Why do not piglets grow


Sometimes it is difficult to figure out why the pigs do not grow, despite a full-fledged diet, good conditions of detention. Normally, pigs gain weight quickly. After six months of life, their weight is already about 100 kg. It happens that the process of growing young stock is accompanied by difficulties, and the growth of individuals slows down. The reasons for such deviations may be several. It is important to determine in time which of them adversely affects the development of specific pigs.

How to choose piglets for growing

A healthy baby pig is the key to successful pig breeding. Properly chosen animal will quickly pay back the corresponding investments. When buying babies should pay attention to external signs and behavior. For example, if a pig makes hoarse sounds when screeching, trying to dig into the straw, this may indicate a hidden pathology.

In addition, bite of the small pig directly affects the further growth and weight gain. The correct arrangement of the teeth allows the piglet from early childhood to grab and chew any food thoroughly. Otherwise, he will be able to suck only liquid food. This will negatively affect weight gain and growth. Normally, pig teeth should be on the same line.

Healthy piglets are different activity, mobility, good appetite. They have an even elongated body, a tucked up belly, smooth skin, uniform bristles, slender legs, and a dry, twisted tail. When buying several babies for cultivation, it is better to choose individuals from one litter. In this case, the competition for the feeder will be significantly lower.

The main causes of growth problems

Weight gain, animal development depends on their physiological state, living conditions, nutrition. In addition, pigs do not tolerate stress, so sometimes the pig does not grow because of anxiety, discomfort. To remedy the situation in each case, it is important to understand the nature of the deviations.

Inhibition of growth can be caused by the following main reasons:

  • anemia (anemia);
  • helminthic invasions;
  • lack of vitamins, minerals;
  • pellagra and other diseases;
  • poor feeding, unbalanced diet;
  • adverse conditions of detention.

What to do and why the pigs do not grow can be determined with the help of a specialist in veterinary medicine. Knowledge and understanding of the true causes of such deviations will help to take timely and adequate measures to accelerate the growth of animals.

Anemia in young pigs

During the first month of life, milk pigs are quadrupled in size. During this period, their exchange processes are activated. Muscles, tissues, internal organs of animals require a large amount of oxygen, which is carried by blood. Iron-containing protein of erythrocytes hemoglobin is responsible for this, therefore a growing body needs about 6 mg of iron per day. Sow milk does not cover such a need.

Already from the 5th day of life, milk pigs are required to give a special supplement, consisting of the most important trace elements. In addition, all pigs need to make injections at these periods of iron-containing drugs "Ferroglukin", "Ferraniimal", "Suiferrovit". Such a traditional procedure fills the shortage of substances necessary for intensive growth and development of pigs.

With "reduced" hemoglobin, small pigs suffer from shortness of breath, their skin turns pale, their immunity decreases, and diarrhea develops. Running cases can be fatal. Even in the absence of external symptoms, piglets grow very poorly, gain weight and develop.

Helminthic invasions

Infection of pigs with parasitic worms (worms) often leads to the fact that piglets do not grow. Worms live at the expense of their host, taking away most of the nutrients. This depletes the body, is the cause of its intoxication and loss of appetite in pigs. For example, ascaris larvae make breathing difficult and destroy blood cells. Such helminth infections can lead to anemia. Read more in the article "Ascariasis in pigs."

Infection of pigs with parasites can occur through contact with the earth, plants, and also through a sow. This occurs if in the final stages of pregnancy there was no obligatory deworming.

Analysis of pig stool piglets allows you to easily identify the eggs of worms. When confirming a worm infestation, an appropriate therapy should be carried out without delay. For this purpose, the preparations "Biomectin", "Nilverm", "Albentabs 360", sodium silicofluoride are suitable.

The same drugs are recommended for the prevention of helminthic invasions in piglets by deworming twice a year.

The dosage of the drug is calculated based on the weight of the animals. In parallel, you should make a thorough cleaning of the room with the use of chloride solutions. After cleaning the body of pigs, removing toxic products of parasites, the pig's appetite and its growth is significantly activated.

Avitaminosis, lack of important trace elements

Intensive growth and development of young pigs determines the diet rich in vitamins and minerals. The lack of the most important substances in the body leads to the fact that the pigs weaken, not gaining weight. In addition, the lack of specific vitamins causes certain pathologies.

For example, respiratory failure, dry pig skin, digestive disorders are obvious signs of lack of vitamins from group A. Sprouted grains, carrots, melons and gourds added to the daily diet can help fill them.

Directly on the growth rate of piglets, the functioning of their heart, vessels are influenced by substances of group B. Their lack leads to diarrhea and poor absorption of nutrients. Increasing the content in feed of legumes, yeast, bran, flax and fish meal, you can normalize the situation.

A deficiency of vitamin D immediately after the birth of piglets can lead to rickets, which is the cause of bone deformation. To compensate for the lack of this substance will help fish oil.

In addition, piglets need ultraviolet radiation, so they need to walk. In winter, it is necessary to equip the pigsty with a special lamp, due to which the light day increases. You should also diversify the diet of pigs with the help of cereals, roots, green herbs, complex supplements.


Exhausting diarrhea with mucus, constipation, edema in the mouth of the pigs characterizes a disease called pellagra. One of its signs is rough skin. The reason for this pathology may be a lack of B vitamins, proteins, tryptophan, nicotinamide. This often happens when the piglets are given little fresh grass, bran and vegetables, with an emphasis on boiled potatoes, grain feeds, corn.

This disease is accompanied by a reddish rash that appears on the body in places with the thinnest skin. Pustules spread throughout the body of piglets. Soon they burst and wet ulcers form in their place.

After some time, the area of ​​inflammation increases, and the ulcers merge together, turning into scabs. Pig skin is thickened all over the body, cracks and peeling appear. Against the background of such manifestations piggy significantly lose their appetite. Their development and growth noticeably slow down.

In advanced cases, pellagra is often fatal, so if you have signs of illness, you should immediately seek veterinary care. The whole therapy comes down to filling the piglets missing in the body. In addition to the necessary medication, it is required to enrich the daily diet with greens, meat and bone meal, milk, bran, and combined feed.

Proper feeding, full diet

A balanced diet consists of food containing all the necessary substances for the body of pigs. Their lack inhibits the full development of babies, badly affects the formation of lean muscle mass. Digestion and insufficient amount of drinking water worsens. Especially important to drink plenty of dry feeding.

For intensive growth, young pigs require protein. Grain mixes, dairy products, pea flour, cake, special combined feed, vitamin supplements, meal will help to create a balanced diet. In addition, it is important to monitor the taste component of the feed. To stimulate the appetite of pigs, you need to use salt, sugar, mustard, essential oils, lactic acid.

It is important to chop, boil potatoes and cereal components to feed small piglets. It is recommended to roast before grinding the grain. In no case can not give feed with mold, sour foods.

Vegetables and greens will also accelerate the development of piglets. After reaching a mass of 60 kg in the diet of young animals, it is necessary to introduce proteins of animal origin, since their absence can lead to slower growth. From this moment it is necessary to introduce meat and bone meal, reverse. To increase the appetite, it is better to feed animals fish waste.

On the effects of poor care and conditions

The environment significantly determines the growth and health of piglets. Comfortable temperature, low humidity, good light, cleanliness - the main signs of a good pigsty.

The minimum temperature inside the room where the piglets live should not fall below 18 degrees Celsius. With lower temperatures, most of the vital energy of animals will be spent on heating their own body. As a result, the growth of pigs will slow down significantly.

Air humidity above 70% provokes pulmonary diseases and weight loss. Badly ventilated area accumulates ammonia, hydrogen sulfide. In such an environment, piglets slowly gain weight. They lose their appetite, there are various diseases.

If even a healthy pig longer to hold in a cramped stale room with poor lighting in the company of other animals, they will not develop and grow. Even high-quality balanced feeding will not help. The stressful condition of the piglets makes all the efforts of the pig farms useless.
