What Are The Consequences of Phosphorus Deficiency?

Phosphorus is one of the essential mineral elements of animals and plays an important role in animal growth, development and production. Phosphorus feed additives are also the third most expensive feed ingredient in addition to energy and protein. Even if it is so expensive, livestock farmers will not stop using this feed additive because the consequences of phosphorus deficiency in animals are very serious. This article will explain in detail the consequences of the lack of phosphorus feed additives.

The main points are as follows:

• The use of phosphorus

• Phosphorus deficiency

• Treatment

 

The use of phosphorus feed

Phosphorus is second only to calcium in animals. It is an important component of animal bones and teeth. It is also an important component of genetic material and most enzymes. Its biological function is the most among mineral elements, including:

1) Participate in the formation of bones and teeth.

2) constitutes ATP and creatine phosphate, which participate in the body's energy metabolism.

3) Promote the absorption of lipids and fat-soluble vitamins by phospholipids and ensure the integrity of biofilm.

4) It is an important component of genetic material such as DNA and RNA and participates in most of the enzymes.

5) Composition Na2HPO4/Na2H2PO4 buffer pair to adjust the acid-base balance.

 

Phosphorus deficiency

1. Chicken

1.1 Chicken rickets

Rickets often occur in chicks under 6 weeks of age and vary in performance due to lack of nutrients. The sick chickens showed leg squats, unstable walking, slower growth, softer and more elastic bones and enlarged joints. The ankle joint is especially noticeable. Sick chickens often take a squat posture when they are resting. When the disease develops seriously, the sick chicken can be paralyzed. However, when phosphorus feed is deficient, it usually does not show symptoms of spasticity.

1.2 Cage laying hens

At the beginning of the disease, the chickens are healthy and have normal spirits. They can eat, drink and lay eggs. After the emergence of soft shell eggs and thin shell eggs, the egg production is significantly reduced, the legs are soft, standing difficult, if you can find it in time, take timely measures, can quickly recover. Otherwise, the symptoms gradually become more serious, and finally, the side is lying in the cage. At this time, the reaction of the sick chicken was slow, and finally died due to the inability to consume and drink water and extremely extreme weight loss.

 

2. Pig

Pigs are one of the most prone to calcium and phosphorus feed deficiency, and pigs at different stages have different calcium and phosphorus requirements. Porcine calcium phosphate deficiency is caused by a deficiency of calcium and phosphorus in the feed or a mismatch between the two. Young pigs show rickets, and adult pigs develop bone soft disease.

Congenital rickets often manifest as enlarged bones in the face of the piglets after birth, hard sputum prominent, swollen limbs, and can not flex, the pigs are weak and weak. Acquired rickets have a slow onset, early loss of appetite, indigestion, lack of energy, reluctance to stand and exercise, and heterosexual embarrassment; with the development of the disease, the joints are swollen and hypertrophic, palpation pain sensitive, limp, bone deformation;

Piglets often stand with wrists or crawl with wrists, hind limbs with ankle joints; late in the disease, bone deformation is aggravated, concave back, "X" shaped legs, facial bone bulging, difficulty in feeding and chewing, ribs combined with costal cartilage The area is swollen and the pressure is painful.

Osteoporosis in adult pigs is more common in sows, and the initial manifestations are digestive disorders dominated by heterosexuality. Then there were movement disorders, stiff waist and legs, standing on the back of the arch, strong movements, lameness, and often lying or not. In the later stage, the joints, wrists, ankle joints become enlarged and thickened, the tail vertebrae are softened, and the ribs and costal cartilage are beaded. The head is swollen, the bone ends are thick, and the fracture and tendon attachment are prone to occur. Avulsion.

 

Treatment

• Chicken rickets treatment

If the diet is deficient in calcium, it should be supplemented with shell powder and stone powder. When the phosphorus feed is deficient, calcium hydrogen phosphate should be added. The imbalance of calcium and phosphorus should be adjusted.

• Cage laying hens

Pay attention to the supply of calcium and phosphorus in the feed, the proportion of phosphorus feed and calcium, and the supply of vitamin D. The sick chickens are found in time, and the individual breeding is carried out to reduce losses.

• Porcine rickets

Treatment to improve the feeding management of pregnant sows, lactating sows and piglets, supplement the feed of calcium, phosphorus and vitamin D, such as green feed, bone meal, eggshell powder, clam shell powder, etc., to rationally adjust the calcium and phosphorus in the diet feed. Content and proportion, while properly exercising and illuminating daylight.

For the diseased piglets, Vitreic calcium injection can be used, 0.2% mg/kg body weight, intramuscular injection once every other day; vitamin A, vitamin D injection 2-3 ml intramuscular injection, once every other day.

Adult pigs can be intravenously injected with 10% calcium gluconate 50-100 ml once a day for 3 days. It can also be combined with sodium selenite to improve the curative effect. In addition, 20% sodium dihydrogen phosphate injection 30-50 ml ear vein injection once, or fed bran (1.5-2 kg bran plus 50-70 g yeast powder after cooking, daily feeding) . It can also be used with 2-5 grams of calcium phosphate and fed twice a day.

 

The above is the consequence and treatment of the lack of phosphorus feed additives. It is easy to see that phosphorus feed cannot be lacked in any way. The consequences of phosphorus deficiency are unbearable, which means that we lose all livestock production results. Only by learning to use phosphorus feed additives can our livestock products grow healthily and bring us benefits.
