Abstract Snakes represent a wide and diverse group of species have anatomical particularities, such as the renal sexual segment (RSS), structure located in kidneys formed from hypertrophy urinary ducts nephrons. This study aims at describing histological aspects RSS Boa constrictor , Epicrates cenchria Corallus hortulanus all which are Brazilian snake Boidae family. The reproductive system five male specimens E. three C. two B. were obtained. Tissue samples processed histologically different...
In general snakes show differentiate anatomical, biological and behavioral particularities compared to other species. Basic information about the anatomy, physiology reproductive biology is scarce in several species, making reproduction a challenge. Thus, present work aims evaluate morphological aspects of Corallus hortulanus testes, correlating these findings with environmental factors aspects. The testes three specimens were cut thickness 3μm microtome, stained 1% toluidine blue, photo...

Results showed pattern multiple antibiotics turbidity, which was expected due contaminants. most frequent sul I II (sulfonamides), present all lakes, followed by encoding...
In Brazilian zoos wild felids in captivity are generally fed meat. However, considering the basic nutritional needs of domestic cat Felis catus , beef may be deficient calcium, phosphorus, copper, manganese, vitamins A, D and E, thiamin, folic acid biotin. The aim this study was to determine influence vitamin (A, D, B 1 2 biotin) mineral (calcium, iron, iodine manganese) supplementation on quality semen Jaguars Panthera onca. Between August 1998 1999 eight adult ♂ were offered red meat...
The α-adrenergic agents are known to influence erection and ejaculation, ejaculatory reflex is a primarily α-adrenergically mediated event. This paper aims describe the urethral catheterization technique after pharmacological induction for semen collection in domestic dogs. For dose determination, was performed using increasing doses of dexmedetomidine (5 μg/kg, n = 2; 10 2 15 2) associated 3 mg/kg ketamine six animals. Once established, additional association μg/kg carried out eight After...
Semen samples (n=105) were collected through eletroejaculation from six adult male coatis (Nasua nasua) between January 2007 and December 2008 at Universidade Federal de Mato Grosso Zoo, Cuiabá, Brazil. Mean values were: volume (mL); concentration (sperm/mL); total motility (%); progressive sperm (scale, 0-5); live spermatozoa acrossome integrity primary defects secondary (%). There was high correlation sperm; motility; integrity; concentration. The method for semen collection considered...
Os efeitos das enzimas hialuronidase e tripsina foram avaliados quanto à liquefação, motilidade, vigor integridade do acrossoma, no sêmen de seis macacos pregos (Cebus apella), mantidos na Fundação Parque Zoológico São Paulo. O foi colhido por eletroejaculação, após anestesia geral, a fração líquida imediatamente avaliada. A coagulada tratada com as tripsina, dose 1mg/ml, diluídas em meio 199 (Nutricel, Campinas/SP, Brasil), proporção 1:4 examinada 5 15 minutos. Test t Student utilizado para...
Tree Cerdocyon thous males received different anesthesia protocols: tiletamine-zolazepan (7mg/kg); ketamine-xylazine (12 and 1mg/kg); ketamine-xylazine-atropin (12, 1.0 0.04mg/kg), ketamine-midazolam 0.5mg/kg) ketamine-acepromazine 0.1mg/kg) for semen collection by electroejaculation, testosterone hormonal dosages, fine needle aspiration cytology (FNAC), testicular manual evaluation, biometry caliper ultrassonography (US). The ejaculates collected electroejaculation showed urine...
Assisted reproductive technologies can be viewed as one potential approach for safeguarding wild species. In this study were evaluated the fertility of captivity male jaguar (Panthera onca) and different capacitation media using golden hamster zona free oocyte penetration assay. We used frozen/thawed semen from 3 animals housed at Bosque dos Jequitibas, Campinas/SP, to test Percoll gradient, Swim-up + 1 h incubation (5% CO2 / 38°C), considering spermatozoa head descondensation visualized...
Exogenous gonadotropins frequently are used to stimulate ovarian follicular growth and ovulation in mammalian species, including felids. However, repeated exogenous gonadotropin treatment can result decreased responsiveness due antibody formation. In this study, our objectives were assess the effectiveness of alternating regimens on responses ocelots tigrinas, investigate humoral immune these each species. Females treated four six times with equine chorionic (eCG)/human (hCG) porcine...
The objective was to characterize seasonal changes in serum testosterone concentration, testicular volume and sperm quantity quality captive coatis (Nasua nasua) from Pantanal, MT, Brazil. Sampling done once monthly for 1 y. Mean (± SEM) concentrations (767.37 ± 216.2 ng/ml) total progressive motility (79.6 3.9%; 3.8 0.3, on a scale of 0 5) peaked July. highest combined testis (10.3 0.4 cm(3)) concentration (403 million 102 sperm/ml) occurred August, at the peak winter breeding season. No...

Several methods of testicular punch biopsy were proposed for obtaining material histologic or cytologic evaluation, but did not received enough clinical acceptance because it was considered to be too traumatizing. The fine Needle Aspiration (FNA) is a useful, simple and fast method obtain samples from tissues. Regarding the importance FNA in wild animals, this technique tried captive adult jaguar (Panthera onca) aiming evaluation possible causes infertility. Using needle disposable syringe,...
Biotecnologias reprodutivas aplicadas a espécies selvagens, como inseminação artificial, fertilização in vitro e transferência de embriões, são vistas um potencial caminho para proteção das ameaçadas extinção. Devido isso, o objetivo deste estudo foi avaliar fertilidade do sêmen congelado onças pintadas (Panthera onca) meio capacitação espermática usando ensaio penetração em oócitos hamster livres zona pelúcida.

Há grande deficiência na literatura sobre os efeitos dos anestésicos dissociativos em animais silvestres. O objetivo do trabalho foi determinar de diferentes protocolos cachorros-do-mato. Foram utilizados cinco machos, clinicamente sadios. Após 12 horas jejum sólido, cada animal submetido a três anestesia dissociativa (quetamina e xilazina – QX, quetamina midazolam QM tiletamina zolazepam TZ) com intervalo 30 dias entre eles. As variáveis avaliadas foram: período latência; hábil anestesia;...
RESUMO As serpentes pertencem ao segundo maior grupo dentro dos répteis, podendo apresentar sazonalidade quanto à espermatogênese, com produção descontínua ou contínua. O presente trabalho tem como objetivo caracterizar aspectos da biologia reprodutiva de Boa constrictor base nos achados histológicos testículos períodos máxima atividade (período gametogênese) e quiescência. Os dois espécimes c. (7767 11752) foram cortados a uma espessura 3μm em micrótomo, corados azul toluidina 1%,...
Abstract: Blood samples collection is a common method in biological research using domestic animals. However, most blood sampling techniques are complicated and highly invasive may therefore not be appropriate for wildlife animals concerning stress. Thus, non-invasive to measure steroid hormones critically needed. The first goal of this study was determine how glucocorticoids concentrations impacted by translocation reproductive activity crab-eating-fox (Cerdocyoun thous) captivity....
