This article highlights the data showing the different levels of efficiency of mixed lygand Zinc complex to obtain clean milk from highly productive Holstein cows from Germany. Tested cows were fed during the experiment with small component forage mixture composed of concentrated feed-sulfate salts of copper, cobalt, manganese, sodium selenite, forage mixture to complement these micronutrients to normal, and selenium concentration which was adjusted to 0. 3 mg / kg dry matter intake and depending on the circuit experiment, to different doses of mixed lygand Zinc complex. Control Holstein cows were Hungarian, in compound feed, concentrates which was mixed lygand complex of zinc, zinc deficiency is covered by 50%. Cows from the research groups from Germany – zinc deficiency covered 85, 70, 55 and 40% by mixed lygand Zinc Complex
Based on data obtained during the scientific and economic experiment, it was found that the elimination of zinc deficiency in the forage mixture of 70% by mixed lygand complex of zinc in the diets of dairy cows from the breed ‘Holstein’ from Germany in the dry period and the first 100 days of lactation, provided that one insemination each cow in the 1st control group it took 2,3 fertilization in the 2nd-0 2. 2; 3rd – 1. 5; 4th – 1. 9 and 5th – 2. 1 and reduce the length of service period. Thus, in the the cows from the 1st control group this period lasted in the average of 89. 2 days in the 2nd – 78. 6; in 3rd – 75. 4; 4 th -84. 6 and -95. 5 5 days, which in percentage terms compared with the animals of the 1st control group, except for the 5th research group at: 11. 88 in 2- and, 15. 47 in the 3rd and 5. 16 in the 4th, and 5 more at 7. 06.
Based on data obtained during the scientific and economic experiment it was proved that genetic potential of highly productive cows of Holstein breed of German selection in forest-steppe zone of Ukraine is best realized to the elimination of zinc deficiency by 70% through the use of mixed lygand complex of this element.

Because of their high growth rate, factory chickens are sensitive to necessary nutrients, mineral and biologically active substances. It is extremely important for them to have a balanced diet, particularly at an early age, in the first and second weeks of their life, when a chicken has not quite adapted to the environment, and is thrown to the influence of various stress factors. As is well known, the enzymatic system in the digestive tract in chickens is formed within 7-10 days. Whilst getting a significant proportion of nutrients and energy from the rest of yolk in the first 2-3 days. Therefore, in this period the rations for factory chickens must contain easily digestible nutrients, and feed ingredients must be chopped to a particle size of 0. 9-0. 12 mm in diameter. For this experiment, in the poultry house 500 heads of factory chickens were chosen, which were divided into 5 groups of 100 heads each. Starting from the first day, the chickens of the 1st (control) group were fed with an adequate combination feed and the poultry of the 2nd,3rd,4th,5th experimental groups got the same combined feed, but during the first 7 days with the mass particle of NuPro preparation, respectively – 1,2,3,4% in it. The results of the experiment showed that the introduction of the combined feed of 1-4% of mass particle of NuPro improved a rate of growth of experimental broilers. If the average daily weight gain for the 1st week in the control chickens was 21. 7 grams, then in their analogues of the 2, 3, 4 and 5th experimental groups it was by 6. 8; 8. 7; 7. 3 and 4. 2% more. The body weight of factory chickens of the 2nd-4th research groups in 42-day age and was also higher and amounted 2622. 8-2764. 1 against 2534. 8 g in control, – with a simultaneous reduction in the amount of growth by 1. 1-2. 2%. Inclusion of NuPro in the feed in the first week of factory chickens life increases the potential for improving of digestibility of nutrients, nitrogen fixation and mineral elements that appears to increase the growth intensity of poultry throughout the whole growing period; According to the overall assessment of the results of the experiment, the optimal dose of NuPro in the combined feed is 20 kg/t.

Key words: productivity, broiler chickens, doses, time of feeding, live weight, NuPro.

An analysis of the parameters of technological operations to make hard cheeses in the second heating, the improvement of the technology of making the elite hard cheese using concentrate of whey proteins.
Cheese can be made only from milk suitable for cheese-making which meets the official regulations.
The suitability of milk for making cheese is determined by feeds for cows. These experiments show that if cows’ feed contain many similar concentrates, the quality of cheese made of such cows’ milk is worse. Therefore cows should not be fed with one type of concentrate feeds which constitutes 20–30% of the daily norm. Feeding cows with a lot of corn feeds (such as grass, grain and silage) has a positive effect on the quality of milk and makes it possible to make high quality cheeses.
Milk microflora, including lactic and propionic acid bacteria, are useful for making cheese. Colon bacillus are harmful and dangerous in cheese-making. The quantity of microflora in milk is checked with reductase probes and the quality is checked by rennet-fermentation probes. Aseptic milk or raw milk contaminated with microbes, and also milk with disease-causing microbes is not suitable for cheese-making.
In normal cheese making processes, before fermentation, milk must contain a sufficient number of lactic bacteria – streptococcus and bacillus. The quantity of this microflora in milk determines the degree of its maturity and suitability for cheese-making.
The maturity of milk is also determined by the state of salts, namely calcium phosphate. In fresh raw milk these salts are in the colloidal state, that causes milk sedimentation and clotting. Thus fresh raw milk is considered to be unsuitable for cheese-making.
Using a concentrate of whey proteins allows for an increase in the number of cheeses by 53. 3 or 10 heads daily. similarly enterprises can earn 35241. 7 UAH implementing this technology and 37648. 9 UAH applying an improved technology. The profitability level is 8. 27% and 15. 66% respectively.
Thus, improving the technology of making hard cheeses increases production profitability on the whole, that will lead to improved results of the enterprise.

Key words: bacteria, yeast, casein, cheese-making.

The epizootological situation regarding to visceral mycosis of animals in Сentral region of Ukraine.

This article presents the results of mycological and toxicological research into the pathological material taken from poultry and domestic animals in Central region of Ukraine (Poltava region). Mycobiota, isolated from the samples was discovered to be fungi of genuses Aspergillus, Mucor, Candida as a monoinfection and others. The main part of isolated fungi accounted by micromycetes of genus Aspergillus, was identified in 28 of 43 samples (65% of all positive research). In particular, species A. flavus and A. fumigatus were found more often (40% and 23 positive results, respectively). As a monoinfection fungi of genus Aspergillus was found in 25 samples (58%). With regard to fungi from the Mucoraceaed family, growths of this sort were found in 14 samples of pathological material, that is 33% of all positive mycological research. In 7 samples was evidense of the causative agent of mucormycosis , (16% from all positive researches), In 3 samples – the causative agents of aspergillosis and mucormycosis (7% from all positive samples). The fungi of genus Candidа was identified in 12% of all positive research, and the causative agent of mucormycosis – 1 sample (2%). Also in a single sample was detected fungi Penicillium and Helmintosporium in association with micromycetes – Mucoraceae. Each find accounted for 2% of all positive results of corpses mycological research. Of all causative agents of mucormycosis the most often identified fungi -Mucor – was found in 7 lung samples from poultry(16% of all positive results). These include the fungi Mucor ramosissimus, M. racemosus, M. pusillus. The fungi Rhizomucor, Rhizomucor pusillus in particular was found in 3 samples (7% of all positive results). The raresrt fungi from family Mucoraceae was detected; fungi of genus Rhizopus, Rhizopus microsporus – in 2 samples, that is 5% from all positive research. The independent allocation of isolates fungi from the family Mucoraceae of pathological material at negative results of bacteriological researches gives us cause to considered  mucormycosisas as a cause of death of the studied birds and animals. The results showed, that most often fungi from family Mucoraceae isolated in association with aspergills and less often with fungi of the genus Candida. That confirms the possibility of associated course of mucormycosis with aspergillosis or candidosis.

The article presents the results of influence of mineral and drug Supokorrn feed phytoadditives Fitopunk on the prevention of metabolic process of gestating sows. At the end of gestation of the sows there were recorded significant violations of metabolism and reduced resistance of the organism. This had provoked subclinical ketosis, anemia, osteodystrophy, palmerosa and other disabilities that can affect the development of the fruit and the quality of offspring. When using these drugs the number of red blood cells had increased and there was found about 28,15%, white blood cells and hemoglobin 24,76% and 18,09% times compared to the control group sows. The decrease in total blood protein by nearly 10%, while the level of albumin had decreased by 5% reducing by 37,34% times urea in blood plasma of sows. It can explain the complex influence of the drug Sapokorm phytoadditives and the metabolism of protein and overall protein metabolism. Increase of total calcium 42,85% plasma gestation sows, increase of calcium-phosphorus ratio, which was 0,95:1,0 and increase of phagocytic activity indicators suggested effective provision of nonspecific host defense gestation sows. Indicators of phagocytic activity of blood neutrophils were higher in gestating sows of the experimental group 46,42% and phagocytic index of 30.11% as compared with the control, this indicates the effective provision of nonspecific protection of the organism gestating sows. The obtained data testified to positive influence of biogenic compounds of macro – and micronutrients, as lactato cobalt, copper and iron, which are part of the drug Supakorn and phytoadditives on the processes of hematopoiesis in the body of pregnant sows. Consequently, the use of Supokorm and phytoadditives Fitopunk had a positive effect on metabolic processes in the body gestating sows, which is confirmed by hematological and immunological study

Key words: sows, mineral preparation Supokorm, feed phytoadditives Fitopunk, morphological, biochemical, immunological study of blood.
