EFFECT OF BENTONITE ON MEAT PRODUCTIVITY AND QUALITY OF PORK GILTS

abstract 1181604044 issue 118 pp. 773 – 782 29.04.2016 ru 735
In our country, great influence is given to the production and consumption of agricultural animals' meat with high consumer qualities. In this regard, the livestock producers, particularly pigs, are to increase production and improve product quality. Works on using some natural mineral complexes - bentonite and zeolites as a source of macro - and trace elements are performed. The aim of the research is to study the effects of bentonite feeding with free access on the meat productivity and hygienic meat quality of young pigs for fattening. Best effect on the slaughter indexes of fattening gilts had bentonite feeding with free access that resulted in significant superiority of the animals in the experimental group over the control counterparts on pre-slaughter live weight, slaughter weight, chilled carcass weight, slaughter yield, carcass length, the "muscle" eye area and the backgammon weight. More favorable effect in the longest muscle on the dry matter and protein synthesis was provided by bentonite feeding with free access. Due to this, the gilts of the experimental group were in significant advance of their control counterparts in concentration of dry matter and protein in meat. Along with this, the longest muscle of young pigs on fattening in the experimental group had the highest protein value, as according to the protein-qualitative indicator the animals of this group were in significant advance of the control counterparts. Feeding bentonite clay with free access had a strong detoxifying effect that is against control counterparts of gilts in the experimental group showed the significant reduce of lead, zinc and cadmium concentrations in the meat

PRODUCTIVITY, DIGESTIVE METABOLISM IN YOUNG PIGS WHEN USING BENTONITE FEEDING

abstract 1181604045 issue 118 pp. 783 – 793 29.04.2016 ru 730
For further increasing pork production and to increase its quality it is necessary to provide complete and balanced feeding of young pigs for fattening. The special place takes the issue of satisfying their physiological needs in macro and micronutrients. The most cost-effective step in these circumstances is using bentonite clays as natural mineral supplements. The aim of this work was to study the effect of the addition of bentonite of Zamankulskaya field on the energy growth, digestibility and the digestibility of nutrients of the diet of young pigs. According to the results of the survey, the best productive effect was when ensuring free access to the bentonite, so that the young pigs of the 3rd experimental group vs control group had significant superiority according to gross and average daily live weight gain and feed products. According to the results of scientific and economic experience, it was found that with free access to the bentonite best economic and useful indicators were observed in the animals of the 3rd experimental group against the control analogs, as they had significant superiority in terms of absolute live weight gain and feed consumption per unit of production. During the physiological exchange of experience the most beneficial effect on the hydrolysis of complex organic compounds had bentonite feeding with free access of pigs. The result was a significant superiority of the experimental animals over the control ones in coefficients of digestibility of dry matter, organic matter, crude protein, crude fat and NFE. To improve the digestibility and absorption of nutrients in the diet of young pigs it is advisable to feed them with bentonite clay as natural mineral supplements with free access

MOBILE POLLINATION AS A PARADIGM FOR INDUSTRIAL BEEKEEPING

abstract 1181604060 issue 118 pp. 990 – 1000 29.04.2016 ru 758
The article analyzes the state of the domestic beekeeping. It is proposed, as a paradigm of the industrial beekeeping, to use honey and pollination systems. Over the past 25 years, because the hard economic reforms in the public sector, there was almost double reduction of honey collection. Russian beekeeping is in the hard situation because of the low yields and the use of outdated technologies. Russia's share in the global honey market does not exceed 1 %. A more viable was apiaries of private households. Beekeepers receive a basic income from the sale of honey. Meanwhile, in developed countries more than 60% of the income of integrated use of honeybees account for pollination activities. In modern conditions of the Russian vector of development of beekeeping should be its production and technological re-equipment, improving its bioecological principles and socio - economic transformation of the infrastructure sector. Using mobile honey- pollination systems, which provide bees with feed conveyor due to the frequent movement of the apiary, honey plant and beekeepers can reduce the cost of manual labor for loading and unloading hives. In the Kuban Agrarian University we designed the pavilion design (RF patent number 2,284,103 ), awarded with a silver medal of Concours Lepine (France, Paris ). Using a mobile pavilion allows to conduct all production functions: honey and pollination production and reproduction, ensuring the competitiveness of the industry

ANALYSIS OF THE IMPACT OF PREPLANT TREATING OF SEEDS WITH INDUSTRIAL ALTERNATING ELECTROMAGNETIC FREQUENCY (EMF PF 50 HZ) ON THE GERMINATION ENERGY OF MIDRIPENING SPRING BARLEY SEEDS OF THE VARIETIES OF VAKULA, VIKONT, RATNIK

abstract 1181604071 issue 118 pp. 1129 – 1138 29.04.2016 ru 586
The use of physical factors for preplant stimulation of seeds increases vigor, germination and improves the yield of agricultural products. One of the effective ways to improve seed grain quality is to impact on the seeds using physical factors, in particular, an alternating electromagnetic field of industrial frequency of 50 Hz (EMF of IF of 50 Hz). We studied the impact of EMF of IF of 50 Hz on the energy germination of mid-ripening spring barley seeds of promising varieties Vakula, Vikont, Ratnik. Carrying out the experimental studies we used a laboratory setup with annular pole points of rectangular cross section. Our disperse analysis resulted in data on germinative energy of seeds of spring barley varieties Vakula, Vikont, Ratnik, which showed that while treating seeds of spring barley by an alternating electromagnetic field of industrial frequency of 50Hz, we obtained the best values of germinative energy of seeds of Variety Vikont with a mode of processing being equal to W = 16%, T = 2 c, L = 0,03 m

abstract 1181604080 issue 118 pp. 1256 – 1266 29.04.2016 ru 399
One of the prospect directions in new sunflower hybrid development is cold resistance breeding in the emergency stage. Sunflower hybrids with uniform emergency and high rate growth under the low temperature conditions could allow to introduce sunflower in the new regions of our country and so to increase sunflower acreage. The aim of our work was to screen all sunflower available samples for growth rate under the low temperature and to select the best lines and initial material for future breeding. 140 sunflower lines of VNIIMK breeding and hybrid populations on their base were used as a material. Seeds of every sample were incubated during the 10 days in the thermostat under 100 С. Seed germination was evaluated for the each sample along with the seedling size. As a result the most prospective samples were selected for the future breeding work. On the second stage of the experiment one selected population was evaluated on the Breeding station of Vavilov’s AllRussian Research Institute of Plant Industry in the city of Pushkin (Leningrad region). Seeds from the best plants were obtained in this place and will be used for the new lines development. So the effectiveness of selection of sunflower samples for growth rate under the low temperature was verified and this method could be used to introduce sunflower in the new regions of our country with more severe climatic conditions

abstract 1181604082 issue 118 pp. 1282 – 1292 29.04.2016 ru 831
Development of confectionery sunflower openpollinated varieties (OP-varieties) is a prospect direction in sunflower breeding. High price level for confectionery sunflower seeds pushes forward the breeding program. Contrary, it is necessary to offer product, meeting consumer’s expectation for large seeds, good dehulling rate, proper oil and husk content. The aim of our work is to study morphometric peculiarities of seed structure for sunflower OP-varieties of different types – oil and confectionery, and to identify the best samples for using in the breeding program as an initial material. The study was done at All-Russia Oil Crops Research Institute (VNIIMK) named by V.S. Pustovoit (Krasnodar) in 2014 and 2015. Seeds of 6 OP sunflower varieties of VNIIMK breeding were used as a material (confectionery type – Dzhinn, SPK, Lakomka, Oreshek, Borodinskiy and oil-type – Muster). OP-varieties were sown by randomized blocks with 3 replications. Every plot had 4 rows. It was shown that seeds of confectionery sunflower OP-varieties had higher values of main traits (length, width and thickness) in comparison with oil-type sunflower. Seed traits analyses allowed identifying the best confectionery samples (Dzhinn and Oreshek) for future breeding

THE EFFECT OF "GORLINKA" MUSTARD PROTEIN-CONTAINING FEED CONCENTRATE ON NUTRIENT DIGESTIBILITY OF AGRICULTURAL POULTRY

abstract 1181604084 issue 118 pp. 1304 – 1318 29.04.2016 ru 452
This article presents the results of the impact of "Gorlinka" mustard protein-containing feed concentrate in the feeding of broiler chicken of the cross of "Cobb-500" on their performance and nutrient digestibility of the feed. The studies were conducted in the conditions of Krasnodonskaya Poultry farm in the Ilovlinskiy district of the Volgograd region. Full or partial replacement of sunflower meal with "Gorlinka" mustard proteincontaining feed concentrate in the feed mixture for the experimental broiler chickens contributes to the increase of the coefficients of digestibility of nutrients compared to the birds in the control group. The use of "Gorlinka" mustard protein-containing feed concentrate in the composition of feed for broiler chickens has contributed to higher coefficients of digestibility of nutrients: dry matter – 0.51-1,37%, organic matter – 0.6-1,99 %, crude protein by 0.8- 2,24 %, crude fiber – 0,34-1,65 %; crude fat – 0.94- 2,29%, compared to the birds in the control group. Nitrogen balance was positive in all groups; the use of nitrogen from the accepted experimental broiler chickens was higher in the experimental groups than in the control by 2.89-of 7.93 %. The use of nitrogen from digested nitrogen was higher in the experimental groups in comparison with the analogues from the control group by 2.65-of 7.97 %. The use of calcium and phosphorus by poultry was also higher in the experimental groups

THE EFFECTIVENESS OF THE USE OF "GORLINKA" MUSTARD PROTEINCONTAINING FEED CONCENTRATE IN FEEDING OF BROILER CHICKENS

abstract 1181604085 issue 118 pp. 1319 – 1332 29.04.2016 ru 691
This article presents the results of using "Gorlinka" mustard protein-containing feed concentrate, instead of sunflower meal in the feeding of broiler chickens of the cross of "Cobb-500". The studies were conducted in the conditions of Krasnodonskaya Poultry farm of the Ilovlinskiy district of the Volgograd region. Replacing sunflower meal with a product of processing of oilseeds which is "Gorlinka" mustard protein-containing concentrate, in the feed mixture in the experimental broilers had a positive impact on the productivity, physiological state of the birds, product quality and economic performance. The use of this mustard protein-containing feed concentrate in feeding of meat birds contributes to the increase of live weight by 3.46-of 6.65% and slaughter yield by 1.38-1.98% and improvement of quality indicators of the carcasses. Morphological and biochemical parameters in experimental broiler chickens in all the groups were within the physiological norm, which indicates a normally occurring redox processes in the poultry organism. However, adding "Gorlinka" mustard proteincontaining feed concentrate into experimental feed for broiler chickens contributed to the increase in the content of total protein, calcium, phosphorus in blood serum in comparison with analogues from the control group that received sunflower cake. As a result of the research, the economic effect in the experimental groups was up 710,40-1085,53 rubles
