In order to compare weigh and internal quality of egg of four Venezuelan breeding hens, it conducted an experiment in the LaboratorioSecciUn de Aves (FAGROUCV). It provided a ration between 80 g and 110 g of food/bird (depending on age). Health program included immunization against Newcastle and Infectious Bronchitis diseases. Were recorded 8.689 egg weights and 3.142 eggs were used for internal quality; calculating the Haugh units. Variance analyses were performed considering a design completely randomized, including breed and age of hen in week effect in the model. To analyze internal quality of the egg according to the age of the hen, only was considered this last effect. Lineal regression of egg weight over week of age of the hen was estimated. Were realizedt � Student test with a signi˚� cance level of 0.05. There were differences (P<0.05) of egg weight between breeds. FAGROUCV was higher (56.4 g), without differences for internal quality. Egg weight increased 0.23 g over av...
