A series of digestion trials was conducted in order to determine the minimum requirements for growth, maintenance, and milk production of dairy cattle under tropical conditions. The growth requirements were determined by using the following equation: Y = 29.023 X — 3,547. This equation was determined by using heifers weighing from 495 to 712 pounds. The requirement varied from 10.82 to 17.12 therms. The maintenance requirements can be determined by solving the equation: Y = 38.76 X — 20,576.60. The cows used to determine this equation weighed from 701 to 1,018 pounds. The therm requirements varied from 6.594 to 18.92. The production requirements above maintenance were studied also and the equation: Y = 319.3719 X + 7,131.90 was worked out, ...
