A kind of meat rabbit feed and preparation method
Technical field
The present invention relates to the field of fodder of particular animals, be specifically related to feed of a kind of meat rabbit and preparation method thereof.
Background technology
Rabbit meat not only has higher nutritive value, and its fiber is delicate, and the processing back is prone to absorbed by human consumption, is old man, patient, pregnant woman and child's good nutrition food.In addition, often eat rabbit body body and be difficult for getting fat, can keep the figure attractive in appearance, also have health-care efficacy,, hypertension atherosis for prevention of arterial and heart disease etc. have positive role.Therefore, be called " vigorous and graceful meat ", " beauty treatment meat ", be loved by the people by some countries of west.
Rabbit keeping is an emerging aquaculture, is the important component part of modern animal husbandry.Rabbit by its economic use difference can be divided into meat, skin with and hair use three major types.And meat rabbit in the starting of China the earliest, and mass foundation is also extensive.Especially in more northern provinces and cities and provinces such as southern Guangdong and Sichuan, meat rabbit raising development in recent years is very fast, has become some areas, particularly the pillar industry of some poverty-stricken areas.Greatly develop the meat rabbit animal husbandry, be fit to China's national situation, it has a high potential, and is of far-reaching significance.The meat rabbit daily ration is main with grass, is that the herbvore domestic animal rabbit of typical grain-saving type belongs to the herbvore domestic animal of simple stomach, and in the family of rabbit, the crude feed tolerance ability of meat rabbit is the strongest.
According to statistics, the ratio of raw grain is on average a little more than 20% in the meat rabbit feed formula, and livestock and fowl are about 60%; That is to say; Meat rabbit has higher digestive utilization ratio to the cellulose in stalk and the forage grass, and this is nervous relatively for grain, China that forage grass resource is abundant; Greatly develop the meat rabbit animal husbandry, be of great immediate significance.
The total energy that occurs on feed ingredient and the nutritive value table, digestible energy etc. are the indexs of representing fodder energy; Be digestible energy (Digestible Energy; Be abbreviated as DE) be the contained energy of feed digestible nutrient, promptly animal take in feed can be with fecal energy poor.That is: DE=GE – FE.
(1) total energy: the summation that is meant contained heat energy in carbohydrate in the feed, crude fat and the crude protein.Study mensuration through forefathers, the energy that starch contains is per kilogram 17.57 million Jiao, and fat is per kilogram 39.33 million Jiao, and protein is per kilogram 23.85 million Jiao.As dried wild grass can be per kilogram 15.73 million Jiao, wheat bran is per kilogram 16.28 million Jiao, rice bran is 16.53 million Jiao, the corn per kilogram is 16.6 million Jiao, the soybean per kilogram is 17.11 million Jiao etc.Total energy in the feed can not all be digested and assimilated by poultry, fowl.For example, starch is made up of glucose, and cellulose also is made up of glucose, and therefore, their energy all almost is per kilogram 17.57 million Jiao, on calorimeter, measures.But because their structure is different, ruminant can digestibility and utilization part cellulose, and non-ruminant animal just can not utilize well.The total energy of corn and corn stalk is close for another example, but corn can be Duoed 7 times than corn stalk by the energy of livestock digestibility and utilization.Therefore, total energy can only be explained the energy that feed itself is had, and can not reflect the energy that poultry, fowl obtain from feed.
(2) digestible energy: be exactly the energy that contains in the feed digestible substance, the part of just removing the energy that the material that can not digest contains in the feed total energy is an ability in the excrement.Ability in feed digestible energy=feed total energy-excrement.Various poultrys, fowl and various different growth phase thereof, digestion power is different, so same feed has different digestible energies.
We know that mostly animal feeding-stuff material composition is vegetal cereals, oilseeds class, piece root crop, and a lot of plant feeds all contain some can make feed nutritive value reduce; Growth of animals or poultry is slowed down, the material that feed conversion rate reduces, the for example saponin in cellulose, enzyme inhibitor, the alfalfa meal etc.; How to overcome the influence that these materials that are unfavorable for animal digestion bring, the plant feed and the material that digests that is unfavorable for that wherein contains are controlled at suitable ratio, can give full play to the energy in the feed; And reduce the influence of unfavorable material as far as possible, thus improve the digestible energy of feed, also promptly improve the conversion ratio of material; Realization further improves the feed formula of meat rabbit, improves the conversion ratio of feed, at utmost reduces the consumption of grain; Optimize feed formula; Make efficiency of feed utilization high, the meat rabbit growing way is good, resistance against diseases is strong, and the culturing economic benefit is good; Cost solution for raising enterprise is significant, also has significant impetus for the Feed Manufacturing enterprise raising product quality and the market competitiveness.
Summary of the invention
For solving the problem that exists in the background technology, overcome the influence that these materials that are unfavorable for animal digestion bring, further optimize the prescription of meat rabbit feed; Improve the conversion ratio of feed; Reduce the consumption of grain, the present invention aims to provide a kind of meat rabbit feed and preparation method thereof, and this meat rabbit feed has the efficiency of feed utilization height; The meat rabbit growing way is good, resistance against diseases is strong, the advantage that the culturing economic benefit is good.
For realizing above-mentioned purpose; The present invention has adopted following technological means: a kind of meat rabbit feed; It is characterized in that, comprise the raw material of following percetage by weight: corn 20-30%, dregs of beans 16-24%, wheat bran 15-20%, broad bean chaff 20-30%, sweet potato chaff 8-12%, stone flour 1-1.8%, salt 0.4-0.7%, premix 1-1.8%.
A kind of meat rabbit feed, preferred proportioning is: corn 24%, dregs of beans 20%, wheat bran 16.5%, broad bean chaff 25%, sweet potato chaff 11%, stone flour 1.5%, salt 0.5%, premix 1.5%.
Added the corn of 20-30% and the dregs of beans of 16-24% among the present invention, its reason is: contain protein enzyme inhibitor and amylase inhibitor in the corn, and legume crop be generally acknowledge contain the more grain of amino acid; Protein enzyme inhibitor and amylase inhibitor easily separately or mutually combine and form the very slow compound of speed that dissociates can cause not digesting the accumulation of nutrients in enteron aisle, reduce the concentration of digestion product in enteron aisle and the blood; Thereby influence the secretion of enteron aisle hormone, reduce the absorption of enteron aisle to nutritional labeling in the feed, the several amino acids that dregs of beans includes is fit to the demand of livestock to nutrition; Amino acid helps the decomposition of this compound; Inhibitory action that can their digestion of all or part of counteracting, just for these reasons, the addition with corn among the present invention is limited to lower level; The amylase inhibitor in the minimizing corn and the total amount of protein enzyme inhibitor; Add dregs of beans simultaneously,, reduce the influence of unfavorable material to improve content of amino acids in the feed; Thereby improve the digestible energy of feed, also promptly improve the conversion ratio of feed.
Added the wheat bran of 15-20%, the broad bean chaff of 20-30% and the sweet potato chaff of 8-12% among the present invention, also added the stone flour of 1-1.8% simultaneously, its reason is: wheat bran and broad bean chaff are used more extensive as crude fibre commonly used in the feed; But meat rabbit is a nonruminant, and when the crude fibre in the feed was too much, not only crude fibre can not be digested and absorbed effectively; Also can influence the absorption to other nutriment, data shows: crude fiber content increases by 1% in the feed, and protein digestibility just reduces by 0.3%; The organic substance digestibility reduces 2%-8%; And the absorption of mineral matter can effectively solve the negative effect of crude fibre to feed digestion, and for these reasons, the present invention has added a part of stone flour in feed; Be used for replenishing mineral matter; Reach the influence that reduces unfavorable material, thereby improve the digestible energy of feed, also promptly improve the purpose of the conversion ratio of feed; Simultaneously, the sweet potato good palatability, nutritious; The content of its crude protein and lysine etc. surpasses wheat bran, rice bran etc.; In feed, adding the sweet potato chaff can partly replace wheat bran etc., plays the balanced nutrients proportioning, reduces cost; The nervous contradiction of raw material in the link Feed Manufacturing enterprise can also be replenished protein simultaneously to reduce the consumption of fish meal, soya-bean cake.
Added an amount of salt among the present invention; Salt plays important regulatory role on the physiology of livestock; Content is more in blood, gastric juice and other body fluid, has the growth of promotion, helps the effect of regulating pH value of body and keeping osmotic pressure balance between cell and blood.Chlorine in the salt can generate the hydrochloric acid in the gastric juice, keeps the acidity in the stomach, the sodium in the salt, and the alkalescence of maintenance digestive juice helps the activity of digestive ferment in enteron aisle.
Premix is the abbreviation of additive premix; It is with one or more microcomponents (comprising additives such as various trace quantity mineral substance elements, various vitamin, synthesizing amino acid, some drugs) and diluent or carrier proportioning on request, the osculant compound feed products of processing after evenly mixing.
The preparation method of above-mentioned meat rabbit feed is following:
1., iblet is in the natural conditions fermentation down of water logging bubble, with reduction protein enzyme inhibitor and amylase inhibitor content wherein, wears into even thickness, sizeable powder after the drying;
2., after dregs of beans, wheat bran, broad bean chaff, sweet potato chaff add the cellulose enzyme processing, pulverize levigate respectively on request;
3., above-mentioned raw materials is mixed, add stone flour and salt, mixture homogeneity≤7% during;
4., mixed raw materials is granulated, pelleting temperature 78-82 ℃, the grain diameter that makes is Φ 4.0mm-Φ 6.0mm;
5., with pellet be cooled to divide behind the normal temperature grade packaged.
The present invention has following beneficial effect:
A, the present invention develop the meat rabbit feed of reasonable mixture ratio between each nutrient according to the growth characteristics of meat rabbit and the mutual restriction and the influence of the various raw materials of feed, effectively overcome the influence that the material that is unfavorable for animal digestion in the feedstuff brings; The plant feed and the material that digests that is unfavorable for that wherein contains are controlled at suitable ratio, can give full play to the energy in the feed, and reduce the influence of unfavorable material as far as possible; Thereby improve the digestible energy of feed, also promptly improve the conversion ratio of material, realize the feed formula of meat rabbit is further improved; Improve the conversion ratio of feed; At utmost reduce the consumption of grain, optimize feed formula, make efficiency of feed utilization high; The meat rabbit growing way is good, resistance against diseases is strong; The culturing economic benefit is good, and is significant for the cost solution of raising enterprise, also has significant impetus for the Feed Manufacturing enterprise raising product quality and the market competitiveness.
