COMPARATIVE EVALUATION OF THE EFFICIENCY OF SYMBIOTIC FEED SUPPLEMENT IN RATION OF LOHMANN BROWN EGG CROSS CHICKENS

abstract 1211607090 issue 121 pp. 1473 – 1486 30.09.2016 ru 482
The purpose of the research is to compare the effect of a new symbiotic feed supplement created based on propionic and lactic acid bacteria with a widely used domestic and foreign enzyme-probiotic preparations in chickens 0-28 days of age of the Lohmann Brown egg cross. In the experiment, there were six groups of chickens: group 1 received basal diet (BD); group 2 – BD + symbiotic preparation; group 3 – BD + Bacell; group 4 – BD + Agrocell; group 5 – BD + Agroksil; group 6 – BD + Ollzaym Vegpro. Average daily gain, food conversion rate per 1g of weight gain, digestibility of organic matter, crude protein, crude fiber, crude fat, made up respectively: group 1 – 8.17, 1.91, 71.4, 58.3, 68.0, 81.1; group 2 ˗ 8.36, 1.90, 72.4, 60.2, 69.7, 88.1; group 3 – 8.13, 1.91, 73.1, 60.2, 69.7, 88.1; group 4 – 8.33, 1.86, 74.2, 62.5, 72.2, 87.6; group 5 – 8.50, 1.83, 77.3, 64.1, 73.4, 95.4; group 6 – 7.91, 1.92, 73.2, 67.5, 70.7, 94.3. The growth rate of chickens fed with symbiotic feed supplement was 2.3% higher than in the control and they showed the highest fiber digestibility. The chickens on diet with Agroksil enzyme efficiently raised growth rate (+4%) and reduced feed costs (-4.2%). Agrocell increased weight gain by 2% and reduce feed costs by 2.6%. The growth rate of chickens fed Ollazaym Vegpro was the lowest (96.8% of control), despite the fact that it increased significantly the digestibility of crude protein, but slightly improved the digestibility of other nutrients. Outcome: symbiotic feed supplement may be of interest as a means of increasing the productivity of chickens

COMPARATIVE EVALUATION OF THE NUTRITIVE VALUE OF DIFFERENT VARIETIES OF PEA AND CHICKPEA GRAIN IN DROUGHT CONDITIONS

abstract 1071503092 issue 107 pp. 1416 – 1425 31.03.2015 ru 1251
The article presents materials on comparative study of the nutritional value of chickpeas and peas which are widespread in the arid zone of the Southern Urals. The scheme of the scientific and economic experiments involved the assessment of yield formation of chickpeas and peas during the vegetation. The study showed that different varieties of chickpea and pea have considerable difference in the content of nutrients. The amount of crude protein in the pea grain ranged from 25.1 to 26.8%, and chickpea – 21.7 - 22.9%. With regard to the fat, its highest concentration was in chickpea grain - 3.63%, on average, which is 1.16% higher than on average in the pea grain. The chemical composition of the pea and chickpea grain of different varieties points to differences in their composition and homogeneity within the culture. Basing on the study, we recommend to sow chickpea and pea grain in the middle of May to obtain the highest yield, this, in turn, has a positive effect on the nutritional value of the crops. When selecting plants for cultivation in the conditions of the Southern Urals, it is preferable to choose the variety of Madonna pea, which has a higher potential for yield than the chickpea variety Krasnokutsky-123. It has been experimentally found that chickpea grain has better moisture-retaining power in a bound condition during the vegetation period as compared to the relevant characteristics of pea grain, which is a positive drought-resistant value of crop. In structural elements of the harvest the peas showed the trend of the highest rates in comparison with the corresponding elements in chickpeas

COMPARATIVE STUDY OF HYBRIDS OF THE FIRST AND SECOND GENERATIONS OF DURUM WINTER WHEAT OF VARIOUS CROSS-BREEDING

abstract 1141510018 issue 114 pp. 248 – 260 30.12.2015 ru 995
The article substantiates a necessity to apply the method of interspecific hybridization in durum winter wheat breeding, using the present soft winter varieties for improvement of frost and drought tolerance at the beginning of germination; resistance to snow mold, fusariosis and bacteriosis of ears and grain. The article presents the results of a comparative study of different types of crossbreeding at interspecific and intraspecific hybridization due to germination, emergence, productivity. It has been shown that intraspecific hybrids ‘T. durum оз. х T. durum оз.’, interspecific hybrids ‘T. durum оз. х Т. аestivum оз’ and ‘Т. аestivum оз. х T. durum оз.’ possessed the highest germination and emergence with 71,8/75,3% for direct and 60,4/82,5% for backward, 42,8 and 35,5% and 55,4 and 64,1% respectively. In backward (triplecross) cross-breeding of F1 interspecific hybrids with durum winter wheat the grain germination was down to 37,4 and 36,6%, but the emergence was up to 64,1 and 69,7% and reached the level of intraspecific hybrids. According to the elements of ear (head) productivity (grain mass per head, number of seeds per head), interspecific double-cross hybrids of the first and the second generation significantly conceded to intraspecific hybrids, but they matched them in a number of spikelets and grain size. The triple-cross hybrids exceed the double interspecific hybrids in this respect, but they concede to double-cross and triple-cross intraspecific hybrids. We studied the principle of splitting of interspecific hybrids of the second generation ‘T. durum оз. х Т. аestivum оз.’ and ‘T. durum оз. х T. durum оз.’ (direct and backward) and the triple-cross hybrids obtained from cross-breeding of interspecific and intraspecific double-cross hybrids F1 with durum winter wheat

COMPLEX PROCESSING OF BEET PULP USING METHODS OF BIOTECHNOLOGY

abstract 1231609064 issue 123 pp. 917 – 929 30.11.2016 ru 499
The article analyzes the possibility of complex processing of one of the most important secondary raw materials of Krasnodar region – sugar beet pulp with the aim of obtaining a food product and enriched feed additives. Meanwhile, the use of environmentally safety technologies that cause minimal harm to the environment and human health is provided. One of the most valuable components of sugar beet pulp after extraction of sugar is pectin substance. Sugar beet pectin substances have high complexing ability and are used not only in food industry, but also in medicine. They are natural detoxifiers and antioxidants. Currently, only dry powder pectin is produced from sugar beet pulp and only by foreign producers. Making food pectin extracts from sugar beet pulp will not only reduce the number of processing steps, but also significantly reduce the cost of the final product. Food pectin extracts can be used not only as a standalone product in treatment and prophylactic nutrition, but also as an ingredient in the manufacture of soft drinks, confectionery and bakery, meat and dairy products, etc. The technology of producing a valuable component of feed bioproduct based on spent sugar beet pulp and a microscopic fungus of the genus Trichoderma is described

abstract 1061502079 issue 106 pp. 1179 – 1194 28.02.2015 ru 1001
The article contains the results of the study of mechanical composition of grapes and biochemical characteristics of white wine grapes for the production of juice of direct extraction and blending. Thus, the yield of studied grapes ranged from 7.5 to 13.2 t / ha: highest yielding varieties and hybrids of Pervenets Magaracha and Tsitronnyy Magaracha, and the lowest - Chardonnay and Pinot blanc. At an average weight of clusters of varieties were divided into three groups - large clusters (230-243 g) in varieties Pervenets Magaracha and Tsitronnyy Magaracha, medium (181-184 g) - the varieties Chardonnay and Pinot blanc, small (112-116 g) - the varieties Bianca and Viorica. By weight of the 100 berries were divided into four groups - Bianca and Viorica (I), Pervenets Magaracha (II), Chardonnay (III), Pinot blanc and Tsitronnyy Magaracha (IV). Weight of 100 seeds from the largest varieties Pinot blanc and Bianca, and the lowest - in the varieties of Tsitronnyy Magaracha and Chardonnay. The solids content in the juices of these varieties ranged from 19.4 to 21.8%, which corresponded to branded products and higher of commodity varieties. Mass concentration of sugars ranged from 18.4 to 21.3 g / 100 cm3. Titratable acid content in the juice was varied from 0.65 to 0.78 g / 100 cm3. Sugar-acid ratio, defined as the ratio of concentration of sugars and titratable acids ranged from 23.6 to 30. The recommended values for this indicator were within 22-30. According to the results of the tasting, we rated "excellent" the juices from the varieties of Tsitronnyy Magaracha, Viorica (19 points) and Bianca (17 points); "good" marks were given to the juices from Pinot blanc, Chardonnay, Pervenets Magaracha: this means that we can get juices of excellent quality from the grape varieties under study with the title of ampelographic variety; in addition, the juice of the grape of varieties Chardonnay, Pinot blanc, Bianca, Pervenets Magaracha due to their potassium content will be functional to improve the cardiovascular system. On the basis of the tasting we have conducted mixing of the juices from the varieties of Viorica and citron Magaracha with other juice varieties 50:50 and 70:30. Sensory evaluation showed that blending juices from the varieties of Viorika and citron juice Tsitronnyy Magaracha other varieties improves product quality and 50:50 increases by one the total score, and 70:30 - two units. Blend of the varieties of Viorica and Tsitronnyy Magaracha does not increase the total score, but gives the product a special flavor and aroma. Hence, using the grape varieties under study we can produce varietal juices with the name of their ampelographic type and blended juices to extend the assortment
