“…The in vitro dry matter digestibility levels were similar in the cuts performed on 09/07/14 with a 64day interval and in the cut performed on 02/19/14 with an interval of 35 days, and higher than the cut done on 10/08/14 with an interval of 93 days. In evaluating the IVDMD levels of Coastcross, Tifton 68 and Tifton 85, Cedeno, Rocha, Pinto, Muniz and Gomide (2003) found IVDMD values of 60.69%, 65.77% and 60.53%, respectively, at the 42-day cut interval, and values of 47%, 30%, 55.49%, 57.41% at 70 days of cut interval, respectively, for the same forages, demonstrating that the evaluated populations showed good quality with digestibility levels above 55% (Leng, 1990). The lower IVDMD content at the 93-day cut interval is due to changes in the chemical composition of forages with advancing physiological age of the plants (Carvalho & Pires, 2008).…”
