Description
Technical field
The invention belongs to feed stripped technical field more particularly to a kind of feed improving mutton sheep growth performance and its preparations
Method.
Background technology
Changing with consumption idea as China's Living consumption is improved, mutton is more and more favored by consumers, by
Gradually it is changed into the consumer goods perennial, for the entire people, mutton demand continues to increase.China is the maximum mutton country of consumption in the whole world, per capita
Consumption figure is more than 3kg, and mutton consumption accounts for the 5% of entire consumption of meat proportion.China's Mutton yield, sheep breeding stock and the amount of delivering for sale
It occupies first place in the world, however annual China needs about 50,000 tons of mutton of import that could meet domestic market mutton demand.Therefore, it improves
Domestic mutton production amount shoulders heavy responsibilities.
Feed is the material base of mutton sheep cultivation, and quantity, product quality and the economic benefits of mutton sheep production are largely
Depending on the progress of feed technology and the popularization and application of new technology.Roughage is the important component of meat sheep feed, roughage it is excellent
The bad practical effect for being largely fixed feed, and mutton sheep culturing high-quality roughage resource still lacks relatively at present
Weary, existing mutton sheep roughage generally existing feeding mutton sheep weightening is slow, the high problem of feed-weight ratio.Quinoa stalk is rich in a variety of battalion
Substance is supported, quality is hard, after mutton sheep feeding, promotes cud development, increases mutton sheep and ruminate number, can be effectively improved nutrient and disappear
Rate.
Invention content
In view of this, the purpose of the present invention is to provide a kind of weightenings of mutton sheep, improvement mutton sheep fast, that daily ingestion amount is high grows
Feed of performance and preparation method thereof.
In order to achieve the above-mentioned object of the invention, the present invention provides following technical scheme：A kind of feeding improving mutton sheep growth performance

Embodiment 4
Experiment 40 genetic backgrounds of selection are identical, the disease-free, upgrowth situation of health is good, or so 3 monthly ages weight close (28.7
± 1.2kg) the public lamb of sheep wean, be divided into 4 groups by body weight uniformity principle, every group of 10 repetitions each repeat 1 sheep.Examination
It tests and arranges transitional period 14d, preliminary trial period 10d, positive to try phase 60d, the transitional period is with feeding basal diet during pre-feeding period (in comparative example 1
Feed).The positive examination phase claims lamb weight on an empty stomach for continuous two days before starting, and carries out homogeneity test, original body mass is poor between ensureing each group
It is different not notable.
Experimental basis diet (feed in comparative example 1) formula is with reference to People's Republic of China's agricultural industry mutton sheep raising mark
Accurate (NY/T816-2004) is prepared by the Fattening Sheep nutritional requirements of weight 30kg, daily gain 250g/d.When recipe calculation, raise
Expect that the content of dry matter (DM) in raw material, thick protein (CP), neutral detergent fiber (NDF), calcium (Ca) and phosphorus (P) uses actual measurement
Value, other indexs are with reference to Chinese feed ingredient and nutritive value table (the 26th edition).It is mixed through being sufficiently stirred after feedstuff crushes
It closes, pellet is pressed into using granulating process, pelleting temperature is 70 DEG C, a diameter of 6mm, and length is 10~15mm, natural wind
It is dry for use.
It tests sheep and uses separated raising, repeat the influence that the arrangement of sheep only considers position effect, each list column is equipped with independent
Hopper and breaker, be freely eaten and drinking-water, clean bucket daily, ensure sufficient, clean drinking-water.Test sheep day feeding 4
It is secondary, respectively at 6:30、11:30、15:30 and 19:30 carry out, the daily inventory of accurate recording and surplus doses.Before on-test, institute
There is experiment sheep to inject aftosa vaccine, sheep pox vaccine and sheep tetrad three proofings vaccine and expelling parasite, to every experiment within the transitional period
Sheep takes orally 5~10mg albendazoles, and 0.6% metrifonate dipping Efficacy animal vermin is used in combination.Weekly with 1:3000
II (main component of strength Anaprox：Sodium dichloroisocyanuratepowder powder) it carries out disinfection processing to experiment sheep hurdle, including sheep pen, expect
Bucket, bucket, hopper, ground, wall and other tools.Periodic cleaning sheep hurdle excrement keeps the sanitation and hygiene inside and outside sheep hurdle.
The original body mass of record experiment sheep, the last weight of experiment, average daily gain, average daily gain, and feed-weight ratio is calculated, it ties
Fruit is shown in Table 5.
By table 5 as it can be seen that compared with control group (comparative example 1), with the raising of daily ration quinoa stalk pitch-based sphere, sheep is tested
Body weight gains and average daily gain have an increase, and 16% quinoa stalk addition group (embodiment 2) average daily gain is significantly higher than pair
According to group (P<0.05), and when daily ration quinoa stalk level is increased to 24% (embodiment 3), experiment sheep end weight and average daily gain
Have compared with 16% group of significant decrease (P<0.05) it, and with control group is on close level (P>0.05).Daily ration, which adds quinoa stalk, to be improved
Experiment sheep feed-weight ratio, and 16% quinoa stalk group feed-weight ratio is substantially less than control group and 24% group of (P<0.05).
Influence of the 5 daily ration different level quinoa stalk of table to Lamb performance
Note：Different disposal group data shoulder mark difference lowercase letter indication difference significantly (P<0.05) same letter or not, is marked
Mark indicates difference not significantly (P>0.05)；SEM is average of samples standard error.
By above-described embodiment it is found that the feed provided by the invention for being effectively improved mutton sheep growth performance, the present invention pass through by
The quinoa stalk and maize straw, corn, molasses, Soybean Meal, rapeseed dregs and concentrate feed carry out compounding and obtain feed in proportion,
Full of nutrition, feeding mutton sheep weightening is fast, feed intake is high, feed-weight ratio is low.It is recorded according to embodiment, the feeding of 16% quinoa stalk addition
The digestible energy of material is 12.0MJ/kg, and crude protein mass percentage is 16.4%, neutral detergent fiber 31.11%, and starch is
33.58%, calcium 0.60%, phosphorus 0.30%；Average daily gain is significantly higher than control group (P<0.05), feed-weight ratio is substantially less than
Control group (P<0.05).
The above is only a preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, various improvements and modifications may be made without departing from the principle of the present invention, these improvements and modifications are also answered
It is considered as protection scope of the present invention.
