Improvement of welfare of piglets is one of the key factors which underlie the effectiveness of producing pork and the profitability of pig farming. This article offers a solution to the main industrial problem – creation of comfortable maintenance conditions for pigs using toys which satisfy their ethological needs. Piglets used in the experiment were kept in the swine complex of agricultural production of Agrofirm Mig-Service-Agro Cooperative in Novoodesky district of Mykolaiv Oblast (Ukraine). The objective of the study was assessment of the effect of toys on the behaviour of piglets, level of concentration of hormone serotonin in blood plasma and their energy of growth. The experiment was performed on 120 weaned piglets aged 28 days, which were divided according to the principle of analogues with 60 individuals in each group: I – the control group, the animals were kept with no toys; II – the experimental group, where the animals had toys. During the experiment chronometric monitoring of the piglets’ behavioural acts was carried out using video observation, we extracted blood samples for determination of the content of the hormone serotonin using the method of highly-efficient fluid chromatography and assessed the growth of the piglets. After the end of the experiment, we determined that the presence of toys reduced the intragroup aggression, which was accompanied by decrease in the duration of fights and almost three-fold increase in playing behaviour. Among piglets which had access to toys, the number of individuals observed to bite tails and ears decreased from 11 to 3. In the period of the study, the concentration of serotonin in the blood plasma of piglets who had free access to toys was 10 times higher compared with animals of the control group. Change in the behaviour patterns among the animals of the experimental group led to significant differences regarding the parameters of growth, where probable increase in the live weight at the age of 90 days was observed, which was associated with significant increase in their mean daily weight gain compared with the animals of the control group. This study confirms that use of toys for piglets during growth completion can prevent features of aggression and abnormal forms of stereopathy within groups, increase the live weight and mean daily weight gain and improve emotional condition, which affects the welfare of pigs.

The research was conducted in 3 groups of rearing bulls aged 12–18 months, with an average initial live weight of 363–367 kg. The amount of non-degradable protein in diet of rearing bulls of the control group was lower by 10 % of the accepted standard. The second experimental group corresponded to the accepted standard due to extruded peas, lupine and flax meal.The level of non-degradable protein in III experimental group was above the standard by 10 %. The research helped to determine that experimental groups of bulls that consumed food with the level of non-degradable protein according to the standard and 10 % higher in the rumen contenthas an increased level of total nitrogen by 5.1 % and 5.5 % and protein – by 7.5 and 8.2 % respectively. A significant reduction in the amount of ammonia in the rumen of experimental animals was determined by 21 (P<0.05) and 24.0 % (P<0.05), respectively, which indicates the decrease in protein degradability and improvement of its use by microorganisms for protein synthesis. Animals of II and III experimental groups consuming food with higher levels of non-degradable protein digested feed nutrients better. Thus, digestibility of dry and organic substances and protein significantly increased by 6.4 and 6.9; 6.4 and 7.1; 5.6 and 5.5 %. There is a tendency to increase of digestibility of fat, fiber and BEV. As a result of the analysis of the morphological and biochemical composition of blood, it was determined that there were no significant differences in all of the studied parameters, they all ranged within the physiological standard. However, there was an increase of total protein by 4.0 %, total and protein nitrogen – by 4.0–5.0 % in bulls’ blood of the II experimental group, while in young animals of III experimental group these indicators increased respectively by 6.5 and 7.0 %. The research has shown that the average daily weight gain of the bulls in control group was 980 g, and in the experimental ones it increased to 1009–1029 g or by 3.0 and 5.0 %. As for the volume of ejaculate, bulls of II and III groups surpassed their coevals of group I by 11.0–14.0 %, and by semen concentrations – by 9.0–12.0 %. The energy in weight gain of bulls of II and III experimental groups ranged 19.9–20.8 MJ, or 4.1–9.0 % and was higher compared to group I. The transformation of metabolizable energy of diet into body weight gain increased from 21.6 % (control) to 22.4– 22.6 %. The energy spent on diet per 1 MJ for weight gain decreased from 4.6 MJ (control) to 4.4–4.5 MJ or by 4.0–5.0 %. However, the best results were observed in young animals of III experimental group, who received diets with the level of non-degradable protein in the amount of 10 % above the standard. Key words: calves, diet, feed, degradable protein, non-degradable protein, rumen digestion, performance.

The aim of the study was to find out the effect of casting of citrate nanosіlicon absorption and metasilicate sodium on the hematological parameters and lipid content and their fractional composition in blood plasma preparatory period 10 days prior to insemination and 20 days of lactation. The research was carried out on 60 rabbits of the Hyla hybrid, divided into three groups (control and two experimental), with 20 animals in each. The control animals were fed without limitation full-grain granulated feed with free access to water. Animals of the first experimental group (E-I) fed the diet of the control group and during the course of the day poured out the silicon citrate obtained using the nanotechnology method, 50 mkg Si/kg body weight with water. Samples of the second experimental group (E-II) feed the diet of the control group and set the sodium metasilicate (Na2SiO3H2O) 2.5 mg Si/kg body weight with water. The trial lasted 95 days, including the preparatory period of 10 days, the trial – 85 days. In the preparatory period of 10 days from the beginning of the study and in a trial of 20 days of lactation (65 days of supplements) in the rabbits, samples of blood from the marginal ear vein were taken. Hematologic studies were performed using the automatic hematologic analyzer “Orphee Mythic 18”, in the blood plasma, the content of total lipids and their fractional composition were determined. It was established that the number of erythrocytes and hemoglobin concentration in the blood of the rabbits of experimental group, which were given silicon citrate, were respectively higher by 15.2% (P < 0.05) and 12.0% (P < 0.01) by 20 days lactation versus control. This may indicate a more pronounced effect of the organic compound of silicon on the hematopoietic function of the body of the rabbits. According to white blood, the differences from control were found during the presentation of supplements with higher (P < 0.05) changes in 20 days of lactation in animal blood and experimental group. It was noted that the content of triacylglycerols in plasma of blood of groups I and II was lower by 31.2 and 32.8%, respectively (P < 0.05) compared to control. In blood plasma of animals in experimental groups an increase in the fractions of phosphatidylcholine, sphingomyelin and lysolecetin was observed compared to control. Such a redistribution was due to the reduction of the fractions of phosphatidic acid, phosphatidyl ethanolamine and phosphatidylinositol, and apparently, is associated with changes in the activity of the enzymes concerned. Hematological studies and determination of the fractional composition of lipids and phospholipids of blood plasma of the rabbits show positive changes that contribute to the metabolic accumulation of energy and plastic components of their organism.

The scientific results of the body weight dynamics, the multiplicity of its increase, the average daily weight gain, the relative growth rate and the exterior indicators are presented. The brewers waste is a high-protein product with a high content of carbohydrates, including fiber.For the research, three groups of Jersey breed were formed on the principle of the analogue group: the first was control, the second and the third – experimental. Their rations were introduced by 15 % and 20 % of dry brewers waste from the total diet, respectively. It was established that the live weight of the experimental cows from the 2nd group was 9.3 times bigger. The live weight of the experimental cows from the 1st and 3rd group increased 9 times. The cows from the 2nd group had the highest average daily weight gain (811.4 g) in the period from 2 to 6 months. It was 3.2 % times more than in the control group and 7.4 % times more than in the 3rd experimental group. The cows from the 2nd experimental group had the highest relative growth rate (85.7 %) in the period from 2 to 6 months which was 2.2 % times more than in the 1st control group and 4.2% times more than in the 3rd experimental group. In the period from 6 to 12 months, the 2nd experimental group had the highest average daily weight gain (671.4 g), which was 2.1 % more than in the 1st control group and 3.5 % more than in the 3rd experimental group. From 6 to 12 months the relative growth rate in all groups was almost the same and ranged from 54.2% – 54.7 %. At the age of 12 months, the 1st control group had greater index (120.4).

The effect of Phytoplus on weaned piglets was studied for the period of 50 days in 2018 and the influence of Algasol preparation on pregnant sows was investigated during 60 days in 2017. Phytoplus contains extracts from Rhaponticum carthamoides, Serratula coronate, and Filipendula ulmaria plants. It was administered daily, against the background of the control, into the diet of piglets aged from 40 to 90 days (n = 50 in the group): group No. 1 ‒ 0.3 g; group No. 2 ‒ 0.5 g; group No. 3 ‒ 1 gram per head per day. When Phytoplus was used, livability of piglets in all groups was 100%, the incidence in the experimental groups (2.3±0.3 heads) was 1.6-2.5 times lower than in the control group (5 heads). The live weight in the experimental groups (48,3±5,9 ‒ 51,4±7,5 кг) exceeded the result in the control group (41.8 kg) by 15-22%, and the intensity of the average daily weight gain by 24-33% (764,0±3,0 g ‒ 818,0±4,3 g against 616±2,2 g). Significant difference (P <0.05) was observed in piglets of the 3rd group, where AST increased, as compared with the beginning of the experiment, by 21.3% (from 15.9±0.6 to 19.3±0.5 units / l), and ALT by 12% (from 23.3±1.1 to 26.1 ± 2.1 units / l) and in the 2nd group where ALT increased by 46% (from 17.7±1.3 to 23.9±1.3 units /l). Algasol is a preparation from the extracts of brown algae and licorice roots. The experiment was carried out on nursing sows of large white breed pigs (2 groups of 48 animals each) when farrowing and before weaning piglets at 28 days of age. Sows of the experimental group were given Algasol daily at a dose of 50 ml per head. Algasol optimized their overall condition. The sows of the experimental group yielded 2% (572 pigs) more than in the control (561 pigs), the stillbirth decreased by 8% (23 vs. 25 animals). The death rate in the experiment was 2.1 times lower than in the control (17 vs. 8 goals), and livability was 98.5%. It has been established that Phytoplus and Algasol exert influence on the adaptive-compensatory reactions in the body of piglets and sows, that is proved by an increase in weight gain, livability of the young, and rise in the milk yield of the sows.

The purposes of determining the influence of the light and sexing on growth performance and slaughter results atyoung quails from Balotesti population, was organized an experiment on 150 quails, betwen age of 28 and 70 days. The chicks were divided into two groups (control and experimental), and growth and slaughter performance were determined separately by sex. Have studied 2 lighting programs, a program of continous lighting with photoperiod duration of 16 hours (16 L + 8 N, control group) and a program with lighting with asymetric hours intervals with photoperiod duration of 16 hours (10L+2N+6L+6N, experimental group).Males and females from the experimental group were recorded average performance of growth high during the period 28 - 70 days. Live weight at age of 70 days was higher with 7.54 %, average weight gain was higher with 14.86 % and feed conversion rate was lower with 13.51 % at males from experimental group compared to males from the control group. Also, the live weight at the age of 70 days was higher with 18.09 %; average weight gain was higher with 35.12 %, while feed conversion rate was reduced with 30.08 % on females from the experimental group compared to females from the control group.The results of the slaughter at 70 days were superior in the caseof females from the both groups versus males. The average weight of the carcase was higher with 17.53 % in case of the females than that of males from the experimental group, and the carcase yield was 65.37 % at the females and 65.56 % for males. Also, the average weight of the carcase was higher with 5.08 % in case of females compared to that males from the control group, and the carcase yield was 64.20 % to females 66.70 % on males.Superior results recorded in the case of females and males from the experimental group recommended the program of lighting with asymmetric hours intervals in the growth of youth quail. Also, the higher slaughter results recorded in the case of females of the two groups recommended them in the meat production through a broiler of quail that combine advantages in the production of both males and females.

The protein, vitamin and mineral supplements have been developed and it was studied the efficiency of feeding with them the young cattle in the composition of the grain production. The scientific and farm experiment has been carried out during 62 days. The study was conducted in four groups of bulls with 12 heads in each. The initial live weight at the beginning of the study was about 300–310 kg. Differences in feeding were in the fact that the grain forage for young animals of group I included PVMS No. 1, II – PVMS No. 2, III –PVMS No.3, IV – PVMS No 4. The grain feed is represented mainly by barley. The protein, vitamin and mineral supplement replenished 20 % of the deficient protein. It was discovered that concentration of hydrogen ions was practically at the same level in the rumen contents of steers of different groups. As for level of ammonia, VFA, total nitrogen, ciliates in the young cattle of I, II and III groups, the differences were insignificant. The concentration of ammonia of group IVcompared to I, II and III group was higher by 15.58, 23.61 and 21.9 %, VFA – by 6.7, 19.4 and 11.1 %, total nitrogen – by 3.32, 31.44 and 24.03 %, ciliates – by 4.35, 14.29 and 9.09 %, respectively. The research results showed that digestibility of protein, fiber and BEV was higher in the fourth group by 1–7 % compared with the rest groups (P>0.05). A slight increase in nitrogen deposition was found in IV group of young animals (by 4.7–11.9 %) receiving PVMS with AFA as a source of protein. The use of calcium and phosphorus by animals was almost at the same level. The research helped to determine that the average daily weight gain of animals of all the groups was within the range 629–710 g. The highest was in the fourth group consuming PVMS No. 4 with AFA as a protein component; the second place in terms is occupied by group I – 660 g, consuming PVMS No. 2, which included lupine, AFA and standard DKMK No. 1; PVMS No. 3 with depleted phosphate used as a source of phosphorus, took the last place in terms of this indicator – 629 g. Feed cost per 1 kg of weight gain was the lowest in IV group – 8.77 feed units, in I, II and III groups, it was higher by 8.32 %; 13.68 and 10.83 %, respectively. The cost of sold products from one animal during experiment turned out to be higher for steers that received PVMS No. 4 as compared to I, II and III groups by 6.82, 11.36 and 9.1 %, respectively.

Study was carried out on the basis of PC Haleks-Agro. It is located in the village Gul'sk of Novograd Volynskiy district of Zhytomyr region. In the farm to bred of Simmental cows. For the experiment was formed four groups. We took into account age, live weight of 650–700 kg and the average milk yield 5000–6000 kg. Animals is located in identical conditions of feeding and maintenance. Research experiment was carried out on animals couples counterparts.  Preparations introduced animals three times at 10–12 days after insemination. The cows first experimental group were injected complex nanokarboksylativ Ge, Cu, Mn and Cr, second – drug Kvatronan–Se and animals third experimental group was administered a complex composed of Se, Cu, Mn, Cr. On 13 day after insemination in experimental animals were taken blood from tail vein and examined the contents of hematological parameters. Established that injection nanokarboksylativ enhance the fertility of cows in the first and third group, the figure rose to 20% in the second by 40% compared with the control. Research hematological parameters blood  animals shows that after entering content drugs of blood cells had minor changes but remained within the physiological norm. The results show that in  concentration monocyte the second group  was at 5.53% (P > 0.01) higher compared to the control group and 2.3% compared to the first and third. The content of lymphocytes in this group decreased by 26.3% (P > 0.05), 22% and 16% relative to the control, the first and third groups. Also, it should be noted that the hemoglobin in the experimental groups decreased in group I by 7.9% in the II – 3.9% and III by 7.3% compared with the control group. Also, these groups distinguished downward trend eosinophils 1.8%, 1.5%, 2.05%.

The purpose of the research is increasing the average daily gain of animals due to the use of the Bisolbi drug. The effect of Bisolbi preparation based on Bacillus subtilis H-13 1.5×108 (LLC «Bisolbi-Inter») on the biochemical and productive life of calves was studied. The scientific and production experiment was carried out on the basis of a dairy farm of the State «Kupinskoe» Unitary Enterprise of the Samara region involving 30 Holstein-Friesian calves. The biological effect of the drug is provided due to its adsorption properties, the ability to enhance the activity of a number of enzyme systems and increase the digestive and systemic immunity of the body. The drug use increases the integration intensity of animals: the amount of total protein in the blood serum of calves of the experimental group at 120 days of age was higher by 8.9% (p<0.05), albumin – by 9.2% (p<0.01), compared with the animal data of con-trolled group. The Bisolbi indication contributed to an increase in the intensity of carbohydrate-lipoid metabolism: the cholesterol amount was higher by 23% (p<0.01), the glucose content – by 0.4 mmol/l (p<0.05) in the blood of 120 day old calves of the experimental group, compared with the data of controlled animals. It was found that the body weight of calves in the control group of 100 days age was 105.23±2.11 kg, in the experimental group – 108.6±2.19 kg, which is 3.37 kg higher. The average daily weight gain of animals in experimental group was signif-icantly higher by 0.075 kg (p<0.01). At 120 days of age, the body weight of the experimental calves was higher by 4.19 kg (p<0.05), the average daily weight gain by 0.080 kg (p<0.05), compared with the data of the controlled ani-mals. The indication of Bisolbi 5-10 ml (LLC «Bisolbi-Inter») to calves daily for 2 months resulted in an additional profit constructively of 137 rubles from each head.

The application of oxytocin induction to milk production in relation to the performance of kids in dairy goats had been carried out in the "PEGUMAS" dairy goat farmer group Gumelar District, Banyumas. This activity aimed to increase milk production and kid performance through the induction of the hormone oxytocin in dairy goats. The approach method was designed in two stages: the first stage carried out the socialization activities and demonstration of techniques for applying IPTEKS, and the second stage applied hormonal technology in the form of oxytocin hormone induction in dairy goats. The material used was dairy goat parity I aged 1.5 - 2 years allocated into 2 groups of 10 individuals each. Group I was dairy goat experiment not induced with the oxytocin hormone as the control. Group II was dairy goat experiment induced with the oxytocin hormone at a dose of 1 ml (10 IU) intramuscularly before milking. Milk production was measured morning and evening as daily milk production in milliliters (ml). Milk was given to the kid of each parent. The kid's performance was measured based on the daily weight gain of the kid during the study. Overall, the application of science and technology could be adopted by farmers, and oxytocin-induced dairy goat milk production (503.2 ml) was significantly higher (P<0.05) than control (305.4 ml) with an increase of 64.77%, with a positive level of correlation (r = 0.45) and contributed 19.83% to the kids daily body weight gain.

Aimed to study the effective use of different doses of cuprum proteinate in the diet of broiler chickens, three groups of animals were formed with 50 chicks in each. Chickens from the 1st control group received cuprum sulphate as a part of compound feed, and animals from the 2nd and 3rd experimental groups received cuprum proteinate. The concentration of Cuprum in the feed in the 1st and 2nd groups was identical, and in the 3rd experimental group the amount of Cuprum was reduced by 25% compared to the control. During scientific and economic experiment, it was found that the replacement of cuprum sulphate with its proteinate with the same concentration in the feed has a positive effect on the average daily gain of broiler chickens, and therefore a live weight. Thus, the animals from the 2nd experimental group exceeded control analogues by 7.5% in average daily gain and by 9.4% in body mass at the end of the experiment. Reducing the concentration of Cuprum in the feed of chickens from the 3rd experimental group by 25% (the source of the microelement is cuprum proteinate) compared to the control also had a positive effect on the productivity of these animals. They exceeded control analogues in terms of average daily weight gain by 3.8%, and in terms of live weight by 5.8%. At the same time the direct correlation between animal productivity and quantity of the consumed feed was noted. Thus, broilers from the 2nd experimental group consumed more feed by 3.3% compared to control peers. The chickens from the 3rd experimental group exceeded controls by 1.5% in this index. Thus, cuprum proteinate is a more efficient source of Cuprum for broiler feed. The concentration of this microelement in the feed of these animals aged 5-21 days should be 18.2 g/t, 22–35 days - 16.8 g/t, 36–42 days - 12 g/t or 16.5 g/t on average during the experiment.
