The composition of cattle diets is one the most important parameters influencing meat quality .Effects of pasture alone and supplementation with dehaydrated Medicago sativa on carcass and meat quality were studied in Marchigiana beef cattle, in particular lipid and stability.
Meat quality measurements were made on Longissimus dorsi (LD) muscle in 20 animals slaughtered at 660-700 kg.
The amount of lipids in the control group was lower with higher percentage of polyunsaturated fatty acids (PUFA), especially linoleic (C18:2) and linolenic (C18:3) acid. There were significant differences (P≤0.01) of TBARS values that were higher in the group fed with supplementation of Medicago sativa than in the other group, the control one.
Today people try more and more to replace soybean with other GMO-free protein foods. This study documents how the use of dehydrated Alfalfa meal in calf nutrition instead of soybean enriches the meat in polyunsaturated acids but, at the same time, promotes the processes of lipid oxidation.
