Caracterização nutricional de tortas oleaginosas e avaliação de diferentes inóculos para digestibilidade in vitro de alimentos

Abstract

The objective of this work was to determine the characterization bromatological, the in situ degradability and in vitro digestibility using four levels of bovine fecal , equine and rabbit ( 200/200, 300/100, 400/100, 500/100 g / ml ) for crushed oil derived from cold mechanical pressing to remove kernel oil , canola (Brassica napus) , safflower (Carthamus tinctorius L.) , radish (Raphanus L. var.oleiferus Metzg stivus.) and soybean (Glycine max) values for their crushed were 40.71 %, 24.18 %, 38.40% and 44.28% protein; these foods shown to be highly degradable food for tart radish and soybean cake had values of crude fiber of 17.78% and 7.79% respectively. The kinetic parameters of dry matter and protein crushed evaluated by the in situ technique was performed in three fistulated cattle, and incubated in the food bags TNT decreasing in time of 72, 48, 36, 24, 18, 12,6, 3 hours, crushed soy and radish were the ones that stood out with high ruminal degradability of DM and CP ( 92.67, 83.03 and 87.49, 79.03%) showed the soybean cake fraction "a" soluble 43.10 and 27.63% for DM and CP pie with lower degradability was pie safflower. Finally evaluated their in vitro dry matter digestibility (IVDMD) using the standard technique with four 4 types of inoculum originating from rumen fluid from cattle feces faeces faeces equine and rabbit in four dilutions of 1:1, 1:3, 1:4 and 1:5. inoculum at dilutions of 1:3 showed better percentage IVDMD. It can be concluded that the sources of oil have nutritional potential compared to soybean cake and the use of feces as a source of inoculum for in vitro showed potential to be used as alternative inoculum for in vitro digestibility of DM, however more research is needed.
