Several misunderstandings of vitamin supplementation in broilers

(Summary description) Farmers only choose the multivitamin series when adding vitamins. Broilers grow faster and require more vitamins. When supplementing vitamins, the physiological needs of broilers of different ages and needs in different environments should be fully considered.

Information

Misunderstanding 1: There is a single variety of vitamins

Farmers only choose the multivitamin series when adding vitamins. Broilers grow faster and require more vitamins. When supplementing vitamins, the physiological needs of broilers of different ages and needs in different environments should be fully considered. For example, chicks from the start of feeding to one week of age are timid and weak in resistance. Any slight change in the external environment may cause it to produce a stress response, and it is also extremely vulnerable to the invasion of various harmful organisms from the outside world and infection of diseases. So adding Vc in the early stage of brooding is extremely beneficial for chicks. Chicks grow and develop rapidly during the period of 2 weeks to 6 weeks old, and their metabolism is vigorous, which requires a large amount of enzymes to participate. Therefore, the requirement of B vitamins, which are an important part of enzymes, should be increased at the same time. At this time, it is necessary to supplement some B vitamins according to the actual situation. When the flock is sick, adding vitamins as an adjunct to treatment plays a very important role, especially adding VA, Vc, and VK. Studies have shown that VE and Vc can enhance the immune function of the body, improve the tolerance of chickens to various stresses, and promote recovery and growth after disease. VK can shorten the coagulation time and reduce blood loss, so it can relieve symptoms and reduce death in some diseases with bleeding symptoms.

Myth 2: Excessive use

The excessive addition of vitamins by farmers in production not only increases the cost of breeding, but also affects the health of the flock in severe cases. For example, when the feeding amount of vitamin D exceeds the feeding standard, a large amount of calcium can be transferred from the chicken bone tissue, and it can promote the absorption of calcium in the gastrointestinal tract, increase the blood calcium concentration, and deposit calcium on the arterial wall, joints, and renal tubules. , heart and other soft tissues, the clinical manifestations are loss of appetite, diarrhea, kidney stones, and sick chickens often die of uremia.

Misunderstanding 3: Blindly mixing

Farmers often use several drugs and vitamins mixed in drinking water when chickens are sick. When adding vitamins, attention should be paid to the antagonism between vitamins and between other drugs or minerals, such as vitamin B and amprolium should not be mixed, streptomycin and VC should not be mixed.

Misunderstanding 4: Inappropriate way of adding

In open drinking water, especially in summer, the quality of vitamins in the water declines rapidly. At this time, the added amount should be slightly higher than the prescribed amount, and it should be drunk quickly.

Misunderstanding 5: Improper purchase

There are many kinds of vitamins on the market, and the quality is uneven. Farmers will be limited by the level of awareness to choose inferior products, which affects the effect of vitamins.

In short, farmers should make reasonable choices according to the metabolic characteristics of various vitamins, the physiological characteristics of broilers in various periods and different feeding conditions in the breeding process. Blindly adding vitamins not only increases the cost of breeding, but also seriously affects the health of the entire flock.
