Description

The invention relates to the field of agriculture. An additive to feed is proposed to control the activity of the cicatricial microflora of a ruminant animal, including (gram component / kilogram of the composition, calculated on the dry matter): oligofructose - 100-400, inulin and / or gum Arabic - 150-350, sorbitol - 100-300, easily digestible carbohydrates - 50-150, phospholipids - 50-200, essential oils - 2-5, chitosan - 5-10. The technical result is the normalization of metabolic disorders associated with defects of the microflora of the rumen of cows, in particular with depression of microorganisms from the group of lactate utilizers.

The technical field to which the invention relates.

The invention relates to agriculture, and more specifically to additives in feed for ruminants and their use.

The level of technology

The problem of removing the negative energy balance in cows after calving is still relevant.

The analysis of the state of the microflora of bovine scar caused by the authors showed that under the conditions of starchy excess in the diet there is a significant depression of growth and activity in the leading groups of microflora and, first of all, it belongs to the group of lactic acid bacteria and fungi. Under these conditions, the activity of lactate utilizers decreases, as a result of which lactic acid accumulates and acidosis occurs, which in turn prevents the synthesis of glucose in the blood and its use for energy in cells and tissues.

It has been established that using previously known methods of normalizing cicatricial digestion using a composition of liquid polysaccharides can significantly improve the situation with the health of cows, productivity, etc. (see patents of the Russian Federation No. 2444906, 2472352 by the same authors).

However, as it turned out, 30% of the livestock of cows has extremely serious metabolic disorders associated with the defect of the rumen microflora, including depression of the lactate utilizer group, which is still associated with the occurrence of acidosis. The authors found that the decrease in the activity of cicatricial microflora is largely due to the depressant effect of mycotoxins, which contaminate grain and silage, which are the main components of a cow's diet. Thus, in this situation it is necessary to introduce an effective toxin neutralizer into the diet.

In addition, in the experiments, the authors showed that the situation improves if the composition increases the concentration of oligofructose - the most important growth factor for lactic acid bacteria.

Summary of Invention

The authors found that deep acidosis in cows can be eliminated by administering polysaccharides to dry cows 2 weeks before calving and after calving for 100 days in increased doses: 50-100 g of the composition (calculated on dry matter) / head per day before calving and 200-250 g of the composition (in terms of dry substance) / head per day after calving.

The found composition and method of administration of the product create conditions for the management of cicatricial digestion and dramatically reduce the risk of acidosis. Accordingly, milk productivity increases, and most importantly improves the health of cows and reduced culling.

The proposed new composition of liquid polysaccharides has the following composition: 1 g of the component / 1 kg of the composition (calculated on the dry matter): oligofructose - 100-400, inulin and / or gum arabic 150-350, sorbitol - 100-300, easily digestible carbohydrates - 50-150 , phospholipids - 50-200, essential oils 2-5, chitosan - 5-10.

The implementation of the invention

The composition of the new product has been tested in a number of farms. Below are examples of the method.

Example 1

Feed additive was tested in the farm "Zhdanovsky" Nizhny Novgorod region. Cows in the diet were given 8 kg of feed (feed, fodder), 20 kg of silage, hay. In addition, liquid polysaccharides with the composition according to patent No. 2472352 were injected into the diet of the control group (50 heads).

In the composition of the usual diet in the experimental group (50 goals) used composition according to the invention of the following composition g / kg (dry matter)

Oligofructose 200 Inulin 200 Sorbitol 250 Easily digestible carbohydrates (glucose, fructose, maltose) 100 Phospholipids (lecithin) 150 Oil of carnations 2 Chitosan ten

The method of administration - in the control cows after calving 100 g / day per day, in the experimental group polysaccharides according to the proposed method were administered in the dry period at 150 g / goal per day (dry basis), after calving 200 g / day per day (dry substance ). The duration of the experiment is 3 months. The test results are shown in Table. 2

From the data table. 2 shows that the proposed method with a new composition of components in the product and the method of product introduction provides a higher level of energy in the body (blood glucose), which corresponds to a higher milk yield and reduced level of culling.

Example 2

Feed additive was also tested in the farm "Urozhaynoe" of the Leningrad region.

The control group of cows (100 heads) received a normal ration: 8-40 kg of feed, including fodder, in addition silage - 15 kg, hay - 2 kg and liquid polysaccharides according to the RF patent for invention No. 2472352.

The composition of the usual diet in the experimental group (100 heads) additionally introduced liquid polysaccharides of the following composition 1 g / 1 kg (on dry matter):

Oligofructose 250 Inulin 250 Sorbitol 250 Easily digestible carbohydrates 150 Phospholipids 100 Cinnamon oil 2 Chitosan 15

Feed additive was also tested in the farm "Homeland" Kazakhstan.

The control group of cows (200 heads) received a normal ration - 10-12 kg of feed, including fodder, besides silage - 20 kg, hay - 3 kg and liquid polysaccharides - in accordance with the RF patent №2472352.

The composition of the usual diet in the experimental group (200 heads) additionally introduced the additive according to the invention according to the scheme: two weeks before calving - 220 g of the composition (calculated on dry matter) / head per day, after calving - 200 g of the composition ( dry matter) / head per day for 3 months. The additive according to the invention had the following composition (1 g of the component / 1 kg of the composition, calculated on the dry matter):

Oligofructose 287, Inulin 200, Ummirabic 200, Easily digestible carbohydrates (glucose, fructose, maltose) 100, Phospholipids 150, Sorbitol 50, Chitosan Yu, Anise oil 3 ml.

The research results are summarized in table. four.

From the presented results, it can be seen that the proposed composition and the method of administering polysaccharides, including the dosage during periods of dry and pudding, can significantly improve the parameters of animal health and their productivity. Thus, based on the analysis of the results obtained in various farms of the Customs Union, it can be concluded that the most optimal

maximum effects obtained using the following composition, namely 1 g of the composition (in terms of dry substance) / head per day: oligofructose - 100-400, inulin and / or gum arabic - 150,350, sorbitol - 100-300, easily digestible carbohydrates (glucose , fructose, maltose) - 50-150, phospholipids (lecithin) - 50-200, essential oils, totally or separately - 2-5, chitosan - 5-10.

At the same time, the dosage of the composition according to the invention is carried out in the following mode: 2 weeks before calving, 220 g of the composition (in terms of dry substance) / head per day, for 3 months after calving, 200 g of the composition (in terms of dry substance) / head per day.

The composition and method according to the invention allow to normalize the microflora of the scar and eliminate or alleviate deep acidosis in cows after calving.
