WITH

The invention relates to the physiology of farm animals, in particular the physiology of reproductive processes, and can be used to assess the reproductive function of pigs.

The aim of the invention is to simplify the method for assessing the readiness of sows for reproductive function.

This goal is achieved by the fact that before sowing, sows are administered intramuscularly in the area of the ear root 5% alcohol setting of iodine in a dose of 1.0-1.5 ml and after 10-15 minutes on the difference in body temperature before and after the introduction of

for 45-50 minutes, the degree of readiness of sows for insemination is judged.

The level of temperature increase depends on the level of energy and plastic substances in the body, therefore, according to the increase in total body temperature, sows are ready to perform reproductive function.

Sows, in which 10–15 minutes after the injection of 1.0–1.5 ml of 5% alcoholic iodine tincture, the body temperature rises by 0.5 ° C and higher, have a high level of plastic and energy substances in the body, therefore

It can be concluded that sows are ready for reproductive function.

Sows that have no body temperature rise after 10–15 minutes or increase by no more than 0.2 ° C have a low level of plastic and energetic substances in the body. These sows are not ready for the reproductive function.

Sows, in which the body temperature rises by 0.3-0.4 ° C for the administration of the drug, have an average level of plastic and energetic substances in the body, this level is not sufficient to ensure normal fruiting and lactation. Such sows are also recognized as not ready for reproduction.

Example 1. In the area of idle sows from the number of repairing pigs aged 10 months with a body weight of 125 kg, obtained by industrial crossing of sows of a large white breed with landrace breeds, according to the principle of analogs, 7 groups of 10 heads each were formed. All sows were injected intramuscularly in the area of the root of the ear. 5% alcoholic tincture of iodine with a Shilov semi-automatic syringe in doses in the first group of 0.3 ml, the second 0.5 ml, the third 0.8 ml, the fourth 1.0 ml, half the ml, the sixth 2.0 ml, seventh 3.0 ml. Body temperature was measured rectally by an RT-01 electrothermometer after 5,10,15,20,30,50,60,120 min from the moment of drug administration.

Repair pigs for these purposes are the most appropriate, as they have the same age, equal body weight, factory condition, not used for reproduction. This causes a high level of plastic and energetic substances in their bodies.

The research results are presented in table.1.

From the data obtained it can be seen that 5% - for iodine adjustment, administered intramuscularly, causes an increase in total body temperature. The nature of the temperature reaction depends on the dose of the drug. Thus, at a dose of 0.3 ml, it causes a short-term and insignificant rise in temperature, and at doses of 0.5-1.5 ml, it causes a fast and maximum temperature reaction. The maximum rise occurs by the 10th minute and is maintained, depending on the dose, from 20 to 60 minutes from the moment of administration. Then there is a gradual decline.

At doses above 1.5 ml, it causes a rapid, but less pronounced increase in the overall temperature.

Thus, the optimal dose for determining the level of maximum body temperature rise, the time of occurrence and the duration

the preservation reaction is 1.0-1.5 ml. At these doses, 5% tincture of iodine causes, after 10 minutes, a rise in body temperature of 0.5 ° C and higher, which persists up to 60 minutes from the moment of administration. In these doses,

Parath causes less painful reactions of animals.

Example 2. With the purpose of revealing the correspondence of the magnitude of the increase in the total body temperature for the introduction of 5% tincture i of iodine with the level of

Blood plastic and energetic substances experiments were performed on the main sows.

At the pig farm them. 60 years of the USSR, Etkulsky district, Chelba oblast, the main sows in the idle state, in the amount of 100 heads, rectally measured the general body temperature of the body with an RT-01 electrothermometer before insemination, then

intramuscularly in the area of the root of the ear introduced a 5% alcohol tincture of iodine in the amount of 1 ml. After 10 minutes, body temperature was measured again. Depending on the level of increase in the body temperature, the animals were conditionally divided into three groups, not changing the conditions of keeping and feeding. The first group included sows, in which the temperature response was absent or increased by no more than 0.2 ° C, there were

8 heads or 8%. The second group carried animals with a temperature rise of 0.3-0.4 ° C, there were 62 heads, the third group carried animals with a body temperature rise of 0.5 ° C and higher, there were 30 heads

or 30%. Then, 10 sows from each group received blood for testing. After that, the sows were inseminated.

The blood examined the content of plastic and energetic substances (Table.

2).

From the obtained results it can be seen that sows, whose temperature response to the introduction of the drug increased by 0.5 ° C and higher, had a level of indicators

the content of plastic and energy substances was significantly higher than that of sows that did not show an increase in body temperature or showed no higher than 0.2 ° C.

Thus, the total protein content was higher by 18.2, alpha globulin 2.4, gamma, globulin 2.0, total lipids 55.2%, cholesterol twice, glucose 44.0%, ATP three times, vitamin A 97.5, C 67.1, sodium 13.0, potassium 38.7, calcium 44.4, inorganic phosphorus 66.6, organic phosphorus 77.7, magnesium 56.5, iron 41.7, copper 79 ,9%.

In animals of the second group, the values of indicators of the content of plastic and energetic substances occupied the average position between the indicators in animals of the first and third groups, however, they significantly differed from those in sows in the first group.

Thus, the analysis of the obtained results suggests that the level of the body temperature response of sows to the introduction of 5% iodine tincture reliably corresponds to the level of plastic and energy substances in their bodies.

Example 3. In order to detect the level of the body temperature response of highly productive sows to the introduction of 5% iodine tincture, to demonstrate their subsequent productivity, the following observations were made.

At the pig farm with a capacity of 108 thousand hours of pigs per year of the sovkhoz state farm. 60 years of the USSR, in the workshop of single sows picked up 60 animals, which showed high productivity after the first farrowing. Before insemination in sows, TepMON et Ј I / y of the body was carried out with an RT-01 electrothermometer, then intramuscularly in the root of the ear was injected with a semi-automatic syringe of 1 ml of 5% iodine tincture. 10-15 minutes after the administration, the total body temperature was again measured and the level of the temperature reaction was determined. Depending on the level of increase in body temperature, the animals were divided into three groups. The first group included sows, in which the temperature response to the drug was absent or increased by no more than 0.2 ° C, there were 10 goals. The second group included animals with a temperature increase of 0.3-0.4 ° C, there were 30 such animals. The third group included animals with an increase in body temperature of 0.5 ° C and above, there were 20 of them. After the survey, all sows were determined to be productive.

The results of the observations are presented in table. 3

From the obtained results it can be seen that the productivity itself was low in animals that did not show

temperature reaction or not higher than 0.2 ° C.

Sows that reacted with a maximum temperature increase had

higher productivity. Thus, in litters of such sows, live piglets were more by 11.2, physiological mature 36.6, weight of a newborn pig was 17.3, litter 19.6%, less than stillborn by 67.0, physiologically immature 58.6%. By weaning, preservation was 90.9% and was higher than that of the sows in the first group, by 12.3%, the weight of the pigs was 3.7, the nests 33.4%, which were stunted in growth

less by 9%.

Animals, in which the increase in body temperature was in the range of 0.3-0.4 ° C in terms of productivity, occupied a middle position between the first and second groups.

Thus, on the basis of the results of observations made, it can be concluded that the level of increase in the body temperature of sows for the introduction

5% tincture of iodine before insemination reliably corresponds to their level of subsequent productivity.

The advantages of the method are that it can be easily incorporated into industrial technology, it is simple to perform, is not labor-intensive, cheap, VOVOLAR can timely determine the degree of readiness of sows for the implementation of reproductive function, the level of reserve

stocks of plastic and energy substances, it is reasonable to use them, harmless to animals and performers.

Thanks to this method, it is possible to increase the birth of live pigs by 6.4%, or

0.64 piglets, physiologically mature 28.1, weight of newborn piglet 12.0, safety 9.9, output of pigs per sow per one farrow 1.3 heads, weight of the nest to volume 19.8%, reduce the amount

frost on 10.0, rejection of sows 12.0%.
