General characteristic of a productivity of laying-hens and a quality of table eggs is given in this article
The nutrient structure of fruits of the Mountain ash of
ordinary Sorbus aucuparia L., sloe of Prunus spinosa
and their extracts is investigated. Inside them, the
standard methods in biochemistry have determined the
content of extractive substances, sugars, titrable acids,
vitamins C and P, phenolic and pectinaceous
substances. Results of analyses demonstrate that the
fruits of wild plants ripening in the conditions of
Dagestan – mountain ashes and sloe - can be
effectively used as raw materials for receiving extracts
which are rich in vitamins, carbohydrates and phenolic
connections. The possibility of production of highquality
nutrient-rich extracts from these fruits with
application of various technological modes and ways
of extraction is revealed: duration of insisting of raw
materials; various concentration of ethanol in an
extractant and ratios raw materials/ extractant. Results
of researches demonstrate that at a ratio of raw
materials/extractant 1:3 and the 70% content of ethanol
in the extractant have come the greatest extraction
from vitamin fruits P (routine) and phenols which
made respectively 56,0-65,7% and 51,4-68,3%.
Increase in extraction of titrable acids and vitamin C is
noted at 50% concentration of ethanol in the
extractant. The maximum release of sugars has come
from all fruit substrata at 30% ethanol in the
extractant. Results of biochemical analyses of extracts
have shown that carrying out extraction in the way of
double insisting on condition of selection of optimum:
concentration of ethanol in the extractant, ratios of the
raw materials/ extractant and the best time of insisting, allow to provide on average a 55-60% exit of nutrients
from the studied fruit raw materials
The steady development of modern pig farming
dictates the need for new priorities, opportunities and
requirements, such as reducing harmful environmental
impacts, more efficient use of resources, and provision
of comfortable conditions for the pig housing. The
creation of an appropriate ITS BAT in the branch will
optimize the activity of agricultural pig breeding
enterprises due to the transition to performance of
requirements based on BAT technological parameters,
to solve the problem of energy efficiency, import
substitution and increase of competitiveness. Their
integration will have an effect not only on improving
the ecological state of the environment, but also on the
economy of agricultural enterprises providing a new
approach to agricultural activity
The analysis of fruit crops saplings production in the Krasnodar region is presented. The problems of the modern fruit crops saplings production in the region are allocated and possible ways of decision these problems are given
In the decision to establish solid fodder resources
in the arid parts of Southern Russia triticale should
take its rightful place. It must be introduced instead
of winter wheat, inferior to the yield, quality and
output of nutrients per unit of area. It is necessary
to maximize the potential of new varieties of
winter triticale, as the productivity of animals
largely depends on the varietal characteristics of
the culture. Triticale has attracted special attention
by its ability to exceed the parental forms on
productivity and quality, and resistance to adverse
soil and climatic conditions and the most
dangerous disease is not inferior to rye. The
generalized data of most researchers characterize
triticale as a factor in increasing the productivity of
animals and reducing the cost of feed per unit of
output, although in some cases there is a negative
trend in reduction of productivity by the
replacement of cereal grain components for winter
triticale. Due to the enrichment of compound feed
with triticale grain by enzyme preparations and
enzyme-probiotic supplements we can greatly
increase productivity, digestibility of main
nutrients, improve meat quality and reduce the cost
of feed per unit of output. We can increase the
productive effect of triticale grain by extrusion. In
physiological metabolic experiments, it is found
that by extruding of triticale grain the digestibility
of the main nutrients is increased by 1.3-1.8%.
Extruding of triticale before feeding promotes
slaughter yield and increases the levels of protein
in the muscle. The use of triticale in rations instead
of wheat reduces the cost of the diet, the cost of the
manufactured products and increases profitability.
The study of achievements of scientists from
various scientific organizations necessitates the
further breeding work with the culture of triticale
and requires the development of innovative
technological methods that can help reduce the
concentration of pentosans and beta-glucans in the
grain
During experiments on quail it was found that use of Trilaktobaktis probiotic is characterized with the activation of major types of metabolism, including protein –by increase the total protein content (5.17%) and mineral – by increase serum calcium and phosphorus (2.71 and 19.5%, respectively); by decrease of cholesterol content (10.6%). Probiotic stimulates erythro and hematopoiesis in quail: increase of the number of erythrocytes by 2.93% and hemoglobin by 2.57% was marked. Preparation enhances nonspecific resistance by increasing lysozyme and serum bactericidal activity by 47.4% and 149.6%.Besides, use of Trilaktobaktin diets increases digestibility of organic substance (5.74%), raw protein (3.95%) and raw fiber (4.83%). Probiotics use in the diet of quail improves nitrogen digestion by 5.3%, calcium and phosphorus – by 1.4%. Under the influence of probiotics content of lactic acid bacteria and bifidobacteriain chyme of quail increases by 46.2%.Use of Trilaktobaktin quail breeding increases safety and live weight gain by 6.0% and 6.9%, reduces the cost of feeds to produce 1 kg of body weight by 7.4%, and carcass yield reaches 66.4%, providing 100% output of first category carcasses. Use of Trilaktobakt feed additive has a positive effect on the quality of meat products. Thus, carcass output was 57.1% and the amount of fat decreased by 14.4% (pectoral muscles) and 12.7% (leg muscles) relative to the control. At the same time protein content in the thoracic and leg muscles increased by 7.5% and 10.7%
The biotechnology (year - round utilization of livestock and spirit wastages) was developed for the protection of farmlands and water objects. Technology of processing of organic wastages by means of earthworms (vermicomposting) gives the chance to use wastages of livestock complexes, to make a sewage disposal at minimum energy consumption. In the field experiment which was made in the training farm called "Kuban" for the detailed studying of influence of the held events there were put the platforms. The technique of probability of estimation of ameliorative condition of an irrigated field is given in the article. The nonparametric statistical assessment of degree of soil compliance to the normative conditions is defined
The article presents the author’s insight into the theoretical foundations of plant breeding for self-pollinators and cross-pollinators. From the author’s point of view, plant breeding techniques depend on a type of pollination, population propagation and isolation from other variety pollen. Adaptive properties of crops are described as ones depending on a genetic type (genetically pure lines, populations, hybrids, pure varieties and clones). The key role of seeds in preserving a plant variety, or a cultivar, is emphasized. In the article, cultivar and yield qualities of seeds are characterized. The reasons for seed deterioration and yield decrease have been looked into. Improvement of main crops such as wheat, barley, rye, rice, soybeans, maize, triticale, sunflowers, potatoes, sugar beets is characterized in detail. The author shares the traditional point of view on the seed breeding program. It includes following steps: development phase (breeder’s seed), maintenance phase (in which a quantity of seed is maintained under high standards) and the distribution phase (production of commercial seed for distribution to the public). The difference between primary and secondary seed selection is explained. The best periods for crop rotation and crop renovation are also described. The legally enforceable standards of quality and genetic purity for different crops are presented in the article. It is pointed out that it is vital to maintain high cultivar qualities after multiplication and distribution of the new variety. Only large-scale pedigree system for seed production promotes it
This article presents the studying results of new premixes of domestic production using efficiency based on processed products, in particular - oil cakes. The research was carried out in the conditions of the second-order pedigree reproductor in LLC "Svetly" in the Svetloyarsky district of the Volgograd region in the period from 2015 to 2017. During the scientific and economic experience, the authors revealed the new fodder additives positive influence on the laying hens’ egg productivity, on the eggs morphological and incubation rates and on the got young birds. The use of premixes in layer diet, which included the fodder concentrate from the plant raw material "Sarepta" and Camelina seed oil cake, contributed to the increase in the hens laying capacity, in general, the group received in 249 and 310 pieces more than in the control one. The egg average weight from the chickens of the control group was 60.89 g; from the first experimental it was 61.33 g; from the second experimental it was 61.39 g, which was higher than in the control one, respectively, by 0.44 g and 0.50 g. While the hatching eggs morphological indices analysis, it was revealed that all parameters are within the permissible limits of the physiological norm. Fertilization of eggs in the control group was at the level of 89.33%, which is lower than in the experimental groups. As a whole, the eggs' production in groups was 20.00% in the control, 17.33% in the 1st group, and 16.00% in the 2nd test group
