The application of ammonium chloride and ammonium sulfate in fattening cattle ration.

In the daily grain of fattening cattle, two levels of chlorinated or sulfuric acid are added, which basically contains the same nitrogen source, energy and the same level of calcium, phosphorus and salt. Then the feeding experiment was carried out. After 112 days, the total weight gain of fattening cattle in each diet group was basically similar. Only those with a higher level of chlorination (3.0oz per day) were rewarded with higher feed costs, which cost the group about $3.77 more than the control group.
Experiment shows that when 1% of ammonium chloride and ammonium sulfate is added to the food, can be used as a source of non-protein nitrogen (NPN), found no ammonia poisoning. From the feed, weight gain cost and the incidence of liver disease, high levels of chloride in the diet group is more better.
American Crookshank used ammonium chloride and ammonium sulfate for fattening cattle diet nonprotein nitrogen source and used to control urinary calculi experiment, the results showed that the ammonium chloride to control the castration lambs urinary calculi more effectively, and the feed returns increase significantly, and ammonium sulfate on the improvement of the feed returns is a bit poor.
Clawson and Alsmeyer also reported that ammonium chloride was added to the feed diet of pigs, and the reward for raising pigs was also significant.
The above tests were carried out at cattle ranches in western Texas. A group comparison test was conducted with 46 mixed varieties of fattening cattle. The control diet basically adopts the livestock farm the provisions of the standard, and according to the food and drug administrative committee about the regulations on the use of ammonium chloride, excluding tetracycline or materials such as growth hormone: test the diet formula is calculated by the computer at the lowest cost. Basic ingredients have grain, purple flower and fat, the other supplementary cottonseed cake, urea, salt, calcium carbonate, apatite, choline, trace mineral elements and vitamin A, D and E, finally add chloride sulfate or the money. In order for each group to contain basic levels of calcium, phosphorus and salt, the amount of each component is different. The dry matter content of daily grain is 8 intestines, and the low level of ammonium chloride is 0.75 ounces (21.3 grams) per day, which is used for urinary calculi. The high level of chlorination per day was 3.0 ounces (85.1 grams), which was used to determine ammonia poisoning. And at the same time of the ammonium sulfate with equal nitrogen level to add, were 0.9 and 3.6 ounces. 112 days after the end of the trials, the carcass inspection, including the level of carcass, the determination of pesticide residues and liver disease symptoms, the results were not found ammonia poisoning phenomenon, and do not affect meat quality.
