Chlortetracycline is obtained from the culture broth of Streptomyces. Commonly used hydrochloride, its aqueous solution is the most unstable among tetracyclines, and it is quickly destroyed in neutral or alkaline solutions. The antibacterial effect is the same as oxytetracycline, which is not used for systemic infections due to its strong irritation. Mostly used as raw materials for external preparations and feed pharmaceutical additives.
The chlortetracycline premix is brown or tan powder or granules, which belongs to the tetracycline broad-spectrum antibiotics. In addition to its effect on Gram-positive bacteria and Gram-negative bacteria, it also has inhibitory effects on Rickettsia, Chlamydia, Mycoplasma, Treponema, Actinomycetes and some protozoa. It is used to promote growth of broilers and piglets; to treat diarrhea in weaned piglets; to treat swine asthma and proliferative enteritis.
Functional indication
1. Diarrhea caused by Escherichia coli or Salmonella, such as yellow and white dysentery of piglets and white dysentery of chicks.
2. Swine pneumonia and avian cholera caused by Pasteurella multocida.
3. Controlling swine proliferative enteritis (ileitis) caused by Lawsonia intracellularis.
4. Control leptospirosis caused by leptospirosis pomona (reduce the incidence of abortion and leptospirosis).
5. Reduce the incidence of cervical lymphadenitis (jaw abscess) caused by group E streptococci.
6. Swine asthma caused by mycoplasma and chronic respiratory diseases of chicken.
Aureomycin as antibiotic for feed additives
1. Chlortetracycline for feeding can promote the growth and development of livestock and poultry, increase the feed return rate by more than 30%, and increase the brooding rate by 6.23% for 0-8-week-old chicks, and increase the weight by 11.94% to prevent chlortetracycline-sensitive bacteria. Added in the feed of chicks and chicks can promote growth and development, shorten the breeding period and improve the breeding rate.
2. It can inhibit chlortetracycline-sensitive bacteria. Adding a small dose can prevent diseases, and increasing the dose can treat diseases.
3. The low-dose addition can promote the intestinal absorption function, thereby improving the feed conversion rate.
4. Chlortetracycline is a kind of antibiotic with high safety, which can produce efficacy only when added in low concentration, and no toxic and side effects can be produced when the dose is increased by 18 times. Long-term use, long-term effect, no drug resistance.
Chlortetracycline for swine
Chlortetracycline for pigs is helpful to improve the resistance of pigs, inhibit the growth of harmful microorganisms in the digestive tract, improve the penetration and absorption of nutrients; increase appetite, promote growth, stimulate development, increase feed conversion rate, and reduce feed costs. The specific role of chlortetracycline in pig feed is as follows:
①Reduce weaning stress and group stress.
② Reduce respiratory diseases caused by excessive feeding density in the middle of fattening.
③ Optimize pig intestinal health, improve feed conversion rate, and reduce feed-to-meat ratio.
④Promote growth, shorten the feeding cycle and save costs.
⑤ Reduce diseases of sow reproductive system.
⑥Reduce the occurrence of intestinal and respiratory diseases and save medicine costs.
