Hematological Blood Values of Store Pigs According to the Automated Analysis Data
Pig breeding, as an independent livestock sector in Russia, has been developing steadily since 2008. This was facilitated by the adoption of the agricultural development program, which assumed an increase in state support for the agro-industrial complex. However, the intensification of pork production places high demands on the quality of livestock, which necessitates the use of breeds, types and lines that can withstand the loads of modern industrial technology without reducing productivity. The article presents the morphological parameters of the peripheral blood of store pigs of large white breed, obtained using a hematology analyzer. Based on the analysis of the data obtained, the authors have came to the conclusion that there is a tendency to an increase in the number of erythrocytes and hemoglobin, and a decrease in the number of leukocytes and platelets with age in the blood of fattening pigs. These changes can be associated with high growing capacity of fattening piglets and the implementation of effective preventive measures on the farm in relation to piglet anemia.
Influence of humic substances on yield, quality and keeping qualities of red beet
The research carried out in the Pskov region on sod-podzolic mediumloamy soil during 2017-2019 has shown, that Lignogumat potasssic and Gidrogumin humic preparations increase the field germination of such three varieties of the table beet as Bona, Krasnaya Koroleva and Mulatka by 10-17% in pre-sowing seed preparation. After seed and plant treatment with the humic preparations in stage of the second pair of true leaves, the beet varieties have entered the industrial ripeness stage earlier: the Mulatka variety - for 5-8 days earlier, the Bona variety - for 3-5 days earlier, and the Krasnaya Koroleva variety - for 2-3 days earlier compared to the control plants. The beet plants treated with Gidrogumin have exceeded the control variant (water) by leaf weight by 18.8-28.5% and by root weight by 2.9-12.0%. After being treated with Gidrogumin, the Mulatka variety stands out among the other varieties by the average root weight of 325 g (+12.1%), its yielding capacity of 51.6 t/ha (+22.8%), high yield of commercial beet roots (88.4%) and the lowest total losses (4.5%) during short-term storage. After treating the seeds and plants with Lignogumat potasssic and Gidrogumin humic preparations, the quality of table beet products has not been worsened and the nitrate content has not exceeded the maximum permissible concentration. The cultivation of the Mulatka table beet variety combined with Gidrogumin treatment is profitable from the economic point of view. This variant has given the highest yield of 51.6 t/ha with the lowest labor intensity – 2.70 man hour / t and the cost of 4360 rubles/t, the maximum conditional net income – 8640 rubles/t and the highest level of profitability of 198.2%.

Comparative productivity evaluation of meadow clover (trifolium pratense l.) different varieties in the Vologda region
It was found that the highest hay yield compared to the standard Trio
variety was observed in the Taezhnik variety (105.3 C/ha) in the conditions of the
Vologda region on sod-podzolic medium loamy soil for 2017-2019. The variety to
control provided a significant increase in yield of 15.9 C / ha (18%). The Allure variety
showed a significantly lower yield compared to the standard (17 C / ha, i.e.19%). The
rest of the studied Ranniy-2 and Roseta varieties provided the yield at the standard
level. The tested varieties of meadow clover showed good and almost excellent winter
hardiness which is 4-4.7 points. The content of “raw” protein exceeded the control
grade of Ranniy-2 (by 1.2%), Taezhnik (by 0.9%), Allure (by 0.5%). For the collection
of “raw” protein with a yield of green mass, the Allure and Roseta varieties were inferior
to the standard by 153 and 11 kg / ha. Ranniy- 2 and Taezhnik varieties provided the
collection of “raw” protein with a green mass yield of 1155 and 1245 kg/ha, respectively,
exceeding the standard by 173 and 263 kg / ha. The average and large correlation of
such indicators as the yield of clover varieties and plant height from r = 0.551 to r =
0.743 was revealed. A weak relationship was established between such indicators as
leafiness and yield (r = 0.434 – 0.525), yield and protein content (r = 0.451), protein
content in the green mass and plant leafiness (r = 0.448).
Сultlvation of narrow-leaved fireweed (сhamaenerion angustifolium) together with maral root (rhaponticum carthamoides) (willd) jlin
The authors investigated the ability of narrow-leaved fireweed
(Сhamaenerion angustifolium or Ivan-chai) to grow together with maral root
(Rhaponticum Carthamoides) (Willd.) Iljin. in the Northern part of the non-chernozem
soil zone of Russia. Both plants were found to start grow immediately after melting
of snow cover. The phenological flowering period of the maral root occurs earlier than
that of the narrow-leaved fireweed. The experiment has revealed that in a mixture of
grasses, narrow-leaved firewood is being suppressed. In the third year of life there is
a thinning of the stalk of Ivan chai due to a drop in the shoot-producing capacity of its
roots. During the period of the experiment the productivity of the grass mixture was
lower, than in control version by 5 t/ha. In the control version, the metabolic energy
and raw protein collection were 11.2 GJ/ha and 179.3 kg/ha higher than in the grass
mixture. The maral root in the third year of growth develops a strong root system and
a leaf rosette, which results the unfavorable conditions for the narrow-leaved fireweed
(Сhamaenerion angustifolium) and it becomes obvious that it is displaced by the maral
root from the cenosis composition.
Quality and nutritive value of Galega orientalis silage depending on the moisture content of the silage mass
In the experiments we studied the effect of the moisture content in
plant raw materials when making silage from Galega orientalis on its nutritional value
and quality. It has been found that the moisture content of raw materials has a great
impact on the quality and nutritional value of silage. The lower the moisture content
in the plant raw materials when making silage, the more nutritious and better silage is
obtained, which must be taken into account when preparing it.
Rational area of walking zones in raising broiler chickens

Forming yielding capacity of green and dry mass of topinambur depending on its harvesting time
The article presents the research results on the influence of topinambur
harvesting time on the green mass and absolute dry matter yields. The one-factor
experiment has been launched according to the method of B.A. Dospekhov in the
educational and scientific experimental field of Perm State Agrarian and Technological
University. The experiment has followed the following scheme: 1 – gathering of green
mass on the 10th day after the flowering phase, 2 – gathering of green mass on the 20th
day after the flowering phase, 3 – gathering of green mass before tuber lifting. According
to the research results, the harvesting time of green mass has not had any influence
on its yielding capacity (13.1‒15.5 t/ha), or the dry mass yield (3.01‒3.44 t/ha). There
is a tendency for the green mass yield to decrease from an earlier harvest period to a
later one – by 1.7‒2.4 t/ha and dry mass-by 0.16‒0.43 t/ha. The plant survival rate
(88-92%) and the plant standing density (3.2‒3.4 pcs/m2) before harvesting have not
shown any dependence on the harvesting time. A significant increase in absolute dry
matter content of the crop continues until the flowering phase and reaches its maximum
of 6.45 t/ha. Due to the outflow of nutrients from the aboveground part of the plant to
the ground one, there is a sharp decrease in dry mass yield by the first harvest time (by
3.28 t/ha) after the flowering phase. The maximum height of plants is also found in the
flowering phase –153 cm, after which the plant stops to grow. The highest vitamin C
content in topinambur green mass has been found when mowing it before tuber lifting
(65.6 mg/kg), the highest carotene content has been observed when harvesting the
green mass on the 10th-20th day after the flowering phase (17.2‒18.0 mg/kg), the
highest crude ash content has been found when harvesting on the 20th day after the
flowering phase (3.4%).
Nutrition and quality indicators of succulent feeds of the vologda region in accordance with the requirements og GOST
The article covers the main requirements for the bulky food quality
when feeding dairy cattle. Silage, wilted grass silage and haylage are succulent feeds
that form the basis of dairy farming diet and can reach up to 80% of it. A comparative
study of succulent feed has showed that silage and haylage harvested from wilted
perennial legumes contain more whole protein (by 29.14% and 37.25%, respectively),
feed units (by 12.00% and 19.23%) and less dry matter (by 24.93% and 4.36%),
crude fiber (by 1.66%). The deviation of haylage nutritional value in comparison with
GOST requirements is insignificant in terms of dry matter content by 12.47%, whole
protein by 1.11%, crude fiber by 2.69% and sugar by 4.48%.
Consequently, the lack of feed and errors of their use, that lead to a decrease in
milk productivity and loss of product quality, can be compensated for by the bulky feed
quality and full-value in the used diet. Thus, tests of harvested feed aimed at adjusting
the rations in the system of normalized feeding of animals, which allow realizing the
inherent productive capabilities of dairy cows, are of great importance.
