Avaliação de qualidade e bromatologia de silagens e perícia do manejo na ordenha no município de Barão de Cotegipe

Abstract

Dairy cattle breeding in the Alto Uruguai region of Gaúcho has great social and economic importance where most of the properties that make up this region are part of the dairy. The main source of feed for the herd of the region in question is the silage, mainly of maize (Zea mays), forage that is considered in the nutritional parameters the most indicated for this practice. The present study had as objective to do the bromatological analysis of 10 producers in the municipality of Barão de Cotegipe, in the state of Rio Grande do Sul, where were collected uniform samples of the silos of the properties visited and applied 2 questionnaires, where they were covered in the first questionnaire all the parameters involving from planting to cutting the forage, and in the second, all pre and post milking management of dairy cows. It was observed that the dry mass content was higher when both the planting and the cut were delayed comparing with the other producers, the line spacing of 0.45 and 0.5 were the ones that stood out most involving Protein crude and Ethereal Stratum. For milking purposes, the use of cloths to dry the ceilings is completely inefficient, increasing the values of CCS and CBT reducing the value added to the milk.
