Long term farm study of organic milk production — moderate concentrate inputs and high milk yields on Tingvoll farm

Long term studies of organic milk production on a Norwegian organic farm (Tingvoll farm) show that it is possible to achieve high milk yields with moderate concentrate inputs in organic milk production with Norwegian Red Cattle. The milk yields at Tingvoll farm were generally higher, and the concentrate input lower than the average of all Norwegian dairy farms. Average annual milk yields, as well as annual concentrate consumption per cow increased during the study period both for organic and conventional dairy production in Norway. The results from Tingvoll farm may inspire conventional dairy farmers to convert, since the differences to organic production are not necessarily too large. Alternatively, they may be inspired to reduce their concentrate inputs.
