Abstract

The invention relates to agriculture and can be used in the poultry industry in the preparation of compound feeds for young agricultural birds. The purpose of the invention is to increase the increase in live weight of the bird. According to known methods, the content in grass meal from alfalfa saponins, cougestrol and formononetin is determined. The total amount of phytoestrogens is determined by recalculating formononetin to cougestrol, taking into account the fact that the latter is 133 times more active. After that, a phytoestrogen-saponin ratio is calculated. With a high phytoestrogen-saponin ratio in alfalfa flour, it is mixed with flour containing fewer saponins. The amount of phytoestrogens in grass meal from alfalfa increases in the budding phase, saponins in the flowering phase. Feeding chickens there with feedstuffs containing grass meal with phytoestrogen-saponin ratio 1: 1560 increases the increase in live weight by 104.5-108.6% compared to chickens that received grass meal with phytoestrogen-saponin ratio 1 : 2345-1: 3910. The cost of feed per 1 kg increase decreased to 98.1-89.3%, respectively. 3 tab.

Description

The invention relates to agriculture and can be used in fodder production, in particular in the preparation of feed for young poultry.

The purpose of the invention is to increase the increase in live weight of the bird.

Example 1. In the alfalfa flour, the content of biologically active substances s saponins, cougestrol and formone nonetin is determined by conventional methods.

Ciostrol and formicum oitoestrogens (Nonethes, differ in their biological activity (coumestrol is more than 133 times more active than formononetin), and therefore, to determine the total amount of phytoestrogens in alfalfa flour, the content of less active, such as formononetin, is more active, cumstrol, more active coumstrol is converted to content of phytoestrogen, more active coumstrol, 18% in cumestrol equivalents) according to the following formula:

After calculations, the phytoestrogen-saponin ratio in alfalfa flour is found to be 1: 2220 and, on the basis of this, it is established that the flour is unsuitable for feeding.

In another batch of alfalfa flour, after its analysis on the content of photoestrogens and saponins and the calculation of the phytoestrogen-saponin ratio, it is determined that it is 1: 510. Mix the two batches of alfalfa flour in equal amounts and get a mixture with a phytoestrogen-saponin ratio of 1: 1355. Such a ratio allows the use of flour with a high concentration of saponins while avoiding the loss of the live weight of the bird.

The data on the dependence of phytoestrogens and saponins in grass flour from alfalfa variety 30 Zaykevich on the vegetation phase are given in Table 1.

As can be seen from Table 1, the content of phytoestrogens (coumestrol and formono-35 netin) increases in the budding phase, in the flowering phase it decreases, the saponin content increases from the stem treatment phase to the flowering phase. The highest phytoestrogen-saponin 40 ratio is marked to the flowering phase.

Example 2. The effect of the phytoestromate-saponin ratio was determined on chickens of rsd island breed of 10 days of age, of which 4 groups of 60 animals each were formed using the analog method. Continued Indicators of the productivity of chickens depending on the Aito-estrogen-sapon new ratio in alfalfa flour are given in table 2.

As can be seen from Table 2, an increase in the α-phytoestrogen-saponin ratio leads to a decrease in the increase in the weight of chickens and an increase in the cost of feed per 1 kg of increase.

PRI me R 3. The experiment was conducted on day-to-day broiler chickens. Two groups (control and test), 200 animals each, are formed from day-old chickens of the Broiler 6 cross. Continuation of the experience of 49 days. In the first experiment, chickens of both groups get complete feed by adding 2-5% alfalfa flour, and the control group of chickens get alfalfa with Kumestrol-equivalent-saponin ratio (1: 3120) - (1: 3910), and. Experimental group - alfalfa flour with phytoestrogen-saponin ratio of 1: 1560.

In the second experiment, the chickens obtained adequate nutritionally combico as in the first experiment, but with the inclusion of 5-10% alfalfa flour. At the same time, the phytoestrogen-saponin ratio in the alfalfa flour in the control group was (1: 2345) - (1: 3120), and in the experimental group - not higher than 1: 1560. The effect of grass flour from alfalfa with different phytoestrogen-saponin ratio on the increase in live weight of chickens is given in table 3.

From the data in the table it can be seen that when included in the feed for broilers, 5-10% of grass meal and

The experience is 50 days. Chickens of control alfalfa from a phytoestrogen-saponin group (K) receive a complete feed with 3% alfalfa flour, which contained 5 mg of phytoestrogens (3.92 mg of cumestrol and 143 mg of formononetin, which is equivalent to more than 1.08 mg of cumestrol ) and 2.4 g of alfalfa saponins, Phytoestrogen-saponin ratio in alfalfa flour was 1: 480.i

the ratio of 1: 1560 average accurate weight gain increases to 104.5-108.6% compared with chickens that received grass meal with phytoestrogen with a saponin ratio of 1: 2345-1: 3120-1: 3910 the cost of feed per 1 kg of growth was reduced to 98, 89.3%, respectively.

Chickens of the experimental groups receive the same feed as the control group, but preliminarily include the purified preparation of saponins in alfalfa flour, thereby expanding the phytoestrogen-saponin ratio from 1: 480 to 1: 3200.

Chicken productivity, depending on the Aito-estrogen-saponine ratio in alfalfa flour, is given in Table 2.

As can be seen from Table 2, an increase in the α-phytoestrogen-saponin ratio leads to a decrease in the increase in live weight of chickens and an increase in the cost of feed per 1 kg of increase.

PRI me R 3. The experiment was conducted on day-to-day broiler chickens. Two groups (control and experimental) of 200 animals each are formed from daily chickens of the Broiler 6 cross. The duration of the experiment is 49 days. In the first experiment, the chickens of both groups receive a full ration feed with the addition of 2-5% alfalfa flour, and the control group of chickens with a feed of alfalfa nuku with kumestrol equivalent-saponin ratio (1: 3120) - (1: 3910), and. Experimental group - alfalfa flour with a phytoestrogen-saponin ratio of 1: 1560.

In the second experiment, the chickens of hectares receive an adequate nutritional feed, as in the first experiment, but with the inclusion of 5-10% alfalfa flour. At the same time, the phytoestrogen-saponin ratio in the alfalfa flour in the control group was (1: 2345) - (1: 3120), and in the experimental group - not higher than 1: 1560. The effect of grass meal from alfalfa with different phytoestrogen-saponin ratio on the increase in live weight of chickens is given in table 3.

From the data presented in the table, it can be seen that when broiler feed is included in feed, 5-10% of grass meal from

alfalfa with phytoestrogen-saponin

By a ratio of 1: 1560, the average daily weight gain increases to 104.5-108.6% compared to chickens that received grass meal with phytoestrogen-saponin ratio 1: 2345-1: 3120-1: 3910 as part of the feed. feed costs per 1 kg increase decreased to 98.1-89.3%, respectively.
