The research was carried out at UNESP - Jaboticabal to evaluate the dry matter yield (YMP), chemical composition of the cool season forage species: oat (Avena strigosa Schreb) and triticale (X Triticosecale Wittmack) no-till seeding in annual summer species cultivated area with pearl millet (Pennisetum americanum (L.) K. Schum.) or sorghum-sudangrass hybrid (Sorghum bicolor (L.) Moench x Sorghum sudanense (Piper) Stapf). The forage was grazed by Holstein cows in rotational stocking system. It was used the completely randomized outline in split plot scheme with four replications. In the first experiment the following treatments were evaluated: AS - oat no-till seeding in sorghum-sudangrass hybrid stubble, AM - oat no-till seeding in pearl millet stubble, TS - triticale no-till seeding in sorghum-sudangrass hybrid stubble, and TM - Triticale no-till seeding in pearl millet stubble. The forages presented similar dry matter evaluation, however the YMP decreased on the second evaluation. It was observed highest crude protein, ADF on the first yield and hemicellulose on the second evaluation. The harvest time did not affect the forage NDF content. Triticale showed lower CP and higher cell wall content compared to the oat forage.
