Pelvimetria de suínos das linhagens Agroceres e DanBred

Abstract

Umas das principais causas de distocia é a incompatibilidade feto-pélvica. Os problemas reprodutivos associados ao parto predispõem as propriedades produtivas a inúmeras perdas econômicas como: redução na produção de carne, descarte prematuro e despesas adicionais com manejo e veterinários. Esse estudo preliminar foi realizado com o objetivo de mensurar a região pélvica externa e interna de suínos de duas linhagens (Agroceres e Danbred). Foram avaliadas 10 matrizes, sendo cinco de cada linhagem. Mensurações corpóreas foram realizadas com fita métrica e bengala hipométrica, para a mensuração corporal e externa da pelve, e Pelvímetro de Rice, para a mensuração interna da pelve. As médias para as medidas externas da pelve das linhagens Agroceres e Danbred foram respectivamente:

Phenotypic diversity in buffalo cows of the Jafarabadi, Murrah, and Mediterranean breeds

“…In all cases, the anatomical model of the pelvis was similar to an ellipse with vertical major axis, i.e., the birth canal had a lateral flattening. The main advantage of knowing these measures is to avoid fetal-pelvic incompatibility, i.e., large progeny and/or mature cow pelvis with measures smaller than the standard (Araújo et al, 2014). The withers-to-rump ratio and longitudinal pelvic zootechnical indexes were used to classify buffalo cows of the three breeds into similar profiles.…”

“…The animals were kept in a cattle crush so that information regarding their identification could be collected and general body measurements (Bianchini et al, 2006;Mello & Schimidt, 2008), as well as external and internal pelvic measurements (Araújo et al, 2014), could be performed. These measurements were combined to calculate the following indexes for conformity, production suitability (milk and meat), and ethnology (Marchiani Dubuc, 1991;Contreras et al, 2011;Rezende et al, 2014a): anamorphic index (thoracic perimeter squared divided by withers height, multiplied by 100); pelvic index (rump width divided by rump length, multiplied by 100); withers-to-rump ratio (withers height divided by rump height); body index (body length divided by thoracic perimeter); lateral-body index (withers height divided by body length, multiplied by 100); relative body index (body length multiplied by 100, divided by withers height); body capacity index 1 (quotient between weight and body length); body capacity index 2 (quotient between weight and thoracic perimeter); transversal pelvic index (rump width divided by wither height, multiplied by 100); longitudinal pelvic index (rump length divided by withers height, multiplied by 100); and thoracicperimeter-to-withers ratio (thoracic perimeter divided by withers height).…”

Pelvimetry of multiparous Nellore cows in the cycling and early puerperal stages

“…Animals in the early puerperal stage presented larger sacropubic diameter; similar results were found in Guzerá cows by Okuda et al (1994) ( Table 3). The main advantage of knowing these dimensions, measured through pelvimetry, is to avoid fetal-pelvic incompatibility (Araújo et al 2014), i.e., including in the reproduction system animals with incompatible dimensions. According to the Pearson's correlation, the correlations between internal and external pelvimetric dimensions of multiparous cows in the cycling and early puerperal stages were low for most animals, or moderate.…”

“…Four types of pelvimeter can be used in the direct method: the manual pelvimeters of Menissier-Vissac (Derivaux & Ectors 1984) and Rice, and the pneumatic/hydraulic pelvimeters of Krautmann-Litton and Equibov-Litton (Deutscher 1985, Ko & Ruble 1990. Indirect pelvimetry is the correlation between pelvic and body dimensions (Araújo et al 2014). The present work aimed to highlight the importance and practicality of direct and indirect pelvimetry by describing the correlation between internal and external pelvic dimensions of multiparous Nellore cows at different reproductive stages (cycling and early puerperal) and provide data regarding the use of measures of internal pelvic area for studies on this breed.…”

Female squirrel monkeys as models for research on women’s pelvic floor disorders

“…The ischium is grossly excavated and arched ventrally at its caudal end, like that observed in ruminants and pigs. 37,38 Aksel and Abee 39 measured squirrel monkey pelvises using lateral and anteroposterior radiographic projections. Significant differences were subsequently observed between the superior and inferior bi-iliac diameters of females with livebirth neonates (1.84 AE 0.09 and 1.9 AE 0.13 cm, respectively) and stillbirths (1.87 AE 0.08 and 1.92 AE 0.10 cm, respectively).…”
