Abstract

This work aimed to evaluate the effect of supplementation with concentrate containing or not soybean oil on rumen degradation of dry mater (DM), neutral detergent fiber (NDF) and acid detergent fiber (ADF) of Marandu grass managed with occupation period of two days with 28 days of rest and 2.6 AU/ha of stocking rate. An in situ trial was carried out with three dry crossbred ¾ Gyr x ¼ Holstein rumen cannulated cows arranged in 3 x 3 crossover design with three treatments: no supplementation (NS), supplementation with non-soybean oil concentrate (NO), supplementation with 7% soybean oil concentrate (SO). Incubation periods were 0, 6, 12, 36, 48 and 96 hours. There was no difference among treatments. The values of potential degradability of DM, NDF and ADF of marandu-grass determined in animals from NS, NO and SO were: 81.80%, 92.12% and 91.54%; 56.05%, 58.60% and 60.21%; 60.01%, 64.34% and 65.17%, respectively. Supplementation with concentrate containing or not 7% of soybean oil do not change rumen degradation parameters of marandu-grass.
