In the article we present the results of the researches of the influence of low temperatures on the quality of citrus pectin. Comparing the information before and after freezing shows that qualitative indicators are decreasing, but only slightly
The article substantiates a necessity to apply the
method of interspecific hybridization in durum
winter wheat breeding, using the present soft winter
varieties for improvement of frost and drought
tolerance at the beginning of germination; resistance
to snow mold, fusariosis and bacteriosis of
ears and grain. The article presents the results of a
comparative study of different types of crossbreeding
at interspecific and intraspecific hybridization
due to germination, emergence, productivity. It has
been shown that intraspecific hybrids ‘T. durum
оз. х T. durum оз.’, interspecific hybrids ‘T. durum
оз. х Т. аestivum оз’ and ‘Т. аestivum оз. х
T. durum оз.’ possessed the highest germination
and emergence with 71,8/75,3% for direct and
60,4/82,5% for backward, 42,8 and 35,5% and
55,4 and 64,1% respectively. In backward (triplecross)
cross-breeding of F1 interspecific hybrids
with durum winter wheat the grain germination
was down to 37,4 and 36,6%, but the emergence
was up to 64,1 and 69,7% and reached the level of
intraspecific hybrids. According to the elements of
ear (head) productivity (grain mass per head, number
of seeds per head), interspecific double-cross
hybrids of the first and the second generation significantly
conceded to intraspecific hybrids, but
they matched them in a number of spikelets and
grain size. The triple-cross hybrids exceed the
double interspecific hybrids in this respect, but
they concede to double-cross and triple-cross intraspecific
hybrids. We studied the principle of splitting of interspecific hybrids of the second
generation ‘T. durum оз. х Т. аestivum оз.’ and
‘T. durum оз. х T. durum оз.’ (direct and backward)
and the triple-cross hybrids obtained from
cross-breeding of interspecific and intraspecific
double-cross hybrids F1 with durum winter wheat
The article presents materials on comparative study of the nutritional value of chickpeas and peas which are widespread in the arid zone of the Southern Urals. The scheme of the scientific and economic experiments involved the assessment of yield formation of chickpeas and peas during the vegetation. The study showed that different varieties of chickpea and pea have considerable difference in the content of nutrients. The amount of crude protein in the pea grain ranged from 25.1 to 26.8%, and chickpea – 21.7 - 22.9%. With regard to the fat, its highest concentration was in chickpea grain - 3.63%, on average, which is 1.16% higher than on average in the pea grain. The chemical composition of the pea and chickpea grain of different varieties points to differences in their composition and homogeneity within the culture. Basing on the study, we recommend to sow chickpea and pea grain in the middle of May to obtain the highest yield, this, in turn, has a positive effect on the nutritional value of the crops. When selecting plants for cultivation in the conditions of the Southern Urals, it is preferable to choose the variety of Madonna pea, which has a higher potential for yield than the chickpea variety Krasnokutsky-123. It has been experimentally found that chickpea grain has better moisture-retaining power in a bound condition during the vegetation period as compared to the relevant characteristics of pea grain, which is a positive drought-resistant value of crop. In structural elements of the harvest the peas showed the trend of the highest rates in comparison with the corresponding elements in chickpeas
The purpose of the research is to compare the effect
of a new symbiotic feed supplement created based
on propionic and lactic acid bacteria with a widely
used domestic and foreign enzyme-probiotic
preparations in chickens 0-28 days of age of the
Lohmann Brown egg cross. In the experiment, there
were six groups of chickens: group 1 received basal
diet (BD); group 2 – BD + symbiotic preparation;
group 3 – BD + Bacell; group 4 – BD + Agrocell;
group 5 – BD + Agroksil; group 6 – BD + Ollzaym
Vegpro. Average daily gain, food conversion rate
per 1g of weight gain, digestibility of organic matter,
crude protein, crude fiber, crude fat, made up
respectively: group 1 – 8.17, 1.91, 71.4, 58.3, 68.0,
81.1; group 2 ˗ 8.36, 1.90, 72.4, 60.2, 69.7, 88.1;
group 3 – 8.13, 1.91, 73.1, 60.2, 69.7, 88.1; group 4
– 8.33, 1.86, 74.2, 62.5, 72.2, 87.6; group 5 – 8.50,
1.83, 77.3, 64.1, 73.4, 95.4; group 6 – 7.91, 1.92,
73.2, 67.5, 70.7, 94.3. The growth rate of chickens
fed with symbiotic feed supplement was 2.3%
higher than in the control and they showed the
highest fiber digestibility. The chickens on diet with
Agroksil enzyme efficiently raised growth rate
(+4%) and reduced feed costs (-4.2%). Agrocell
increased weight gain by 2% and reduce feed costs
by 2.6%. The growth rate of chickens fed Ollazaym
Vegpro was the lowest (96.8% of control), despite
the fact that it increased significantly the
digestibility of crude protein, but slightly improved
the digestibility of other nutrients. Outcome:
symbiotic feed supplement may be of interest as a
means of increasing the productivity of chickens

The article provides evidence of the high social value of dogs as the most common among pets. We present the results of determining the main causes of illness in dogs and the role of nutrition in the formation of this indicator: the share of diseases of the digestive system and various metabolic diseases accounted for more than 70 % of the total of substantiated cases to the clinic. We have estimated chemical composition of feed premium, industrial production, assessed according to the standards of the National research Council (NRC) for dogs of small breeds in the period of pregnancy and nursing puppies. We have established the feed requirements of pregnant and lactating bitches (Yorkshire Terrier) for key nutrients and bioactive substances. Recipe is made up and we manufactured food standards NRC from natural ingredients; conducted a scientific experiment to assess the impact of both feed on milk productivity indices of mothers and indicators of growing puppies (body weight at birth, weight gain). We have convincingly demonstrated the advantage of using natural food as from a physiological and economic perspective, as it is accompanied by a marked reduction in the cost of the dog and of the cost of the puppies
The article presents the data on testing of varieties of the Austrian selection in the conditions of the central zone of the Krasnodar region. Phenological observations, winter hardiness and productivity analyzed. The influences of the seeding rate on productivity of the varieties have been discussed
Currently, personal subsidiary farms (PSF) have an
important place in solving of the food security problem
in some regions and the country as a whole. The
organization of optimal and sustainable management
strategy of maintenance for PSF should be planned
according to the study of functioning of PSF. The
authors propose a unified methodical approach for
complex accounting of energy costs of external and
internal flows involved in the production of
agricultural products. Comparative energy
characteristic of the functioning of the two personal
subsidiary farms located in the Tomsk oblast and
having different socio-economic and climatic
conditions is presented in the article. Both farms are
located in the taiga zone of Western Siberia.
Calculations of the energy content of all the incoming
and outgoing flows involved in the economic activities
of PSF showed that the flow of technogenicanthropogenic
energy is the most energy-intensive for
both farms. Some conformity in the energy structure
of consumption of their own product takes place
despite the different types of stockbreeding
specialization. An assessment of the level of selfsufficiency
in food has shown that more favourable
socio-economic conditions create preconditions for an
increase of the anthropogenic flow. While PSF located
in remote areas are forced to conduct of business
activities with maximum using of natural resource
potential
The article presents the results of further research of a streaming scheme of interaction between agricultural (AGC) and processing (PP) agricultural enterprises. Mathematical models were developed and the results were shown for a quantitative comparative evaluation of the efficiencies of the combined company (AGC + PP) and processing (PP) agricultural companies
The fattening of Holstein cattle for more than 90 % provides the beef cattle division of the firm «Agrocomplex» based in the village of Vyselki, the Krasnodar region. The share of the Aberdeen Angus breed is 6.3 % and Charolais at 0.6 %. The reason for insufficient supply with fattening complex of Charolais cattle is a high indicator of severe parturition, postpartum complications, and reduced productive longevity of cows of breeding herds of these breeds. In a "Livestock complex" bulls of breeds of Holstein, Charolais and Aberdeen Angus reach the required values of live weight for the established standards of the breeding time. Charolais have the best indicators of absolute and relative weight gain and the shortest feeding season. The profitability of cattle fattening in CJSC company "Agrocomplex" is low, but the efficiency of the industry is ensured by the presence of its own processing plants. To improve the profitability of beef production it is required to increase the proportion of specialized breeds for meat productivity; to generate the most uniform by age and live weight of the group; identify the cause of the high rate of culling of Charolais cows for postpartum complications and take action to address them
