of protein salt. The purpose of the protein and mineral supplement is to provide degradable nitrogen to meet the minimum requirement of 7% crude protein in the rumen. The recovery of body condition of cows can be made before or after birth, with disagreements over the best time. The complexity of the phase of establishing the concept that additional broiler breeder flocks in Brazil is economically unfeasible, possibly explaining the low number of national studies involving supplementation of brood cows.
