PELVIMETRIC CHARACTERIZATION OF ANGLO NUBIAN GOAT DARES

Abstract

Currently, few studies are dedicated to more in-depth research of elementary aspects of pelvimetry, which are even scarcer with the goat species and in this sense, the present study aims to characterize the external body measurements of goat matrices and their pelvis. Thirty Anglonubian goats at reproductive age, managed in an intensive system, belonging to the goat sector of the Federal University of Piauí (UFPI), Campus Professora Cinobelina Elvas (CPCE), Bom Jesus, Piauí, Brazil, were used. During the entire production cycle, pelvic measurements of the sows were performed during pregnancy and postpartum, their body measurements and live weight. Statistical analyzes were performed by the Statistical Analysis Software covering discriminant analysis, correlation, regression and comparison of means. The results obtained for the characteristics of AC (height at the withers), CC (body length), PT (chest circumference), BII (external biiliac), BISQ (external bischial) and ILIOQ (external ilioschiatic) showed a low coefficient of variation (C.V), which demonstrates a stability of the herd in relation to these characteristics, with little variation between animals. No significant differences were found for the external Biiliac and Ilioischiatic measurements in relation to the physiological stage. Biischiatica, on the other hand, was observed to increase during pregnancy. According to the observed data, there were no significant differences between the characteristics evaluated between primiparous and multiparous goats. The incorporation of databases with body and pelvic measurements of goats helps in the development of genetic improvement programs for different goat breeds, reducing the occurrence of dystocia events and/or delivery difficulties in general. The samples were incorporated into a database, which is being built for control and genetic analysis of the animals Colégio Técnico de Bom Jesus, Piauí. Herd production and reproduction information will also be available in this database.
