Embodiment 1

[0018] In this example, a beef cattle with a weight of 100 kg needs to be fed with alkalized feed every day. Take 8 kg of alkalized straw as an example, and then take the following amount of glutamic acid fermented yeast liquid containing different amounts of chlorine elements and mix well Or evenly sprayed in the alkalized straw feed, replacing the original beef cattle with a weight of 100 kg must be given 25 grams of salt (sodium chloride) a day. Wherein, the composition of glutamic acid fermented yeast liquid is:

[0019] (1) Parameters of glutamic acid fermentation yeast liquid: pH value 2.9, chlorine element 2%, solid content 10%, sugar 1.5%, nitrogen 1.5%, glutamic acid 0.5%. A beef cattle weighing 100 kg needs to be fed with 8 kg of alkalized feed every day, and the maximum amount of feeding yeast liquid with 2% glutamic acid containing 2% chlorine without concentrated treatment is allowed to be 625 grams per day. The weight ratio of sour yeast liquid to feed: 7.8%.

Embodiment 2

[0023] In this example, a 100-kg beef cattle needs to be fed alkalized feed every day. Take 8 kg of alkalized straw as an example, and then take the following amount of glutamic acid fermented yeast liquid containing different amounts of sulfur and mix well Or evenly sprayed in the alkalized straw feed, instead of the original 100 kg beef cattle allowed to eat a maximum of 1.0 grams of sodium sulfate a day.

[0024](1) Parameters of glutamic acid fermentation yeast liquid: pH value 2.9, sulfur element 2%, solid content 10%, sugar 1.5%, nitrogen 1.5%, glutamic acid 0.5%. 37 grams of non-concentrated glutamic acid fermented yeast liquid.

[0025] (2) Glutamic acid fermentation yeast liquid parameters: pH value 3.19, sulfur element 12%, solid content 60%, sugar 25%, nitrogen 20%, glutamic acid 15%, concentrated glutamic acid fermentation yeast liquid 6 gram.

[0026] (3) Parameters of glutamic acid fermented yeast liquid: pH value 3.1, sulfur element 6%, solid content 25%, suga...

Embodiment 3

[0028] In this example, a beef cattle weighing 100 kg needs to be fed with alkalized corn stalks feed every day, and the alkalized feed is obtained by soaking corn stalks with potassium hydroxide. Take 8 kg of alkalized cornstalk as an example, and mix the following or the mixed solution of glutamic acid fermented yeast liquid containing 2-12% chlorine element and glutamic acid fermented yeast liquid containing 2-12% sulfur element respectively Spray evenly or uniformly in alkalized straw feed. Instead of giving 25 grams of salt (sodium chloride) and only 1.0 grams of sodium sulfate to a beef cattle with a weight of 100 kg a day.

[0029] (1) 625 grams of unconcentrated mixed liquor, including 588 grams of glutamic acid fermented yeast liquid containing 2% chlorine element and 37 grams of glutamic acid fermented yeast liquid containing 2% sulfur element.

[0030] (2) 104 grams of concentrated mixed liquor, including 98 grams of glutamic acid fermented yeast liquid containing ...

Abstract

The invention discloses a method for using non-protein nitrogen feed additives, which is characterized in that when alkaline feed or an alkaline non-protein nitrogen feed additive is fed to ruminants, slightly acidic glutamic acid fermentation mother liquor which has a pH between 2.9 and 3.19 and contains chloride ions and / or sulfur ions is sprayed in alkaline feed or is evenly blended with the alkaline non-protein nitrogen feed additive, and chloride ions in the glutamic acid fermentation mother liquor with the pH between 2.9 and 3.19, and / or sodium ions, calcium ions, potassium ions and ammonia in sulfur-ion neutralized alkaline feed, or ammonia in the alkaline non-protein nitrogen feed additive are combined to form salt. When the method is used to manufacture alkalized feed, added salt can be reduced, and sulfate does not need to be added so as to reduce cost for manufacturing the alkalized feed. Moreover, the method also reduces the alkalinity of the alkaline alkalized feed or the alkaline non-protein nitrogen feed additive, and improves the palatability of cattle or sheep fed on the feed or the non-protein nitrogen feed additive.

Description

technical field [0001] The invention relates to the technical field of feed, in particular to a method for using a non-protein nitrogen feed additive. Background technique [0002] In addition to feeding normal feed for beef cattle fattening, some advanced feed additives have been developed and applied in recent years. Non-protein nitrogen refers to the use of industrially produced non-protein nitrogen. Cattle can effectively use this through the action of rumen microorganisms. The nitrogen in the nitrogen compound synthesizes high-quality bacterial protein, which enters the rumen and small intestine, is decomposed into amino acids by digestive enzymes, and is absorbed through the intestinal wall. Non-protein state nitrogen compounds mainly include the following types: 1. Urea: The amount of urea generally accounts for 1% of the dry matter of the diet or 2% of the mixture, and does not exceed 1 / 3 of the protein requirement. Feeding amount per head per day: 30-50 grams for c...
