How to use chicken feed additives?

Feed additive is an inevitable raw material used in modern feed industry, which has obvious effect on strengthening the nutritional value of basic feed, improving animal production performance, ensuring animal health, saving feed cost, and improving the quality of animal products. Let's take a look at how to use common chicken feed additives.

Antibiotic additive

Antibiotics have bacteriostatic effect. when some antibiotics are added to the diet as additives, they can inhibit the activity of harmful bacteria in the intestinal tract of chickens, resist a variety of respiratory and digestive system diseases, improve feed utilization, and promote weight gain and egg laying. The effect is more obvious especially when the chicken is in adversity. Commonly used antibiotic additives are penicillin, oxytetracycline, chlortetracycline, neomycin, tylosin and so on. When using antibiotic additives, we should pay attention to the alternation of several antibiotics so as to avoid drug resistance of harmful microorganisms in chicken intestines and reduce the effect of prevention and control. In order to avoid excessive drug resistance and product residues, it should be used at intervals, and the addition amount should be strictly controlled, and antibiotics that are commonly used by humans and animals should be used less or carefully.

Deworming health additive

In the parasitic diseases of chickens, coccidiosis has a high incidence and great harm, so special attention should be paid to prevention. The commonly used anti-coccidiosis drugs are dysentery, amproline, salinomycin, monomycin, chlorophenylguanidine, etc., and should be used alternately to avoid drug resistance.

antioxidant

In the process of feed storage, the addition of antioxidants can reduce the oxidation loss of vitamins, fats and other nutrients, such as adding 200 grams of sandoquine per ton of feed for one year, the loss of carotene is 30%. The loss of 70% without antioxidants can maintain the digestibility of crude protein by adding antioxidants to fatty fish meal, and the digestion, absorption and utilization efficiency of various amino acids will not be affected. The commonly used antioxidants are sandoquine, ethylated hydroxytoluene, butylated hydroxymethoxybenzene and so on, with a general addition of 100mg / kg.

Anti-mildew agent

In the process of feed storage, in order to prevent the feed from mildew deterioration and maintain good palatability and nutritional value, anti-mildew agents can be added to the feed. The commonly used anti-mildew agents are sodium propionate, calcium propionate, sodium dehydroacetate, etc., adding 1 kg of sodium propionate per ton of feed, 2 kg of calcium propionate per ton of feed, and 200 grams of sodium dehydroacetate per ton of feed.

Egg yolk hyperchromic agent

After adding egg yolk hyperchromic agent to feed, the color of egg yolk can be improved, that is, the color of egg yolk changes from light yellow to dark yellow, and the commonly used egg yolk hyperchromists are lutein, Lukangding, red pepper powder, etc., such as 200,300g red chili powder in every 100kg, continuous feeding for half a month, it can keep the yolk dark yellow for 2 months, at the same time, it can also enhance chicken appetite and improve egg production rate.
