Outbreak of Trypanosoma vivax in Dairy Cows: Hematologic, Immunological and Antioxidant Responses Before and After Treatment with Isometamidium Chloride

Pathogens (2025)

Alexandro Fritzen Maksuel Gatto de Vitt Guilherme Luiz Deolindo M. Signor Norberto Correa

Trypanosoma vivax infection is an emerging condition that causes damage and mortality among cattle and is transmitted by mechanical vectors or contaminated fomites. This disease has been spreading in southern Brazil, causing anemia, weight loss, diarrhea, abortion, and infertility; however, its behavior and host–parasite relationships are not yet fully understood. To clarify this issue, animals that presented clinical signs were subjected to an immunochromatographic screening test. An indirect immunofluorescence test was then performed on samples collected before treatment (the gold standard test), which showed that in the herd of 20 cows, we had 14 seropositive for T. vivax. Blood samples were collected before and after treatment to study the effects of the disease and treatment, with the cows divided into two groups: infected and uninfected. Cows were evaluated for hematologic, biochemical, and antioxidant responses, comparing them with uninfected and infected animals, as well as pre- and post-treatment (isometamidium chloride—1 mg/kg body weight [BW]). There was no difference (p > 0.05) between groups in milk production and feed intake; however, ten days after treatment, there was an increase of 1.72 kg of milk in cows diagnosed as infected with T. vivax. Seropositive cows had lower erythrocyte counts, hemoglobin concentrations, hematocrit, platelet counts, and lymphocyte and granulocyte counts. In seropositive cows, the higher total protein concentration is due to increased globulins, which the protein profile by electrophoresis showed to be related to higher levels of immunoglobulins (IgA and other heavy-chain immunoglobulins), ceruloplasmin, haptoglobin, ferritin, C-reactive protein; associated with lower transferrin levels. The activity of the enzymes aspartate aminotransferase, gamma-glutamyl transferase, cholinesterases, and creatine kinase were compared in seronegative and seropositive cows for T. vivax. Lower serum calcium levels were observed in seropositive cows. Cows diagnosed with trypanosomosis presented high levels of reactive oxygen species, lipid peroxidation, protein oxidation, nitrite/nitrate activity, superoxide dismutase, and glutathione peroxidase. The enzymes catalase and glutathione S-transferase presented lower activity in the blood of seropositive cows compared to the control on the day of diagnosis, which was no longer observed ten days after treatment. The animals exhibited hypogalactia, anemia, thrombocytopenia, leukopenia, and acute phase response accompanied by liver and muscle tissue damage and oxidative stress, demonstrating the effect of T. vivax infection in naturally infected Jersey cows.

Combination of Essential Oils and Extracts Enriched with Tocopherols in Diet of Holstein Steers and Its Effect on Ruminal Fermentation, Antioxidant and Anti-Inflammatory Response, Feed Efficiency and Fatty Acid Profile in Meat

Fermentation (2024)

João Gustavo Weschenfelder Wandscheer Natalia Turcatto Guilherme Luiz Deolindo M. Signor Alexandro Fritzen

Background: This experiment evaluated whether the combination of essential oils (thyme, rosemary, orange) with extracts of Cinnamomum and Quillaja saponaria (enriched with tocopherols) in steers’ diet has positive effects on the health, digestibility, growth, oxidative stress, and fatty acid profile of meat. Methods: The experiment included 24 Holstein steers, divided into two groups, randomly divided (treated = phytogenic mixture (n = 12); control = monensin (n = 12)), undergoing a growth phase of 120 days and 90 days of finishing in individual pens, with a monthly collection of blood, rumen fluid, feces, and feed. Results: In the finishing phase (days 150 to 210), there was a tendency (p = 0.07) toward more significant average daily weight gain when cattle consumed a phytogenic mixture than monensin. The use of the phytogenic product showed greater feed efficiency in the period from 150 to 240 days (p < 0.05), with higher levels of short-chain fatty acids (SCFAs), without differences in the composition of these SCFAs between the control and treated groups, with a reduction in apparent digestibility in the treated group. In blood parameters, the treated group showed higher erythrocyte counts (p < 0.05) without changes in leukocytes, lymphocytes, granulocytes, monocytes, and platelets. The phytogenic treatment demonstrated higher total protein and globulin levels, with increased glucose levels on days 30 and 210 (p < 0.05). Ceruloplasmin and haptoglobin levels increased in the treated group without changes in ferritin, transferrin, C-reactive protein, IgA, and heavy-chain immunoglobulins (p < 0.05). A reduction in oxidative stress was observed using the phytogenic agent, with a marked decrease in the levels of reactive oxygen species (ROS) and carbonyl proteins, with a tendency to increase glutathione S-transferase (p < 0.05). In meat, the phytogenic reduced saturated fatty acids with increased polyunsaturated fatty acids and increased the omega 6/omega 3 ratio. Lower levels of thiobarbituric acid reactive substances and ROS were detected in the meat combined with a higher concentration of total thiols in the treated group than in the control group. Conclusions: The use of the phytogenic in steers’ diets has shown to be a viable candidate for replacing monensin, presenting equal or superior performance results with systemic modulating effects on oxidative stress, meat quality, and serum and biochemical parameters that contribute to more substantial health and efficiency.

Intake of Condensed Tannins (Acacia mearnsii) by Lambs in Confinement and Its Impact on Growth Performance, Rumen Environment, and Meat

Fermentation (2024)

Andrei Lucas Rebelatto Brunetto Ana Cristina Agulheiro‐Santos Isadora Zago Guilherme Luiz Deolindo Luísa Czamanski Nora

This study determined whether adding condensed tannins to the diet of confined lamb improves performance, metabolism, health, and meat composition and quality. We used 24 Lacaune lambs with an average initial weight of 24.5 ± 0.24 kg. The animals were divided into 12 pens with two animals each. In the treatment group, a black wattle extract was added to the lamb concentrate (2.5 g/kg dry matter), while the control group received only the basal diet (without extract). Black wattle contained 98.6 g/kg of condensed tannin. There was no difference between the performance variables, which included weight gain, feed intake, and feed efficiency. However, the group fed on condensed tannins showed higher carcass yield and a higher percentage of linked intramuscular fat. In meat, a lower proportion of saturated fatty acids combined with higher concentrations of unsaturated fatty acids was observed in lambs of the condensed tannin group. The polyunsaturated fatty acids (PUFA) were no different; however, a higher PUFA/SFA ratio was observed in animals with condensed tannin intake, and a higher proportion of ω6 and ω3 was observed in the meat of these animals. The meat’s protein and ash content did not differ between treatments, as did the meat’s water retention capacity, color, and luminosity. Furthermore, animals that fed on condensed tannins had lower cholesterol levels and higher globulin content. The values of erythrogram variables were lower in lambs that consumed condensed tannins. More significant ruminal bacterial activity was also observed in the group receiving condensed tannins. The antioxidant effect was verified with lower thiobarbituric acid reactive species (TBARS) levels and more significant antioxidant enzyme activity. We conclude that adding condensed tannins improves carcass yield and increases the percentage of fat in the carcass, improving the fatty acid profile, which may be linked to the antioxidant effect, in addition to the health benefits of the consumer of this product.

Análise físico-química de méis florais produzidos por Apis mellifera L. entre 2018 e 2020 no Estado de Santa Catarina, sul do Brasil

Revista de Ciências Agroveterinárias (2024)

Aline Nunes Giovanna Balen de Azambuja Guilherme Luiz Deolindo Cleiciane Rita Gadiel Zilto Azevedo

O Brasil é um grande produtor de mel e é reconhecido internacionalmente pela qualidade deste produto. Para avaliar a qualidade do produto foram realizadas análises físico-químicas. Nesse sentido, amostras de mel das onze zonas agroecológicas de Santa Catarina, sul do Brasil, foram analisadas quanto ao teor de umidade, pH, açúcares redutores, sacarose aparente, atividade de água, enzima diastase, cor e reação de Lund. Foram analisadas 65 amostras de mel coletadas na safra 2018-2019 e 50 na safra 2019-2020. Os dados foram submetidos à análise de variância e ao teste de Scott & Knott (p<0,05) com auxílio de scripts implementados em linguagem R. A análise de componentes principais (ACP) também foi aplicada ao conjunto de dados fisico-químicos para verificar possíveis agrupamentos de amostras entre as zonas agroecológicas do estado de SC e interações entre as variáveis. Os valores de umidade e a sacarose aparente apresentaram as maiores discrepâncias em relação ao permitido pela legislação brasileira. Três zonas agroecológicas foram correlacionadas em termos dos dados encontrados. A ACP mostrou serem a umidade, pH e atividade de água parâmetros relevantes ao agrupamento e discriminação das amostras de méis. A partir dos resultados observados, percebe-se a necessidade de monitoramento contínuo da qualidade daquele alimento, bem como a capacitação dos apicultores para colheita, processamento e armazenamento.

Abstract This study aimed to determine the effects of aqueous extract of red propolis (RP) as an alternative to synthetic antimicrobial for quails enhanced egg quality and maintained health status. A total of 120 laying quails with 52 days of age were were randomly allotted to dietary treatments and six replicates of five birds each in completely randomized design. There were four dietary treatments as following: Control (TC), with enramycin (TE), 1g RP/kg of feed (RP1), 2g RP/kg of feed (RP2) in concetrated diet raised for 63 days. The results of productive performance such as percentage of egg production, feed intake per quail per day, average egg weight, egg mass, foods conversions showed no significant difference between treatments. The quails fed with red propolis in fresh eggs showed darker yolk (P < 0.05), with higher intensity of red and lower intensity of yellow; as less than 6.0 pH yolk; microbiological characteristics analyzed on the surface of eggs and feces of quails was lower and less than compared with other treatments. It is possible to conclude that red propolis showed promising results to be used as a feed additive for laying quails, since it maintained the productive performance of these animals and caused qualitative improvements in the physicochemical and microbiological characteristics of the eggs.

The objective of this study was to evaluate whether the addition of a blend based on α-monolaurin mono-, di- and triglycerides of butyric acid, and lysolecithin on the performance even on diets containing reduced inclusion of oil in the diet and without the use of growth-promoting antibiotics of broilers considering the effect on health, performance, and meat. Three treatments were defined: positive control (TP: with enramycin), negative control (TN: no enramycin), and blend (T-FRA: with monolaurin and glycerides of acid butyric minus 0.8% soybean oil). At 21 days, broilers treated with TP and T-FRA obtained the lower feed conversion ratio (FC); at 35 days, T-FRA broilers obtained lower FC than TN broilers. Cholesterol levels were higher in the blood of T-FRA broilers. On day 42, levels of ROS and TBARS were lower in the intestine, muscles, and liver of T-FRA broilers. Moreover, glutathione S-transferase and total non-enzymatic antioxidants were greater at the intestinal and muscular levels. The T-FRA broilers had a lower percentage of lipids in the meat. The MIC indicated that 111mg of the blend/mL inhibited the growth of E. coli; however, the counts of total coliforms and E. coli in the feces and the broilers' litter did not differ between treatments. In conclusion, the addition of the blend T-FRA in broiler diets was able to improve the feed conversion and maintain the other performance parameters even considering a reduction of 0.8% in the inclusion of oil.
