Abstract
    In the current research, aspects that may influence meat production were analyzed, and in order to obtain results close to reality, the research team considered the elimination of some factors of influence that could distort the way of expressing the characters under evaluation. Therefore, estimating the heterosis effect for meat production was based on a well-developed plan in which experimental treatments were similar.
    For the accuracy of the data, the fattened goat comes from the same calving season and, during the lactation, period, the young goat was kept together with the goat mothers in common breeding chairs and the weaning was done at the age of 80 days. When constituting batches for fattening, weight was also taken into account, being accepted only individuals with similar body development, the admitted differences being of ±2 kg.
    The analysis of the heterosis effect pattern for the characters referring to the cut portions in the casing, respectively for the neck and back, the head of the chest, the crotch and for the jig, the heterosis effect determined has higher values at the Anglonubiana half breed and the statistical significance for the proportion of the jig is significant for the statistical threshold of more than 5%. On the basis of these data, it may be recommended that when the production of goat meat is prioritized, it can be used the industrial crossbreeding for the Anglonubiana male goats.
