This article discusses the results of a study to determine the impact of different primary tillage to sunflower yield. The task of the research was to determine the impact of primary tillage in the agrophysical and agrochemical soil properties. It has been established that the content of productive moisture during the growing period in 0-100 cm soil layer does not depend on the method of processing. Surface treatment of the soil did not have negative effects on soil properties and its agrophysical structure in comparison with moldboard ploughing. . When dump processing improves the density of the soil, accumulates more moisture in the autumn winter period, reduces the weediness of sunflower perennial weeds. Productivity in contaminated areas increases by 3.3 - 5.4 c / ha. On weed-free crops, the yield increased by 2.5 - 3.5 c / ha, due to the improvement of the physical parameters of the soil
The article presents data on the prevalence of
colibacillosis of pigs in farms of the Krasnodar region
in the period 2010-2016. Colibacillosis is widespread
in pig farms of the Krasnodar region. In different
years, it was recorded at 32.6 - 55.6% of bacterial
infectious diseases of pigs. And only in 2013-2014, in
farms of the region colibacillosis was not registered.
Among the bacterial pathology, colibacillosis in pigs
in the farms of the Krasnodar region is in the first
place after staphyloccocus (3 - 15 %), streptoccocus
(2-13,7 %), and diseases caused by conditionally
pathogenic microflora (17,9-20 %). In the Krasnodar
region, we annually allocate different serotypes of E.
Coli that vary depending on areas and farms, however,
regularly in pigs in the Krasnodar region there are the
following serotypes: A8, О20, О119, О26, О86 in
Bryukhovetskiy, Dinskoy, Kalininskiy, Korenovskiy,
Kurganinskiy, Kushchevskaiy, Labinskiy regions of
the Krasnodar territory. According to the reports of
outbreaks, colibacillosis in pigs for several years were
recorded in the Central, Korenovskiy, Kushchevskaya,
Labinskiy, Primorsko-Akhtarskiy, Seversky,
Slavyanskiy, Tbilisskiy, Timashevskiy, Ust-Labinskiy
districts of the Krasnodar region and in the city of
Krasnodar. After 2013-2014, after the total absence of
the disease in the region, there were reported outbreaks
in 2015 in some farms in the Timashevskiy district,
and in 2016 – in Kurganinskiy
The main diseases of lactating cows occur in the first
two months of lactation, i.e. during the production
peak of productivity. They are caused by the changes
in metabolism during the transition period, which are
not supported by adequate changes in the organization
of feeding, or rather sufficient to ensure cows with
nutrients, which causes a number of closely related
diseases. To allocate any of them is not possible, as
their manifestation depends on a number of reasons,
and depending on situation may prevail one or the
other. Among the most common diseases, there are
ketosis, milk fever (paresis of maternity), dysplasia of
the abomasum, acidosis, mastitis, endometritis,
laminitis and leukemia. These diseases cause the
greatest problems in herds with high productivity, and
are caused by changes in metabolism in cows in the
transition period and the inability to properly feed the
animals at this time. To identify the causes of these
diseases we do not need to study each of them
individually - it is enough to deal with the peculiarities
of metabolism. This period includes the month before
calving and the first or second month of lactation, but
the most important are 3 weeks before calving and 3
weeks later. In order to prevent metabolic disorders
there were developed and tested feed for feeding cows
before calving and immediately after calving. Their
effect was studied on milk production and health status
The article presents results of a comparative study of
the experimental groups of Holstein animals
belonging to the Reflection Sovering line: four groups
of repair calves and four groups of bull-calves. The
peculiarities of their growth and development were
studied at higher daily rates of drinking milk and early
training of experimental animals to plant feeds with a
probiotic supplement of cellobacterins in the milk
period. The technology of growing the animals of the
experimental groups had differences: I-control group -
up to 6 months of age was grown according to the
traditional technology for farming: 200 kg of milk (for
50 days) and 400 kg of return (from 50 to 110 days),
concentrated feeds consisted of starter feed (50%)
and (50%) maize, the same amount of concentrated
feed and the same composition was obtained by
calves from experimental groups; II-test group - up to
6 months of age received an increased amount of milk
(for 25 days) - 200 kg and 400 kg of return (from 25
to 60 days); animals of the III-rd experimental group
- up to 6-month-old age received an increased rate of
milk drinking (for 50 days) - 450 kg and return (from
50 to 110 days): heifers - 600, bulls -800kg. Animals
of the IV-experimental group-up to 6 months of agereceived
an increased rate of milking (for 60 days) -
450 kg and return (from 60 to 120 days): heifers -
600, bulls -800 kg. The calves of all experimental
groups were fed a probiotic preparation of
cellobacterin in an amount of 3 g for each animal up to 18 months of age. The live weight changed
significantly depending on the age and the level of
feeding of the experimental animals. The use in the
feeding of calves of experimental groups of increased
daily average milk yields and the addition of a
probiotic to cellobacterin in the diet positively
influenced the growth and development of
experimental young animals, promoted a more
intensive increase in live weight
This article is devoted to the study of the species structure of helminths of the American mink, raccoon and wolf, conducted from 2006 to 2017. The study was subjected to 69 corpses of American mink - 30 of reed-bed, 22 flat, 17 of the Piedmont; 42 dead raccoon to 21 of the foothill and mountain; 24 corpse of the wolf - 8 from overflow land, foothill and mountain landscape-geographical zones of the Northwest Caucasus. The analysis of the results of the study showed that the determining factor in the formation of helminthocenoses of American mink, raccoon and wolf is the species structure of trophic-epizootic chains, the links of which are these predators, as well as species that act as intermediate, additional and reservoir hosts. Feature of helminthiases in carnivorous mammals is determined by a group of fodder. A dynamic increase in the number of species in the structure of helminthocenoses of American mink, raccoon and wolf was established, which is due to the anthropogenic transformation of natural ecosystems, violation of historical biotic relationships, including in the "parasite-host" system. The analyzed species of wild carnivores are involved in the support and formation of natural foci of such hazardous parasites as metros, Alaris, pseudamphistomum, mesocestoides, echinococcosis, trichinosis, dirofilariosis
Currently, in the Krasnodar region the indicators of
cow productivity are steadily increasing. This was
facilitated by two factors: the improvement of animal
genetics and the introduction of innovations in
technology. Novoplastunovskoe is one of the first
farms, which paid much attention to a significant
change in the technology of dairy cattle. Work began
with the construction of barns "light type" with walls
in the form of opening curtains for the American
project. The premises are equipped with "boxes" for
individual rest of animals with bedding in the form of
sand; automatic heated water logs; on the roof there is
a transparent skate, providing an increase in lighting
and additional ventilation; ceiling fans and additional
water sprinklers are installed to regulate the
microclimate. The milking parlor is equipped with
high-tech equipment and is integrated with the Israeli
computer program “AfiFarm”. Research was carried
out on an estimation of zoohygienic conditions in the
winter and summer periods; the technology of
processing and clearing sand - bedding for animals is
studied; the interior and exterior characteristics of the
cows of the Ayrshire and Holstein breeds adapted to
the new conditions have been determined; with the
help of the computer program “AfiFarm”, the
dynamics of single and daily milk yields, the content
of fat and protein in milk; calculated economic
indicators of milk production from different breeds of
animals
The article gives mechanisms of the influence of the
main sex hormones on the sexual cycle of cows and
heifers and the effectiveness of their insemination. The
effectiveness of gonadotropin preparations releasing
hormone, prostaglandin and progesterone, used to
induce sexual hunting, was studied. The use of
combined use of hormones and prostaglandins is
effective for synchronizing sexual hunting, regardless
of the stage of the sexual cycle on which healthy
animals can be at the time of their administration. The
reasons for the retention of the yellow body in the
ovary are very diverse. The results of the studies
indicate that a particularly close relationship exists
between the yellow body and the uterus
The article presents a production system analysis of high-quality winter wheat grain and the problem solution methods based on mechanization production processes strategy through a new generation of equipment and innovative improvement of machine technologies were outlined. Deterioration of grain quality indicators in the country was marked: the proportion of strong wheat is not more than 0.5% of commodity grain resources, and about 80% of exportable parties is wheat of 4...5 classes. Thus, it is possible due to the process mechanization to raise the grain quality. A well-known method of functional-cost analysis was applied to ground machine technological operations, which are the first to be developed in order to improve the wheat quality in the entire technological system, the demand for which is reduced abroad. The basic technological principles of production of high-quality grain were designed. They have three subsystems: the structure of the wheat varieties for the agricultural producer, the previous crops for wheat, features of cultivation technology of valuable varieties on the basis of intelligent manufacturing systems machines. The mechanization of high quality grain production processes was proposed. It can provide engine technology improvement due to rational composition machine-tractor units of new generation. They allow to abandon the outdated usual items of machinery used in their system and dramatically raise labor productivity due to the combination of operations, quality of work, yield and reduce costs. The features of mechanization on harvesting and post-harvest grain refinement are reflected with the aim of improving its quality. Applied to various forms of management, intellectual grain sorting means of mechanization recommended, which contribute to an increase in wheat quality. The impact of "neveika" technology with the completion of the heap at the stationary place on the grain quality improvement was marked
Pressure mode compressed-air installation use that allows transfer of biological poultry wastes was based on the investigation of agricultural cargo hauling equipment. The installation includes a compressor with a receiver, a conduit, a cork forming section, a valve and a reservoir. As a result of using the installation the energy intensity and consumption of the process are reduced during the transportation of the material, labor costs are reduced and the issue of environmental protection is resolved. To optimize the working process of the compressed-air installation, the volume of the blow-off boiler, the length and diameter of the pipeline were determined. It was established that the most important technological parameter of the installation, which is productivity, depends on its design parameters and physical and mechanical properties of the initial material. The determining influence on the performance is the air pressure and the speed of product movement. The required air pressure is regulated by the compressor, and the speed of transportation is due to the design parameters of the installation and the physical and mechanical properties of the material. These aspects are taken into account in this project for process optimization of the poultry biological waste transportation
The issue of resource saving in the process of preparation of feed mixtures of multifunctional mobile units on livestock operations shows the need for further qualitative research in the preparation of feed for feeding with the goal of full realization of the genetic potential of animals. Modern cars often do not meet the above requirements that require new solutions. The theoretical study of grinding process feed stem proposed biplane segments allow you to define conditions and to identify the main factors affecting the studied process, and subsequently reduce their impact on the operation of the machine as a whole
