Description
Technical field
The invention belongs to agricultural science and technology class herding scientific domains, and in particular to a method of regulation and control mutton sheep modification fattening.
Background technology
Mutton fat content is relatively low, and protein content is between pork and beef, calcium, iron, phosphorus and copper, zinc etc.
Rich content often eats mutton, has important health-care effect.The gradually heating of mutton consumption at present, promotes sheep husbandry by herding
Area is extended to agriculture district, southern area.It is influenced by traditional cultivation theory and fast well-fattened pattern, at present in agriculture district stable breeding and scale
Change the mutton produced in farm, with the problems such as smell of mutton weight, dressing percentage is low and meat is older, poor taste, due to mutton product
Matter differs greatly, and causes the fluctuation of market comsupton, affects the orderly development in mutton market, greatly limits carrying for mutton consumption
It rises.Therefore change tradition fattening at present and fast well-fattened pattern, Mode change is fattened in the modification regulated and controled to meat, is to stablize mutton
Quality expands the important technology demand of mutton consumption.
Mutton sheep economic benefit higher through modification fattening.Under the conditions of tradition fattening, the feed resource of mutton sheep can not carry out section
Learn allotment so that food utilization efficiency is not high, and economic benefit is not notable.Mutton sheep reaches under the conditions of tradition fattening delivers body for sale accordingly
Weight, needs 1 year or more time, causes meat aging, mouthfeel is poor, and mutton selling price is relatively low.For being slaughtered under traditional aquaculture model
The lamb of government official delivers weight for sale so that dressing percentage is low, and dressing percentage is low, limits sheep raising economic benefit accordingly due to not reaching.
The high bed occurred in recent years cultivates fast well-fattened pattern, mainly copes with current mutton supply deficiency, and breeding cycle length is asked
Topic, good result is achieved in terms of improving Mutton yield.Be easy to cause during traditional agent for rearing and fattening meat sheep fatty over-deposit or
The problems such as fat shortcoming so that quality of mutton declines, therefore traditional aquaculture model and the quick aquaculture model of high bed are all to surround sheep
The low-end market of meat competes, the problem of not accounting for quality-improving, the high added value in later stage.And it modifies fattening technology and aims to solve the problem that
Livestock products in aquaculture differ greatly so that deliver mutton sheep homogenizing, is superior from weight to meat, orientation regulation and control meat for sale
The nutrient distribution of sheep, to efficiently produce high-quality mutton, to stablize the consumption confidence of customer and meet the city of mutton consumption
Field demand.
Modification fattening can integrally improve the quality for delivering mutton sheep for sale, improve quality of mutton.The drawbacks of traditional fattening pattern is
It delivers mutton sheep for sale and overfertilization or excessively thin occurs, overfertilization then has that fat deposition is excessive, due to the difference at fat deposition position, exploitation value
Value differs greatly.The mutton sheep of overfertilization, fat are mainly deposited on tail portion and internal organ, and practical value is smaller.Cross thin mutton sheep, dressing percentage
Low, mouthfeel is relatively poor, but pass through modification fattening also can further increase the quality of mutton on the basis of fast well-fattened,
The ratio of non-edible partial fat is reduced simultaneously.
Southern region of China has formd the fattening pattern of high bed cultivation at present, and traditional free-range mode is transformed into collection
Reduction is fattened, and the efficiency and level delivered for sale are substantially increased.But the change of aquaculture model, quality of mutton is brought certain
It influences, needs to explore corresponding feeding management and nutrition regulation technology to keep and improve the quality of mutton.Sheep is as China
High-quality indigenous kind, have the good characteristics of resistance to drylot feeding, the first choice having become under scale fattening pattern is maternal.Utilize lake
Sheep is fattened as the offspring that female parent is hybridized can obtain good resistance to drylot feeding performance, and obtain good production
Benefit.Relevant research is had been carried out for the growth-development law of sheep and filial generation at present, finds 6 monthly ages or so lamb
Sheep lists through fattening, and benefit is more notable.But since the speed of growth is very fast, the flavor and taste of corresponding mutton have certain journey
The reduction of degree.
Invention content
By corresponding nutrition regulation technology, the fixed direction allocation of nutriment may be implemented, reach the mesh of meat regulation and control
, under China's drylot feeding mutton sheep pattern, quality of mutton is generally reduced the present invention thus, is designed the meat sheep modification of regulation and control and is educated
The method of fertilizer, to improve the quality, mouthfeel and benefit of mutton.The method being combined with feeding management using nutrition regulation, in meat
Sheep fattens the interim adjustment of period progress, to obtain expected meat.

Specific implementation mode
Below by way of specific embodiment, invention is further described in detail.
On the basis of synthesis existing mutton sheep production system, be dedicated to improving and deliver mutton sheep for sale and homogenize and meat, for batch
The high-grade meat of amount production provides technological reserve, is the technology original intention of the present invention.For from select sheep to fattening deliver for sale in all too many levels
Critical issue is mainly solved in the following manner.
(1) cause Fattening Sheep to deliver the uniformity for sale under the control tradition fattening pattern of fattening lamb regularity poor, mainly by
In the kind of fattening lamb and monthly age there are larger difference, the quality discrepancy for delivering mutton sheep for sale is caused.The present invention focuses on the product of lamb
The consistency of kind consistency, fattening starting monthly age or weight provides premise for the globality regulation and control in later stage and the production that homogenizes
Condition.
(2) production of the public affairs that dock prime lamb, which changes not dock in Conventional process, carries out the wrong theory of fattening production, system
One is produced using the public lamb of docking.Since the tail portion of mutton sheep has stronger fat deposition ability, fattened under the conditions of not docking,
Cause body fat preferential deposition in tail portion, and tail portion fat edible value is not high.Under the conditions of science is fattened, the public lamb in August age, body
85% or more of adult weight level is nearly reached again, but sexal maturity not yet significantly affects its meat flavor, therefore
Modification fattening is carried out using the public lamb of docking, has not only maintained its faster speed of growth, but also maintain ideal meat flavor.
(3) under the traditional agent for rearing and fattening meat sheep pattern of interim regulation and control, the unilateral speed of growth for focusing on mutton sheep regulates and controls skill to stage
Art and corresponding management measure do not reach fining level.The present invention carries out interim battalion from mutton sheep tissue development rule
Regulation and control are supported, the orientation regulation and control of nutrient distribution are carried out in the fattening later stage, it is final to realize mutton sheep modification fattening.
(4) in mutton sheep growth course, the proliferation of 3-5 monthly age adipocytes has been started up for the startup of lipocyte proliferation,
This phase needs certain propionic acid content to carry out stimulation growth.The development weight in the stage is not paid attention in traditional mutton sheep production process
Point causes loose two of lipocyte proliferation early period slow and later stage adipocyte hyper-proliferative extreme, this is all unfavorable for meat
The regulation and control of matter, in addition due to fat deposition it is excessively slow, it is too fast caused by so that intramuscular fat is not deposited accordingly, therefore
Quality of mutton and flavor are adversely affected.The present invention is that the proliferative induction of adipocyte is carried out to of the right age lamb, and use is low
Intensity, prolonged induction mode are ready for the fat deposition in later stage.
(5) under the traditional fattening pattern of modified fattening, fat deposition is too fast or excessively slow, causes the excessive and intramuscular fat of fat lump
Fat deposition is insufficient, greatly limits quality of mutton and flavor.The present invention has found in the course of the research, in the 6-8 ages month of fattening
Between, using fat content and orientation two kinds of technological means of regulation and control is improved, promotes the deposition of intramuscular fat, be aided with production management control
System so that the lamb of production is substantially improved in terms of color and luster, mouthfeel.
In implementation process of the present invention, mainly implemented by following link, to ensure corresponding effect.
1, column home cleaning and disinfection carry out cleaning up excrement, disinfection, corresponding column home, hopper for the place to be fattened and equipment
It is reinforced, is prepared for fattening, it is ensured that the health of mutton sheep during fattening.
2, the selection of public lamb is fattened since the present invention is more demanding to the regularity of lamb, it is therefore proposed that bright using source
Really, kind is consistent, of the right age docking public affairs lamb of health is fattened, and is advisable with 13-16kg, for some early growth situations
Poor lamb, it is proposed that divide group according to the weight principle of correspondence, for the good lamb of growth conditions, it is proposed that similar in age in days
Principle divides group.After lamb divides group, earmarking, while feeding a small amount of roughage.
3, the living environment after dividing group and nursing that the lamb adaptation for dividing group is divided to group 3 days, carries out corresponding expelling parasite operation, selects
With ivermectin, operated with reference to specification.After expelling parasite 5 days, digestive powder is added, is added to daily ration according to 0.2% ratio
Middle progress stomach invigorating processing, continuous addition 7 days, prepares for the fattening in later stage.
4, it raises and manages fattening and be divided into three phases, 3-4 stages at monthly age, 5-6 stages at monthly age, 7-9 stages at monthly age, educating
In the first two stage (i.e. 3-4 stages at monthly age, 5-6 stages at monthly age) of fertilizer, lamb is by the way of free water, the third rank of fattening
Section (7-9 stages at monthly age) limits lamb drinking-water in 2 hours after feeding.During entire fattening, vaccine is carried out according to normal procedure
Injection.Management aspect, column home carry out cold-proof cooling measure.The regular cleaning up excrement of entire fattening period pays attention to patrolling column observation, Scientific epidemics prevention.
Yard feeding pattern, which uses, feeds twice day, the mode of equivalent feeding.In terms of the selection of roughage, soya bean stem meal, clover, complete stool ensiling are used
One or more in corn, hay, peanut vine, whole process tries not to exchange roughage, when exchanging feed, needs 10 days or so
Transitional period.
5, fattening stage details of operation is specifically modified
Select Du lake public affairs lamb (or 2-3 monthly ages) of 12-15kg weight, it is ensured that health, build is normal, carries out corresponding
Fattening.It is as follows to fatten program：
The 3-4 monthly ages are this growth period speed of the fast growing period of fattening, mainly with muscle deposition and bone growth
Based on, the protein content in fine fodder suitably increases, and crude protein is advisable with 12.5-14% in daily ration, and essence is slightly than control 60:40
In range.To prevent the urethral calculus in fattening later stage, calcium phosphorus ration to be maintained at (1.5-2.0):1, calcium 0.50- in daily ration
0.55%, phosphorus 0.25-0.30%.Vitamin A 4000IU/kg, vitamin D 3700IU/kg.Day is fed according to the 3% of weight
Grain adjusted every 10 days and increased 50-70 grams/.Roughage is green with crushing beanstalk, the full boiled corn being easy to get in the localities
Based on storage, adds water to mix thoroughly with fine fodder before feeding, be evenly distributed to flock of sheep.Free water.
The 5-6 monthly ages are 5 monthly age of adipocyte induction period lamb, and under the conditions of high fine fodder daily ration, adipocyte starts to be proliferated,
Adipocyte count starts to increase, but adipocyte volume increases, and has the ability of deposition fat, but with cell number
Based on proliferation.This phase slightly compares 70 by further increasing daily ration essence:30, propionic acid yield in cud is increased (when the thick ratio of daily ration essence
Example reaches 7:When 3, fermentation pattern is propionic acid type fermentation in cud, can increase the yield of propionic acid), while increasing scale of feeding so that
Feed intake accounts for the 3.0%-3.2% of weight, Dietary Crude Protein Levels 11-13%.Every 10 days, every mutton sheep increased 50-
70 grams of feed intakes.Calcium phosphorus ration is maintained at (1.5-2.0):1, calcium 0.60-0.80%, phosphorus 0.35-0.45% in daily ration.Vitamin
A 4000IU/kg, vitamin D 3500IU/kg.Roughage adds water to mix thoroughly, uniformly before feeding to crush based on beanstalk with fine fodder
It is assigned to flock of sheep, free water.
The 7-9 monthly ages be modification this phase of regulation and control phase be early period muscle, bone growth on the basis of, the proliferation of adipocyte and
Growth is started, and the orientation regulation and control of fat deposition are carried out.Energy feed uses barley, the ratio in fine fodder to reach 60-
70%.This stage uses 80:20 daily ration, the 2.8%-3.0% of feed intake percentage of liveweight add fatty acid calcium 4.0-6.0%, mistake
Cud choline 0.1-0.3%, sodium bicarbonate 0.7%.This phase crude protein level is maintained at 8.0-11.0%, and energy concentration control exists
8.4kJ/kg is hereinafter, calcium, phosphorus level are kept at 0.7% and 0.3%.Vitamin A (VA) 3500IU/kg, vitamin C (VC)
170mg/kg, vitamin E (VE) 420IU/kg.Moisture in suitable control daily ration is advisable with being maintained within 40%.After feeding
In 2 hours, water restriction, free water later.
During mutton sheep modifies and fattens, in addition to the drinking-water time of modification fattening stage is controlled, other stages
It does not drink water the control of time.During entire fattening, salt is controlled 0.5%, and coban moderately adds in premix,
The adding proportion of premix is 4%.During preparing daily ration, the preferred selection order of protein feed raw material is cotton dregs>Dish
The dregs of rice>Dregs of beans can also be that multiple protein raw material carries out mix and match, and coarse fodder is green with common beanstalk, peanut vine, whole-plant corn
Based on storage, dry wheat straw, straw, it may be selected one such or a variety of.In entire fattening period, using slatted floor yard feeding pattern, 1
Cleaning up excrement is primary within a month.
It is uniformly delivered for sale after can reaching fattening time in principle, due to feeding and management level and the difference of animal individual,
The pattern delivered for sale in batches may be used.Weight is delivered for sale when reaching 40kg or more to be advisable, and it is heavy can to obtain convenient fat at this time
Product and meat.
Case study on implementation：
