إضافة وسم | الملخص: | This research project was conducted at the Salache Academic Experimental Center of the Technical University of Cotopaxi, whose objective was to evaluate morphometric and productive characteristics of subpopulations of breeding female guinea pigs. For wich the research evaluated 30 animals, which are divided into three groups of 10 animals representing the subpopulations: Centro Experimental Académico Salache (CEASA), Granja Matilde and the Escuela Superior Politécnica de Chimborazo (ESPOCH) respectively, the duration of the project was 7 weeks where the following variables were evaluated: loin length, head length, thoracic perimeter, total body length, type of coat, coat color, number of toes on the forelimbs and hind limbs, presence of swirls on the forehead; also initial weight, final weight, weight gain and feed conversion in order to establish a relationship between morphometric and productive characteristics. The information analysis was based on descriptive statistics, in addition to the applying of Pearson's correlation. When analyzing the morphometric measurements of each subpopulation, it was deduced that ESPOCH obtained the best results in loin length (20.47 cm) and total body length (28.28 cm). Within the phenotypic characteristics, 100% of the animals were type 1; 90% of the animals had 4 toes on the forelimbs and 3 toes on the hind limbs. In the CEASA subpopulation, there are 30% of animals whit presence of swirls; for the subpopulation ESPOCH there is 50% of both the presence of swirls on the forehead; no animal presented swirls around body. The ESPCOH subpopulation obtained better results in term of weight gain and feed conversion, with a final weight of 665.4 g, a weight gain of 7.86 g/day/animal and a feed conversion of 3.75. Finally, it is mentioned that both the CEASA subpopulation and the ESPOCH subpopulation showed a high positive correlation with morphometric measurements and final weight, except for thoracic perimeter. While only the Granja Matilde subpopulation obtained the parameter of small head, with low negative correlation (r: -0.135). Therefore, it can be concluded that the ESPOCH subpopulation has been able to adapt to the environmental conditions of Salache and to the feeding of CEASA, with the best results in both morphometric and productive characteristics, obtaining better values than the animals belonging to the CEASA subpopulation. |
