Effect of plane of nutrition and composition of the diet on the economic return from dairy cows, productive life and reproduction: 1935 to 1954, Favrholm



Effect of plane of nutrition and composition of the diet on the economic return from dairy cows, productive life and reproduction: 1935 to 1954, Favrholm



Fors<o>gslab. K<o>benhavn Beretn, 285, 168



In this 19-year-long experiment, plane of nutrition was adjusted as follows: normal, 0.4 production feed unit (F.U.) and 60 g. digestible true protein per kg. 4 per cent. milk; low-plane, 0.33 F.U. and 50 g. protein; high-plane, 0.476 F.U. and 71 g. protein. Within the normal and high groups the proportion of succulent fodder was varied so that part had 4 F.U. roots and the remainder 5 F.U. roots and 2 F.U. silage. The low-plane groups had 4 F.U. roots and all had 1 F.U. each of hay and straw.
