Nutritional value and digestible dry matter production of oat genotypes for ensiling

Authors

Abstract

This study evaluated dry matter yield and nutritional characteristics of different oat genotypes (Avena spp.) for ensiling. Treatments consisted of genotypes of white oat IPR 126 (Avena sativa), black oat Cabocla IPR and Agrocoxilha (Avena strigosa), and BRS Madrugada and BRS Centauro (Avena vertis). Oats were harvested at the phenological stage of milk/dough grain. The design was a completely randomized block scheme, with five treatments and three replications per treatment. The IPR Cabocla genotype showed the highest dry matter content (before and after silo opening) and in vitro dry matter digestibility of fresh forage. No differences were observed for in vitro dry matter digestibility and dry matter losses among silages. The highest silage digestible dry matter yield (kg ha-1) was observed for the BRS Centauro genotype. Thus, despite the better nutritional quality presented by the IPR Cabocla genotype before ensiling, BRS Centauro genotype presented a higher yield of digestible dry matter per hectare.
