“…The behavioral evaluation method was of the instantaneous type (Catalan et al, 2013), that is, it was performed on stored video images from each partition of each cage according to the behavioral ethogram (Table 1), with duration of approximately 5 s of observation for each quail. Thus, the number of birds that were performing a certain category of behavior at that very time was recorded.…”

The objective of this work was to evaluate the combined effects of air temperature and air velocity on the behavior of Japanese quail (Coturnix coturnix japonica). A total of 216 Japanese quail in their initial laying phase were used. Bird behavior was categorized with an ethogram (eat, drink, stop, open wings/shiver, others). The experimental design was a randomized complete block, in a 4x4 factorial arrangement, with four air velocities (0, 1, 2, and 3 m s-1) and air temperatures (17, 23, 29, and 35°C). The behavior “stop” was greater when the birds were subjected to 17°C. At 35°C, a significant reduction (p<0.05) was observed in the behavior “eat” at 0 m s-1, compared with the other velocities. The behaviors of laying quail are similar in the morning and in the afternoon. Quail remain stopped for a longer time under cold stress conditions, at 17°C.

“…The effect of essential oils on the hepatic function of broilers is variable. Cinnamon, oregano, pepper, thyme (Toghyani et al, 2011;Attia et al, 2017b;2018), and ginseng (Catalan et al, 2013) oils do not influence hepatic biochemical components, such as serum protein, albumin, triglyceride, and AST. However, considering the conditions of this study, GGT levels (Table 4) may indicate hepatic damage in broilers, which may be associated with hepatic fibroplasia and hyperplasia of the bile ducts observed in groups that received rations with essential oils (Figure 1).…”

This study aimed to evaluate the hematological profile, hepatic function, and histopathology of mixed-sex broilers fed rations supplemented with microencapsulated essential oils from Cymbopogon flexuosus (lemon grass) and Lippia rotundifolia (chá-de-pedestre). One hundred and fifty Cobb chicks were housed in cages from 1 to 42 days of age in a completely randomized design, with six replicates with five chickens in each of five treatments (150 total chicks): basal diet without antibiotic growth promoter (negative control), diet with enramicina and salinomycin (positive control), diet with lemon grass essential oil, diet with L. rotundifolia essential oil, and diet with a mixture of lemon grass and L. rotundifolia essential oils. Mean corpuscular volume (MCV) and mean corpuscular hemoglobin (MCH) were significantly lower in untreated broilers (negative control group). Gender was not associated with erythrogram values, but aspartate aminotransferase activity (AST) was higher in females. Gamma-glutamyl transferase (GGT) was higher in chicks in the group that received rations with lemon grass oil. Broilers that received L. rotundifolia oil developed more hepatic lesions, although no effect of sex was observed related to the lesion score. Biliary hyperplasia and fibroplasias were observed in all groups, with higher histopathology scores in broilers that received diets containing L. rotundifolia oil. Mixed-sex broilers fed rations supplemented with lemon grass and L. rotundifolia essential oils have normal complete blood counts and unspecific hepatic lesions and are characterized by lipidosis, hyperplasia of the bile ducts, and fibroplasia.
