Life cycle efficiency of beef production. 6. Relationship of cow efficiency ratios for progeny slaughtered to growth, condition, fertility and milk production of the dam



Life cycle efficiency of beef production. 6. Relationship of cow efficiency ratios for progeny slaughtered to growth, condition, fertility and milk production of the dam



Journal of Animal Science 60(1): 69-81



Weights and individual feed intakes of 160 beef, dairy and beef X dairy dams and their progeny were used. Efficiency was expressed as ratio of output to input, where output included relative values for slaughter weights, carcass weights and trimmed wholesale cut weights of progeny and weight of the dam, and inputs were pre- and postweaning feed intake of progeny plus lifetime feed intake of the dam.
