Embodiment 1

[0071] Select 4 farms in the United States, 4 chicken houses / farms, and use acidifier NaHSO 4 Before, the average outdoor temperature of the two farms was -6°C, and that of the other two was 10°C. In each farm, two houses are used as the acidifier test group, and the addition amount is 25kg / 100m 2 ; The other two groups were the control group, and the litter was not treated. The area of ​​all chicken houses is equal to 12.9mX152m. When the acidulant is applied, the indoor temperature is 32°C, and the litter temperature is 26-30°C. The service cycle of litter ponds in each farm is 2-13 groups.

[0072] Such as figure 1 As shown, the test results: Compared with the control group, the average energy consumption of the chicken house using the acidifier was $783, ($1.25 / gallon of propane)

[0073] Such as figure 2 As shown, compared with the control group, the chickens in the group applying the acidulant only had significant weight gain. The flock can use more energy to gro...

Embodiment 2

[0077] Two addition ratios of acidifier NaHSO were carried out on 4 farming farms in the United States: 2 northern farms and 2 southern farms 4 , the dosage is respectively: 24.5kg / 100㎡ and 49kg / 100㎡. Before use, the ammonia gas value of the two northern farms was 120ppm, the ammonia gas value of one southern farm was 160ppm, and the ammonia gas value of the other southern farm was 300ppm, and the acidifier NaHSO was applied at 24.5kg / 100㎡ 4 Afterwards, the ammonia value in the northern farm dropped to 41.5ppm, and the acidifier NaHSO was applied at 49kg / 100㎡ 4 The northern farm ammonia value dropped to 31.5ppm. In the application of 24.5kg / 100㎡ acidifier NaHSO 4 Afterwards, the ammonia value of the southern farm dropped to 26.3ppm, and the ammonia value of the southern farm where 49kg / 100㎡ of acidifier was applied dropped to 24ppm. Such as Figure 5 shown.

Embodiment 3

[0078] Embodiment 3 (broiler litter test)

[0079] Chicken house area: 2000㎡, number of broilers: 20,000, litter thickness: 2-3cm, original litter replacement frequency: 10 days / time, test cycle: 100 days.

Abstract

The invention discloses a method for controlling the concentration of ammonia gas in a breeding house, and the method comprises the following steps: (1), cleaning and disinfecting the breeding house;(2), spraying an acidifying agent NaHSO4 on the ground of the breeding house, wherein the usage amount is 10-100kg / 100m2; (3), installing a cushion material on the ground of the breeding house; (4), uniformly spraying the acidifying agent NaHSO4 on the cushion material in 2-24 hours before the entry of poultry into the breeding house, wherein the usage amount is 10-100kg / 100m2; (5), monitoring theconcentration of ammonia gas in the breeding house in real time after the entry of poultry into the breeding house: spraying the acidifying agent NaHSO4 on the cushion material again for acidifying if the concentration of ammonia gas is not less than 25ppm, and the usage amount is 10-100kg / 100m2. The method can be used for cushion materials of various animals, such as the cushion materials of breeding farms of the commercial chickens, ducks, broiler chickens, breeding hens, turkeys, commercial pullets, laying hens, quails, pheasants, ducks, beefs and dairy cows.

Description

technical field [0001] The invention relates to a method for treating litter ammonia accumulation in breeding cages and reducing indoor ammonia discharge concentration during breeding production operations in the animal breeding industry, and specifically relates to a method for controlling indoor ammonia concentration in breeding cages. Background technique [0002] With the continuous improvement of the scale and intensification of animal husbandry production, the ammonia gas produced by livestock and poultry and their waste in the animal breeding industry is increasing day by day. Ammonia gas is a colorless gas with a special pungent odor. Soluble in water, the density is 0.596. In aquaculture production, the source of ammonia is mainly the decomposition products of nitrogen-containing organic matter, such as feces, feed and bedding, which are produced by the decomposition of anaerobic bacteria due to rot, especially in warm, humid, high stocking density, and repeated use...
