What to do if a pig eats less or doesn t grow? What to do if the piglets don t like to eat

Personally, I think it is possible that the pig has a small appetite, so you can buy some appetizing medicine for the pig, so that the pig can become edible, and then it will naturally grow.

1) For pigs with other symptoms in addition to eating less or not eating, symptoms can be used, such as respiratory symptoms can be used in this program of antiviral powder with amoxicillin, because pigs do not eat when the immune function is low, the former is mainly to improve immune function of high-quality astragalus and other Chinese herbal extracts, the latter in the respiratory system of the blood concentration is the highest, so can receive the expected effect. If the body temperature of the sick pig rises, it can also be combined with the injection of some antipyretic drugs such as analgin**.

2) Check whether the feed is moldy and deteriorated, and replace the poor quality feed in time.

3) Improve the palatability of feed: such as adding some chili noodles can accelerate the intestinal peristalsis of pigs, adding an appropriate amount of salt or vinegar can also help pigs digest feed and increase pig feed intake.

4) Strengthen feeding management, reduce feeding density, feed to be fresh, nutrition to be comprehensive, feeding regularly and quantitatively, reasonable light, and keep the pig house clean and hygienic, good ventilation, pay attention to heat preservation and cold protection in winter, pay attention to heat stroke prevention in summer, and do a good job of vaccine immunization to reduce the occurrence of diseases.

What is the reason why piglets do not eat 1, gastroenteritis, diarrhea, etc. will cause indigestion in pigs and cause pigs not to eat. If you do not pay attention to the maintenance of the stomach and intestines during daily feeding, excessive feed will lead to the accumulation of feed in the stomach and intestines, causing gastroenteritis. When solving, the accumulation in the pig's stomach should first be expelled with drugs, and then fed some anti-inflammatory drugs and a small amount of dilute food.

2. Piglets not eating are often caused by diseases. Viral diseases and bacterial diseases can cause some infections and lesions or fever, and pigs are naturally reluctant to eat. At this time, it is necessary to prescribe the right medicine, and the pig will start to eat after the disease is cured.

3. The weather is too hot, the pigsty is not breathable, stuffy, and the food temperature is too high to cause the symptoms of fever and not eating, and in severe cases, it will lead to the death of pigs. When the body temperature of the pig rises significantly or the temperature changes greatly, the vent of the pigsty should be opened in time, and water can also be sprayed to cool down. 4. The moldy food is fed to the pigs, which finally causes the pigs to have gastrointestinal discomfort and loss of appetite; Feeding the same type of feed for a long time causes pigs to become anorexic and reluctant to eat again.

For the feed to be strictly controlled, the mildew feed should be removed in time, and the feed type needs to be replaced from time to time.

Weaned piglets have a 15-20% decrease in feed intake, growth stagnation, diarrhea rate of 30-100%, edema disease, disease resistance declines, affecting late growth, and serious zombie pigs.

2.Sow production and reproductive stress.

The initial weight of piglets is small, and the weaning weight at 25-28 days old is only kilograms, which seriously affects the growth in the later stage.

3.Didn't pass the replenishment level.

Piglets failed to feed in time during the lactation stage, could not eat well after weaning, piglets had severe dysentery, and the incidence rate of individual farms reached 60-80%, resulting in slow growth of piglets and stopped development. Therefore, piglets should generally start training and eating at the age of 7, and strive to be able to make up the feed at the age of 12 days.

4.Improper use of feed.

Compound feed from the mix to feed generally not more than 3 days, conditional pig farms should be fed on the same day, in order to ensure the freshness and palatability of the feed. If the storage time is too long, especially in rainy weather, the feed is easy to heat and deteriorate. In addition, some trace elements, vitamins, etc. are also easy to oxidize, thus affecting the feeding effect.

5.Poisoning with trace elements or heavy metals.

Modern pig producers mostly pursue the red skin of pigs, and blindly require high copper and high zinc to be added to the feed to achieve the sensory requirements of breeders and buyers, but they do not know that this is not only not beneficial to livestock products, but also seriously affects the growth rate of pigs.

6.In the early stage of growth and fattening pigs, high-dose antibiotics are used.

In the early stage of fattening pigs in the process of blind loss, producers in order to prevent disease, in the feed for a long time to talk about the addition of large doses of antibiotics, although this can improve the ability of animals to resist disease, but also lead to some bacteria to produce drug resistance, once these bacteria cause disease, it is quite difficult, often cause endogenous infection and double infection, so that the body's immunity decreases, disease resistance is reduced, resulting in the growth of fattening pigs in the later growth rate slowed down, the meat is relatively poor. In addition, it can also cause pig irritability, tail biting, ear biting, biting frame, and poor coat color.

7.Feed nutrient imbalance.

The human factor reduces the production cost of feed in the later stage, and the nutritional level is also reduced, resulting in the nutritional imbalance of pigs. For example, the energy and protein levels are insufficient, the crude fiber content is unreasonable, and in the actual production, a large amount of fiber feed is used in the later stage of growth and fattening, resulting in too much crude fiber in the feed, which affects the digestibility of other feeds, and also hinders the weight gain in the later stage of growth and fattening pigs.

8.Disease-led.

The main diseases that cause slow growth in pigs are: mild and recessive swine fever, pseudorabies, gastrointestinal diseases, respiratory diseases, etc.; For example, swine fever mainly invades the gastrointestinal tract of pigs, causing diarrhea in pigs, low absorption capacity of the gastrointestinal tract, and even no absorption of nutrients at all. In addition, parasites are the main factors that cause unexplained growth retardation in pigs, which are manifested as emaciation and slow growth, and the common ones are roundworm and scabies.

Why do pigs eat a lot but do not grow meat, there are two situations:

1.Porcine wasting disease.

Porcine wasting disease refers to some diseases of pigs, usually some infectious diseases, such as swine asthma and porcine circovirus disease. In the process of these diseases, the pig body consumes a lot of nutrients and energy in order to fight against the pathogenic microorganisms and the pathological damage caused by the pig body, resulting in the pigs not eating for a long time, and even getting thinner and thinner as they grow. Wasting diseases in pigs can be roughly divided into the following two types:

a.Swine asthma.

Porcine wheezing disease is a contact, chronic respiratory infectious disease of pigs caused by Mycoplasma pneumoniae (also known as mycoplasma) in pigs, the symptoms are cough, wheezing, body temperature, appetite has no change, and feed remuneration is reduced.

b.Porcine circovirus disease.

Circovirus type 2 can cause multisystem asthenic syndrome in weaned piglets, which is characterized by progressive wasting or growth retardation in piglets.

2.Zombie pigs. Zombie pig refers to a kind of pig that grows slowly, does not grow for a long time, and stagnates with growth and growth. The causes of the formation of stiff pigs are complex and affected by one or more factors.

First, the breeding environment 1The temperature is low, and the pig instinctively grows hair. 2.

The environment is uncomfortable, dirty, messy, etc. When people are troubled, the beard can grow up to 1 mm overnight. 3.

Circumferential leakage, environmental stress, etc., can also cause hair disorder. Such as noise, power outage, lack of water, etc. What to do:

Give the pig a warm and comfortable environment, a good mood, and the hair will not be so long. 2. Nutrition 1China's nutritional standards are low in energy design.

2.Low summer feed intake and insufficient daily feed intake (feed intake at formula energy levels). 3.

There are parasites, which is a wasting disease that consumes too much energy. Countermeasures:1

3.Attention should be paid to deworming. 3. Vitamin deficiency 1

The introduced varieties grow fast and are in high demand. 2.Feed intake is low in the summer heat and is required to relieve heat stress.

Countermeasures:1Pay attention to vitamin supplementation.

The safety and balance of minerals and trace elements, the raw materials of minerals and trace elements contain heavy metals that are toxic to the root group, which can affect the growth, metabolism and health of animals. In particular, the zinc-containing raw materials are accompanied by excessive cadmium elements, and when the cadmium content is high, it causes anemia and stunted growth. 2.

Zinc oxide for weaned piglets will cause hair growth, and high copper will cause hair bending. 3.Nutrient imbalance caused by minerals and trace elements (excess calcium, phosphorus, sodium, chlorine, sulfur, magnesium, copper, iron), pay attention to the balance between minerals and trace elements.

4.Hair length may be related to overall nutrition, vitamins, trace elements, energy, amino acids, etc., which are difficult to solve unless the formula is comprehensively adjusted.
