Avaliação nutricional e cinética de degradação in vitro de concentrados proteicos utilizados na alimentação de ruminantes

Abstract: ResumoAvaliaram-se concentrados proteicos através da composição bromatológica, fracionamento de carboidratos e proteínas e cinética da degradação in vitro em líquido ruminal de bovinos e ovinos. Foram utilizados farelos de soja (FS) e de algodão com casca (FA), grão seco destilado de milho (DDG), tortas de girassol (TG) e de crambe (TC). Determinou-se a composição bromatológica e os fracionamentos de carboidratos (A+B1, B2 e C) e de proteínas (A, B1+B2, B3 e C). O ensaio de degradabilidade in vitro foi realiza… Show more

“…2009) avaliando diferentes alimentos concentrados obtiveram uma taxa de degradação total da MS de 5,74 e 5,71% para farelo de soja e milho, respectivamente. Valores inferiores foram obtidos por Pegoraro et al, (2017) para farelo de soja (2,64%), farelo de algodão (2,37%), torta de girassol (2,65%) e DDG do milho (3,51%) e Teixeira (2014) que obtiveram taxas de 2,67% para DDG do milho e 6,65% para farelo de soja.…”

“…Ruminal fluid collection was performed over a 24 hour period, with an interval of 2h00 in between each one, starting at 8:30 in the morning, before food was supplied, and ending at 6:30 on the following day. Approximately 80 mL of ruminal fluid was collected from the intermediate area of the rumen for pH reading, with this procedure being performed immediately after collection, using a bench pH meter (Pegoraro et al, 2017).…”

“…In the production of biodiesel, some by-products are generated, which, although considered pollutants, are available and presenting a residual oil content higher than that contained in the crambe meal (Canova, 2015). The crambe cake contains 870-940 g/kg dry matter, 240-340 g/kg crude protein, 180-290 g/kg ether extract, 300-550 g/kg neutral detergent fibre (NDF), and 190-244 g/kg acid detergent fibre (ADF) (Brás et al, 2014;Canova et al, 2015;Silva et al, 2015;Goes et al, 2016;Pegoraro et al, 2017;Goes et al, 2018). The crambe cake contains 50.0-77.4 mmol/kg DM of glucosinolates and 56% erucic acid of total fatty acids (Böhme et al, 2005).…”
