The Quality of Silage Made from a Mixture of Fodder Galega and French Willow

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).

Evaluating harvested feed in the Vologda Region for the presence of nitrate compounds

The improvement of agriculture is inextricably linked with the increase in feed production. The intensive feed production system involves using high doses of nitrogen fertilizers. This significantly increases the yield, but at the same time nitrates accumulate in soil, water and feed. Excessive amount of nitrates causes the wrong course of functioning in natural ecosystems and animal organisms, there is a decrease in the biological value of products. Meanwhile, the importance of nitrates and their impact on human health has increased recently.

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%),

Comparative evaluation of alfalfa silage and alfalfa silage with legumes and cereals

The article presents the results of the comparative evaluation of alfalfa silage and alfalfa silage with other legumes and cereals. The high protein content in silos is 14.45-14.73%. The fiber content is 31.07-33.04%. It contributes to easy digestion and does not require additional processing.

Sampling of feed for farm animals as an important stage of their analysis. Selection methods and tools

Sampling is an important part of feed analysis and the reliability of measurement results depends on how it is performed. It’s impossible to correct the errors occurring due to incorrect sampling in the future, and researches no matter how accurate they are, become meaningless. Modern feed sampling is a whole system of organizational and technological measures that must be performed to obtain and maintain a representative (i.e., reflecting the average value of all the characteristics of the entire batch of material) sample.

The quality of bulky feeds on the farms of the Vologda Region

The article presents the results of studying the chemical composition and quality of forage harvested on farms of the Vologda Region. As a result of detailed analysis of roughages and succulents nutritive value it has been revealed that regarding metabolizable energy and crude protein they insufficiently meet the needs of highly productive animals. The proportion of the 1st and 2nd class fodders in 2014 was as follows: 14.1% of hay, 38.5% of haylage, 44. 8% of silage.
