The production of eggs is one of the most important indicators of the productivity of poultry, including chickens The main purpose of breeding chickens in the collections of genetic resources - conservation of genetic diversity. The chickens from the collection of genetic resources it is also possible to receive products, for example, in the form of eggs. The account of the egg productivity of the chickens showed that the intensity of egg production varies among representatives of different directions of productivity. The most stable egg-laying was possessed by chickens of breeds New Hampshire, Black Australian, Dutch white. These breeds are bred as breeds of egg direction of productivity. But they are characterized by long downturns in egg production, lasting more than 7 days. Chickens of meat direction by stable, but low intensity of egg production. All the chickens had a short period For all chickens a short period is characteristic, when the egg-laying is kept at a certain level. It is 30-40 days, after which there is a gradual decrease in this indicator. Such a high level of genetic diversity in egg production in gene pool makes it possible to use this bird as a model object for studying its features
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
In the article, there were shown the experimental researches describing the influence of parameters of electrical ozonization of the premises of egg storehouse at concentration of ozone in 20 mg/m3 on survival of following stimulants: S. aureus, S. choleraesuis, P. vulgaris, E. coli. There was determined that ozone has an ability to detain the growth of fungi on biological substrates as well as it slows down the process of mould appearance on egg shell surface even at 90% of relative moisture. The aim of scientific experiment is obtaining of regression models of influence of parameters of electrical ozonization on main sanitary-model microorganisms contaminating the shell of incubation eggs. To assess the effectiveness of ozonization there was adopted the parameter of survival for four main pathogenic microbiological test-objects which predominate on egg shells. The correlation and regression analysis of factors and determination of value of equation coefficients there were conducted using the program STATISTICA 6.1. The correlation analysis was made by the method of Pierson. Approximation was obtained by the method of polynomial. On the results of researches there was determined that the least survival of present test-bacteria at concentration of ozone in 20 mg/m3 is achieved at exposition 84 minutes. So, the rational time the electrical technological process of ozonization of egg storehouse of poultry factories presents the sum of obtained exposition and time of regulation
In this work, the authors presented the results of monitoring urolithiasis in cats in Krasnodar in the period from 2016-2017. The authors established the sexual, age and breed predisposition of animals to this pathology; the seasonality of the disease was studied. An analysis of the actual data and reports of various authors made it possible to conclude that urolithiasis in cats is a polyethological disease. As a result of carried out hematological studies, the presence of an inflammatory process, which was manifested by lymphocytopenia, an insignificant increase in neutrophils and monocytes, as well as hematocrit, was ascertained. A laboratory analysis of urine showed that urine, as a rule, is turbid with an admixture of blood and sand, precipitating rapidly. The authors found an increase in the volume of urine in sick animals due to the inability to remove it, the specific gravity fluctuated within the limits of 1.015-1.020; pH = 7.5-8. With microscopy of the urine sediment, both unorganized and organized sediments were detected. The ultrasound examination of the bladder showed the presence in its cavity echo-positive particles in a suspended state, as well as sections of the desquamated mucosa
A comprehensive assessment was made of the own productivity of repair pigs and the quality of sperm production of boars of different breeds. Imported boars and mumps had thin bacon 13-15 mm, high early ripeness 145-153 days and a depth of "muscular eye" 53-53.9 mm, indicating an increase in the content of lean meat in the carcass. However, the length of the trunk of the animals was 120 cm, which corresponds to the first class of the instructions for bonitation. There was a significant difference in the growth rate of repair young (about 300 g), which indicates the individual characteristics of animals and the possibility of selecting the best animals for reproduction of the herd. Assessment of pigs by phenotype is an important element of breeding work on complexes. It is established that the quality of sperm production is affected both by the breed and the season of the year: the volume of ejaculate and the concentration of spermatozoa in all breeds are greatest in the autumn-winter period. Boars Maxgro were distinguished by an increased volume of ejaculate, but a low concentration of sperm compared to a large white breed and landrace. During the year, the greatest fluctuations in sperm concentration in large white breed boars were observed ± 133 million / ml, the smallest - Landrace ± 29 million / ml, which contributes to the uniform production of semen doses for insemination
