Ruminal degradation of the biomass of grass hays genre Cynodon spp.

Abstract

Objetivou-se avaliar a degradabilidade in situ de diferentes dietas a base de fenos de genótipos (Tifton 68, Tifton 85, Jiggs, Russel, Vaquero e Coast cross) pertencente ao gênero Cynodon, em seis ovinos da raça Santa Inês, com peso médio de 40 kg, providos de cânulas ruminais, mantidos em baias individuais. As dietas foram incubadas em ordem decrescente de 96, 72, 48, 24, 12, 6, 3 e 0-h. Utilizou-se o delineamento experimental em quadrado latino, com seis tratamentos, seis animais e seis repetições. As dietas, a base de feno de Jiggs, Tifton 68, Coast Cross e Tifton 85, apresentaram degradabilidade potencial acima de 59%. Entretanto, as dietas, a base de feno de Jiggs e Coast cross, apresentaram menores médias (p<0,05) (30,28 e 28,90%) para degradabilidade efetiva, respectivamente em relação as demais dietas. A utilização de feno de gramíneas pertencente ao gênero Cynodon apresenta potencial para utilização em dietas para cordeiros uma vez considerados os parâmetros observados nesta pesquisa.

Aimed to evaluate the in situ degradability of different diets based on hay genotypes (Tifton 68, Tifton 85, Jiggs, Russel, Vaquero and Coast cross) belonging to the genus Cynodon, in six Santa Inês sheep, with an average weight of 40 kg, and fitted with rumen cannulas, were kept in individual pens. The diets were incubated in decreasing order of 96, 72, 48, 24, 12, 6, 3 and 0-h. We used the Latin square experimental design with six treatments, six animals and six replications. The diets, based on hay Jiggs, Tifton 68, Tifton 85 and Coast Cross, degradability showed above 59 %. However, diets based on hay Jiggs and Coast cross had lower mean (p<0.05) (30.28 and 28.90%) for effective degradation, respectively, on the other diets. The use of grass hay belonging to the genus Cynodon has potential for use in diets for lambs once considered the parameters observed in this study.
