Evaluación productiva de gallinas de campo de la región sierra del Ecuador

Abstract

In Tunshi Experimental Station of the Superior Politechnical College of Chimborazo located in Licto parish of cantón Riobamba, the productivity of the field hens was evaluated, they come from the following provinces of the sierra region of Ecuador : Pichincha, Bolivar, Loja , Cañar, Tungurahua and Chimborazo. Descriptive statistics was in use in 94 beards, so productive parameters were brought like: Initial average weight: 1508,78 ± 207,62 g. Final average weight: 1502,36 ± 247,61 g .Average weigh profit: 175,26 ± 137,20 g. Average weight loss: - 177,08 ± 157,46 g. As regards egg quality parameter was obtained an average weight of :54,95 ± 5,24 g, average egg mass:48,15 ± 4,68 g. Average width of the egg:42,25 ± 1.36mm. Average egg length:55,40 ± 2,60mm. Average eggshell weight : 6,80 ± 1,11g. Average eggshell thickness: 0,32 ± 0,02 mm. For organoleptic feature a triangular sensory analysis was performed using 6 combination with 3 repetitions. In all 18 tasters took part and the outcome had been submitted to chi-square, there were significant differences between creole egg flavor and commercial egg flavor. It should be noted that rustic hens features represents great value for the conservation of genetic resources, the hens field have demonstrated to have a capacity of adjustment to the environment throughout the time, which ensures good productive performances and It turns out to be interesting for the safety and alimentary sovereignty.
