Stocking rate

Curll, M.L., Wilkins, R.J., Snaydon, R.W. Shanmugalingham, V.S. (1985) The effects of stocking rate and nitrogen fertilizer on a perennial ryegrass -white clover sward. Grass and Forage Science, 40, 129-40. 

In the conventional herd, concentrate use has decreased and stocking rate has increased, presumably because of the increased use of nitrogen fertiliser (Table 3.2). Wilkinson (1984) presents data to... 

Table 3.2 Concentrate use and stocking rate in the conventional herd.

The assumptions underlying the target organic stocking rate are ... 

The corresponding target stocking rate for a 450 kg Guernsey is 2.4 cows per ha. 

July to housing. For a dairy farm with half site class 2 fields and half site class 3 fields, yielding 12 t dry matter per ha per annum and utilising this with an efficiency of 67%, annual stocking rate would be 1.9 dairy cows per ha. With a spring to autumn stocking rate ratio of 1.5 1, stocking rate from turnout to mid-July would be 2.28 cows per ha and from mid-July to October would be 1.52 cows per ha.
