Abstract

FIELD: fodder production for feeding farm animals. SUBSTANCE: feeding additive contains brewers' draff, meat-and bone and/or bone flour and blood of slaughtered animals or products of its processing taken in ratio (1-1.5): (4-5): (1.25-1.5) on dry substance, respectively. Preferably, used as animal protein is blood of slaughtered animals or products of its processing, for example, blood flour. Feeding additive has a high degree of digestibility due to its balance to amino acid composition. Introduction of feeding additive in ration of piglets increases their daily average of liveweight gain by 7% in comparison with the control. EFFECT: higher efficiency. 2 cl, 1 expn

Description

 The invention relates to the feed industry, namely, to obtain feed from waste from food production, such as brewing and meat.

 Known feed additive for feeding farm animals, including waste brewing in the form of protein sludge from beer pellets.

 This supplement does not provide with all the necessary set of nutrients, sufficient and necessary for a balanced feed.

 The proposed feed additive is balanced in amino acid composition, has a high degree of digestibility, which allows it to be used in any feed, as well as as an independent feed.

 The feed additive consists of brewing waste in the form of beer grains, waste from the meat processing industry - meat and bone and / or bone meal and blood of slaughtered animals or its processed products (blood meal, etc.) taken in the ratio (1-1.5) : (4-5) :( 1.25-1.5) on a dry matter basis, respectively.

 In this combination, the components of the feed additive, differing in the content of protein, macro- and microelements, vitamins, not only complement each other, but also contribute to increasing its biological value as a whole due to its high digestibility and bioavailability.

 The proposed additive allows to achieve optimal protein synthesis in animals and to most effectively use the essential amino acids present in it, which is ensured only if all of the above components are taken in the above ratios.

 So, the mass fraction of protein of meat and bone and bone meal is 30–40%, digestibility 28–30%, and beer grains 6–8% and 45–48%, respectively. However, meat and bone and bone meal do not contain the necessary set of vitamins, which are rich in beer grains. A significant content of vitamins actively affects the digestibility of flour proteins due to the formation of water-soluble protein-vitamin conjugates with high bioavailability.

 A special role in the proposed feed supplement is played by the blood of animals, whose proteins are equivalent to meat proteins in digestibility and are almost completely absorbed by the body. Blood contains mineral salts, carbohydrates, lipids, vitamins, enzymes, hormones and other biologically active substances necessary for the normal functioning of the body as a whole. Blood is used as blood meal or as a coagulant. In addition, you can use boiled blood, canned calcium oxide.

 Thus, the introduction of this additive in any food allows you to achieve the economy of the latter primarily due to its better digestibility.

 The processes occurring at the biochemical level in the body of farm animals, namely the synthesis of protein, collagen, regulation of the central nervous system and homeostasis, maintaining the color of muscle fibers, depend to a large extent on those substances that the proposed feed supplement contains for this purpose.

 The proposed ratio of the components is most optimal and changing it in one direction or another or excluding one of these components can lead to disruption of both protein and carbohydrate-vitamin balance, which will lead to unbalanced feed.

 The feed additive is obtained by simple mechanical mixing of the components taken in the proposed proportion.

 The feed additive can be introduced into any feed, regardless of the object of feeding and the composition of the feed itself. The exception is feeds with a high protein content, since oversaturation of feed rations with protein can lead to a decrease in digestibility per feed unit, to an additional feed consumption and, accordingly, an increase in the cost of feeding animals.

 Example. A feed additive is prepared immediately before feeding farm animals or previously, for which they take beer pellets, meat and bone meal and blood meal in a ratio of 1: 4: 1.25 on a dry matter basis, respectively. The components are mixed in a mixer, dried, and then packaged.

 In the experiment, 30 piglets of large white breed of 3 months of average live weight of 26.5 kg were used.

 Animals were divided into two equal groups by random selection.

 The first group was injected into a standard diet with 20% feed additive, consisting of beer grains, meat and bone meal and blood of slaughtered animals taken in a ratio of 1: 4: 1.25, respectively. The second group was supplemented with a standard diet by adding 20% protein sludge from beer grains.

 The experiment was carried out for 30 days, at the end of which the output of the slaughter food products was recorded.

 As a result of feeding in piglets of the first group, the carcass yield was 69–77%, the carcass length was 94–99 cm, the meat yield 60–61.5%, the fat yield 30–34%, and the bone yield 11–12.3%. In piglets of the second group, these indicators were lower by an average of 5%.

 During the experiment, it was found that the introduction of the proposed feed additives into the diets of piglets increases the average daily gain in young animals by 7% compared with feeding the diet with the addition of protein sludge from beer grains.
