Circunferência escrotal e características seminais em ovinos Dorper e Santa Inês. Repositório Alice
MAIA, M. da S.; SILVA, J. V. C. da; MEDEIROS, I. M. de; LIMA, C. A. C. de; MOURA, C. E. B. de.
O objetivo desse estudo foi avaliar os parâmetros espermáticos e testiculares de carneiros das referidas raças. Foram utilizados 10 carneiros adultos (cinco da raça Dorper e cinco Santa Inês), criados em regime semi-intensivo na região Agreste do Rio Grande do Norte.

Evaluation of Three Mathematical Functions to Describe the Relationship Between Body Weight, Body Condition and Testicular Dimensions in Yankasa Sheep International Journal of Morphology
Yakubu,A; Musa-Azara,I. S.
Body size and testicular measurements have been found to be important parameters utilized in breeding soundness evaluation. The present study therefore, aimed at determining the relationship between body weight (BW), body condition score (BCS), testicular length (TL), testicular diameter (TD) and scrotal circumference (SC) in 120 extensively reared Yankasa rams (approximately 30 months old) using linear, quadratic and cubic predictive models. Coefficient of determination (R2), Adjusted R2, the estimate of Mallows' Cp, RMSE (Root mean squares error) and the parsimony principle (p=number of parameters) were used to compare the efficiency of the different models. Strong Pearson's correlation coefficients (r = 0.83-0.94; P<0.01) were found between BW, TL,...

Testicular shape and andrological aspects of young Nellore bulls under extensive farming R. Bras. Zootec.
Siqueira,Jeanne Broch; Oba,Eunice; Pinho,Rogério Oliveira; Guimarães,Simone Eliza Facioni; Miranda Neto,Tamires; Guimarães,José Domingos.
Aiming to determine the relationship between the frequency of testicular shape and the andrological aspects in young Nellore bulls, 18,676 animals were assessed. All andrological examinations were performed between the years 2000 and 2008. Animals were classified as able for breeding, able for breeding in natural mating system, unable for breeding and discarded. The testicular shape was classified as long, fairly long, oval-long, spherical-oval, and spherical. The analysis of Pearson correlations was performed for testicular shape with scrotal circumference, testicular volume, progressive motility, sperm vigor, major defects, minor defects and total defects. Testicles with oval shape prevailed (99.61%). It was obseved that 76.34; 66.34; 64.34; 58.33 and...
