The article presents data on changes in the protein content of bee pollen due to different storage methods. In May, during the collection of bee pollen by bee colonies, in the conditions of the farm located in the Stryi district of the Lviv region, more than 30 types of flower pollen entered the nest. At the same time, for species identification, acetolysis of seven types of flower pollen was carried out, which differed in the maximum amount of arrival: apple (Malus), dandelion (Taráxacum), winter rape (Brassica napus), buckwheat (Fagopyrum esculentum), clover (Trifolium pratense), chestnut (Castánea) and raspberry (Rúbus idáeus). To study the nitrogen content according to the Kjeldahl method, all pollen was divided into three groups according to the storage method. Bee pollen of the first group was considered fresh. In it, the nitrogen content was determined immediately after determining the species. Calculations showed the maximum crude protein content in this group. Of all types of bee pollen that were determined to be fresh, the maximum amount of protein was found in bee pollen collected during the flowering of winter rape (Brassica napus) and apple (Malus). Its average content is 24.9 ± 2.09 and 23.4 ± 1.77 %, respectively. As a result of freezing at a temperature of 18 ºС and its storage for 8–12 months, the protein content practically did not change and decreased by only 0.3–0.9 %. A slight tendency to decrease the amount of nitrogen in bee honey was also found when stored in a dried state. Bee pollen, stored for 8–12 months under different conditions, was fed to newborn honey bees and kept in entomological boxes. It was found that bee pollen storage conditions affect honey bees' food consumption rate. The minor attractiveness of the feed was found in the dried bee pollen. The absence of a connection between the content of crude protein in feed and the rate of its consumption by bees was investigated.

The article, a comparative analysis of the productivity of piglets during rearing under a liquid feeding system with fodder mixtures, which were mixed in the feed containers of the Hydro Mix Pro feeding system of the Big Dutchmen company and with the help of the portioned feeding system Spotmix II of the Austrian company Schauer, is made. It was found that the preparation and distribution of feed using the Spotmix II portioned feeding system resulted in 1.5 % better piglet survival, 9.6 % higher piglet growth rate during rearing, 9.5 % higher absolute gains during this period, higher by 7.3 % of the weight of animals when transferred to fattening compared to analogs that were raised on liquid feeding with feed mixing in feed tanks. It has been proven that piglets that were prepared, transported, and distributed feed using the Spotmix II system consumed 6.0 % more feed per day, consumed 7.0 % more during the period, the cost of which was 10.6 % higher. Meanwhile, their feed conversion was 2.3 % better, with almost the exact feed cost per kilogram gain. The feeding of piglets in growing-out using the Spotmix II portioned liquid feeding system led to a 10.6 % higher cost of feed, a 22.1 % higher amortization costs for the equipment for feed distribution and animal feeding, a 9.6 % higher cost of the growing-out process of one pig, and its cost price at the end of the growing period is 3.4 times higher. At the same time, such feeding contributed to higher growth energy of animals during rearing, which caused a 7.3 % higher sales price of piglets, a 17.3 % higher profit from the sale of one head, and a 5.2 % higher profitability of rearing piglets compared to liquid feeding using Hydro Mix Pro system with feed mixing in feed tanks.

Nutrition is probably one of the main factors affecting a dog's health and general well-being. Its growth, development, mood and mobility depend directly on what food we feed our pet. In today's conditions, the issues of feeding, maintenance, upbringing, training, prevention of infectious diseases were and are quite relevant in the field of dog breeding. There is a very large number of especially foreign scientists who conduct research in this field of science. In Ukraine, scientists, in our opinion, pay little attention to the study and improvement of dog feeding techniques and rations in various directions of their use. The intensity of growth and development of the young, and the health of the dog mainly depends not only on maintenance and care, but also on correct and balanced feeding. Therefore, it is extremely necessary to have a full-fledged feeding, which involves ensuring the ratio of energy, nutrients and biologically active substances: proteins, fats, carbohydrates, vitamins, and minerals. The following principles of correct and reasonable feeding of dogs can be distinguished: ensuring the needs of animal organisms with the required volume and energy of fodder; and all nutrients; good palatability of fodder, technique and mode of feeding; the availability of nutrients for digestion and the chemical composition of feed and its safety. The principles of dog feeding and nutrition continue to develop intensively. One of the examples of how far scientists have advanced in this matter can be dogs, which half a century ago veterinarians considered purely carnivores. These dogs came to the clinics sick, thin, weak, with a metabolic disorder, which was a direct result of eating an all-meat diet. Most at that time thought that since dogs are carnivores, a meat diet and feeding should be the best for them. But in reality, dogs are omnivores. And so now we all know that feeding them rations consisting of 100 % meat for a long time can lead to irreparable consequences. In this article, we will try to consider different types and methods of feeding dogs, we will study the peculiarities of digestion of food in the gastrointestinal tract, which can help in the future to make the right choice of products or feed. Let's try to find out what is better to feed and what absolutely cannot be given to a pet, as well as what to do if he develops an eating disorder. Thus, we will make a detailed description of animal feeding in various cases, and help you form your own opinion on this issue in order to do everything correctly and not harm your pet.

We studied the possibility of fortification of goslings’ products with lithium and peculiarities of its depositing in the organs and tissues of goslings concerning lithium level in the mixed feed. Experimental studies have been conducted on goose breed Legart. A total of 320 one-day-old goslings were divided on the principle of analogues into four groups and 80 heads each. The goslings of the first control group did not receive the lithium supplement with the feed mix. Experimental groups were fed with the feed mixed that additionally was supplemented with different doses of lithium by the scheme of the experiment. After 70 days of rearing, three birds were randomly selected from each group and their control slaughter. The lithium content in the representative samples of muscle tissue and organs of goslings was determined by inductively coupled plasma-atomic emission spectrometry (ICP-AES). It was established that feeding the growing goslings with mixed feed containing lithium supplements in doses of 0.05, 0.1 and 0.15 mg/kg, contributed to the increase (P < 0.001) of the concentration of this trace element in the muscles of the thigh and drumstick accordingly 789.5, 1589.5 and at 3447.4 %, in the muscles of the breast 1096.8, 2080.6 and at 3948.4 %, liver are 455.4, 824.6 and at 1440.8 % are compared to goslings that did not receive lithium supplements. Significantly high values of lithium accumulation factors in organs and tissues of gosling (3.21–14.44) indicated that this element has a substantial accumulating capacity. The meat of goslings enriched with lithium can be considered as a natural product with bio-corrective action that can be used in human nutrition. These meat products can be particularly useful for people that are living in regions with a low environmental level of lithium.

Based on the center of hippotherapy "Berehynia Polissia" (Zhytomyr, Ukraine), a study was conducted on the preparation and organization of feeding of Hutsul horses used in hippotherapy to prepare children with psychoneurological disorders for an inclusive educational process. The analysis of animal feeding systems was developed and carried out, and the leading indicators of the growth and development of horses were determined using generally accepted zootechnical methods. The data obtained were processed using the methods of mathematical statistics. The determined values of the indices of the body structure of horses corresponded to the characteristics of the Hutsul breed. The physiological parameters of the animals allowed for convenient interaction and practical therapeutic sessions with children. The organized feeding provided for feeding the animals in sufficient quantities of feed with high biological value, which is necessary to meet the needs of the horses for energy, organic, mineral, and biologically active substances. In the structure of winter rations, roughage accounted for 67.3 %, root crops for 6.5 %, and concentrates for 26.2 %. In the summer rations, the share of roughage ranged from 57.3 to 61.7 %, fodder beet – about 6.1 %, and concentrated feed – from 24.43–25.78 %. The premix was fed within 1% of the total nutritional value. The daily salt content in the horses' diets ranged from 30 to 40 g. It was found that the consumption of an appropriate amount of metabolic energy, organic matter, and mineral elements by horses during active exercise helps to maintain their condition at a level of average fatness. The horses demonstrated a therapeutic effect, confirmed by an experimental study. In particular, 83.3 % of children with neuropsychiatric disorders had an average level of adaptation to the inclusive educational process, 10.4 % had a high level, and 6.3 % had a low level.

The intensive use of boars and receiving biologically complete valuable ejaculates from them is possible due to early assessment of the quality of sperm production and timely determination of their genetic potential. The research aimed to determine the peculiarities of the formation of sperm production and the course of peroxide oxidation in boars during puberty. For the experiment, 5–10 month-old boars of Poltava Meat, the Large White, and Myrhorod breeds were used. The quality of the obtained ejaculates was evaluated according to standard indicators according to the instructions for artificial insemination of pigs. The research results indicate a significant increase in the quantitative indexes of sperm production in young boars in the age range with different features for each breed. By the eighth month of life, a general tendency to increase the parameters in the received ejaculates is noted. In contrast, the highest increase in ejaculate volume and sperm concentration was found in young boars of the sebaceous direction of productivity on the 240th day of the development (4.6 and 1.9 times). The minimum motility and survival of gametes were observed at five months, regardless of the breed, with a gradual increase to maximum values at the seventh and eighth months of age, depending on the direction of animal productivity. The use of moderate sexual load for young boars after they reach the age of 9 months ensures the functional activity of sperm suitable for artificial insemination (motility above 80 % and survival above 70 %). The significant changes in the pro-oxidant-antioxidant homeostasis in the sperm of boars of 7–8 months occur in the direction of the acceleration of the peroxygen oxidation of lipids, which is evidenced by an increase in the content of diene conjugates and TBC-active compounds and an increase in the activity of enzymes of the antioxidant link. An earlier formation of pro-oxidant-antioxidant homeostasis in this secretion is noted in representatives of the meat and fat direction of productivity. Thus, the obtained results indicate significant age-related changes in the ejaculate parameters and peculiarities of the course of peroxide oxidation processes depending on the breed of boars.

When breeding dairy cattle, productivity is of the greatest economic and economic importance. A sufficient number of highly productive animals and their effective use in herds reveals the breed's potential, contributes to increasing the genetic potential of cows and the effectiveness of selection and breeding work as a whole. At the same time, it should be noted that according to many scientists, fathers of cows have the most significant influence on the formation of signs of milk productivity. In dairy cattle breeding, about 90 % of the genetic progress of the population is provided by bulls. However, the research of different farms shows that bulls do not have the same effect on the productivity of their daughters. Therefore, it must be taken into account when planning work on improving the productive qualities of dairy cattle. In view of the above, the goal of our research was to find out the influence of bulls on the formation of milk productivity of daughters in different farms. The research was carried out in farms located in different climatic zones of Ukraine, namely: in the SE EF “Olexandrivske” in Vinnytsia region (Forest Steppe zone, n = 714), LLC AE “Imeni Volovikova” in Rivne region (Polyssia zone, n = 1840) and SE “Experimental farm “Askaniyske” (Steppe zone, n = 926) on first-calf heifers and adult cows (III lactation) of the Ukrainian Black-and-White dairy breed. It was established that during the first lactation, the highest milk yield and milk fat output in the SE Oleksandrivske were characterized by the daughters of the bull Dzhorin (6936 and 248.9 kg), during the third – the daughters of the bull Detektiv (8148 and 295.2 kg), and the most fat-milk the above lactations were, respectively, daughters of Zhames (3.68 %) and S. Aristotl (3.63 %). In LLC AE “Imeni of Volovikova” the daughters of the bull R. Baltimor (7509 and 7486 kg and 267.8 and 281.9 kg, respectively) had the highest milk yield and milk fat output for the two studied lactations, daughters of Derbi (3.74 %) for the first lactation had the best indicators of fat content in the milk, for the third – daughters of Tirs (3.64 %). In the SE "Experimental Farming “Askaniyske” first-calf heifers – daughters of N. Bolt were the most productive (7348 kg), in terms of milk fat output - daughters of Surguch (292.2 kg), and in terms of milk fat – daughters of Latur (4.31 %). The highest productivity during the third lactation was observed in the daughters of the bull Akord (8,329 kg of milk fat, 320.8 kg of milk fat), and the highest milk fat content was observed in the daughters of Polarshtern (4.37 %). The influence of bulls on the fertility of cows in controlled farms was in the range of 14.9–46.2 %, on the fat content in milk - in the range of 7.4–20.2 %.

A sufficient number of highly productive animals and their effective use in herds reveals the breed's potential, contributes to increasing the genetic potential of cows and the effectiveness of selection and breeding work as a whole. At the same time, it should be noted that according to many scientists, fathers of cows have the most significant influence on the formation of signs of milk productivity. In dairy cattle breeding, about 90 % of the genetic progress of the population is provided by bulls. However, the research of different farms shows that bulls do not have the same effect on the productivity of their daughters. Therefore, it must be taken into account when planning work on improving the productive qualities of dairy cattle. In view of the above, the goal of our research was to find out the influence of bulls on the formation of milk productivity of daughters in different farms. The research was carried out in farms located in different climatic zones of Ukraine, namely: in the SE EF “Olexandrivske” in Vinnytsia region (Forest Steppe zone, n = 714), LLC AE “Imeni Volovikova” in Rivne region (Polyssia zone, n = 1840) and SE “Experimental farm “Askaniyske” (Steppe zone, n = 926) on first-calf heifers and adult cows (III lactation) of the Ukrainian Black-and-White dairy breed. It was established that during the first lactation, the highest milk yield and milk fat output in the SE Oleksandrivske were characterized by the daughters of the bull Dzhorin (6936 and 248.9 kg), during the third – the daughters of the bull Detektiv (8148 and 295.2 kg), and the most fat-milk the above lactations were, respectively, daughters of Zhames (3.68 %) and S. Aristotl (3.63 %). In LLC AE “Imeni of Volovikova” the daughters of the bull R. Baltimor (7509 and 7486 kg and 267.8 and 281.9 kg, respectively) had the highest milk yield and milk fat output for the two studied lactations, daughters of Derbi (3.74 %) for the first lactation had the best indicators of fat content in the milk, for the third – daughters of Tirs (3.64 %). In the SE \"Experimental Farming “Askaniyske” first-calf heifers – daughters of N.

The results of the production approval fully confirmed the high efficiency of introducing the feed additive “Butaselmevit-plus” into the compound feed for piglets. It was established that at the end of the piglet rearing period (at the age of 75 days), the average weight of one head in the experimental group was 32.6 kg, which is 1.1 kilograms or 3.5% higher (P < 0.05). Then their peers from the control group. During the period of rearing, the absolute increase in body weight in young animals of the experimental group was higher by 1.2 kg, or by 4.7 %, and the average daily weight gain by 21.8 g, or by 4.7 %, compared to similar indicators in piglets of the control group, and were 26.5 kg and 481.8 g, respectively. Among the numerous indicators determining the economic efficiency of production, the cost per unit of production is considered the most important. One of the reserves for reducing the cost of pig production is increasing young animals' productivity and preservation. The above results of the production inspection convincingly prove that using the feed additive “Butaselmevit-plus” in compound feed for piglets at the rate of 100 mg/kg of body weight increases their product qualities and, as a result, improves economic indicators. In the experimental group, the cost of 1 kg of live weight of piglets during rearing decreased by UAH 0.57, or 3.0 %, compared to the young of the control group and amounted to UAH 18.25. The cost of 1 kg of live weight gain in control and experimental groups was slightly higher (23.44 and 22.46 UAH, respectively), and the difference in favor of the latter was 4.2 %. The decrease in the unit cost of production in the experimental group was due to the increase in body weight and the survival of young pigs during the rearing period. The economic effect of using the feed additive “Butaselmevit-plus” as part of compound feed, calculated per 1 head of young pigs, was UAH 25.97 at the prices set for feed and feed additive in 2019. To increase the adaptability of piglets at an early age when weaning from the sow and to prevent the development of oxidative stress, for further maintenance during the period of rearing and fattening, it is recommended to use the feed additive “Butaselmevit-plus” in the amount of 100 mg/kg of body weight per day together with concentrates diet in the period from 21 to 40 days of age.

In today's conditions, the issues of feeding, maintenance, upbringing, training, and prevention of infectious diseases were and are relevant in dog breeding. Many primarily foreign scientists conduct research in this field of science. However, scientists in Ukraine do not pay enough attention to the study and improvement of the technology for feeding and keeping dogs in kennels of departmental institutions, mainly where dogs are used to help people and serve. A dog is a man's best friend, reliable assistant, and faithful companion. Even in ancient times, a person tamed a dog and adapted it to perform various tasks. People use sled dogs to move over challenging terrain and transport various cargo. Guard dogs protect herds of livestock, protect them from predators, and protect critical economic facilities and human housing. Service dogs successfully serve on the border, help to detain criminals, search for drugs and explosive devices, perform the duties of signalmen and paramedics, rescue drowning people, and search for victims in the rubble after an earthquake and swept away by snow avalanches in the mountains. Hunting dogs of all breeds help hunters search for and catch wild animals or birds, making hunting interesting and exciting. The article assesses the technique of feeding dogs in the “Home of Rescued Animals” BF conditions. The reported data shows that the number and breed composition of dogs has been gradually increasing over the past year, and by the beginning of 2023, it will be 84 dogs. The basis of the diet for dogs is the food of animal origin (offal, meat, milk, and dairy products, animal fat), plant origin (oat groats, barley, millet, vegetables), sea fish or seafood, mineral additives (bone meal, table salt ), vitamin preparations (Tetravit, Catozal). In the conditions of the BF “Home of Rescued Animals”, dogs are fed twice a day – in the morning and the evening, approximately 1.5 hours before the walk and 30–60 minutes after the walk. Feeding dogs depends on the daily routine–drinking all dogs without restrictions. The blood test results prove that all physiological processes in the animal's body commonly occur without deviations. In current conditions, the basis of a dog's health, longevity, and good physical condition is a complete and balanced diet. The type of feeding should meet the needs of the dog's body and differ depending on the stage of the life cycle (young growth period, sexually mature dog, animal in the aging period) and the characteristics of physiological development (lack of various physical activities, increased physical activity, pregnancy and feeding puppies, etc.).
