Under modern and intensive feeding livestock and poultry density has increased, and brought a deterioration of the farm environment. The livestock and their excrement generate harmful gases such as ammonia, etc. which restricted the sustainable development and improvement of production efficiency of animal husbandry. In this paper, a new kind of far infrared porous ceramics was prepared to activate the animal drinking water. The activated water and common water were then supplied to pigs, and the fresh pig feces of experimental group and control group were collected on a regular basis. The residual protein content in feces was tested by Kjeldahl nitrogen method to study the influence law of the porous ceramics on absorbing nitrogen element in animal feces. The results showed that compared with the control group, the protein content in the experimental group decreased on average by 39.2%. The activated drinking water was conducive to the absorption of nitrogen in pig feed. The clusters of water molecules became smaller under the action of the porous ceramics. Hence, they were easy to pass through the water protein channel on the cell membrane for speeding up the metabolism.

The article presents data on the long-term effect (nine months) of a silicon compound supplied with drinking water – nonahydrate sodium metasilicate (10 mg/l in terms of silicon), on CD68-positive macrophages in the liver and spleen of laboratory rats. Changes in the morphological characteristics of this cell population were found. There was a decrease in the average cell area (in the liver of the control group of rats, the average macrophage area was 179.23±5.94 microns2, and in the group receiving silicon with drinking water – 117.04±3.35 microns2; in the spleen-136.02±3.93 microns2 and 103.44±2.8 microns2, respectively). Macrophages in the liver preparations of the experimental group of rats had a fewer processes and a darker cytoplasmic membrane. The number of macrophages in the liver per unit area was comparable, for the control group of rats it was 18.78±1.24, and for the rats that received with water with the addition of silicon – 19.41±0.75 cells. CD68+ macrophages of the red splenic pulp in laboratory rats that received silicon also underwent the following morphological changes: they were located in a denser way and had fewer processes, while the number of macrophages per unit area was 73.7±2.3 for the control group, 91.6±5.0-for the experimental group, respectively. The distance between them did not change. There was a change in the intensity of CD68 expression on the surface of the cytoplasmic membrane and in the cytoplasm of liver and spleen macrophages. These changes can be interpreted as the adaptive ability of liver and spleen macrophages to silicon introduced with drinking water. Given the heterogeneity of the macrophage population in the liver and spleen, further studies using markers for different subpopulations of macrophages are needed to clarify their role in the response of tissues to silicon supplied with drinking water.

Highly Dispersed Particles

Preparations of highly dispersed particles of trace elements are increasingly used in animal husbandry. This is determined by their extraordinary biological properties such as the ability to penetrate into tissues and organs, a high surface area, and so on. One of the promising directions for using highly dispersed particles both in the post-embryonic and embryonic periods of animal development is the use of trace elements as sources. This is determined by the relatively lower toxicity, higher bioavailability of elements from preparations of highly dispersed particles, which reduces the load on the environment and allows you to produce products enriched with minerals. The purpose of the research was to study the effect of highly dispersed drugs on rumen digestion, the composition of the rumen microbiome, metabolism and productivity of young cattle. A comprehensive assessment of the use of highly dispersed SiO2 and FeCo preparations in cattle nutrition has been provided in the paper. The digestibility of feed, metabolism, and productivity of young cattle when feeding highly dispersed particles have been studied. An unusual fact of increasing bacterial biomass when using highly dispersed particles of silicon dioxide in animal feeding has been described. A method for increasing the digestibility of feed components by ruminants through the use of highly dispersed FeCo alloy particles has been proposed. As follows from the data obtained the use of highly dispersed particles allowed to increase the live weight of experimental young animals to 413 kg in the 1st experimental group and 416 kg in the 2nd experimental group, which was by 11 (P ≤ 0,01) and 14 kg (P ≤ 0,01) higher than the control indicator. As follows from the analysis of the data obtained, the profitability of rearing young animals in the 1st and 2nd experimental groups was by 2,4 and 2,2 % higher than the same indicator calculated for the control group.

We investigated the effects of fermented potato protein (FPP), supplied through drinking water, on growth performance of broiler chickens. A total of 288 male broiler chickens were divided into two groups: a control group and an experimental group supplemented with 0.01% FPP in drinking water. The FPP group had a significantly higher BWG and ADG (P less than 0.01) and significantly improved FCR (Pless than 0.05). The percentage of breast was significantly higher (P less than 0.05) in fermented potato protein (FPP) group. The FPP group had an increased villus height (P less than 0.05) in duodenum and jejunum. Expression of IGF-1 gene in the liver was significantly higher in the FPP group than in the control group (P less than 0.05), whereas GHR gene expression did not differ between the groups at 37 days. This study suggests that FPP supplementation in drinking water improves growth performance of broiler chickens by stimulating IGF-1 gene expression in the liver and improving the intestinal morphology.

The paper presents the results of an experiment on the use of enzyme-probiotic supplement “Immunobacterin-D” for calves in the first two months of life. Probiotics are used in animal husbandry for the prevention and treatment of infectious diseases, increase immunity, correction of the microflora after antibiotic therapy, prevention of stress, increase growth. The study was conducted in a private farm in the Lyubar district of Zhytomyr region, which kept cattle of different ages. In a randomized controlled trial, two experimental groups of six animals were formed in each on the principle of analogues. One group was a control. Calves of the experimental group from the second day after birth were fed together with colostrum “Immunobacterin-D” at the rate of 3 grams per animal. For the first five days, the enzyme-probiotic supplement was given to the calves once a day during the morning feeding, and in subsequent studies, once every two days for a month. The results of the studies show that no case of diarrhea was registered among calves receiving the enzyme-probiotic supplement “Immunobacterin-D”. Among the animals of the control group, 66.7 % had digestive disorders – dyspepsia. Subsequently, such animals had a lower growth rate. Enzyme-probiotic supplement “Immunobacterin-D” also contains Bacillus Subthilis, Bacillus Licheniformis and enzymes and protease and lipase – it provides a polyvector effect in the digestive tract in general and scarring in particular. It was found that on the fourteenth day of feeding probiotic-containing drug “Immunobacterin-D” to calves of the experimental group, the number of bacteria probably increased by 83.5 %; ciliates – by 65.0 %; endodynomorphs – by 24.3 %. After one month of the experiment, the number of bacteria in the experimental group probably increased by 94.3 %; ciliates – by 40.5 %; endodynomorphs – by 26.7 %, compared with the control (P < 0.001). The obtained data of registration of the first chewing gum in calves prove that the components of the enzyme-probiotic supplement “Immunobacterin-D” accelerate the population of microflora and the development of scar digestion in calves 2.5 times compared to calves in the control group. Prospects for further research are to study the effect of enzyme-probiotic supplement “Immunobacterin-D” on the indicators of scar fermentation of calves.

Dendrobium officinale (D. officinale) is a valuable medicinal plant with a low natural survival rate, and its shade-avoidance response to far-red light is as an important strategy used by the plant to improve its production efficiency. However, the lncRNAs that play roles in the shade-avoidance response of D. officinale have not yet been investigated. This study found that an appropriate proportion of far-red light can have several effects, including increasing the leaf area and accelerating stem elongation, in D. officinale. The effects of different far-red light treatments on D. officinale were analysed by RNA sequencing technology, and a total of 69 and 78 lncRNAs were differentially expressed in experimental group 1 (FR1) versus the control group (CK) (FR1-CK) and in experimental group 4 (FR4) versus the CK (FR4-CK), respectively. According to GO and KEGG analyses, most of the differentially expressed lncRNA targets are involved in the membrane, some metabolic pathways, hormone signal transduction, and O-methyltransferase activity, among other functions. Physiological and biochemical analyses showed that far-red light promoted the accumulation of flavonoids, alkaloids, carotenoids and polysaccharides in D. officinale. The effect of far-red light on D. officinalemight be closely related to the cell membrane and Ca2+ transduction. Based on a Cytoscape analysis and previous research, this study also found that MSTRG.38867.1, MSTRG.69319.1, and MSTRG.66273.1, among other components, might participate in the far-red light signalling network through their targets and thus regulate the shade-avoidance response of D. officinale. These findings will provide new insights into the shade-avoidance response of D. officinale.

When balancing ration it is necessary to remember that the active factors of feeding are not the feed itself, but the content of nutrients and biologically active substances in them. It has been developed and physiologically justified feeding rations of cows during increasing the milk yield period, which are based on succulent feed, hay, grain and rapeseed presscake and a source of minerals and vitamins PVMA have been used. The experimental part of the work has been carried out in the winterstall period in the educational and experimental farm in the State Agrarian University of the Northern Trans-Urals. It has been found that from cows of the experimental group during the increasing the milk yield period 1503 kg of milk containing 3,98 % fat and 2,87 % protein has been obtained. Animals of the experimental group exceeded cows of the control group in milk yield by 90 kg (P > 0,95), in terms of fat and protein content in milk their superiority was 0,37 abs.% (P > 0,999) and 0,21 abs.% (P> 0,999). Input into the rations of lactating cows rapeseed presscake in the amount of 2 kg/ head/day and PVMA in the amount of 100 g during 3 months of lactation gives an increase in productivity for the entire lactation in the experimental group by 572 kg of milk with additional products by 2745,2 Rubles can be obtained more. The positive effect of the input of rapeseed presscake in the rations of lactating cows in the amount of 2 kg/head has been established/day and PVMA in the amount of 100 g in the period of following on the subsequent productivity of animals.

The animal husbandry cannot develop successfully without complete balanced feed and optimal forage supply. This article deals with the chemical composition of chlorella suspension. The ration is balanced with seaweeds as well as premixes, vitamins and bio supplement for the last decades. These seaweeds include chlorella - a representative of green microscopic algae. The use of chlorella allows for multi-factor balancing of the diet in accordance with modern feeding standards, which increases the productive effect of feed and significantly increases the transformation of nutrients into livestock products. This is arelevant issue of modern animal husbandry. The chlorella suspension was material for scientific research. It was made on the farm “In Samvel”, Ovidiopol District. According to the result of researches that took place on the farm " In Samvel", Biliayevka District, Odessa Oblast and SERF "Yuzhnyi" OSAGES NAAS, new data concerning chemical composition, the positive influence of investigated chlorella suspension on the growth and development of finishing pigs as well as feed costs by 1 kg of growth were obtained. It has been established that the chemical composition of chlorella suspension takes a special place among all feed additives used in farm animals feeding. It has been established that the additional use of chlorella suspension in the ration of finishing pigs of Large White breeds contribute to the increase of average daily gains by 121.9% against the control group in which chlorella suspensions was not given. Feed conversion to obtain1 kg of pigs live weight gain in the control group was 5.1 kg, in the experimental group - 4.2 kg and feed conversion index in the experimental group was higher by 21.4%. Thus the results of researches indicate the positive effect of investigated chlorella suspension on the growth anddevelopment of finishing pigs. Due to the obtained results, we can state that the chemical composition of the suspension chlorella takes a special place among all feed additives used in farm animals feeding. Chlorella has higher indicators of chemical composition, the amount of protein, vitamins and minerals in comparison with plant fodder and crops of agricultural production.

The paper highlights the research conducted in order to assess the effect of different doses of thyme extract on the productive properties and livability of broiler chickens. The experiment was conducted at a broiler poultry farm with a closed production cycle; the experiment assumed the control group and 5 experimental groups where each group contained 37 broilers at floor housing. The broilers of the 1st experimental group were fed with the extract of medicinal plant thyme dosed 2 mg/kg; broilers of the 2nd group received thyme extract dosed 4 mg/kg; 3rd group of broilers – 6 mg/kg, 4th group -8 mg/kg, and the dosage of the thyme extract was 10 mg/kg for broilers in the 5th experimental group. The authors controlled the live weight of broilers in each group by means of individual weighing every 7 days. Using this data the researchers calculated average daily body weight gain, absolute and relative gain; feed consumption was daily calculated. Feed consumption became the basis for calculating feed costs per a kilo of live weight gain. The authors recorded the number of daily fallen chickens. The data on poultry loss was the basis for calculating poultry livability. In order to assess production efficiency, the European productivity index was calculated. The research results indicate the efficiency of thyme extract application in different doses when feeding the broiler. Application of thyme extract in feeding meat poultry allowed to increase productive properties of broilers from experimental groups from 2.3 to 4.7%, reduce feed costs per a kilo by 1.1-8.1%, increase poultry livability on 2.7-8.1% and increase the European productivity index in the experimental groups on 0.2 21.3%.
