“…Aspartate aminotransferase is responsible for the synthesis of this metabolite. The enzyme is found at high concentrations in various organs and tissues, particularly in the heart, liver, skeletal muscle, kidney, and brain ( Kaneko et al, 2008 ; Rezende et al, 2019 ). According to MacRae et al (2006) , serum activity of this enzyme serves as an enzymatic marker of muscle changes, including both muscle damage and increases in muscle mass.…”

“…According to MacRae et al (2006) , serum activity of this enzyme serves as an enzymatic marker of muscle changes, including both muscle damage and increases in muscle mass. A study on broiler chickens demonstrated an increase in the serum levels of this enzyme during the final growth phase ( Rezende et al, 2019 ).…”

“…Stress, endogenous corticosterone, and endogenous steroid hormones can cause elevations in cholesterol levels in Darwin’s rhea [ 18 ]. A survey on the biochemical profile of broiler birds carried out a comparison of age groups and sex of these species and reported lower values of uric acid and cholesterol in males [ 32 ].…”

We investigated the biochemical profile of greater rheas (Rhea americana) in captivity and correlated these values according to the birds’ sex. A total of 69 serum samples were collected from a breeding site in Mossoró, northeastern Brazil, and analyzed to quantify serum biochemical parameters (total protein, albumin, cholesterol, calcium, phosphorus, uric acid, urea, creatinine, ALP, AST, and CK). The birds had levels of urea, creatinine, total cholesterol, aspartate aminotransferase, calcium, and phosphorus similar to the values reported for ratite and ostrich species. By sex, females showed higher values (p < 0.05) of calcium (3.5 mmol/L), total cholesterol (7.5 mmol/L), and uric acid (435.3 μmol/L) than males, which had 3.1 mmol/L, 3.8 mmol/L, and 390.7 μmol/L, respectively. This can be attributed to the difference in diet, the productive phase of females, or stress at the time of sampling. The data present a wide spectrum of biochemical results regarding the health of greater rheas, contributing to the veterinary clinical practice of this species.

“…At 21 days of age, a single fasting bird from each repetition (30 units in total) was taken for total blood glucose quantification (Rezende et al, 2019), with the use of a portable digital glucometer (G-Tech Lite ® , South Korea). Then, the birds were slaughtered and their organs (liver, pancreas, gizzard, and intestines) removed and weighed immediately.…”

Non-ruminantsFull-length research article Orange essential oil in the diet of broilers: performance, organ biometrics, bone characteristics, and intestinal morphometry ABSTRACT -Growth performance, organ biometrics, bone characteristics, and intestinal morphometry were evaluated in broilers fed a diet containing orange (Citrus sinensis L.) essential oil. A completely randomized design was used, with five treatments with orange essential oil (0, 100, 200, 300, and 400 mg kg −1 diet) and six replications with 20 birds per experimental unit. In the pre-starter phase, feed intake and weight gain of all birds linearly increased, while feed conversion decreased with the addition of orange essential oil in the feed. At day 21, bone density (Seedor Index) and body weight were higher in the birds that received the maximum level of essential oil (400 mg kg −1 ) compared with those not treated with essential oil. The observed effects resulted from the better functioning of the physiological mechanisms of digestion and absorption of nutrients, characterized by the increase in villus height. Glycemia and weights of gastrointestinal tract organs of broilers at 21 days of age were not influenced by the evaluated essential oil. The results show that the addition of phytogenic additives to the diet does not cause any physiological impairment in birds.
