When do pregnant sows start to be fed?

It's never been reduced, when you're about to give birth.

The feeding of sows after pregnancy is determined according to the amount of food eaten by the sows, and in the early stage of pregnancy, it is generally about three to five catties. As the piglets grow, the amount of food the sow will also increase, and the amount of feed to the sow needs to be increased, and the nutrients and minerals will be increased. The fetal development of sows requires more nutrients to satisfy the sow, and the amount of sows a day at this time is about five or six catties.

The nutrients required by the sow after pregnancy will also increase, providing sufficient nutrients for the sow and promoting the development of the fetus.

First, the pregnant sow is fed a few catties of feed.

The amount of feed fed to sows after pregnancy should be determined according to the sow's fat condition and the sow's different stages of pregnancy. The daily feed amount before labor is about three catties to five catties. Later, if it is late, the amount of feed for the sow is about 3.5 to 4 catties.

The amount of feed per day for the five weeks after pregnancy is about two catties. The amount of feed per day for sows from six to thirteen weeks of gestation is two and a half catties, and after fourteen weeks.

The amount of feed for sows is three to five catties per day.

2. What sows need to pay attention to after pregnancy.

1. Pregnant sows must pay attention to nutrition, and breeders choose better nutritious feed when choosing feed. Strengthen the management of feed, and strictly control the quantity and quality of feed.

2. Epidemic prevention measures should be taken for pregnant sows. Vaccination in advance to prevent the appearance of sick pigs and improve the immunity of sows. Vitamins are added to the feed.

food, enhance physical fitness, do a good job of health care.

3. Do a good job of sanitation for sows after farrowing to ensure that sows have a comfortable environment. The breeder should carry out strict disinfection residue and timely ventilation of the pig house to ensure the environment in the pig house.

Dry and clean. 4. Pay attention to controlling the amount of feed for sows, don't give too much at one time, but a small amount many times. Pay attention to the drinking water of the sows, and prepare water around the pig house in time to avoid nutritional deficiencies caused by the sows not eating due to thirst.

How to feed sows after pregnancy, is it normal for sows to have secretions after pregnancy.

1. Early pregnancy: from the 21st day after breeding to the second day after breeding, the daily feeding amount during this period is the second trimester: refers to the 22nd to 84th days of pregnancy, and the daily feeding amount is, if the sow is thin, the daily feeding amount increases, and if the sow is fat, the daily feeding amount decreases in the late gestation:

Refers to 85 to 112 days of gestation, parparous sows are fed, gilts are fed 3kg.

1. How to feed sows after pregnancy.

1. Feeding amount.

According to the embryonic growth stage, it can be divided into three stages: early, middle and post, and the feeding amount is as follows:

1) Early pregnancy: It usually refers to the period from the time after mating to about the 21st day after mating, and the daily feeding amount is about that.

2) Second trimester: usually refers to the period from the 22nd day to the 84th day of pregnancy, the daily feeding amount is about that, if the sow is lean, the feeding amount can be increased on this basis, and if the sow is fat, it can be reduced on this basis.

3) Late gestation: usually refers to the period from the 85th day to the 112th day of pregnancy, if it is a multiparous sow, feed it every day, if it is a gilt, feed 3kg per day.

2. Feed formula.

1) Pre-pregnancy (mating to 80 days of pregnancy).

25% corn, 12% bran, stir-fried soybean meal, calcium hydrogen phosphate, salt additives.

Corn flour is 13 acorn, 3 wheat bran, 5 rice, 1 fish meal, 9 soybean cake, 1% salt additive of calcium phosphate powder.

10% soybean meal, 29% corn, 25% bran, 12% rice wheat bran, 1% bone meal, calcium hydrogen phosphate salt additives.

2) Late pregnancy (81 days of pregnancy to delivery).

Corn 23%, bran 13%, fried soybean meal with bran fish meal, calcium diphosphate salt additives.

During pregnancy, sows have a high demand for nutrients because they have to bear the growth and development of a large number of fetuses. Under normal circumstances, the feeding amount is low within 1 week of pregnancy, and it is not suitable to feed high-energy feed, otherwise it is easy to increase the mortality rate of fertilized eggs. After that, the feed rate is gradually increased until the feed is reduced 3 days before production.

The following specifies how much feed to be fed to the sows that are in the pigs.

1. Sows are fed kilograms of feed every day when they are pregnant for 100-111 days. The number of feedings is 2-3 times a day, and the feed type is the late feed of pregnant sows.

2. The mother Qi Ran pig is 112 days pregnant - fed 1-3 kg of feed per day during delivery. The number of feedings is 2-3 days, and the feed type is lactating sow feed. If the sow is unwilling to stand up to eat the feed during feeding, it is necessary to drive it away.

Pregnant sows are fed kg of feed 60-90 days after mating.

The 35-90 days of sow gestation is the period of growth, body reserve, and body size wheel adjustment and recovery, and the overweight or lean sows are appropriately reduced or fed to make the pregnant sows reach a good state before farrowing.

90 days of gestation – feed suckling sows kilogram of feed days. (Crude protein content of diet 16%) This stage is the rapid growth of late spikes and the growth period of mammary glands, it is recommended that both gilts and sows should be fed 9500 kcal digestive energy days.

As far as lean pigs are concerned, when feeding with full price pregnant sow feed, the first 30 days after pregnancy, the feeding amount should be controlled below kilograms, and in the future to 80 85 days of pregnancy, feed 2 kg per day, in the month before farrowing, the daily feeding amount increases to kilograms, and the week before farrowing can be changed to feed lactating sows, and the daily feeding amount is 3 4 kg (one or two days before farrowing), to ensure that there is a need to meet the growth and development of fetal pigs.

In the first trimester of gestation (indoctrination - 28 days), sows feed 4 kg per day.

First-parity sows are fed a diet of 21-28 days during the rearing phase after inbreeding, no more than 2 kg per day, and the maximum embryo survival rate is ensured.

In the second trimester of pregnancy (28-84 days), kilograms per day. Increase or decrease feed according to body condition. Based on a body condition score of 3 points, each increase of 1 point decreases the feed.

1. Weaning-breeding.

There are many pig farms that think that weaning to breeding is only a short 3-7 days, and it does not matter what feed is fed, and they start to use gestation sow feed when they enter the breeding house.

However, many trials have shown that the use of low-energy (low linoleic acid) low protein gestation sow feed can affect the number of ovulations of sows, which is one of the reasons for the decline in litter size, although the pre-breeding time is very short, and this effect will be even greater if the sow herd is thin.

2. Feeding should be strictly restricted within one week after breeding.

Because 48-72 hours after breeding is the stage of implantation of fertilized eggs into the uterus, if the feeding amount is too high, the daily feeding energy is too high, which will lead to an increase in embryonic death and a decrease in litter size;

Overfeeding is more likely to occur when the sow herd is lean.

If the sow herd is thin, the whole feeding amount can be adjusted at 7-37 days of gestation, and the adjustment range is kilogram days, which can not only make the sow body condition recover quickly, but also will not cause the problem of declining feed intake of lactating sows.

3. Feeding time for pregnant sows.

Most pig farms in Europe and the United States will limit feeding to the 95th-100th day of pregnancy, and then enter the late gestation feeding stage, and the old feeding method has been used in China, that is, the 84th day of pregnancy.

The study of the Pig Nutrition Group at the University of Kansas in the United States has confirmed that too early feeding time (84 days) in pregnant sows will lead to a decrease in the number of mammary cells in lactating sows, and the total amount of RNA in sows fed at 100 days of gestation is significantly higher than that in sows fed at 84 days.

Therefore, it is prudent to increase the size of the shed too early to affect the development of the sow's mammary glands, which is also an important reason for the decline in sow milk production and the small weaning weight of piglets.

4. The feeding of pregnant sows in the later stage is not accurate.

Everyone knows that this stage is very important, and the feeding of pregnant sows in the later stage is not accurate, resulting in a small newborn weight.

But there are two mistakes that are most likely to occur in the actual feeding process:

One is that the amount of feed is insufficient, and the other is the use of pregnant sow feeding.

Insufficient feeding is mainly due to the feeding too early (84 days) average 3 kg days, 100 days before gestation can also meet the basic nutritional needs of fetal weight gain, 100 days after the piglets into the rapid growth period, still 3 kg per day, do not change the type of feed continue to use pregnant sow feeding, it is difficult to meet the nutritional needs of the rapid growth of the fetus.

The correct practice is best to start feeding in 95 days, and it is best to use high-energy and high-protein lactating sow feed with oil or "pig special high linoleic acid fat powder", so that the formula standard of lactating sow feed can reach more than 3150 kcal and crude protein lysine content is not lower.

If you start feeding after 95 days, the amount of feeding must be accurately controlled. In order to effectively prevent dystocia, the amount of primiparous pigs should be controlled at 3 kg a day; 2. Sows with more than 2 farrows are not less than kilogram days; The feeding time is 95-112 days, and the pre-production material is reduced by 2 days.

Sows are fed 40 days before farrowing, 1kg of mixture 750kg, can be fed to the weaning period, can also be fed for a long time, a month to feed 15-20 days, greatly improve production performance and economic benefits.

Feeding standards for pregnant sows after breeding: Spike tour.

5 weeks a day. 13 weeks (menstrual day cautious, reserve day).

weeks (menstrual kg days reserve kg days).

weeks (menstrual kg days reserve kg days).

Zhou to labor (menstrual kg days, guess filial piety sales reserve days).

No, it won't. We know that these different raw material ratios are to meet the different nutritional needs of sows in two stages, and the sows need more protein feed during lactation, that is, the content of soybean meal will be higher, which is for the nutritional needs of sows to secrete milk, which can not only improve lactation yield, but also improve the quality of milk, ensure that piglets are provided with sufficient nutrition and enhance the resistance of piglets. During the gestation period of sows, the main purpose is to improve the survival rate of the fetus and the healthy growth and development of the fetus, so that the wide jujube piglets produced by the sow are healthy.

The main reasons for pre-farrowing feed reduction in sows:

1. Farrowing is a strong stress: if the sow does not reduce the feed before giving birth, the gastrointestinal tract will be temporarily disturbed after giving birth.

It will lead to the feed staying in the gastrointestinal tract of the sow for too long, which will eventually lead to constipation;

2. Constipation will cause low-grade fever in sows.

poor appetite; 3. If the sow's appetite cannot be quickly restored to a high level within 3-5 days after giving birth, it is bound to quietly affect the secretion of breast milk;

4. Poor breast milk secretion will inevitably affect the nutritional supply of piglets and lead to malnutrition in piglets.

Therefore, the main purpose of prenatal reduction is to quickly restore the sow's appetite after giving birth.

Look at the specific situation, it's not easy to analyze, I quickly disturbed a sow in the field for 7 days and didn't eat for 7 days, ruined and stuffy, and vomited. There wasn't much to do at the time. By the time of the birth, it was very normal, and the 13 piglets were very good. After giving birth, I ate the fiber bend.
