Resumo: The aim was to evaluate the addition of sunflower meal hydrolyzed with calcium hydroxide (Ca(OH)2) in cattle diets and it influences on ruminal parameters of pH and ammonia nitrogen. This study also evaluate the ruminal degradability of dry matter, crude protein, neutral detergent fiber and acid detergent fiber from sunflower meal with or without treatment with 15, 30, 45, and 60 g of Ca(OH)2 kg-1 The sunflower meal hydrolysis did not influence the ruminal values of pH and ammonia nitrogen. The soluble fractions of dry matter and crude protein decrease with sunflower hydrolysis. Therefore, the potential degradation of crude protein did not affect, indicating that a posterior intestinal utilization of this protein would not be affected. The neutral detergent fiber solubility increase with hydrolysis, with lower percentages of undegradable fraction with 15 and 60 g of Ca(OH)2 kg-1  . The hydrolysis increases the potential degradable fraction and the degradability of neutral detergent fiber of sunflower meal without prejudicing it protein use in rumen. The use of 15 g of Ca(OH)2 kg-1 would be satisfactory to improve the degradation of neutral detergent fiber of sunflower meal.

A hidrólise do farelo de girassol não influenciou os valores ruminais de pH e nitrogênio amoniacal. A fração solúvel da matéria seca e proteína bruta diminuíram com a hidrólise. No entanto, não houve diferenças na degradação potencial da proteína bruta, indicando que um posterior aproveitamento intestinal desta proteína não seria prejudicado. A solubilidade da fibra em detergente neutro aumentou com a hidrólise, e menores porcentagens de fração indegradável foram obtidas com 15 e 60 g de Ca(OH)2 kg-1 A hidrólise possibilitou o aumento da fração potencialmente degradável e as degradabilidades da fibra em detergente neutro sem prejudicar seu aproveitamento proteico no ambiente ruminal. A utilização de 15 g de Ca(OH)2 kg-1 seria suficiente para melhorar a degradação da fibra em detergente neutro desse ingrediente.Departamento de Diagnóstico e Pesquisa Agropecuária.
