Abstract

The invention relates to agriculture and can be used in pig production for the prevention and reduction of stress in pigs during their rearrangement and transportation. The purpose of the invention is to reduce the loss of animal productivity. The introduction of prescription SC-28 sodium sulfate in the compound feed for pigs at a dose of 20-82 mg per 1 kg of live weight for 2-3 days before and 15-20 days after transferring to fattening provides a gain of live weight up to 110.4-116.2 % compared with the control group that did not receive the drug. The inclusion of sodium sulfate in the compound feed recipe SC-33 for 2-3 days before transporting pigs in the amount of 40-52 mg per 1 kg of live weight increases the mass of paired carcasses by 0.9-2.7 kg, and the slaughter yield by 1.1 -1.7% compared with the control group. 6 tab.

Description

The invention relates to agriculture and can be used in pig breeding for carrying out prevention and relieving stress in pigs during their rearrangement and transportation.

The purpose of the invention is to reduce body weight loss.

Example 1. The first series of three experiments was carried out to study the timing and doses of sodium hydrochloride intake in the diet when transferring pigs for fattening.

In the first experiment, the duration of the introduction of sodium sulfate into the diet of pigs before transferring to fattening is studied. 6 groups of pigs with 23 heads in each are formed according to the principle of analogs (age, sex, breed, weight and growth energy). The preparation is administered once a day in the amount of 20 mg per I kg of live weight of pigs for I, 2, 3, 5 and 7 days. Control

a group of pigs does not receive the drug. Animals of all groups in the composition of the diet receive a complete feed of recipe SK - 28, which consists of the following components, wt.%: Corn 46,0; 19.0; wheat bran 15.0; soybean meal 7.0; herbs on flour 3.0; fishmeal 3.0; m juice (n-t-flour 1.0; hydrolysis yeast 3.0; tris-calcium phosphate 1.0; fodder chalk 0.5; salt 0.5; premix KC-4 -I.

The research results are shown in a table. I.

From the data table. I can see that the highest average daily gain in live weight was observed in pigs of the second and third experimental groups, which are fed the drug for 2 and 3 days before being fed to fattening.

In the second experiment, i duration of feeding the drug to pigs is determined.

after transfer to fattening. For this purpose, according to the analogy principle, 6 groups of pigs with 25 heads each are formed. Amber-acid sodium is introduced into the diet 1 time per day in an amount of 26 mg per 1 kg of body weight for 5, 10, 15, 20 and 25 days after conversion to fattening. The control group does not receive the drug. Animals of all groups receive compound feed recipe SC-28.

Re: 1ult | the experience is given in table. 2

From the data of x, given in table. 2, it can be seen that the greatest stimulating effect was observed in pigs 3 and 4 of the experimental groups, which, after transferring to fattening, were fed prenat for 15–20 days. With a small or large duration of feeding the pigs, the drug was transferred to fattening in them below.

In the third day, the optimal dose of sodium hydrochloride in the diet of cfinnei i is determined; I will reduce stress when preparing for 11e K water for fattening.

Sodium succinate is introduced into the feed for 3 days1 1 before and 15 days after non-breeding of pigs for fattening in the amount of 10, 20, and mg pa 1 KI is the live weight. The air temperature in the fattening unit is 18–20 ° C. Animals receive mixed fodder recipe SK 28.-

As can be seen from the data table. : 5, the most BiiicoKiie priusg1 1 live weight of pigs for 45 days after the transfer to the fattening was noted in stomachs 1 1 2 and 3 g of the ship’s feed, which receive ptarn) cpc, P11Y sodium in the amount of 20 p 32 mg per 1 K1 body weight.

Example. 2. Conducting a second series of experiments on the study of the optimal timing of n doses of sodium nitrate in the ration of pigs when preparing them for transportation (4 and 5 experience).

In the fourth experiment, in order to establish the optimal timing for the introduction of sodium hydrochloride in preparing pigs for transportation, 5 cBnneii groups of 25 1H each, in accordance with the principle of analogs, are formed. The animals get a ration, of states from the compound feed of Reneta (Ж i53 next) of the composition, May. - / o: corn 45.5; wheat 10.0; 20.0; wheat bran 10.0; sunflower nipOT 6.0; herbs on flour 2.0; p1 | bpa flour 1.5; yeast 1 prolysis 2.0; tricalcium phosphate 0.6; chalk feed 0.9; table salt 0.5; Premix COP - 4 1.0.

days, respectively, prior to transportation to the mill.

The results of the study are shown in Table. four.

As the results shown in table. 4, as a result of transportation and pre-slaughter fasting fasting in pigs of the experimental groups, differences in the slaughter yield and the mass of paired blunt animals are observed. The highest rates were found in animals of the third group, which were injected with the drug in the diet for 3 days.

In the fifth experiment, an optimal dose of sodium sulphate was determined for introduction into the ration of pigs and their preparation for transportation.

According to the analogy principle, 5 groups of pigs are formed, but 25 heads in each. Pig m is fed with a complete feed of recipe SK - 33. Sodium amber is introduced into the diet for 3 days before transporting to the m juice combine in doses of 20, 32, 40, 52, 68 mg pas 1 kg of live weight.

The research results are summarized in table. five.

The data table. 5 show that with almost the same live weight of pigs before transporting, the mass of paired carcasses of the 3 5 groups boomers by 0.9–2.7 kg, and the slaughter output of ibiHie by 1.1 is 1.7 / about what in the first group animals. The smallest losses of live weight and the weight of plants transported were 1eny in pigs of the fourth and fifth groups, who received sodium sulphate in the diet at a dose of 40–52 mg per 1 kg of body weight, and the duration of its introduction into the espionage was 2–3 dp.

Example 3. For a comparative assessment of the effectiveness of the anti-stress effect of fumaric acid and sodium sulphate in preparation for the transfer of pigs to fattening, they conduct scientific and production experience. According to the principle of analogs, 3 groups of pigs each form 25 pigs. The first group is koptrolna, does not receive drugs; the second is experimental, sodium amber sulphate in a dose of 30 mg / kg body weight is introduced into the diet within 3 days before and 15 days after the transfer to the fattening; one-third was experienced, fumaric acid was administered to the diet at a dose of 100 live weight during 10 days before and 10 days after the animal refused to feed the pigs.

The research results are summarized in table. 6

As can be seen pz data given in Table. 6, for the period of the experiment (25 days), the average daily weight gain in pigs of the BTopoi i group, in the diet of which sodium citrate was introduced, was significantly higher

compared with the control and third (treated with fumaric acid) groups of 13.9 and 6.8%, respectively.
