The aim of the study was to determine the influence of Cu-glycine chelate on the chemical composition of the liver and blood parameters of broiler chickens. A total of 250 one-day-old Ross 308 male chicks were allotted into 5 groups with 5 replicates of 10 birds each. Rearing of birds lasted 42 days. In the experiment Cu was added to the premix in the form of CuSO4 (16 mg, 8 mg Cu), and in the form of Cu glycine chelate (16 mg, 8 mg, 4 mg Cu). The parameters in the chickens’ blood remained within the range of physiological norms when lower levels of the analyzed elements were added. Adding lower levels of Cu (8 or 4 mg kg-1) in comparison with the recommended doses (16 mg kg-1) for broilers, in the form of highly assimilable organic sources, did not reduce the content of minerals Cu, Fe, and Zn in the chickens’ liver, but reduced the faecal Fe, Cu and Zn concentrations compared to CuSO4.

This research aimed at generating and evaluating prediction equations to estimate metabolizable energy values in poultry offal meal. The used information refers to values of apparent and true metabolizable energy corrected for nitrogen balance (AMEn and TMEn) and for chemical composition of poultry offal meal. The literature review only included published papers on poultry offal meal developed in Brazil, and that had AMEn and TMEn values obtained by the total excreta collection method from growing broiler chickens and the chemical composition in crude protein (CP), ether extract (EE), mineral matter (MM), gross energy (GE), calcium (Ca) and phosphorus (P). The general equation obtained to estimate AMEn values of poultry offal meal was: AMEn = -2315.69 + 31.4439(CP) + 29.7697(MM) + 0.7689(GE) - 49.3611(Ca), R² = 72%. For meals with high fat contents (higher than 15%) and low mineral matter contents (lower than 10%), it is suggest the use of the equation AMEn = + 3245.07 + 46.8428(EE), R² = 76%, and for meals with high mineral matter content (higher than 10%), it is suggest the equations AMEn = 4059.15 - 440.397(P), R² = 82%. To estimate values of TMEn, it is suggested for meals with high mineral matter content the equation: TMEn = 5092.57 - 115.647(MM), R² = 78%, and for those with low contents of this component, the option is the equation: TMEn = 3617.83 - 15.7988(CP) - 18.2323(EE) - 96.3884(MM) + 0.4874(GE), R² = 76%.

Energy Dispersion X-Ray Fluorescence Technique (EDXRF) was employed to study the effects of the fumagina disease on the elementary chemical composition of the leaves. The experimental set up consisted of a Mo X-ray tube (Ksub<FONT FACE=Symbol>µ</FONT> = 17.44 keV) with Zr filter and a Si (Li) detector. The measurements were performed with the infected and healthy leaves of citric plants. The elements Ti, Mn, Fe, Cu and Zn were quantified, with an average DL of 69, 12, 8, 4 and 4 µg.g-1 respectively. The obtained concentration for Fe varied from 44 to 192 µg.g-1 in healthy leaves and from 363 to 704 µg.g-1 in infected leaves with fumagina .

The effect of various dosages of the extract of the thyme medicinal plant on the slaughter qualities and the chemical composition of the meat of broiler chickens has been studied. The preparation was obtained by the method of water-ethanol extraction followed by low-temperature drying at the Agroecologia research laboratory of the Kuzbass State Agricultural Academy. The scientific economic experiment with the duration of 40 days was performed with broiler chickens of the Hubbard ISA F 15 cross at the broiler farm. One reference and five experimental groups of day-old broiler chickens were formed, 37 chickens in each group. The chickens in the reference group received basic diet, while the broilers in the experimental groups additionally received thyme extract in the following daily dosages: the first — 2 mg/kg, the second — 4 mg/kg, the third — 6 mg/kg, the fourth — 8 mg/kg, and the fifth — 10 mg/kg of body weight. At the end of the studies, the positive effect of feeding thyme extract on the characteristics of anatomical dissection of broiler chickens' carcasses was found. In the third, the fourth, and the fifth experimental groups, no significant differences were found, compared to the reference group. By the results of dispersion analysis of the data, a significant effect of thyme extract on the contents of lysine, threonine, and methionine has been found by the amino acid composition of the meat of broiler chickens.

This study investigated the genetic variation in carcass traits and blood parameters of local naked neck and normal-feathered chickens and their crosses with Marshall broiler chickens. Two hundred and sixty three chickens consisting of 50 purebred Marshalls (M), 38 naked neck (Nk) and 48 normal-feathered (N), 61Marshall x naked neck (MNk) and 66Marshall x normal-feathered(MN) chickens were used for the study. Data were collected on carcass traits, haematology and serum biochemical parameters and were analysed using the General Linear Model procedure of Statistical Analysis System. Carcass traits such as eviscerated weight and weights of thigh, drumstick, breast, wings and organs were significantly (P < 0.0001) affected by genotype. Results showed that the purebred Marshall had the highest values in most of the traits followed by their crossbreds. In organs such as gizzard, liver and heart the local normal feathered ranked equal with its crossbred. Sex significantly (P< 0.05) affected carcass traits. Males consistently had higher values than females in all the parameters measured. Genotype significantly (P
