Description
Previous economic analyses of grazing intensity studies have related profit to stocking rate. However, no information is available on the relationship between profit and kg standing herbage ha-1. In this paper the objective is to relate profit ha-1 to standing herbage. Coastal bermudagrass continuously grazed with beef steers at four grazing pressures is used as an example. Average daily gain and animal grazing days ha-1 were linearly related to standing herbage (r = 0.95 and 0.99). The resultant regression equations were used to relate beef gain ha-1 to standing herbage. This function in tum was used to relate profit ha-1 to standing herbage. The level of standing herbage which resulted in maximum profit increased with a decrease in the difference between selling and buying price kg-1 animal livemass, and can be below or above the level which results in maximum gain ha-1. Maximum profit increased with the difference between buying and selling prices kg-1 animal livemass and with an increase in the absolute values of buying and selling prices. The method of analysis presented here may serve as a useful alternative or supplement to economic analysis of grazing intensity studies that are based on stocking rate.
