Abstract

THE PURPOSE OF THIS WORK WAS TO STUDY INCUBABILITY INDICATORS SUCH AS FERTILITY, HATCHING AND EMBRIONARY DEATH OF NATIVE HEN EGGS, AS WELL AS EFFICIENCY FOOD INDICATORA: FOOD INTAKE, WEIGHT GAIN AND FOOD CONVERSION. TO ACHIEVE THIS, EGGS FROM RURAL COMMUNITIES FROM THE MORELIA AND TARIMBARO MUNICIPALITIES IN THE STATE OF MICHOACAN WERE COLLECTED. FROM 1 162 EGGS COLLECTED, THE RESULTS WERE: SELECTED EGGS FOR INCUBATION, 56.8% (100%); DISCRIMINATED EGGS, 43.2%; EARLY EMBRIONARY DEATH, 6.7%; LATE EMBRIONARY DEATH, 8.3%; WITH BROKEN VITELUS, 4.5%; PECKED NOT HATCHING, 5.7%, AND TOTAL FERTILITY 82.2 %. THE AVERAGE FOOD INTAKE AT 4, 8 AND 12 WEEKS OF AGE WAS 34, 48 AND 72 G PER ANIMAL BY DAY, AND THE EFFICIENCY FOOD WAS 3 650:1, 3 250:1 AND 4 030:1 ON THE SAME AGE, RESPECTIVELY. INCUBABILITY PROBLEMS OF NATIVE HEN EGGS RESULTED IN BAD QUALITY SHELL, EMBRIONARY DEATH, INFERTILITY, AND A BETTER INDEX OF EFFICIENCY FOOD AT 8 WEEKS OF AGE.
