RESUMO

Agoutis (Dasyprocta prymnolopha, WAGLER 1831) have been studied in captivity as a potential source of meat for rural populations in Brazil, as a way of providing low-cost protein and easing hunting pressures in local communities. However, little is known about their physiological blood markers, which are crucial for animal husbandry and effective welfare management. This study provides hemogasometric and ionic venous parameters for female agoutis raised in captivity in the drylands of Brazil. Venous blood samples were collected from six females and analyzed for dissolved gases and ions in the blood. Hemogasometric parameters, especially base excess and anion gap were generally heterogenous, while ions varied little among individuals. Moreover, we observed high chlorine values and negative base excess values, which suggest that some animals might be implementing compensatory mechanisms for ion imbalances. We provide a preliminary note on agouti venous gases and ions, while reiterating the importance of the clinical context and in-house parameter definition to maximize accuracy.

RESUMO

Background: The common marmoset (Callithrix jacchus) belongs to the family Cebidae and Subfamily Callitrichinae, a group formed by the smallest anthropoid primates. It is a very common species and adapts easily to captivity, an aspect that encourages the clandestine capture of these animals and makes them susceptible to wounds resulting from clandestine rearing and inadequate management, so that studies to understand the species are extremely important.  With the objective of supplying anatomic bases for the practice of epidural anesthetic, data were studied regarding the topography of the common marmoset (Callithrix jacchus).Materials, Methods & Results: The study was carried out at the Laboratory of Veterinary Anatomy at the Federal University of Campina Grande (UFCG), PA, Brazil. Ten adult common marmosets (Callithrix jacchus) were used, 5 males and 5 females, with different causes of death. A round workbench magnifying lamp was used to better visualize the dissecation field.  Number 15 scalpel blades, surgical pincers and scissors were used to dissect.  After fixing in 10% formaldehyde aqueous solution, dissecation was made along the mid dorsal line, from the cranial thoracic region to the tail base to expose the vertebral arches and measure the intervertebral spaces.  The vertebral arches were removed, and consequently the spinal dura mater was exposed, that was sectio

RESUMO

The determination of the puberty beginning is widely studied in domestic animals and rodents. However, there are scarce researches with the purpose to establish parameters for the reproductive biology in Agoutis. Thirty-one male Agoutis, Dasyprocta agouti species had been used, originated from the Universidade Federal do Piauí - PI, and from the Mossoró Superior Scholl of Agriculture - RN. Immediately after the orchiectomy, histological sections were made, the tissues were stained with hematoxylin-eosine and analyzed for the following parameters: aspects of the seminiferous tubule lumen; presence of primary spermatocytes; presence of spermatid cells and formation of the first stages of the seminiferous epithelium cycle (SEC), in accordance with the tubular morphology method. The period from the birth up to five months of age corresponded to the impuberal phase; from six to eight months, to the transition from the prepuberal phase to puberty; from nine to ten months, to the puberty; and, from twelve to fourteen months of age to the after-puberty phase. The puberty of the Agouti (Dasyprocta aguti), occurred since seven months of age, being the establishment puberty beginning evidenced at nine months of age.

A determinação do estabelecimento da puberdade é bastante estudada em animais domésticos e roedores, no entanto, são escassas as pesquisas com a finalidade de estabelecer parâmetros para a biologia reprodutiva em cutias. Foram utilizadas 31 cutias machos da espécie Dasyprocta agouti, oriundas da Universidade Federal do Piauí, Estado do Piauí, e da Escola Superior de Agricultura de Mossoró, Estado do Rio Grande do Norte. Imediatamente após a orquiectomia foram retirados fragmentos e estes foram processados histologicamente, os tecidos foram corados com hematoxilina-eosina e analisou-se os parâmetros seguintes: aspectos de luminação dos túbulos seminíferos; presença de espermatócitos primários; presença de espermátides e formação dos primeiros estágios do ciclo do epitélio seminífero (CES) segundo o método da morfologia tubular. O período desde o nascimento até os cinco meses de idade correspondeu à fase impúbere; dos seis aos oito meses de idade a fase de transição da pré-puberdade à puberdade; dos nove aos dez meses de idade à fase da puberdade; e dos doze aos quartoze meses de idade à fase da pós-puberdade. A puberdade da cutia (Dasyprocta aguti), ocorreu em animais a partir dos sete meses de idade, e o estabelecimento da puberdade foi constatado em todos os animais estudados aos nove meses de idade.

RESUMO

The study of portal vein concerning the confluent vessels to its formation and its tributaries was carried out in adult agouties (3 females and 7 males), the venous system of which was infected with colored latex and fixed in 10% formol. After dissection, it was noted that the trunk of the portal vein has its origin in the confluence of two roots, represented in 90% of the cases, by the lienal vein and by the common mesenteric trunk, composed by cranial and caudal mesenteric veins and, in 10%, by lienal vein and by cranial mesenteric vein. The trunk of the portal vein has as its tributaries the cranial pancreaticoduodenal vein (100%), the right gastric vein (90%), and the right gastroepiploic vein (40%).

O estudo da veia porta quanto aos vasos confluentes para sua formação e suas tributárias foi efetuado em 10 cutias (Dasyprocta aguti), adultas (3 fêmeas e 7 machos), nas quais o sistema desta veia foi injetado com látex corado, sendo a seguir fixadas em formol a 10% e dissecadas. Verificou-se que o tronco da veia porta origina-se sempre pela confluência de duas raízes, sendo representadas em 90% dos casos, pela veia lienal e pelo tronco mesentérico comum, constituído pelas veias mesentéricas cranial e caudal e, em 10%, pela veia lienal e pela veia mesentérica cranial. O tronco da veia porta recebe como tributárias a veia pancreaticoduodenal cranial (100%), a veia gástrica direita (90%) e, ainda, a veia gastroepiplóica direita (40%).
