As a good acidic inorganic salt, feed-grade ammonium chloride  has a good application in anti-heat stress of poultry.

Effects of feed grade ammonium chloride compound additive on broiler performance

Due to the high temperature of the broiler house, the pH value of the blood of the broiler chickens increases, which becomes alkalosis, which induces asthma, coughing, and disturbance of the internal secretion system of the broiler chickens. Appropriate ambient temperature is also an important condition for maintaining the health and high yield of laying hens. For adult chickens, the suitable temperature range is 8, 27 °C, and the suitable temperature for laying eggs is 13-23 °C. If the temperature exceeds 28 °C, the laying hens begin to experience heat stress. High temperature is the most serious stress hazard factor in my country's chicken industry, causing huge economic losses every year. The addition of feed-grade ammonium chloride can effectively reduce the pH value of poultry.

Ms. Zhao Yunhuan, associate professor of Henan Xinyang Agricultural College, etc., through a group comparison experiment of 300 280-day-old green-footed broiler breeders, fully proved that the compound additive containing feed-grade ammonium chloride is effective in resisting heat stress in poultry. effective effect.

The test was carried out from July 16 to August 22, 2005. The temperature range in the chicken house was (29.40±2.08)oC, and the average relative humidity was (79.35±5.27)%. The temperature and relative humidity in the chicken house were recorded daily at 8:00, 14:00 and 20:00.

Test Diet The basic diet used in the test was 60% corn with 40% concentrate; the nutritional levels were: crude protein 16.3%, calcium 3.26%, and total phosphorus 0.53%.

The diets of group I were supplemented with additive I on the basis of the basal diet. The composition of additives (addition ratio in the diet) is: sodium bicarbonate (0.3%) ammonium decachloride (0.5%) + potassium chloride (0.2%) + VC (0.025%) + VE (0.02%). Group II was the control group and was fed the basal diet.

The comparison results showed that the egg production rate of group I was 5.56% higher than that of group II. The average egg weights increased by 3.99% respectively, and the difference was extremely significant (P<0.01). Under the condition of the same feeding amount in each group, the feed-to-egg ratio decreased by 3.91% (P<0.05).
