Abstract

Our study evaluated the effect of grass silage digestibility and concentrate intake on milk yield of dairy cows. Eighty group mean treatments comprising different grass silage digestibility and concentrate levels were collected from nine published studies. Linear mixed models were developed with study as random
effect. Silage quality was included in the models as organic matter digestibility (OMDs) or energy concentration. Concentrate intake (DMIc), concentrate proportion of total dry matter intake or energy intake were further tested. Best fit model included curvilinear effect of DMIc and linear effect of OMDs.
Moreover, there was an interaction between DMIc and OMDs, where higher digestible silages resulted in higher milk yield, but marginal response in milk to increase of DMIc was lower. For low digestible silages, highest milk production was achieved with higher DMIc as compared to high digestible silages.
