Differences in efficiency for milk production between four dairy breeds



Differences in efficiency for milk production between four dairy breeds



35th Annual Meeting of the EAAP, The Hague, Netherlands, 6-9 August 1984 Vol 1 Summaries Study Commissions Genetics, nutrition, management (Paper GN4.6): 2



In the 1st of 2 experiments, Holstein-Friesian, Dutch Red and White and Dutch Friesian cows in the 1st lactation were compared for efficiency of milk yield on an ad lib. diet of (1) grass + maize silage or (2) grass, maize silage and 50% concentrates (on a dry matter basis). Efficiency was measured as the ratio between milk energy output and feed energy input. In the 2nd experiment, the above 3 breeds plus the Jersey were compared.
