Background: The blowfly (Diptera: Calliphoridae) causes traumatic myiasis in farm animals, with deeply embedded larvae that lead to serious tissue damage and sometimes death. Treating this form of myiasis is difficult, often resulting in poor outcomes. As a homeopathic preparation that can mimic traumatic myiasis symptoms, could potentially supplement treatment.

Background: Myiasis by (Diptera: Calliphoridae) is a serious problem in animal health. Homeopathic presents similarity with the clinical presentation verified in these cases and has already shown efficacy on the blowfly that causes this pathology. This article presents the report of a series of clinical cases of myiasis by in sheep that underwent adjuvant treatment with homeopathic and presents a theoretical-scientific discussion of biological events related to the clinical treatment of the condition.

Stabled horses often experience negative emotions due to the inappropriate living conditions imposed by humans. However, identifying what emotions horses experience and what can trigger positive and negative emotions in stabled horses can be challenging. In this article we present a brief history of the study of emotions and models that explain emotions from a scientific point of view and the physiological bases and functions of emotions.

This study aimed at evaluating parasitological and blood variables in native breed Crioula Lanada sheep belonging to the same herd, to identify and compare susceptible or resistant individuals to gastrointestinal nematodes during gestation and lactation phases. For this purpose, 18 Crioula sheep were used within 2 years of evaluation, in which blood and feces samples and weight of the animals were taken from their 4th month of gestation until the weaning of their lambs, in the 4th month postpartum. Feces samples were used for counting eggs per gram of feces (EPG) and, thus, to identify 12 resistant ewes (EPG < 1,000) and 6 susceptible (EPG > 1,000) to gastrointestinal nematodes.

In this study, we aimed to introduce a new technique called TF-Test Modified∕Dog for the diagnosis of gastrointestinal parasites in dogs. Fecal samples from 106 dogs were processed by the technique TF-Test Modified∕Dog and the techniques of centrifugation-flotation in zinc sulfate, simple-flotation by saturated solution of sodium chloride, direct microscopy exam and TF-Test Conventional. Sensitivity was higher in the TF-Test Modified∕Dog (98.

The objective of this study was to investigate reproductive characteristics of stallions at a tropical zone in the breeding and non-breeding seasons. The following parameters were assessed: testicular volume; semen quality; and serum concentrations of LH, FSH, and testosterone; in addition to the percentages of germ cells and proportions of germ cells/Sertoli cells by testicular cytology in stallions. Semen was collected from eight adult stallions twice a week during a 12-week period in both seasons (6 weeks before and 6 weeks after the summer and winter solstices).
