“…The quadratic effect was also observed in the animals subjected to stress but with an estimated increase from 21 to 25 days and decreasing until slaughter (Figure 1). This behavior is different from that reported by González et al (2001), who observed an increase of cholesterol at 47 days compared to 21 and 32 days, and from that reported by Silva et al (2007), who observed higher values of cholesterol up to 21 days, with a decrease at 35 days and an increase at 42 days.…”

This study aimed to evaluate the influence of age and cyclical heat stress for 1 hour per day on the levels of serum proteins, metabolites, and enzymes in broiler chickens of 21-42 days of age. We used 420 male broiler chickens, Cobb Avian48TM breed, in a completely randomized experimental design, composed of two treatments and six replicates. The treatments consisted of two thermal environments: one in which broiler chickens were raised under natural conditions of temperature and humidity for the first 42 days of age (control) and another in which chickens were subjected to heat stress at 36°C, from days 16 to 42, for 1 hour per day (1200-1300 hours). At 21, 28, 35, and 42 days of age, approximately 5 mL of blood was collected by cardiac puncture in two birds per replicate. In each serum sample, levels of total protein, albumin, globulin, albumin:globulin ratio, aspartate aminotransferase (AST), alanine aminotransferase (ALT), and gamma-glutamyltransferase (GGT) activity and uric acid, creatinine, total cholesterol, triglycerides, high-density lipoproteins (HDL), very low density lipoproteins (VLDL), low-density lipoproteins (LDL), and glucose levels were determined. Concerning the environment and the age, no significant differences in the levels of glucose, uric acid, ALT, triglycerides, and very low density lipoproteins were observed. There was a significant interaction between the environment and the age for cholesterol and LDL values. At 21 days of age, cholesterol and LDL-cholesterol (LDL-C) were higher in birds under stress than in the control treatment birds, which did not occur in other age groups. Aspartate aminotransferase activity was higher in chickens under cyclical heat stress than in chickens subjected to control treatment and displayed a cubic response regarding the environment. The age of the birds influenced the values of total protein, albumin, globulin, albumin:globulin (A:G) ratio, creatinine, GGT, and HDL. In conclusion, cyclical heat stress, at 36ºC, for one hour, from days 16 to 42 of age increases serum AST, whereas cholesterol and LDL-C levels increase only at day 21, indicating that birds may have adapted to heat stress. Age influenced the activity of AST and GGT and levels of creatinine, total protein, albumin, globulin, A:G ratio, cholesterol, HDL-C, and LDL-C. Key words: Poultry. Cholesterol. Liver enzymes.

ResumoObjetivou-se avaliar a influência da idade e do estresse cíclico por calor durante uma hora por dia, nas concentrações das proteínas, metabólitos e enzimas séricas em frangos de corte de 21 a 42 dias de idade. Foram utilizados 420 pintos de corte machos, da linhagem Cobb Avian48 TM , em um delineamento inteiramente casualizado, composto de dois tratamentos e seis repetições. Os tratamentos foram constituídos de dois ambientes térmicos: um para frangos de corte criados em condições naturais de temperatura e umidade do primeiro ao 42° dia de idade (controle); e outro para estressados por calor à 36 °C do 16° ao 42° dia, durante uma hora do dia (12h00m às 13...

“…The chicks fed diets with levels equal to or higher than 5% MWM showed a greater albumin level. However, the obtained results, 1.568 g dL -1 to 1.952 g dL -1 , were within the normal range, and this outcome was similar to the 1.54 to 1.9 g dL -1 found by González et al (2001).…”

“…Total cholesterol and albumin conformed to the values mentioned by González et al (2001), which were 95.6 to 131.2 mg dL -1 and 1.43 to 1.87 g dL -1 , respectively. The total protein content in the plasma of the birds was lower at the level of 10.0% of inclusion of MWM in the diets as compared with the control treatment.…”

We evaluated the effect of including 2.5, 5.0, 7.5 and 10.0% mango waste meal (MWM) variety UBA in corn and soybean meal-based diet on the serum lipid profile of broilers. The experimental design was completely randomized, with five treatments and six replicates with 20 birds per experimental unit. Concentrations of creatinine, albumin, total protein, total cholesterol, triacylglycerols (TAG), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C) and very-low-density lipoprotein cholesterol (VLDL-C), were evaluated at the ages of 14, 28 and 42 days, with 30 birds evaluated per age. At 14 days, there was no difference serum creatinine, total cholesterol, HDL, triacylglycerols, total proteins or VLDL-C concentrations as compared with control. Albumin concentration was the highest at the MWM inclusion levels of 5.0, 7.5 and 10.0%. At 28 days, triacylglycerols, VLDL-C and LDL-C were the lowestat 7.5% inclusion whereas at 42 days, these same variables were the lowest with addition of 10.0% meal. At 14, 28 and 42 days of age, the VLDL-C, LDL-C and total TAG contents were found to decrease at mango waste meal inclusion levels of 5.0 and 7.5% in the diets, which maybe considered an indicator of improvements in the metabolic conditions of broilers.

“…O perfil de frangos de corte acometidos por sinais compatíveis com síndrome ascítica mostrou depressão do metabolismo energético (depressão das fontes de energia, pois o animal vai perdendo o apetite gradativamente, devido à pressão causada pelo edema abdominal), evidenciado pela diminuição da glicose, colesterol e triglicerídeos (GONZÁLEZ et al, 2001). …”
