High Yields

One of the modern selection tasks in vegetable growing is quality products improving, obtaining high yields of environmentally safe wide assortment vegetables. To the new varieties of vegetable crops including winter white cabbage are specified new requirements such as market competitiveness, resistance to unfavorable environmental conditions, heat resistance of the varieties and F1 hybrids. The article is shown investigation results about studies of exogenous treatment by solutions on the base of physiologically active compounds of hormonal nature on the started process of stem extension stage activation and flowering of winter white cabbage plants. For the first time in the Dagestan conditions has been studied the possibility of hormonal regulation of the premature stem extension stage and flowering prevention of winter white cabbage after the initiation of natural induction. In our studies with an early planting there are not more than 20% of blooming plants, most varieties showed a high propensity to premature stem extension stage and flowering. The possibility of the hormonal exogenous regulation of the unfavorable winter white cabbage flowering has been revealed. The most pronounced effect on the transition to stem extension stage and flowering were provided by auxin nature preparations. In particular, treatment with NAS at a dose of 5 mg / l significantly reduced the number of blossom plants, krezatsin (50 mg / l) had a similar effect, but it was less pronounced. The use of cabbage in winter crops makes it possible to obtain two or three yields per year from the same area. Creation and introduction into production of promising and high-yielding varieties and hybrids will allow increasing production and reducing its cost.

The successful conduct of disinfection measures largely depends on the availability of veterinary practice a highly efficient, environmentally safe disinfectants. In this regard, finding new highly efficient disinfectant remains relevant. Studies found that the "Polied" (OOO "Razvitie XXI Vek, Russia) can be attributed to the highly efficient and environmentally friendly means. Solutions "Polied" have a high disinfectant activity against smooth and rough surfaces in the laboratory against gram-positive, gram-negative bacteria, mycobacteria and spores of microorganisms. Studies have established that solutions should be "Polied" obezzarajivatmi E. coli (EA 1257) concentrations of 0.1% on smooth surfaces and Staphylococcus aureus concentration of 0.05% in 1 hour from the calculation of 0.25-0.3 litres/m2. Disinfection of rough test surfaces against Escherichia coli and Staphylococcus aureus occurred after treatment with 0,3% solution of 3-hour exposure, at a rate of 0.5 l/m2. It was also found that 1.0% solution "Polied" fully obezzarazhivatel test the surface of mycobacteria (PCs-5) and at double the 0.6% concentration for 24 hours. Disinfection of rough test surfaces contaminated with spores of B. cereus (PCs 96) was achieved with a 4.0% solution at twice the irrigation rate of 0.5 l/m2 at an exposure of 24 hours. Toxicity solutions of the drug "Polied" refer to "moderate" threat (hazard class 3) and low-hazard substances (4 hazard class) when applied to the skin, mucous membranes of the eyes, and inhalation exposure on the respiratory system.

Poultry Farming

In modern poultry farming the most urgent tasks are to search for and test new environmentally safe feed and economically justifi ed additives that stimulate productivity, positively aff ect the health of poultry, and consequently increase the livability of livestock and other important zootechnical traits. In order to maintain physiologically normal processes of life, metabolism and increase the level of productivity of poultry it needs mineral components and their chelated compounds. The purpose of this work was to increase the egg productivity of poultry by using the silicon-containing poly additive Nabicat in feeding young hens and laying hens. The researches have been carried out on the poultry cross Highsex Brown under the environments in CJSC “Poultry Farm “Volzhskaya” in the Sredneakhtubinsky area in the Volgograd region. In this paper, The optimal dose of the introduction of the silicon-containing poly additive Nabicat in the diets of young and laying hens of the cross Highsex Brown has been scientifi cally justifi ed and the biological value of using an organic form of silicon has been determined. The positive infl uence of the optimal dose of poly additive on growth, consumption, and digestibility, nutrient metabolism in the poultry body, as well as egg productivity and quality of the resulting egg has been revealed. Thus, the average egg productivity per 1 hen in the control group during the experiment period was 321,3 pcs., and in the 1st, 2nd and 3rd experimental groups it was 322,6 pcs., 325,8 and 325,7 pcs., which was higher than in the control group by 0,40 %, 1,40 and 1,37 %, respectively. The average egg weight in the 1st experimental group exceeded the control by 0,43 g or 0,68 %, in the 2nd experimental group by 1,16 g or 1,84 %, in the 3rd experimental group by 0,81 g or 1,28 %. The economic eff ectiveness of using the organic silicon additive in the composition of Nabicat poly additive in the feeding of laying hens has been proved. The economic eff ect due to the use of diff erent doses of the introduction of silicon-containing poly additive Nabicat in compound feed for laying hens of the 1st experimental group was 141,66 rubles, the 2nd experimental group 962,76 rubles, and the 3rd experimental group 821,89 rubles.

The Impact

This article presents the results of studying the impact of housing and feeding conditions on broiler chickens of Hubbard RedBro cross, as well as the quality of products obtained when using floor and cage content, in a farm. It established that when receiving a mixed feed of own production using feed raw materials grown on a farm without the use of pesticides, a statistically significant decrease in potentially dangerous substances for animal health is recorded. Compared with factory feed, it has reduced the content of pesticides by 14 times, and mercury and arsenic by 24 times, cadmium by five times, and lead by ten times. The results of the study of economic indicators of growing Hubbard RedBro cross broiler chickens, as well as the chemical composition and quality of carcasses, indicated that there was no significant difference between the floor and cell conditions of keeping. Still, the use of a diet based on eco-feeds contributed to a statistically significant decrease in the concentration of toxic metals in the muscles of the poultry of the experimental groups. As a result, it found that the use of the studied compound feed in the diets of broiler chickens increased the indicators of Biosafety and ensured the production of environmentally safe ("organic") poultry meat products.

Abstract In urban centres, leaves are customarily gathered and temporarily stored in large roadside piles prior to their transport to disposal sites. To simulate the release of total phosphorus to urban runoff, birch and trembling aspen leaves were leached with distilled water in laboratory flasks. There was no difference in rate of total phosphorus release between oven-dried and non-dried leaves. An empirical equation developed from these data and knowledge of the litterfall rates for southern Canada indicated that leaves yielded from 11 to 45 mg TP m−2 of forested watershed. This amount represents up to 5% of the total export of total phosphorus from urban catchments and has the potential to exacerbate eutrophication of municipal waters if leaf pickup is not promptly enforced.
