ACCLIMATIZATION OF HOLSTEIN BLACKAND-WHITE CATTLE IMPORTED FROM DIFFERENT COUNTRIES IN THE CENTRAL NONBLACK SOIL AREA OF RUSSIA

abstract 1211607030 issue 121 pp. 609 – 619 30.09.2016 ru 653
The article presents a study of acclimatization characteristics and the effectiveness in the use of Holstein black-and-white cattle imported from Germany, Denmark and the USA under the conditions of the Central Non-Black Soil Area of Russia. The analysis shows that the imported animals are exposed to a number of stress factors that often cause the diseases and serious losses of cattle. The main reasons for the losses of heifers were the pathologies of the reproductive organs and the mammary gland (26,3%), locomotor system and distal extremities (15%), respiratory organs (21,2%), etc. The highest-producing dairy cows were those imported from the USA (9158 kg of milk throughout the first lactation). For the yield of milk, they are superior to animals imported from Germany in 1828 kg (P≥0,999) and those imported from Denmark in 1184 kg (P≥0,999). The average American Holsteins’ milk over a 305-day lactation is higher in fat (4,14%) than that of their German (in 0,28%) and Danish (in 0,21%) counterparts (P≥0,999). The same tendency is observed in the protein content in the milk

ROLE OF PUMPKIN FLOUR IN FORMATION OF QUALITY OF WAFERS

abstract 1211607038 issue 121 pp. 708 – 718 30.09.2016 ru 801
To study the effect of pumpkin flour on the physical and chemical parameters of semi-finished and finished products, 10, 15, 20 % of the weight of wheat flour in the dough was incorporated to the dough mass. As a result of the research and the analysis of wafers with different PF dosages, the dosage of 15 % pumpkin seed flour from the wheat flour mass in the dough was accepted as the optimum one. After selecting the optimum dosage, the experiment on identifying the dependence of dough viscosity on the shear rate was carried out. The samples were taken without adding PF into dough and with adding PF for 15% from the weight of the flour in the dough. The results showed that the viscosity of the control dough sample was higher than that with 15% of flour from pumpkin seeds. This is due to the general decrease of the amount of swellable proteins in the dough due to the incorporation of PF. Thus, we can conclude that the introduction of the investigated additive into the wafer dough does not obstruct dosing the semifinished product into the wafer moulds. The analysis of the obtained data as a result of the research work has shown that incorporating pumpkin seeds flour into the recipe of wafers is expedient both in terms of enriching the product with proteins, fats and biologically active substances and in terms of improving the process in the production

abstract 1211607048 issue 121 pp. 835 – 845 30.09.2016 ru 391
Nicotiana tabacum and rustica are facultative self-pollinated plants, therefore, because of pollination peculiarities, specific methods are applicable to growing seeds of this plants. Researches on mass, individual and family, recurrent methods of seeds selection for productivity and sowing properties are carried in the institute for revealing most efficient methods of getting seeds. Seeds growing system for Nicotiana tabacum and rustica is a part of general seeds growing system for all agricultural plants and consists of breeding, testing new sorts, mass reproduction of seeds with retained biological and productivity properties, seeds harvesting and controlling their sort and sowing properties. Primary growing of nicotiana tabacum and rustica seeds is carried by individual and family or recurrent selection and further testing of chosen plants, distinctive for this sort, on economically valuable and biological properties. Peculiarities of each zoned sort are kept by retaining its primary genome with constant selection of highly productive genotypes, specific for this sort. Well-organized seed growing system leads to sort potential revealing. Biotype composition of sort is obviously changing in a few years, so primary seeds growing system should be constantly improved

ASSESSMENT OF AGROMETEOROLOGICAL FACTORS ON YIELD OF PEACH CULTIVARS IN RUSSIAN HUMID SUBPROPICS USING MATHEMATICAL MODELING METHOD

abstract 1211607049 issue 121 pp. 846 – 859 30.09.2016 ru 532
Peach fruit is much demanded worldwide. The success of its cultivation depends on the optimal plant placement of all the huge biodiversity considering the cultivar demands. The northern boundary of the peach cultivation passes through the Kiev-Kharkov-Rostov-on-Don, Maikop, Nalchik, Grozny, Astrakhan (Witkowski, 2003). However, because of extreme temperatures there are almost no suitable areas for Peach crop cultivation in these borderlands, in the Krasnodar and the Stavropol regions. From the other hand, extreme temperatures for peach cultivation in the humid Russian subtropics were not observed. Spring frosts till -5 ° C were observed in 2004, 2014. However, the cultivar productivity in the region influenced by the duration of low temperatures (7,2 ° C and below) that were observed from December to March. The amount of low temperatures for each cultivar was established using the highest coefficient of yield determination, depending on the temperature, amount of precipitation and the "cooling unit." The yield of peach cultivars is closely linked with the abovementioned agro-climatic conditions during the flowering period. Paired correlation coefficients of yield with precipitation and with temperatures (for most cultivars) were negative, and since they are unregulated value, the flowering phase is crucial for peach culture in the Russian subtropics

USAGE OF SEEDLINGS FOR RECEIVING ULTRAEARLY HARVESTS OF POTATO

abstract 1211607084 issue 121 pp. 1359 – 1368 30.09.2016 ru 412
Using of seedling method for growing early potatoes accelerates the starting processes of growth and development of plants, and the application of temporary covers of the nonwoven covering materials protects the landing from sudden temperature changes and relapsing frost. To receive seedlings of early potatoes we used standard seed tubers of 60-80 g weigh of the following varieties: Agata, Red Scarlett, Kislovodskiy, Vershininskiy and Sheri. By the time of planting in the ground, depending on the varieties, the height of seedling was from 13 to 26 cm, the number of leaves - 7-10 pieces. Conducting of trial unearthing of potato showed that on 45 days after transplanting into the ground (the second decade of May), it is possible to receive up to 10, 5-11, 4 t/ha (Agata and Red Scarlett varieties). On 55 days (the third decade of May), the yield reached 26, 4 t/ha of standard tubers, and in the first decade of June the yield was from 26, 4 to 50, 6 t/ha. The maximum yield of standard tubers of 50, 6 t/ha was obtained by lifting on 65 days with the Red Scarlett variety. In the terms of the Astrakhan region the growing of early potato by seedling method with using of temporary cover allows to receive the ultra-early harvest of marketable tubers in the II-III decade of May

EFFECT OF FATTY-ACID CONCENTRATE (FAC) AND CARNITINE ON PERFORMANCE, PHYSIOLOGICAL CONDITION AND MEAT QUALITY OF BROILER CHICKENS

abstract 1211607089 issue 121 pp. 1453 – 1472 30.09.2016 ru 482
An experiment was conducted to examine the effect of fatty acid concentrate (FAC), as a new source of energy and carnitine on performance, physiological condition and meat quality of broiler chickens. In experiment there were four groups of 80 chickens of cross Hubbard each (males: females=40:40) in age period 0-41 days. 1 group (control) received in during the periods 0-14, 15-28 and 29-41days, sunflower oil (SO) respectively 5.34%, 5.50%, and 6.10%, group 2 received the same amounts of FAC instead SO, 3 group - mixture SO:FAC (50:50), 4 group -FAC + 0,25% carnitine. Final body weight: 1 group = 2574±29 g, 2 group FAC= 2553±27 g 3 group SO + FAC = 2531±34 g., 4 group FAC+0,25 carnitine = 2520±34 g. Feed conversion, digestibility of nutrients, blood hematology and biochemistry, the condition of organs, meat quality and cutting of carcass of chickens on FAC had no any differences from the same signs in chicks on SO. Carnitine had a positive effect on chicken growth only in the period 0-14 and less 15-28 days; in the period 29-41 days daily gain was below, than that in 1-3 groups. Canitine reduced the content of liver fat. Outcome: FAC is a satisfactory source of energy, comparable with vegetable oils. The price of FAC is 30% lower in comparison with sunflower oil and soybean oils, therefore its use in broiler poultry farming instead of vegetable oils will be of great economic importance
