The introduction of feed for poultry carotenoids that are not transformed in the body, including lycopene and astaxanthin, causes an attractive commercial appearance of chicken egg yolks. The production of high-quality and safe table eggs involves limiting the use of synthetic yolk dyes and switching to natural dyes, including tomato and seaweed products. The aim of this study was to determine the egg productivity of poultry, morphological composition of eggs, as well as feed and water intake with the addition of oil extracts of lycopene (20, 40 and 60 mg/kg or feed) or astaxanthin (10, 20 and 30 mg/kg of feed) to the diet. laying hens. The experiment was performed on 45 chickens of the High Line W36 cross at the age of 24 weeks. Each additive was fed to laying hens for 30 days in increasing concentrations. The use of lycopene or astaxanthin in different doses to laying hens did not have a negative impact on the clinical condition of the bird and behavior, did not cause death of birds of the experimental groups throughout the experiment. The condition of feathers and visible mucous membranes in chickens during the use of experimental diets was characteristic of clinically healthy birds. It was found that the addition of lycopene at doses of 20, 40 and 60 mg/kg and astaxanthin at doses of 10, 20 and 30 mg/kg of compound feed for 30 days did not significantly affect feed consumption and egg productivity. Increasing the content of astaxanthin to 20 and 30 mg/kg of compound feed, as well as lycopene to 60 mg/kg of compound feed resulted in a slight decrease in water consumption by laying hens. Feeding laying hens supplements of astaxanthin oil extract at doses of 10, 20 and 30 mg/kg or lycopene at doses of 20, 40 and 60 mg/kg of compound feed for 90 days did not significantly affect the weight of eggs, as well as the weight of protein, yolk and shell. Additions of lycopene and astaxanthin oil extracts to the diet of laying hens may be promising for use in correcting the color of egg yolks.

Ensuring an attractive commercial appearance of egg yolks involves the introduction to the feed of laying hens of the dyes of various origins. Recently, egg producers have preferred natural dyes, which include carotenoids: lycopene and astaxanthin, which can be deposited in chicken egg yolks. The aim of this study was to determine the quality of egg yolks, colour intensity and carotenoid composition of yolks when oil extracts of lycopene (20, 40 and 60 mg/kg feed) or astaxanthin (10, 20 and 30 mg/kg feed) are included in the chickens’ diet. 45 High Line W36 chickens at the age of 24 weeks were used for the experiment. Feeding laying hens with supplements of lycopene oil extracts at doses of 30, 40 and 60 mg/kg and astaxanthin at doses of 10, 20 and 30 mg/kg of feed for 30 days in increasing concentrations did not affect egg weight, albumen height, Haugh unit, strength and the thickness of the shell. The addition of lycopene to the diet of chickens at doses of 20 mg/kg of feed increased the content of lycopene, unidentified carotenoids and the total content of carotenoids in the yolks, but did not change the intensity of their colour. Increasing the dose of lycopene in the diet of chickens to 40 and 60 mg/kg of feed increased the content of lycopene in yolks and the intensity of their colour to 7.4 and 8.0 points against 5.6–6.1 points in the control, but did not affect the content of β-carotene and total carotenoids in the yolks. The addition of astaxanthin oil extract at doses of 10, 20 and 30 mg/kg of feed increased the content of astaxanthin, β-carotene and total carotenoids in chicken egg yolks and increased the intensity of their colour to 12.8, 14.8 and 14.4 points on a 16-point colour scale YolkFanTM. To obtain chicken table eggs with a given colour of the yolks, it is advisable to use the addition of astaxanthin oil extract in doses from 10 to 20 mg/kg of feed for 30 days. The results of the research can be used to develop a technology for the production of functional table eggs enriched with carotenoids of natural origin with an attractive colour for consumers.

Carotenoids that do not have provitamin activity – lycopene and astaxanthin can accumulate in the yolks of chicken eggs and give them colour, as well as affect the metabolism of lipids and fatty acids, which determine the biological value and functional capacity of such products. The aim of this study was to determine the fatty acid composition of egg yolk lipids by adding oily extracts of lycopene (20, 40 and 60 mg/kg feed) or astaxanthin (10, 20 and 30 mg/kg feed) to the diet of laying hens. 45 High Line W36 chickens at the age of 24 weeks were used for the experiment. It was found that the addition of lycopene at doses of 20, 40 and 60 mg/kg and astaxanthin at doses of 10, 20 and 30 mg/kg of feed for 30 days did not significantly affect the ratio of saturated and most monounsaturated fatty acids in egg yolks and Σ SFA and Σ MUFA. Lycopene at a dose of 20 mg/kg of feed reduced the content of cis-11-eicosenoic acid, and astaxanthin at a dose of 10 mg/kg of feed reduced the content of palmitoleic acid by increasing the proportion of cis-10-heptadecenoic acid in the lipids of egg yolks. Addition of lycopene to the feed of laying hens at a dose of 20 mg/kg of feed caused a decrease in the particles of linoleic, which belongs to ω6 PUFA, and cis-eicosenoic acids. Astaxanthin enrichment of the diet of laying hens at a dose of 30 mg/kg reduced the proportion of cis-4,7,10,13,16,19-docosahexaenoic acid, which belongs to ω3 PUFA, in the lipids of the yolks. Σ PUFA decreased in the lipid fraction of yolks only under the influence of lycopene supplements at a dose of 20 mg/kg of feed. Feeding of laying hens with lycopene and astaxanthin supplements did not affect Σ ω3 PUFA and Σ ω6 PUFA. Lycopene at a dose of 20 mg/kg decreased, and astaxanthin at a dose of 30 mg/kg of feed increased ω3/ω6 PUFA in lipids of egg yolks. The results of the research can be used to select oils in combination with carotenoids of natural origin in the diet of chickens during the creation of a model of enrichment of egg yolks by individual representatives of ω3 PUFA and ω6 PUFA.

Purpose. To study of the effectiveness of feeding high-yielding cows in the last 100 days of lactation of different levels and sources of zinc, manganese and cobalt and establish their impact on milk productivity, feed digestibility and nitrogen balance. Methods. Five groups of highly productive cows (one control and four experimental) of Holstein, Ukrainian red-spotted and Ukrainian black-spotted dairy breeds were selected for the experiment at “Terezyne” farm, Bila Tserkva district, Kyiv region. Experimental cows were fed the same rations. The difference was in different doses of mixed ligand complexes of trace elements in the premix. The control was the optimal dose of mixed-ligand complexes of zinc, manganese and cobalt, which was established in a previous experiment with a concentration of 1 kg of dry matter (DM) of feed, mg: zinc – 50, manganese – 50 and cobalt – 0.78. Results. It was found that the use of different doses of mixed ligand complexes of zinc, manganese and cobalt using Suplex selenium and copper sulfate and potassium iodide in feeding cows in the last 100 days of lactation have differently affected their milk productivity. If 2320 kg of milk was milked from each cow of the control group during this period, then from cows of the 2nd-5th experimental groups – 40-220 kg more. The difference in the average daily milk yield of 4% fat was 0.5-2.67 kg and it was significant (P <0.001). The results of the balance experiment show that the animals of the experimental groups better digested feed nutrients and absorbed nitrogen. Thus, in cows of the 2nd, 3rd, 4th and 5th experimental groups nitrogen was deposited in the body respectively by 2.1, 4.1, 7.3 and 12.8 g more, and it was statistically significant (P <0,05) compared with animals of the control group. Conclusions. The use of mixed ligand complexes of zinc, manganese and cobalt helps to increase milk productivity of cows, reduce feed consumption per 1 kg of product and reduces the need of animals for these elements. The best performance results were obtained in the 4th experimental group, the animals of which were fed with a feed mixture containing 1 kg of DM, mg: zinc – 35; manganese – 35; cobalt – 0.4; selenium – 0.3; copper – 9 and iodine – 0.8.

The treatment during the embryonic preimplantation phase of Wistar rats with thePradosia huberiextract did not interfere with the water and feed consumption, as well as upon the body-weight gain. However, it has expressed a decrease of the uterine implant number, followed by the preimplantation losses at all applied doses (1.22, 6.1, and 30.5 mg/kg), and the number of embryonic resorptions in the two highest doses (6.1 and 30.5 mg/kg). After the organ weighing (hypophysis, ovaries, and uterus), only the relative weight of the hypophysis was raised at the different doses (1.22, 6.1, and 30.5 mg/kg). It was concluded that the hydroalcoholic extract ofPradosia hubericompromises the reproductive ability during the embryonic preimplantation phase, suggesting a possible toxic effect upon the reproductive system of Wistar rats.

The present study investigated the effect of 1 and 2% feed supplementation with biomass of Chlorella grown through heterotrophic fermentation on the concentration of total and individual carotenoids in egg yolks. A total of twenty-four Hisex Brown laying hens aged 56 weeks were included in the experiment. The layers were kept individually in cages. They were divided into three groups of eight birds and fed a diet typical for laying hens. Control birds (C) received only a basal diet, while experimental diets (P1 and P2) were supplemented with 1 and 2% (i.e. 10 and 20 g/kg) dry disintegrated Chlorella biomass. Egg yolk deposition of total carotenoids was significantly (P &lt; 0.01) increased by 46% (P1) and 119% (P2). The rising curves of total carotenoids reached their plateau during the fourth experimental week. The respective values oscillated around 25&nbsp;mg (P1) and 40 mg (P2) per g of yolk during the following weeks. Lutein and zeaxanthin were equally deposited and they represented more than 90% of total carotenoids in yolk. The deposition of carotenoids significantly (P &lt; 0.01) increased the colour characteristics of yolks measured using the Roche Yolk Colour Fan scale. Supplementation with Chlorella biomass significantly decreased the egg yolk weight of P2 in comparison with P1 (P &lt; 0.05) and C (P &lt; 0.01). These effects were probably related to lower feed consumption in these hens. The daily feed intake per hen, as well as its consumption per egg, was lower by 5&ndash;7 g in both supplemented groups. Recalculation of the diet consumption per kg of egg and yolk mass eliminated these differences. There were no differences among laying hens in plasma concentrations of triacylglycerol and cholesterol.

ABSTRACT The effect of three doses of prednisolone and ACTH respectively on the weight of the body, the lungs and the hilar lymph nodes was studied on rats killed one month after the intratracheal (i.t.) injection of 50 mg of fine-particulate quartz. The prednisolone was administered via the drinking water, and the ACTH was injected intraperitoneally during the period between the i.t. injection of quartz dust and the killing of the animals. Prednisolone causes the rats to become cachectic and reduces the weight of the hilar lymph nodes. It also retards the transport of quartz dust from the lungs via the lymphatics. All these effects increase with increasing doses of prednisolone. However, its effect on the lung weight is insignificant. ACTH does not affect the body weight, but retards the weight increase of the lungs and the hilar lymph nodes. These effects increase with increasing doses of ACTH, and seem to be connected with an ability of ACTH to promote the clearance of quartz dust from the lungs and hilar lymph nodes. The method used, however, does not make it possible to differentiate quantitatively between any ACTH effects on the bronchogenie and lymphatic lung-clearance mechanisms. Available data, however, indicate that the stimulation of the dust transport from the lungs and hilar lymph nodes is, at least to some extent, related to the lymphatic system.

Abstract: The presence of epistemology in western philosophy is very influential in life, especially in regulating the strategy of power or power to achieve goals. The style of western thought brought a big change in the knowledge of thinking, perspectives, and behavior that became the motors of civilization. Two main influential schools in the study of western philosophy such as rationalism and empiricism are conflicting. Both favor reason and five senses, but also inseparable from the weaknesses of each that will be revealed by researchers. Likewise the negative impact behind the superiority of western epistemology on the nature and development and existence of humans.
