Embodiment 1

[0018] Six Hu sheep with permanent rumen fistula were selected and randomly divided into 2 groups with 3 sheep in each group, and each sheep was a repetition. The control group was fed the basic diet, and the experimental group was fed the diet supplemented with 3% calcium nitrate. The test was carried out for 30 days in two phases, each period was 15 days, of which the transitional period (changing the feed and adapting the Hu sheep to the test conditions and feed) was 10 days, and the trial period (officially started to collect samples) was 5 days. The Hu sheep ate freely. The test was completed at the Gaolan Experimental Station of the Institute of Environment and Engineering in Cold and Arid Regions, Chinese Academy of Sciences. Before selecting the sheep for testing, use a strong disinfectant to disinfect the sheep house used in the test in all directions. After the disinfection, let the disinfectant in the house volatilize for a period of time before entering the sheep t...

Abstract

The invention provides application of nitrate in relieving acidosis of Hu sheep. According to the invention, calcium nitrate is added into the feed to feed Hu sheep, so that the ratio of acetic acid / total acid in rumen fluid and the content of ammoniacal nitrogen are increased, and treatment and time show significant interaction; the calcium nitrate can maintain the pH value of the rumen fluid of the Hu sheep at a relatively high level and relieve acidosis of the Hu sheep.

Description

technical field [0001] The invention belongs to the technical field of animal husbandry, and in particular relates to an application of calcium nitrate in alleviating acidosis of lake sheep. Background technique [0002] In the prior art, nitrate can not only be used as a source of non-protein nitrogen, but also can change the environment and serum indicators in the gastrointestinal tract of ruminants. The homeostasis of the rumen environment in ruminants is critical to their own health. After animals eat rations containing nitrate, the nitrate is first reduced to nitrite through the action of microorganisms in the rumen, and finally ammoniacal nitrogen is formed. In this process, the reduction of nitrate needs to consume hydrogen, and since the synthesis of propionic acid also requires the participation of hydrogen, the reduction of hydrogen will inhibit the production of propionic acid and promote the production of acetic acid. In addition, the reduction of hydrogen also...
