Aim of this study was to select superior rams by assessing their scrotal size and quality semen. In ten indigenous Bangladeshi rams, the body weight, circumference, volume increased with age (P<0.05). Body weight at 381-410 days (13.6 ± 1.5 kg) higher than 169-200 (10.2 0.1 201-230 (10.4 1.2 (p<0.05). Scrotal circumference 381 - 410 (19.1 0.3 cm) (p<0.05) 169 200 (17.2 cm), 201 230 0.6...

Quantitative microscopic structure of testis in adult Arabian rams, raised under closed grazing system in Khuzestan province of Iran, was studied in four seasons over a one year period. For this purpose, thirty adult rams were randomly selected and the live weight and scrotal circumference of rams were recorded. At the beginning of each season, among the study group, four rams were randomly sel...

Aggressive angiomyxoma (AAM) is a rare mesenchymal benign myxoid tumor, characterized by locally infiltrative nature and high recurrence rate. AAM occurs almost exclusively in adult females, arising from the soft tissue of the pelvic region: to our knowledge, only 43 cases occurring in men have been reported. We report a case of massive recurrence of scrotal AAM in a 46-year-old obese man, who ...

Independent of whether natural mating or artificial insemination is used for breeding, libido (sex drive) is evidently crucial to reproductive competence in all male meat animal species. Breeding goat bucks vary in their levels of libido; therefore, there is a need for the development of a predictive standardized test for estimating sex drive. The objective of this study was to evaluate libido ...

Reproductive traits were measured for 234 bulls and 1184 heifers from matings of three dam breeds (Angus, Hereford, and MARC III) with six sire breeds (Angus, Hereford, Brahman, Boran, Tuli, and Belgian Blue) from the Germ Plasm Evaluation (GPE) Program at Roman L. Hruska US Meat Animal Research Center. Male traits were yearling scrotal circumference (YSC), height (YH), and yearling BW; age at ...

Records for yearling scrotal circumference (SC; n = 7,580), age at puberty in heifers (AP; n = 5,292), age at first calving (AFC; n = 4,835), and pregnancy, calving, or weaning status following the first breeding season (PR1, CR1, or WR1, respectively; n = 7,003) from 12 Bos taurus breeds collected at the Meat Animal Research Center (USDA) between 1978 and 1991 were used to estimate genetic par...

There is limited genetic information relating calving difficulty and body weights to other productive and reproductive traits. Such information is useful for specifying selection criteria and for predicting economic consequences of selection. Genetic, maternal, and environmental covariances of six productive and reproductive measurements with calving difficulty, birth weight, 200-d weight, and ...
