Abstract

This study aimed to investigate the prevention of acidosis in ruminants, which causes yield and financial losses, and toevaluate the effects of feed additives on starch digestion. Four male Bafra yearling lambs with cannulated rumens were used in a 60-daystudy. Each lamb underwent 10 days of adaptation to a ration and 5 days of sampling for four different rations including a control ration(CR), monensin ration (MR), Saccharomyces cerevisiae ration (SR), and a ration with the combination of monensin and Saccharomycescerevisiae (MSR). The experiment followed a 4 × 4 Latin-square design. Dry matter intake and digestion rates were recorded as 2404 g(85.49%), 2270 g (88.41%), 2321 g (90.93%), and 2227 g (88.74%) for the CR, MR, SR, and MSR diets, respectively. Starch consumptionand digestion rates were respectively 477.62 g (81.75%), 791.82 g (93.11%), 809.53 g (94.01%), and 776.71 g (92.16%). Rumen pHvalues at baseline were 6.78, 6.56, 6.94, and 6.67 and at 6 h were 6.49, 6.42, 6.44, and 6.59 for CR, MR, SR, and MSR, respectively. Insitu degradation was significant at 4, 8, 12, and 48 h, with the SR and MSR diets showing the highest degradation percentages at mosttimepoints. The highest in situ degradation was seen at 48 h for MR (98.42%) and SR (96.98%). The results demonstrated that monensinand Saccharomyces cerevisiae supplementation in high-starch rations improved feed efficiency, helped prevent acidosis, and mitigatedthe negative effects of high-concentrate diets on the rumen.
