Abstract

Feeder calf classes (sex, age, weight and condition) and cull sales were simulated for cow-calf herds that differed in genotypes for size and milking potential. The Texas A&M Beef Cattle Simulation Model was used to simulate animal performance (growth rates, fertility and herd composition) based on availability, digestibility and crude protein content of Coastal bermudagrass forages typically available in Central Texas. Estimated pricing equations were used to value each animal based on month and year of sale, sex, weight, condition, slaughter steer and grain prices. Revenues, costs and net returns were calculated for 1972 through 1981 for two different resource situations. Results indicated higher net returns to land and management and lower variance were generally associated with increased cow size and decreased milking potential. Net returns to land, livestock, labor and management were highest for large, medium-milking cows, but lower variances were associated with decreased milking potential as well as increased cow size. Although the purpose of the study was to compare the economic viability of the 18 cow types and weaning options, perhaps of equal importance was the finding that not one of them yielded a positive average net return to land and management for the 10-yr period, 1972 through 1981.
