Use of wet fermented protein feed in high-efficiency mutton sheep fattening technology

Abstract

The invention relates a use of wet fermented protein feed in a high-efficiency mutton sheep fattening technology and especially relates to a production technology of the wet fermented protein feed and a use method of the wet fermented protein feed in high-efficiency mutton sheep fattening. The production technology comprises the following steps of respectively crushing corn, soybean meal, sodium bicarbonate, mineral matters, trace elements and composite probiotics, mixing the crushed materials according to a certain ratio, putting the mixture into a bag, mixing wet vinasse slag and dense vinasse slurry according to a certain ratio, carrying out seal preservation, wherein the shelf life is more than 6 months, mixing the above two materials according to a mass ratio of 1: 4, adding water into the mixture, adjusting a pH value of the mixture to 6-7, and carrying out standing fermentation for 4-8h to obtain the wet fermented protein feed. 1.5-2kg of the wet fermented protein feed is fed to the mutton sheep each day by 2 or 3 steps. In feeding, forage grass is used and then the mixed wet fermented protein feed is poured on the forage grass. The mutton sheep eats the forage grass mixture so that mutton sheep weight is increased according to a ratio of 0.4-0.5kg / d.

Description

technical field [0001] The invention relates to a production process and a use method of a feed, in particular to a production process of a wet-state fermented protein feed and a use method for high-efficiency fattening of mutton sheep. Background technique [0002] In the microbial fermentation liquid in the alcohol fermentation industry, after the alcohol is extracted, the remaining liquid is the fermentation raffinate. The fermentation residue has a high content of organic substances and cannot be discharged. Now it is mostly dried and used as feed raw materials. Alcoholic fermentation raffinate has a low solid content, mostly 10-12%, and cannot directly enter the drying process. It needs to be separated and concentrated to make the solid content reach about 35%, and then enter the drying process. [0003] There are two kinds of substances after concentration, one is the filter residue after plate and frame extrusion, which is in a solid state, called distiller's grain w...

AI Technical Summary

Problems solved by technology

This kind of drying process not only has high cost (600 yuan per ton of drying and drying cost), but also because of the high-temperature evaporation treatment during drying, so its nutritional value is lost and reduced (about 10%). Volatile components enter the atmosphere and cause certain air pollution
