Abstract

Objetive: To determine the effect on weight gain, rumen bioactivity and rumen pH in weaned sheep using fresh rumen fluid (FRF) from cattle. Materials and methods: Nine weaned sheep with (aproximated same age and weight), were randomized into three groups: Treatment 1), 400 ml of FRF, Treatment 2), 200 ml of FRF and Treatment 3), and 4) Control without FRF. The FRF was administered through oral route, using a single dose as baseline. Parameters studied, were taking at day 0 and then every 15 days during a 60 days period. For statistical analysis ANOVA and the Tukey'stest for each mean comparison were performed. Results: There were not significant differences (p>0.05) for daily weight gain, average profits between treated groups and control group (194.4 g/d, 169.4 g/d and 157.8 g/d respectively). Rumen bioactivity does showed changes after the administration of 400 ml of FRF (p<0.05). The pH showed only significant changes after 15 days of the administration of 400 ml of FRF. Conclusions: The administration of FRF did not cause significant increases on daily weight profit; nevertheless, it showed favorable effects on rumen bioactivity in weaned sheep.
