Caracterización zoométrica, parametría productiva y reproductiva de dos ecotipos de cuy criollo provenientes de la provincia de Azuay y Cañar a través de la conformación de núcleos exsitu y su comparación con una línea mejorada

Abstract

The research was made out in the Irquis experimental farm of the University of Cuenca, the purpose of these research was to determ the zoometric features, productive and reproductive pattern of two ecotypes of guineapigs from the Azuay and Cañar province through the formation of groups (exsitu) to be able to make a later comparition with the peruvian guineapig. A total of 90 animals were studied, there were 3 different groups, each group contain 30 animals. The study was made in cages, the animals were fed with forrage and water. For the investigation was use descriptive estadistic and ANOVA with 5%, Duncan test, as well as Kruskal- Wallis and Mann- Whitney test. In the zoometric evaluation many variables were considered: birth weight, weaning, during 90 days: measurment of body, foot ears, head and height, having as result 103,2g- 112,6g; 187,1g- 200,5g; 473,7g- 604g; 20,9cm- 22,8cm; 4,2cm- 4,5cm; 6,2cm,- 6,7cm; 2,9cm - 3,1cm;6,0cm- 6,5cm for Azuay and Cañar. The straight coat type 1 and overo combination were the most notorious of the study, on ears and eyes the black color was the one that stand out the two ecotypes; the formula 4-3 was the most common in both ecotypes, the examination was made on the paws of the front limb and rear limbs. The size and weight measurment of the litter at birth and weaning were: 2,2- 2,6 baby guineapigs, 219,3g- 287,6g; 1,9- 2,4 baby guineapigs, 354g- 482.4g. The fertility percentage was 92% and 96%, meanwhile the mortality before and after weaning was 7 and 6% for the Cañar ecotype and 7 and 15% for the Azuay. The gaining weight, consumption and conversion registered: 285.3g and 407.1g, 2981.9g and 2893.4g, 11.1 and 7.4 first data for Azuay and second for Cañar.
