One of the priority tasks set for the Belarusian agro-industrial complex is to increase production efficiency by reducing the cost of agricultural products. It is recommended to use local raw materials and resources as much as possible in order to reduce the import of expensive protein and vitamin-mineral complexes and thereby increase the profitability of the industry. One urgent and affordable solution is the introduction of sapropel additives into cattle rations.

Numerous studies have proved: organic sapropel deposit "Udhodva" of Pruzhany district, extracted by ALC "Agrosemproduct", positively affect not only the metabolic processes, health of cattle, but also its productivity and live weight gain.

The high efficiency of sapropel additives was confirmed by the head of the laboratory of feeding and physiology of cattle nutrition of the Scientific and Research Center for Animal Husbandry of the National Academy of Sciences of Belarus, Doctor of Agricultural Sciences, Professor Vasily Radchikov:
- The topic is very promising for Belarusian agro-industrial complex, because the inclusion of sapropel in cattle rations will reduce the cost of buying imported feed additives and thus save a certain amount of money, which is very important for agricultural organizations. The fact that organic sapropel is an available source of minerals. It contains more than 70 components of minerals, protein and humic acids, which intensify digestion in the rumen. Besides, sapropel can replace up to six percent of grain in the cattle ration. In addition, if we are talking about milking cattle, there is an increase in the productivity of the herd.

In confirmation of the above, it is worth citing the results of experiments conducted by the Republican Unitary Enterprise "Scientific and Research Center of the National Academy of Sciences of the Republic of Belarus on cattle breeding" at the State Enterprise "ZhodinoAgroPlemElita" of Smolevichi district. The study group included cows in the middle of lactation with the productivity of six tons of milk, as well as young cattle.

Actually, the result did not make us wait long. Already in three months the average daily milk yield increased, fat content and protein content in milk increased, the content of somatic cells decreased sharply - by 4 times - in comparison with the control group (Table 1).

TABLE 1: Productivity of milking cattle
Note: I group - control, received a standard diet; II group received mixed fodder with sapropel replacing 4 percent of grain; III group received mixed fodder with sapropel replacing 6 percent of grain.
The results achieved allow milk to be sold at the price of "Extra" milk quality, which significantly increases the revenue of milk suppliers. The standard ration included mixed fodder "60 B" for dairy cows, silage and hay mixture, hay and green mass. In the experimental groups, a sapropel additive was introduced instead of grain.

In addition to the increase in productivity, the economic effect also draws attention. It was established by experiment that the cost per kilogram of milk in the control group I was 0.47 rubles, while in groups II and III the cost per kilogram decreased by 6.4 and 4.3 percent, respectively. The additional profit for the products obtained during the experiment in these two groups per cow reached 144.2 and 126.5 rubles. Taking into account that sapropel also replaces up to six percent of grain in the ration, we can talk about an increase in economic efficiency of milk production.

As for the experimental stock of young cattle, depending on the age, the feed "KR-2" or "KR-3" with the inclusion of sapropel, silage mixture, hay and milk were present in the diet. Results of the researches showed (Table 2, 3) that feeding calves mixed fodders "KR-2" with sapropel in amount of 4 and 6 percent increased the live weight gain by 3,4 and 3,9 percent and decreased the prime cost of growth by 1,8 and 0,3 percent compared to the control group respectively.

Note: I group - control, received a standard diet; II group received mixed fodder with sapropel replacing 4 percent of grain; III group received mixed fodder with sapropel replacing 6 percent of grain.
TABLE 3. Changes in live weight and average daily growth rate of young animals when adding sapropel to KR-3 mixed fodder
TABLE 3. Changes in live weight and average daily growth rate of young animals when adding sapropel to KR-3 mixed fodder
Note: I group - control, received a standard diet; II group received mixed fodder with sapropel replacing 4 percent of grain; III group received mixed fodder with sapropel replacing 6 percent of grain.
As a result, during the experiment additional profit per head amounted to 5,44 rubles in group II and 0,91 rubles in group III. If we talk about experimental groups which received sapropel together with mixed fodder "KR-3", additional profit per head was 3,66 rubles (group II) and 1,86 rubles (group III).

What's the secret?

The fact is that due to its rich composition and optimal ratio of organo-mineral substances, the natural sapropel additive has an antibiotic effect. It enhances the digestibility of nutrients, as it improves the fermentation process in the rumen, and simultaneously stimulates the immune system of animals. As a result of regular use, the number of pathologies of childbirth decreases and hepatoprotective effect increases. The effectiveness of sapropel feed additives in treating cattle from chronic botulism has been proved. The risks of mastitis are reduced by 96 percent. In addition, sapropel stimulates the formation of propionic acid from which glucose is synthesized in ruminants up to 60 percent of the demand, and in the rumen content it reduces the concentration of branched-chain volatile fatty acids - isobutyric and isovaleric. These are involved in the synthesis of amino acids, and at the same time there is a drop in the concentration of ammonia.

Simply speaking, the secret lies in the unique composition of sapropel, which can work wonders when used properly.
