REVUELTA LLANO, Danilo. Changes in aminic nitrogen of silages. Rev Cie Téc Agr [online]. 2012, vol.21, n.3, pp.90-92. ISSN 2071-0054.

This paper investigated quantitative changes of aminic nitrogen as a important protein breakdown parameter in laboratory scale silages.The experiments were performed from November to April (rainy season) of 2010 year at the Agronomy Faculty of Chianga (13km from Huambo City) in Angola. It showed that increasing aminic nitrogen below threefold value is a reasonable guide for optimal protein preservation in silages. The potenciometric formol method for aminic nitrogen determination is simple, rapid and economic. It is recommended this chemical analysis for routine control of silage quality.

Palavras-chave : aminic nitrogen; protein degradation; laboratory silage; postharvest.
