Abstract/OtherAbstract:
The present study aimed to compare testicular histology and the testicular cell population as well as spermatogenic efficiency in goats with different scrotal conformations. Eighteen goats were divided into 3 groups: Group I - goats without bipartition of the scrotum, Group II - animals with bipartition of the scrotum up to 50% of the testicular length, Group III - goats with scrotal bipartition more than 50% of the testicular length. In goats in Groups I, II and III, the values for the volume density of seminiferous epithelium were 68.9±0.6%, 71.5±2.8% and 73.4±4.7% (P<0.05), the height of the seminiferous epithelium were 60.2±4.9μm, 61.0±5.0μm and 73.1±6.6μm (P<0.05), total length of seminiferous tubules found for Groups I, II and III were 2091.9±27m, 2172.5±24.1m, and 2340.1±14m (P<0.05), number of Sertoli and Leydig cells were 1.8±0.4×10(9) and 1.4±0.1×10(9), 2.2±0.4 and 2.2±0.7×10(9), and 2.5±0.1 10(9) and 2.3±0.5 10(9) (P<0.05) and daily sperm production observed were 2.1±0.3×10(9), 2.8±0.4×10(9), and 3.1±0.7×10(9) (P<0.05). In conclusion, goats with greater scrotal bipartition have a greater capacity to produce reproductive cells that is reflected in a greater reproductive potential.
