Résumé
The aim was to study pregnant cervus in captivity, to obtain body morphometric data, serum progesterone concentrations, and pH of the vagina. Females of cervus (Cervus unicolor), (n=8) between 2 and 3 years old were used in November during breeding season. After sedation, in one collection, the following was measured: body weight 54.50 ± 18.70kg, body length 1.21 ± 0.16m, height at withers 0.75 ± 0.08m, thoracic perimeter 0.84 ± 0.12m, and body mass index 97.32 ± 10.50kg / m2. After sedation, blood samples were collected to measure progesterone concentration by radioimmunoassay and the use of an indicator tape to obtain the pH of the vagina was performed eight times at four day intervals in the eight females, in a total of 64 samples for each exam. Data were analyzed, and significance was at 5%. There were no differences (P> 0.05) between measurements for serum progesterone concentrations and pH of the vagina. The correlations between body weight, progesterone, pH, and body mass index were not significant (P> 0.05). There was no significant oscillation of progesterone concentration and pH of the vagina in the pregnancy period studied.

Objetivou-se estudar a morfometria corpórea, as características do sêmen, o perfil proteico do plasma seminal em SDS-PAGE e a concentração sérica de testosterona em cervos-sambar (Cervus unicolor), criados em cativeiro, na estação reprodutiva da primavera. Quatro machos com idades entre 12 e 36 meses foram avaliados em quatro momentos, com intervalos de sete dias, com peso corpóreo (60,5 a 89,0kg), índice de massa corporal (93,07kg/m2 a 126,56kg/m2), volume do ejaculado (0,50±0,35mL a 0,75±0,28mL), motilidade espermática (87,75±4,78% a 90,00±7,07%), defeitos totais (17,25±5,81% a 47,72±17,55%), testosterona sérica (6,43±4,33ng/dL a 166,00±64,48ng/dL) e proteínas do plasma seminal com bandas entre 7,6 e 142kDa. As características dos ejaculados não diferiram (P>0,05) entre as três primeiras colheitas. Houve diferença (P<0,05) para os defeitos espermáticos com elevação na quarta colheita. No plasma seminal de cada cervo, foram identificadas de 16 a 27 bandas de proteínas entre 7,6 e 142kDa. Conclui-se que a qualidade espermática foi satisfatória na primavera. O estresse das contenções sucessivas causou queda da qualidade espermática. A idade influi na concentração sérica de testosterona, a qual foi maior nos cervos aos 36 meses...
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...
