Abstract

FIELD: cattle breeding. ^ SUBSTANCE: method consists in adding of grinded spiny eleuterococus root to the feed in the ratio of 0.2 g per 1 kg of live weight and cellobacterine to the ratio of 0.02 g per 1 kg of live weight during the period of cattle's transition from milk to complex nutrition. For the calves the start of feeding of supplement corresponds to transition from skim milk or milk substitute feeding and the duration is 20 days. The piglets are fed with supplement starting with 8 day before planned weaning and finishing with 8 days after it. ^ EFFECT: invention allows increasing animal weight gain during long period after method application. ^ 3 cl, 4 dwg, 2 ex

Description

Designed to increase the meat production of enterprises for the cultivation of farm animals.

There is a wide variety of feed additives and methods of feeding them in order to increase the main indicators of meat breeds of livestock and poultry. Among them can be called a method [1], according to which at certain stages of the development of animals they add wheat germ to the feed with a set of macro- and microelements and vitamins. With a good positive effect of the method, its significant disadvantage is the complexity of the preparation of the additive and the high price of its constituent components.

The closest solution to the object of the invention (prototype) can be considered a feed additive made up of Doxipres and Tiamutin antibiotics along with Bazhedin filler, which is added to the nutrient substrate for 10 days when switching to another feed [2]. The disadvantage of this method is also the high price of the components.

The aim of the present invention was to significantly increase the weight gain of animals when used as a feed additive inexpensive publicly available components.

It turned out that the goal can be achieved by using an additive of only two components, namely the crushed root of prickly Eleutherococcus and the probiotic cellobacterin. Each of the components has a beneficial effect on the development of animals, but a significant increase in gain is achieved only with their combined action.

Studies have shown that the greatest gain is provided by daily feeding of 0.2 g of prickly Eleutherococcus root and 0.02 g of cellobacterin per 1 kg of live weight of the animal during the transition period from milk to complex nutrition for two to three weeks. For calves, the optimal start to this period was the moment of transition from feeding a dairy product or milk replacer, occurring at the age of about 4 months, and the best duration is 20 days. For piglets, feeding this feed additive is most effective to start 8 days before the planned weaning from the sow and within 8 days after.

Example 1

The tables in figure 1 and figure 2 show the test results of the claimed method on calves. Figure 1 shows the change in the indicators of blood tests in a 20-day period, corresponding to the addition of eleutherococcus with cellobacterin to the feed in experimental versions. It is clearly seen that the application of the method gives a significant effect. A decrease in blood levels of intracellular enzymes alanine aminotransferase (ALT) and aspartate aminotransferase (ACT) indicates a steady normalization of biochemical reactions in cells. An increase in plasma and red blood cell counts illustrates the acceleration of metabolic processes in the animal's body. Figure 2 shows the influence of the method on the dynamics of the calf gain for more than a year after feeding the additive at 4 months of age.

Example 2

In the tables of FIG. 3 and FIG. 4, the test results of the claimed method are given on sucking pigs. Figure 3 shows the comparative tests of the method at different principles of feeding the additive before weaning from the sow. It is clearly seen that the best results correspond to a period of 8 days. Figure 4 illustrates the prolonged effect of the method after 33 days on the increase in average live weight of piglets. It manifests itself in both absolute and average daily gain.

It should also be noted that the application of the claimed method increases the secretion of certain hormones, in particular growth hormone. In the subsequent period of life in calves and piglets, the mortality rate from diseases decreases and the safety of the livestock increases.

Additives used in the claimed invention are cheap and generally available, which ensures an increase in meat production while reducing its cost.

Claims (3)

1. A method of increasing the weight gain of animals, according to which, at certain stages of development, food is added to the feed, characterized in that during the transition from milk to complex nutrition, prickly Eleutherococcus root is added daily to the animal feed at the rate of 0.2 g per kg live weight and cellobacterin - based on 0.02 g per kg of live weight. 2. The method according to claim 1, characterized in that in calves the period of transition from dairy to complex nutrition is 20 days after cessation of feeding with a milk replacer or dairy product. 3. The method according to claim 1, characterized in that in suckling piglets, the period of transition from milk to complex nutrition is 16 days, including 8 days before the planned weaning from the sow and 8 days after.
