World experience shows that family farms are the basis for the agricultural sector of countries with advanced market economies. The analysis of the components of the livestock ration provided an opportunity to identify the amount of feed mixture, which needs to be distributed to animals per day, depending on the livestock. Researches have shown that for preparation and distribution of feed on farms with livestock up to 10 cattles, it is advisable to use inefficient machinery with energy drive and partial execution of manual operations, 11-35 -self-feeders, mechanized lines using stationary machinery with energy drive and forklifts. For 36-50 cattles of livestock and at an average animal productivity of at least 6500 kg of milk per year, processes of preparation and distribution of feed can provide self-feeding and mobile combined feed making machines. Preparation and distribution of feed mixes for 51-400 heads of cattle -provide mobile combined feed making machines with delivery of the mixture on the feed tables. For livestock with more than 400 heads of cattles, it is advisable to use stationary robotic feed making facilities and distributors of feed mixtures or a mobile combined feed making machine. In the feed mixture preparation process, it was found that the multifunctional feed making machines with a vertically positioned conical auger in the hopper have a high power consumption of more than 35 kW. Power consumption, driven by the working bodies, is almost directly proportional to the speed of an auger. With increasing rotation frequency of an auger, the efficiency of grinding and mixing does not increase significantly; we have substantiated the rotation frequency of an auger 16-20 min -1 , with grinding rolls and packs and in the mode of mixing and dispensing 24-25 min -1 . However, in the process of dispensing the feed mixture, the existing auger does not clean itself from the feed.
Recently, the requirements for the quality and safety of poultry products have significantly increased, what has notably limited the use of antibiotics in feeding poultry. This is one of the reasons for the growing interest in the use of phytogenic feed additives. We have conducted an experiment to determine the influence of Artemisia capillaris on young quail meat productivity. To carry out the experiment, we have formed five groups, each counting 100 quail heads. During the experiment, which lasted for 35 days, dried powdered wormwood (Artemisia capillaris) in the amount of 0.5%, 1.0 and 1.5% by weight of compound feed was introduced into the feed of birds of the 2 nd , 3 rd and 4 th experimental groups. The experiment showed a positive effect of the studied factor on the body weight of quail; the highest body weight was in quail of the 3 rd group -251.03 g, and the lowest it was in the control group -238.24 g. Also during the experiment, the lowest feed costs per 1 kg of body weight gain were in quail of the 3 rd experimental group, which by this indicator exceeded the control group by 4.91%. Feeding wormwood as a part of the compound feed in the amount of 0.5 and 1.0% of the 2 nd and 3 rd experimental groups increased the weight of gutted carcass by 0.41-1.67%, while further increase of wormwood content to 1.5% in the feed of the 4 th experimental group led to a decrease in the weight of gutted carcass by 0.26% compared to the control group.
Ibatullin, I.I., Holubiev, M.I., Otchenashko, V.V., & Makhno, K.I. (2018). Productive qualities of ducklings with different normalization methods trace elements in the diet.In the article, results of researches on an establishment of an optimum source of Manganese, Zinc, Iron and Copper are resulted. Different source Manganese, Zinc, Iron and Copper was additionally added mixed fodder for ducklings grown for meat. Experimental studies conducted in terms of problem research laboratory of feed additives National University of Life and Environmental Sciences of Ukraine. Independent experiment was conducted with growing meat ducklings. We conducted a randomized block experiment with 5 treatments, each with 4 replicates of 25 growing ducks (1 to 42 d of age). A diet consisting of corn, soybean and sunflower meal, fish meal, premix (22.5% CP, 2.92 kcal of ME/g on 1 to 14 d of age, 18.5% CP, 2.90 kcal of ME/g on 15 to 42 d of age) having severally Manganese, Zinc, Iron, Copper at sulphate, glycinate and citrate. The premix was formulated to contain the requirements of trace elements in combination of either inorganic (sulphate form) or organic form (glycinate and citrate form). Diets were supplemented with the organic form of zinc, copper, manganese or iron at the rate of 100% or 75% of the total requirements of the elements. Diets and water were offered ad libitum. After 6 weeks of dietary treatments the growth performance (feed intake, body weight, daily gain, feed conversion, homogeneity of the poultry) were affected by dietary treatments. Results indicated that chicks fed diets containing 100% organic minerals (Mn, Zn, Fe, Cu) had significantly higher body weight, better feed conversion compared with those of inorganic control minerals treatment. Use of fodder for ducklings, which are grown for meat glycinate Mn, Zn, Fe, Cu versus sulfate improves their productive performance. The body weight of ducklings at 42 d of age is more by 1.6% (P < 0.05) and the conversion of feed is 1.0% higher. The conversion of feed from consumption was rather high (R 2 =0.84), which confirms the change in the productive indicators of duckling from the feed factor.

The effect of phytobiotic additive – dry wormwood powder Artemisia Capillaris on the meat productivity of young quail was studied. The efficiency of different levels of additives in compound feed – 0.5-1.5% was studied. The most effective level of dry wormwood powder in the feed of young quails –1.0%. With the addition of this amount of Artemisia capillaris in the feed of young quail meat productivity, live weight increases by 5.37% (Р <0.05); absolute increase – by 5.60% (P<0.05); average daily increase – by 6.78% (P<0.001) and relative increase – by 146.52% (P<0.001); feed costs per 1 kg increase are reduced by 4.91%; the weight of unharvested, semi-gutted and gutted carcass increases by 5.94 (P<0.01), respectively; 6.53 (P<0.01) and 7.84% (P<0.01); the mass of the pectoral muscles and pelvic muscles increases by 19.95 (P<0.001) and 15.89% (P<0.01), respectively. The introduction of 0.5% dry wormwood powder in the feed of young quail causes an increase in live weight of birds by 3.32% (P<0.05), absolute, average daily and relative gains, respectively, by 3.45 (P<0.05 ), 3.39 (P<0.01) and 75.38% (P<0.001), reduction of feed costs per 1 kg increase – by 3.60%, increase in the weight of uncoupled, semi-gutted and gutted carcasses, respectively by 3.48 (P<0.05), 3.61 (P<0.01) and 4.28% (P<0.05), chest muscle mass – by 11.59% (P<0.01) and pelvic limb muscle – by 6,98% (P <0.05). A further increase in the level of dry wormwood powder in the feed of young quails to 1.5% led to a certain decrease in meat productivity compared to counterparts consuming feed with Artemisia capillaris content of 0.5-1.0%. However, compared to the control indicators of growth and meat productivity were higher. Different levels of dry wormwood powder in the feed did not significantly affect the weight of the skin, liver, kidneys, muscular stomach and heart, as well as the preservation of quail, which was at a high level – 94-95%.
