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 paper shows the results of production and chemical compo­sition of cow’s milk on a farm MILKO-HF, Prilep, R. Macedonia with capacity of 100 cows of Holstein-Frisian breed divided into two groups (control and experimental). In control group I which was fed in a standard way of nutrition (ration used on the farm), average daily production of milk per cow ws 22.49 kg with the following chemical composition of milk: average daily content of milk fat is 3.75%, protein 3.57%, lactose 4.65%, nonfat dry matter 9.56% and total dry matter 13.31%. In experimental group II which were fed with the ration according to normatives, average daily production of milk per cow is 24.04 kg with the following chemical composition of milk: average daily content of milk fat is 3.99%, protein 3.57%, lactose 4.65%, non-fat dry matter 9.58% and total dry matter 13.57%. The obtained results show the increase in milk production for 1.55 kg-6.89% and better chemical composition of milk in the experimental group of cows. Thus, dry matter was increased from 13.31% to 13.57%-1.95%, milk fat content from 3.75% to 3.99%-6.4%, nonfat dry matter from 9.56% to 9.58%-0.21%, while the content of protein and lactose stayed on equal level. It was determined that the normed nutrition has influenced on production increase and better chemical composition of milk without unnecessary spent high level of nutrient i.e. nutrition of cows according to recommended normative.

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.

Promising direction in ensuring food security and independence of Russia is the widespread use and study of new feed additives of probiotic action. Today, probiotic preparations are widely used in dairy farming. They support the positive microbial balance of the gastrointestinal tract and stimulate the activity of the digestive, motor-evacuation, hormonal and immune systems. Authors studied the efficiency of the composition of 2 strains of Bacillus subtilis during 14 days after calving (1 experimental group) and 14 days before calving and 14 days after calving (2 experimental group) in the technology of milk production and improving its quality. In the process of conducting scientific and industrial experience, modern research methods were used that were able to obtain high-quality and most informative data on the processes occurring in the body. Analysis of the results of hematological blood parameters of animals of all groups confirmed the physiological of recovery of the cow's body in the postpartum period, but with different degrees of intensity. Animals of the experimental groups reached peak milk production. By the end of the third month in group 1, milk productivity was 28.94±6.84 kg, in group 2 - 32.17±3.33 kg, which formed an increase of 6.44% and 15.59% relative to the background values. In the control group of cows-27.90±7.25 kg. By day 150, the average daily milk yield in animals of the first group was 25.07 ± 4.38 kg, the second - 25.33 ± 2.52 kg, control 22.75 ± 8.82 kg. Milk quality indicators - fat and protein content in animals receiving probiotic supplements were variable. In the milk of animals of the 1st and 2nd groups, the average fat content was recorded 3.69 g / 100g and 3.74 g / 100g, respectively, and the average protein content was 3.104 g / 100 g and 3.240 g / 100 g. In peers of the control group, the fat and protein content in milk was determined to be 3.79 g / 100 g and 3.016 g / 100 g. The studies established and proved the promise of the widespread introduction of probiotic in dairy cattle breeding, which was based on the composition of endo- and exometabolites of 2 strains of Bacillus subtilis. There was an improvement in the physiological status and an increase in the milk productivity of Holstein cows of the black-motley breed.

In Bangladesh some researchers have done several studies to find the correlation of simple diffuse goiter with arsenic level but no one conducted any study to find the differences of urinary iodine, urinary arsenic, radioiodine uptake, the thyroid stimulating hormone (TSH) and free thyroxin (FT4) levels between goitrous and non goitrous. That is why, in this research an attempt has been made to compare the urinary iodine, urinary arsenic, radioiodine uptake, TSH and FT4 levels between experimental group with simple diffuse goiter and healthy control group. In this study another purpose has also been made to find the associations between different pairs of variables for both experimental and control group. In this study we have tried to find the impacts of arsenic level on simple diffuse goiter. This is a case-control analytical study. The study is carried out in the Institute of Nuclear Medicine and Ultrasound, in collaboration with the thyroid out patient department of Bangabandhu Sheikh Mujib Medical University. A total of eighty five (85) subjects are included in the study. Among the 85 subjects, a sample of forty five is considered for experimental group with simple diffuse goiter and another sample of forty is considered for healthy control group without any thyroid disease. From the experimental results it has been found that, the arsenic levels, FT4 and radioiodine uptake levels at 2 hours between the experimental and control groups are significantly different but the urinary iodine levels, TSH levels and radioiodine uptake levels at 24 hours between the experimental and control groups are not statistically different. From the experimental results it has also been found that there is significant differentiation between experimental and controls groups in respect of association between different pairs of variables. In this study, another significant finding is that iodine deficiency is not only the factor of causing simple diffuse goiter, but arsenic level is also one of the most important factor of causing simple diffuse goiter.
