“…Serum diagnosis to BVDV and BoHV-1 was performed by virus neutralization (VN) according to OIE (2004). Antibodies against BRSV were also detected by virus neutralization, but according to Affonso (2012). Serological response was evaluated in relation to BVDV-Ia NADL strain, BoHV-1 Los Angeles strain and ATCC VR-1485 incubated in Madin-Darby Bovine Kidney cells (MDBK) in 96 well plates.…”

Bovine respiratory disease (BRD) is responsible for economic losses in cattle production. Viruses are categorized as primary etiological agents. The aims of this study were to evaluate the presence of antibodies against bovine viral diarrhea virus (BVDV), bovine herpes virus type 1 (BoHV-1), and bovine respiratory syncytial virus (BRSV) in healthy and BRD calves from family farming in relation to clinical signs of BRD. Hundred and forty-five calves were randomly selected and physical examination was performed. Only 123 animals were classified as healthy and BRD calves. Antibodies were evaluated by virus neutralization test. Person’s Chi-square test and Fisher’s exact test were performed as univariate analysis. Binary Logistic Regression was applied as multivariate analysis. Variables with P<0.10 were considered statistically significant. Variables with 0.15<P<0.10 were considered as statistical tendencies. Antibodies against BoHV-1, BVDV, and BRSV were detected in 32%, 23% and 37% animals. Antibodies against both three viruses were detected in 26.8% of calves. The presence of antibodies against BRSV were associated to normal heart rates (P=0.018) and unilateral airflow (P=0.035). Tendency was observed to unilateral airflow (P=0.06) Statistical tendencies were observed to Ab-BoHV-1 and body temperature (P=0.119) and breathing pattern (P=0.123). The profile of antibodies against respiratory viruses in calves from Brazilian family farming was firstly described. The results confirmed the importance of some clinical signs to viral infection.

“…A presença de P. multocida foi associada a tosse nos animais examinados enquanto a sua ausência foi associada a secreção nasal mucopurulenta e mucosa, som submaciço, crepitação fina, estertor úmido (Tabela 6). Houve uma chance maior de 5,5 vezes de apresentar tosse na presença de P. multocida enquanto na sua ausência hà uma maior chance dos animais apresentarem secreção mucosa (7,3) e mucopurulento (5,8), som submaciço (9,6), crepitação fina (13) e estertor úmido (5).

Propolis is a resinous substance from a mixture of different plant parts and molecules bees compose. This narrative review article explored the application of propolis in large and small animal practices in PubMed, Scopus, and Google Scholar databases. Propolis is applied in different pharmaceutical forms. Due to its numerous biological actions, such as antimicrobial, anti-inflammatory, antioxidant, antiparasitic, antiulcer, antitumor, and immunomodulatory, propolis can improve animal health and production. Propolis could be used as an alternative treatment for many diseases, such as mastitis, lumpy skin disease, foot and mouth disease, reproductive disorders, and diarrhea in cattle. Moreover, it could improve weight gain in cattle. In equine, propolis has been used as a local anesthetic and for treating dermatomycosis, chronic bronchitis, and skin wounds. In pigs, propolis has been used to treat enzootic pneumonia and as a prophylaxis for gastrointestinal and respiratory diseases in weak pigs. Propolis has been applied to treat caseous lymphadenitis and parasitic diseases in sheep and goats. Furthermore, it improves the immune status of kids and the health status of late pregnant ewes. In dogs and cats, propolis has been applied to treat otitis externa, eye diseases, Cushing’s syndrome, and dermatophytosis. In dogs, propolis can treat transmissible venereal tumors. Moreover, propolis positively affects animal production, average daily gain and milk yield in sheep, growth of calves, lambs, and piglets, and cow’s milk nutritional quality. On the other hand, the addition of propolis to the diet of feedlot bulls and pigs has no effect on their feed intake, hematological, biochemical, and immunological parameters, nutrient digestibility, microbial synthesis, and carcass characteristics. Based on the available clinical studies, propolis has potential benefits for animal health in cattle, equine, sheep, goats, pigs, dogs, and cats. According to the available literature, propolis is a natural promising agent that can alternate conventional pharmaceuticals, particularly antibiotics. It improves animal health and production with no adverse effects and low cost. Most conducted studies on the efficacy of propolis on animal health and production are in vitro. Due to its scarcity, further controlled clinical trials are recommended to evaluate the exact usefulness of propolis in veterinary medicine and to obtain reliable conclusions on the benefits of propolis in animal health and production.
