“…They were lower than (23.3-24.63cm) reported by Pant et al (2008). The value for initial scrotal length (7.88-8.33cm) were also lower than (16.00-16.61cm) obtained by Campos et al (2003) and were not significant (p>0.05). The differences in the initial scrotal circumference and initial scrotal length may be due to breed and age of the animal used for the experiments.…”

“…The goats with a high level of scrotal bipartition demonstrated higher values of scrotal perimeter and testicular length in the dry year period, an observation also made by Almeida et al (2010). Similarly, Villar Filho et al (1993) and Campos et al (2003), concerning morphometrical investigation of male genital organs in dry and rainy periods, suggested an interference of season on the size of the organs, whereas Santos & Simplício (2000) veriϐied the scrotal and testicular response to the increased thermal stress, induced by an insulating bag positioned over the scrotum. Moreira et al (2001) carried out a study in rams, comparable to the goat, observing that the increase on the environment temperature promoted a negative inϐluence correlation on the scrotal circumference and testicular length.…”

Goat scrotal-testicular biometry: Influence of the season on scrotal bipartition

et al. 2011

RESUMO.-[Biometria escroto-testicular em caprinos: inϐluência de período do ano na bipartição escrotal.]Objetivou-se neste trabalho avaliar a biometria escroto-testicular em caprinos com escroto simples e bipartido, criados no Estado do Piauí, Brasil, nos períodos seco e chuvoso do ano. The scrotal-testicular biometry was evaluated in goats raised in Piaui state, Brazil, presenting different levels of scrotal division, in rainy and dry periods of the year. For this study, eighteen male goats at mating age were accomplished and arranged into three groups (6 animals each), obeying the classiϐication as goats with no scrotal bipartition (GI), goats showing scrotal bipartition up to 50% of testicular length (GII), and goats with more than 50% of scrotal bipartition (GIII). The biometry of the scrotal-testicular was made evaluating the scrotal length (SL), scrotal circumference (SC), testicular length (TL) and testicular volume (TV). The results were evaluated following the variance analysis (ANOVA) and the SNK test applied on the average comparisons. The analysis of the data demonstrated high values, in dry and rainy periods, of SC (24.63cm/ 26.97cm), SL (16.61cm/ 18.24cm), TL (5.32cm/ 5.93cm), TV (173.81cm 3 / 203.01cm 3 ). This supports the hypothesis of the inϐluence of the period of the year and of the scrotal bipartition on the scrotal-testicular biometry in goat.INDEX TERMS: Goats, scrotal bipartition, biometry, year-periods variability.to testicular) e o grupo III (bipartição escrotal superior a 50% do comprimento testicular). A biometria escroto-testicular consistiu do comprimento escrotal (COE), circunferência escrotal (CE), comprimento testicular (CT) e volume testicular (V). Os resultados foram submetidos à análise de variância (ANOVA), seguido do teste SNK para comparação das médias. Os dados mostraram que os animais do grupo GIII apresentaram, no período seco, os valores de CE, COE, CT e V de 24,63cm, 16,61cm, 5,32cm, e 173,81cm³, respectivamente e de 26,97cm para CE, 18,24cm para COE, 5,93cm para CT e 203,01cm³ para V, no período chuvoso. Todos esses valores foram superiores (p<0,05) aos encontrados para os animais dos demais grupos. Conclui-se que o grau de bipartição escrotal e o período do ano interferem na biometria escroto-testicular de caprinos. TERMOS DE INDEXAÇÃO: Caprinos, escroto bipartido, biometria.

“…Among the ovine breeds exploited in the Northeast, the Santa Ines has the highest expression due to the size, production of matrices for milk and because the reproducers are very used at intersections schemes with native animals and exotic breeds, besides the fact that this breed is well adapted to the region (Oliveira & Lima 1994, Nunes et al 1997. Campos et al (2003), Teodoro et al (2013) describe that there is significant influence of ambient temperature on the biometry of the reproductive organs, and in the dry season the values decrease considerably. According to Assis et al (2008), the testicular biometry is considered an important factor of evaluation in sheep due to its high correlation with sperm production and reproductive performance as well as production characteristics, such as body development transmitted to offspring.…”

Effect of racial crossing on the scrotum-testicular biometry in sheep submitted to scrotal insulation

et al. 2017

The objective of this study was to evaluate the effect of the racial crossing on scrotum-testicular biometric characteristics of four sheep Santa Ines and four crossbred (Santa Ines x Dorper) submitted to scrotal insulation, following the return of these characteristics to values previously reported. For this, two measurements were made regarding the scrotal circumference (SC), length (L) and testicular width (W) before treatments. The testicular volume (V) was calculated by the formula V=2 [(r2) x π x H]. The pouches were made with double-layer plastic, internally lined with cotton, and fixed around the spermatic funiculus and scrotum with adhesive tape and bandage remaining in this position for seven days. Measurements were made every seven days, totaling 15 measurements throughout the experiment. The data were submitted to analysis of variance (ANOVA) to a randomized block design with two blocks, 15 treatments and four replications. The variables analyzed were subjected to Dunnett test at 5% probability, to compare the values obtained before and after insulation. For comparison between the breeds, the variables were submitted to Tukey test at 5% probability. All animals studied suffered significant influence (P<0.05) after scrotal insulation, but Santa Ines returned to the values previously observed in a shorter period than the crossbred. In summary, sheep Santa Ines have a higher resistance than crossbred animals when subjected to thermal stress induced by scrotal insulation.
