If a pig does not eat and stops growing, any animal breeder will get worried. The reason for the lack of appetite in animals can be anything from illness to bad weather. Sometimes this is a temporary phenomenon that can be easily eliminated, and sometimes the cause of malnutrition has to be fought for a long time and thoroughly. In any case, ignore the problem, hoping that it will disappear itself, not worth it. About why pigs and piglets stop eating, and what to do about it, read below.
Why do animals lose their appetite?
When a pig refuses to eat, the reasons can be very different. We consider the most common:
- parasite infection;
- lack of vitamins;
- infectious diseases;
- improper diet;
- physical abnormalities;
- poor conditions in the pigsty.
Normally, piglets gain weight very quickly. For six months, pigs can "get better" at 100 kg. If you notice that the animal has become little to eat, you need to contact the vet. Often, only he can correctly diagnose.
However, it is not always possible to invite a good specialist, and you have to act independently. To understand what is wrong with the pigs in your farm, analyze whether they eat a full meal, live comfortably, given their age. Examine the animal - some diseases "present themselves" with characteristic external signs. Sex is also important, as some diseases manifest themselves differently in males and females.
Signs of worm infestation in animals
Helminth infestation is the most common reason why piglets do not grow or eat. It is possible to suspect helminthiasis if the animal has characteristic signs.
First, the pig eats badly and quickly loses weight. For a couple of weeks or even less, an animal can lose so much weight that the ribs begin to stand out. Another sign is coughing. There may be restless behavior, fever. Piglets often vomit. Not always, but usually in the excrement you can see worms.
Adult animals and young animals become infected, rummaging through the manure, the earth, using dirty food. Sows can pass helminth eggs to piglets if they were not grafted on time. In this case, the infection occurs during feeding.
Also plays a role in compliance with sanitary standards on the farm, especially when the content of sows with offspring.
Treatment for worms: medicines and folk methods
Treatment of parasites today is not a problem. From drugs for helminthiasis, sodium fluorosilicate can be used in powder form. It is mixed with food and give two days. Pigs that weigh from 40 kg are fed up to 4.2 g of powder per day. If a pig weighs less, for example, 30 kg, the dosage will be 2 g. For suckling babies, this treatment is not suitable, but gender does not matter.
There are also special pills: biomectin, brovermectin, albentabs-360, kelamectin. Their use must be coordinated with the veterinarian. If the animal burps, or the medicine cannot be given inside for another reason, you can prick ivermek. The dosage of all these drugs is calculated by weight of the pig.
Use nilverm powder of 0.007 g per kilogram of piglet weight twice a day. The course is two days.
From folk remedies, ordinary garlic has proven itself well. It is added to food or given by force, mixed with other food, at the rate of 1 g of garlic per 1 kg of weight. Tansy flowers can also be given to animals. For a pig weighing 30 kg, enough teaspoon. More well-fed individuals give a tablespoon of crushed flowers. This therapy continues for two weeks.
Needed and general cleaning in the room. Floors must be cleaned with bleach.
Vitamin deficiencies: signs and problem solving
If the pig is not eating, a simple addition of vitamins to the diet can be a treatment. Lack of certain substances disrupts the body and causes loss of appetite.
As a rule, when a pig does not grow, it lacks vitamin D. This is especially common in animals that are few in the sun. In this case, injections of drugs will help prodovit, eliovit or tetrahydrovit, plus the nucleopeptide. They stimulate growth. Injections are made once a week. If you do not want to give an injection, add fish oil to the pig feed, regularly switch on the UV lamp indoors.
Lack of iron can cause anemia in pigs, and because of her appetite is deteriorating. A piglet develops more slowly, sometimes it reaches the death of an animal. Anemia occurs in suckling babies, since milk contains less iron than is needed. For prophylaxis, 5-8 days after the birth of the young, iron preparations are introduced: ferroglucin, ferranimal, suifaravit.
Lack of vitamins A and group B has the following symptoms: dryness and flaking of the skin, problems with the heart and breathing, digestive disorders. You can enter into the diet of pigs germinated grain, carrots, pumpkin, grass. In severe cases, the veterinarian prescribes a pig injection of vitamins.
Influence of conditions on the development of animals
Pig breeding involves comfortable conditions for animals, especially for a growing organism. Otherwise, do not fatten the pigs. If it is too hot or cold in a pigsty, it affects their health and development. Fortunately, gaps in the content can also be corrected.
If you keep indoors piglets recently taken from a sow, the temperature there should not fall below +22 degrees Celsius. Fattening animals feel good at a lower temperature - up to +14 degrees. The sex of the young here does not matter either - the temperature is the same for everyone.
When it is colder indoors, the body spends its strength to keep warm, all processes slow down. In the heat of over +30 degrees pigs are also uncomfortable. They stop eating and very slowly gain weight.
It is extremely important what the floors in the pigsty, the microclimate largely depends on them. They should be dry, clean, with a hygienic bedding, not slippery.
Physical impairments that prevent normal growth
Before you think about why pigs eat badly, it is worth remembering whether you were careful when buying or inspecting them after birth. Sometimes physical or genetic abnormalities are to blame.
So, poor appetite may be due to improper bite. It is difficult for a piglet to chew food normally, so it eats little, and food is less digestible. Seeing this deviation is easy. You need to take the animal, push his lips and carefully examine his jaw.
All teeth should be level. If the jaws are five, eight mm or more in relation to each other, this is a flaw. Such a pig will not normally eat and develop.
When you buy pigs, take brothers and sisters, they will not conflict. Stress and fights with relatives also have a bad effect on the development of animals. However, check if the parents were not close relatives of the piglets. If there were, litter will be weak. Toddlers will often be ill, and weight gain slowly. May not be viable at all.
Wrong balance of proteins, fats and carbohydrates
Proper diet in the first 6 months of life is extremely important pig. This is the period of the most intensive development. But in the future the pig should receive a balanced diet.
If you fed a lot of piglets, they ate, but gained little weight, perhaps they lack protein; it should be not only vegetable, but also animal.
This is especially important in the first half of the year, when piglets build muscle (from about 7 months more fat grows).
Knowing what to do, you can easily solve the problem. To animals get enough protein, enter in their food lysine (acid, included in proteins), protein supplements. In winter, it is good to give yeast to pigs. By the way, the floor also practically does not affect the need for proteins.
You can make a mixture of oilcake, pea flour, cereals and vitamin-mineral supplements. It will provide the normal balance of most substances in the body of animals.
By the way, if a pig does not eat well, pay attention to the color of the feed. There are studies showing that pigs prefer light colored foods.
The main diseases that prevent fattening animals
When not eating a pig, you should always suspect the disease. Many diseases cause loss of appetite, lead to stunted growth and development. Consider the most common.
Against an unbalanced diet, animals can develop pellagra. Besides the fact that piglets do not grow, this disease is terrible consequences, namely - the death of young. Symptoms of pathology: rash, turning into ulcers, peeling and cracks in the skin, inflamed gums, dull bristles, digestive disorders.
When transferring suckling pigs to a different diet, they sometimes have dyspepsia or gastroenteritis. The symptoms of these ailments are diarrhea and vomiting, low body temperature, refusal to eat.
All sorts of respiratory diseases can also explain why the pig does not want to eat. For such ailments, coughing, conjunctivitis, nasal discharge, weakness, fever are the characters. In this regard, read the article "Body temperature in a pig."
Other diseases and how to recognize them
If you do not vaccinate in time, the pig can become ill with erysipelas. This disease has a bacterial nature, usually occurs in summer or late spring. Causes - special microorganisms that live in the soil, and non-compliance with hygienic standards.
In the face, the pig not only loses its appetite, but also drinks a lot. The temperature rises, a rash appears on the skin. The animal weakens, lies a lot.
Pigs from two months to six months may become infected with paratyphoid fever, if the sow is poorly fed, and the housing conditions left much to be desired. Piglets have alternating diarrhea and constipation, weakness. All this is accompanied by a reluctance to eat and high body temperature.
We have listed the main causes of poor appetite and stunting in piglets. It is worth remembering that some of these diseases can mow half of the livestock, and poor nutrition affects the weak individuals, but harms everyone, regardless of age, gender or pedigree. Therefore, if at least one piglet began to disturb you, immediately call the veterinarian.
