RU2513181C1 - Fodder additive of fresh-water anadonta and unio genera seashells for laying hens - Google Patents

Abstract

FIELD: food industry.

SUBSTANCE: invention relates to farm industry and, in particular, may be used in poultry breeding during laying hens breeding. The biologically active fodder additive for hens consists of sunflower extraction cake, maize gluten, fresh-water Anadonta and Unio genera seashells shell crumb and meat, vitaminous grass meal based on camel thorn leaves and stems and culinary salt. All the components are taken at the specified ratio.

EFFECT: invention implementation ensures enhancement of hens preservation, body weight gain and egg-laying capacity, ensures reduction of the fodder expenditure on eggs formation, promotes increase of laying hens egg-laying capacity, allows to increase performance, quality of the products and reduce the poultry breeding prime cost due to the fodder usage in the ration.

Description

The present invention relates to agriculture and, in particular, can be used in poultry to increase egg production of laying hens.

Known biological active feed additive, including ingredients from plant materials. As a biologically active feed additive, seaweed kelp in its natural form is used in the amount of 3.5%, in dry amount - 4% per ton of feed and fed to chickens during all productive periods of their life. The use of the invention will increase the safety of chickens, weight gain, egg production, fertility, hatchability of eggs and reduce the cost of feed for the formation of eggs (RF Patent 2386344).

The disadvantages of this method are that the extraction of raw materials is difficult.

A well-known mineral-protein feed additive from freshwater mollusk zebra mussel (Application: 2008100729/13, 01/09/2008), the disadvantage of which is the use of chemicals in the manufacture of the additive, the high cost of the finished product, as well as the catch of zebra mussel from eutrophied reservoirs.

The objective of the invention is to increase the safety of chickens, weight gain, egg production, reduce the cost of feed for the formation of eggs.

The goal is achieved in that the feed additive consists of crushed shells and meat of freshwater mollusks of the genera Anadonta and Unio, sunflower meal, corn gluten, table salt, vitamin grass meal based on leaves and stems of camel spine, in the following ratio, wt.%: Crumb shells and meat of freshwater mollusks of the genera Anadonta and Unio - 30%; sunflower meal - 50%; corn gluten - 10%; table salt - 2%; vitamin grass meal based on leaves and stems of a camel thorn - 8%. Then proceed to mixing the components of the feed additive. All components of the mixture are thoroughly mixed together until a homogeneous mass is formed.

The obtained feed additive before feeding the bird must be mixed in a ratio of 1: 2 with grain, grain mixture and bran, root crops (ration per head / day).

To study the effect of the feed additive on the safety of chickens, weight gain, egg production, and lower feed costs for egg production, a scientific and economic experiment was conducted on chickens of the breed Highsex Brown at the age of 12 months. To conduct the experiment, three groups were formed, of which one control and 2 experimental (30 goals per group). The first experimental group of chickens was fed the feed of the main diet with the replacement of 50% of fishmeal with freshwater mollusk flour, and the second was introduced a feed supplement based on freshwater mollusk. The duration of the experiment was 30 days.

As a result of scientific and economic experiments on laying hens, the following results were obtained. In the diets of all groups of feeding the birds observed good feed eatability. At the same time, feed consumption remained unchanged in all experimental groups of poultry. Within 30 days, the safety of hens in the control group was 95.3%, 19.56 eggs were obtained for the average laying hen; in the first and second experimental groups, the safety of chickens was 97.6% and 98.2%, respectively, and the average egg production was 20.86 eggs in the first experimental group and 22.31 eggs in the second experimental group, respectively. The average daily weight gain was at the level of 5.57 ± 1.06 g in the control group; 6.29 ± 0.56 and 6.37 ± 0.64 g in the first and second experimental groups, respectively.

Thus, a food supplement for laying hens using feed crumbs of shells and freshwater mollusks of the genera Anadonta and Unio as a source of calcium, together with vitamin grass meal based on leaves and stalks of camel spines, can increase productivity, product quality, and reduce costs. growing poultry by using in their diet a profitable and balanced feed supplement.
