Purpose: the purpose of this review is to address issues related to the teaching of Animal Welfare (bea), focusing on the Brazilian case, and discuss the challenges and possibilities for improvement. Description: it is essential that students of animal science courses in the undergraduate program learn the conceptual foundations and main applications of bea. Point of view: while bea teaching in Brazilian universities has had a marked growth in recent years and has allowed to identify some of its national characteristics, it in turn benefits significantly from the association with research as this is an area of knowledge under construction. Conclusions: the main challenges posed in terms of bea teaching in Brazil are discussed. By introducing bea teaching into their curricula, universities increase its graduates’ suitability for current labor market and contribute to progress in the ethics of human-animal relationship.

Introduction: in cattle, the oviduct is essential in the process of maturation, fertilization and acquisition of competence for proper development of an embryo until the blastocyst stage. Once the cells in the internal lining of the oviduct provide substances that positively affect sperm as it crosses the female genital tract, the surface components are modified or removed by secretions present therein. Such modifications may include cholesterol depletion on sperm surface, altered glycosaminoglycans, and change in ions. Methodology: the objective was to evaluate the influence of adding cell culture medium of bovine oviduct cells on sperm parameters such as motility, vigor, and integrity of cytoplasmic membrane. The sperm cells were incubated with 164 μl of Talp-sp-Uso in the control group (TCt); 161.5μl of Talp-sp-Uso, in addition to 2.5μl of heparin (20μg/ml) in treatment 1 (THep) and 128μl of Talp-sp-Uso, along with 36μl of culture medium with secretions of bovine oviduct cells in treatment 2(TOv). Tests were performed at zero time (to show that the medium of treatments did not hurt the sperm cells) and after three hours of incubation. Results: no significant differences in progressive motility, vigor and integrity of cell membrane between treatments were found. However, sperm cells cultured with oviduct cell secretions showed a greater percentage of total motility after three hours of culturing, in contrast to sperm cultured in the presence of heparin. Conclusion: oviduct cell secretions do not affect progressive motility, vigor or integrity of the cytoplasmic membrane of sperm cells; however, they prolong sperm motility.

Purpose: this article aims to report the findings of a clinical case of hypertrophic osteopathy. Topic: hypertrophic osteopathy is a rare paraneoplastic disorder associated with painful overgrowth of the periosteum of long bones, usually triggered by primary or metastatic lung tumors. Development: the case of a 12-year-old Rottweiler with hypertrophic osteopathy associated with pulmonary metastases from breast carcinoma is presented. Conclusions: clinical and radiographic findings and therapeutic possibilities are discussed.

Topic and scope: this article aims to provide the reader with an overview on toxoplasmosis, a zoonosis caused by Toxoplasma gondii, which affects both intermediate and definitive hosts. We seek to understand the dynamics of the disease, putting aside certain myths on the subject. Characteristics: felines ( Felidae) are the definitive hosts, among which are the cats as the closest animal to the human species that develop the gendered form of the parasite and release the infectious oocysts in the environment; hence their presence is essential to the life cycle of T. gondii. Findings: research on cats worldwide are limited since sampling is highly complex; however, there is a wide variety of studies on their taxonomy, morphology, life cycle and molecular biology, as well as epidemiological distribution, hosts, transmission routes, sources of contamination, and risk factors associated with the infection in this and other vulnerable species. Conclusions: the knowledge of this parasite infection is of great importance, especially in cases of pregnant women and immunosuppressed individuals, who can manifest complications of the disease.

Introduction: currently, there are new diagnostic tools and therapies for heart disease, but with no serious scientific consensus on the questions about the normal structure and function of the heart. Helical ventricular myocardial band of Torrent-Guasp is the revolutionary new concept in understanding global, three-dimensional, functional architecture of the ventricular myocardium. This concept defines the architecture and net forces developed within the ventricular mass. Materials and methods: 36 hearts of dogs of various weights, breeds and sexes were used to demonstrate the existence of a ventricular myocardial band in the canine myocardium by manual dissection. Results: the dissection performed showed a strong trend towards a continuous helical structure with a longitudinal arrangement of ventricular myocardial fibers, forming a single functional muscular band that begins at the height of the pulmonary artery and ends at the level of the aorta. Different segments of the band were identified: right (presence percentage 100 %) and left (100 %) with respect to parts of the basal loop, and descendant (100 %) and ascendant (100 %) in the dissection of the apical loop. Conclusions: the presence of the ventricular myocardial band in the canine myocardium (Canis lupus familiaris) was demonstrated and their structures identified. This is a new concept in the anatomy of the canine ventricular myocardium, where the complex network of the double helicoid is macroscopically evidenced. According to the theory of Torrent-Guasp, the canine myocardium would have the following contraction sequence: contraction of the basal loop, contraction of the descendant and ascendant segments of the apical loops, and ventricular ejection and suction.

Introduction: There are few studies and research regarding the external and internal characterization of porcine kidney unlike other species. The purpose of this study was to establish the similarities for each type of anatomical pattern in the internal and external structures of the kidney and the renal secretion system of the species. Materials and Methods: The variables were analyzed from 60 renal blocks by injecting these with polyester resin, from animals destined for human consumption ethically obtained from the beneficiation plant Vijagual city of Bucaramanga. Result: External Morphometry for both kidneys, have a length of 120mm, the width of 27.3 mm. The renal arteries showed 3 different branching patterns (pattern I: 96.7%; pattern II: 1.7%; Pattern III: 1.6%). A third subpattern (Ic) in group I was found in 9.4% of samples. The distribution of the tributary veins present pattern type I (81%) and the pattern II (20%). Pattern III was not demonstrated in any of the examined samples. The caliber of the ureters averaged 6.9mm; the width of the renal pelvis was 12.2mm. The distribution patterns of the chalices were divided into two groups (A: 30% B 70%). Each pattern presented a subdivision in AI, AII, BI, and BII. Conclusions: The distribution patterns of renal structures found in this study are similar to those reported in previous studies, besides the contribution of an arterial pattern (Ic) was evidenced by this research.

Introduction: in formulating concentrates for broilers (fe), inorganic sources of phosphorus (P) are used. Phytic P (derived from vegetables in concentrates) and excess added inorganic P are eliminated in the stool and cause problems to the environment. The aim of this study was to evaluate the reduction of the demand for available phosphorus (Pd) in 8-to-21-day-old male fe subject to three levels of Pd with phytase (500 FTU kg -1 of concentrate) on performance and bone parameters. Materials and methods: 480 Cobb® fe were used and distributed according to a completely randomized design. Pd levels were 0.391% (level of demand for male fe with medium performance) plus two levels: -10 % and +10%. The ratio between calcium and Pd was 2.13:1 (Ca:Pd). 8 replications of 20 birds per box were performed and an iso-nutrient diet was provided. Final weight, weight gain, concentrate intake, feed conversion, and ash, P and Ca contents in tibias were evaluated. Collected data were submitted to anova ; where there was a significant difference (P< 0.05), the treatment averages were compared by the snk test. Results:concentrate intake decreased (P=0.0265) at the level of 110%. As for bone mineralization, the 90% level resulted in lower ash (%), calcium (% e g) and P (% e g; P<0.05) contents. Conclusion: it is possible to decrease the demand for Pd in malefe when their performance has been evaluated. Also, diets containing 10% less than the demand for Pd in malefe meet the needs for animal bone mineralization.
