Gulati, A., Galvin, N., Kennedy, E., Lewis, E., McManus, J., Fenelon, M. and Guinee, T. Effect of reducing daily herbage allowance during early lactation on composition and processing characteristics of milk from spring-calved herds. International Dairy Journal, 2019, 92, 69-76. doi: https://dx.doi.org/10.1016/j.idairyj.2019.01.008Abstract
The study investigated the effects of reducing daily herbage allowance (DHA) from 15.0 to 11.8 kg dry matter per cow (>3.5 cm post grazing sward height) to a spring-calved herd during early lactation on the composition, rennet coagulability and heat stability characteristics of milk during early lactation (EL, 29–70 days in milk, DIM), mid lactation (ML, 78–183 DIM), and late lactation (LL, 205–267 DIM). Samples of milk were taken at approximate 10 d intervals during EL and at 1–3 week intervals during ML and LL. Reducing DHA led to reductions in milk yield, milk solids yield, and concentrations of protein (∼0.22%, w/w) and casein (0.13%, w/w) during EL. Otherwise, it had little effect on milk composition or on the selected processing characteristics in ML, LL or overall lactation. Stage of lactation resulted in comparatively large changes in most compositional parameters, rennet gelation and heat stability.Funder
