Abstract

The research was conducted aiming to evaluate some characteristics of silage from two maize varieties. The following treatments were designed: T1 –- maize silage, variety “Cati verde”, plants with ears; T2 –- maize silage, variety “Cati verde”, plants without ears; T3 –- maize silage, variety “Cati verde”, plants without ears + 5% of citrus pulp; T4 –- maize silage, variety “AL Bandeirante”, plants with ears; T5 -– maize silage, variety “AL Bandeirante”, plants without ears; T6 –- maize silage, variety “AL Bandeirante”, plants without ears + 5% of citric pulp. Harvesting and silage were conducted when maize were in a “green stage” and for treatments without ears were discharged and only plants were processed into silage. Plastic buckets of 15 kg capacity were used as experiment silos. The experiment was evaluated in a completely randomized design with five replications. Contents of dry material resulted under the recommended to assure an adequate fermentation and contents of crude protein, in an average value of 7.7%, were not affected by the presence or absence of ears. Citrus pulp did not increase the silages dry matter content. Fiber contents were high, in an average value of 65% (DNF) and 47% (DAF). The average value to "in vitro" digestibility of dry material was estimated in 60%. The two varieties of maize resulted in silage with similar characteristics. In order to obtain higher contents of dry material, maize plants should be kept in the field for some time after harvesting.
