How old is a weaned pig

Weight dispersion affects hierarchy —and therefore competition between piglets for resources like feed, water, place in the pen, etc. Age variability affects "maturation" of the piglet's digestive tract, the amount of creep feed ingested and therefore adaptation to solid feed.

Usual working procedures involve classification of piglets by size, aiming to minimize the negative impact of weight dispersion. Therefore, on arrival of a batch of weaned piglets, they are classified in various sizes: large, small, medium. Feed presentation and management: additional feeding pans, wet feed, increased feed supply, etc. Photo 2. Photo 2 The use of gruel or semi-moist feed favours early days feed intake and adaptation to solid feed.

I recommend not to use piglet size as the only variable, and to identify piglets in groups 2 and 3 when receiving piglets in a nursery. Table 2: If groups g 2 and 3 are not differentiated, these piglets will not be managed differently from those of the same size but different age. Table 3: Once we differentiate piglets in groups g 2 and 3 from those in group 1, they can start receiving a specific, age-appropriate treatment. Fostered piglets, especially, can receive gruel and a little more pre-starter than if they were classified just as "large" piglets.

Hyper-prolificity allows to wean more piglets per sow, but requires a more demanding management in the nursery, and increases weight and age dispersion at weaning due to the use of foster mothers. Differentiating younger fostered piglets and repeaters allows proper management of these piglets, reducing the number of poor doing piglets and improving their performance.

Use either a surgical knife or side cutter to castrate. The surgical knife can be either a 12 hooked blade or straight blade. The instrument of choice must be sharp and disinfected. If the scrotum is dirty, clean it and surrounding area with a cotton swab soaked in a mild disinfectant.

Hold the piglet by both hind legs with its head down. Push up on both testicles and make an incision through the skin toward the tail Figure Be sure to cut low in the scrotal sac to ensure good drainage. It does not matter if you cut through the white membrane or not. Pop the testicles through the incision and pull on them slightly.

Pull each testicle out pressing your thumb against the pelvis of the piglet. Otherwise, you may cause a hernia. Also, cut any cord or tissue protruding from the incision and spray the wound with an antiseptic. This technique is best performed on piglets between four and 10 days of age. There is little or no bleeding with this method. Hold the piglet between your legs with the belly outward. Use your index finger, or whichever is comfortable to use, to push up on one testicle to make it more pronounced.

The resulting fold of skin is where the incision is made Figure 11a. Position disinfected side cutters about two thirds of the way into the fold and make a cut directly through the scrotal tissue right of the midline.

Make a similar incision through the scrotal tissue, but to the left of the midline. Pop the testicles out through the incisions by pinching your thumb and index finger together Figure 11b. Press very firmly with your index finger against the pelvis of the piglet in front of the scrotum and pull the testicles out with the side cutters Figure 11c.

Care is taken to avoid cutting through the cords beneath the testicle. Remove any loose cord tissue left outside the incision. Nothing but the disinfected side cutters touches the exposed tissue. Spray the wound with an antiseptic. One person holds the piglet by the rear legs while another does the castrating. With one hand, tighten the skin over the scrotum to help expose the testicle and the site for the incision.

With the castration knife, make two incisions about as long as the testicles near the center of each Figure 12a. Cut deeply enough to go through the outside body skin. It does not matter whether you cut through the white membrane tunica vaginalis , which surrounds the testicle, or not.

Squeeze, or pop, the testicles through the incision Figure 12b. Enlarge the incision slightly at the end closest to the tail if the testicle will not pop out. Pull out the end of the testicle which is toward the tail at a right angle to the length of the body and cut the cord close to the incision Figure 12c.

Do not pull straight up on the testicle. Repeat the procedure for the second testicle. Observe castrated animals for excess bleeding or the presence of tissue or intestines hernia. Apply pressure to the wound for about two minutes to stop any bleeding. Cut off any cord that may be protruding from the incision as this may serve as a wick for infection, but make sure it is not intestine. If intestines protrude and they are black or torn, it is usually best to euthanize the piglet.

If the problem was recognized promptly after the intestines came out, it is possible to save the piglet. Close up by suturing the tunica vaginalis white membrane which surrounds the testicle. If a skilled professional is not available to suture the tunica vaginalis, simply suture the castration incision closed to allow time for a skilled surgeon to repair the hernia properly a few hours later.

If a skilled surgeon is not available in a few hours, the piglet should be euthanized. It is much easier to replace the intestines if the tunica vaginalis covering the testicle is not removed during castration. Administer an antibiotic after surgery. Proper equipment care will help ensure that piglets will be processed with minimal discomfort and complications from infection.

After each use, place equipment such as side cutters and ear notchers in a bowl of nonirritating disinfectant. Do this rather than laying equipment on the cart or platform after they have been used to process each piglet. Change the disinfectant after about every ten litters. Before moving to another farrowing room to process, clean and disinfect the cart and equipment. Also, check needles to ensure they are not bent or blunt on the end.

Replace needles after they have been used on piglets or earlier if damaged. Dispose of needles in a sharps container. Pork producers who use birth weights as part of their management system can incorporate the weighing into the piglet processing routine.

Most piglets are not weighed at birth, but if they are, this should be done first, followed by the rest of the processing. Some producers weigh each piglet and record the sex and weight. Others place the entire litter on the scales and record total litter weight. We recommend pork producers use production records to identify strengths and weaknesses in the operation.

If problems are experienced in the farrowing quarters, these problems will continue to propagate if accurate records are not kept. It is important to realize that reproductive traits are heritable. Record keeping allows superior sows to be identified and retained on the farm. This will lead to successive improvements in lactational performance which should lead to fewer problems in the farrowing quarters.

Records help management identify people who are doing a good job which may be rewarded and they help identify weak areas that the caretaker can work to improve. Records kept in the farrowing quarters include: birth date, number of piglets born alive and dead, date and cause of death of piglets, pedigree information, number of piglets weaned, and piglet or litter weaning weight. Remarks on anything unusual or wrong with the piglet should be noted as well.

In addition, many producers are recording feed intake during lactation. Medications given to animals should be recorded to ensure treatment protocols and withdrawal periods are followed. Have cards, clipboards, or other recording devices near each farrowing crate or pen. Having the opportunity to record information the moment it is collected or observed ensures accuracy.

Always have a pencil or pen in your pocket and also with the equipment used to process piglets. Record data in ink whenever possible and practical. This makes the forms easier to read and ink also withstands the environment of the farrowing quarters better. Also, record data in legible handwriting and make it a habit to write your initials beside the entry if more than one person routinely works in the farrowing quarters.

Closely observe each piglet at least twice daily for evidence of adequate milk production by the sow. Careful observation of piglet behavior and body condition is the best method of determining if a sow is milking well. Lactation failure must be treated aggressively and the litter may need to be given supplemental milk as the sow is recovering.

Healthy, well-nourished piglets run around and play, especially when the sow rises to eat. For the first few days of their lives, piglets do little more than eat and sleep. However, in a few days they begin to be active away from the udder. These activities are delayed in piglets that are sick or undernourished. After a successful nursing, piglets will often settle down and sleep. Milk is frequently seen around their mouths. In the normal sow, milk ejection from the teats starts about one to three minutes following initiation of nursing behavior which occurs about once each hour in early lactation.

Then oxytocin is released and milk letdown occurs. The piglets will nurse steadily for about 30 seconds then gradually quit.

Piglets nursing a sow with lactation failure will spend more time at the udder, including fighting, and will be less content. Well-nourished piglets have tight, shiny skin and a thrifty look, i. Much of that fat is stored just under the skin. It is that rapid accumulation of subcutaneous fat that gives piglets tight, shiny skin and a thrifty look. Preventing piglets from encountering disease agents primary prevention involves five basic areas: 1 source and handling of primary and replacement breeding stock, 2 rules governing movement of people, vehicles, materials, and pigs, 3 layout of the farm, 4 location of a new farm, and 5 cleaning the farrowing quarters and the sow.

We recommend producers divert more resources to primary and secondary prevention techniques. Less emphasis should be placed on the less effective and more costly approach of using drugs and biologics to treat sick piglets. How much to divert and the response to expect will depend on the current status of the herd.

A record program that can store the necessary information and allow data retrieval in a usable format is the basis of an effective health program. The most important aspects of maintaining the health of piglets is to ensure they receive as much colostrum as possible and that they have a warm, draft-free environment.

Regardless, piglets will die of disease and the causes can be broadly classified as those occurring regularly endemic or only occasionally epidemic.

Colibacillosis and Coccidiosis are often endemic diseases. Determining the cause of neonatal pig losses is not easy because few diseases produce signs that are unique to the causative agent. For example, baby pig scours can be caused by a bacteria, virus, or parasite and you cannot distinguish between them by the nature of the scours.

Your veterinarian can assist you in obtaining a diagnosis and recommending treatment. For the experienced observer, some diseases which occur regularly on the farm can be recognized by farm managers and treatment instituted as soon as the signs are recognized.

However, if the piglets do not respond to treatment, then contact your veterinarian to reassess the situation and check the diagnosis.

Appropriate treatment will vary depending on the cause of the disease. Provided the organisms are sensitive, antibiotics will usually alleviate a bacterial infection; however, antibiotics will not affect viruses or parasites. Sometimes antibiotics are recommended to help prevent secondary infection when the primary infection is a virus or parasite. In these cases, the antibiotics do not affect the organism causing the disease, they just help ensure that bacteria do not take advantage of the weakened piglet.

Treatments for individual diseases are discussed below. Remember that all drugs must be administered according to label directions unless your veterinarian has directed you to do otherwise. Clostridial Infections. The disease is caused when Clostridium perfringens, which is a normal inhabitant in the large intestine, becomes established in the small intestine.

This usually occurs when the piglet has had insufficient intake of colostrum. Its severity will vary dependent on the type, A, B, or C the most severe , but piglets usually develop a foul smelling diarrhea and many will die. It is more commonly seen in piglets less than seven days old. Antitoxins can be injected into sows and piglets and oral ampicillin is commonly recommended.

Congenital Tremor. Most pork producers have seen newborn pigs with tremors and shaking muscles. It is also associated with hereditary disease in Landrace and Saddleback breeds or with organophosphate poisoning. Affected piglets must be assisted to suckle and provided for until they grow out of the disease in a few weeks.

Greasy Pig Disease. Exudative Dermatitis. Greasy pig disease is often a problem in newly established gilt herds. The causative bacterium, Staphylococcus hyicus, infects the skin of a piglet and produces a toxin that damages its liver and kidneys. A piglet is usually infected at, or soon after, birth. The first clinical signs appear between 4 to 35 days when small dark spots appear on the side of the face.

Then, brown scales develop on the underside of the piglet which, in serious cases, spread to cover the whole piglet. Severely affected piglets usually die and survivors do poorly. Affected herds can suffer decreased growth performance for 12 months. The disease is readily recognized by its typical appearance, and treatment is most successful when started as soon as signs appear. Before antibiotic treatment is started, affected live piglets should be submitted to a laboratory to determine the antibiotic sensitivity of Staphylococcus hyicus Greasy pig disease is difficult to control unless mange is first eliminated.

The mange mites damage the skin and allow Staphylococcus hyicus to enter. Affected piglets should be given electrolytes orally because they become dehydrated rapidly. Some farms experiencing severe outbreaks have had success using an autogenous vaccine.

Epe is a difficult disease to both understand and treat. The causative rickettsial organism, Eperythrozoon suis, is present in the blood of sows in both healthy and diseased herds. In some piglets, it attaches itself to red blood cells and destroys them causing anemia. Affected piglets are weak, pale, and jaundiced, have scours and pneumonia, and suffer high mortality.

Before attempting to treat for Epe, it is very important to have your veterinarian confirm the diagnosis. The response to drug treatment is poor and, at the time of writing, the Food and Drug Administration FDA has not approved any drug for treating Epe. Eperythrozoon suis is spread by infected blood so, when attempting to control an epidemic, it is very important to clean and disinfect instruments between piglets when processing.

Anything that can result in blood being transferred between piglets must be controlled including parasites, fighting, tagging, and injections. The disease usually affects weaned pigs, but suckling piglets can be affected.

Often the heaviest, best looking, piglets die. Pigs are fevered, depressed, slow to rise, lack appetite, and have swollen joints. Some have nervous signs such as tremors. Before they die, the skin often turns blue and the eyes are reddened.

The organism is hard to grow so diagnosis is usually made solely on clinical signs and postmortem findings. Hemophilus parasuis is sensitive to a wide range of antibiotics including the penicillins, tetracyclines, and ceftiofur.

It is best to start treatment as early as possible and a combination of injectable and water medication is usually indicated. In problem herds, autogenous vaccines can be useful. PRRS is usually only seen in unweaned piglets when the disease first infects a naive herd. Piglets may cough, sneeze, and have diarrhea, conjunctivitis, and difficulty breathing.

Signs in individual herds will vary because of the effects of different secondary infections. Individual piglets should be rehydrated and treated with antibiotics to control secondary infections. A herd control program should be formulated in conjunction with the attending veterinarian. Tetanus is rare in piglets but sometimes the causative bacterium, Clostridium tetani, will infect piglets when they are castrated.

Because the incubation period is weeks, signs are rarely seen until the pigs are at least two weeks old. Affected piglets are stiff, have an erect tail, and facial muscle spasms. For problem herds, an effective vaccine is available. Managers should review castration and other processing procedures to ensure they are using hygienic techniques.

The diseases mentioned above are the main ones found in suckling piglets. Other diseases may rarely occur—when they do, it is usually associated with overwhelming infection in a naive herd. Euthanizing animals is an unpleasant but necessary part of livestock farming. Producers often have to euthanize piglets because they are sick and suffering with little-or-no chance of recovery. Some piglets should be euthanized because if left to live they become a source of infection for their pen or littermates.

In these and other similar situations, euthanasia is the humane and responsible solution. Piglets should be euthanized by exposure to carbon dioxide or blunt mechanical trauma to the head. Electrocution is acceptable but it can be a human health safety hazard, and piglets must be processed one at a time making it very time consuming.
