Qualidade da silagem de cana-de-açúcar associada a diferentes fontes de carboidratos

Abstract

This study aimed to evaluate the effect of using microbial inoculant associated with different percentages of wheat bran and soybean hulls in sugar cane silage on the physical, qualitative and bromatológicos aspects. The experiment was conducted at the Campus UTFPR Two Neighbors PR, using a variety of sugar cane RB925345 chosen. The treatments consisted of C - cane without inoculation; CA - cane + biological inoculant (Lactobacillus buchneri); CCS10 - inoculant + cane + 10% DM of soybean hulls; CCS20 - inoculant + cane + 20% DM of soybean hulls; CFT10 - inoculant + cane + 10% DM of wheat bran; CFT20 - inoculant + cane + 20% DM of wheat bran; CFC10 - cane inoculant + + 5% DM of wheat bran and 5% DM of soybean hulls; CFC20 - inoculant + cane + 10% DM of wheat bran and 10% DM of soybean hulls; each treatment consists of four repetitions of minissilos. Harvest was done manually and then the cane was chopped in a stationary chipping hammer, with an average particle size of 2 cm. The chopped material was ensiled in minissilos containing 3.5 kg of the material before ensiling was sprayed biological inoculant Lactobacillus buchneri, and quantities of wheat bran and soybean hulls were added to homogenization of all material fodder being made. After compacting the minissilos were sealed and they were closed for approximately 60 days. Assessment of losses effluents and Forage dry matter contained in the beginning and the end of ensilamento was performed. The additives soybean hulls and bran used in forage sugarcane proved to be efficient in controlling the quantitative losses during fermentation, they acting individually or together as a great alternative to increase the content of DM and CP, reduce effluent losses. Noting that the treatments containing 20% CS or TF were the most significant. The inoculant improved silage fermentation pattern of sugarcane, and the cost factor is the choice.
