| Sumario: | Backyard production systems use native hens along with another type of animals that are slow-growing and have proven hardiness along with different plumage colors (buff, red, gray, etc.). This second type of bird is generically called "pollo campero". It is necessary to characterize these birds from a structural and productive focus to contribute to its sustainable use. The purpose of this work is to characterize the growth of different maternal Campero INTA chicken populations. The stages of the reproductive cycle were carried out at the Center for Poultry Multiplication of INTA Corrientes, Argentine. Two trials were conducted to study the effect of maternal genotypes Campero INTA (E and T) onto the growth variables. Both populations were housed in three enclosures during the rearing period, each one having a simple repetition of the independent variable so that both populations had 6 replicates. Results are presented as least squares means after analysis of variance using the general linear models procedure of Infostat 2008 program with the genotype as the source of variation. There were no statistically significant differences for body weight and uniformity by genotype. However, the length of tarsus showed differences significant (p <0.05). The values obtained were 93, 83 ± 3,19 and 92,00 ± 2,76 mm for genotypes E and T respectively. These results confirm the discriminating power of the variable length of tarsus to the characterization of these avian genotypes. |
