The dairy cattle production rises worldwide, with genetically selected animals. Consequently, they present high nutritional requirements, especially during the transition period. The aim of this study was to evaluate the effects of parenteral supplementation of a mineral blend composed by selenium, copper, magnesium, phosphorus, and potassium on(More)
The aim of this study was to report the Trypanosoma vivax in goats from a property located in the west of the state of Santa Catarina, Brazil. The identification of the parasite occurred at random, that is, it was displayed a similar morphological trypomastigote form in the blood smear of an animal in the property. Subsequently, in blood samples collected(More)
Infections caused by protozoa often cause diarrhea in newborn calves, leading to high economic losses to dairy farms, diarrhea, often characterized by malabsorption of nutrients, may lead to malnutrition, weight loss, and high mortality rates. Diarrhea is a common clinical sign found in the first days of a calf life in many dairy and beef cattle farms.(More)
Toxoplasma gondii is responsible for reproductive failure in sheep, and it is considered a zoonotic parasite. Therefore, the aim of this study was to evaluate the prevalence of toxoplasmosis and its risk factors at the farm level. For that, 314 sheep from 18 farms of 7 municipalities of the West part of Santa Catarina State, Southern Brazil were used. To(More)
Neospora caninum causes reproductive problems in cattle such as abortion, premature birth, retention of fetal membranes, and metritis. Therefore, this study aimed to verify possible risk factors for N. caninum infection in dairy cattle and their cause-effect relation to neosporosis. Serum samples of 1518 dairy cows from the West of Santa Catarina State,(More)
Leptospirosis is a cosmopolitan infectious disease that causes severe reproductive disorders in cattle, especially those related to abortion. This disease has rodents as main reservoirs; however, cattle are responsible for maintenance of the disease. Thus, the aim of this study was to identify the factors associated with infection and cause-effect relation(More)
Bovine neosporosis is caused by the protozoan Neospora caninum and is one of the major causes of abortion in cows. Cattle are intermediate hosts of this parasite and may have asymptomatic or symptomatic infections. Therefore, the aim of this study was to evaluate oxidative stress marker reactive oxygen species (ROS), thiobarbituric reactive acid substances(More)
The cholinesterases are enzymes involved in severe biological functions in mammals; however, it was not yet study in dairy cows during the transition period. In this period, the animals have high energetic demands for milk production, and the supplementation with mineral can be considered an important approach to fulfill this demand. Thus, the aim of this(More)
Many parasitic diseases are considered asymptomatic, even though some studies have shown that they may cause pathological changes in the host. Therefore, the aim of this study was to evaluate the occurrence of antibodies against Toxoplasma gondii, Neospora spp. and Sarcocystis spp. in horses, and to identify the risk factors for disease. For this, 174(More)
The aim of this study was to evaluate seric NTPDase and 5'nucleotidase activities of cattle naturally infected by Eurytrema coelomanticum, as well as to correlate them to histopathological lesions in the pancreas and the degree of parasitism. Blood samples and pancreas of 51 bovines were collected on a slaughterhouse in Southern Brazil: 33 from cattle(More)
