Cassava residue bio-polypeptide fertilizer additive and preparation method thereof

Abstract

The invention discloses a cassava residue bio-polypeptide fertilizer additive and a preparation method thereof. The bio-polypeptide fertilizer additive per 1 kg contains the following components: 650-800 g of cassava residue, 40-120 g of broken rice, 70-150 g of molasses, 0.8-2 g of Saccharomyces cerevisiae, 0.8-2 g of Enterococcus faecalis, and the balance of mixture of rice chaff and husk. The preparation method comprises: stirring the materials according to the above ratio, adding suitable water, and mixing well; packaging with fermented fertilizer bags, and fermenting at 25-35 DEG for 2-3 days or fermenting at 10-20 DEG C for 4-6 days to obtain the bio-polypeptide fertilizer additive. The cassava residue bio-polypeptide fertilizer additive has good taste, can significantly improve palatability of cassava residue, and increase feed intake and speed; feed nutrients can be significantly increased and can be converted into various completely nutritional effective amino acid components necessary to animals; feed digestion, absorption and utilization rate can be increased, producing performance is improved, and 10-25% of feed can be saved by long-term use of the additive.

Description

technical field [0001] The invention specifically relates to a cassava residue biological polypeptide feed additive and a preparation method thereof. Background technique [0002] There are a large number of starch factories in Guangxi, Guangdong, Hainan and other provinces and surrounding countries such as Vietnam and Cambodia. When cassava is used to process starch, a lot of cassava dregs will be produced. The main components of cassava residue are starch and cellulose, with a small amount of protein. Many farmers often use cassava residues as feed. [0003] Usually, farmers mix cassava residue with some feed to cook it and feed it to pigs. Simply using cassava dregs to feed pigs or mixing cassava dregs with feed to feed pigs, this kind of feed tastes poor, although it can fill the stomachs of pigs, but because pigs have extremely low nutrient digestion and absorption rate of cassava dregs themselves, and cannot It cannot play the role of promoting the growth of pigs; l...

Problems solved by technology

Simply using cassava dregs to feed pigs or mixing cassava dregs with feed to feed pigs, this kind of feed has a poor taste, although it can fill the stomachs of pigs, but because pigs have a very low rate of digestion and absorption of cassava dregs, they are not It cannot play a role in promoting the growth of pigs; long-term feeding will lead to slow growth and long hair of pigs, which is not only time-consuming and laborious, but also not worth the candle

[0004] In addition, many farmers do not store cassava residues, but pile up the cassava residues outside and simply cover them with film. The cassava residues will turn yellow or black within a day or two. After feeding animals, it often causes animal poisoning and frequent disease

[0005] Some farmers use glucoamylase to ferment cassava dregs to prepare feed: due to the single species of glucoamylase and low activity, the conversion time is too long, the effect is not obvious, and the cost is high. It takes 30 yuan for glucoamylase to process one ton of cassava dregs. ~60 yuan

Therefore, the application and promotion of this method are limited.
