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

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

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

As a result of the studies, it has been found that higher productivity
and better meat qualities of free-range chickens were obtained in the group of poultry,
where each head of poultry had 3 m2 of walking area.


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

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%),

A medical case of diagnosis and treatment of hepatoid glands adenocarcinoma in a dog, the use of wound healing techniques of humane medicine

The paper presents a diagnostic approach to a patient with a suspected

malignant disease. Morphological description of the cytogram, cell morphology and

tumor differentiation have been given. Surgical treatment (excision of the tumor) has

been performed applying the wound healing techniques of humane medicine used in

the removal of perianal fistulas.

Influence of bulls on the reproduction indicators of daughters taking into account their productivity

The main objective of the development of dairy cattle breeding is to increase

the breeding productive characteristics, taking into account the preservation of the

reproductive qualities of animals. The research was conducted on the basis of data

from the breeding plant for black-and-white cattle breeding OOO “Zazerkalie” in the

Vologda region. Bulls-improvers were determined by the complex of selected traits,

taking into account the linear affiliation: Meson 3097402441; Retirement 11720463 of

The influence of cows’ breeds on the quality indicators of milk

In modern conditions of breeding dairy breeds of cattle, an important

element of the study is the influence of breed and quality indicators of milk. The studies

were carried out in 2019 on the basis of the SHPK “Plemzavod Maysky” Vologda region

on the quality indicators of milk from Ayrshire and black-and-white cows in the amount

of 15663 milk samples. Based on the results of milk samples, a research database on

milk quality indicators was formed and a comparative characteristic was carried out

Productivity of varieties of jerusalem artichoke with different density of standing

The work presents the results of a three-year field three-factor experiment. The productivity of Jerusalem artichoke (Skorospelka and Interest varieties) has been researched on the soddy podzolic soil with different plant stand: 47,6; 31,7; 20,4 thousand plants/ha; with two variants of mineral nutrition (calculated dose by the balance method and for full compensation of nutrient removal). It has been found that the best productivity has the Interest variety in raw (69,8 t/ha) and absolutely dry (15,4 t/ha) biomass.
