Most farms are now breeding sows procedure has a certain range, which means day Food and feeding standards differ in the difference between the pigs. However, the basic objectives of the sow feeding system are the same. The article will explain why feed will rise and decline in some special stages, and relationships with performance or production goals. Readers can also compare with your company’s existing sow feeding systems and discuss their different places together with the supervisor.

The feeding management system of the mother pig will affect the production and profit of a pig farm. Therefore, it is important to understand the main principles and actual feeding, which helps the breeders’ flexible use.

First of all, we must know that the diet we use now is made by nutrition experts in consideration of modern nutritional principles and climate, such as raw materials, pig types, climate and circle conditions. Similarly, the feeding standards of each pig farm should also be determined by nutritional experts. Currently, in certain aspects of feeding and nutrition, especially the nutrients and feeding of resembled mother pigs.

Second, it is to understand that the breeding of resembled mother pigs almost affects every aspect of the mother pig production, from the recipient ratio, the number of piglets, the piglets and the elimination rate and use of sows. Days, etc. The purpose of establishing a feeding management system in the farm is to ensure that there is a relatively long production period (at least five births) after entering the breeding group, and maintains healthy and produces piglets at the lowest cost.

The feeding management system

The reserve sow and the mother pig feed system must be explained in some specialWhy is the specific feeding amount to be given. It should be understood that it is the most important thing about determining that feeding is just a boot. The relationship between each stage of feeding process is most important. As the saying goes, “seeing the fence” is to ensure that most of the mother pigs in the pregnancy until 90 days are in a suitable three-point love.
The first breeding before breeding:

Modern gene improvement has made breakthroughs in reducing fat and improving feed utilization, which will mean low fat backbits Pigs and produced sows are more susceptible to nutrients and feed. Therefore, when the reserve sow is raised to the third child, its goal is to reduce the loss of sows and increase the number of products.

The main purpose of the first breeding before the rear sow is to achieve a suitable weight and back thick thickness during breeding. It is generally believed that the rear sow is in the body weight of 130-140kg, and the breeding is the most appropriate when the back is 16-18mm. The rear sow is absolutely impossible when the weight is less than 130kg. Because of the reduction in the germaries, it is now more delayed, that is, the rear collective sow is in the third time of estrus, which makes the reserve sow need more fat reserves, improve the production Number, extend the useful life. The reserve sow in Europe is often around 100kg, and the back is sold from a pig farm. It is generally domesticated to accommodate in the 7-8 weeks of the field, which makes it needed to achieve the weight and back.
The sexual maturation of the rear sow should be paid attention to. Studies have shown that feeding in the birthplace is smaller. The reserve sow has been free to eat freely before the selection. If possible, each mens can be completed, or it can be fed about 3kg or fed according to appetite. The reserve mother pig should use the rear preparation of the sun according to the company’s system. These fluorescent energy is high, but the protein level is low, which can be used to increase back thick instead of muscle growth.

The feeding level will affect the first estrus and ovulation in the future. Therefore, the number of eradications of the sow is not a limiting factor affecting the number of pins. The number of ovoes in the rear bonding pigs, productionThe number will be more.
Hypothesis is referred to as a result of increased the amount of feed 10-14 days before the breeding of the rear sow, thereby obtaining the maximum number of ovulation. Usually 10-14 days prior to breeding, it can be achieved by free feeding, or the system arrangements will be reduced to 2.5kg after the second estrus, and then freely in the third estrus. Estate until breeding. This requires a detailed reserve sow estrus logging as a support.

1. Weaning to a breeding:

The sow during the breastfeeding should maximize the amount of milk and minimalize weight and back. Thick. When the piglet is weaning, the stop and breast pressure increase in sucking stimulation can cause lachera. The change in hormones in vivo can lead to the estrus of the sow, which increases the amount of feed will accelerate dry milk this stage to help reduce the interval of weaning to the breeding, increase the number of ovulation and the rate of fetus.

It should be kept to the breeding interval to the breeding interval on the breeding of the shakhophage, and 95% of the sow should be emotionally populated within 7 days after weaning. Feed as close as possible to its appetite. The first frying sow is in the range of 2.7-3.0 kg per day, which can be added to 4.0-4.5 kg from the sow. In the clustered circle bar, it should be used to achieve this goal and can deal with changes in appetite.

The interval of young mother pigs to breeding is longer than the old mother, and can shorten the weaning to breeding interval by improving the intake of breeding nutrients (if it is a tire steamed bun, you can formulate special young mother pig feeds) . Some experiments show that the high-quality diet of head fetal mother pigs feeding growth pigs or feeding all fat soybeans or adding fishmel will have a positive impact.

2. Fraction to pregnancy 21 days:
About the early pregnancy levels will affect the survival rate of embryos is the focus of past debates. Feeds in this period will play a decisive role in embryonic implantation. The failure of embryonic bedding is an important reason for the potential losses between the fertile eggs and the number of production. Some studies have shown that low feedThe amount of material level (about 1.8kg of the reserve sow, 2.1kg of the sow) can effectively improve the embryonic survival rate.

Most studies have shown that feeding within 4 days after the prevention is important. If the sow still maintains a good physical condition, that is, 2.5-3.0 points, the feed method during this period is to reduce the amount of feeding to 21 days of pregnancy. However, the sow of the body condition should increase the level of feed. On-site suggestion is divided into 2.8kg daily. The physical condition score is 1 Path to feed 3.4kg every day, which lasts for 60 days to the second physical condition score, which can ensure that the thinner sow is restored, and the required situation is reached during childbirth.

3. Pregnancy 22 days – 90 days:

The purpose of this pregnancy is to ensure that the sow is appropriate when childbirth condition. In the last 3 days of pregnancy, the growth rate of the fetus has declined. Most sows still maintain the original feed volume to increase muscle and back. Therefore, for most mother pigs, it may be small feed levels. Changes will have a large impact on the physical condition. Young sows still need some feed in front of 3-4 birth to maintain growth, and some pig farms are determined according to fetal. In order to maintain a good physical condition, the feeding amount specified in the system is 2.3 kg of the reserve sow, 2.3 kg of the sow.

To ensure that the sow is reached during childbirthThe physical condition of the standard, the score of physical condition should continue during pregnancy, and according to the adjustment feeding level, the physical condition score is carried out twice, ie 28-35 days and 63-70 days in pregnancy. Unless the weight of the backpack is declining, there are very few rear sows to increase feed to achieve the use of physical conditions. However, if some pigs score is only 1-2 points, additional feed is required, and the score of the sow is 2.8kg / day, and the feeding amount of 1 point is 3.4kg / day. 80% of the sows in the middle of pregnancy should be 2.5-3.0.

4. Pregnancy 91-110 days:

in pregnancy The last three weeks, the fetal growth rate is very fast, and the nutrition in this stage needs to be increased. Studies have shown that if there is no additional feed, the sow and the storage of the sow and the protein are met to make up for energy. The feeding level recommended by the feeding system is 2.8kg / day of the backup sow, 3kg / day from the sow. Some experiments also show that this system will also increase the weight of piglets. Another study shows that increasing energy storage in piglets will increase the survival rate of piglets. It is obvious that the benefits of improving feeding during this period is obvious.

5. Pregnancy 111 days to childbirth:

Most pig farms, reserve sows or sows in pregnancy 111 days have been transferred to the production room . During this period, it should be handled according to the procedure. Of course, due to certain special reasons, the reserve sow is still in the pregnancy house for 110 days of the mother sow, its diet must be reduced to 1.8kg / day, because if you continue to maintain 2.8-3.0kg / day feed level Resulting in the increase in deathplus.

6. Giving birth to weaning. 2 days before childbirth, according to the mother pigs, it is appropriate to reduce the feeding capacity (prenatal reduction), which can reduce the postpartum constipation, prevent uterine uterus, breast inflammation, and lack of milk syndrome, improvement. During lactation season. Do not feed the day, only bran soup is used. The second day after childbirth, gradually increased the pig feedstock, until it was free to eat. Calculation of feeding capacity of breastfeeding:

Pigramine milk is significantly related to the growth performance of commodity pigs. Studies have shown that weighing weight is 1kg, and the output time can be shortened by approximately 8 ~ 10 days. Feed efficiency is increased by 3% to 5%. Therefore, the weaning of the same aged piglet is larger, the better, most of the pig farms, piglets 25 days average It is already good to reach 8kg. Want to improve production results, according to energy conservation law, sow, how much feed can eat a few feeds per day to make piglets 25 days broken milk reached 9kg? The following algorithm is for reference only.

11 heads in each nest, and the production performance of 9kg per hour is over 25 days. Calculation with the weight of the primary piglet weight 1.5kg, the total weight of the pigs in breastfeeding is: 11 × (9- 1.5) = 82.5kg. These weight-g weight of nutrients have milk (feed conversion and weight consumption) and teachings. According to the teachings of 600g quality, the teachings of 600g of quality can bring about 600 g / head; the remaining 75.9 kg weight loss (82.5 -11 × 0.6 = 75.9), all from the breast milk.

The study shows that each kg breast is about 200g of dry matter (55g crude protein, 50g lactose,80g fat, 5.4mj / kgme). The piglets need to be 12MJ per weight 1kg, and the amino acid composition of the breast milk is very balanced, so the piglets need 4kg breast milk every 1 kg of piglets (22 / 5.4 = 4). 331.2kg breast milk (75.9 × 4 = 303.6) was required.

A 200kg heavy sow, mammal period weight consumption of 10%, namely 20kg. According to each consumption of 1kg body weight, 25 kg can be produced. The remaining 263.6 kg of breast milk (303.6 – 40 = 263.6), the feed of all sources of sow were feeding feed. Typical diet of breastfeeding is a grain and plant protein composition, with a metabolic energy of 14 mJ per kilogram. The efficiency of feed energy is about 70%, which means that the sow can produce a 9.8 mJME per milk for 1 kg of feed each pig. That is, the sow can produce approximately 1.8 kg of milk (9.8 / 5.4 = 1.8) each by 1 kg of feed in addition to the need for maintenance needs. A total of approximately 146.44 kg (263.6 / 1.8 = 146.44) was required, and the average daily required 5.86 kg (146.44 / 25 = 5.86) feed is used to lactate. The daily maintenance required by the sow is approximately 1% of the sow, and a 200kg sow, a 2kg feed is required for maintenance.

In summary, a pig with 11 pigs with 11 pigs, to reach a grade of 9kg of 9kg 25 days, and the sow is done in 20kg, each piglet is 600g The average daily feeding capacity of the sow needs to be 7.86 kg (2 + 5.86 = 7.86). It can also be simplified as a formula: the amount of breastfeeding is = 2kg + n x0.613, and n is the number of wear pigs.

So, please take all measures to improve the feeding volume of the mother pig breastfeeding, so that the average daily feeding capacity of the sow reaches 7.8kg to achieve your expectant piglets.

Other factors affecting the level of feed:
Pig varieties or lines: different types of pigs (genotypes) have different. For example, hybrid Dolock varieties will be more than other products.The appetite is strong. Some pig farms provide a nutritional indicators and recommended feed levels suitable for their purebred pigs, and each pig farm can also be adjusted.

Temporary: The previous mention of the growth of the sow will last until 3-4 tires. This is easy to link with modern feeding systems, such as the electronic feeding of the gang pig sow, the difference in the diet will be small, but most pig farms do not have equipment conditions difficult to apply in practice. The production site is adjusted according to the periodic physical condition score to achieve the same purpose. Similarly, young sows maintain the desired nutrients than the old sow, so if the fetal sow is feeding isometric feed, youth sows will get more feed for growth.

The European Pig Farm is supporting the orchard
Environment: the environment is also the main factor affecting the amount of feed. Most of the feeding levels are determined according to the demand of the pig at suitability. Additional feed is required for additional feed to maintain body temperature when the temperature is below the optimal temperature of the pig. When the pig is consumed by the energy insulation, its body and the energy needed with the fetus are consumed. Different types of circles, its temperature is not good, feeding levels need to be adjusted. Winter should increase the level of feed. It is recommended that every less than comfort temperature (21 ° C is a comfortable temperature of pigs) 3 ° C. Adjustment of feed is 0.14 kg / day in the reserve sow, 0.20kg / day by pig.
In addition, the high temperature in the summer will also affect feeding. Summer is desirable because of the decline in the lactation period, the body of sows may be poor than the winter. This requires that the amount of feeding in pregnancy must be increased so that the physical condition can be achieved in the next childbirth. Of course, you can also use a cooling system to avoid, because the increase in the amount of feeding during the lactation period is the key to the success and high productivity of the feeding system.

Standard reserve mother pig feeding procedures:

Note that it is assumed here: Rear Supply Sigs transferred into the back of the pig house after weight 100kg, adapt to 7-8 weeks after the third During the time of estrus.
1. When the mother pig is ready to enter the mother pig houseTo be free to feed, at least 3kg should be fed at least every day before the second estrus.
2. When more than 50% of the sows in the group have the second estrus, the feed level is reduced to 2.5 kg per day.
3. In 14 days before the third estrus, the feeding level is raised to free seeding level or at least 3kg per day.
4. The feeding level will drop to 1.8kg daily on the day after the last generation or product, until 21 days after breeding.
5. From the 22nd day after breeding, the feeding amount will be raised to 2.1kg

6. When the first physical condition (28-35 days of pregnancy) is fed according to the score Level:

The evaluation is 3 or more, maintaining the amount of 2.1kg / day

, raising the feeding amount to 2.3kg / day

The evaluation is divided into 1 point, and the feeding amount is increased to 2.5kg / day

Remarks: The physical condition score of the rear sow is generally less than 2 points unless it is in a sick state.

European environmental attention is very important, but it is still fermented and returned to the main

7. When the second physical condition (pregnancy 63- 70 days) According to the score, the feeding level is adjusted

8. The feeding amount will be raised to 2.8kg daily

9. When the pregnancy is 110 days, if still in pregnancy The feeding amount should be taken automatically to 1.8kg

10. When the pregnancy, the circle temperature is lower than the optimal temperature (the reserve sow is fed in the raised race ” It is said that it is approximately 21 ° C), and 0.14 kg is added to each day every day by 3 ° C.

1500 master pig farms, appearance looks very common

Sour of sows:

1. Weaning mother pigs are free to feed in the pregnancy house or feeding according to appetite, and the sow should be eaten as possible without waste.

2. On the same day of last 1, the day:

The sow of the three-minute separate is reduced to 2.1kg per day until 21 after breeding Day;

The sow scored 2 points increased the amount of feeding to 2.8kg / day until the first physical condition (28-35 days of pregnancy);

The amount of feeding is raised to 3.4kg / day until the first physical condition is measured.

3. In the 22nd day of pregnancy, the feeding amount of the sow to 3 is increased to 2.3kg
4. 1 at the first time The physical condition score (28-35 days of pregnancy) is adjusted according to the score:

The evaluation is 3 points, maintains 2.3kg feeding daily;

2 points, raised the amount of feeding to 2.8kg;

The evaluation is 1 point, and the feed amount is increased to 3.4 kg.

5. When scored in the second physical condition (63-70 days in pregnancy), the feeding level is adjusted according to the score

6. Improve the feeding level to 3kg at 91 days of pregnancy

7. If the sow is still in pregnancy at 110 days, the feeding amount should be reduced to 1.8kg 8. When the pregnancy is lower than the optimal temperature ( Feeding the sow in the shampoo limit column for 21oC),Each reduction of 3OC needs to increase the amount of feeding of 0.2 kg.
