Goal. To determine the economic efficiency of sanitation of milking and dairy equipment with the use of new detergents Sanimol L and Sanimol K. Methods. General scientific methods are used: analysis and synthesis, comparison, and theoretical generalization. A direct calculation of the difference in the cost of similar funds is also made. Results. It is determined that the total estimated economic effect per 100 lactating cows during sanitation of 5 portable milking machines three times a day and milk cooler once a day with Sanimol L and Sanimol K during the year will be UAH 21,097 compared to CircoSuper AF and Sidmax. The economic effect obtained due to the increase of microbiological indicators of milk quality as a result of sanitary treatment of milking equipment with Sanimol L and Sanimol K is calculated for 100 cows for 3 times milking with portable milking machines. The milk yield for one lactating cow was 4,500 kg/ year. Before the introduction of sanitary treatment of milking equipment with Sanimol L and Sanimol K, the farm received the grade I milk which worth 8.4 UAH/kg. The use of these preparations made it possible to obtain and deliver milk to the processing plant of the extra grade for 9.8 UAH/kg. Annual economic effect -- UAH 624097.2. Conclusions. The use of Sanimol L for sanitary treatment of milking equipment is 1.3 - 1.8 times more cost-effective compared to CircoSuper AF, and Sanimol K -- 3.8 - 4 times more than Sidmax. The annual economic effect due to the use of Sanimol L and Sanimol K for sanitation of milking equipment and dairy equipment on dairy farms with a population of 100 cows will amount to UAH 624097.2.

Key words: cost calculation, costs, microbiological indicators, milk grade.

Upon receipt of milk basic source of its microbial contamination is insufficiently cleaned milking equipment [1]. The remains of milk and water for rinsing on internal surfaces milking and dairy equipment support the development of microorganisms [2]. Insufficient cleaning and disinfection of milking and dairy equipment allows microorganisms remain, reproduce and grow on their internal surfaces. This results to increase of number of microorganisms in milk [3]. An important condition for receipt of milk of sort extra is the use to sanitizing milking equipment of cleaning- disinfecting agents providing its proper cleanliness in accord with uniform norm with numbers of microbes of wash off up to 500 CFU/cm³ [4]. At the same time besides ensuring the normative cleanliness of milking and dairy equipment cleaning-disinfecting agents must have such competitive advantages as: ecological safety and a little lower cost compared with analogical products. Taking this into account, determination of economic efficiency use cleaning-disinfecting agents to sanitizing milking equipment is one of the important tasks.

Analysis of recent research and publications. Creating of cleaning-disinfecting agents to sanitizing of milking and dairy equipment were engaged in A.G. Khramtsov [5], J. Berard [6], F. Gelmi [7] et al. Questions related to assessment of effectiveness of cleaning-disinfecting agents to sanitizing of milking equipment reflected in the study of such scientists as: N.N. Laushkina [8], M.M. Karpenya [9], M.A. Sergeeva [10], A.R. Monken [11] et al. However, in scientific literature enough little attention is paid to such question, as determination of economic efficiency of using of cleaning-disinfecting agents to sanitizing of milking equipment.

Goal of researches. Determination of economic efficiency of sanitizing of milking and dairy equipment at application of new cleaning-disinfecting agents Sanimol L and Sanimol K.

Expenses on sanitizing of milk cooler is 12.5 hrivnas and 50.0 hrivnas. Expenses on sanitizing of milk cooler throughout the year is 4562.5 hrivnas and 18250.0 hrivnas. Economic efficiency is 13687.5 hrivnas.

Thus, the general supposed economic effect on 100 lactating cows when sanitizing of five portable milking machines three times per day and milk cooler once a day agent of Sanimol K in a year will be 17739.0 hrivnas.

Economic efficiency of application of agents Sanimol L and Sanimol K was calculated on 100 cows at three times milking by portable milking machines. Milk yield per lactating cow was 4500 kg per year. On the farm before the introduction of sanitizing of milking and dairy equipment by agents of Sanimol L and Sanimol K received milk first class by a cost a 8.4 hrivnas per 1 kg. The use of these agents allowed to get and deliver milk to the processing plant sort extra, at a cost of 1 kg - 9.8 hrivnas.

The economic effect a consequence of improved microbiological indicators of quality of freshly milked milk as a result of realization of sanitizing of milking equipment agents of Sanimol L and Sanimol K (Es) was calculated according to the formula:

Es = Qm x (P, - P₂) - Es (1)

where: Qm - quantity of freshly milked milk of sort extra, (kg);

Pi and P2 - prices on realization obtained of milk extra and first sorts respectively, (hrivnas);

Es - expenses on realization of sanitizing of milking machines, milk containers and milk cooler, (hrivnas).

Es = 450000.0 x (9.8 - 8.4) - 5902.8 = 624097.2 hrivnas.

The annual economic effect as the result of using agents of Sanimol L and Sanimol K to sanitize of milking and dairy equipment on dairy farms with number of 100 cows will be 624097.2 hrivnas.
