Valor nutritivo do pé de milho seco (Zea mays) determinado num ensaio de digistibilidade com bovinos em gaiolas

Abstract

Three crossbred Jersey steers were used in a digestion trial (in cages), to determine the nutritive value of ground corn fodder (Zea mays). Collection period lasted for seven days (after five days of adaptation to the feed and three days to the cages). Chemical composition of ground corn fodder was as follows: Dry matter (DM) 83.30%; Crude protein (CP) 7.38%; Ether extract (EE) 2.82%; Crude fiber (CF) 19.62%; Nitrogen free extract (NFE) 65.67%. Data for coefficients of digestibility were as follows: DM 57.20%; CP 27.55%)EE 64.57%; CF 42.38%; NFE 66.32%, being the Total Digestible Nutrients equal to 57.99%
