Problems solved by technology

[0005] Although tetraploid Robinia pseudoacacia has high nutritional value and huge biomass, there is currently no complete set of technology for processing feed from branches and leaves of tetraploid Robinia pseudoacacia in China, so that tetraploid Robinia pseudoacacia cannot be effectively used as feed
Mainly because there are following problems in unprocessed tetraploid black locust branches stems and leaves: 1) it is difficult to store and transport over long distances, which limits the application market scope of tetraploid black locust branches stems and leaves; 2) the utilization rate of branches stems and leaves is low , waste is serious, the reason is that unprocessed tetraploid Robinia pseudoacacia branches have hard, sharp stipules on the surface (located on both sides of the base of the compound leaf axis, because it is a metamorphosis of leaves, it is called stipules in botany) Thorn) is easy to stab the tongue of livestock, causing livestock to only eat the top small part of leaves and tender stems, making the actual utilization rate of branches, stems and leaves less than 60%, and nearly 40% of the part is abandoned and wasted by livestock; 3) using The conventional chopping method, that is, cutting the young branches and leaves into 1-3 cm pieces, cannot remove or soften the stipules, so it still cannot improve the feeding rate of the stems and leaves of tetraploid Robinia pseudoacacia branches
4) The mixed use of branches, stems and leaves reduces the feed value of tetraploid Robinia pseudoacacia leaves, because tetraploid Robinia pseudoacacia branches and stems contain lignin that is not conducive to the digestion and utilization of monogastric animals, so that tetraploid Robinia pseudoacacia leaf powder cannot be used as High-protein feed ingredients are used in compound feed for monogastric animals with a broad market, which in turn affects the economic benefits of planting tetraploid Robinia pseudoacacia

Embodiment 1

[0039] Such as figure 1 Shown, the inventive method comprises following processing steps:

[0040] 1) Raw material collection

[0041] According to the requirements of the tetraploid Robinia pseudoacacia dwarf forest management model, the stems and leaves of the tetraploid Robinia pseudoacacia branches are cut at different suitable harvesting periods in each growing season (about the end of May and the end of July each year), and the branches, stems and leaves are separated in time. Or manually separate the branches and leaves, collect the separated branches and leaves separately, and process them separately: the branches and stems are processed into soft silky materials by rubbing and other steps, and the silky materials can be fed directly or passed through After drying, it is crushed into powder; the leaves are processed by drying, crushing and other steps, as follows:

[0042] 2) Processing tetraploid black locust branches and stems into filamentous material

[0043] In o...

Embodiment 2

[0057] Steps 1) and 2) in Example 1 were used to collect the raw materials and rub the branches and stems of the tetraploid Robinia pseudoacacia.

[0058] Then knead the silk-like material to take the following method to ensile for more than 60 days: add water to the silk-like material to make the water content of the silk-like material 45% to 55%, and then in a closed container, without adding any additives Ferment at 19°C to 37°C for more than 60 days.

Embodiment 3

[0060] Steps 1) and 2) in Example 1 were used to collect the raw materials and rub the branches and stems of the tetraploid Robinia pseudoacacia.

[0061] Then, the tetraploid Robinia pseudoacacia twig and stem silk material obtained by kneading is ensiled for more than 60 days in the following way: corn stalks are mixed in the silk material, and the mixed corn stalks are crushed into 2-3cm long fragments or kneaded silk shape, and its weight ratio is: 1-4 parts of tetraploid Robinia pseudoacacia branches and stem filamentous materials, and 1 part of corn stalks.

Abstract

A process for preparing the feed or the raw material of composite feed from the stem and leaf of tetraploid locust includes such steps as separating said stems from leaves, feeding the stems in a kneading machine to obtain the soft fibrous material, and drying and pulverizing the leaves to obtain leaf powder.

Description

technical field [0001] The invention relates to a method for processing animal feed, in particular to a method for processing feed or compound feed raw materials from branches, stems and leaves of tetraploid Robinia pseudoacacia. Background technique [0002] The diploid Robinia pseudoacacia belongs to the Papilionaceae Robinia. Forage-type tetraploid Robinia pseudoacacia is bred from diploid Robinia pseudoacacia by artificially inducing somatic chromosome doubling. The area of ​​a single leaflet is 3 to 5 times that of common black locust, and the dry weight is 4 to 6 times that of common black locust. The leaves grow rapidly, are rich in nutrients, high in protein, and good in palatability, making them ideal forage trees. At present, it has been successfully cultivated in a certain area in 15 provinces including Henan, Shandong, Hebei, Gansu, Inner Mongolia, Tibet, Yunnan, and Shaanxi, and a considerable amount of biomass for feed processing has been formed every year. ...
