Selection indexes to maximize net income for egg laying chickens were constructed with information on egg mass output, body weight and individual feed records. Relative selection efficiencies were then compared with different kinds of information in the index. If the genetic variation in feed consum
The value of individual feed consumption records to improve net income through genetic gain was investigated in an egg-type breeding operation. Genetic and phenotype parameters were estimated for body weight, egg mass and feed consumption on 788 layers from two pure lines and 1120 reciprocal crosses
