Rastreabilidade de farinha de vísceras de aves por isótopos estáveis em penas de frangos de corte

O objetivo deste trabalho foi detectar a presença de farinha de vísceras de aves (FV) na alimentação de frangos de corte, por meio da análise de penas por isótopos estáveis de carbono (13C/12C) e nitrogênio (15N/14N) e espectrofotometria de massas. Setecentos e vinte pintos machos Cobb foram submetidos aos seguintes tratamentos: ração vegetal (RV) à base de milho e farelo de soja, de 1 a 42 dias de idade; ração com 8% de farinha de vísceras de frango (FV), de 1 a 42 dias de idade; ração vegetal de 1 a 21 dias e ração com FV de 22 a 42 dias; ração vegetal de 1 a 35 dias e ração com FV de 36 a 42 dias; ração com FV de 1 a 21 dias, e ração vegetal de 22 a 42 dias; ração com FV de 1 a 35 dias, e ração vegetal de 36 a 42 dias. Foram colhidas amostras de penas de quatro aves por tratamento aos 7, 14, 21, 28, 35 e 42 dias de idade, que foram submetidas à análise isotópica de carbono (13C/12C) e nitrogênio (15N/14N) por espectrometria de massas. A aplicação da técnica dos isótopos estáveis de C e N a penas de frango de corte, após a utilização de farinha de vísceras na alimentação de frangos de corte, pelo período de até 21 dias, permite detectar a inclusão da FV na dieta.

Extrato de própolis no controle de helmintoses em bezerros

The use of conventional anthelmintic has been a growing concern among consumers who have become more and stricter toward drug residues in products of animal origin. Thus, this research aimed to evaluate the anthelmintic effect of alcoholic extract of propolis, at 30% of concentration, in naturally infected calves. Twelve calves weighting 60 kg and aging 90 days old were used. The treatments were performed by direct oral administration of 10 mL of EAP. The calves received the extract at every 8 h intervals, for five consecutive days. The results were evaluated comprising the detection of light and heavy eggs counted per gram of feces (EPG), immediately before and after treatment, calculating the percentage of reduction. For the statistical analysis, the results were evaluated by Wilcoxon unilateral test of signed points at 5% probability. Trichostrongylus sp. and Strongyloides sp. were found. After treatment, 83% of animals showed an average decrease of 48.48% per counting of EPG. Therefore, propolis may represent an important adjunctive therapy to control helminthiasis in cattle. It was particularly important in ecological organic and biological-dynamic systems of production, whose use of chemicals is prohibitive and limiting factor for certification.

Brucelose suina no Brasil e impacto em Saúde Pública

Proteins of animal origin are among the most consumed foods in the world, this scenario highlights the pig production, providing much of the daily protein intake worldwide. Brazil has significant numbers in the production and export of pork to stand among the first in the world marker. Several diseases such as brucellosis, can configure a threat to this sector. Brucellosis in pigs is an important disease and zoonosis once it is the cause of great economic losses by making the species vulnerable to sanitary barriers as well as putting at risk the health of attendants of farms, slaughterhouses employees and consumers. Pigs slaughtered in slaughterhouses approved by competent organs guarentee the safety of employees, in the flowchart of slaughter, and consumers, but illegal slaughterhouses pose risk to public health

Caracterização histomorfológica de lesões granulomatosas sugestivas de tuberculose ganglionar e pulmonar em bovinos abatidos na região noroeste do estado de SãoPaulo

Tuberculosis infection among humans transmitted by products of animal origin can be caused by Mycobacterium bovis, a concern in developing countries, because the number of human cases is relatively high compared with countries that have implemented programs to eradicate bovine tuberculosis for many years. Because it is a chronic disease with subclinical evolution, it is transmitted to other animals in the herd livestock resulting in high loss losses resulting high (10 to 25%), as well as the zoonotic nature of the disease on public health. This work aimed to study the histomorphology of granulomas in samples of lymph nodes and lungs of animals with suggestive lesions of tuberculosis, as well as those similar to the sanitary inspection. The animals clinically healthy ante-mortem, were slaughtered in a slaughterhouse in the northwestern state of Sao Paulo between April 2008 and April 2009, considering that carcasses had lymph nodes with lesions typical of tuberculosis, exhibiting nodular and hemorrhagic appearance. The caseous or calcified lesions, purulent or not, of various sizes and shapes, were also evaluated. Of the 307,661 animals slaughtered in the mentioned period, 494 gross suggestive lesions of tuberculosis and from 29 cities in the state of Sao Paulo, 16 from Mato Grosso do Sul, Goias 15, one from Mato Grosso and Paraná. Among these, 200 samples (40,5%) were processed for histopathological evaluation by hematoxylin-eosin (HE) and 90 (45%) were subjected to Ziehl-Neelsen (ZN) and examined by light microscopy. In HE staining, histopathological changes of tuberculosis were found in 197 (98,5%), classified according to the stage of development adopted by Wango et al.(31), where 29 samples were included in stage I (14,5%), 53 in stage II (26,5%), 87 in stage III (43,5%), 28 in stage IV (14%). In the ZN staining Mycobacterium sp was found in 89 (99%) of the specimens. The rate of tuberculosis in the herd studied was 0,16%. We conclude that the identification of the disease in slaughterhouses and meat companies from significant gross lesions, enables the implementation of effective measures, specifically the origin of the disease in cattle herds, providing control measures to prevent its spread.
