Abstract

The invention relates to agriculture, in particular to the intensive and resource-saving technology of preparing high-quality feed. The purpose of the invention is to improve the quality of the target product. For this, in the method of obtaining the feed additive from the pigment wastes for pigs by washing the raw material, grinding it, heat treating it and introducing the mineral additive, the mineral additive is introduced into the crushed leather waste before the heat treatment in the amount of 8-15% of the total mass, after heat treatment, beet pulp or silage of root and tuber crops is introduced into the resulting mass in a ratio of 1: 0.8 to 1.7, followed by stirring the mixture until a homogeneous mass is obtained. Moreover, tricalcium phosphate or trinethiri phosphate is used as a mineral additive. The invention makes it possible to increase the average daily gain in live weight of breeding gilts by 8–20%, the number of pigs in the nest — 11.2% of large-fruited children — by 4%, the milkiness of sows per 30 days — by 15%. 1 h p f-ly. 3 tab.

Description

The invention relates to agriculture, in particular to the intensive and resource-saving technology of preparing high-quality feed.

The purpose of the invention is to improve the quality of the target product by increasing the digestibility of total nitrogen in the daily rations of pigs and increasing their productivity.

PRI me R 1. Waste of non-salted pork skins with fat content of 57.4-59.7% after washing and cutting at the cutting site to pieces of 0.2-1.0 dm2 was supplied to the horizontal boiler KVM-4 6 into the horizontal boiler , installed on the leather factory. Extra waste of hides was tricalcium phosphate flour in the amount of 7% of the organic substances contained in them. Thermal

treatment was carried out at 135-140 ° C for 1.5 h. After that, moisture was evaporated from the processed semi-finished product by vacuum drying. Dry beet pulp was introduced into the dehydrated product in a mass ratio of 0.81 heat treated and dehydrated waste for 25 minutes using anti-rotating blade rotors of a horizontal boiler. Neutralization was achieved by the dry organic acids in the pulp. The resulting feed was used in scientific and economic experiments on pregnant and suckling sows.

In the control, non-salted pigskin wastes were processed in accordance with a known technical solution.

Example 2. Tanned wastes of cutting leather, bleached from aniline dyes, and not fat, were fed to a horizontal boiler KVM-4.6 installed at the feed factory of the pig complex using a bucket loader. Additionally, trisodium phosphate powder was added to the waste skin in an amount of 15% of the organic matter content. Further, the leather waste together with trisodium phosphate was moistened with water 1: 1. Thermochemical treatment was performed at 140 ° C for 3 hours. After that, the semi-finished product was cooled from 65 ° C and discharged from a horizontal boiler and fed to a C-30 continuous mixer, where the root-and-vegetable combisilos were fed in a ratio of 1.7: 1. Neutralization of alkalinity was achieved by combisilos organic acids. The resulting feed was used in scientific and economic experiments with bacon fattening of young pigs.

Combisilos is based on 85% carrots and 15% alfalfa flour.

In the control, the waste of the skins was processed in accordance with the known technical solution.

Example 3. Non-standard rejected sheep skins, after disintegration and decalting with fat content of 8–11%, were washed with water and chopped up at cutting site to pieces of 0.2–1.0 dm2. With the help of a fish pump, the wastes were loaded into a horizontal boiler KVM-4.6, installed in the feed shop of the pig complex. In addition, 11% of the content of & organic matter, a mixture of calcium and sodium phosphates in a 1: 1 molar ratio. Heat treatment was carried out at 135-140 ° C for 1.5 hours.

After that, the semi-finished product cooled to 65 ° C was unloaded from a horizontal boiler and fed to a C-30 continuous mixer, where, at a ratio of 1.25: 1, a combisilos was fed based on 85% sugar beet and 15% ground corn cobs. The resulting feed was used for breeding pigs. In the control, the waste of sheep skin was recycled in accordance with the known technical solution. Example 4. Three groups of pigs were selected, 25 animals each. The livestock of the basic groups, accepted as the standard, received standard feed, and the animals of the experimental groups were fed feed in the daily ration as a source of animal protein.

in accordance with example 1, the pigs of the control groups received a feed additive prepared in accordance with the known technical solution.

To study the effectiveness of the method and the resulting feed additive on pregnant and lactating sows, the standard compound feed SC-10 was used, containing fish and pasta

flour; in the control and experience, the last ingredients were replaced with a leather-based feed additive.

Table 1 shows the results of experiments on sows.

Studies have shown that when used in the daily ration of sows of the feed additive prepared according to the invention, the increase in live weight of the nest in 60 days was 50.1 kg more,

than by the known technical solution. To obtain the effectiveness of the feed additive prepared from tanned wastes of cut leather, K-56-1 and K-56-2 feeds containing reverse and fish meal were used; in the control and experience, these additives were replaced by a feed additive based on these wastes. The results of experiments on bacon pigs are given in p.2.

In diets for breeding pigs in groups, feed additives from sheep skin waste were introduced by analogy with a population of sows and bacon pigs. The results of the experiments are presented in

table.3.

The results of the studies given in Tables 2 and 3 show that the average daily gain in live weight of hogs and gilts was, respectively, by 0.106 kg and

0.103 kg higher than the known technical solution.

The invention allows to increase the average daily gain in live weight of breeding pigs by 8-20%, the number of pigs per

nest by 11%, large fruit by 4%, milk production of sows in 30 days by 15%.
