Description

The invention relates to veterinary medicine, relates to biologically active feed additives and can be used to increase the growth energy and the safety of young chickens.

The complete feeding of farm animals and poultry using protein-vitamin supplements with macro- and microelements is one of the main factors that have a decisive influence on the realization of the genetic potential of their productivity.

It is known to use as food additives for poultry waste from food industry enterprises (for example, beet pulp, distillery stillage, fodder flour from grape marc, from waste from processing seeds of rice, buckwheat, barley, oats, millet, sunflower, etc. [1 ].

As a preferred analogue, we consider a feed additive for poultry based on powder of pine nutshell [2]. Pine nut shell powder (CED) is a complex natural organomineral complex that includes several tens of various chemical compounds in a bioavailable form. A significant contribution to the overall pharmacological effect is made by carbohydrates represented by poly- (fiber, pectin substances) and monosaccharides, trace elements, in particular manganese (6000 mg / kg), zinc (3500 mg / kg), copper (2600 mg / kg), silicon (5000 mg / kg), aluminum (7000 mg / kg), nickel (2500 mg / kg), lipids represented by unsaturated fatty acids that accelerate oxidative processes in body tissues (linoleic and linolenic), and vitamins F and P. However, the effectiveness this supplement is limited by the lack of vitamins, in particular groups B, C, E, which enhance functional activity of trace elements, manifested in almost all metabolic reactions.

The purpose of the invention is the stimulation of growth energy of young chickens.

The goal is achieved by a feed additive containing pine nutshell powder (CKO), thistle seed flour (Silybum mariaia), succinic, citric and ascorbic acid in the following ratio of ingredients, wt.%:

pine nutshell powder 47.5-48.0 milk thistle seed flour 47.5-48.0 succinic acid 2.4-2.6 vitamin C 0.6-0.7 lemon acid 1.0-1.7

Table 1 shows the variants of the claimed feed additives, including ratios with different amounts of the starting components. Each variant of the feed additive was tested on a separate group of broiler chickens at the age of 4 days, selected by the principle of analogues, at a dose of 0.4% of the main diet in two courses from 4 to 13 and from 24 to 33 days of life. One group served as control. Efficiency was determined based on clinical examination data. The results are presented in table 2.

As can be seen from table 2, the ratio of the initial components of the compositions 1 and 4 are impractical due to inadequacy of costs. The optimal ratio of the starting components of composition 2.

The invention is illustrated by examples.

Example 1. The effect of the feed additive on the biochemical parameters of the blood and on the indicators of natural resistance was evaluated in an experiment on egg cross chickens in a scientific and production experiment. The young animals selected by the method of analogues for the experiment were divided into two groups — the experimental and control. All chickens were kept in similar conditions, optimal in temperature, lighting, ventilation, and received compound feed according to the standards of VNITIP (2000). In the experimental group, chickens with the main ration were fed a feed additive in accordance with the invention (composition 2) in the following ratio of components, wt.%: SKO - 47.5; spotted milk thistle - 47.5; succinic acid - 2.6; ascorbic acid - 0.7; citric acid - 1.7, at a dose of 0.4% in two courses from 4 to 13 and from 24 to 33 days of life. The results are presented in table 3.

As can be seen from table 3, the claimed feed additive had a positive effect on the basic biochemical and indicators of natural resistance.

Example 2. The effectiveness of the claimed feed additives in comparison with the known analogues was evaluated in an experiment on egg cross chickens in a scientific and production experiment. The young animals selected by the method of analogues for the experiment were divided into three groups. In one control group, chickens from daily to 30 days of age additionally received RMS - at a dose of 0.3 g / kg body weight, in another control group, chickens did not receive additional drugs, and in the experimental group the declared feed additive, as in example 1 . During the experiment, to assess the state of the livestock, productivity indicators were taken into account. The results are presented in table 4.

From table 4 it is seen that the claimed feed additive not only contributed to an increase in the adaptive abilities of chickens, which was expressed in an increase in their live weight and safety, but also its prolonged effect was observed, which was expressed in an increase in productive qualities.

Example 3. The effectiveness of the claimed feed additives in comparison with known analogues was evaluated in an experiment on broiler chickens in a scientific and production experiment. The young animals selected by the method of analogues for the experiment were divided into three groups. In one control group, chickens from daily to 30 days of age additionally received RMS - at a dose of 0.3 g / kg of live weight, in the other control group, chickens did not receive additional drugs, and in the experimental group the declared feed additive, as in example 1 During the experiment, to assess the state of the livestock, productivity indicators and blood biochemical parameters at the age of 49 days were taken into account. The results are presented in tables 5 and 6.

Studies have confirmed that the claimed feed supplement stimulates growth energy and increases the safety of young chickens. The regulation of metabolic processes and the body's natural resistance when using a growth-promoting feed supplement containing SKO, thistle seed flour, succinic, ascorbic and citric acid occurs within physiological limits that do not cause any negative changes in the body, which is reflected in an increase in productivity and preservation .
