The organization of feeding of highly productive cows is one of the most difficult tasks in dairy cattle breeding. The purpose of the work was to study the influence of natural mineral additive on the productivity, composition and some technological qualities of milk of cows of Black-and-White breed of Ural type. Research and production experiment has been carried out in CJSC “Glinki” in the Ketovsky district in the Kurgan region on Black-and-White cows. The influence of bentonite additive in the ration of highly productive cows during the period of increasing the milk yield on the composition and technological quality of milk and dairy products has been determined. In general, for the first 100 days of lactation the cows of the experimental group have produced by 191 kg more natural fat milk or 8,4 %, compared to the control group. In terms of 4 % milk from animals of the experimental group has been got by 233 kg or 9,3 % more than of the control group. The yield of milk fat in the experimental group was by 10,44 kg or 12,9 % more than the control group. The difference in milk protein yield for 100 days of lactation was 7,34 kg or 9,8 %. The economic indicators (prime-cost, profitability) of milk production when feeding the mineral additive bentonite to cows have been calculated. With an increase in the total cost of obtaining milk from cows of the experimental group, caused by higher milk yields and the purchase of bentonite, the revenue from the sale of milk from this group was by 7,83 thousand rubles or 8,4 % more. As a result, milk production from animals of the experimental group was by 3,44 % more efficient. It has been found that the inclusion of bentonite in the composition of concentrated feed in the amount of 400 g/head/day allowed to reduce their expenditure, as well as EFU and digestible protein, which ultimately provided a higher level of profitability of milk production.

The feasibility of using the complex mineral and vitamin feed additive “Nadezhda” in the rations of lactating first-calf heifers of Black-and-White breed has been examined in the article. It has been established that feed contain a low content of elements such as calcium, phosphorus, magnesium, sulfur, manganese, copper, zinc and cobalt. The ratio of nutrients and minerals, the degree of their availability for assimilation by the body does not provide their need. The use of the complex mineral and vitamin feed additive contributed to an increase in the milk productivity of first-calf heifers and the quality of milk, feed consumption per unit of production. All tested recipes of the complex mineral and vitamin feed additive, which have different versions of macro-, microelements and vitamins in their composition had a positive effect on the metabolic processes in the body of animals. For the production of 1 kg of milk in the experimental groups of cows less metabolic energy was spent by 5,09 (P < 0,05) and 8,06 % (P < 0,05), respectively, raw protein by 5,19 and 8,19 % (P < 0,05), digestible protein by 5,12 (P < 0,05) and 8,15 % (P < 0,05) compared with the animals of the control group. At the same time from the cows of the 1st experimental group have been received more milk by 151,6 kg in the amount of 2489 rubles, from the 2nd experimental group by 250,6 kg of milk in the amount of 4248,0 rubles. The prime cost of production of 1 kg of milk in cows of the 1st experimental group in comparison with the animals of the control group decreased by 0,72 rubles, and the 2nd experimental group by 1,21 rubles. The level of profitability of milk production in cows have been fed with additive recipe No. 1, in comparison with the animals of the control group increased by 3,71 abs.%, recipe No. 2 by 9,91 abs.%.

The article contains information on the state of the processes of lipid peroxidation (LPO) in fresh cows under the influence of stress reaction caused by labor and the beginning of the lactation period. To reduce oxidative stress in the body of fresh cows, antioxidants were used in the form of preparations “E-selenium” and “Butofan”. The aim of the research was to determine the effect of vitamin-containing preparations “E-selenium” and “Butofan” on the productivity of fresh cows, the quality of milk and butter, made from it. The studies were carried out during the winter-stall period on one of the farms of Ryazan district of Ryazan region and involved 12 fresh black-and-white cows aged 4 years. The control group of animals was intact. As a result of the investigations, it was found that due to the action of the above preparations, which have antioxidant properties, the productivity parameters in the experimental groups of animals were higher compared to the control group, because they had an inhibiting effect on lipid peroxidation processes in the organism and activated the work of its own antioxidant system.

Because of the increasing trend in globalization in dairy farming resulting in joining and taking over some companies with the aim of rationalization of production and realizing greater market participation, it seems quite real to expect such a trend to appear in our country as well. After the process of privatization had been realized a significant part of Montenegrin economy fell into the hands of private owners. In such conditions it can be expected that efficiency and competitiveness of some producers of milk and dairy products in the Republic of Montenegro will be increased, since in previous period this industry was characterized by insufficient exploitation of already existing capacities for milk processing while the quality of milk was considerably under the standards prescribed by the European Union. Depending on the dynamics of entering Montenegro into international economy the national dairy industry must be ready to face the challenge which will certainly be imposed on it. The object of this paper was to try to find the answers to the two questions. First where we are now and where we will be in the next five years in order to improve the competitive potential of domestic dairy farming.

Poultry farming is one of the major branches of animal husbandry, which develops through concentration, specialization and intensification on the basis of poultry plants and poultry farms. The increase in production of eggs and poultry meat is based on a significant increase in the productivity of poultry with a simultaneous increase in its population with a high payment of feed by production and the increase in labour productivity. The purpose of the work was to study the influence of enzyme feed additives in the diets of laying hens on the quality of eggs. The researches have been carried out in PJSC “Poultry plant Chelyabinskaya”, which produces high-quality chicken eggs obtained from the poultry cross “Loman LSL-classic”. The object of study was enzyme drugs produced by Sunzyme – a multi-enzyme drug that includes xylanase, cellulase and mannase activities. The dosage of enzyme drugs in the feed mixture of laying hens was: Sunfyze 5000 – 80 g/t, Sunzyme – 100 g/t. The results of researches show that in the groups that received enzyme drugs in their diet, egg production was higher than in the control group. So, for the entire period of researches the hens of the experimental groups were significantly superior to the control group in terms of egg production per average laying hen. The largest difference was in hens of the 1st experimental group (enzyme drug Sunfyze) – 10,8 eggs; the smallest in hens of the 3rd group (enzyme drugs Sunfyze and Sunzyme) – 5,7 eggs. In hens of the 2nd experimental group compared with hens of the control group egg production was higher by 7,9 eggs. The best indicators of production efficiency have been obtained in the 1st experimental group of laying hens, which were fed with the enzyme feed additive Sunfyze to reduce the nutritional value of the diet according to the matrix.

Promising in feed production is the preparation of haylage with subsequent storage of herbage together with preservatives. The modern market off ers various chemical preservatives in the form of organic acids: propionic, formic, benzoic and their salts. Some disadvantages of preservatives of this group (volatility, toxicity, venom, ability to cause respiratory burns, corrosion, etc.) require to organize a search for new ones based on bacteria and enzymes. The purpose of the work was to increase the level of milk productivity of cows and quality of milk by using the preservatives Biosib and Silostan in the preparation of haylage. Scientifi c and economic experiment has been carried out in LLC “Agrofi rma Bairamgul” in the Uchalinsky area in the Republic of Bashkortostan. For the research, 36 Holstein cows have been selected, from which 3 groups of animals have been formed based on the principle of analogues per 12 heads in each. The input in the ration of lactating cows of grain and legume haylage prepared using the technology with the use of preservatives Biosib and Silostan contributes to the increase in milk productivity. The best eff ect has been demonstrated when using the drug Silostan (the 2nd experimental group), which can be explained by the diverse biological composition of microbes, as well as amino acid complexes, enzymes, vitamins and trace elements. The increase in milk productivity of cows of the 1st and 2nd experimental groups allows to reduce the prime cost of production, respectively according to groups, by 38,7 rubles or 3,31 % and 51,1 rubles or 4,43 %; to increase revenue from the sale of milk by 3186,5 rubles or 4,32 % and 3664,0 rubles or 7,24 %; net profi t by 1791,9 rubles or 17,97 % and 2570,6 rubles or 25,78 % and the level of profi tability by 4,14 and 5,52 % compared to the control group.

This review attempts to reflect the importance of different factors that affect the environmental quality of dairy farms and must, therefore, be taken into account when considering the importance of environmental microbiology as a tool in the improvement of the quality of milk and dairy products. The effect of a factor such as temperature is vital for the dairy farm environment, especially when the temperatures are extreme, because a proper choice of temperature range improves the quality of the air and, thus, animal welfare. Similarly, the appropriate level of relative humidity in the environment should be taken into consideration to avoid the proliferation of microorganisms on the farm. Air quality, well-designed livestock housing, proper hygienic practices on the farm, stocking density, and the materials used in the livestock houses are all important factors in the concentration of microorganisms in the environment, promoting better welfare for the animals. In addition, a ventilation system is required to prevent the pollution of the farm environment. It is demonstrated that proper ventilation reduces the microbial load of the environment of dairy farms, enhancing the quality of the air and, therefore, the wellbeing of the animals. All this information is very useful to establish certain standards on dairy farms to improve the quality of the environment and, thereby, achieve better quality milk and dairy products.

<p>The contamination of raw milk with psychrotrophic micro-organisms has become a concern because they are able to multiply at refrigeration temperatures and produce heat resistant enzymes that affect the quality of milk and dairy products. The objective of this study was to evaluate the effect of acidification with CO<sub>2</sub> and HCl on mesophilic and psychrotrophic bacteria present in raw milk during cold storage. Raw milk samples were acidified with CO<sub>2</sub> and HCl 1N until pH 6,0 and stored at 5 &deg;C for 10 days. The results showed an average reduction of 1 logarithmic cycle in the growth of psychrotrophic and mesophilic microorganisms in samples treated with CO<sub>2</sub>. Acidification with HCl showed no effect, indicating that inhibitory action was due to CO<sub>2</sub> not by pH reduction.</p><p>&nbsp;</p><p>DOI: http://dx.doi.org/10.14685/rebrapa.v2i2.68</p>
