The giant anteater (Myrmecophaga tridactyla) is a member of the Myrmecophagidae family and now classified as "Vulnerable" due to risk extinction. In spite this, research on reproductive biotechnologies in species rare, semen collection has only been performed using electroejaculation date. Pharmaceutical through urethral catheterization become distinct method that being applied numerous wild animals. addition establishing species-specific setup, we compared acquired by three animals obtained...
Cryptorchidism is a genital alteration wherein one or both testicles fail to descend into the scrotum and has multifactorial causes. A free-range adult male was captured twice in Pantanal of Nhecolândia put GPS collar semen collection. Pharmacological collection, andrological examination analysis were performed. At first capture during only left testis found, qualified as cryptorchid. The penis had no penile spines at either procedure. volume obtained second 435 160 μL, respectively, with...
Abstract The study of free‐living felids requires the capture individuals from wild to collect biological samples and equip them with GPS‐satellite collars for telemetry monitoring. traditional methods used by researchers are box traps trained hounds, both which have disadvantages. We present description foot snare adaptations required jaguars cougars, showing its efficiency. consists a combination structures. It is composed thrower system, responsible closing steel cable noose on paw...
Among the different methods used for semen collection from domestic cats, pharmacological by urethral catheterization becomes disruptive. Medetomidine is elected α2-adrenoceptor agonist that, but in several countries, it not commercially available. This study aimed to evaluate efficacy of detomidine compared medetomidine collecting cats. Urethral was performed on 13 mongrel cats using a disposable semi-rigid tomcat urinary catheter. Of 19 collections with induction, 94.7% were successful,...
The crab-eating fox inhabits all Brazilian biomes, but little is known about its in situ reproduction. objective of this study was to assess the pharmacological semen collection by urethral catheterization foxes. In addition, we compare seminal and reproductive biometric parameters between juveniles adults, as well breeding season (June September) non-breeding (October May). For study, free-living foxes (individuals n = 8; adult 6 juvenile 2; capture events N 10) were captured Pantanal using...
The aim of this study was to develop a field-friendly method for free-living jaguar and cougar semen cryopreservation. Six captive Jaguars Panthera onca three Cougars Puma concolor were chemically restrained with combination medetomidine (0.08–0.1 mg/kg) ketamine (5 mg/kg). Semen collected through tomcat urinary catheter an open end, diluted final concentration 50 x 106 sperm/mL in TRIS-egg yolk extender packaged into 0.25 mL straws. We compared two cooling methods: CoolA - which straws...
The in situ population of jaguars the Caatinga is less than 250 individuals, subdivided into five subpopulations, and classified as endangered regarding its risk extinction. Luisa, a 15-year-old female weighing 36 kg, was last known ex jaguar from this biome. Her reproductive evaluation detailed manuscript. Luisa subjected to both clinical laparoscopic her system. After 45 days investigation, she died unexpectedly, skin fragments were taken establish postmortem fibroblast lineage. At...
The parasite Calodium hepaticum is a zoonotic, cosmopolitan nematode often associated with rodents. These nematodes have low host specificity and zoonotic potential, affecting the liver of their hosts. objective this work to describe first case, as far authors are aware, C. causing granulomatous hepatitis in captive Mandrillus sphinx. A necroscopic examination was performed organs were removed evaluated; then, 1 cm³ fragments collected preserved 10% buffered formalin. After fixation, samples...
RESUMO Este estudo objetivou descrever o aspecto hematológico de seis onças-pardas (Puma concolor) infectadas pelo Cytauxzoon felis. Os casos infecção foram identificados durante manejo sanitário 11 animais um centro reabilitação silvestres. Estruturas compatíveis com piroplasmídeos observadas a avaliação do esfregaço sanguíneo e confirmadas como felis pela técnica PCR. A análise estatística demonstrou diferença significativa (P<0,05) no número absoluto dos linfócitos entre os grupos...
ABSTRACT We evaluated the effect of reducing free calcium in cryopreservation medium, using chelator ethylene diamine tetracetic acid (EDTA) at 0.3% and 0.5% concentrations. Three male mixed breed dogs were subjected to semen collection by digital manipulation (n=16). Each ejaculate was divided three aliquots, each one diluted TRIS-glucose-egg yolk extender with 6% glycerol Equex STM Paste® (TGE, control); added EDTA (EDTA 0.3) or 0.5). Calcium concentration reduced 0.3 all ions chelated...
