E. coli, refractory enteritis,
It has a wide antibacterial spectrum, and has a strong antibacterial effect on gram-negative bacteria, especially on other antibiotic-resistant pathogens such as Escherichia coli and Salmonella, and also has a good antibacterial effect on gram-positive bacteria (some streptococcus), treponema and some mycoplasma.
Function of the attending
To treat diseases caused by E. coli and other sensitive bacteria in poultry and pigs. 1. It has special effect on chicken Escherichia coli, Salmonella and Mycoplasma. 2. It can treat diarrhea caused by enterobacter calves and salmonella
1. Ampramycin can be used by drinking water, injection and mixed feeding methods to prevent and treat colibacillosis and salmonellosis in poultry. Poultry drinking water administration, add this product 250 ~ 500 mg (250 thousand ~ 500 thousand potence unit) per liter of water, continuous use for 5 days, to prevent chicken colibacillosis and salmonellosis, stop administration 7 days before market; Because the bioavailability of the drug administered by drinking water was only 11.0%, the protection rate against acute colibacillosis in chicks was limited. Water administration is more suitable for the control of intestinal infection or natural infection, while injection therapy is better for systemic acute infection. Ampramycin can be injected intramuscular at 10 mg/bird for 5 days, once a day, and can completely protect chickens infected with coliform and Salmonella typhimurium. 5 g (5 million units) per 1 000 kg feed for broilers can promote the growth and increase the weight gain of broilers during the whole period of 0 to 6 weeks of age, especially during the early growth period (0 to 21 days of age)
2. Pigs were mixed with 100 grams per 500 kg feed for 7 days. Mix the chicken and drink 100 grams of water chicken for each 200 kg for 5 days
1. It has a synergistic effect in combination with penicillin or cephalosporins, and is not suitable for use with amino glucosides (to enhance toxicity). 2.
