(ехінацеї пурпурової, елеутерококу, полину, буркуну, валеріани, шипшини, калга-ну, родіоли) (carotenoids, ocimene, pinene, sabinene, thymol, citral, lynalool, terpinene) have been shown.At watering the eucalyptus leaves infusion 1.2 ml/day the laying hens performance increases by 1,74 % (89,28 % compared to 87,54 % in control). However, the poultry egg production was higher (6-9 %) at using the phytopreparation during the first four weeks of the experiment. The literature data show that the introduction of 10 % celandine tincture to quails diet (0.07 ml/kg body weight) leads to rising birds weight in 0,9-1,5 % compared to control. The forage nutrients transformation to quails production increases because the celandine contains alkaloids flavonoids, saponins, carotene, vitamin C, etc. The application of feed additives from unconventional vegetable raw materials (Echinacea purpurea, eleutherococcus, sage, sweet clover, valerian, wild rose, kalgan, rhodiola) 3,9-4,1 % and laying hens -in 5,2-28,8 %.

The paper presents a fragment of a systemic study on the efficiency of replacing inorganic salts of microelements in guaranteed mineral premixes used in quail feed with a complex supplement of said elements in nanocitrate form produced by Nanomaterials and Nanotechnologies LLC (Kyiv). The study is, in particular, focused on the levels of microelements (Mn, Zn, Cu, Fe, Co, І) in quails and their egg yolks depending on the form and concentration of those microelements in the poultry diet. The tests have been conducted on 14-day old Pharaoh quails divided into three groups. Raising conditions – cages. Test duration – 2 months. Quails of all groups were fed complete feed with a balanced content of nutrients and biologically active compounds. Control group birds were given mineral premix containing inorganic salts of (g/t of feed): Mn – 50, Zn ‒ 50, Cu ‒ 2.5, Fe ‒10, Co ‒1 and І ‒ 0.7. Test group quails were fed a mineral complex of aqua citrates of the same elements with a concentration of (calculated for each element) 1/10 (D1) and 1/20 (D2) or 10 and 5 % of their content in a standard mineral premix (SP). It is established that the form and dosage of microelements introduced into the diet affect their levels in quails and their egg yolks. Nanocitrates of bioelements have a relatively high cumulative potential in poultry compared with the control group (an inorganic form of microelements). The best results are achieved with citrate elements being fed in a concentration of 10% of their regular content in a standard mineral premix. It is proven that the use of optimal concentration of aqua citrates of microelements in poultry diet promotes increased levels of manganese, iron, zinc, copper and cobalt (Р < 0.05‒0.001) in the liver and hip muscles as well as iron and copper levels (Р < 0.01‒0.001) in breast muscles of quails; increased body weight by 15.7 % during the testing period; an enhanced biological value of the eggs (increased calcium (Р < 0.05), iodine (Р < 0.05), zinc (Р < 0.01) levels) compared to analogs in the control group.

Egg production characterizes not only the economic efficiency of the poultry industry, but also the effect of various factors that contribute to the realization of the genetic potential in modern high-yielding breeds, crosses and lines, or suppress its processes. These factors include nutrition, which should take into account diet balancing according to certain nutrients, as well as their qualitative indicators. Nowadays on the feed market for farm animals there are the products characterized not only by a high protein content, but also by a high digestibility. Among others, a new innovative product — a sunflower concentrate “Proglot” developed by specialists of the “Potoky” Dnipro plant is noteworthy. According to the developers, in its manufacturing a unique nanotechnologies of sunflower seed processing were used — low-temperature extraction with maximal separation of the husk. Thus, “Proglot” can be more valuable for use in poultry feeding than high-protein soybean meal, due to the absence of “anti-nutrient” substances. The article presents the results of the study aimed to find out the productive qualities of laying hens fed a highly digestible protein with a high assimilation ratio into their diet. The experiment was conducted on the Lohmann brown breed laying hens. The control group received a compound feed containing soybean meal and sunflower meal (crude protein 17%), the 1st experimental group -— soybean meal and “Proglot” (high-protein concentrate crude protein 17%), and the 2nd experimental group — high-protein concentrate only (crude protein 15%). It was established that the replacement of soybean meal in the complex ration compound feed with the innovative product “Proglot” does not cause significant intergroup differences in the body weight of the hens during the experimental period. It was shown that the maximum increase in the proportion of digestible protein in the hens’ diet and the reduction of the fraction of protein that cannot be assimilated has a positive effect on the intensity of metabolic processes in the body of laying hens during the synthesis of egg components. At the same time, the poultry productivity increases: the indicators of laying hens of the 2nd research group exceeded the indicators of the analogues of the control and the 1st research groups by 2 and 4% (P<0.05), respectively, and the quality of the obtained products increases too — the absolute mass of egg protein (P<0.05) and shell strength (P<0.01).
