This study was to investigate physicochemical characteristics, fatty acids, minerals and hematological alterations in broiler chickens artificially infected with 1 Â 10 4 sporulated oocysts of Eimeria tenella. Results revealed that pH values were decreased (p ˂ .05) in the infected group (IG) at 7 and 9 days post infection (dpi) than those at 5 dpi, although no significant differences between the non-infected group (NIG) and IG. Infection with E. tenella did not affect meat colour parameters except that redness was lower (p ˂ .05) than that in the NIG. Cooking loss was decreased (p ˂ .05) in NIG and IG at 7 and 9 dpi than that at 5 dpi. Thiobarbituric acid reactive substance (TBARS) value was increased (p ˂ .05) in IG at 7 dpi than 5 or 9 dpi and NIG (p ˂ .01). Total protein (TP) and total cholesterol (TC) were significantly lowered in IG at 5 dpi. Other blood parameter results showed decreases of glucose (GLU), triglyceride (TG), high-density lipoprotein (HDL), low-density lipoprotein (LDL) in infected chicken at 7 dpi compared to those in the NIG without significance. However, albumin (ALB) level was decreased (p ˂ .01) in the IG compared with NIG at 5 dpi. Levels of aspartate aminotransferase (AST) were lowered (p < .05) in the IG than NIG at 7 dpi. Mineral contents of Ca, Mg, Cu, and Zn were lowered (p ˂ .01) in the IG than those in the NIG at 7 dpi. Based on these results indicate that a low dose of E. tenella has no impact on meat quality traits, fatty acids although it can slightly affect blood parameters and mineral contents. HIGHLIGHTS The low dose of Eimeria tenella has no impact on meat quality traits and fatty acids of broiler meat. A significant increase in some blood parameter is observed in infected broiler chickens at 9 dpi. Mineral contents of Ca, Mg, Cu and Zn decreases in infected broiler meat at 7 dpi.
OBJECTIVE To determine pulmonary anthracosis in zoo, wildlife, and companion animals of Jeollabuk-do Province, South Korea. ANIMALS A total of 350 animals of 61 different species, belonging to 3 classes (mammals: n = 38; avian: 21; and reptiles: 2) from different habitats in Jeollabuk-do Province, were examined. PROCEDURES Gross lung examination and tissue sampling were done at postmortem, and histopathological analysis was microscopically done on hematoxylin and eosin–stained slides. RESULTS Macroscopic analysis of anthracotic lung tissue revealed minute (pinpoint size) spots and black pigmentation in a scattered and/or coalescing fashion. The presence of carbon particles was noted in 154 (44%, 154/350) cases. Based on habitation, zoo animals had the highest frequency of anthracosis in the lung (55.2%, 69/125), followed by companion animals (45.2%, 56/124) and wildlife animals (28.7%, 29/101). There was an association between habitation and the presence of anthracosis (P < .05). CLINICAL RELEVANCE This study revealed evidence that the presence of anthracosis is associated with the environmental air quality of zoo, wildlife, and companion animals in Jeollabuk-do Province, South Korea. Air pollution may affect the respiratory health of the endangered species at the Jeonju Zoo as well as the human population. Continuous monitoring of particulate matter and establishing policies that control industrialization around the province would enable quick action to curb any potential respiratory health risks to animals kept in the urban cities of the province.
