Method for producing hay silage from pineapple peel

Abstract

The invention belongs to the field of animal feed production and particularly relates to a method for producing hay silage from pineapple peel; the method comprises the steps of (1) dewatering; (2) stirring; (3) filling; (4) storing. The pineapple peel silage of the invention is tender and juicy, is good in palatability and high in digestibility, has less nutrition loss of pineapple peel than traditional silage, has increased content of partial trace elements so that nutrients of silage are effectively guaranteed, is high in utilization rate, and may be used to make sure that cattle and sheep are ready for slaughter 15-20 days earlier.

Description

technical field [0001] The invention belongs to the field of animal feed production, in particular to a method for making semi-dry silage from pineapple peel. Background technique [0002] Semi-dry silage, also known as low-moisture silage, is a kind of prepared feed that is dried and stored in airtight cellars and towers after the raw materials have been dried to an appropriate water content. This kind of feed has high dry matter content and rich nutrition. Aromatic taste and good palatability. [0003] Due to the high moisture content of conventional silage, the surface layer is prone to mold and contains butyric acid during storage. On the contrary, semi-dry silage can inhibit the deamination of amino acids when stored with low moisture content, and there is almost no butyric acid, and the amount of ammonia gas is very small. , the nutrient loss is less, the utilization rate is improved, the dry matter loss of conventional silage is more than 10%, because there are solub...

Problems solved by technology

[0004] Pineapple peels are leftovers from the production of canned pineapple, and are mostly treated as waste. However, it has been determined that pineapple peels have high soluble sugar content, rich nutrition, sufficient material sources, and economic benefits. Discarding them everywhere will waste a lot of biological resources and easily cause ecological damage. Due to the destruction of the environment, pineapple peel can be used as a feed source for cattle, but because pineapple peel has the characteristics of water content, sugar content, and perishability, it is necessary to carry out silage treatment of pineapple. At present, there have been some research reports on pineapple silage , such as the patent of application number 201410213193.9 "A kind of silage mixed with king grass and pineapple peel and its preparation method", the king grass and pineapple peel are mixed for silage, but in the silage process, the lactic acid bacteria in it react freely, and there are certain limitations Due to the improper control of the amount of lactic acid produced by natural fermentation, it may cause some digestive and metabolic disorders after feeding silage, such as acidosis and reduced milk fat rate. Therefore, how to prepare pineapple peel into semi-dry silage, And strictly control the fermentation conditions in each fermentation period to ensure the quality and safety of silage is the current research focus in the field of cattle breeding
