Extract

Two experiments have compared the effects of forages or concentrates offered to dairy cows, continuously stocked in late Summer at a low stocking rate in Experiment 1 or a higher stocking rate in Experiment 2.

In Experiment 1 (July - October 1984) 20 Spring calving British Friesian cows were allocated to a Latin square design with four, three week periods and four treatments, a control group, grazing only (TO), grazing with 5 kg dry matter fresh lucerne per day (TL), grazing with 5 kg dry matter hay per day (TH) and grazing with 4 kg DM concentrate per day (TC). In Experiment 2 (August -October 1985) 24 cows of similar calving dates were used in an incomplete Latin square design lasting eight weeks to compare treatments TO, TL, TS and TC where silage (TS) replaced hay. All supplements were offered for 1 hour after each of two milkings per day.
