CS251994B1 - Protein concentrate for monogasic animals - Google Patents

Abstract

Protein concentrate is intended for the preparation of feed mixtures, which effectively replaces soybean extracted meal. It is based on a mixture of machine-made glutinous rice, wheat gluten, feed yeast, corn press and lysine in an optimal ratio. The concentrate can be used in feeding poultry or pigs. Its effect has been verified in fattening chickens.

The present invention relates to a protein concentrate for monogastric animals, equivalent to soy extracted scrap. Presently, soy bean meal, which accounts for 15 to 30% by weight, is used as the main source of protein in feed mixtures of premonogastric animals, especially for poultry. a proportion of the complete feed mixture. Só-ja is being processed in the world in ever-increasing quantities for products used directly in human nutrition. The prospective need to count on an increasingly large proportion of its use for that purpose. With the rise in human populations in the world, the need for soy increases the need for protein for nutrition. At the same time, there is a growing need for replacing soy in poultry and other mono-gastric animal feed with substitute feeds that are equivalent in production to this deficient protein source in feed mixtures.

Attempting to replace this raw material with a single protein-containing component has not been successful: not only does the total N-content that may be lower than that of maize moldings differ (13.5% - data for N-substances always in% by weight) or fibulin (19-40%, by quality), but also higher, which shows wheat gluten (74.6%) or machinery glue (53%), but the differences are also the increase and utility of essential ami- The standard content of N-substances in soybean extracts is 43.4%, and there are also similar difficulties with proteinaceous products from other non-traditional sources, such as green plants, rape, whey and others. Other problems may arise here: the technology of preparing protein concentrates from leaves is not solved, so far the products are not yet in the market, and the technology of rapeseed protein preparation is the removal of glucose-inhibiting inhibitory substances, which complicates production and is more expensive (see, for example, J. Kolář, J. Šímová et al., Rostl, vol. 30, 1983, pp. 701-709). quite high. For example, D. A. Ledward, A. J. Taylor and R. A. Lawrie (publishers) summarizes the issue. Bu-tterworths, London 1983.

While the fortification of feed mixtures with the essential amino acid L-lysine, which is most often limiting to the use of susceptible substances, is generally known since the 1970s, the solution of the substitution of soy bean by combining four components containing proteins is not known from the literature. .

The above-mentioned disadvantages are limited by the protein concentrate for monogastric animals of the invention, which consists of a mash of machine sizing, wheat filament, fibulin, maize moldings, and L-lysine, which is characterized in that it comprises a machine sliver dip. up to 40% by weight; wheat gluten 14 to 19%; and lysine 1% by weight.

By its effect, the protein concentrate is equal to the conventional soybean extracted scrap, the use of which is preferable. It is more affordable and hungry, it is the use of domestic raw materials, so the soybean is not to be imported in higher latitudes. Soy protein is more valuable for human nutrition. The physical concentration of the concentrate is suitable for mixing into complete feed mixtures. The bulk of the raw materials used are by-products in the production of the main product.

The protein concentrate is an analogue of the multi-component premixes of vitamin or mineral as they contain the components of the type in an optimally balanced ratio.

The specific composition of the protein concentrate is illustrated by the examples which illustrate but not limit the invention. Effects of Protein Concentrate Tested on Fattening Chickens where feed mixtures with soybean extracted scrap served as a control. Example 1

Protein concentrate was mixed in these ratios (% by weight): machine slug flour 40% wheat gluten 19% fibulin (19.6% N-matter 20% corn molding 20% L-lysine 1%

N-content (analysis): 43.0%.

This concentrate was used as part of a complete two-feed feed mixture for chickens for fattening to 21 and 21 days. The composition of the feed mixtures of the components and the results of the analysis of the contents of the basic nutrients are given in Table 1.

By comparing the examples, it can be seen that the raw materials with variable content of N-substances (fibulin in Example 2 were substantially improved) can also be incorporated in such a way that the resulting composition and feed efficiency are maintained. Fibulin is also interchangeable with other types of feed yeast, e.g. torulou. The invention will find application in agriculture, respectively. in the feed industry to prepare compound feed. Although it is mainly designed for poultry, especially fattening turkeys, on which it was also tested, it could also be used for mixtures for pigs.
