Description

Utilize alfalfa processing composite granular feedstuff and preparation method thereof

Technical field

The present invention relates to forage grass processing technique field, particularly relates to a kind of with composite granular feedstuff and preparation method thereof that alfalfa is primary raw material preparation processing.

Background technology

Alfalfa has the title of " King of Pasture ", prominent advantage to be, and 1. grass yield is high.Excursion is very big because growth year is different with natural conditions for the grass yield of alfalfa, and after broadcasting, every mu of green forage yield of 2～5 years is typically at 2000～4000 kilograms, hay yield 500～800 kilograms.Radix Glycyrrhizae 733～800 kilograms can be produced the most regional every mu of hydrothermal condition；The area of arid low temperature, every per mu yield Radix Glycyrrhizae 400～730 kilograms；The irrigated area of Desert Oasis, every per mu yield Radix Glycyrrhizae 800～1000 kilograms.2. utilization periods is long.The alfalfa life-span up to 30 years as long as, field cultivation utilization periods up to about 7～10 years.But its yield, is entering high yield after date, is declining with the increase at age.3. reproducibility is strong, resistance to cradles.Alfalfa reproducibility is very strong, can quickly recover life, within general 1 year, can cradle 2～4 times after cradling, and many persons can cradle 5～6 times.Herbaceous stem is good, palatability is strong.The tender deliciousness of alfalfa stem and leaf, no matter green grass or young crops is raised, ensiling, modulation green hay, processing grass meal, for mixed feed or mixed fodder, all kinds of poultry eating, is also to raise pigs and aviculture first-selection greenfeed.The most nutritious.Alfalfa stem and leaf contains content in rich in protein, mineral, multivitamin and carotene, particularly blade higher.During the fresh and tender state of alfalfa, leaf weight accounts for about the 50% of Herb, and in blade, gross protein value is higher 1～1.5 times than stem stalk, crude fiber content fewer than stem stalk more than half.On the soil of same homalographic, total nutriment that digests of alfalfa is 2 times of graminous pasture, and digestible protein is 2.5 times, and mineral is 6 times.

Existing pellet feeds from stalks is by harvested for crops straw, by mechanical activation comminution or rub broken rear briquetting and form, cellulose in straw, hemicellulose, the mosaic texture of lignin there is certain destruction, nutritive value is very limited, lack ruminant domestic animal at nutrient necessary to each growth stage, palatability is poor, the most fully improves the utilization rate of alfalfa forage grass raw material.

Summary of the invention

It is an object of the invention to, with the composite granular feedstuff that alfalfa is primary raw material preparation processing, solve the low problem of alfalfa forage grass utilization rate, alfalfa is passed through processed, it is provided that a kind of be of high nutritive value, the full price composite granular feedstuff of good palatability.

The technical problem to be solved is realized by techniques below approach:

One of the present invention utilizes alfalfa to process composite granular feedstuff, mainly comprises the following raw materials by weight percent:

Alfalfa juice powder 40～70%, wheat stalk powder 15～30%, enzyme preparation 0.3～1.5%, vitamin 2～10%, bean cake 2～8%, fish flour 1～5%, limestone 1～5%, carbamide 1～5%.

It is preferably: alfalfa juice powder 65%, wheat stalk powder 15%, enzyme preparation 0.5%, vitamin 4.5%, bean cake 6%, fish flour 5%, limestone 2%, carbamide 2%.

The composite granular feedstuff that the present invention utilizes alfalfa to process also can contain 1～2wt% molasses.

Described enzyme preparation is made up of cellulase and hemicellulase, and vitamin is containing VitAVitE, vitamin D and trace element (Fe, Cu, Mn, Zn, I etc.).Finished product is bought on bean cake, fish flour, limestone, carbamide market.

Another technical problem to be solved by this invention is to provide a kind of preparation method utilizing alfalfa composite granular feedstuff.

The preparation method of composite granular feedstuff of the present invention, step is as follows:

1) the fresh and tender alfalfa grass that will cradle, the most uniformly mix with the wheat stalk of new results, rupture through repeatedly rolling to stem stalk, Herba Medicaginis rolls out juice and sucks in wheat straw waste, make fresh and tender alfalfa mix storage with after wheat straw waste natural drying, be processed into the grass meal that alfalfa mixes with wheat stalk.

2) mix homogeneously with each raw material by following percentage by weight:

Alfalfa juice powder 40～70%, wheat stalk powder 15～30%, enzyme preparation 0.3～1.5%, vitamin 2～10%, bean cake 2～8%, fish flour 1～5%, limestone 1～5%, carbamide 1～5%, molasses 0.5～2%；

3) by step 2) moisture of gained mixture is adjusted to 20～30wt%, stands overnight,

4) mixture after overnight is processed into pellet and be get final product.

The beneficial effects of the present invention is and utilizing alfalfa processing composite granular feedstuff is complete feed, containing Livestock in nutritional labeling necessary to each growth stage, can partly substitute concentrate, replacing whole Radix Glycyrrhizae, there are strong paste fragrance and mouthfeel sugariness, feed intake and the grazing speed of Livestock can be improved, improve culture benefit.

[test example 1] present invention utilizes alfalfa processing composite granular feedstuff to feed the effect test of Fattening Sheep

One, materials and methods

This experiment was carried out in sincerity garden, Longxi County, Gansu agriculture and animal husbandry exploitation farmer specialized cooperative society Fattening Sheep group from March, 2013 to April, was only all from, for examination sheep, the mutton sheep that mountain area is eliminated, and age, body size are basically identical.Before experiment two groups of sheep are all carried out cropping, dipping, anthelmintic, stomach invigorating, immunization inocultation, numbering, earmarking, weighs, register.Colony house implement identical, disinfect.

According to registration, the sheep participating in test is only hived off at random, experimental group 30, matched group 30, separately colony house, raise.The composite granular feedstuff of test group alfalfa processing feeds, and the matched group feedstuff of the daily autogamy of raiser and straw forage are fed, and freely drink waters, and test group and matched group sheep all use stable breeding, every bu morning, late twice.Test period is preliminary trial period (7d) and is just trying the phase (30d), at the end of, carry out test group and matched group morning weighing on an empty stomach.

Two, Experimental Comparison result

The average starting weight of matched group is 34.32kg+5.26kg, average end is heavily 38.07kg+5.159kg average weight gain 3.75kg, average daily gain 123.9g+30.22g, test group is the most heavily 36.6kg+5.86kg, average weight gain 4.98.kg, average daily gain 16.50g+71.3g.Test group 41.1g more than matched group daily gain.

Three, result and analysis

By to the effect test utilizing alfalfa processing composite granular feedstuff to feed Fattening Sheep, illustrate that alfalfa processing composite granular feedstuff has obvious effect to Fattening Sheep weightening finish, on the one hand the time that Fattening Sheep is searched for food is reduced, Fattening Sheep minimizing activity, consume one's strength, on the other hand explanation utilizes alfalfa processing composite granular feedstuff nutrition arrangement reasonable, also reduces the consumption of a large amount of forage grass, has significant economic benefit.
