Antibiotic:
A drug used to treat bacterial infections. Antibiotics have no effect on viral
infections. Originally, an antibiotic was a substance produced by one
microorganism that selectively inhibits the growth of another. Synthetic
antibiotics, usually chemically related to natural antibiotics, have since been
produced that accomplish comparable tasks.
Antimicrobial:
A drug used to treat a microbial infection(antibiotic drugs).
"Antimicrobial"
is a general term that refers to a group of drugs that includes antibiotics,
antifungals, antiprotozoals, and antivirals.

Winter chicken fill light technology
With the advent of winter, the sunshine time is gradually shortened, and the effect of light on the egg production rate of the flock is greater. Practice has proved that providing artificial light to supplement the lack of sunshine is an easy way to maintain a high rate of egg production. A good way to go. First, the light affects the reasons for the egg production rate. Autumn and winter festivals shorten the time, the effect of light on the chicken body is reduced, so that the secretion of gonadotropin in the anterior pituitary of chickens is reduced, resulting in a decrease in the egg production rate of chickens. Second, the appropriate lighting time for chickens. After the flocks have been put into production, the appropriate daylight hours should be 14 to 16 hours, and the illumination should be about 10 lux (equivalent to 2 meters above the ground, with 1 watt of light per 0 to 37 square meters). The lighting time cannot be arbitrarily changed. Especially in the late stage of laying eggs, it is not appropriate to reduce the light intensity or shorten the illumination time. In other words, the light can only be increased and cannot be reduced, otherwise the egg production rate will be greatly reduced. Third, provide artificial lighting method. Generally, artificial light is provided starting from natural light for less than 12 hours, and the daily lighting time is made up to 14 hours. To supplement the lighting, it is better to turn on the lights twice a day, that is, turn on the lights at 6 o'clock every morning until dawn, and turn on the lights at night until 20 o'clock in the evening. When supplementing the lighting, the power supply must be stable. The lighting should be about 3 watts per square meter. The lamp should be about 2 meters away from the ground. The distance between the lamp and the lamp should be about 3 meters. The light should be evenly distributed in the house, and the trough and drinking water should be uniform. The device should be placed under the bulb. Fourth, pay attention to matters. For poor health, poor development, lighter weight, and less than 6 months of age, the artificial supplementation of light is generally not performed or supplemented for a period of time. Otherwise, the goal of increasing egg production rate cannot be achieved. The temporary increase will also soon be premature, but it will reduce the egg production rate throughout the year. ?
