Avaliação de fontes de amônia para conservação do feno de alfafa (Medicago sativa L.) armazenado com alta umidade

Abstract: RESUMO -O estudo foi desenvolvido com o objetivo de avaliar duas fontes de amônia (amônia anidra-NH 3 ou uréia) para conservação do feno de alfafa (Medicago sativa L.) armazenado com alta umidade. Foram estudados os seguintes tratamentos: A -feno com 12 a 15% de umidade e não-tratado; B -feno com 24 a 27% de umidade e tratado com 1,0% de NH 3 na MS; C -feno com 24 a 27% de umidade e tratado com 0,9% de uréia na MS; D -feno com 24 a 27% de umidade e tratado com 1,8% de uréia na MS; E -feno com 34 a 37% de umida… Show more

“…These fungi are found in improperly stored forage. The fungi Cladosporium, Curvularia, Aspergillus and Penicillium occur in grass hay (Cynodon dactylon (L.) Pers) baled with different moisture contents (Freitas et al, 2002). However, according to these authors, a decrease after 30 days of storage occurred in the incidence of Curvularia (a field fungus), and an increase occurred in the incidence of Aspergillus and Penicillium, fungi typically found in storage.…”

“…Segundo Freitas et al (2002), a amônia (NH 3 ) formada a partir da ureia na presença de uréase possui ação antimicrobiana e inibindo o desenvolvimento de leveduras e fungos, justificando as reduções nas populações desses microrganismos apresentadas neste estudo.…”
