With regard to the nutritional needs of ducks, exploration is still ongoing and no standard has yet been established. Due to the large differences in duck conditions and feed resources, it is not possible to apply one or two recipes to any area. According to the nutrition requirement list of ducks and ducks in different periods, several feed formulation examples are introduced for reference use and rushed to the grazing land for free admission. Suitable for grazing without crops and empty pasture. Timing grazing method. Daily graze 6 times, 3 hours each time. Suitable for grazing in scattered plots Each grazing can not make the ducks over-fatigue, should pay attention to rest. After each grazing, the ducks should be fully bathed, dried and feathered, and fully rested. Keep abreast of the weather and prevent the loss of ducks caused by thunderstorms. At the same time, pay attention to the health of grazing land and do not damage crop seedlings. House keeping. The breeding of sheds is not based on grazing, but rather on feeding in duck houses. This method can artificially control environmental conditions. It is less constrained by nature and conducive to scientific duck breeding. It can also reduce the chances of infectious diseases and the occurrence of poisoning and accidents. Ducks housed in pens should provide a variety of nutrients that are adequate and complete, and in particular nutrients necessary for the growth of bones and feathers must be met. The feed formulation of bred ducks should be formulated according to the growth and development rules, and according to different breeds and feeding purposes, appropriate restrictions should be adopted for feeding, increasing the ratio of green and rough feeds, and adding appropriate amount of animal feed to promote feed digestion and absorption. In the rearing period, each duck needs about 3 kg of feed, which is fed 6 times per day and night. The interval between feedings should be as equal as possible. Concentrates are mostly fed with powdered ingredients and are supplied with clean water. When keeping a pen home, management should pay attention to the reasonable density according to the season and the individual size of the duck. Generally, 1 meter can be guaranteed at the end of the breeding period. In addition, attention should be paid to exercise in order to promote the growth of bones and muscles, prevent excessive fat, and enhance physical fitness. The method is to regularly drive the laps in the sheds every day for 23 minutes each time, and exercise 4 times in the day. You can also drive away in the plaza or nearby places. Light during the breeding period needs to be guaranteed for 3 hours a day and should always be kept low light at night. The intensity of 3 watt meters is appropriate. In case of power outage, the candle light should be added in time. China Agricultural Network Editor
Tuberculosis (TB) is a potentially fatal contagious disease that can affect almost any part of the body but is mainly aninfection of the lungs. It is caused by a bacterial microorganism, the tubercle bacillus or Mycobacterium tuberculosis.Although TB can be treated, cured, and can be prevented if persons at risk take certain drugs, scientists have never comeclose to wiping it out. Few diseases have caused so much distressing illness for centuries and claimed so many lives.
