Resíduo agroindustrial da carnaúba como fonte de volumoso para a terminação de ovinos

Abstract: Resumo -O objetivo deste trabalho foi avaliar os efeitos da amonização com diferentes níveis de ureia e do uso de grãos de soja como fonte de urease, na melhoria da composição químico-bromatológica do resíduo agroindustrial da carnaúba (Copernicia prunifera), conhecido como bagana (BC). Os níveis de ureia utilizados foram 0, 2,5, 5, 7,5 e 10%, em relação à percentagem de matéria seca total da BC; e os níveis de grãos de soja tostados foram de 0 e 20%. Foram também avaliados o consumo de ração e o desempenho de… Show more

“…Ammoniation with 3% urea reduced (P<0.0002) the ADF content compared to the untreated hay, irrespective of the level of N in the fertiliser, an effect caused by the breakdown of ester bonds between molecules of structural carbohydrates, also seen by Schmidt et al (2003) and Gobbi et al (2005) in hay from signal grass (Brachiaria decumbens) and Zanine et al (2006) , when the HCEL content of the ammoniated hay exceeded that obtained for the non-ammoniated, due to the proportionally lower ADF content (Table 3) in relation to the NDF (Table 2). Gomes et al (2009) observed an increase in the NDF content of carnauba straw (Copernicia prunifera) with the DM ammoniated with up to 10% urea, and Schmidt et al (2003) obtained an increase in HCEL content for hay from signal grass ammoniated with 5% urea, compared to the untreated hay.…”

“…According to Gomes et al (2009), the odour of ammonia can affect intake by animals. Martins et al (2014) evaluated the effect of adding 1% urea during the ensiling of sugarcane for diets for Holstein 9 Gyr crossbred cows and also found a decrease in the animals' intake.…”

“…O termo "carnaúba" é derivado da língua indígena tupi e significa "árvore-que-arranha". A espécie é conhecida ainda como "árvore da vida", pois oferece uma infinidade de usos econômicos (GOMES et al, 2009). Sua principal riqueza está na cera que recobre as folhas, principalmente as mais jovens, tornando-a internacionalmente conhecida como "carnauba wax".…”
