Method for feeding live pigs through full-plant green corn bundled fermentation and assorted harvester

Abstract

The invention discloses a method for feeding live pigs through full-plant green corn bundled fermentation and an assorted harvester. The harvester comprises a vehicle body, a harvesting mechanism, a chopping mechanism, a delivering mechanism, a compression bundling mechanism, a juice recycling and spraying mechanism and the like. When the harvester walks forward in a field, full-plant green corn is slotted after being cut from the root and then enters a compressing cavity of the compression bundling mechanism, an auxiliary mixed with a fermentation inoculant on the harvester synchronously enters the compression cavity to be compressed and bundled, extruded juice is sprayed to the surface of the bundled full-plant corn, and then the corn is packed into a plastic sealing bag containing a unidirectional breather valve, and is put on the field after being covered with a plastic woven bag; the corn is transferred to a suitable place from the field, and is mixed with other feed after being stacked, stored, fermented, pulped and smashed to feed live pigs. Harvesting, smashing, mixing with inoculating microbes, compression bundling and bagging of the full-plant green corn are all completed in one harvester, and the full-plant green corn feed in accordance with live pig feeding is obtained through integration production.

Description

technical field [0001] The invention relates to a method for wrapping and fermenting whole-plant green corn to feed pigs and a matching harvester, belonging to the technical field of animal husbandry. Background technique [0002] my country's main crops are corn and wheat. Green corn and green wheat, cheap and juicy. Feeding pigs with green crops can significantly reduce feed costs and improve breeding efficiency. After corn silage, it is mainly fed to herbivorous animals such as dairy cows and beef cattle, but it is not widely used in feeding pigs. Chinese patent 201310724893.X discloses a special ration for lean growing and finishing pigs and its production method. In this method, the whole plant corn stalks at the milk maturity stage are first shortened to 5.0 cm, and then crushed to about 0.5 cm. The silage tank is closed for fermentation, and the silage matures after 45 to 60 days. No exogenous bacteria and fermentation aids are added to the corn stalks during sila...

AI Technical Summary

Problems solved by technology

[0004] The existing corn stalk mechanical bundling and coating technology is an integrated production of corn harvesting, cutting, wrapping and fermentation, which is suitable for cattle and sheep, but not suitable for pigs. The main reasons are: first, pigs are omnivores, The ability to utilize crude fiber is low. Cattle and sheep are herbivores and mainly eat grass. Generally, the silage corn stalks eaten by cattle and sheep can be crushed to about 2cm, but pigs cannot; second, the whole corn used by pigs is milk cooked Harvested at the early stage of wax ripening, the moisture content is high; the whole plant corn used for cattle and sheep is mainly in the late wax ripening st...
