Description
The objective of this study was to study the effect of different winter and summer forage systems on milk production and composition in beef cows. Charolais and Polled Hereford cows were assigned to receive either grass hay and supplemental feed or ryegrass pasture during the late winter/early spring period, and then allowed to either graze warmseason grass pasture on a continuous or rotational basis during the summer period. Representative cows were machine-milked on day 48 (hay/feed vs ryegrass), on days 117 and 175 (continuous vs rotational grazing) postpartum. Milk weights were recorded and converted to 24- hour yields. Samples were collected from each cow on each milk date for determination of butterfat, protein and lactose content in milk.
