Abstract

CHACUR, M.G.M. et al. Body morphometry, semen characteristics, seminal proteins and testosterone in sambar deer (Cervus unicolor) in captivity. Arq. Bras. Med. Vet. Zootec. [online]. 2014, vol.66, n.5, pp.1392-1400. ISSN 0102-0935.  http://dx.doi.org/10.1590/1678-6977.

The aim of this work was to study the body morphometry, semen characteristics, seminal plasma protein profile in SDS-PAGE and serum testosterone concentration in Sambar Deer (Cervus unicolor), in captivity in the breeding season (spring). Four males aged between 12 and 36 months were assessed in four moments with intervals of seven days with body weight (60.5 to 89.0kg), body mass index (93.07 to 126.56kg/m2), ejaculate volume (0.50±0.35mL to 0.75±0.28mL), sperm motility (87.75±4.78% to 90.00±7.07% ), total defects (17.25±5.81% to 47.72±17.55%), serum testosterone (6.43±4.33 ng/dL to 166.00±64.48ng/dL) and seminal plasma proteins with bands between 7.6 and 142 kDa. The characteristics of ejaculates did not differ (P>0.05) among ejaculates (1st, 2nd and 3rd). There were differences (P<0.05) for sperm defects elevation on the fourth ejaculate. In seminal plasma 16 to 27 protein bands between 7.6 and 142 kDa were identified. In conclusion, sperm quality was satisfactory in the spring and the stress of successive contentions decreased sperm quality. Also, there is influence of age upon serum testosterone concentration which was higher in deer at 36 months.
