Nipple type automatic drinker has many advantages compared to open drinking water equipment (drinking sink, etc.), such as simple and reliable water supply, the amount of water is just right, its closed water supply mode makes the drinking water fresh, clean, and does not need to clean the trough daily to reduce the disease. Spread and reduce feed wastage etc. Because of its precision design of the water supply system, it is made of stainless steel and plastic, so it has a long service life. Its biggest advantage is that the environment inside the chicken house is greatly improved, and the egg production in the flock is also greatly increased. 1 The method was used in a chicken farm of Guizhou Livestock Husbandry Technology Development Company. It was fed with 13 763 24-week-old Avian parent chickens in three broiler houses for a total of 84 days. 2 Results The amount of drinking water using nipple-type closed drinking water was 24.5% to 40.1% lower than that in open sink water (194.0: 257.0, 324.0 ml/day, daily). The reason for high open drinking water may be the collection and calculation of wasted water data deviations. It may also be that the environment in open drinking houses is poorer than that of closed drinking water, and chickens consume more water. Nipple type drinking chickens have a wasteful drinking rate of 0, basically no wastage, and the wastage rate of open drinking water is as high as 52.5%-61.4%. As nipple drinking water does not spill or spill, the grass is kept dry, and the use time of the grass in the house can be extended by 3 to 8 days. Therefore, the amount of bedding consumed is only 1/3-2 of the open drinking house. /5. The ammonia in the air in the house was reduced by 5.2%, hydrogen sulphide by 1.1%, and carbon dioxide by 12.7%. The reason for this is that after using nipple drinking water, there will be no spilling of drinking water, the mat grass will be dry, and the air environment in the house will be improved. The total number of bacteria in drinking water decreased and the number of E. coli decreased, indicating that closed drinking water is cleaner and healthier than open drinking water, which is more conducive to disease prevention and control. Purchasing and installing a nipple drinker requires a certain amount of expenditure, and about 10,000 chickens at the current price will cost about 5,000 to 10,000 yuan for a drinking nipple device. According to the calculation of the cost of drinking water and bedding, the cost of water and weeding should be reduced by 1.172-1.402 yuan per 1 000 chickens per day, and 10,000 breeding chickens can save water and grass by 4 years. 5 117.3 yuan, only these two cost savings in 1 to 2 years to meet the cost of assembling a nipple drinker.
Grain powder is a kind of solid powder obtained by spray drying after breaking the wall of grain with high protein content. It can also be made into small molecular peptides by enzymolysis. It is a good helper for food additives and nutritional supplements.
