The objective of this study was to assess the effect of copaiba oils (Copaifera reticulata and Copaifera duckei) on the health and performance of broiler chicks along with their anti-inflammatory activity. The experiment was performed in duplicate, using 60 chicks at a time. Groups were formed by broiler chicks fed with basal diet (control); basal diet and antibiotic (zinc bacitracin, 25 mg/kg of feed); basal diet and copaiba oil (0.15 mL/kg of feed); and basal diet and copaiba oil (0.30 mL/kg of feed) for 15 days. Sampling was performed on days 7 and 15 of life. Animals treated with 0.15 mL/kg of copaiba showed higher body weight (p 0.05); however, glucose and triglyceride levels were reduced on days 7 and 15 in animals that received copaiba oil, respectively (p

Mammary gland tumors are among the most frequently diagnosed neoplasms in female dogs. However, they are rare in male dogs, with incidence ranging from 0 to 2.7% (less than 1% on average). The triggering factors in males are still obscure, but studies have shown that hormonal abnormalities, especially those associated with testicular neoplasms, predispose towards their occurrence. Among the most common histological types diagnosed in males, adenocarcinoma, papillary cystadenocarcinoma, carcinosarcoma, simple adenoma, and spindle cell sarcoma can be highlighted. However, there are no reports of carcinoma “in situ” in males and its incidence in females is low. The present study reports a case of carcinoma in situ in a 13-year-old mixed-breed male dog, comprising a mammary gland tumor associated with mastitis, together with two histologically distinct tumors in the testicles (one in each): one was a diffuse seminoma and the other, a solid interstitial cell tumor. The present report is novel because of the histology of the mammary gland tumor.

Some challenge has been faced by farmers and among them are the decline of animal performance and mortality rate in the growth phase. One of the main causes of low performance is gastrointestinal problems, most of them caused by parasitic infections. Among the protozoa of major importance that affect the poultry in the first weeks of life, stands out the genus Eimeria, a parasite that causes intestinal malabsorption. The current study used 40 chicks, 1-day old, separated into four groups that received the same diet with different levels of yucca extract and glutamine supplementation. The animals were weighed at 10 and 15 days of age, where five chicks per group were used to evaluate the presence of oocysts, intestinal lesions, and biochemical variables. The addition of glutamine and yucca extract caused positive effect controlling coccidiosis, decreasing the presence of oocysts in both periods (Friedman = 37; p = 0.001); in addition, both served to protect the gut against the injury caused by the infection. Increased total protein values on day 15 (Friedman = 12; p

The aim of this study was to evaluate the activity of butyrylcholinesterase (BChE) in dairy cows naturally infected by Dictyocaulus viviparus and treated with eprinomectin. Among 22 serum samples, 10 were of animals with mild clinical disease and 12 with severe clinical disease. The samples were collect on days 0 (day of diagnosis) and 10 post-treatment (a single dose of eprinomectin [360 μg/kg, topically]). We evaluated the activity of BChE, alanine aminotransferase (ALT), aminotransferase andaspartate (AST), and gamma-glutamyl transferase (GGT) in serum. There was no significant difference between groups with different degrees of clinical disease (mild and severe) for the activity of BChE (p > 0.05). However, when considering the treatment (before and after), a significant difference was identified in the activity of BChE (p 0.05), was found. Based on these results, we can conclude that the treatment D. viviparus leads to a decrease of BChE activity, probably due to decrease in the inflammatory response in response to clinical improvement.
