What are the factors that explain the voluntary adoption of beef cattle traceability at farm level?

The traceability of beef origin is a requirement for some import markets. Research results show that capital-intensive livestock production system, high scale production, access to specialized information and high level of social capital increase the probability of voluntary adoption of beef cattle traceability at farm level.

Study identifies the profile of farms poultry with Megninia spp.

The age range of chicken is a risk factor for the presence of Megninia spp. on commercial poultry farms. In addition, the use of mineral oil and acaricide in the diet for ectoparasite control also seems to be associated with the presence of the parasite. These results are part of a research interested in identifying the profile of farms that have the mite in their sheds. Read More →

Research points to the feasibility of microRNAs as diagnostic biomarkers of heart disease in dogs and cats

Researchers at the Federal University of Paraná, have found through a literature review that microRNAs are effective as diagnostic biomarkers and may be useful in the prognostic evaluation of different heart diseases in dogs and cats. In addition, the alteration in the expression of microRNAs may aid in the understanding of the pathophysiology of diseases not yet fully clarified and may also be a promise in the therapeutic field of veterinary cardiology.

Research tests frequency of elimination of leptospires in urine in cows and sheep

Researchers at the Federal Fluminense University (UFF), in Niterói, Rio de Janeiro, and the Brazilian Agricultural Research Corporation (EMBRAPA), Cattle of Milk, in Valença, Rio de Janeiro, Brazil, have demonstrated through experimentation that leptospiral shedding is intermittent in sheep, regardless of the strain of leptospira inoculated. In cattle, intermittent elimination appeared in less quantity, in only 43.3% of the total animals tested. Read More →

Researchers at the Federal University of Lavras (UFLA), in Lavras, Minas Gerais, Brazil, have demonstrated that the oil extracts of cinnamon, clove and thyme are potential and efficient alternatives in the control of dry bubble disease in mushrooms of the species Agaricus bisporus. Read More →

Fatty acid profile of lamb meat can be changed according to their feeding regime

Researchers at the Universidad Autónoma del Estado de México in Toluca, Mexico, have shown that fatty acid content is higher in lambs fed with pasture compared to animals whose nutrition is supplemented with fishmeal or soybean meal. The study was published in the journal Ciência Rural, vol. 47, no. 4, of April, 2017. Read More →

Research tests the seroconversion of dogs immunized with the Leishmune and Leish Tec vaccines in tests of the Ministry of Health

Researchers at the National Institute of Infectology Evandro Chagas and the Oswaldo Cruz Institute of the Oswaldo Cruz Foundation in Rio de Janeiro demonstrated that in a non-endemic area, dogs vaccinated against canine visceral leishmaniasis (LVC) with vaccines developed in Brazil were not capable of seroconverting in the protocol of tests used by the Ministry of Health.
