Abstract. The purpose of the research was to study the effect of feeding by sainfoin haylage in the dry period (21 days before calving) and in the period of early lactation (50 days after calving) on the metabolic processes of dairy cows and the results of reproduction. The article gives the brief description of sainfoin (Onobrychis arenaria Kit.) as a valuable feed protein crop that can be successfully cultivated in Perm region conditions. High sugar content in sainfoin forage was noted 4.86 %, which is 1.6 times higher compared with standard class 1 for legume haylage first class. Methods. Experiments for use of sainfoin haylage in feeding highly productive cows were conducted in 2018. Cows of the experimental groups received a diet including sainfoin haylage. Cows in the control group received 5 kg of poaceous grass hay as a fodder. The first experimental group got 50 % of forage dry matter as sainfoin haylage. The second experimental group received 100 % of forage dry matter as sainfoin haylage. Results. Hay replacing by equal dry matter amount of sainfoin haylage provided positive effect on immuno-biochemical parameters of cows blood. The protein content increased in the blood plasma of cows during the time of the experiment: in the second experimental group by 4.3 g/l (5.47 %, p < 0.01) and reached 82.80 g/l, in the first experimental group by 1.72 % (p < 0.05), in the control – by 2.28 % (p < 0.05). Feeding sainfoin haylage to cows had a positive effect on their reproductive functions. The service period for cows of the second experimental group was shorter by 8.1 days (9.28 %, p < 0.01) compared with the first experimental group and by 21 days (24.05 %, p < 0.05) shorter than in the control group. The scientific originality of the work is that for the first time the biochemical composition of sainfoin was studied thoroughly in Perm region and the results of sainfoin haylage feeding to animals were presented.

The results of studies of the use of rhaponticum carthamoides for feeding dairy cows are presented. The experiment was carried out on Holstein cows of black-and-white breed in Perm Territory. Vitaminherbal fl our from green mass of rhaponticum carthamoides at a dose of 0.4 and 1.0 kg per head per day in the period of 10-16 days before calving and in the fi rst 30 days of lactation was introduced into the feeding rations of two experimental groups of cows. High sugar content in rhaponticum carthamoides (from 4.15 to 11.2% in dry matter and metabolic energy from 10.87 to 12.12 MJ/ kg) was noted. In the studied material from this plant, the content of the 20-hydroxyecdysone was 0.49% of active ingredients in the dry matter of the product at a rate of 0.25%. The introduction of rhaponticum carthamoides in the diet of feeding animals contributed to the increase in the intensity of metabolic processes in the body. A gradual increase in cholesterol levels in all experimental groups was noted. The most signifi cant growth was observed in cows of the second experimental group by 0.82 mmol / l or 29.50% (p <0.01). Compared with the fi rst experimental group, the increase was 0.13 mmol / l or 5.2%, and the control group – 0.36 mmol / l or 14.17%. Stimulation of metabolic processes in the body of cows of the experimental groups had a positive impact on reproduction, which was manifested in the reduction of the service period duration, compared with the control group.

This Research Communication describes the effects of a synthetic analogue of the Bovine Appeasing Pheromone (BAP) on milk parameters in Valdostana dairy cows during the first turning out from tie-stalls to confined lowland pastures around the farms. Thirty healthy lactating Valdostana cows were enroled in the study and randomly divided into 2 groups: experimental group (EG, n = 15) and control group (CG, n = 15). The two groups were separately housed in the same farm and managed outside in two different pens. Treatment (BAP and solution) and control (solution only) were poured on the nuchal skin area between the horns when the animals were inside the farm at the feeding rack every 7 d for 28 d (T0–T4). Milk samples were evaluated at the same time points (T0–T4). Daily milk production (kg/day) was higher in the EG than in the CG, particularly during the first day after the turning out to pasture (T1). Somatic Cell Count (103 cells/ml) was higher in the placebo group than in the EG, especially at T1. Proteins, fat, fat-free dry matter and casein (g/100 g) were not affected by the treatment. In T1 urea (mg/dl) content was higher in CG vs. EG, suggesting a more correct metabolic balance in the group treated with BAP. The use of BAP appears to modulate adaptation in ways that may improve dairy cow performance in the context of changes in management routines.

A study of the effectiveness of the use of feed additive Liatoxil in vivo in broiler chickens to study the ability of feed additives to improve digestion and affect the digestibility of nutrients. For research was formed on the principle of analogues -day age. Feeding of the control group was carried out with standard feed. Feeding of the experimental group was carried out with standard feed, in which the feed additive Liatoxil was added at the rate of 2 g / kg. The calculation of the digestibility of nutrients of the experimental and control feed was determined by their content in the feed and manure in terms of absolutely dry matter. It is established that the studied feed additive has a positive effect on the digestibility of feed nutrients. As a result of the use of feed additive Liatoxil, the digestibility of organic matter increased by 2.8 % compared to the control. The coefficient of protein digestibility in animals of the experimental group exceeded this indicator of the control group by 4.2 % and was 93.3 % against 89.1 % in the control. The digestibility of crude fat in poultry of the experimental group was 77.8 % and also exceeded by 2.0 % the value of the control group, which was 75.8 %. The studied feed additive did not significantly affect the digestibility of crude fiber, which was 23.3 % in the control and 23.5 % in the experiment. At the same time, the obtained data show that in the animals of the experimental group the digestibility of nitrogen-free extractives was 87.5 %, which is 2.8 % higher than this indicator of the control group.

Цель исследования изучение биохимического статуса организма телят 1 3месячного возраста при применении вермикулита. Опыт на животных проводили в течение 60 дней. Для опыта были отобраны, по принципу аналогов, 3 группы телят молочного периода выращивания по 9 голов в каждой. Телята контрольной группы получали стандартный рацион, телятам 1й опытной группы к основному рациону добавляли 2 на голову в сутки вермикулита, 2й опытной группе 3 на голову в сутки. Использовали вермикулит (ГОСТ 1286567), выпускаемый ОАО Ковдорслюда . Для изучения состояния обменных процессов в организме подопытных животных отбирали кровь из яремной вены после утреннего кормления два раза: в начале опыта и через месяц после его окончания. Исследования показали, что использование вермикулита в кормлении молочных телят, благодаря многогранным буферным, ионообменным и сорбционным свойствам положительно сказалось на белковоминеральном обмене животных и интенсивности их роста. В опытных группах уровень общего белка вырос в 1,04 1,06 раза, достоверно повысился к концу исследований уровень альбуминов. Целесообразно для нормализации обменных процессов в организме молочных телят использовать добавку вермикулита в количестве 2 и 3 к сухому веществу рациона.The purpose of the research is to study the biochemical status of the organism of calves 13 months of age with the use of vermiculite. The animal experiment was carried out for 60 days. 3 groups of calves of the dairy period of growing of 9 animals in each were selected for the experiment according to the principle of analogues. The calves of the control group received a standard diet, 2 per head per day of vermiculite was added to the main diet of the calves of the 1st experimental group, and the 2nd experimental group 3 per head per day. We used vermiculite (GOST 1286567) manufactured by OAO Kovdorslyuda. To study the state of metabolic processes in the body of experimental animals blood was taken from the jugular vein after morning feeding two times: at the beginning of the experiment and one month after its completion. Researches have shown that the use of vermiculite in the feeding of dairy calves due to its multifaceted buffering, ionexchange and sorption properties has a positive effect on the proteinmineral metabolism of animals and their growth rate. In the experimental groups the level of total protein increased in 1.04 1.06 times and the level of albumen significantly increased by the end of the research. It is advisable to normalize the metabolic processes in the body of dairy calves to use the additive of vermiculite in an amount of 2 and 3 to the dry matter of the diet.

The goal of the study was to test the possibility of raising milk zinc (Zn) concentration by increasing the supplementation of Zn, and to assess the effect on the somatic cell count. The experiment was performed at a farm with Czech Pied cattle, with 500 dairy cows and average milk yield 6,390 l. The experiment included 40 dairy cows, assigned to either an experimental (E, n = 20) or a control group (C, n = 20) based on the principle of balanced pairs (efficiency, lactation stage). The experimental group was supplemented Zn in the chelate form (Bioplex Zn, Alltech Inc., Nicholasville, KY), at the dose of 440 mg Zn per animal per day. Blood and milk samples were taken at the start of the experiment and at the end of months 1, 2 and 3. The average milk Zn concentration during the experiment was 57.36 ± 10.54 μmol l-1, ranging from 38.02 to 86.13 μmol l-1. A trend towards a positive effect of Zn supplementation on the health of the mammary gland was identified in association with the somatic cell count, which was significantly lower in the experimental group (114.90 ± 68.7 103 ml-1 vs. 208.60 ± 148.1 103 ml-1; p < 0.05) by the end of month 3. A negative correlation was found between the somatic cell count and Zn concentration in milk (y = -0.0327 x + 61.557; r = -0.441; p < 0.01). Our results indicate that milk Zn concentration is not directly affected by the level of zinc supplementation in the feed ration, but zinc supplementation has a positive effect on the somatic cell count.

Pragmatic Instruction

Over the last three decades, a growing number of studies have investigated the effects of instruction on the acquisition of pragmatic features in L2. The bulk of this research has focused mainly on the teaching of English as a second/foreign language. However, instructional pragmatic studies in L2-Russian are lacking. The main purpose of our study is to contribute towards filling this gap by analysing the effects of pragmatic instruction on the acquisition of two speech acts by Italian learners of Russian. Furthermore, we aim to explore whether the Multimodal Russian Corpus (MURCO), a multimedia subcorpus of the Russian National Corpus, can be an effective tool for teaching speech acts in L2-Russian. Our research was composed of one experimental group (n = 18) and one control group (n = 11); each was composed of two intact classes of Italian university students at an intermediate level of L2-Russian, who were pre- and post-tested using a written discourse completion task. The experimental group was subjected to a programme of pragmatic instruction – eight thirty-minute MURCO-based lessons devoted to requests and advice, while the control group was taught according to the standard syllabus, that is, with no pragmatic instruction. The results revealed that the use of the target pragmatic features varied significantly in the experimental group, but not in the control group, thus showing a general positive effect of the instructional treatment based on the MURCO corpus. However, some limitations were identified with regard to the usability of this tool by teachers and learners.

Abstract the aim of our study was to evaluate influence of probiotic agents (Lactovita) and seaweed extracts (Biopolym) with antidiarrheal effects on the prevention of diarrhoea in calves. In the experiment 22 experimental and 22 control calves were observed. The results of the observed incidence of diarrhoea in the control and experimental groups showed a positive effect of probiotic Lactovita and seaweed extracts Biopolymer. 32% of calves in the experimental group and 45% of calves in the control group became sick. Unfortunately, we could not demonstrate the statistical significance of these differences. The weight gains found in the 4th week after birth were by 37.6% higher in the group with Lactovita and Biopolym than in the control group.

Abstract: This study evaluated the effects of varying amounts of melon with high sugar content offered to sheep without prior melon experience and that were not adapted to consuming it. We used 12 eight-month-old, rumen-cannulated crossbred sheep weighing 25 kg each. The animals received a base diet of roughage, and then half were randomly selected to have 25% of their diet replaced with melon (G25%) and the other half had 75% of their diet replaced with melon (75%). Ruminal fluid was collected before administration of melon and at 0, 3, 6, 12, 18, and 24 h after the administration of the fruit. Sheep from the G25% group presented volatile fatty acid ruminal acidosis (sub-acute) between 3 and 6 h after consumption. This acidosis was characterized by a rumen pH slightly lower than 5.6, increased discrete L-lactic acid content, and increased redox potential (RP) and methylene blue redox (MBR) time of the ruminal fluid. The G75% group presented lactic ruminal acidosis at T6h, characterized by a rumen pH lower than 5.0, high lactate-L content, increased RP and MBR time, and increased ruminal fluid osmolarity. Therefore, offering large amounts of melon (75% of dry matter (DM)) is not recommended but 25% of DM of this fruit can be used safely.
