Evaluación de las características reproductivas de gallinas criollas en la etapa de postura bajo tres sistemas de manejo intensivo, semintensivo y extensivo en el cantón Logroño.

Abstract

In Logroño which is a small city in Morona Santiago, the reproductive characteristics of Creole hens in the laying stage raised under three management systems (intensive, semi-intensive and extensive) were evaluated, with 5 replications distributed in 3 treatments, giving us a total of 15 experimental units, where each experimental unit is formed by 5 birds from 5 to 6 months of age, where the initial weight, final weight, weight gain, egg weight, upper and lower egg diameter, egg production/bird laying percentage and laying percentage/UE % were analyzed. The present work of curricular integration was carried out in the facilities of Juana Brito farm, in Logroño, under a completely randomized block design, which was distributed, and its results were analyzed with the statistical package Infostat and the Tukey test at 0.05. The results showed significant differences between treatments, where the application of the intensive system presented better reproductive responses in final weight with 2.63 kg, a weight gain of 0.37 kg, a laying percentage of 82.22 % and a production of 4.26 eggs/bird, surpassing in these parameters the other treatments evaluated; however, the semi-intensive management system showed the highest economic profitability. It was concluded that the application of the intensive system in the management of Creole hens allowed recording the best weights, weight gain, laying percentage, egg production, so it is recommended to use the semi-intensive system due to its low costs in the constructions and giving an efficient result in the production of eggs for sale.
