Live Weight and Milk-Energy Yield in British Goats

E. E. Ormiston1 and E. E. Ormiston

Illinois Agricultural Experiment Station, Urbana

ABSTRACT

This article deals with 318 records of goats in two-day milking competition at the London Dairy show. The milk-energy yield, FCM, ranges from 1.5 to 17.2 pounds per day. Live weight, W, ranges from 88 to 250 pounds. The correlation between W and FCM is 0.57. In the power equation regression, FCM = aWb, b = 0.91.

Attempting to bring the data into line with FCM for the first 8 months of lactation and live weight measured within 31 days after kidding it appears probable that b in the regression FCM = aWb may be safely taken at unity. That is, milk-energy yield in well-developed milch goats tends to be proportional to live weight.
