In the soils of rice fields, eluvial gley processes
develop, which are manifested in redistribution of silty
particles along the profile, water-soluble humus,
mobile compounds of iron and phosphorus. Most
intensively, these processes are developed in meadowbog
soils, confined to closed depressions of the plains
plain. Meadow-black soils lying on elevated relief
elements have more favorable physical, physicochemical
and oxidation-reduction properties for
cultivating rice and accompanying crops in crop
rotation. The highest yield of rice is formed on high
checks and higher at 12,4 c/ha than on low ones
The article presents the analysis of variation of daily
mean temperatures for the period 1977-2015. Clear
tendency for their increasing in pre-sowing and
especially in growing period is found. Heat supply of
separate months in pre-sowing period increased in the
row: April-February-January-December-March, and
that of growing period – in a row: May-Juny-JulySeptember-August.
Presence of slight correlation
(from -0,256 to 0,268) of temperatures in winter-spring
months with heat supply of coming spring summer
months is found. It is shown that correlation of rice
yield with temperatures of pre-sowing (DecemberApril)
and growing (May-September) periods varies
from weak to average (from 0,016 to 0,524) with a
tendency to increasing from winter months to summer
ones. Use of analog method made it possible to
estimate roughly the nature of t upcoming growing
season of rice in the current 2016: after the abnormally
warm winter one should expect the value of heat
supply of summer months to be close to normal. In the
physiological sense, such distribution of summer
temperatures is favorable for rice. Use of one of the
most effective forecast methods – smoothing the time
series (method of «moving decades») – made it
possible to evaluate medium-term rhythms of heat
supply of rice growing season and yields. It was found
that after an abnormally high level of heat supply of
the growing season, marked during last decade, we
should expect a decrease in spring and summer
temperatures - the next attack of the "cold" cycle. If
this hypothesis is confirmed, then up to 2020, and later
a natural tendency for decrease in rice yields, arising
from the adverse factors of temperature, will continue
which should also affect the economic efficiency of
the industry as a whole
In recent years, many pigs of specialized breeds,
characterized by increased meat qualities, have been
brought to Russia from Canada and a number of
European countries. The article presents the results of
the assessment of slaughter and meat qualities of pigs
of different genotypes. Danish pig meat was used as
research objects: purebred landrace (CHL), benthic
hybrid Landrasx yorkshire (LxY), three-breed hybrid
landrace hyorkshire x dyurok (LxXxD), removed from
control fattening, and developed prototypes of delicacy
products. The commission evaluation of meat and
broth showed that the boiled meat from the three breed
animals received the highest score, and the quality of
the broth significantly exceeded the samples of
purebred landrace and two-breed animals. As a result
of the tasting evaluation of the Voronezh ham, it was
established that the samples of meat from threebreeded
pigs, in comparison with the samples from
purebred meat, show the most pronounced flavor,
aroma and soft consistency
The optimal rations have been found. We have
conducted a research on the assessment of meat
productivity, biochemical blood tests. The chemical
composition of blood and meat has been found. We
have empirically chosen a content area for both chicks
and adults of black African ostriches. The article
shows a selection of optimal rations for feeding of
ostriches; we have also determined the live weight of
ostriches in groups, keeping the chicks safe in groups,
hematological studies of ostriches blood, the chemical
composition of the meat, the efficiency of premixes of

The article presents the results of the researches on the
study of the different systems of basic treatment of soil
under sunflower’s density, aggregate composition, supplies
of productive moisture on regular black soil of the
Krasnodar region
Nowadays, domestic pig production is dynamically
changing in technological and selection terms and is
one of the most effective sectors. In the current
conditions of pig breeding in intensive technology, the
requirements to the level and direction of pig
production, the rational use of genetic resources are
increasing. The development of effective methods for
the production of pork on the basis of the wide use of
highly productive breeds and types of both imported
and domestic selection allows to obtain the maximum
possible productivity of animals, to produce pork of
good quality, to reduce the cost of production and to
fully realize the genetic potential of animals. Genetic
and selection techniques have significantly changed
the physiological, morphological and productive
capabilities of modern animals. In connection with
this, the actual for the pig industry is the identification
of opportunities to increase the duration of the use of
pigs, and the inclusion of new indicators in breeding
work when creating specialized maternal lines. The
research was carried out on the electronic database
(KP ACC, OOO "Selikom", Ryazan), the breeding
center "Lozovoye" ZAO "Plemzavod-Yubileyniy" of
the Tyumen region. The center is engaged in
thoroughbred breeding and improvement of four pigs:
large white, landrace, pietren, duroc
The article presents the biennial data on infestation of
winter barley infected with his disease and pests, depending
on fertilizer rates, the main method of tillage
and plant protection. Weeds are one of the most highly
potent factors that reduce the productivity of plants.
System of agronomic plant cannot increase the productivity
of plants, if it contributes to impurity of crops.
In the studied years, the most common weeds at the
recommended tillage were dead nettle, cleavers,
chickweed, field bindweed. At zero processing - foxtail,
poppy, wild oats, Leptospermum, dead nettle, veronica.
The use of biological and chemical plant protection
products reduced the degree of expansion and
development of disease
In the leached black soils of the foothill zone of the
Kabardino-Balkarian Republic on the territory of
training experimental plant of FSBEI HE
Kabardino-Balkarian state agricultural university
named after V.M. Kokova we have studied the
effect of soil and climatic conditions of area of
cultivation and application of micro – macro
fertilizers, plant growth regulators and biological
products on the crops of lentils, their impact on the
efficiency and quality. It is proved that in general,
the natural conditions of the foothill zone are
favorable for cultivation and obtaining high yields
of major crops. The analysis of meteorological
conditions of the area (typical for the whole area)
shows that there are great reserves and
opportunities to obtain high and stable yields of
lentils grains. These morphological, genetic and
agrochemical parameters of leached chernozem
growing zones suggest the soil favorable to the
growth and development of lentils. On average,
during the years of studies, the number of plants on
which we had marked tubercles, on the example of
Rauza varieties in the background variant, was
63.7%; the use of the drug called Agropon C in
combination with sodium selenite increased by
15.2% the number of plants with root nodules.
Increasing the number of plants with root nodules
was accompanied with increasing the number and
weight of nodules per plant by 8.1 pc. and 10.1 mg.
respectively. The highest yield - 2.66 t/ha under
experimental conditions was obtained in the form
of joint use of the drug Agropon C and sodium
selenite with a seeding rate of 2.2 million viable
seeds per hectare, which is higher than the
reference version for this seeding rate by 0.46 t/ha
or 17.3%. The maximum value indicators of protein content in the seeds and collecting the
protein per unit area reached with the use of joint
application of Agropon C and sodium selenite,
where we achieved the seeding rate of 2.2 million
of germinating seeds per hectare and made up
29.6% and 787 kg/ha, respectively
The article shows the historically developed situation
and the actual state of the production practice in
chronic mycotoxicosis of a bird. The main feed
problems in poultry farming are shown through the
prism of a review of market proposals for feed
concentrates. An overview of preventive and
compensating agents on the market, as well as a brief
description of feed concentrates based on beta-carotene
for fighting mycotoxicosis. It is shown that the
vitamin-mineral fodder concentrate "Tetra +" is an
alternative to the existing feed concentrates on the
market, the effectiveness of which has been confirmed
in experiments on laboratory animals and in poultry
feeding. Based on the analysis, a conclusion was made
about the relevance of studies to identify the
effectiveness of vitamin-mineral concentrate "Tetra +"
in livestock
The aim of the research was to study the impact of
starter complete feed (CF) with different levels of
crude fat on the chemical composition of muscle tissue
and liver of young geese. During days 5-28 the poultry
was fed CF with 5.1-8.1 % crude fat, from 29- to 60-
day age – with 5.4 %. By increasing the level of crude
fat in starter CF there was a trend to an increase of the
phosphorus content in muscle samples of geese hip
and thigh - by 4.4-9.6 %, in the liver - by 27.2-53.5 %
(P≤0,05). The chest muscles of the young geese fed
high-calorie CF had 2.8-6.0 % higher fat content, than
that of counterparts in the first group. At the same
time, there was a tendency to a decrease in the
concentration of fat in the muscles of the hip and thigh
- by 1.9-5.0 % (P˃0,05). Increased level of crude fat in
CF did not have a negative impact on the accumulation
of heavy metals in the muscle and liver of geese, the
concentration of the studied elements was within the
permissible level established for food products
