Pregnant gilts or sows can be fed:
- sow breeder pellets/nuts or
- milled barley / mixed with pig concentrate and
- a selection of vegetables (particularly cabbage and broccoli as they helps with milk production.)
What do you feed a pregnant sow or gilt?
Pregnant sows or gilts can be fed sow breeder pellets, milled barley and vegetables. It is important to increase the amount of feed given to the gilt or sow a few days before she farrows.
How do you feed a sow in a farm?
Feeding the Sow. During prefarrow in the facility, sows can be fed as they have been during gestation, that is limit fed 4-6lb./day depending on weather and housing conditions. Better results are often reported by producers, however, from feeding a laxative ration prefarrowing to preventing constipation.
How much to feed a pregnant sow?
Feeding Recommendations for Gestating Sows. The requirement at mating can be met with just 1.6 lbs. of feed, however to meet the requirement at the end of gestation 5.9 lbs. of feed is needed. To meet the requirement for both nutrients, it appears that 4 to 6 lbs. of feed would cover the range.
What do you feed a nursing pig during prefarrow?
This procedure will also eliminate ascaris (roundworm) eggs that would serve as a source of infection to the nursing pig. Feeding the Sow. During prefarrow in the facility, sows can be fed as they have been during gestation, that is limit fed 4-6lb./day depending on weather and housing conditions.
How much should a pregnant gilt eat?
It is recommended that gilts be fed 4.5–5.0lb/day for the 2-3 days around the time of mating. All other sows can be assigned a regular feeding schedule (Table 1). On the majority of farms there is no advantage of feeding other than a constant daily intake from day 3 to 100 of gestation.
Why is my pregnant sow not eating?
The 'common-sense' standard operating practice is not to feed during parturition. It is most likely that the sow will not eat at this time. They will also be less likely to eat during early labour, prior to the birth of the first pig. In the two to 24 hours before farrowing, most females are fed.
What do you feed a sow pig?
A corn-soybean meal diet containing 0.60 to 0.65% lysine will meet the requirements of most sows. Because threonine requirements are higher for maintenance than many other amino acids, L-threonine must be added with L-lysine HCl if synthetic lysine is used in the diet.
How much protein does a pregnant sow need?
These data suggest that a 260 g/day CP, 12 g/day lysine diet is adequate to support gestating gilt reproduction; however, increased protein levels (260 to 340 g/day CP, 12 to 16 g/day lysine) do increase gilt weight gain during gestation.
Do pregnant pigs need iron?
Adequate iron supplementation to the pregnant sows is expected to improve HbC in the sow and offspring and decrease the prevalence of stillborn piglets. Uptake of oral iron is not always consistent [16] and may be limited by e.g. antagonism among minerals [17].
How can I increase my pigs appetite?
Feed four to eight oz. per day per pig to help stimulate appetite. Water added to the feed also helps improve appetite and feed intake. The feed is softer and usually more palatable.
What is the best feed for pregnant pig?
One way to limit sow consumption during gestation is to feed a ration that is high in fiber content. We use soy hulls as a fiber source during gestation at the Purina Animal Nutrition Center. Additional fiber options include: beet pulp, rice bran, distiller's grains, wheat bran, wheat middlings and alfalfa.
What does a pregnant pig need?
During the pregnancy the sow will need plenty of feed high in nutrients and will especially need more feed towards the end of the pregnancy. She should be given some feed high in nutrients e.g. grain and greenstuffs every day.
Is salt good for pigs?
The right minerals are essential for muscle, nerve and immune system functions and for sound reproductive health. Salt is especially important for gestating and lactating sows, and can be useful as a carrier for other nutrients essential for swine.
What should a pig eat after giving birth?
colostrumAll newborn pigs should receive colostrum. Extra care for weak or small pigs and for large litters can result in more pigs weaned. In the first few days after farrowing, observe sows and pigs carefully for evidence of disease condition or inadequate milk production or intake.
How long does a pig stay pregnant?
Generally, the length of time a sow is pregnant, or gestating, is about 115 days, or 3 months, 3 weeks, and 3 days. During this time the piglets go through different phases of development, which we will separate into 5 major phases: Day 0-15, Day 13-30, Day 30-77, Day 77-90, Day 90-114.
Why should sows be flushed?
Providing an extra 2 lb./day for two weeks before breeding, commonly known as flushing, has been shown to increase litter size as much as one pig per litter. After breeding, feed intake for sows and gilts in good body condition should be reduced to 4 or 4.5 lb/day or the level they will be fed throughout gestation.
What causes loss of appetite in pigs?
Reduced milk production, loss of appetite and a higher body temperature are symptoms of mastitis in sows. It is caused by a bacterial infection of the mammary glands, where skin discoloration can be seen. Antibiotics, along with anti-inflammatory drugs are effective treatments.
Why is my pig not eating?
The most common reason why a pig won't eat is that it is dehydrated. Pigs need water to digest food. Eating while dehydrated will cause a pig to become even more dehydrated. As a result, pigs will stop eating as they get more dehydrated.
Is loss of appetite normal during pregnancy?
Is it normal to lose your appetite during pregnancy? Yes, it is normal to experience a loss of appetite or a change in food preferences during pregnancy, and these may play a part in how much your weight changes during pregnancy. Research shows that around 6 in 10 women experience a food aversion while pregnant.
Can not eating enough during pregnancy harm baby?
Undernutrition can lead to many pregnancy-related complications, including poor fetal growth, low birth weight, and maternal weight loss. It's also associated with lower mental function and behavioral problems in children ( 29 , 30 , 31 ).
What is the diet of a sow in the second period of gestation?
In the second period of gestation, the diet of sows includes concentrated feed (40%) and roughage, as well as juicy food (the remaining amount of the general norm). The second type includes:#N#+
What do pregnant pigs eat?
In the summer, the diet of pregnant pigs is enriched with various greens. Also at this time of year they can be fed with fresh beans, peas and lupins. They contain a lot of protein, which is necessary for pigs that are expecting offspring.#N#+
How much water do you need for a sow?
Low-sowing and deep-sowing sows weighing 120-150 kg experience a different need for water. For one head of low-pregnant uterus, 8-12 liters per day is required per day, for one deep-pregnant sow, 10-15 liters are needed.#N#+
What is the purpose of feeding gestating sows?
The objective of the feeding program for gestating sows is to achieve an appropriate, targeted sow weight gain during gestation that will allow optimum litter development and prepare the sow for lactation.
What is the purpose of breeding pigs?
The purpose of the breeding herd is to consistently produce a targeted number of high quality weaned pigs in an efficient manner and at low cost. Feed costs in the breeding herd constitute about 12% of the cost of producing a market hog. More importantly, the feeding program in the breeding herd can significantly influence sow productivity and longevity in the herd. Most costs, including feeding costs, in the breeding herd are fixed costs and therefore, increased breeding herd efficiency will reduce overall production costs. Therefore, there is considerable scope to reduce input costs and increase production efficiency through improvement in the feeding of the gestating and lactating sow.
Does backfat affect sow reproductive performance?
There is no convincing evidence that backfat thickness, by or of itself, has an influence on sow reproductive performance. In many studies and on most farms there are sows that perform well even though they have low levels of backfat. In a recent study at Kansas State University, sows with relatively low levels of backfat (0.49in.) at breeding had reproductive performance as good as sows with high levels of backfat (0.73in.; Young et al., 2004).Therefore, backfat by itself is not a reliable predictor of subsequent sow reproductive performance. It is likely that a thin sow that is gaining weight and putting on backfat will be more productive than a fatter sow that is losing weight or backfat. However, backfat level is a good indicator of the sow’s body reserves. The less backfat she has, the less reserves she has and so the margin for error in underfeeding the sow is very small. If a thin sow has to draw on body reserves during lactation to support milk production and has little backfat, she will mobilize her protein tissues as an energy source to meet her needs. It has been shown that if a sow mobilizes more than 12% of her protein stores during lactation, litter growth rate will be reduced and subsequent reproductive efficiency will be compromised (Clowes et al., 2003). Backfat can be measured electronically. These machines are durable, relatively inexpensive and are easy to use after some training.
How much feed is needed for a sow?
To meet the energy requirement of a sow at mating, 3.9 lbs. of feed is needed, whereas 5.3 lbs. is required for a sow at the end of gestation. If we do the calculation based on lysine, the average lysine requirement during gestation can be met with 3.6 to 4.0 lbs. of feed.
What is the best day to feed a baby pig?
The level of nutrition from day 21 to 50 may also be important to maximize the number of muscle fibers in piglets born. Primary muscle fibers set the stage for how fast and lean the baby pig can grow after birth and may therefore affect subsequent nursery and growing-finishing pig performance.
What is the proper nutritional management of gestating sows?
Proper nutritional management of gestating sows includes feeding the correct nutrient levels to meet the sow's requirement, but also correct management of feed amounts given to the sows at critical times in their development.
Can you feed a sow ad libitum?
Allowing sows to consume feed ad libitum between weaning and breeding may be a prudent practice, however, to help sows recover from weight loss during lactation and take advantage of a possible increase in ovulation rate and shorter weaning to breeding interval. Early Gestation.
How long is a sow pregnant?
The time period between breeding and farrowing is known as Pregnancy period. The duration of pregnancy is 114 day (3 months, 3 weeks and 3 days). 2.Feeding. 3.Health. Pregnant sows should be housed separately in special pens with sufficient floor space.
How long do sows feed?
Normal sow feeding regime can be maintained for the first 3 months of pregnancy. Following this, sows are placed in farrowing pens and fed ad libitum. Fetuses grow rapidly towards the end of pregnancy and nutrient requirements increase.
How long before and after a baby is fed bulky feed?
Feed highly with bulky feeds from 4-5 days before and after furrowing by substituting with wheat bran, ground legumes, which may help prevent constipation and reduce problems with mastitis- metritis- agalactia. Health: Pregnancy may be halted before term and the fetuses ejected: this is abortion.
Can pregnant sows be housed separately?
Pregnant sows should be housed separately in special pens with sufficient floor space. If space is available exercise is strongly recommended. Slippery floors may lead to falling causing accidental abortions. Feeding: Sows gain weight during pregnancy which consists of two-thirds body weight gain and fattening of the sow and for ...
Do sows gain weight during pregnancy?
Sows gain weight during pregnancy which consists of two-thirds body weight gain and fattening of the sow and for the embryos and embryonic fluid. Feeding is of particular importance and conversion of food into body weight is efficient and nutrient retention is very high.
Can swine fever cause abortion?
Vaccination against swine fever during the first month of pregnancy may provoke viral infection of the placenta resulting in abortion. If there are a number of consecutive abortions notifying a Veterinary Surgeon is recommended to identify the cause and suggest appropriate remedies.
Can sows eat fetuses?
It must be understood that sows may eat both fetuses and placental membranes and that some abortions may not be recorded by the farmer. Important diseases including swine fever and salmonellosis, may cause abortion although these are not the only possible causes. Mouldy feed may be responsible.
What is the purpose of care for pigs during gestation?
Proper care of the sow during gestation, farrowing, and lactation is a means to reach a goal — a large litter of healthy pigs at birth that will remain healthy and grow rapidly. Care during this time must also prepare the sow for a successful repeat performance at the earliest time within the system of weaning and rebreeding used.
How to know when a sow will farrow?
Knowing When a Sow Will Farrow. The sow must be at the right place at the right time for farrowing, according to the management system used. Recorded breeding dates, calculated farrowing dates, and close observation are essential for proper farrowing management.
How does farrowing affect pigs?
The Birth Process. Attending sows at farrowing decreases the number of “stillborn” pigs that die during birth or within the first few hours afterwards; pigs can be freed from membranes, weak pigs revived, and care can be given that reduces other deaths in the first few days after farrowing.
What happens if a sow is nervous?
Sows may become restless or nervous, may try to escape the crate, chew on anything available, urinate frequently, and attempt to build a nest or bed. If milk is present, the sow should be prepared and moved immediately to the farrowing facility.
How to clean a nursing pig's belly?
Washing the Sow. Before the sow is placed in the farrowing pen, wash the teats and belly with mild soap and warm water. This will eliminate soil and fecal material that may contain numerous bacteria that are potential diarrhea-producing agents for the nursing pigs.
When should a sow be in a crate?
If farrowing is to take place in a crate or pen, the sow should be in that place no later than the 110th day of gestation.
What temperature should a baby pig be?
On solid or slotted floors without bedding, baby pig areas should be kept at 90-95°F for the first few days, and then in the 70-80° F range until weaning at 3-6 weeks of age.
Introduction
Objectives
- The objective of the feeding program for gestating sows is to achieve an appropriate, targeted sow weight gain during gestation that will allow optimum litter development and prepare the sow for lactation.
Feeding For Lifetime Productivity
- All phases of the reproductive cycle are interrelated. Therefore, the feeding and management of the gestating sow can influence feed intake and sow performance during subsequent phases of her life. High feeding levels in gestation that result in backfat levels at time of farrowing of 0.83in. or more will reduce feed intake during lactation, especially in early lactation of most genotypes (…
Guides to Determining Feeding Allowances
- During gestation the pregnant sow requires nutrients and energy to maintain her bodily functions, for weight gain and to supply the developing litter (NRC 1998). Maintenance represents 75-85% of the total energy requirement of the pregnant sow (Noblet et al., 1990). Maternal weight gain represents approximately 15-25% of the energy requirement of the sow. The composition of the …
Estimating Sow Feed Allowance
- In many herds condition scoring is used to determine the feeding level of the pregnant sow. It is assumed that condition score reflects the level of fatness of the sow. Usually sows are assigned a condition score of 1-5 based on visual assessment and palpation of the sows back at the position of the hip bones. A score of 1 is given to very thin sows and a 5 would be a very fat sow…
Backfat Measurement

In many studies and on most farms there are sows that perform well even though they have low levels of backfat. In a recent study at Kansas State University, sows with relatively low levels of backfat (0.49in.) at breeding had reproductive performance as good …
Measuring Backfat
- Suggested target backfat levels for sows might be : Backfat level, in.* At breeding 0.60-0.65 At farrowing 0.75-0.80 At weaning 0.60-0.65 1. backfat measured at the last rib, 2.5-3.0in. off the midline of the sows back (Figure 2). It is important to note that the target backfat levels are not average herd values but are targets to be reached by every sow. A target of 0.7-0.8 in backfat at …
Suggested Feeding Allowances For Gestating Sows
- Using data from published reviews (NRC 1998; Young et al., 2004b). A spreadsheet can be developed to determine the daily feeding levels for each sow based on her weight and backfat level at breeding. These feeding allowances also take into account the sow weight gain needed to attain the targeted increase in backfat required for each sow. The maintenance requirement is t…
Pattern of Feeding
- It is recommended that gilts be fed 4.5–5.0lb/day for the 2-3 days around the time of mating. All other sows can be assigned a regular feeding schedule (Table 1). On the majority of farms there is no advantage of feeding other than a constant daily intake from day 3 to 100 of gestation.
