Abstract

The invention relates to agriculture and can be used in animal husbandry for feeding young pigs. The purpose of the invention is to increase the average daily growth and improve the quality of pork. Pigs there at the age of two months, during 2 months feed additives are added to the feed in the amount of 5-6.4% of the diet. The feed additive is a product of microbial origin and is a cell membrane that is a by-product of the production of fermentolizat biomass of microorganisms without membranes. Yeast cells grown on n-paraffins, ethanol, molasses, as well as bacteria grown on n-paraffins, natural gas, are used as a feed additive. The inclusion of a feed additive in the diet of pigs increases the average daily weight gain by 9-10% compared to using papriin, the ratio of meat to fat is 3.75-3.76 versus 2.76 in the control. 3 tab.

Description

The invention relates to agriculture: thu farm and can be used in animal husbandry for fattening young pigs.

The purpose of the invention is to increase the average daily gain of animals and improve the quality of pork by increasing the proportion of muscle tissue and reducing the proportion of fat.

Example 1. 20 heads of a large white breed at the age of 2 months. divided by analogy

into two groups - control and experienced with an equal number of bolettes and gilts. Animals are kept under the same conditions. The feed group of the experimental group of pigs is injected with a feed additive, which is a cell membrane obtained from the biomass of Candida maltosa yeast B-779 grown on n-paraffins. By tons of animals in bulk. Duration of experience 2 months. The composition and nutritional value of compound feeds for pigs are given in table 1.

Yu

Results of feeding the feeds there The feed supplement from the cell walls of the biomass of the yeast Candida maltosa 9 also shows average daily gains and feeds per 1 kg of the growth of live weight of pigs shown in Table 2.

As can be seen from the table, the average daily increase in animals in the experimental group was 9.7% higher than in the control group. At the same time, the cost of feed with the addition of the feed additive from the yeast cell membranes was 9.0% higher, and the expression is 14.0% lower than with the addition of paprina,

The ratio of lean meat to fat was in the experience of 3.76 kg of meat per 1 dsg of fat, and in the control 2.76 kg.

The average daily weight gain by a known method was 450 g, i.e. 12.1% less than the proposed method.

PRI mme R 2. According to the principle of knowledge, two groups (control and experimental) of a large white breed of up to 5 animals each are formed.

I

Animals are kept in individual

cages. Feed animals with animal feed of the same composition as in Example 1, except that in the test group of the piglet cell membranes were obtained from the biomass of Candida utilis yeast BWA-651 grown on ethanol.

Data on the average daily weight gain per unit of weight gain and the quality of animal meat are given in Table 3.

From the data in the table it is seen that the average daily gain of animals with the content in individual cells in the experimental group is 16.1% higher than in the control group. At the same time, the cost of feed per unit of growth in the experimental group is 11% lower than in the control group. The ratio of lean meat to fat in the experimental group was 3.77 kg of meat per 1 kg of fat, and in the control it was 2.76.

The average daily gain of pigs when used in the compound feed is 5 g of papine (by a known method), which is 23% less than when the feed additive from the cell membranes of yeast biomass is included in the feed.

EXAMPLE 3. The method is carried out analogously to example 1, except that two groups of large white breed of pigs of 10 heads are formed. Animals receive feed of the following composition, wt.%: Cell walls of bacterial biomass 5.4 Fish meal 5.0

Barley shredded 59.6 Wheat10.0

Corn 18,9

Mel0.8

Cooking salt 0.3 Vitamins and salts of trace elements are introduced into the feed as in Example 1.

Cell membranes are obtained from the biomass of bacteria Arthrobacter simplex BWA-712 grown on n-paraffins. The average daily weight gain in the experimental group of pigs was 509 g and the ratio of meat to fat was 3.45.

Example 4: The method is carried out analogously to example 1, except that animals receive feed of the following composition, wt%: Cell walls of bacterial biomass 5.0 Fish meal4.5

Barley shredded 61.0 Wheat10.0

Corn 18,4

Cooking salt 0.3 Vitamins and salts of microelements are introduced into the feed as in example 1. Cell membranes are obtained from the biomass of bacteria Methylococcus capsule BSB-874 grown on natural gas. The average daily weight gain in experimental animals was 494 g, the ratio of meat to fat was 3.34. Average daily gain when 450 grams of paprin are included in the ration, which is 10% less.

Cell membranes are a byproduct of the enzymatic hydrolysis of the biomass of microorganisms and are sediment after separation or filtration of the enzymatic hydrolyzate.

For inclusion in pig feed, batches of cell membranes obtained by the fermentation of various types of biomass are suitable, for example, Candida maltosa yeast grown on n-paraffins, Candida utilis grown on ethanol, Sacchoromyces cerevisiae, grown on molasses,

Acthrobacter simplex bacteria grown on n-paraffins Methylococcus papsulatus grown on natural gas.

Cell membranes are characterized by the following average chemical composition,%.
