Abstract
This study explored the effect of including plantain (Plantago lanceolata L.; PL) in perennial ryegrass (Lolium perenne L.; PRG)-white clover (Trifolium repens L.; WC) pasture on the milk composition and milk fatty acid (FA) and mineral concentrations of spring-calving dairy cows. The treatments were PRG-WC (GrC) and PRG-WC-PL (GCP) pastures. Milk samples were obtained from dairy cows (n = 13 per treatment) during early (61 ± 12 d in milking; EL) and late (214 ± 16 d in milking; LL) lactation. Cows grazing GCP produced milk with a lower fat concentration. Milk lactose concentration was greater from cows grazing GCP in LL. Cows grazing GCP produced milk with greater concentrations of polyunsaturated FA (g 100 g milk−1) and α-linolenic acid (g 100 g milk fat−1). Treatment did not affect milk mineral concentrations in EL. In LL, cows grazing GCP produced milk with lower concentrations of calcium (−10 %) and magnesium (−7 %) compared with GrC. Including PL in a PRG-WC pasture for dairy cows can beneficially alter milk FA composition.
