LE I L9 EXAMINATION OF THE DEMAND FOR AUCTION MARKET SERVICES IN THE NORTH CENTRAL PIEDMONT Animal Populations. Figure 1 presents a map of the North Central Piedmont area including a circle with a 50 mile radius around Hillsbprough, N.C. incribed on it. Table 1 presents 1986 estimates of numbers of milk cattle, beef cattle, and all hogs for the area enclosed by the circle. Table 2 presents 1986 sales of animal units for the five major auction markets within the enclosed area. TABLE 1. Animal populations for the North Central Piedmont area, by-animal specie, 1986.

Under a stable herd size, the calving rate is a good estimate of the number of animals sold in any one year. Milk cows calving rate is .85, beef, .75. Flogs includes numbers of breeding swine, feeder pigs and top hogs. The state proportion of hog inventory which is market hogs and pigs is .855. Since market .hogs and pigs are produced twice a year, yearly output from hog inventory is twice the number of hogs and pigs Horses includes adults and foals. b One animal unit is one cow,, one calf, two top hogs or sows, or six feeder pigs. Horses are not included. Since the inventory numbers do specify of hogs by age, it was assumed that the proportion of feeder pigs to mature hogs in the population was the same as were sold through the five auction markets in the area. The resulting hog and pig inventory number was converted to animal units by dividing 5.25 into the inventory number. L1 �j
