Abstract

The experiment was carried out to study the nutritional value of six corn hybrids for silage production. The hybrids studied were: C901, C915, C125, C855, C808 and C805. Three crossbred heifers with ruminal cannulas received ad libitum a diet composed by corn residue silage, soybean meal and minerals. The parameters evaluated were in situ degradability of dry matter (DegDM), neutral detergent fiber (DegFDN) and in situ digestibility of dry matter (ISDMD). After thirteen days of adaptation period to the ration, 3.5 g of corn samples were placed in nylon bags and incubated for 6, 12, 24, 48 and 96 hours in the rumen. Averages were compared with the Tukey test (p < 0.10). The results for DegDM (potential and effective), DegFDN (potential and effective) and JSDMD were: C901 - 81.1 ab.; 83.0 a.; 50.0 a.; 62.0 a.; 24.2; C9l5 - 81.5 a.; 83.2 a.; 52.0 a.; 54.2 bc.; 21.8; C125 - 72.8 c.; 74.9 c.; 43.7 bc.; 56.2 abc.; 21.4; C855 - 78.0 abc.; 78.4 b.; 43.2 c; 59.7 ab.; 23.5; C808 - 76.9 abc.; 78.0 b.; 49.0 ab.; 50.9 c.; 20.9; C805 - 76.0 bc.; 77.3 bc; 46.5 abc.; 57.0 abc; 23.1. It was possible to conclude that C915 and C901 show the highest potential for production of good nutritional value silages.
