Abstract

The present invention provides a method for preparing microbial fermentation stalk fodder capable of reducing the methane discharge of ruminants. The present invention adopts a common stalk processing technique of microbial fermentation. The present invention is characterized in that 0.5 to 1.5 wt% of propionic acid is added to stalks before microbial processing; micro fodder which is processed by microbial fermentation can be mixed with cotton seed cakes for further reducing the discharge of methane, and the cotton seed cakes account for 25 to 35 wt%.

Description

Preparation of microbial fermented stalk feed for reducing methane discharge of ruminant
The present invention relates to the herding feed, a kind of technology that can reduce methane discharge of ruminant effectively, handle straw feed with microbial fermentation is provided especially.
A head of cattle discharges 200~300 liters in methane every day approximately, and global ruminant every year is approximately to airborne release 65~85Tg (1Tg=10 9Ton) methane is 15~25% of global discharge of methane amount, and therefore, ruminant is the important artificial generation source of of methane.Ruminant discharging methane is relevant with their distinctive digestion methods, and methane production is relevant with feed composition and nutrient balance degree, and low-quality roughage methane generation is big.Therefore, the discharge of methane in the control ruminant stalk digestion process has the double meaning of economy and environment.Reduce the methane discharge of ruminant measure and roughly have six kinds: 1. use chemicals to reduce the cud methane-generated quantity, this method only is adapted at using in the developed country at present; 2. the element that supplements the nutrients improves rumen microorganism growth rate, but needs the extra nourishing additive agent of buying; 3. control the cud protozoa, also do not have feasible method at present; 4. use growth and performance promoter, materials such as bovine growth hormone (bST) and steroids, tachyauxesis improves the animal performance, but the influence of stocker, milk cow quality is worthy of consideration; 5. change the daily ration composition, select rumen bypass protein for use, avoid in cud, fermenting, can't resolve the methane that roughage is fermented and produced in cud; 6. handle stalk and improve digestibility, this is to be considered to the most suitable China's national situation at present, makes full use of the method for feed resource.Handle the method for stalk and generally divide Physical Processing method, chemical process method, microbe fermentation method three major types, microbe fermentation method is the emphasis direction of developmental research on straw feed at present.Patent retrieval is to several methods with microorganism fermenting compound fungus processing stalk, but none considers to reduce methane discharge of ruminant problem.
The object of the present invention is to provide a kind of production technology of microbial fermented stalk feed, its product can reduce the methane discharge of ruminant amount significantly, and production cost is not high, and the quality of the edible back of livestock meat, milk is unaffected.
The invention provides a kind of preparation of microbial fermented stalk feed for reducing methane discharge of ruminant method, adopt general microbial fermentation to handle the stalk technology, it is characterized in that: before microbiological treatment, in stalk, add the propionic acid of 0.5~1.5% weight; For further reducing discharge of methane, the littleization feed after microbial fermentation is handled can be mixed with cottonseed cake again, and the cottonseed cake proportion is 25~35% weight.
Microbial fermentation involved in the present invention is provided by " the dry straw feed biological modulated preparation of new generation " of having selected for use animal science system of Jilin Agriculture University to provide, it is by plant breast stalk bacterium, Pediococcus acidilactici, streptococcus fecalis and bulgarian milk stalk bacterium are formed, these four kinds of bacterium all are to have distinguished the microorganism that can directly feed, and belong to probiotic class probiotics, after entering animal intestines and stomach, can suppress the harmful microorganism growth, promote the beneficial microbe growth, this belongs to the dominant population theory on the action of microorganisms mode, on the microbial metabolism mode, produce lactic acid, especially newborn newborn animal is highly profitable.In general, per unit can digest feed and produce methane be subjected to two factor affecting in cud, i.e. microbial growth rate in the growing amount of propionate and the cud in the cud.The microbial growth rate in the increment of propionate in the cud and the cud of improving all can reduce the methane-generated quantity of per unit feed effectively.Selecting for use propionic acid to handle stalk at first is for keeping feed quality, do not make the loss of going mouldy, because fungus growth is bred the nutriment that will consume in the feed the easiest utilization; Next is the content that increases propionate.
If it is the propionic acid addition less than 0.5%, does not then reach mould fungus inhibition effect, also inoperative to reducing the methane generation.The propionic acid addition reaches 2~5%, littleization processing stalk, and additional cottonseed cake, making roughage can reduce below the methane to 350 kilogram, but such one is to have increased cost, the 2nd, and the butterfat percnetage of propionic acid concentration and milk has sizable relation, increases with propionic acid concentration, butterfat percnetage descends, and loses more than gain so increase propionic acid concentration.
If the content of rumen bypass protein cottonseed cake surpasses 35% weight, the free gossypol in the cottonseed cake can cause murder by poisoning to ox.If the cottonseed cake addition is less than 25%, the ox weightening finish is slow, produces that methane is also corresponding to be increased to 450~500 kilograms.
Below by embodiment in detail the present invention is described in detail.
Embodiment 1
Before the stalk micro storage, the short stalk of hand hay cutter per ton adds 1% propionic acid; " the dry straw feed biological modulated preparation of new generation " of selecting for use animal science system of Jilin Agriculture University to provide carries out the dry straw microbial fermentation and handles; The fermentation process concrete steps: 1. bacterial classification brings back to life, and every bag 8 gram of dry straw biological modulated preparation (containing viable count more than 2,000,000,000) can be handled 1 ton of dry straw (corn stalk, straw, wheat straw).Fully dissolve microbial inoculum with 400 milliliter of 1% white sugar water, placed at normal temperatures 2~3 hours, bacterial classification is brought back to life.2. loading of kiln: from kiln bottom slice feed (every layer dress crushing straw 30 cm thicks), bacterium liquid (bacterial classification after the resurrection joins and contains in 0.77% the saline solution) is sprayed in layering, the sprinkling amount makes the stalk water content reach 60~70%, and compaction in layers causes anaerobic environment to the zymophyte breeding.3. seal kiln: after the stalk compaction in layers up to exceeding 30~40 centimetres of kilneyes, fully compacting again, evenly spill salt powder (every square metre 250 gram guarantee that top do not go mouldy) at the top one deck, cover Polypropylence Sheet, spread 20~30 cm thick dry straws again, 15~20 centimetres of earthing, sealing guarantees to be anaerobic state in the kiln.Generally about 20 ℃, can finish sweat in 15 days, need 21 days about 0 ℃, finally make feed (I).Embodiment 2 feeds (I) replenish 30% rumen bypass protein, make feed (II).Be the result of actual raising ox below.Search for food and do not carry out handling the stalk of (only hand hay cutter is short), the every increase of ox body weight is produced 1200 kilograms in methane for 1 ton.The stalk of searching for food and handling through ammonification, ox is whenever put on weight 1 ton, produces methane and is lower than 700 kilograms.Search for food through the stalk of littleization processing, whenever increase 1 ton of body weight, produce 600 kilograms in methane.The feed (I) of searching for food whenever increases 1 ton of body weight, produces methane and is lower than 500 kilograms.The feed (II) of searching for food, methane-generated quantity can be reduced to below 400 kilograms.
