O sistema digestório tem como função fazer a digestão e absorção de nutrientes de modo a fornecer energia para o crescimento e renovação celular. Esse sistema é constituído pelos seguintes segmentos: boca, faringe, esôfago, estômago, intestino delgado, intestino grosso e canal anal. Os cães estão expostos a vários agentes (bactérias, vírus, parasitos e corpos estranhos) que podem acarretar diversos distúrbios gastrointestinais e provocar alterações patológicas no trato gastrointestinal. Diante disso, o objetivo deste trabalho foi identificar as principais patologias encontradas no estômago e intestino de cães por meio do exame de necropsia. Para tanto, foram avaliadas 83 fichas de necropsias preenchidas entre fevereiro de 2014 e abril de 2016, provenientes das aulas práticas de Patologia Animal da Universidade Presidente Antônio Carlos (UNIPAC), de Uberlândia-MG. Durante o estudo, apuraram-se alterações gastrointestinais em 70 casos do total analisado. Ao final do levantamento, constataram-se como alterações mais frequentes: mucosa espessada e hiperêmica, presença de hemorragia, presença de muco e erosões na mucosa.

Bean (Phaseolus vulgaris L.) is one of the most cultivated and consumed legumes worldwide. Brazil is one of the world's largest producers of this crop, which constitutes an important primary source of protein in the diet of its population. In the Northeast region, this legume is a key crop, especially for small family farmers. However, this region has high production susceptibility, which is mainly due to local climatic conditions and the low degree of technification employed. In this sense, the objective of this study was to analyze the productive variations of the bean crop in the municipality of Dois Riachos, Semi-arid of Alagoas, in the period 1998-2015. The production data were obtained from the IBGE Municipal Agricultural Production database, using the Automatic Recovery System (SIDRA), and subjected to correlation analysis and principal component analysis (PCA). The results showed high interannual variability in the production of beans, reflected in the strong oscillation of the analyzed variables. Significant correlations were observed between all variables. The PCA gathered 93.8% of the original data variance in its first two axes, generating 4 clusters that grouped years with similar productive characteristics. The reductions observed for the variables may be linked mainly to abiotic factors, such as the occurrence of prolonged droughts, and the low degree of technification used for this culture.

Ticks are the main ectoparasites responsible for losses in cattle livestock due to spoliation, hematozoa transmission, and destruction of the leather; Rhipicephalus Boophilus microplus is the main agent in tropical countries. The control of these agents is done basically with chemical products, but this procedure has presented some challenges, such as the rapid development of ticks' resistance against them. In this context, the phototherapy is an important alternative for controlling these agents. Schinus terebinthifolius, known as Brazilian peppertree, presents antimicrobial, antifungal, and anti-inflammatory activities. Many organic molecules are reported as having effect on organisms extracted from this plant. This paper aimed to test the efficient activity of the S. terebinthifolius extract under different concentrations on the egg mass formation of R. B. microplus and on larvae hatchability in vitro assay. Engorged females of R. B. microplus were collected in a bovine herd and were taken to laboratory and submitted to immersion test into alcoholic extract at 100%, 50%, 25%, 10%, 5%, and 2.5% dilutions. Test in impregnated papers was carried out under the same concentrations to verify the extract efficacy that causes larval mortality. Control groups were composed, one with water, one with alcohol, and one with a commercial formulation containing cypermethrin, chlorpyrifos, and piperonyl butoxide. It was found that the extract at 70% hydroalcoholic solution showed acceptable efficacy in 50% and 100% dilutions. Result of the impregnated papers test showed 100% extract efficacy at 50% and 100% concentration. These results suggest this phytotherapic extract could be used for R. B. microplus control.

The cattle tick Rhipicephalus Boophilus microplus is responsible for high losses in cattle stocking in tropical area, the losses related to parasitism of this agent represents up to 80% of production losses, represented by spoliation, damage to the leather, hematozoa transmission, among others. The problem of increased of resistance to chemical ectoparasiticids has led to the search for new alternatives, among them there is the herbal medicine, in that it is more accessible, less polluting, suspected delay the resistance phenomenon. In this study, it sought to evaluate the efficacy of alcoholic extract of Gallesia integrifolia (garlic's wood) on tick control R. B. microplus. The test was carried out on engorged ticks and on larvae in impregnated papers in vitro. It was found that the hydroalcoholic extract tested at concentrations of 100, 50, 25, 10, 5, 2.5 and 1% was effective on mortality of adult ticks on 100% concentration from about 5% and on larvae, in 10% concentrations. And at 2.5%, the action on the mortality of larvae was considered satisfactory by the official regulatory criteria. These in vitro results are presented favorable regarding the candidacy of G. integrifolia extract for control of R. B. microplus in cattle.

The parasitism of swine by nematoid Ascaris suum mainly occurs in the early stages of creating the animals, when the parasite makes migration hepato tracheal in those animals and can even cause death of young animals. This nematode is considered the main cause of production loss in swine farms. Given the importance of parasitism by A. suum, it is recommended as ideal conditions identify the agent in the animals the most previously possible. One of the most practical ways to make the diagnosis of this nematode would be the verification of the presence of milky white spots (spot milk) on the surface of swine livers inspected at slaughter resulting from larval migration in that organ. Also, this nematode is the leading cause of condemnation of livers at slaughter inspection. This study aims to assess the level of A. suum infection in pigs at the age of slaughter created in technified farms located in three municipalities in the Zona da Mata region. This study was conducted in three slaughterhouses located in municipality of Piranga and consisting of assess the level of observed alterations in the livers of slaughtered animals. These lesions that were observed showed it as suspicions of parasitism by A. suum in those animals, at least, at some stage of life of these. It should be remembered that some situations as low parasite load, constant cleaning of the stalls and periodic deworming of animals are responsible for many of the animals parasitized by A. suum not reached adulthood or has delayed its development, being present in animals in the larval stage L3 (liver) and L4 and L5 (the lungs). By fact of this agent to be responsible for significant losses in pig farming, it is recommended that these swine farms conduct a strategic protocol of deworming in piglets and matrixes.

This study aims to evaluate the association between the presence of milky spots on the liver of pigs coming from subsistence farms associated with the presence of Ascaris suum adults in the intestinal lumen of these animals. This study was conducted in three slaughterhouses located in the municipality of Piranga, during the process of slaughter of the animals tried to assess the presence of milky spots (spot milk) on the liver parenchyma associated at investigation as to the presence of adults of the nematode in the intestinal lumen of these animals. it was found that in all pigs in which there is the presence of A. suum in the intestinal lumen, it was possible to verify the presence of milky spots in the liver of these animals. However, in the presence of adults in the intestinal lumen occurred in 6.16% of the animals and liver condemnation occurred in 17.12% of the animals, therefore, not every animal with the presence of milky spots in the liver necessarily had had the presence of adults in the intestinal lumen. These animals are raised without any zoosanitary assistance.

The Cerrado biome, predominant in the region of Sete Lagoas is marked by fruit species of the local flora, such as: Araticum, Cagaita, JatobAi, Mangaba, Pequi, among others that are not always known by the community. Environmental education is an important tool for awareness and preservation of the local biome. The extension program aims to bring the community knowledge of the biome and the typical fruit species of the region that are not known and recognized. Inducing a new look and expanding knowledge among students in order to highlight the biome and its characteristics in a playful and didactic way. The program was successful in interventions and achieved satisfactory results in relation to students' perception of classroom work, extolling the biome in which they live, generating new multipliers. The work done in an interdisciplinary way achieved an increase in the percentage of correct answers compared to the numbers obtained before the interventions.

Sheep rearing in Brazil has shown growth in the market. Together with the increase of production of these animals, there is the increase of the damage caused by the presence of gastrointestinal nematodes in these animals and increasing cases of resistance to anthelmintic drugs. This study aimed to evaluate and compare the anthelmintic efficacy of an association between antihelminthic drugs, abamectin and levamisole, and a topical formulation per os of albendazole to the control of gastrointestinal nematodes in sheep. Thus, sheep feces samples were harvested of a property in which the animals were separated into groups and it was proceeded to the treatment of animals, which were divided into three groups, namely C1, control, T1, a association between abamectin levamisole, and T2 and in which there was made the use of albendazole. It was found that only the T1 formulation showed satisfactory efficacy. Still, the groups T1 and T2 showed an average of eggs per gram of feces different C1 group (p

Vampire bats are important agents in the field and currently regarded as the main reservoir in Latin America in the transmission of rabies of herbivores, thus, these animals are monitored by researchers and animal health protection services and suffer from populational control to minimize the impact of the occurrence of cases of rabies in domestic animals. Rabies is a zoonosis of 100% lethality. The presence of haematofagous flies have been observed in these animals. There of is to highlight the importance of these agents that are restricted parasites of bats and could be responsible for transmission of the rabies virus between them. It is also worth emphasizing the importance of assessing the distribution of these parasites of bats according to the climatic conditions of a given site, because these elements are essential to limit the distribution of these parasites. The presence of parasites in animals presents itself as an important element for understanding the mechanisms that are configured in the control of population of a given agent. The present study aimed to record the occurrence of flies in vampire bats in the Forest of Minas Gerais State.
