"EVALUATION OF PRODUCTIVE PARAMETERS OF CHIAPAS SHEEP IN THE MUNICIPALITY OF TEOPISCA UNDER A SEMI-INTENSIVE SYSTEM" (Atena Editora)

Abstract

In Chiapas there is a diversity of sheep breeds, however, there is a wool sheep biotype in the Altos and Sierra regions "the Chiapas sheep" has a double function in the Tzotzil communities, which is the production of manure and the production of wool. The present investigation had as objective the evaluation of the productive parameters of the Chiapas sheep of CETNO-UNACH in the municipality of Teopisca in the Tsotsil-Tseltal zone. The study subjects were 168 specimens (59 Males and 109 Females) with different age range (1-8) and phenotype (39 White, 92 Black and 37 Brown), they were fed during the months of August-October based on stubble, ground corn, mineral salt, soybean paste; The variables of: live weight, age, body condition, wool length (long and short wool length, presence of heterotypic fibers, washing performance) were analyzed. Weight gain at the end of the study reached an average weight of 0.8 kg total. The length of the wick in the males was found a general average of long-thick fibers of 10.1 ± 1.4 cm and short-thin fibers of 5.7 ± 0.8 cm. In the length of the wick in the females, according to the phenotypic variety, I present a general average of long-thick fibers of 10.4 ± 0.75 cm and short-thin fibers of 6.1 ± 0.45 cm. The total average unwashed weight was 41.4 ± 9.8 gr and a washed weight of 34.5 ± 7.6 gr, obtaining a yield of 84.3%.
