“…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.…”

“…Aspartate aminotransferase activity presented a cubic response, with an estimated increase from 21 to 24 days of age and a reduction up to 36 days, increasing again up to 42 days regardless of the environment (Figure 3). These results differ from those of Silva et al (2007), who observed a progressive increase in AST with age in broiler chickens, and those of Borsa et al (2006), who observed no effect of age on the variation of this enzyme.…”

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.

“…Blood plasma cholesterol level in cocks of laying lines ranges from 2.33 to 2.75 mmol/l, glucose in laying hens lines is between the values of 4.87 to 15.15 mmol/l (Máchal, 1999). Silva et al (2007) revealed content of creatinine in blood plasma in ranges from 46 to 59 µmol/l. Concentrations of plasma calcium in broiler chicken was from 2.52 to 3.80 mmol/l, phosphorus from 2.78 to 5.27 mmol/l, and plasma magnesium from 0.83 to 0.84 mmol/l (Večerek et al, 2002).…”

In domestic fowl (Gallus gallus f. domestica), monitoring of both quantitative and qualitative parameters of ejaculates is an indispensable precondition of successful artificial insemination; on the basis of the obtained results it is then possible to select the individuals that produce sufficient amounts AbstRAct: Ejaculates and blood plasma were sampled from cocks of three laying lines: Barred Plymouth Rock (BPR), Sussex Light (SU), and Rhode Island Red (RIR). Ejaculates and blood plasma were sampled four times during the laying period of hens. The following ejaculate parameters were determined: sperm motility, concentrations of sperm cells, ejaculate volume. Sperm morphology was examined. In the blood samples, concentrations of glucose, cholesterol, creatinine, calcium, phosphorus, and magnesium were analysed. The motility of spermatozoa of the cocks was 47.0% (BPR), 47.7% (RIR), and 48.3% (SU), respectively. The highest volume of ejaculate was found in BPR line (0.66 cm 3 ), the lowest one in SU line (0.46 cm 3 , P ≤ 0.01); the highest sperm concentration was in SU line (2.46 × 10 6 /mm 3 ), the lowest one in RIR line (1.96 × 10 6 /mm 3 , P ≤ 0.01). The number of morphologically abnormal sperm cells was similar in all lines − 47.0% BPR, 47.7% RIR, and 48.3% SU, respectively. In general, the occurrence of defective spermatozoa was high in all three lines; the most frequent were tail defects (from 20.3 to 29.7%), while sperm cells with developmental anomalies were less frequent (only 0.3 to 0.4%). Calculated phenotypic correlation between sperm motility on the one hand and the occurrence of defective sperm cells on the other was negative (r p = −0.28, P ≤ 0.01), as well as the correlation between sperm motility and sperm numbers, and between sperm motility and ejaculate volume (r p = −0.28, P ≤ 0.01 and r p = −0.31, P ≤ 0.01, respectively). Negative correlations were found between the level of magnesium in blood plasma and numbers of morphologically defective spermatozoa in the ejaculate, defective heads and defective connecting pieces (r p = −0.33, P ≤ 0.01; r p = −0.23, P ≤ 0.05; and r p = −0.26, P ≤ 0.05). Level of magnesium was positively correlated to sperm motility (r p = 0.26, P ≤ 0.05). However, positive correlations existed between concentration of glucose in blood plasma of cocks and numbers of morphologically defective spermatozoa in sampled ejaculates (r p = 0.27, P ≤ 0.01). Our finding is in accordance with the results found in mammals and other animals, and it shows an important role of magnesium as a key contributor to the quality of ejaculate in aviary species, in our case in laying lines of domestic fowl (Gallus domesticus).

Serum lipids (triglyceride, cholesterol, HDL cholesterol, LDL cholesterol, and VLDL) were measured in clinically healthy broilers, ostriches, cattle, and sheep (15 females and 15 males of each species).The results were as follows: the mean±SD of triglyceride, cholesterol, HDL-C, LDL-C, and VLDL in broiler serum was 190±82, 183±46, 118±24, 24±8, and 38±16 mg/dl; in ostrich serum 301± 90, 205±78, 57±25, and 87±16 mg/dl; in cattle serum 39± 1 2, 92±20, 67±16, 16±7, and 8±2 mg/dl; and in sheep serum 32±14, 97±27, 49±16, 42±14, and 6±3 mg/dl, respectively. The serum lipid values showed highly significant difference between broilers and ostriches compared with cattle and sheep (P<0.05). There were no significant differences between the two sexes (P>0.05). Considering the nutritional analysis of the meat from each species, according to results, there seems to be an inverse correlation between these factors in serum and meat.
