This research aims to realize the adaptive and productive capacity of calves with immunotropic agents PS-6 and Prevention-N-E. The object of the research was black-and-white calves, which were transferred to individual pens a day after birth and kept there until 30 days of age, then in open-air pavilions until they reached 180 days of age, that is, they were reared using adaptive technology. According to the principle of analogs, 45 calves of 1 day age were selected, were divided into 3 groups: control, 1st experimental, and 2nd experimental. To increase resistance to the pressure of environmental factors and realize the bioresource potential of the adaptive and productive traits of the organism, the calves of the 1st and 2nd experimental groups were injected intramuscularly immunotropic preparations PS-6 and Prevention-N-E respectively, at a dose of 3 ml per animal on the 2nd-3rd and 7-9th days of life. The animals of the control group were not exposed to immunoprophylaxis. The morphological blood profile of calves was studied against the background of the application of biological products. Thus, intramuscular injection of immunotropic agents PS-6 and Prevention-N-E into calves had a positive effect on the morphological blood composition. The number of erythrocytes in the blood of calves of the 1st and 2nd experimental groups at the age of 30 days was significantly higher than the control values by 5.4 and 6.4%, respectively (P<0.01). The concentration of hemoglobin was significantly higher in the blood of the calves of the 1st and 2nd experimental groups, starting from 30 days of age, by 6.3-11.7% and 6.7-14.4%, respectively. White blood counts in the blood of animals of different groups did not have a statistically significant difference. Consequently, the use of immunotropic drugs PS-6 and Prevention-N-E in calves activates the erythrocyte lineage of hematopoiesis, without significantly affecting leukopoiesis. The results of periodic weighing of calves showed that at the age of 60, 90, 120, 150, 180, 360, and 540 days, the live weight of young animals with the injection of the immunotropic agents PS-6 was significantly higher than the control values by 2.6, 3.4, 5.0, 6.2, 7.0, 9.4 and 12.2 kg (P<0.05-0.01), and with the application of Prevention-N- E - by 3.6, 4.8, 6.6, 8.0, 9.0, 12.2 and 16.4 kg, respectively (P<0.05-0.001).

The reliability of the results obtained in scientific and economic experiments on the study of the effectiveness of the use of various feed components, including biologically active substances in the rearing of broilers needs to be confi rmed in production conditions. The purpose of the research was to study the joint use of enzyme drugs and lecithin in the rearing of broiler chickens. The results of production experiment on the study of the effectiveness of the joint inclusion of enzyme drugs Sunzyme and Sunfyse 5000 as well as lecithin in the diet of broiler chickens of the cross Ross-308 have been presented in the article. Production tests have been carried out under the conditions of the breeding farm “Achkhoy– Martanovsky” in the Chechen Republic. The duration of the experiment was 45 days. For research on the principle of analog groups two groups have been formed: a control group and an experimental group of 1000 heads in each. The broilers of the control group have been fed compound feed prepared in accordance with the growing period and consisting mainly of grain components of local production. The broilers of the experimental group have been fed the same compound feed, but with the addition of two enzyme drugs Sanzyme and Sanfyse 5000 (100 g/t of feed) as well as lecithin (10 g/kg of feed). The results of the production experiment fully confi rmed the data obtained in the scientific and economic experiment. The positive effect of the joint use of the studied enzyme drugs and lecithin has been manifested in all the studied productive traits. In particular, the increase in live weight of broilers increased by 12,1 %, slaughter yield by 3,5 %, the yield of carcasses of the 1st category by 3,0 %. The main economic indicators also found their confirmation: feed consumption per unit of growth decreased by 11,7 %, additional profit was received in the amount of 27308,2 rubles, the level of profitability of broiler rearing increased by 18,4 %.

The purpose of the research is to increase the effectiveness of the supplement Reasil on the growth of milk-fed calves. For the scientific and economic experience, three groups of calves were formed (control, 1 and 2 experi-enced). Groups of animals of 10 heads were formed according to the principle of analogues. The indicators of live weight, growth and blood of calves were studied after Reasil use in a diet: Reasil HumicVet as a liquid form, and Reasil Humic Health – reduced to powder. In the experiment, animals of a black-and-white breed were used. The Reasil feeding in the diet contributed to an increase in the live weight of milk-fed calves in the 1-st and the 2-nd experimental groups at two months of age by 5.65 and 5.48 kg (or by 7.4 and 7.2%), respectively, compared to the indicator of the control group analogues. The average daily growth of calves of the experimental groups exceeded this indicator of control animals by 96 and 82 g, respectively. The blood of calves of the 1st and 2nd experimental groups, showed that hematoglobin was higher by 15.7 and 11.4%, red blood cells – by 16.5 and 15.1%, and the alkaline reserve – by 5.2%, compared with blood of calves from the control group, which indicates the activation of metabolic processes in the body. The total protein amount in the blood serum of animals from the experimental groups increased by 8.4 and 5.9% respectively, compared to the tests of calves from the control group. The albu-min content of animals of the 1st experimental group tested was higher by 5.3%; from the 2nd experimental group there was no significant difference compared to the control. The number of gamma-globulins in the blood of ani-mals of the experimental groups increased, which indicates an increase in defense reaction of animals. The con-tent of calcium in the blood serum of calves from the experimental groups was higher by 8.3 and 5.9%, phosphorus – by 4.8 and 2.4%, which indicates a more effective use of these mineral elements.

Breeding, preserving, and successfully rearing young animals resistant to various environmental influences is one of the main parameters of effective livestock management. The study aimed to study the indicators of natural resistance and the growth rate of calves under the influence of dietary supplements. The studies were carried out on four groups of black-and-white calves, 10 heads each, at the age of 2-5 months. The dairy calves of the control group were fed according to the ration adopted on the farm (basic ration, including cereal-legume hay, whole milk, milk replacer, concentrates, chalk, salt). In addition to the main diet, the animals of the experimental groups were given a dietary supplement. At 2-3, 3-4, and 4-5, months of age, calves were given 12-23, 19-38, and 23-47  g.head-1 of dietary supplement per day, respectively. The article deals with the effect of a forest biomass supplement on the morphophysiological parameters of calves. Biochemical blood analysis and the features of metabolic processes in the bodies of animals are studied. The results indicated that the use of a dietary supplement at a dosage of 30 g/head of cattle per day contributes to the highest increase (9.9%) in live weight gain of experimental animals and an improvement in natural resistance parameters (bactericidal activity of blood serum, phagocytic activity of neutrophils). Based on the data of biochemical and haematological blood tests, the authors conclude that the inclusion of a dietary supplement in the diet of calves has a positive effect on the indices of natural resistance and the course of nitrogen metabolism.

ABSTRACT Objective:  To evaluate the proliferation and morphology of human osteoblasts cultured on two brands of mini-implants after 24, 48, and 72 hours, in addition to the chemical composition found on their surface. Materials and Methods:  Two brands of mini-implant (Morelli and Neodent) were evaluated; polystyrene was used as a control group (n  =  3). Osteoblasts were cultured on the surface of sterilized mini-implants in a CO2 incubator at different time periods (24, 48, and 72 hours). Osteoblast proliferation was quantified by scanning electron microscopy using up to 5000× magnification, and cell morphology was analyzed by a single observer. For the chemical analysis, spectroscopy X-ray fluorescence was used to identify and quantify chemical components on the surface of the mini-implants. Results:  Two-way ANOVA showed no significant interaction between the factors studied (P  =  0.686). A Tukey test revealed no significant difference in osteoblast proliferation between the mini-implants at all studied periods; however, a difference in cell proliferation was detected between the Neodent and the control group (P  =  .025). For all groups, time had a direct and positive effect on osteoblast proliferation (P &lt; .001). The significant elements present in both brands of mini-implants were titanium, aluminum, vanadium, and iron. Conclusions:  Osteoblast proliferation was present on the mini-implants studied, which increased over time; however, no significant difference between brands was observed. No difference was seen between the mini-implants evaluated in terms of chemical composition. Cell adhesion after 72 hours suggests that areas of bone remodeling can be achieved, thus initiating the process of mini-implant anchorage.

The paper presents the results of studies of milk productivity of black-and-white cows depending on the age of the first insemination and live weight at the first calving in the conditions of the Irkutsk region. The dynamics of heifer rearing by year, milk productivity of cows in the 1st and 3rd lactations depending on the intensity of their development has been studied. The experiment was conducted on farm materials from the Irkutsk Region using generally accepted zootechnical, analytical, variation and statistical research methods from 2016 to 2020. Live weight of heifers at all ages met the requirements of the elite and elite-record classes. Analysis of the data showed that the growth rate of the animals increased during 5 years (6.0%, 6.8, 2.3 and 4.8% respectively with a significant difference p ≥ 0.90). With the increased intensity of heifer rearing, an increase in milk yield over 305 days of the first lactation was observed. The highest milk production was noted in the 1st (5309-5476 kg) and 3rd (5418-5817 kg) lactations in cows with the first fruitful insemination at 13-14 months. The lowest 1st and 3rd lactation yields are obtained from cows inseminated at 20 months of age or older. Higher milk production in the first and third lactations was obtained from cows with a live weight at first calving of 541-550 kg, 551 kg and higher (5197-5164, 5436-5545 kg respectively). Less milk production was obtained from cows with a live weight at first calving of up to 500 kg (4567-5122, 4943-5009 kg). The results obtained make it possible to reveal the influence of the intensity of rearing heifers on the productive qualities of cows.

SUMMARYTwo experiments were conducted to compare the milk-producing value of dried forages in the form of cobs and pellets as replacements for a standard dairy concentrate. Four levels (0·33, 0·44, 0·55 and 0·66 kg/kg milk) of dried forage or standard dairy concentrate were offered in addition to a basal ration of 6 kg hay and 2 kg standard dairy concentrate. In both experiments the rate of eating by the cows of cobs was significantly slower (P<0·05) than that of pellets. No significant difference was found between the cobs and pellets in either experiment in their value for milk production. In Experiment 2 the standard dairy concentrate had a non-significantly higher (P>0·05) milk-producing value than the dried lucerne. Level of feeding had a significant positive effect on the milk yield (P< 0·001) of cows offered the dried grass and lucerne and on the milk solids- not-fat content (P<0·05) and live weight (P<0·01) of cows offered the dried grass, lucerne and standard dairy concentrate.

The experiment has been carried out on a crossbred stock of young pigs in the period 2015–2017 under the conditions of JSC CHC “Krasnodonskoe” in the Ilovlinsky district in the Volgograd region. The purpose of the research was to study the effectiveness of the effect of the anti-stress drug Feed-Food Magic Antistress Mix in intensive pig rearing on the productive traits and quality of the products obtained, as well as the estimated economic indicators. In order to conduct a scientific and economic experiment at the age of 60 days young pigs were divided into 2 experimental groups (control and experimental) according to the principle of pair analogs. Each group contained 25 heads. The difference between the control and experimental groups was that the animals in the control group have received the main diet, and the experimental group has received the anti-stress drug Feed-Food Magic Antistress Mix in addition to the main diet. In the experimental group of pigs when this drug was administered in the age 180 days the live weight parameter was higher than in the control group by 1,55 kg. Clinical indicators of young pigs were within the physiological norm. The pre-slaughter weight in the experimental group has increased by 4,86 % compared to the control group. Due to the use of an anti-stress drug the slaughter weight of animals in the experimental group has increased by 6,69 %. In comparison with the control group the slaughter yield in the experimental group has increased by 1,18 %, in which this indicator was at the level of 67,62 %. The morphological composition of carcasses in animals of the experimental group was also improved. Meat yield has increased by 0,95 %. The yield of fat and bones has decreased by 0,59 and 0,36 %. The weight of internal organs was also superior in the experimental group of pigs. Due to the use of the anti-stress drug the level of profitability in the experimental group of animals has increased by 11,69 %.

This study examined the effect of descriptive norm messaging information on the relationship between haptic input and balance control. Participants were randomly assigned to either a message group where they balanced with haptic input after receiving a descriptive norm message about the positive effect of haptic input or a control group. Findings from an analysis of covariance revealed a significant difference between the two groups. Those in the descriptive norm message group had better balance control than those in the control group. These findings suggest that efforts designed to improve balance control through haptic input may be enhanced through normative messaging.

SUMMARYThe carcass characteristics of young adult female pigs (gilts) slaughtered after weaning their first litters have been investigated using three groups of 19 Landrace × (Landrace×Large White) gilts. In two treatment groups gilts were mated at their pubertal oestrus and suckled their piglets for 5 to 11 and 35 to 42 days respectively. These gilts were slaughtered on average 10 days after weaning. A third control group consisted of unmated gilts slaughtered at 118 kg live weight.There was no significant difference in the killing-out percentage for the three groups. The carcasses of the gilts which farrowed contained significantly less fat (P<0·001) than those of the unmated controls. The carcasses of the farrowed gilts had significantly lighter middle sections (P<0·001) and significantly heavier shoulders (P<0·001) than the controls.Despite the variations in tissue yield and distribution, the yield of prime joints for the gilts which had farrowed was only 0·62 percentage units less than that of the controls.No commercially significant variations between groups in meat quality were observed.
