Chemical treatment of roughage Tratamento químico de volumosos

Abstract

Chemical treatment of roughage has been the aim of studies for a long time. However, until nowadays, many questions are arisen due to the efficiency of additives used in relation to the variation of answers, either in nutritive value of treated roughage or in performance of animals feed with diet containing such roughage. This revision will approach the main and most used products, which are anhydrous ammonia, urea, sodium hydroxide and calcium oxide. It has been noticed that ammonization (both for anhydrous ammonia and urea) has presented more efficient result in animal's performance when compared with sodium hydroxide or calcium oxide. However, regarding its nutritive value, both sodium hydroxide and calcium oxide have presented a higher efficiency in the decreasing of cell wall and in the increase of treated roughage' digestibility.O tratamento químico de volumosos tem sido objeto de estudos há muito tempo. Entretanto, até hoje muitas dúvidas são levantadas sobre a eficiência dos aditivos utilizados no que se refere à variação das respostas seja no valor nutritivo dos volumosos tratados, seja no desempenho dos animais alimentados com dietas contendo estes volumosos. Esta revisão abordará os principais e mais utilizados produtos químicos, que são a amônia anidra, a uréia, o hidróxido de sódio e o óxido de cálcio. Tem-se verificado que a amonização (tanto com amônia anidra quanto uréia) tem apresentado resultados mais eficientes no desempenho animal quando comparada ao hidróxido de sódio ou óxido de cálcio. Entretanto, em relação ao valor nutritivo, tanto o hidróxido de sódio quanto o óxido de cálcio têm apresentado maior eficiência na redução da parede celular e no aumento da digestibilidade de volumosos tratados.
