Meat pigeons generally grow to 20-25 days of age and can be marketed when they weigh 350-500 grams. However, in order to improve the quality of the pigeon's flesh, enhance its palatability, and obtain better economic benefits, it is generally done 5 to 7 days before the sale. Fattening object For those who are 15-20 days old and have a body weight of 350 grams or more, healthy and non-disabled pigeons can be used as fattening objects. Generally, large, muscular, and smooth feathers are preferred. However, over 20 days of age, the body weight is still less than 350 grams, or the body-wounded pigeons cannot be fattened. Fattening loft For a few pigeons used for fattening, the old houses are generally used as a finishing house. If the number of fattening pigeons is large, a special breeding loft should be built. The form of the rearing lofts can be referenced to a double-row breeding loft, but the height can be shorter. The windows can be smaller, smaller and shaded with curtains. The air must be circulated and refreshed. The ground is best to be tiled or cemented, and the room temperature should be kept at about 25°C. Fattening equipment Including fattening bed, feeding device, immersion box and so on. The fattening bed is used extensively in our country. It is usually 70 centimeters in height, 30 centimeters in height and 70 centimeters in width. The length is the same as the loft. The middle of the bed is divided into small squares with bamboo plates, each of which is 1 meter long. There are 20 pairs of fattenable pigeons. Because forced fattening is like forced feeding of ducks, there are several ways to force feeding. Generally include hand feeding, mouth blowing, feeding with a funnel, feeding with a syringe, feeding with a feeding device, and the like. The ones that are more commonly used today are those modified by feeding feeders for ducks. This feeder is simple in structure and easy to clean. However, care should be taken when filling, and the action should be light and fast, avoiding the mouth of the pigeon and the tongue of the pigeon. The dipping pots are used to soak the fattening feed, making it soft and easy to be digested and absorbed by the pigeons. Dip basins are generally made of tiles or plastic basins for easy cleaning and disinfection. Finishing feed Mainly include corn, wheat, brown rice, rapeseed, and legumes, etc. Generally, it is appropriate to use small grain seeds. If using the matching feeds, the effect of making smaller grains and feeding is better. The general formula is: corn, wheat and other energy feed 75% -80%, beans accounted for 20% -25% of total feed. In winter, the nutritional value of the diet is higher, especially the energy content, and the water temperature of the diet during feeding must not be lower than 25°C-35°C. The larger particles of the feed should be crushed into small particles and soaked to soften them before feeding. In general, cereals can be soaked in water for 1 day and night. Fattening method Put the pigeons to be fattened on the fattening bed and fatten them by the method of feeding. Keep the temperature at about 20°C. Generally, each pigeon is fed 50-100 grams of feed or half a dozen feeds at a time and fed twice a day. After the feeding, it is necessary to ensure that the environment inside and outside the home is quiet, letting the curtains down and allowing them to sleep.
KN95 Masks are anti-virus. KN95 masks are similar to N95 masks, except that one is a Chinese standard and the other is an American standard.
If there are two numbers of 95, it means that the protective ability of this mask is above 95%. That is to say, for tiny substances larger than 0.3 micrometers, the mask has a defensive ability of more than 95%, and it can block tiny substances larger than 0.3 micrometers outside the mask. Viruses and bacteria are generally larger than 0.7 micrometers. Therefore, using a mask such as KN95 can effectively protect against viruses.
