| Description | The aim of the study was to evaluate the effect of inclusion of sorghum silage into dairy cow diets on the eighteen-carbon fatty acids (FA) in milk fat. The on-farm experiment was carried out on mid-lactating Czech Fleckvieh cows and was divided into two periods. In the first period cows were fed a total mixed ration (TMR) based on maize silage and grass haylage (Control) while in the second period grass haylage was partially replaced by sorghum silage (Sorghum). The FA profiles were analysed using gas chromatography with flame ionization detection. The total content of C18 acids was on average 34.6% of all FAs in Sorghum and 29.4% in Control. A higher content of stearic, oleic, linoleic and ?-linolenic acid was found in Sorghum compared to Control. The inclusion of sorghum silage into the ration had a positive effect on the content of polyunsaturated FAs and n-3 FAs. |
