- Birds go through several moults from brood to maturity in chicks cage
From brooding to body maturity, feathers need to be removed 4 times, respectively at 4-5 weeks, 7-8 weeks, 12-13 weeks, and 18-20 weeks. At this stage, it is necessary to strengthen nutrition, especially protein ( Sulfur-containing amino acids), increase temperature in chicks cage, prevent respiratory tract!
- Egg laying time of poultry in chicks cage
Theoretically, 12:00 noon every day is the time for yolk release or ovulation, 13:00-17:00 is the time for egg white and eggshell membrane formation, 16:00-8:00 is the time for eggshell formation, and 8:00 The left and right is the egg laying time, and 4:00-20:00 is the light time of the chickens and the feeding time of the chickens in the chicks cage.
- The acidity and alkalinity of the digestive tract of poultry
All parts of the digestive tract of poultry are acidic, and the pH value is the highest in the intestinal tract. The alkalinity of the intestine is neutralized by bile, so it is acidic.
- The difference between original powder and finished drug
Since 2005.10.1, the management of original powder is prohibited. Due to the incorrect use of the original powder, the rapid emergence of drug-resistant strains, the mutation speed of bacteria and viruses is much faster than the research and development speed, the disease is more difficult to treat, and a vicious circle occurs. Escherichia coli is becoming more and more difficult to treat.
Original powder: a. low solubility; b. large side effects (nephrotoxicity); c. easy to produce drug resistance; d. large dosage.
Finished drug: a. Easily soluble; b. The formula is reasonable, the effect is fast, good, and the duration of the drug effect is long; c. There is no drug residue and drug resistance.
- Characteristics or properties of chloramphenicol
The principle of its ban is that it can cause irreversible damage to the bone marrow, affect hematopoietic and immune organs, and the residue can cause aplastic anemia, leukemia, etc.
Features: heat-resistant, boiled for 5 hours without damage, easy to fail in case of alkali. Based on such properties, it is added to some traditional Chinese medicines to enhance the effect and increase the amount of mixing. But for flocks, it can seriously affect the production performance of chickens.
- Use of Mycoplasma Drugs
Current drugs for the treatment of mycoplasma: macrolides: erythromycin, clarithromycin, tylosin, tilmicosin, azithromycin; tetracyclines: oxytetracycline, doxycycline; lincomycin, fluoroquinolones kind.
Clarithromycin is the most widely used mycoplasma drug at present, and its effect is better than azithromycin. Enrofloxacin is more familiar, in fact, the effect of mycoplasma is quite obvious. It is recommended that everyone use the in chicks cage to use the right time. Doxycycline has been used less in the past two years, and is now more sensitive and less expensive.
