Submitted by red on Sun, 12/06/2022 - 15:30

Silage-making is a simple and reliable way to preserve the green fodder mass in a succulent state. The article regards the options for silage-making of fodder galega with the addition of French willow (rosebay willow-herb) in various ratios. The quality indicators of the finished feed have been determined. It has been revealed that the pH of all silage variants does not reach the biological limit values for the development of lactic acid bacteria (3.0 - 4.2).

The Influence of Agricultural Methods on Formation of Agrophytocenoses of Perennial Grasses of Intensive Use in the European North of Russia

Submitted by red on Sun, 12/06/2022 - 15:27

The article presents the results of a four-year research on the study of agricultural methods for creating agrophytocenoses of perennial grasses for intensive use. According to the results of the studies, it has been found out that the content of seeded grass species in the grass stand has been high regardless of the species composition and method of sowing and has been 83-94.1% in the third year of use. The method of sowing has had an impact on the botanical composition of agrophytocenoses – the amount of weed vegetation has been higher with the subcover method by 1.2-1.4 times.

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%),

The article presents a working model for monitoring the basic body processes in animals. The main approaches to the implementation of the proposed model are described and disclosed. It has been indicated that the requirements for assessing feed quality and actual nutritional value include the task core to be solved not only in order to control viability, but also to increase the dairy farming efficiency at agricultural enterprises of the Vologda region.

The article outlines the regulatory requirements for assessing the quality of green fodder and the actual nutritional value of green mass at farms of the Vologda region. More than 100 green mass samples were investigated for the period 2016 - 2018.

Yields of legume - cereal grass in pasture use depending on the species composition UNDER the Vologda region conditions

Submitted by red on Wed, 27/12/2017 - 13:11

The article presents the results of the four years research (2012-2015) on yield capacity, nutritional value and botanical composition of grassland phytocenoses. The most productive is recognized as a four legume-cereal grass mixture on the basis of Carmine red clover and eastern goat’s-rue Krivich in combination with the fescue and timothy grass. Mixture is characterized by a high proportion of legumes (40.9%), enhanced yielding from 1 ha fodder units (2851), digestible protein (400.6 kg / ha) and high nitrogen-fixing ability (69.7 kg / ha).
