The results of studies on the effect of different precursors and technologies to the regime of organic matter and nutrients black earth southern carbonate and dark chestnut soils of Pavlodar region. In the southern black earth early rocker par with the traditional preparation technology provides an average level of NO₃ before sowing spring wheat (46.8 mg/kg), which number systematically decreases in subsequent crops, which indicates the need for nitrogen fertilizers. All studied species of vapor, used their training technology and intensification of different backgrounds do not have a significant impact on the availability of dark-brown loam soil nitrate nitrogen (N-NO₃) and mobile phosphorus. N-NO₃ content remains at a very low level-5 mg/kg in a layer 0-40 cm and at elevated P₂O₅ - 115-133 mg/kg in the 0-20 cm layer, indicating the need for a nitrogen fertilizer at higher doses.

During 2006-2015 in accordance with the methods of the national standards assessed technological and baking properties of grain of winter wheat cultivars Bezenchukskaya 380, Bezenchukskaya 616, Turquoise. A negative influence of heavy (250% to normal) moisturizing period of grain filling and high temperature (38,8 °C) in the phase of wax ripeness on the quantity and quality of gluten. The studied varieties of winter wheat in the typical meteorological conditions of the Middle Volga region stably form the grain of the first class: mass fraction of protein in grain - to 15,2-17,6%, wet gluten - to 38,9-43% of the number of drop - 401-416, nature, 818-826 g/l the potential of the rheological properties of the test exceed the standard for strong wheat: liquefaction test - 40 E. f., the formation and stability test is 13,5-17,5 minutes, calorimetrically rating - 88-98 units calorimetry. The amount of bread - 840-1125 ml with an overall score of 4,4-4,8 points. Meteorological conditions years cause high phenotypic variability of the rheological properties of the test (C_V=46,5-71,3%), the average variability of characteristics: falling number (C_V=12,2-14%), mass fraction of protein in grain (CV=9,9-12,2%), total score of bread (C_V=7,2-10,9 %), low grain (C_V=4,2-4,3%).

The greatest content of sugars was noted in Osipovskoye, Dariona, Vavilovskoye, Ivanovskoye, Orlovskiy Partizan and Patri ot. Avgusta, Radost Nadezhdy, Bezhin Lug, Orlovskiy Partizan and Patriot had the greatest content of phenolic substances. The greatest content of ascorbic acid was in Ivanovskoye, Maslovskoye, Osipovskoye and Yubilar. Aleksandr Boiko and Vavilovskoye, winter triploid varieties with immunity to scab, are of special value. Columnar varieties Vostorg, Poezia and Priokskoye have also been included in the State Register for the Central and Central-Chernozem regions. These varieties are of great interest for amateur and farm orchards because they give an opportunity to establish super intensive orchards and obtain economic yield in the third year after planting. Priokskoye is the best variety among them. Its fruit are assessed by 4,5 point for appearance and 4,4 point for taste.

The article presents the data of researches on study of influence of mineral fertilizers on the growth, development, yield and feed value of mixed crops. The aim and objectives of the research is the study of the power modes of the mixed crops of annual fodder crops for conveyor production of feeds for fattening complexes and industrial farms. The result of these tests is discovery the productivity and value of forage crops by mineral fertilizers with conveyor production. As shown by these studies, the yield of the mixed crops at harvest on forage depended on the modes of mineral nutrition. Thus the highest productivity of forage mass obtained with mineral fertilizers according to the scheme N₃₀P₃₀ autumn + N₂₀P₂₀ when seeding. Research results are relevant and find their practical application.

The researches established the expediency of moderated (65-75% browsing) use of pastures. The change of floristic structure and efficiency and also deterioration of agrochemical and agrophysical indicators of pastures soil cover is noted at the intensive use of pastures. As shown by the data on studies in the synthesis of the summer production area with a weak mode of use involves only herbs. Year high its products are almost entirely determined by the development of steppe grasses and is of 6,22 с/he, which by the end of summer is reduced almost two times (3,88 с/he). On a plot of temperate pasture production of grasses for the entire growing period was at the level of 5,22 с/he in the spring of 6.05 с/he in summer and 3,17 с/he in the fall. On the site with full use of the spring production of grass variety was greater than in other seasons of 1,44 с/he.

UzRIPI and ICARDA varieties were studied for valuable traits and drought tolerance on the rainfed conditions. It was selected the variety of durum wheat with high productivity and drought resistance on complex valuable traits.

The article presents the results of research on thoroughbred breeding of beef cattle of Auliekolskaya breed in the basic farm of the Kazakh Research Institute of Livestock and Fodder Production. With the use of plant and linear crosses, the live weight of the experimental animals exceeded the average for the herd by 6-8%. The performed studies also showed an advantage in the intensity of the growth of pedigree youngsters from the introductory crossing with the Charolais and in a comparative aspect the productivity indicators of the purebred Charolais and Auliekol bull-calves, tested according to their own productivity. The crossbreed youngsters have a tendency to increase the period of intensive growth, as well as purebred Charolais bull-calves had an advantage over this index over the analogues of the Auliekol breed.

The article presents the quality indicators of feed, fed to young pigs at growing in the conditions of industrial technology of pork production. Shown the concentration of metabolizable energy in 1 kg dry matter of feed and digestible protein. Compares the data of two experiments on the feeding of mixed fodders with different levels of inclusion in their composition smectites Tripoli and substitute skim milk, PRELAC-21. The concentration of metabolizable energy in 1 kg dry matter of feed in experiments for young pigs at growing is 15,7-14,8 per MJ. Inclusion in the composition of mixed fodders for young pigs at growing the different doses of diatomaceous earth smectitis had a positive influence on change in daily weight gain. Additive to feed 2% of diatomaceous earth smectitis weaned- piglets allowed to increase in the first experiment, the third group is 3,5% more, and in the second experiment with the introduction of 2,5% in feed composition smectitis Tripoli received an increase of 4,6% more than in the control group.

Due to the restriction import of foreign products acquires contemporary relevance of the use of domestic poultry probiotic feed additives. The article presents the results of research on testing of new domestic probiotic feed additive Basulifor in quails rearing. The introduction into the diet of experimental quails additive for 60 days at the dose 0,2 g/kg and 0,3 g/kg feed contributed significant increase in blood serum the level of immunoglobulin A in the I experimental group on 0,05 g/l (P <0,05), in II group - 0,07 g/l (P <0,05). In a similar pattern occurred an increase in the number of immunoglobulins M in serum birds both groups: growth was 7,14% and 10,71% (P <0,05). Introduction to the basic diet of quail feed additive also helped to increase the level of immunoglobulin G. Their concentration is varied at a level of 3,82±0,12 to 4,08±0,14 g/l, or 6,54- 6,8% (P <0,05). Indicators ALT in birds serum of the I experimental to 45 days of the experience as compared with analogues in the control significantly dropped off by an average of 12,4 IU/L (P<0,05), in birds of II group - 16,9 units/l (P<0,05). The level of aspartate aminotransferase in the background of the test feed additive quail in the I experimental group, compared to control counterparts dropped by an average of 17,32 U/L (P<0,05), and the II experimental group - to 15,32 units/l (P<0,05). These changes were within the physiological norm.
