Abstract | The effect of partial substitution of soybean meal by equal quantities of flaxseed and lupins in diets of Holstein dairy cows and heifers was investigated. A total of 6 animals (30 multiparous and 30 primiparous) were allocated into two equal groups in a randomised block design and fed control (group CO) or modified (group FL) TMR diets from three weeks prior to calving until day 40 postpartum. The TMR of group CO contained corn, barley, soybean meal, rapeseed cake, corn silage, and Lucerne hay, whereas in group FL equal quantities of whole flaxseed and lupins were used to replace 50% of the soybean meal in the TMR. All animals were fed twice daily with a daily allowance of 24 kg dry matter intake per animal. Milking was carried out three times daily and milk yield was recorded during every milking. Milk samples were analysed for chemical composition and SCC content. White cheeses were manufactured from bulk milk of each group at industrial level. Bulk milk and white cheese were analysed for chemical composition and fatty acid profile; cheese was also assessed for its organoleptic properties. Results indicate that milk yield did not differ among groups. Lipid oxidation values were similar among the groups, for both milk and cheese. However, FL inclusion resulted in lower ( p < 0.05) protein carbonyls and higher ( p < 0.05) phenolic compounds in both milk and cheese samples. Milk from the FL group had decreased palmitic ( p < 0.05) and myristic ( p < 0.05) and increased oleic ( p < 0.05) and linolenic acid ( p < 0.05) when compared to group CO. White cheese from group FL showed a decrease in saturated fatty acids (SFA) ( p < 0.05), an increase in monounsaturated fatty acids (MUFA) ( p < 0.05), and a higher increase in polyunsaturated fatty acids (PUFA) ( p < 0.05) when compared with that of group CO. The white cheese of cows fed diets with flaxseed and lupins showed compositional and organoleptic properties quite similar to control group cheese; aroma, texture, and color were acceptable ... |
