Tylosin is a macrolide antibiotic with a bacteriostatic action against Gram-positive and Gram-negative bacteria like Campylobacter, Pasteurella, Staphylococcus, Streptococcus and Treponema spp. and Mycoplasma.
Tylosin Injection and powder are usded in gastrointestinal and respiratory infections caused by tylosin sensitive micro-organisms, like Campylobacter, Mycoplasma, Pasteurella, Staphylococcus, Streptococcus and Treponema spp. in calves, cattle, goats, sheep and swine.

Reasons and Prevention of Black Fungus Rotten Sticks in Bags
Causes of rotten rods 1. Improper selection of strains: Incorrectly cultivated strains that grow well on Duanmu are applied blindly to bagged black fungus without suitability and antifungal activity. 2. Inappropriate season arrangement: First, the spring planting black fungus inoculation period is too late or the autumnal black fungus inoculation period is arranged too early, during the period of raising bacteria, the temperature is too high, and various bacteria in the high temperature and high humidity conditions cause the infection. The second is the autumn planting of black fungus cultivation season is too late or black fungus inoculation period is too early to arrange the bacteria during the bacteria temperature is less than 20 °C, bacterial growth is slow, causing bacterial infections, resulting in bacterial rod decay. 3. Improper management during the period of culturing bacteria: The room temperature at the early stage of germination is low; the temperature rises at the late stage of germination and there is no timely ventilation and cooling; poor ventilation during germination will reduce the vigor of mycelia and cause bacterial infection. 4. The earmuffs have not been cleaned up or are close to the source of pollution: old earmuff sheds have been used in the production, and the earmuffs have not been cleaned up or have not been disinfected; some earmuffs are directly close to the pollution source or contaminated water has been used, causing the bacilli to rot. 5, improper water management during the ear. 6, pick ear late. Measures Taken 1. Selection of bacteria: choose bacteria age 35 days to 45 days, good bacteria, white, thick growth, strong resistance to impurities, high yield, large ears, hypertrophy, dark color, black fungus Strains. 2. Scientifically arrange the cultivation season: The black fungus should be cultivated in spring and autumn. The autumn inoculation period is generally arranged from August to September. When the temperature is lower than 30°C, the spring inoculation period is generally arranged to increase during the ten-day average temperature. To push forward at 20°C for 60 days to 65 days inoculation, different regions should be advanced or delayed according to different altitudes. 3, suitable temperature and culture: black fungus mycelium in the germination phase needs to be carried out under complete dark conditions, germination temperature between 5 °C ~ 36 °C, the optimum temperature is 24 °C ~ 28 °C, autumn plant black fungus In the early stage of germination and in the late period of spring fungus, when the temperature exceeds 25°C, ventilate the room at least twice a day or three times a day, and sunny ventilation must be performed in the morning and at night. In addition, during the early period of germination, black fungus is grown in the spring. When the temperature is lower than 20°C, the culture room should be warmed to make the temperature in the culture room reach 22°C~24°C. 4, management science: black fungus in different stages of growth of the temperature, humidity and ventilation requirements are different, in the formation of fungus primordium, to maintain the relative humidity of about 80%%, and moderate ventilation; in the formation of primordial differentiation, Coral ear buds are relatively young and maintain 80% to 90% relative humidity. At this time, if the humidity is too high, the water spray should be stopped immediately for 3 to 5 days. The ear base should be slightly dried before watering in the fruiting body. In order to promote the rapid growth of the ear, we must adhere to the principle of three dry and seven wet, increase ventilation, clear wet and dry, relative humidity maintained at 90%% ~ 95%%. 5, timely harvest: When the fruiting body ears fully expanded, the edge thinning, ear root contraction, harvested when eight mature. When harvesting, hold the fungus stick in one hand and pinch the ear root with one hand. Rotate it gently. Do not leave the ear pedicle on the fungus stick to avoid causing bacterial infection.
