Mixed pellet feed directly prepared from optimally-proportioned dry matter of whole-plant corn in squeezing and extruding mode

Abstract

The invention discloses a mixed pellet feed directly prepared from optimally-proportioned dry matter of whole-plant corn in a squeezing and extruding mode. The whole-plant corn is mechanically harvested and smashed at the same time, and then is subjected to squeezing dewatering; squeezed-out liquid is concentrated and then is adsorbed with loess, and drying and smashing are carried out; a product is added into a squeezed dry material and the product and the squeezed dry material are mixed evenly; extruding and pelletizing are carried out, and the mixed pellet feed is obtained. The obtained pellet feed is in a yellow green color, is clumpy and does not go mouldy; the moisture content is 7.5-12.8%, the crude protein content is 6-14%, the crude fat content is 1.2-4.7%, the crude fiber content is 43.49-63%, the crude ash content is 21-43%, the nitrite content is 3.1-15.2 mg / kg, and the density is 412-526 kg / m<3>. The nutritional value and the palatability of the pallet feed are both significantly improved, the dry matter and nutritional ingredients in the corn can be preserved in the pallet feed for the longest time, the purposes of timely harvesting, processing, storing and transporting of the feed are achieved, and the feed conversion ratio is greatly increased.

Description

technical field [0001] The invention relates to a technique for large-scale whole-plant corn harvesting and processing pellet feed for livestock breeding, in particular to a mixed pellet feed directly prepared by extruding whole-plant corn with excellent dry matter. Background technique [0002] Maize is an annual herbaceous plant of the Poaceae Maize genus. Whole plant corn includes corn stalks, leaves, flowers, and corn cobs. Generally speaking, whole plant corn is used in silage whole plant corn. Stems erect, usually unbranched, with aerial strut roots at base nodes. Leaf sheath with transverse veins; ligule membranous, blade flat and wide, linear-lanceolate, base rounded and ear-shaped, glabrous or pilose, midvein stout. The caryopsis is spherical or oblate, and the glumes and lemmas are exposed after maturity, and its size varies with different growth conditions. Monoecious different flowers, flowers and fruits in autumn. It is widely planted in tropical and temper...
