This article discusses the veterinary and sanitary examination of meat in the recovery of farms treated for chlamydia of cattle. The article examines the content of organoleptic, physico-chemical and residual amount of antibiotics in meat in chlamydia of cattle. According to the results of the study, the physical and chemical parameters of beef did not change when using antibiotics and did not affect the freshness of meat. Upon examination of the research on the surface thus in the experimental group and the control group showed signs of microbial bodies. In the surface layers of muscles from healthy animals thus the number of microbial bodies was normal. No microbial bodies were found in the deep layers of the muscles in the control and experimental groups. When determining the residual amount of antibiotics in meat, tetracycline antibiotics with high inhibitory activity against chlamydia were used. In our case, the antibiotics doxycycline 200 and nitox 200 were used. The residual amount of antibiotics in the meat samples of the tusch control group, where the antibiotic doxycycline 200 was used for 21 and 28 days after slaughter, was not detected in the meat samples. At the same time, in the group where the antibiotic nitox 200 was used on 21 days after slaughter, meat samples were found. And for 28 days after slaughter, the antibiotic was not detected in the samples of the control group and the experimental group. This means that the antibiotic doxycycline 200 is more effective than nitox 200 and is excreted from the animal body faster.

The goal of the work was to investigate the physical and chemical characteristics of the meat of broilers fed with mixtures in which fishmeal had been replaced with fresh earthworms and worm meal. The experiment was carried out on 100 day-old chickens of both sexes, Hybro provenance, divided into 4 groups, 25 broilers each. The experiment lasted for 42 days and had three phases: the first lasted for 3 weeks, the second 2 weeks and the third 1 week. The control group of broilers were fed with complete feed for chickens for fattening, of standard fiber and chemical composition, while I and II experimental groups were fed with mixture in which fishmeal had been replaced by worm meal in an amount of 50 and 100 %, and III experimental group obtained a mixture with no fishmeal, but fresh, chopped earthworms ad libitum instead, from the 1st day to the end of the experiment. At the end of the experiment, on the 42nd day, the broilers were transported to a slaughterhouse. After individual weighing they were slaughtered, and primary processing and cooling of the carcasses were performed. Then the carcasses were cut up to the main parts and the breast samples were taken for examining the physical and sensory properties of the meat. The results of the investigation have shown that there was no difference in physical properties (colour, pH) of the breast meat (p>0.05) among the experimental groups. The breast meat sample ranking has shown that the E-II group samples were rated as the most acceptable while the least acceptable were the meat samples of the control group as well as of the group fed with food in which fishmeal was completely replaced with fresh earthworms.

The article presents the results of the study of the physical and chemical parameters of water for different methods of feeding the commercial young blue fox. The research was carried out at a private brewery in the Khmelnytskyi Ds. on 500 moths of the main herd. Spraying the youngsters of the experimental group was carried out in a traditional way – fom combined drinking water, distribution of water was carried out daily manually. Animals of the experimental group were injected using an automated watering system. Water samples were taken from: a water pipe, from combined drinking water for an hour and 12 hours after hand delivery – in the control group, from self-steering racks for maintenance of fur animals – in the experimental group. An analysis of the dynamics of physical and chemical parameters of water (odor, color, turbidity, rigidity, active acidity, dry residue and chlorides) was carried out for different methods of watering, and compliance with their current norms for drinking water for farm animals was established. In the course of experimental studies, there were significant differences in the organoleptic parameters and water properties in the control group as compared to water samples. Thus, for manual distribution of water for 12 hour there was a deterioration of odor on 1.1 points, increase turbidity almost twice, decrease in acidity – by 1.06 units. The indicated indicators exceeded the maximum permissible norms. The reasons for violations of the quality of drinking water in the traditional way of drinking were: contact with feed mixes in combined drillers, the effect of abiotic and biotic factors, staining residues. In samples of water in the experimental group there were no significant deviations of physical and chemical indices: they were within the limits of permissible norms. Isolation of drinking water from the environment, dosing at the need of the animal proved to be the main advantages of the atomized method of drinking fur-bearing animals, which gives grounds to recommend it for introduction into production. Further scientific research will focus on the study of the microbiological characteristics of water for different ways of drinking fur-bearing animals and, in fact, blue fox. In addition, interesting from a practical point of view can be the study of productive indicators of commodity young animals of fur animals with different methods of watering. It should take into account not only the dynamics of animal growth, the quality of fur, the level of preservation, but also production costs, including changes in the structure of the cost of fur.

Abstract The aim of this study is to determine the effectiveness of disinfectant on the viability of eggs from three nematode species (Ascaris, Trichuris, Ankylostoma). It was conducted in a microcosm from June 2018 to June 2019. The wastewater scan was sampled using 5 L sterile containers, the sample was arranged in four replicas, three tests and one control. The test samples received three disinfectants (Moringa, calcium hypochlorite and Moringa associated with calcium hypochlorite) at varying concentrations. The physical and chemical parameters were measured before and after the application of each disinfectant. The samples were then observed under an optical microscope. The viability of the eggs was determined by incubating the Petri dish samples at 30 °C for 30 days. The analyses show that some physicochemical parameters can significantly influence the efficacy of disinfectant on the eggs. The calcium hypochlorite associated with Moringa at 0.6 g/L showed greater efficacy on reducing viability and inactivation of eggs with 100% efficacy yield rates on Ankylostoma and Trichuris trichiuria and 97% on Ascaris lumbricoides eggs; this efficacy is significantly different from that observed on samples treated with Moringa and simple calcium hypochlorite. Of the three parasites tested, A. lumbricoides showed greater resistance to the disinfectant.

Diurnal vertical migration of four genera of cladocerans, namely Diaphanosoma sp., Daphnia sp., Moina sp. and Bosmina sp., during March to December, 2007 showed that the number of Diaphanosoma sp. was 501 units/1 in the surface layers, 172 units/l in the middle layers and 190 units/l in the bottom layers. The yearly number of Daphnia sp. in surface, middle and bottom layerss was 362 units/l, 46 units/l and 189 units/l respectively. In surface, bottom and middle layers, the number of Moina sp. was 159, 71 and 32 units/l, respectively. Bosmina sp. was 78 units/l in surface, 31 units/l in the middle and 33 units/l in the bottom layers. The number of Diaphanosoma sp., Daphnia sp., Moina sp., Bosmina sp., were 455, 149, 259 and 358 units/l, respectively in the morning, 63, 176, 142, 43 units/l at noon and 107, 55, 28, 59 units/l, respectively in the evening. Throughout the study period the cladocerans were always abundant near the surface during morning and evening. Among the factors responsible for the diurnal movement of cadoceran, light played the most important factor. The relationship between the physico-chemical factors and the cladoceran occurrence in the pond was also explored.

The problem of complete mineral and vitamin nutrition in rabbit breeding is relevant today, despite new discoveries, and research in this direction continues both in Ukraine and around the world. The paper presents experimental data from the results of research to study the effect of different doses of vitamin and mineral supplement "Tekro" in the diets of young rabbits on their productivity, slaughter quality and biological value of rabbit meat. The obtained data of body growth, massometric indicators of carcasses and internal organs of rabbits of experimental groups after slaughter indicate a positive effect of vitamin-mineral supplement "Tekro" on the intensity of development of the body and individual internal organs, which contributes to increased metabolic processes and weight gain in animals research groups. Feeding vitamin and mineral supplements to rabbits of experimental groups of the New Zealand breed for 45 days contributed to a better transformation of feed nutrients into products. In rabbits of the 3rd experimental group, which together with basic ration were fed 3.5 % of the premix "Tekro" at 90 days of age, the highest rates of body weight were recorded, which differed by 8.89 % compared to the control group. In a set of indicators that characterize the nutritional value of rabbit meat, we studied sensory indicators that characterize the quality of rabbit meat: taste, color, pH, juiciness, moisture content, elasticity, aroma, "marbling", etc. It was found that in the appearance of carcasses and muscles in the control group, the samples scored 8.4 points. In the 3-rd and 4-th experimental groups, the number of points on this indicator was higher by 1.2 %. The difference was a trend. Examining the aroma of meat, it was found that in the control of this indicator, the samples scored 7.8 points. In meat samples from experimental groups 3 and 4, the aroma was more identical to natural, so the samples received 2.6 % higher scores. Samples from 3 experimental groups scored the most points in terms of taste. Compared with the control, the figure was higher by 3.6 %. Examining the juiciness of rabbit meat, it was found that samples obtained from carcasses 2 and 3 of the experimental group tended to increase this indicator. Summing up the data, it was found that the highest overall score was found in meat samples from 3 experimental groups. The difference with the control was within the trend and amounted to 2.4 %. Feeding rabbits vitamin and mineral supplements to rabbits helps to obtain good quality meat products with high culinary properties. No data were available to support the effect of vitamin and mineral supplements on compound feed on the synthesis of toxic substances in muscle tissue or the deterioration of rabbit meat. The biological value of muscle samples from rabbits of the 2-nd experimental group did not differ from the control data. The increase was only 0.11 %. It was found that the biological value of muscle tissue from animals of the 4th experimental group was greater than in the control. The difference was 2.6 % Meat obtained from rabbits of the 3rd experimental group, which were fed compound feed with a content of mineral-vitamin supplement "Tekro" 3.5 %, in biological value outweighed the control indicators. The difference was not significant and amounted to 4.1 %. The use of different doses of vitamin and mineral supplements in the feed of young rabbits did not lead to significant changes in the quality of raw hides and furs.

The main physical and chemical parameters of a new sorbent developed on the basis of the minerals of the Samara region: clays, peat and dolomite are considered. The particle size of the clay after grinding at the stage of preliminary preparation was less than 1 nm, which relates them to highly dispersed materials. A chemical analysis of the composition of the components showed a high content of silicon and aluminum oxides, which possess ion exchange properties, and also made it possible to assign clays to montmorillonite rocks. The modification of the sorbent was carried out by thermal method. The density of the finished sample was 1.8 g / cm3. The method of scanning electron microscopy showed that the structure of the finished sample belongs to spongy bodies. The method of IR spectrometry confirmed the presence of functional groups in the crystal lattice of the sorbent, which cause not only the physical, but also the ion exchange and chemical nature of sorption.

The experiment was aimed to prepare mango flavored soy milk based dahi (whole cow milk : soy milk=1:1). To remove the beany flavour of soybean as well as to add the mango flavour, mango juice were added at the rate of 0, 5, 10 and 15%. Data on physical and chemical parameters were recorded and analyzed. It was observed that smell and taste, body and consistency, color and appearance as well as total score were significantly increased (p<0.01) when 5% mango juice added to soy milk based dahi. These properties could further be increased significantly (p<0.01) by increasing the level up to 10% but increasing the level of mango juice up to 15% were significantly decreased (p<0.01) the physical properties. After chemical analysis, a significant increasing (p<0.05) in acidity, total solids and carbohydrate content but a significantly decresing (p<0.05) in fat and ash content of dahi were observed due to the addition of mango juice. Compilation of physico-chemical properties it was observed that addition of 10% mango juice prepared a high quality low cost mango flavored soy milk based dahi. Considering the shortage along with high price of milk we could transfer the techniques to the manufacturer to produce and market the mango flavored soy milk based dahi.

The purpose of the work was to increase the effectiveness of rearing of young animals and milk production by providing dairy cows with easily digestible sugars obtained from local grain raw materials. The research on the use of grain molasses produced from rye grain in a pilot unit in the Sharkansky RTP UZHK-1000 in feeding cattle of Kholmogorskaya breed under the environments of the Udmurt Republic has been carried out. The innovative small-sized treacle unit operating on the basis of the principle of cavitation technology is designed for the enzymatic cleavage of grain polysaccharides to a more accessible form of sugars for assimilation. It has been revealed that the feeding of grain molasses to young cattle in the amount of 3 kg/head/day had a positive effect on the increase in the average daily gain of live weight and the intensity of growth of animals. In the first-calf heifers in control group the age of achieving the first insemination was 14,7 months with the live weight of 374,6 kg, in the first-calf heifers in experimental group it was 13,8 months, while their live weight was 378,2 kg. The insemination index in the first-calfheifers of the control group was satisfactory and amounted to 2,0, and in the cows of the experimental group it was good – 1,6 (P ≥ 0,95). The maximum milk productivity of first-calf heifers for 305 days of lactation has been recorded in the cows of the experimental group, where grain molasses was used, and amounted to 7702,0 kg, which was more than in the control group by 157 kg or 2,1% (P ≥ 0,95). Milk from cows of the experimental group was the most suitable for the production of fermented milk products. The physical and chemical parameters of milk were also higher in the group in which grain molasses has been fed. The lowest consumption of milk for the production of 1 kg of cottage cheese was noted in the experimental group of cows 6,43 kg, the same trend has been observed in the production of cheese where the consumption was 8,7 kg.
