Composicao quimica e consumo voluntario do feno e da silagem da parte aerea da mandioca (Manihot esculenta Crantz) - 8(2):203-213

Se evaluo el consumo voluntario y la composicion quimica de heno y ensilaje preparados con la parte aerea de yuca cv. IAC 12- 829, de 1 ano de edad, en la Escola Superior de Agricultura de Lavras (Minas Gerais, Brasil) durante 1982-83. Se estudiaron 4 tratamientos: T1, heno de la parte aerea total; T2, ensilaje de la parte aerea total; T3, heno del tercio superior de la parte aerea total; y T4, ensilaje del tercio superior de la parte aerea. Se determino la composicion quimica de muestras multiples ofrecidas a ovejas, usando los siguientes parametros: MS, PC, fibra cruda, hidratos de carbono solubles, Ca, P, EB y pH. Se mantuvieron 20 carneros castrados en jaulas metabolicas individuales durante 21 dias con el objeto de estimar el consumo voluntario, utilizando para este fin un diseno de bloques al azar con 5 repeticiones y 4 tratamientos. Se determinaron el consumo voluntario de MS, la MS digestible, la proteina digestible y la energia digestible. Se obtuvo una mejor calidad, con el ensilaje y con el heno, cuando se uso el tercio superior de la parte aerea. El consumo voluntario de proteina fue mayor cuando se utilizo ensilaje. (RA-CIAT) The voluntary intake and chemical composition of hay and silage made of the aerial part of 1-yr-old cassava cv. IAC 12- 829 were evaluated at the Escola Superior de Agricultura de Lavras (Minas Gerais, Brazil) during 1982-83. Four treatments were studied, namely, T1, hay of the whole aerial part; T2, silage of the whole aerial part; T3, hay of the upper third of the whole aerial part; and T4, silage of the upper third of the aerial part. The chemical composition of multiple samples offered to sheep was determined using the following parameters: DM, CP, crude fiber, soluble carbohydrates, Ca, P, GE, and pH. Twenty wethers were kept for 21 days in individual metabolic cages in order to estimate voluntary intake using a randomized block design with 5 replications and 4 treatments. DM voluntary intake, digestible DM, digestible protein, and digestible energy were determined. Better quality was achieved, both with silage or hay, by using the upper third of the aerial part. Voluntary intake of protein was higher with silage. (AS)
