Abstract

The invention relates to animal husbandry. The aim of the invention is to increase the growth of animals. Biologically active substances are added to the basic ration, for which use a mixture of magnesium perchloric acid and the enzyme macerobacillin in a ratio of 1: 5-1: 10. Every day from 20–35 days of age for 2–5 months, the young feed adds this mixture to the diet in a dose of 300–650 mg / kg of feed. The use of this mixture allows to increase the average daily gain of animals by 20-39% compared with the control and reduce the cost of feed per unit increase by 17.6-26.5%. 6 tab.

(ABOUT

The invention relates to animal husbandry, in particular to methods for raising young farm animals.

The aim of the invention is to increase the growth of animals.

The invention is illustrated by the following examples.

PRI and MER 1. On a dairy farm were selected groups of tel t at the age of 30 days, with a live weight of 6 kg, in an amount of 1 + animals per group. During the whole experimental period, animals of the first group received the basic ration (RR) adopted in this household, the body of the second group received the RR plus a mixture of HCM and macerobacillin in a 1: 1 ratio at a dose of 150 mg / kg feed, and a third groups - PR plus a mixture in the ratio of 1: 5 at a dose of 300 and the fourth - at a ratio of 1:10

a dose of 600 mg / kg feed. The duration of the experiment is 158 days.

The research results are summarized in table. one.

As can be seen from the table. 1, the greatest effect was obtained when the ratio of components was 1: 5 at a dose of 300 mg of mixture per 1 kg of feed. At the same time, an additional gain for each head was 22 kg (with a ratio of 1:10 and a dose of 600 mg / kg - 17 kg, and with a ratio of 1: 1 and a dose of 150 mg / kg - only 2 kg).

Take p2. On the rabbit farm, bunnies were picked up at the age of 12 heads in each group.

Feed the animals rationed, all the same: for 10 days after weaning from females - granulated feed for rabbits in the amount of QS g / goal and hay 30 g / goal or

In the first experiment with a duration of 50 days, there were 6 groups of rabbits, the first of which received the basic ration (RR) indicated above, the second — RR plus the HKM preparation in a dose of 1 mg C10 per kg of live weight of the rabbits, a third of the RR plus HKM v. 3, fourth - 5, pt - 7 and pole - OR ip HCM at a dose of 10 mg / kg of animal weight.

The results of the experiment are given in table. 2

As can be seen from the table. 2, the greatest increase in rabbit was in the groups receiving HKM at a dose of 3 and 5 mg CU kg of live weight or 77-139 preparations per 1 kg of feed. Therefore, these doses of the HCM preparation should be considered optimal for animals.

The second experiment was conducted in two stages, the first of which is designed for the shortest period of use of the enzyme preparation of macerobacillin in the diet of animals, the second - for the largest.

In the first stage of the experiment, there were 6 groups of rabbits at the age of 35 days under observation. The first group of animals received the main ration (the same as in the first experiment) and served as a control, the second - in addition to the rathion received the enzyme preparation macerobacillin with an activity of 1000 units. 1 g at a dose of 0.1 g / kg of feed, a third at a dose of 0.3, a fourth - 0.6, a half - 0.7, a pole received an enzyme pectoameorin with the same activity at a dose of 0.3 g / kg stern. The duration of the experiment was 62 days.

The results of this experiment are shown in Table. 3

At the second stage, under the supervision there were 3 groups of animals, 30 animals each in a group at the age of days.

The first group of animals received the basic ration and served as a control for the second, in addition to the ration, received macerobacillin in a dose of 450 mg / kg of feed, and one third - a pectofoetidine with the same activity and dose. Duration of experience 5 months.

The results of the experiment are given on the table. .

The materials of the second experiment indicate that the introduction of

Moreover, the greatest effect was obtained with the two-month use of enzyme preparations, although their effectiveness was maintained throughout the entire period of breeding the animals until they were transferred to an adult herd (i.e., up to 5 months old).

It is characteristic that the enzyme preparation macerobacillin has a more pronounced growth-promoting activity than the well-known enzyme preparations (pectovamorin and pectofoetidine), and therefore it is advisable to use macerobacillin in the rabbit breeding to accelerate the cultivation of animals.

The third experiment was also carried out in two stages, the first of which is designed for the shortest period of use of the mixture of the above preparations, and the second - for the greatest.

At the first stage of the third experiment there was a group of animals aged 35–5 days. Animals of the first group received the basic ration and served as controls, the second group - the OR and the HKM preparation at a dose of 120 mg / kg of feed, the third - PR and macerobacillin at a dose of 0.3 g / kg of feed, the fourth - a mixture of these drugs in a 1: 7 ratio at a dose of 50 mg / kg feed. The duration of the experiment is 65 days.

The results of the experiment are given in table. five.

The data from this experiment suggest that, when breeding rabbits for two months, the greatest effect is obtained from a mixture of HCM and macerobacillin in a ratio of 1: 7 at a dose of +50 mg / kg of feed, animals are 33.9 times higher than controls, 20.2% higher than when using one HKM and 23.5 higher than when using one of macerobacillin.

In the second stage of the third experiment, 6 groups of rabbits were observed under the age of days. The first group received the basic ration and served as a control, the second additionally received a mixture of HCM with macerobacillin in a ratio of 1: t at a dose of 270 mg / kg of feed, a third in a ratio of 1: 5 at a dose of 300 mg / kg, and a quarter respectively 1: 7 at a dose of 50, pta - 1:10 at a dose of 650, and a pole - at a ratio of 1:11 at a dose of 700 mg / kg of feed. The duration of the experiment is 150 days.

The results of the experiment are given in table. 6

The materials of the third experiment indicate that the mixture of HKM preparations with macerobacillus gives a significantly greater effect than when using each drug separately, and the greatest effect occurs during the two-month use of these drugs, but also at 5 months their efficacy is maintained, although it is reduced compared to two months of use. The greatest effect was achieved when using drugs in the ratio of 1: 5-1: 10 at a dose of 300-650 mg / kmbi feed.

The use of this mixture allows you to increase the average daily increase
