Intake and Apparent Digestibility of Corn (Zea mays L.), Sorghum (Sorghum bicolor (L.) Moench) and Sunflower (Helianthus annuus L. ) Silages

[摘要] - The experiment was carried out with the objective of determining the daily average intake (DAI) and apparent digestibility coefficient (ADC) of corn, sorghum and sunflower silages nutrients. The nitrogen balance was also evaluated. Nine castrated, male sheeps, kept in metabolism cages, in a 3 x 3 (three treatments and three periods), latin square design, were used. DAI of dry matter (DM), acid detergent fiber (ADF) and crude protein (CP) of corn silage of sunflower silage did not differ. DAI of neutral detergent fiber (NDF) and ether extract (EE) were higher in corn and sunflower silages, respectively. ADC of DM and EE were higher in sunflower silage than in sorghum silage. ADC of NDF and CP were similar for all silages.
