dc.descriptionGrains represent important sources of energy to horses. Feeding diets with high-grain contents is associated withsome feeding disorders and less feed utilization [1] due tomicrobial profile disturbance [2] and impaired fibrolytic activity in the hindgut [3]. Therefore, partial replacement of grains (energy sources) with other feeds, rich in fibers, would appear to be a good alternative solution to prevent such problems and increase feed utilization and reduce feeding costs.-
dc.descriptionThe aim of the study was to evaluate the fecal fermentation of partial replacing steam rolled corn with soybean hulls (SH) or prickly pear cactus (PC) as energy source in horse diets, in the presence of Saccharomyces cerevisiae. Steam rolled corn was replaced with SH at 0% (control), 7.5% (SH75), and 15% (SH150) in the first trial, whereas it was replaced with PC at 0% (control; the same of the first trial), 7.5% (PC75), and 15% (PC150) in the second trial. Yeast of S. cerevisiae was added at 0, 2, and 4 mg/g dry matter (DM) of incubated substrates. Fecal inoculum was obtained from four adult English Thoroughbred horses fed on an amount of commercial concentrate and oat hay ad libitum. Interactions observed between PC rations and yeast doses for the asymptotic gas production (GP), the rate of GP and carbon dioxide (CO2) production during some incubation hours. Moreover, with no effect due to SH rations (P > .05), increased (P < .05) rate of GP was observed with the ration PC75 compared with other rations. Besides, PC75 and PC150 rations with 0 mg yeast/g DM linearly decreased (P < .05) CO2 production at some incubation hours. However, SH75 and SH150 ration had increased (P ¼ .005) DM degradability (DMD). Yeast addition at 2 mg/g DM increased the asymptotic GP (P ¼ .048) with the SH75 and PC150 rations. The level of 4 mg yeast/g DM increased the asymptotic GP (P ¼.048) from the SH150 ration. Yeast addition at 2 and 4 mg/g DM increased (P < .05) the asymptotic GP from PC75 and PC150 rations, respectively, with increasing DMD with the both doses. Yeast addition increased (P <.05) CO2 production from SH75, SH150, PC75, and PC150 rations. It could be concluded that SH and PC can replace steam rolled corn at levels of 7.5% to 15% without negative effect of fermentation kinetics and with better fermentation performance in the presence of yeast at 2 mg/g DM of substrates.-
