Caracterização pelvimétrica de matrizes caprinas anglonubianas / Pelvimetric characterization of anglo nubian goatdares / Caracterización pelvimétrica de cabras de raza anglonubia

Atualmente, poucos estudos se dedicam a pesquisas mais aprofundadas de aspectoselementares da pelvimetria, sendo estes, ainda mais escassos com a espécie caprina enestesentido, o presente estudo tem como objetivo caracterizar as medidas externas corpóreasdematrizes caprinas e de sua pelve. Foram utilizadas 30 matrizes caprinas da raça Anglonubianaem idade reprodutiva, manejadas em sistema intensivo, pertencentes ao setor decaprinocultura da Universidade Federal do Piauí (UFPI), Campus Professora CinobelinaElvas (CPCE), Bom Jesus, Piauí, Brasil. Durante todo o ciclo produtivo, foramrealizadasmensurações pélvicas das matrizes durante a gestação e no pós-parto, suas medidas corporaise peso vivo. As análises estatísticas foram realizadas pelo Statistical Analysis Softwareabrangendo análise discriminante, correlação, regressão e comparação de médias. Osresultados obtidos para as características de AC (altura de cernelha), CC(comprimentocorporal), PT (perímetro torácico), BII (biilíaca externa), BISQ (biisquiática externa) e ILIOQ(ilioisquiática externa) apresentaram um baixo coeficiente de variação (C.V), o que demonstrauma estabilidade do rebanho com relação a essas características, ocorrendo poucas variaçõesentre os animais. Não foram verificadas diferenças significativas para as medidas de Biilíacaea Ilioisquiática externas com relação ao estágio fisiológico. Já com relação a Biisquiática, foi observado um aumento durante a gestação. De acordo com os dados observados, nãoocorreram diferenças significativas entre as características avaliadas entre cabras primíparasemultíparas. A incorporação de bancos de dados com as medidas corporais e pélvicas de cabrasauxiliam no desenvolvimento de programas de melhoramento genético de diferentes raçascaprinas, reduzindo a ocorrência de eventos de distocia e /ou dificuldade ao parto de modogeral. As amostragens foram incorporadas em um banco de dados, que está sendo construídopara controle e análise genética dos animais do Colégio Técnico de BomJesus, Piauí. Asinformações de produção e reprodução do rebanho também estarão disponíveis nesse bancode dados.(AU)

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

Los resultados obtenidos paralascaracterísticas AC (altura a la cruz), CC (longitud corporal), PT (circunferencia torácica), BII(bilia externa), BISQ (bisquial externa) e ILIOQ (iliosquiática externa) mostraronunbajocoeficiente de variación (C.V), lo que demuestra una estabilidad del rebaño en relaciónaestascaracterísticas, con pocas variaciones entre animales. No hubo diferencias significativas paralas medidas externas Bilíaca e Ilioisquiática en relación al estadio fisiológico. Biischiatica, por otro lado, se observó que aumenta durante el embarazo.

Correlations between body measures with live weight in young male goats

Data analysis in goat production, such as those related to body and scrotal measurements, indicate the productive and reproductive animal development. The current study aimed to evaluate the correlations between thoracic perimeter (TP), body length (BL), body compacity (BC), body volume (BV), and scrotal circumference (SC) with body weight (BW) in young male goats of Saanen and Boer breeds. It was used 38 Saanen and 24 Boer male goats, with age average of 7.2 ± 2.0 months. Thoracic perimeter and body length measurements were obtained using a tape measure (cm) and the live weight (kg) a mechanic scale. The variables body compacity (BC) and body volume (BV) were calculated using the equations: and . Boer breed showed live weight and body compacity higher than Saanen breed (p < 0.05). Regarding correlations between biometric measurements and body weight, we did not find any statistical differences between the breeds (p > 0.05). The scrotal circumference presented the lowest association with body weight (p < 0.05). However, all biometric measurements showed highly significant correlations with live body (p < 0.01). In conclusion, thoracic perimeter was the main measure of body weight predictor, considering efficiency and practical aspects.(AU)
