Abstract

The influence of replacing silage with sorghum silage in the diet of dairy buffalo cows on metabolic status and on milk yield, chemical characteristics, and fatty acid profile was studied. Forty dairy buffalo cows were included in the trial and divided into two homogeneous groups (SS, sorghum silage and CS, corn silage). Blood was collected at the end of the trial (120 days), individual milk yield was registered daily. Samples of milk were monthly collected and analyzed for fat, protein, and lactose. Moreover, fatty acid profiles of silages and milk were determined. Buffalo cows fed sorghum silage showed an average milk yield higher than group CS (kg/d 10.120 vs. 9.270; p < 0.05), probably due to the lower lignin content of sorghum silage (31.0 g/kg dry matter (DM)) compared to corn silage (47.0 g/kg DM) and, by consequence, to the higher digestibility of SS diet. The percentage of linoleic acid was significantly higher in milk of group CS (C18:2: 1.27 vs. 2.05%; p < 0.01) due to the higher content of these acids in corn than in sorghum silage. The omega 6/omega 3 ratio was significantly lower in milk from buffalo cows fed sorghum than those fed corn silage (7.8 vs. 12.9; p < 0.01). Serum biochemistry showed no negative effects of the corn replacing with sorghum.
