Inclusão de óleos funcionais da mamona e do caju na dietas de ovinos

Abstract

The work aimed to evaluate the effect of inclusion of functional oils extracted from the castor bean (Ricinus communis L.) and the cashew bark (Anacardium occidentale L.) on the nutrient digestibility in sheep diet. The animals were fed with concentrated soy-meal basis, wheat bran, corn bran, and the massive consisting of Tifton hay in a 50:50 ratio of forage and concentrate. Levels were added 2g, 4g and 6g / day was functional oils and a control group without the inclusion of oils. The experiment was conducted at the Universidade Tecnológica Federal do Paraná - UTFPR, campus Dois Vizinhos - PR, in UNEPE animal metabolism. 4 sheep were used mongrel, with an average weight of 50kg, rumen cannula carriers, confined in digestibility cages with individual drinkers and feeders were assigned to a 4x4 Latin square design. Each experimental period had the duration of 20 days with 15 days to adapt the animals to the diet and 5 days to carry out the collection of faeces and food scraps. Samples collected from the diet, the remains and feces were weighed and pre-dried in a forced air oven 55 will for 72 hours after consumption analyzes were performed and digestibility of DM, OM, NDF and CP. The inclusion of these plant extracts had no significant effect (p> 0.05) for consumption, so little to digestibility. Therefore, we conclude with this research that these functional oils have little or no influence on the intake and digestibility of nutrients.
