This paper deals with normal values of some serum biochemical parameters in chickens and laying hens with regard to their age and sex. Investigations were performed on clinically healthy multipurpose birds of the Astra S race, both females and males aged 1-23 and 1-18 weeks, respectively. In serum of blood collected from the animals, levels of total protein, glucose, total cholesterol, triglycerides, calcium (Ca) and inorganic phosphorus as well as the activity of some enzymes including aspartate aminotransferase (AST), alkaline phosphatase (AP), lactate dehydrogenase (LDH) and creatine kinase (CK) were determined. In the birds of both sexes, some parameters were found to be age-dependent, including levels of total protein (increasing with age), cholesterol and triglycerides and CK activity (the highest levels were noted in 1-week old animals) as well as inorganic phosphorus and AP activity (decreasing with age). In the females beyond the 14th week of age, sex-dependent changes included an increase in levels of total protein, triglycerides and Ca as well as a higher level of phosphorus than that found in the males. No correlation between glucose level, AST, LDH activity, and the age and sex of the birds was observed.

Monitoring the health of dairy herds is central to the assessment of animal health and welfare. The aim of this study was to analyse hematological and biochemical parameters in Holstein-Friesian dairy cows depending on the management system.Thirty cows from the foundation stock with an average annual yield of 6500-7000 l of milk were selected for the experiment. The cows were characterized by similar yields and were in a similar lactation period (second and third lactation). The cows were divided into three groups of 10 cows each: confined to a barn (control group C), housed in a barn with free access to an outdoor run (O) and maintained on a pasture (P). Blood samples to determine hematological and biochemical parameters were collected from animals on an empty stomach before the onset of the experiment and towards the end of the pasture period. The present study showed a positive effect of pasturing dairy cows on their hematological parameters. In the group of pasture-fed cows, there were also significant (P≤0.05) differences between the results before and at the end of the trial. There was a significant(P≤0.05) increase in total white blood cell count and in basophil and neutrophil percentages. There were also significant (P≤0.05) increases in the concentration of hemoglobin (by 8%) and hematocrit (by 7%). Biochemical analysis showed slightly higher urea concentrations in the group of pastured cows when compared to the other groups. The high content of nitrogen compounds in the pasture forage could have a certain effect on hepatic nitrogen metabolism, which could increase serum concentrations of AST and ALT enzymes in cows from group P.

Scientific research has demonstrated that different compounds containing copper are capable of stimulating body weight gains, improving the health of animals and attaining high production performance without causing excessive accumulation of various chemical compounds in animal tissues. Besides, copper has been reported to exert a positive effect on the immune system, haematological blood markers and the microbiological balance in the gastrointestinal tract of turkeys. The experiment was conducted on 60 BUT-9 line turkeys. The birds were divided into 5 experimental groups. Each group included 12 turkeys kept in cages. The bird were reared for 19 weeks. The first group served as control. Group II received CuSO4 added to water in a dose of 10 mg Cu dm–3 H2O. Group III was com posed of birds administered a Cu chelate with lysine in a dose of 10 mg Cu dm–3 H2O. Group IV received CuSO4 in a dose of 20 mg Cu dm–3 H2O, whereas group V were given a Cu-lysine supplement in a dose of 20 mg Cu dm–3 H2O. The birds were fed commercial complete feed mixes. The copper preparations were added to drinking water since the 3rd week of rearing. The objective of this study has been to determine the effect of Cu supplementation in the organic and inorganic form and in two doses on the health of birds and on accumulation of minerals in their breast muscle and liver. Further analyses involved the determination of haematological and biochemical markers in blood as well as assays of selected minerals in the birds’ blood, breast muscle and liver. The analysis of the results indicated that the doses of copper improved the health of the turkeys, as verified by better haematological markers. Statistically significant difference appeared in the group receiving 20 mg Cu dm–3 H2O irrespective of the chemical form in which copper was administered. The study also shows that Cu supplementation has a significant effect on the metabolism of lipids and a non-significant impact on the content of mineral elements in the analyzed tissues. It was not until the 20 mg dose of Cu as a chelate had been applied that the accumulation of copper in the turkey’s liver was enhanced.
