Embodiment 1

[0045] Embodiment 1: as attached figure 1 As shown, the whole plant corn and the whole plant alfalfa are mechanically harvested and pulverized at the same time, and then pressed and dehydrated to reduce the weight by 30-40%. The dry materials of whole plant corn and whole plant alfalfa after being squeezed are mixed and homogenized at a ratio of 1:1, and then extruded and granulated. The color of the obtained pellet feed is yellow-green, lumpy, free of mold, and has a moisture content of 9.49%. Crude protein 11%, crude fat 2.51%, crude fiber 58%, crude ash 25.23%, nitrite 13mg / kg, density 435kg / m 3 .

[0046] In the foregoing, the dried corn or stalks are pulverized and then added as auxiliary materials, mixed and homogeneously granulated. Moisture was reduced to 8.3% after granulation.

[0047] In the foregoing, the whole plant corn is harvested and chopped into 1-5 cm lengths simultaneously.

[0048] In the foregoing, no stubble is left when the whole plant corn is harve...

Embodiment 2

[0053] Embodiment 2: When the whole plant corn is harvested, the stubble is 35-53 cm. The stubble is re-harvested and used separately. The crude protein content of stubble harvested and crushed corn silage material was significantly increased, and at the same time, the indigestible fiber was significantly decreased.

[0054] In the present invention, adding crushed yellow storage or dried old corn stalks is beneficial to absorbing the moisture of the corn, so as to quickly reduce the moisture and increase the crude protein content.

[0055] In the present invention, the whole plant is harvested and crushed, the overall corn plant material is not wasted, the land is convenient for plowing, fast and efficient, the cost is reduced, the loss of nutrients is avoided, the intermediate links are reduced, and the process and production storage are greatly saved, which can effectively improve Its feed intake, organic matter digestibility, and feeding effect on dairy cows are slightly ...

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...
