Resumen

SILVA, M.A et al. Forage yield and nutritive value in pennisetum clones harvested in the forest zone. Arch. zootec. [online]. 2011, vol.60, n.229, pp.63-74. ISSN 0004-0592.  http://dx.doi.org/10.4321/S0004-05922011000100008.

The objective of this work was to verify the MS production and nutritive value of five clones of Pennisetum. The samples were taken from an utile area of 2,0 m2 in each plot. After clipping the forage to standarize, four cuts were performed with 60-d intervals. In each plot, three tillers were oven-dried and grinded for laboratory analysis. The following response variables were determined: dry matter concentration (MS), crude protein (PB), neutral detergent fiber (FDN), acid detergent fiber (FDA), ether extract (EE), mineral matter (MM), in vitro dry matter digestibility (DIVMS), total carbohydrates (CHOT), and non-fibrous carbohydrates (CNF). The evaluated genotypes presented average MS yield of 1.7 and 2.1 t/ha/ cut, for leaf blade and stem, respectively. Average nutritive value was 21.1 and 15.1% for MS; 9.1 and 5.3% for PB; 73.2 and 77.7% for FDN; 40.3 and 47.4% for FDA; 9.6 and 11.6% for MM; 1.9 and 0.7% for EE; 56.2 and 56.3% for DIVMS; 79.3 and 82.4% for CHOT; and 11.4 and 9.7% for CNF, in leaf blades and stem, respectively. The clones presented medium to high heritability, similar biomass production and nutritive value, when harvested at 60 days of regrowth in the conditions of the forest zone of Pernambuco.
