Introduction. The aim is scientific justification and innovative technologies of aqueous-alcoholic infusions (AAI) for producing syrups in confectionery products, for giving them functional and health qualities. Materials and methods. Methods of investigation: redoxometry-determination of antioxidant capacity of AAI from plant raw materials; pH-metry; methods of determining of the organoleptic indicators. Results and discussion. The minimal theoretically expected meaning of Eh min for plant water-alcohol extracts was got, which has meanings from 203,0 mV (ginger root) to 480,9 mV (Sudan rose), and actually measured Eh act-82,0 mV (strawberry leaves) to 246,0 mV (ginger root). Thus, the minimum quantity of redox reaction (RR) is-42,3 mV and typical for ginger root, and the highest meaning 266,0 mV has the AAI from guilder rose fruits. The pH level for AAI has meaning from 2,985 (Sudanese rose) to 7,605 (ginger root) that infusios have reactions from acidic to slightly alkaline. The groups of infusions for antioxidant ability were defined: infusions with low activity-3 samples (25%), among them are ginger roots, apple fruits, elderberry fruits; infusions with middle activity-4 samples (33%), among them the lowest meaning 133,4 mV has cinnamon, and the most-171,8 mV has cherry leaves; infusions with the high activity-5 samples (42%), among them are rowan-234,3 mV, cherry-247,5 mV, Sudanese rose-260,4 mV, guelder rose-266 mV and buckthorn-282,4 mV. Conclusion. The most promising sources of natural antioxidants for usage in syrups technology for impregnation of confectionery product were defined.

It was found that the lowest percentage of cows with mastitis was recorded in winter: 10.3% (P≤0.001) when milking with ‘De Laval’ equipment and 17.7% (P≤0.001) when milking with the ADM-8A unit. The highest incidence of mastitis in cows was observed in summer: 21.0% (P≤0.001) and 27.1% (P≤0.001), respectively, when milking cows at milking parlors ‘De Laval’ and ADM-8A. It was found that, when using milking equipment ADM-8A, adult cows are 2.1-1.7 times more prone to mastitis compared to cows of the 1st and 2nd calving. When milking cows with the ‘De Laval’ unit, the incidence of mastitis in adult cows is 4.3-1.1 times higher than in cows of the 1st and 2nd calving. Gentle milking mode on the ‘De Laval’ equipment allowed to increase the number of completely healthy animals to 74%, which is 9.6% more than when using the milking unit ADM-8A (64.4%), and to reduce the incidence of clinical mastitis in cows by 3.4 times. It has been established that in cows with disorders in the udder the content of somatic cells in the secretion of the udder significantly changes (with a high degree of correlation) in all periods of the functional state of the body. Thus, during subclinical mastitis r=l0.72 (P≤0.001) and udder irritation r=l0.58 (P≤0.05). At the beginning of lactation, subclinical mastitis is accompanied with significant changes in the activity of enzymes: muramidase r=l0.84 (P≤0.001), lactoperoxidase r=l0.65 (P≤0.01) and lactoferrin r=l0.66 (P≤0.01).

To increase the productivity of cows and improve the nutritional and sanitary-technological qualities of milk is one of the most important tasks in the development of dairy farming in all countries of the world. The cause of degradation of these parameters is such a widespread disease of cows as mastitis. The social significance of mastitis is manifested in the fact that the causative agents of mastitis in cows can cause disease in humans. Since streptococci and staphylococci play a leading role in mastitis, they are the most common in milk. Studies have shown that udder disease in cows with mastitis at the beginning of lactation has a certain seasonal nature and its main peaks occur in March-May and September-November. During these months, from 2.5% to 4.1% of cows from the total number of livestock of the farm were found to have mastitis. Physiochemical features of milk from the cows with mastitis were an increase in the number of somatic cells to 1,500,000/cm3, increase of milk pH to 7.3, caused by the breakdown of milk proteins into ammonia, the increase in milk electrical conductivity to 5.92-7.54 mS/cm, associated with the entry of sodium and chlorine ions from the blood into the milk. In studies of cows with mastitis, 16 species of bacteria were isolated from the secretion of the udder. In monoculture, the microflora, that was found in 30.5% of cows, consisted of E. coli, St. epidermidis, C. freundi, Sh. Dysentery, St. aureus, St. hyicus spp. Chromogenes, Str. Agalactiae, St. lentus, and St. intermediate. In 69.5% of cows with mastitis, the microflora was found in various associations. The most common associations of bacteria were St. epidermidis + St. aureus + Str. agalactiae + Str. haemolyticus; E. coli + Str. agalactiae; Str. agalactiae + St. epidermidis; St. epidermidis + St. aureus + Str. agalactiae. We developed a method for diagnosing mastitis in cows, which was to diagnose the disease at early stage of inflammation of the mammary glands by studying the composition of the milk the examined lobe of the udder.

Recently, due to the widespread implementation of intensive milk production technologies, the requirements for the type of animal physique have increased, because the theory and practice of breeding have proved that the economic and long-term use of cows is not possible without taking into account their exterior features and type of the constitution. The influence of the traits of the animals’ physique on the duration of their economic use was studied, and the main slaughter grades and standards minimum percentage of cows determined beaf cow culling were determined. We selected the criteria mainly caused the cattle removing from the herd: growth scale of score 4, sacral inclination – score 6, limb posture from rear and side views - score 5. The percentage of cattle culling with body condition score score ranged from 7 to 9 was determined.

Improving modern dairy farming is based on the industry's development, which means transforming livestock farming into a competitive industry. The development of its technical and technological support is closely related to its functional ability to realize the genetic potential of biological objects of production with high-quality products, which is the defining criterion for the competitiveness of machinery and technology at the industry’s present stage of development. The purpose of the research was to study milk production technology based on a comprehensive assessment and implementation of modern milking equipment, maximizing animals’ genetic potential and industry efficiency. We proved that applying the ‘DeLaval’ milking parlor under the same feeding and keeping animals ensured the proper completeness of milking and increased cows’ milk yield. During the first, third, and highest lactations, the milk yield was 226 kg (P=0.05), 266 kg (P=0.05), and 214 kg (P=0.05), respectively. After-milking when applying ADM-8A averaged 175 ml, and only 45 ml when applying the ‘DeLaval’ parlor. When using the ‘DeLaval’ milking equipment, the milk production intensity of cows was 1.43 kg/min, and, with ADM-8A, it was 1.24 kg/min, which is 0.19 kg/min (P=0.001), or 15.3% higher.

Creating an optimal microclimate in poultry houses is an important condition for implementing the genetic potential of poultry productivity and minimizing the specific costs of material and technical resources. Such microclimate parameters as the content of harmful gases in the air of the poultry houses and its microbial contamination have a significant impact not only on the survival and productive parameters of the poultry, but also on the health of the staff, and the ventilation emissions from the poultry houses - on the environment. Therefore, the development of techniques and technological methods aimed at reducing the content of these ‘harmful factors’ in the air of the poultry houses is of paramount importance for modern poultry farming. The first experiments were carried out in two similar industrial poultry houses for egg laying hens, 18×96 m in size. Hens were kept in 4-tier Hellmann cage batteries with a belt removal system and integrated air ducts. The capacity of each poultry house was 47,280 laying hens. The purpose of the experiment was to study the influence of the device for the neutralization of microorganisms in the air of the poultry house and its mode of operation on the microbial contamination of the air of the poultry house and the productive parameters of the poultry. The poultry of the Lohmann Brown crossbreed was used. The next experiment was carried out in the same poultry houses as in the previous one. The purpose of the experiment was to study the effects of the application of the method of purifying the air of the poultry house from the ammonia in the scrubber on the contents of this gas in the air of the poultry house and the productive parameters of the poultry. The poultry of the Lohmann Brown crossbreed was used in the experiments. It was established that at application of a bactericidal device with 24 bactericidal tubes TUV-75 caused a decrease of microbial contamination of the air, which positively influenced the survival and productive parameters of the poultry. After 210 days of the productive period, the poultry’s survival in the experimental poultry house was higher by 0.8%; 1.3 pcs. of eggs more per one egg laying hen were obtained in this poultry house; and the egg mass was higher by 0.7 g than in the control poultry house. With the hens from the experimental poultry house, a greater bactericidal and lysozyme activity of the blood serum was observed than with the ones from the control poultry house at the age of 30 and 47 weeks. Some advantage of the poultry from the experimental poultry house was determined by the absolute mass of individual internal organs, but this advantage was not statistically probable. It was proved that in the cold season, the scrubber provided a decrease in the ammonia content in the air (when comparing the air before and after the scrubber) by 3.2-2.2 times, in the poultry house (when compared with the control) - by 2.1-1.5 times. It was established that in the experimental poultry house the poultry’s survival was greater by 0.7%, 1.6 pcs. or by 1.0% eggs more per one egg laying hen were obtained and egg mass was higher by 212 g, or by 2.1% than in the control poultry house.

Litter in the poultry house is a source of toxic gases (ammonia, hydrogen sulphide and carbon dioxide), dust, and is a favourable place for the life and reproduction of microorganisms and helminths. The number of these secretions in the poultry house depends on many factors: the sanitary status of the poultry house, the species, the age of the birds, the microclimate, the season, feeding conditions, and so on. The purpose of the research was to substantiate the rational construction and modes of operation of the device for the decontamination of microorganisms in the air of the poultry house on the basis of the use of sources of ultraviolet irradiation. The necessity of development and application techniques for cage batteries with a litter removal belt system which provide reduction of microbial contamination of air in poultry houses and the content of harmful gases in it have been substantiated. The device was developed and the effective mode of disinfection of the air of the poultry house in the collector air duct of the litter drying system based on the use of sources of ultraviolet irradiation was determined. The application of the bactericidal device made it possible to reduce microbial air contamination on the 1st day of accumulation of the litter during the cold season - by 2.6 times, in the transitional season - by 2.1 times; on 5th day, the accumulation of the litter decreased by 3.0 and 2.3 times, respectively. During the operation of the air irradiation system, the content of toxic gases in it decreased compared to the period when the air was not treated with the ultraviolet irradiation - ammonia by 19.7% and carbon dioxide by 5.9%. The absolute values of microbial air contamination in the poultry house and the toxic gas content in the transitional season were lower than in the cold season, due to the higher indoor air exchange and the increase of clean outside air in the proportion. The difference in microbial air contamination between the basic and the proposed variants in the cold and transitional seasons was statistically significant.
