The production potential of agricultural enterprises: structure, volume and utilization efficiency
The present situation in the supply of agrarian sector with materials, labor and financial resources is characterized by special degree of intensity and instability. The majority of agricultural producers have not enough own means for financing extended reproduction. In this regard it is necessary to consider the question of rational and effective usage of available production potential. The article provides the methodological approaches to defining the structure and methods of assessing the elements of the production potential and offers its the synthetic parameter. The article specifies the degree and the efficiency of the available resources.

Efficiency of producing conserved fodder on the basis of fodder-grain crops
The article provides the results of the scientific research on the influence of harvesting terms on the productivity of fodder-grain crops (barley and its mixtures with pulse crops) and productive effect of the conserved fodder on animals. Total productivity of one hectare, which reaches over 100 metric centners of feed units due to the combination of fodders-grain and post-cut crops, is illustrated.

Monitoring, strategy and tactics of controlling resistance of the agent of potato late blight to phenilamids
The article studies the status of the resistance of Phylophtora infestans (Mont.) de Bary population to metalaxil in the conditions of the Republic of Belarus. It is proved that the level of fungus resistance is directly proportional to the intensity of systemic phenilamide group fungicides used against it. The analysis of the data obtained has not revealed any interrelation between the character of late blight seen in potato and its agent resistance. It is determined that resistance indication is mainly timed to a type of A1 compatibility. The article offers the measures on restoring Ph. Infestans population sensitivity to metalaxil.

Optimizing the combination of animal breeding and plant growing as the factor of increasing the efficiency of agricultural production
The article provides the main principals of rational combination of animal breeding and plant growing. It illustrates that soil conditions and the character of soil use must determine the structure of animal breeding, its specialization, volume of stock and produce. It provides the calculations of the optimal density of pig and cattle stocks per hectare of land as well as the volume of stock per average and larger farms, depending on the productivity of lands, the degree of their cultivation, the share of grains and their yields.

The calculation of the sagging of constrictions on biogenic grounds keeping in mind their stage character
The article suggests calculating compression curves of organic parameters of the biogenic grounds and neglecting the compressibility of the mineral parameters, because the latter is incomparably smaller. Keeping in mind the proposals the empiric formula received has much less deviations. Because of the fact that the sagging of the construction on biogenic grounds has very considerable volume, the preciseness of the calculations ensure economically better solutions

The interrelation between the exchange of iron and metabolic processes in the pregnant cows
The article examines the issues of iron slate exchange in pregnant cows in different periods of pregnancy. Indices of protein, mineral and lipoid exchanges of the 3rd, 6th, and 9th month of pregnancy as well as the interrelation of transport and erythrocytes stock of iron are determined. The correlation between plasma indices of iron exchange and electrolyte composition of serum is studied.

The ways of reducing the penetration of radio nuclides into the chain soil-fodder-animals in the contaminated areas of Mogilev region
The article provides the scientific basis of animal breeding on the contaminated agricultural lands and the system of measures to ensure animal breeding according to the Levels RSL-96 of the Republic of Belarus. It analyses the organization of the feed base and rations balanced in primary nutzitives, which might be recommended to the farms of Mogilev region suffered from Chernomyl disaster.

Mahtmatical model - the prognosis of the epizootic process of VLKRS infection in spontaneous conditions
The prognosis of the epizootic process of cattle leucosis was based on the biological balance of the stock volume in the populations of the specific specie (via natural or artificial reproduction) as well as on the parameters of incidences and intensively of affected animals, established in various Belarusian farms. The main criteria of the prognosis are the initial level of incidences, initial and final stages of infection of the population within a year and the percent of the stock reproduction. The mathematical models considered characterize the epizootic process of cattle leucosis as a dynamically developing system with ups and downs, deviations in the parameters of incidences, intensity of infection, number of healthy and ill animals, number of incoming and disappearing animals.

Economically useful and biologic peculiarities of pigs in crossings and hybridization.
The article studies the influence of two- and three- way crossing and hybridization on the commercial and biological properties of pigs (LW, BM, BBN and D breeds). LW pigs were used as controls. It was found that owing to geterosis fattening ability and carcass quality of hybrid and cross bred progeny had been improved by 5,7- 9%. Crossbred sows (LWxBM) mated to boars gave progeny of higher quality than control ones, which allowed to have an extra profit at about $291,05 per sow per year (16,4% higher than in control group). Pigs of this genotype have more valuable meat by its physical, chemical and consumable properties.

Using whey in the diets of calves
The efficiency of using the concentrated acidofill whey (containing 20% of dry matter) and hydrolyzed whey enriched with lactates HWEL-1-40 (containing 40% of dry matter) is studied in the article. The study was conducted using the black-and-white calves. In addition to the main diet the animals of the 1st group were given HWEL-1-40 (2,5 g/kg of body weight) and the animals of the 2nd group were given concentrated (20%) acidofill whey. As the result of this the feeding ability grew by 3,8% and 4,5% respectively (in comparison with the control group). Using grain additives resulted in the growth of the daily gain by 9,8% and 6,2% respectively. The feed consumption per 100 kg of gain was lowered to 4,2% and 1,4% respectively. During the study the digestion was normal.

Biochemical and biophysical prerequisites for introducing the technologies of deepened processing of raw materials in fodder production
The quality improvement of mixed fodder production under modern conditions should be based on the development and introduction of the new technologies of deepened grain forage processing, which allows significantly increasing the efficiency of usage of all natural grain potential. The article provides the analysis of the biochemical content changes of the cereal and legume grains under the influence of different factors (temperature, pressure etc). Anti nutritional qualities of grain limiting its wide use in animal feeding have been described in the article. It also suggests the methods of inactivating the above mentioned anti nutritional substances.

The combined harvest of flax: prospects and ways of development
The most considerable losses of the flax crop occur during realization of harvest work. It is possible to lower them to a minimum by using the harvesters (50%) and separate harvest (50%) technologies. In this way separate harvest deseeding is made under two circuits: both in field and on fax mill. The preparation of flax at the combined harvest is carried out on rolled technology and only in extreme weather conditions it can be carried out in sheaves with machine formation of portions for cones. In the Republic of Belarus the base complex of machines for such harvest has been created. Mechanized harvest groups at the flax mills are the important organizational principle of the development of the combined rolled flax harvesting.

The prerequisites for the development of the mathematical model of heat supply to the spring-summer green house
In Belarus is spring and autumns the daylight hours are quite long. When using solar energy for plastic greenhouse heating we must take into consideration variation of incoming solar energy during the day, dependence upon state of atmosphere. In this case it is expedient to include a subsoil heat accumulator in the heating system for it to store the heat energy. The derived analytical expression allows also choosing a material for manufacturing subsoil heat accumulators to be installed in greenhouses.
