Implementación de un plan de manejo genético ovino en la comunidad de Shobol Llin Llin, parroquia San Juan, provincia de Chimborazo.

Abstract

The objective of the research was to implement a sheep genetic management plan in the Shobol llin llin community, province of Chimborazo characterizing and implementing the genetic improvement that would be evidenced with technical management. A descriptive analysis was applied using the measures of central tendency and dispersion to determine if the central data complies with the parameters of the breeds. Samples of 60 sheep and maltese were taken using zoometry that measures phaneroptic variables such as fleece color, eyes, mucous membranes, skeletal problems using observation. In the evaluation of the wool, the field method was used to measure the length of the wick and the number of curls per inch, the zoometric variables are measured in all parts of the animal's body must be in a straight place using the zoometric cane and the tape measure, once the zoometric values are obtained, the zoometric indexes that determine the animal's biotype are evaluated. The following values were obtained for the zoometric variables in sheep and Maltese: height at withers (60.7cm) and (51.26cm); height at rump (58.7cm) and (49.17cm); body length (88.5cm) and (79.65cm); thoracic perimeter (89.63cm) and (85.26cm) and face width (10.53cm) and (7.57cm); face length (13.73cm) and (10. 52cm), among others, obtaining dolichocephalic and longilinear animals. A double rotation crossbreeding system was established using pure breeds on the paternal side such as Texel and Poll Dorset, if it will have a reproductive cycle of 8 months, The technical management was implemented based on feeding, management and sanitation, concluding that the Shobol animals are of wool biotype and were crossed with Poll Dorset and Texel breeds to have meat breeds. It is recommended that the research serves as a basis for producers in the parish of San Juan.
