USE OF NONTRADITIONAL FERTILIZERS IN CULTIVATION OF PLANTED SCOTCH PINES ON THE RECULTIVATED GROUNDS
The results of use of nontraditional organic fertilizers on the basis of wastewater sludges and sawdust in sand pits earth stabilization are considered. It was ascertained that a dose of introduced fertilizers has higher influence on hydrophysical and agrochemical properties of soils than shelf life of the fertilizers. A tendency of enhancing growth of intended purpose planted pines on the back of improvement of physical and chemical and biological properties of sandy soils, enrichment of species composition with grassland vegetation after nontraditional organic fertilizers treatment is revealed
The article is dedicated to the problem of sorghum use in the rations for agricultural animals and poultry. Grain sorghum, the nutritious properties of which are same or exceed those of maize, can be the major crop in the structure of combined fodder for poultry
There was shown the perspective of variety-crab use as pollinators of apple-tree plantations. There were shown the economic characteristics of varieties-crabs (terms and length of pollen fertility etc.) There was made the selection of pollinators (crabs) and main industrial varieties for creation of monovarietal apple-tree plantations
In the article we have developed and studied feed additives in broiler diets based on natural montmorillonite varieties. Biological effect of Ekobentokorm additives due to their mineral composition and adsorption properties because of the big nano-pores and vitamin-mineral adsorption feed additive (WMACD), additionally, the effect has been included in its composition of biologically active substances. Effect of use of Ekobentokorm sorbent additives in feed for broilers and vitamin-mineral adsorption feed additives (WMACD) contributed to the increase of meat productivity, preservation of poultry, eating and feed conversion, the improving the carcasses
Modern commodity sturgeon breeding is one of the
profitable and dynamically developing directions of
fish farming in the Russian Federation. Only the
system of Rosrybhoz has more than 40 enterprises of
different ownership forms for the cultivation of
sturgeons. In 2012, in agricultural farming of the
Russian Federation we had grown more than 2.0
thousand tons of sturgeon. Crucial role to maintain
normal functioning of the body of the fish when
grown in closed recirculation systems plays complete
and balanced nutrition. Proper organization of
biologically full feeding of fish helps to maximize
expression of their genetic potential. The article
presents the results of the researches of the efficiency
of using feed concentrate from vegetable raw
materials called "Sarepta" in the composition of feed
additives for 2-year old Russian sturgeons
The analysis of the selenium deficiency of sows has been reviewed. The medication for treatment and prophylaxis of selenium deficiency of sows has been presented. Its preventive effect has also been given in the article
The article proves a positive effect of feeding with saffron cake and premix based this substance on growth and development, nutrient utilization ration, morphological and biochemical parameters of blood of calves of black-motley breed
The article presents the results of two researches and production experiments conducted on broiler chickens grown in the area with high technological background in feed heavy metals and at the risk of aflatoxicosis. Experimental data obtained during the first experiment suggests that in order to optimize biology and agro-food value of meat with excess of heavy metals and the risk of aflatoxicosis it is advisable to grow broiler chickens of the domestic cross-country of "Smena -7" In the barley-wheat-sunflower-type animal feed of broiler chickens of this cross one should include the formulation of a mold inhibitor of methoxy - phenyl.
During the second research and production experience for broiler chickens of “Smena-7” cross it has been found that with the joint supplements in animal feed to the high background of heavy metals and aflatoxin B1 preparations of beet pectin and methoxy - phenyl having absorption properties, there is an increase of slaughter and meat qualities. At the same time, the meat of poultry has increased its protein-quality score and decreased the concentration of heavy metals in the meat , which helps to improve consumer properties of poultry products
This article describes quantitative evaluation of add-ing succinic acid in the bran substrate when cultivating Pseudomonas fluorescens
A fundamental element of the technology is the use
of beef cattle in the economic purposes of biological
resources of animals. In the development of modern
technologies there is a lack of focusing on one of the
main features of cattle – its own perception of the
environment, that is panoramic (binocular) vision. In
the modern cattle breeding we focuse on the
development of a variety of exterior signs. However,
one of the indicators that affect the behavioral
responses of animals (the degree of development of
the muzzle and the forehead of the animal, the shape
of the head) does not have due importance. The
author has conducted its degree of development
studies in bulls and cows of different breeds. Along
the length of the head, meat breeds (Hereford,
Aberdeen Angus, Simmental, Charolais) gave way to
Red Steppe 14.9; 15.5; 5.5 and 5.0 cm (27,5; 28,6;
10,1 and 9,2%, P
