Abstract The present study was conducted to determine the effect of cage tier on laying performances, blood biochemical indicators, feather condition and antibody titers of layer breeders among different tiers in mating cages during the peak laying period. All birds (Hy-Line Brown parent stock breeders) at 27 weeks of age were housed in 4-tier mating cage. Laying performances, egg quality characteristics, blood biochemical indicators, antibody titers and feather condition were measured. The highest laying rate was recorded at 2nd tier, followed by 4th tier and 3rd tier, and the lowest at 1st tier. There were no significant differences among different tiers in terms of percentage of defective eggs and hatchability performances. Yolk color was significantly lower at 2nd tier than at other tiers. However, no distinct differences in egg weight, shell weight, shell color, shell breaking strength, egg shape index, yolk weight, albumen height, haugh units were observed. Concentrations of serum CK, T-AOC, SOD, GPx and MDA, and the antibody titers did not change substantially among different tiers. Moreover, the average feather score for each individual part of the body and an overall average score for birds were not significantly different. We confidently conclude that cage tier may be a contributing factor for layer performances. These findings will be helpful for application of natural mating system in layer industry.

Comparative study on egg production and hatchability characteristics in Nigerian local (NL; n=24), FUNAAB-α (F-α; n=24) and Transylvanian naked neck (TNN; n=24) chickens aged 25 weeks old was carried out for 4 weeks. Three hundred and sixty hatchable eggs each were used for quality characteristics determination and for incubation. F-α had significantly (P<0.001) higher egg production (90.3%) than TNN (76.9%) while TNN was higher than NL (58.3%). Egg weight (EWT), length, width and surface area, albumen height, weight, percentage and index, shell weight, color and internal quality unit (IQU) were significantly (P<0.001) affected by genotype. These followed the pattern: NL<F-α<TNN. F-α and TNN had significantly (P<0.001) higher values than NL in egg shape index, yolk weight, height and diameter. Yolk colour index was significantly (P<0.01) higher in TNN than in F-α. Yolk percentage and yolk-albumen ratio followed the pattern: NL>F-α>TNN. NL had (P<0.001) thicker and higher shell percentage (SP) than F-α and TNN. Higher Haugh unit (HU) was recorded in TNN than in NL and F-α. Fertility was significantly (P<0.05) higher in F-α than in TNN. Hatchability was not (P>0.05) affected by genotype. Chick weight and chick: egg ratio were significantly (P<0.001) by genotype. TNN had higher chick weight and yield than F-α and NL chicks. In conclusion, F-α laid more eggs than others, exhibited higher fertility with longer chicks at hatch. TNN is superior in EWT, HU, IQU and chick yield. NL had higher SP than others. Keywords: Egg production, Egg quality, FUNAAB alpha chicken, Hatchability, Transylvanian naked neck chicken.

The aim of this study was to evaluate the effect of three different chemical feed phosphates on the blood biochemical indicators and the content of main minerals of bones in finishing pigs. Over a period of 85 days of fattening, monocalcium (MCP, Finnish product), dicalcium (DCP, Polish product) and calcium-sodium (CSP, Russian product) phosphates were used in fattener feeding. The feeding was based on standard mixtures of starter, grower and finisher type. Dicalcium phosphate was produced according to the new, pro-ecological technology based on phosphoric acid. The content of Ca, Na, P, solubility of P in citric acid, and the concentration of undesirable substances (As, Cd, F, Hg and Pb) were determined in feed phosphates. At the end of the fattening period, blood was collected from 36 finishing pigs (12 from each group) and the following biochemical indicators were determined in the serum: enzymatic activity of aspartate aminotransferase (AST), alanine aminotransferase (ALT), γ-glutamyltransferase (GGT), creatine kinase (CK), lactic dehydrogenase (LDH), lactic acid (LA); the concentration of total protein, albumins, glucose, urea, creatinine, content of triglycerides, cholesterol and its high density lipoproteins (HDL) and low density lipoproteins (LDL) fractions, and mineral components concentration (Ca, Cl, Cu, Fe, K, Mg, Na, P, Zn). Basic macroelement content (Ca, Mg, P) was determined in the thigh bones from 30 pigs (10 from each group). Significant differences (p < 0.05) between groups were observed only in some biochemical indicators, i.e. CK, LDH and LA. The highest content of Ca, Mg and P was found in the bones of pigs fed mixtures supplemented with DCP which indicates improved bioavailability of main macroelements from that phosphate.

Background. The metabolic characteristics of body fluids of excellent water polo players before and after competition have not been reported. The purpose of the study was to compare the metabolites in the urine of water polo players before and after competition by 1H-NMR-based metabolomic approach. Methods. Twenty-six young water polo players participated in the study voluntarily. The urine and blood samples of players were collected one week before competition (A), immediately after competition (B), and one week after competition (C). Metabolomic analysis was conducted on the urine samples. Urine routine items and biochemical indicators in blood samples were detected. Results. Metabolomic results showed that the contents of eleven metabolites including lactic acid, acetoacetate, and succinic acid in the urine of the subjects increased and four metabolites such as dimethylamine, choline, and glucose decreased at stage B. Most metabolites at stage C had basically returned to the levels at stage A. Pyruvate metabolism, pantothenate and CoA biosynthesis, synthesis, and degradation of ketone bodies were mainly involved in the above process. Urine conventional analysis results showed that the urine pH decreased dramatically and the levels of PRO and URO significantly increased at stage B, and the three indicators had similar values between stages A and C. The other indicators did not have obvious difference among the three stages. Analysis of blood biochemical indicators showed that the levels of LDH, BUN, CK, and AST significantly increased at stage B and did not show an obvious difference between stages A and C. The results are helpful for coaches to arrange the athletes’ diet reasonably and to conduct scientific training for athletes.

Plasma-activated liquid (PAL) can effectively and selectively kill various types of cancer cells both in superficial and deeper tumors. As a promising novel approach to oncotherapy, the safety of PAL is essential in the clinic but has not been thoroughly assessed. In myeloma and blood tumors, the pathogenesis is in the bone marrow cavity. We have therefore evaluated the safety of PAL in New Zealand rabbits by intra-bone marrow injection, and provide a basis of further clinical research and application of PALs. In this study, both a plasma jet and plasma surface were used to treat saline solution, phosphate-buffered solution, and cell culture medium, to produce PAL. Then, oscillograms and optical emission spectra were evaluated to characterize the plasma discharge. Acute toxicity tests and safety evaluation studies were conducted by intra-bone marrow injection of PAL into New Zealand rabbits, while control rabbits received saline only. Body weight, vital organ coefficient, organ appearance, organ histopathology, blood cell and hemoglobin parameters, and blood biochemical indicators were tested on the 30th day after injection. We found that there was no mortality or loss of mobility throughout the experimental period. Acute toxicity tests showed that there were no PAL-related side effects in rabbits receiving the maximum dose of 700 μL PAL. PAL treatments did not affect body weight, organ coefficient, organ appearance, organ histopathology, or blood biochemical indicators. However, the percentage of lymphocytes decreased while the percentage of neutrophil granulocytes increased compared with the control group. In summary, our results indicate that PAL can be safely injected into bone marrow of New Zealand rabbits without significant toxicity.

The aim of the study was to determine the effect of type of alternative housing system and layer genotype on the quality of table eggs. The investigated eggs came from native Greenleg Partridge hens (Z-11) and Rhode Island Red hens (R-11) covered by the gene-pool protection program, as well as from Hy-line Brown commercial hens from litter barn (LS), free range (FR), and organic systems (OS). Eggs for the study were collected from the hens at 56 wk of age. Egg quality assessment was based on the following values egg traits: weight, shape index, yolk, albumen, and shell percentage in the whole egg; eggshell traits: color intensity, weight, thickness, density, breaking strength, physical features of egg content: albumen height, value of Haugh units, yolk color; presence of meat/ blood spots and cholesterol, higher fatty acids, vitamin A and E in egg yolks. In the rearing systems under study, eggs with the highest weight were laid by commercial hens, and the type of alternative rearing system had no significant effect on this trait. Shell colour intensity depends on the breed of hen, whereas the rearing system has no significant effect on this trait. Hen genotype and housing system had an effect on egg shell weight, thickness, and density. The housing system influences the content of MUFA, PUFA, PUFAn-6 and PUFAn-3 as well as PUFA 6/3 in egg yolks. No effect of the housing system on egg yolk cholesterol content was observed.

Изучили биохимический статус организма быков-производителей голштинской (n=8) и симментальской (n=8) пород в сравнительном аспекте. Проанализированы пробы сыворотки крови быков-производителей, содержащихся в условиях племпредприятия Московской области. В образцах крови определяли показатели азотистого, углеводно-липидного, минерального обменов, активность ферментов. Содержание общего белка и его фракций, мочевины, а также соотношение альбуминов и глобулинов были примерно на одном уровне независимо от генотипа животных. В крови быков симментальской породы, по сравнению с аналогами голштинской породы, была выше концентрация креатинина на 19,9% (P<0,05), уровень фосфолипидов — на 16%, холестерин — на 46,5% (P<0,05). Концентрация фосфора в сыворотке крови симментальских быков составляла 2,52 мМ/л, что на 30,5% больше, чем у голштинов (P<0,05). Отношение кальция к фосфору в организме симментальских быков равнялось 1,04 против 1,40 ед. в группе голшинских быков. Полученные данные указывают на различия в протекании азотистого, углеводно-липидного и минерального обменов в организме животных мясо-молочного и молочного направлений продуктивности и помогут в разработке эталонных значений биохимических показателей крови для оценки здоровья и уровня питания быков-производителей изучаемых пород. We studied the biochemical status of the organism of Holstein (n=8) and Simmental (n=8) bulls-producers in a comparative aspect. Samples of blood serum of bulls-producers contained in the conditions of the Moscow region were analyzed. Indicators of nitrogen, carbohydrate-lipid, mineral metabolism, and enzyme activity were determined in the blood samples. The content of total protein and its fractions, urea, as well as the ratio of albumins and globulins were approximately at the same level, regardless of the genotype of animals. In the blood of Simmental bulls, compared with analogues of the Holstein breed, the concentration of creatinine was higher by 19.9% (P<0.05), the level of phospholipids — by 16%, and cholesterol — by 46.5% (P<0.05). The concentration of phosphorus in the blood serum of Simmental bulls was 2.52 mmol/l, which is 30.5% higher than in Holsteins bulls (P<0.05). The ratio of calcium to phosphorus in the body of Simmental bulls was 1.04 against 1.40 units. in the Holstein bulls. The obtained data indicate differences in the nitrogen, carbohydrate-lipid and mineral metabolism in the body of animals of meat-and-milk and dairy productivity and will help in the reference values of blood biochemical indicators development for assessing the health and nutrition level of bulls-producers of the studied breeds.
