Bases ósseas e musculares dos cortes comerciais do tronco de jacaré-do-Pantanal (Caimanyacare Daudin, 1802)

Yacare Caiman meat consumption has become a marketing trend and a commodity on the rise in Mato Grosso state in Brazil. In the last four years, cuts from the trunk represented 28.40% of total meat sales. Although evolutionary studies, morphophysiological ontogenetic and technology research have been carried out, characterization of muscle and bone bases of cuts from the torso has not been previously reported. The aim of this research is to describe the muscles and corresponding bones related to sirloin, filet mignon and meat trims cuts. To describe the bones, we used six boned carcasses from juvenile Yacare Caiman, as well as an adult specimen, obtained by donation after death from the Federal University of Mato Grosso Zoo. The bones were macerated, bleached and their anatomical details recorded. In order to study the muscle, 24 juvenile specimens were obtained after slaughter and skinning and dissected on both sides. The sirloin cut consists of the semispinal, longissimus and iliocostalis muscles, which are inserted on thoracic vertebrae and ribs, as well as lumbar and sacral ribs. The meat trims cut is formed by latissimus dorsi, serratus, pectoral and abdominal (external oblique, internal oblique, transversus and rectus) muscles, based in various bones: bone ribs are the thoracic, lumbar, and sacral ribs, the gastralia, the sternum and epipubis. The filet mignon cut is formed by the internal puboischiofemoralis cranial (sublumbar) muscle and by the troncocaudal (ventral surface of the pelvis) muscle.

Bases ósseas e musculares dos cortes comerciais da cauda de jacaré-do-Pantanal (Caiman yacare Daudin 1802)

The commercial exploitation of the Yacare Caiman (Caiman yacare) has become a relevant commodity in the state of Mato Grosso, Brazil. Crocodilians tail muscles nutritional characteristics and representativeness in body mass became the object of morphophysiological technological and evolutionary studies. The aim of this research was to report, for the first time, the anatomical characterization of muscle and bone bases of Pantanal Caiman meat cuts obtained from the tail. To describe the bones, we used one adult and six juvenile specimens of Pantanal Caiman. In order to study the muscle, 24 juvenile individuals were slaughtered and skinned, preserved in a -20oC freezer and thawed at the time of use, without any fixation. After evisceration, the specimens were dissected on both sides to verify structural symmetry, muscle attachments, sintopy relations, shape and muscular architecture. Caudal vertebrae are procoelous, except for the first of the series, and have sites on the ventral surface of their body where the hemal processes articulate, with the exception of the first and the last four or five vertebrae. The commercial meat cuts of the tail are the tail sirloin, composed of semispinal caudal, longissimus caudal, ilioischiocaudal, long caudofemoral, transverse and deep of the tail muscles, and also the tail tip, consisting of the longissimus caudal and ilioischiocaudal muscles, based on the last five or six caudal vertebrae.

Sistema de grupos sanguíneos AB em felídeos neotropicais e compatibilidade com gatos domésticos

The blood group system recognized for cats is AB. Antibodies against other blood types occur naturally in cats, which makes the compatibility tests and blood typing important for preventing transfusion reactions. Wild felids need blood transfusions in cases of diseases and when run over on highways. The aim of this study was to perform blood typing of eight jaguarundies (Puma yagouaroundi), eight ocelots (Leopardus pardalis), seven pampas cats (Leopardus colocolo), seven domestic cats (Felis catus) of Persian breed and eight non-pedigree domestic cats (Felis catus), and test compatibility among the different species with the same blood types, to evaluate the possibility of performing interspecific blood transfusions. We conducted the study from August to December. We used haemagglutination in test tubes for typing. The occurrence of blood type A was 100% among ocelots, pampas cats and domestic cats of Persian breed, while non-pedigree domestic cats showed 85.72%. The occurrence of type B was 100% for jaguarundis and 14.28% for non-pedigree domestic cats. Regarding blood compatibility tests, 87.5% (n= 4) of the ocelots were incompatible with domestic cats; 100% (n=6) of the pampas cats were compatible with domestic cats, while 100% (n=4) of the jaguarundis were incompatible with type B domestic cats.

Anatomical aspects of the nerves of the leg and foot of the giant anteater (Myrmecophaga tridactyla, Linnaeus, 1758)

Apesar de bem estabelecida nos animais domesticos, a abordagem da distribuicao nervosa distal do joelho e rara em animais selvagens. Portanto, o objetivo deste estudo foi descrever os nervos da perna e pe do Myrmecophaga tridactyla, com enfase na sua ramificacao, distribuicao, topografia e territorio de inervacao. Para tanto, foram utilizados seis cadaveres adultos, fixados e conservados em solucao de formalina a 10%. A dissecacao envolveu desde a formacao dos nervos femoral e isquiatico pelos ramos ventrais dos nervos espinhais lombares e sacrais ate sua distribuicao nos territorios propostos. Os nervos responsaveis pela inervacao da perna e pe do M. tridactyla foram o N. safeno (ramo do N. femoral), os nervos fibular comum e tibial e o N. cutâneo lateral da sura (derivados do N. isquiatico) e o N. cutâneo caudal da sura (ramo do N. tibial). O nervo safeno emite ramos cutâneos para a superficie craniomedial da perna, medial do tarso e metatarso e dorsomedial dos dedos I e II (100% dos casos), III (50% dos casos) e IV (25% dos casos). O nervo cutâneo lateral da sura inerva a regiao cutânea craniolateral do joelho e perna. O nervo fibular inerva os musculos flexores do tarso e extensores dos dedos e a regiao cutânea craniolateral da perna e dorsolateral do pe. O nervo tibial inerva os musculos extensores do tarso e flexores, adutores e abdutores dos dedos e regiao cutânea plantar. O nervo cutâneo caudal da sura inerva a pele da face caudal da perna. Pode-se concluir que os nervos responsaveis pela inervacao da perna e pe foram os mesmos relatados em animais domesticos e selvagens, porem com algumas diferencas, como a divisao mais distal do nervo fibular comum, ausencia de ramos metatarsianos dorsais do N. fibular profundo e uma maior participacao do nervo safeno na inervacao digital, contribuindo com ramos inclusive para os dedos III e IV, alem dos dedos I e II.
