A kind of meat rabbit feed and preparation method
Technical field
The field of fodder that the present invention relates to particular animals, is specifically related to feed of a kind of Meat Rabbits and preparation method thereof.
Background technology
Rabbit meat not only has higher nutritive value, and its fiber is delicate, easily digested after processing, 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 figure attractive in appearance, also have health-care efficacy,, hypertension atherosis for prevention of arterial and heart disease etc. have positive role.Therefore, by some countries of west, be called " vigorous and graceful meat ", " beauty treatment meat ", be loved by the people.
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 three major types.And meat rabbit in the starting of China the earliest, mass foundation is also extensive.Especially in provinces such as more northern provinces and cities and southern Guangdong and Sichuan, meat rabbit raising in recent years development is very fast, has become some areas, particularly the pillar industry of some poverty-stricken areas.Greatly develop meat rabbit animal husbandry, be applicable to China's national situation, it has a high potential, of far-reaching significance.Rabbit diet be take grass as main, is that typical grain-saving type Livestock rabbit belongs to simple stomach Livestock, and in the family of rabbit, the crude feed tolerance ability of meat rabbit is the strongest.
According to statistics, in meat rabbit feed formula, the ratio of raw grain is on average a little more than 20%, livestock and fowl are about 60%, that is to say, meat rabbit has higher digestive utilization ratio to the cellulose in stalk and forage grass, and this is relatively nervous for grain, China that forage grass resource is abundant, greatly develop meat rabbit animal husbandry, be of great immediate significance.
The total energy occurring on feed ingredient and nutritive value table, digestible energy etc. are the indexs that represents fodder energy, be digestible energy (Digestible Energy, be abbreviated as DE) be the contained energy of feed digestible nutrient, animal take in feed can be with fecal energy poor.That is: DE=GE – FE.
(1) total energy: the summation that refers to contained heat energy in carbohydrate in feed, crude fat and crude protein.Through forefathers, study mensuration, 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, corn per kilogram is 16.6 million Jiao, soybean per kilogram is 17.11 million Jiao etc.Total energy in feed can not all be digested and assimilated by poultry, fowl.For example, starch is comprised of glucose, and cellulose is also comprised of glucose, and therefore, their energy is almost all per kilogram 17.57 million Jiao, on calorimeter, measures.But because their structure is different, ruminant can digestibility and utilization part cellulose, non-ruminant animal just can not utilize well.For another example the total energy of corn and corn stalk is close, but corn can be by the energy of livestock digestibility and utilization than corn stalk many 7 times.Therefore, total energy can only illustrate the energy that feed itself has, and can not reflect the energy that poultry, fowl obtain from feed.
(2) digestible energy: be exactly the energy containing in feed digestible substance, the part of namely removing the energy that the material that can not digest contains in feed total energy is energy in excrement.Energy in feed digestible energy=feed total energy-excrement.Each breeding stock, fowl and various different growth phase thereof, digestion power is different, so same feed has different digestible energies.
We know, animal feeding-stuff material composition mostly is vegetal cereals, oilseeds class, piece root crop, 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, cellulose for example, enzyme inhibitor, saponin in alfalfa meal etc., how to overcome the impact that these materials that are unfavorable for animal digestion bring, by plant feed and wherein contain be unfavorable for digestion material be controlled at suitable ratio, can give full play to the energy in feed, and reduce the impact of unfavorable material as far as possible, thereby improve the digestible energy of feed, also improve the conversion ratio of material, realization further improves the feed formula of meat rabbit, improve the conversion ratio of feed, at utmost reduce the consumption of grain, optimize feed formula, make efficiency of feed utilization high, meat rabbit growing way is good, resistance against diseases is strong, fanning economics is good, for the cost of raising enterprise, solve significant, for Feedstuff Enterprises raising product quality and the market competitiveness, also there is significant impetus.
Summary of the invention
For solving the problem existing in background technology, overcome the impact that these materials that are unfavorable for animal digestion bring, further optimize the formula of meat rabbit feed, improve the conversion ratio of feed, the consumption that reduces grain, the present invention aims to provide a kind of meat rabbit feed and preparation method thereof, and it is high that this meat rabbit feed has efficiency of feed utilization, meat rabbit growing way is good, resistance against diseases is strong, the advantage that fanning economics is good.
For achieving the above object, 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%.
