Abstract
The invention discloses feed for medium and large-sized pigs. The feed comprises the following components in parts by weight: 10-50 parts of sorghum, 10-30 parts of cassava, 5-30 parts of barley, 0-10 parts of bean meal, 5-15 parts of rapeseed meal, 5-15 parts of DDGS, 0-10 parts of rice bran and 0-10 parts of maize. According to the feed provided by the invention, the amount of maize, bean meal and the like in the feed for medium pigs is greatly reduced, the feed ratio is increased and meanwhile, the quality and the yield of pork are improved.
Description
Technical field
The present invention relates to field of fodder, more specifically, relate to a kind of medium-and-large-sized pig feed.
Background technology
Along with the development of feed industry, applied widely based on the full-valence pellet feed of corn-soybean meal diet, but meanwhile, the continuous increase of the industry such as grocery trade and brewing industry to corn consumption, cause fodder maize increasingly in short supply, price climbs up and up, and price was from 2.6 yuan/more than the kg rising to 2014 less than 1 yuan/kg of 2000, and some time period, indivedual provinces and regions fodder maize price was even up to 2.6 ~ 2.8 yuan/kg.From the current energy feed state between supply and demand of China, be only obviously difficult to by corn yield increasing the breach making up energy feed.According to estimates, the breach of China 2000-2020 energy feed rises to 8,000 ten thousand tons by by current 3,000 ten thousand tons, and the regionality of China's Maize Production is strong, North China and northeast 6 province corn total output account for 60% of the whole nation, and southern 8 province's corn yields only account for 20% of the whole nation.The south of northern com is adjusted, and greatly will increase feed cost, increases the weight of communications and transportation burden.
Feed cost accounts for 70% of totle drilling cost of raising pigs, and feedstuff will become the key restriction factors of Science in Future in China aquaculture.Within a certain period of time, select cost performance suitable raw material often decides Feed Enterprise, whether breeding enterprise gains.
Summary of the invention
How reducing the content of corn in feed, is technical problem extremely urgent at present, and while will accomplishing that reducing corn uses, ensures the quality of medium-and-large-sized pig.
In order to solve above technical problem, the invention provides a kind of medium-and-large-sized pig feed, comprise following composition, by weight, Chinese sorghum 10 ~ 50 parts, 10 ~ 30 parts, cassava, barley 5 ~ 30 parts, dregs of beans 0 ~ 10 part, the dish dregs of rice 5 ~ 15 parts, DDGS5 ~ 15 part, 0 ~ 10 part, rice bran and corn 0 ~ 10 part.
Also comprise multidimensional many ore deposits premix 2.5 parts, complex enzyme 0.02 ~ 0.03 part, antimicrobial peptide preparation 0.05 ~ 0.1 part and meat improved additives 0.1 part.
Preferred version is, comprises following composition, by weight, and Chinese sorghum 30 ~ 50 parts, barley 5 ~ 15 parts, 15 ~ 30 parts, cassava, the dish dregs of rice 5 ~ 15 parts, DDGS6 ~ 15 part, dregs of beans 0 ~ 10 part, corn 0 ~ 10 part and 0 ~ 10 part, rice bran.
Preferred version is, by weight, and Chinese sorghum 10 ~ 50 parts, 10 ~ 30 parts, cassava, barley 5 ~ 30 parts, dregs of beans 0 ~ 10 part, the dish dregs of rice 5 ~ 15 parts, DDGS5 ~ 15 part and 0 ~ 10 part, rice bran.
Preferred version is, the content of described dregs of beans, rice bran or corn is not 0.
At least containing zytase and 1,4 beta-glucanase in described complex enzyme; By weight, every kg contains meat improved additives: selenium methionine 0.1 ~ 0.35mg/kg, magnesium aminosuccinate 1500 ~ 3500mg/kg, chromium picolinate 0.2 ~ 0.6mg/kg and 50 ~ 200mg/kg vitamin E.
Described Chinese sorghum is low tannin Chinese sorghum, cassava through the airing of 3 ~ 4 days, and control moisture below 14%.
Chinese sorghum is large in the cultivated area of China, output is high, and nutritious, cheap, and the cultivated area of China jowar occupies the 5th, the world, and the South and the North all can be planted.At present part studies proof, adds a certain proportion of Chinese sorghum and not only can substitute a part of corn in feed, and to feed livestock and poultry as the feed of pig, milk cow, beef cattle, poultry and fish etc., has certain effect.Chinese sorghum and corn conventional nutrient value ratio comparatively the results are shown in Table 1 (unit: %).From conventional nutrient content, Chinese sorghum is a kind of rare excellent energy feed raw material of replacement of corn.But owing to containing more tannin in Chinese sorghum skin, it has convergence and bitter taste, is a kind of ANFs, affect palatability and the metabolism of animal, hinder animal to the nutrien utilization such as energy and protein, particularly nonruminant, tannin can reduce its utilization rate to protein and mineral matter.Research shows, in feed, tannin content has a strong impact on more than 0.5% pair of animal, lower than 0.1% then almost without impact.Li Xiaoqian etc. are hybridized low tannin Chinese sorghum with KS-304 and are fed pigs, and experimental result shows, replace diet corn to be feasible, do not affect the speed of growth of pig, daily ingestion amount and the price of deed by 10% ~ 20% equivalent.Therefore, in little swine rations, low tannin Chinese sorghum (tannin content is lower than 0.4%) is comparatively suitable.
Cassava is tubers energy feed raw material, and containing abundant carbohydrate, its nutrient composition content is in table 2.Because cassava can be worth higher, in mixed feed, common using method is the energy feed that the price such as replacement of corn or wheat is higher.The average dry digestibility that cassava does is 75%, and organic matter digestibility is higher than 85%, and starch digestibility is up to 87% ~ 89%, close with cereal.Containing NFE about 31% in fresh tapioca root, be made up of the starch of 80% and the sugar of 20% and acid amides, be thus easy to by animal digestion.Dry cassava slice or cassava particle almost do not have mould contamination, not only to safeguarding that animal health has great advantage, can also reduce the use of mould inhibitor in feed.The cassava deficiency done nutritionally shows following four aspects: the first, and protein content is low, and amino acid content is few, and especially sulfur-containing amino acid is lower, thus in cassava daily ration except increasing except protein feeds, also should consider to add sufficient sulfur-containing amino acid; The second, fat content is low, and some essential fatty acid contains quantity not sufficient, as linoleic acid; Mineral Concentrations is except total phosphorus and iron are lower than except corn, and all the other are suitable with corn.3rd, lack liposoluble vitamin, choline and lutein, if consumer has requirement to yolk color, need in feed to add pigment to meet customer need; 4th, cassava contains hydrocyanide---linamarin and lotaustralin, and the hydrocyanide content of different cultivars cassava is different, with tapioca root dry basis, be generally 150-1500ppm, by the improvement of related gene, the new varieties containing Microamounts of Hydrogen cyanide may be cultivated.Linamarin, under the linamarin enzymatic coexisted with it, can produce hydrogen cyanide.Hydrogen cyanide in animal body with metal ion as iron and copper have affinity, the compound formed can be combined with hemoglobin, hinder the fortune oxygen function of hemoglobin, cause that animal breath is rapid, pulse is accelerated and muscle cramp, cerebral anoxia can cause central nervous system impaired and then cause death simultaneously.Pig, sheep take in 0.1 ~ 0.2g, horse, ox take in 0.4 ~ 0.5g can be lethal in several minutes.During slight or chronic cyanide poisoning, Animal performance is metabolism disorder, poor growth.In cassava, the suggestion level of security of hydrogen cyanide is 100ppm, and containing hydrogen cyanide 15 ~ 400ppm in common Cassava Cultivars.Common processing method is by airing after manioc root section 3 ~ 4 days.Because hydrogen cyanide is volatilizable in air, if the dry moisture of cassava controls below 14%, its hydrogen cyanide content can be reduced to the average level of 30ppm, thus reduces its toxic action greatly.In addition, hydrocyanide can be changed into thiocyanates and cyanocobalamin acid by employing sulfur-containing amino acid thus remove the toxicity of hydrocyanide by animal self.
Hordeum cereal crop cultivated area accounts for the 6th of whole world cereal crops, the main place of production comprises the wide area in Russia, Canada, Australia, European Union member countries and North America, also there is extensive plantation in China, annual production has reached more than 700 ten thousand tons, cultivated area throughout the whole nation, the particularly provinces and cities such as Hubei, Anhui, Jiangsu, Zhejiang, Shanghai of the middle and lower reach of Yangtze River.Barley is as southern energy feed resource, and mould bad rate is low, good palatability, and be applicable to pig feed and produce, have DEVELOPMENT PROSPECT, its nutrient composition content is in table 3.Barley nutritive digestibility compared with corn is lower, and Feeding Value is equivalent to 90% (see table 3) of corn, and reason is the existence of ANFs in barley, and solubility NSP is the Main Antinutritional Factors of barley.ANFs can increase chymeviscosity, nutrition barrier.Change intestinal microflora, reduce fodder energy.But can by pulverizing, the mode such as expanded, granulation, and adding complex enzyme preparation special to improve barley feeding effect, for Substitute For Partial in pig feed or whole corns, having very important significance to reducing feed cost.

Along with improving constantly of people's living standard, people have higher requirement to pork quality, and pork not only wants healthy, health, but also wants mouthfeel good; On the other hand, pork distributors also proposes special requirement to meat quality---ruddy color, minimum moisture loss, longer shelf life.But, along with the popularization of breeding pig and the raising of raise competence, consumer more and more complains that meat taste is coarse, color is pale, weak point of having a nasty taste etc., and the requirement that can pork quality meet consumer and retailer will directly affect enthusiasm and the fanning economics of raiser.
The development of China's live pig breeding industries, kind is introduced and the advantage of character improvement represents day by day: the pork pig speed of growth significantly improves, and marketing time shortens gradually.In addition; along with the continuous progress of Pig Industry industry relevant technical; China's pig-breeding industry moves towards intensive gradually, scale, mechanization, automation pattern of raising pigs; under this feed formula technology of raising pigs pattern and modern nutrition science is actuated; the production performance of pork pig more obtains very big performance; the speed of growth of a pig from wean to market weight 115kg less than 150 days is that speed is surprising.But pork pig grows fast, also the problem of a series of metabolism and nutrition aspect is brought, as pig body anti-stress ability extreme difference, hypoimmunity, the ability that opposing external environment stimulates also weakens relatively, thus there is the phenomenon such as " drip meat ", " white muscles ", " mouthfeel is poor ", make to raise pigs dealer improving swinery anti-stress ability, improving in immunity and spend all hardship, also become the principal element of serious restriction pig industry development.If the research of these aspects can make progress will bring direct economic benefit to live pig industry.
Selenium is affirmed fully as its nutritive effect of a kind of Trace Elements, scarce selenium can cause animal muscle malnutrition, breeding is obstructed, is lost weight, by supplementing appropriate selenium to animal, can promote that animal health grows, improve the quality of animal products, and then improve the diet nutritional of the mankind.Traditional mode of production generally uses the source of inorganic selenium selenium as a supplement, and between its effective dose and toxicity dose, scope is narrower, and animal easily occurs poisoning, and absorptivity is low, and unabsorbed selenium is discharged by ight soil, to environment.Organic Selenium has features such as absorbing soon, utilization rate is high, pollution is few, and can pass through its distinctive metabolic pathway, is deposited in the middle of musculature, improves the quality of meat with organic form.There are some researches show, Organic Selenium can improve livestock and poultry production performance and meat (Clyburn etc., 2002; Yang Hua etc., 2004; Zou Xiaoting etc., 2005), but also have some reports to think that Organic Selenium does not possess above-mentioned functions (Mahan etc., 1999; Payne etc., 2005; Ding Binying etc., 2006).The external research to Organic Selenium is mainly based on yeast selenium, and selenomethionine (Se-Met) only has a small amount of research to the effect on livestock and poultry.Account for elegant peace wait (2004) result of study show to add in diet selenomethionine can obviously improve fattening pig kill after yellowish pink in fresh meat placement 16h, and significantly reduce the drip loss of fresh meat in 8 ~ 16h, general effect is better than adding sodium selenite, especially along with the prolongation of fresh meat external time, this advantage heals and becomes obvious.(1999) and the Edens etc. (1997) such as the result of the test of selenomethionine reduction fattening pig fresh meat drip loss and Manhan use the result of study of yeast selenium basically identical.It is very favourable to improving pork color that Jiang Zong bravely waits (2010) result of study to show in Diet For Finishing Pig, add 0.15 ~ 0.30mg/kg selenomethionine selenium.But selenomethionine content is only 50%, all the other complicated components, effect in actual production is unstable, therefore, for employing high-purity selenomethionine, study the impact of its meat such as yellowish pink and drip loss on fattening pig fresh meat, for the suitability for industrialized production of selenomethionine and the application of the science in feed thereof provide foundation.
Chromium is considered to toxic element always, until nineteen fifty-nine Schwartz etc. (1959) propose GTF (GTF) hypothesis, is just familiar with gradually and payes attention to its biological function, disclosing the Study and appliance prospect that chromium is wide.The Study and appliance of chromium in pig nutrition starts from the nineties in 20th century, though start late, development rapidly.Research is thought, the main Physiological Function of chromium may be the constituent as GTF, strengthens the activity of insulin, thus impact sugar, fat and protein metabolism, change deposition and the utilization orientation (Wu Yongsheng etc., 2000) of metabolism.According to the literature, add chromium picolinate in diet, store pig can improve the speed of growth, improves feed efficiency, improves lean meat percentage, reduces the thickness of backfat, increases eye muscle area (Page etc., 1993); Brood sow can increase nest litter size and the number of live birth, improves piglet growth performance, improves 21 age in days litter weight and number pigs weaneds, improves piglet survival ratio (Lindem etc., 1995).Much research also shows, adds Organic Chromium also some immune response of adjustable animal in diet, alleviates the stress situations such as the nutrition of pig, environment and metabolism, reduces the loss that stress cause animal productiong.China attaches great importance to the application study of Organic Chromium in Animal nutrition and feed in recent years, and document announcement is increasing, and the product of research and development is quite a few, as chromium picolinate, yeast chromium, nicotinate chromium etc.Xia Zhongsheng etc. (2002) result of study shows to add organic Chroma-Pak in full phase diet, can improve the production performance of store pig to a certain extent, improves daily gain and efficiency of feed utilization; And Swine serum biochemical indicator is not seemingly made significant difference.Full phase interpolation or only later stage add organic Chroma-Pak and all can increase carcass lean meat percentage, reduce body fat and improve carcass quality, and better with later stage additive effect.Xie Zhongfei etc. (2004) result of study shows that in daily ration, to improve the effect of fattening pig carcass quality best to add 0.2mg/kg chromium picolinate.Wang Shenglin etc. (2004) result of study shows that Chinese herb feed additive, zinc methionine, chromium picolinate and acidulant all can strengthen grower pigs breaks down proteins under the high temperature conditions and gluconeogenesis, and then improves production performance.Dong Hongwei etc. (2010) result of study shows that chromium picolinate can significantly improve the daily gain of growing and fattening pigs and obviously reduce feedstuff-meat ratio, improves the carcass quality of growing and fattening pigs, in finishing pigs diets, therefore adds chromium picolinate have important practical significance.But relevant report not the same (Zhang Wei etc., 1999), need study further, applying for it provides foundation.
Magnesium is the confactor of many metabolism and enzyme in body, can regulate and control meat by neural and functions of hormones.Magnesium can reduce the amount of cortisol and catecholamine in blood plasma, reduces the metabolism of glycogen, thus reduces glucolytic generation, reduces the secretion of lactic acid, makes the pH of muscle remain on higher level.Thus magnesium can reduce and on the impact of meat quality, stress particularly reduce the generation of PSE meat.Daily ration interpolation magnesium improves meat quality and has relevant report (Souza etc., 1998; Schaefer etc., 1993).Chen Daiwen etc. (2006) have studied the impact of magnesium aminosuccinate on meat quality adding varying level at basal diet a middle or short term, its result shows: when the addition of magnesium (magnesium aminosuccinate) is at 2500 ~ 3200mg/kg, reach maximum to the improvement result of pH, drip loss and yellowish pink, now in serum and muscle, the content of magnesium is about 0.90mmol/L and 241mg/kg.Xu great Jie etc. (2010) result of study shows that in daily ration, supplementary chromium picolinate, magnesium aminosuccinate, chromium picolinate+magnesium aminosuccinate all reduce Determination of cortisol in serum, slow down on the hoof stress reaction; Supplement chromium picolinate, chromium picolinate+magnesium aminosuccinate to the growing and fattening pigs before killing and all can reduce the rear decomposition of glycogen (P<0.05) of government official, glycogenolytic trend after supplementary magnesium aminosuccinate also has reduction to kill.Supplement chromium picolinate, magnesium aminosuccinate and chromium picolinate+magnesium aminosuccinate and all significantly can reduce pig longissimus dorsi muscle and biceps muscle of thigh lactic acid content (P<0.05) in government official's rear short time; Supplement chromium picolinate, magnesium aminosuccinate and chromium picolinate+magnesium aminosuccinate in daily ration and all extremely significantly (P<0.01) longissimus dorsi muscle and biceps muscle of thigh pH and drip loss can be reduced, reduce PSE meat incidence 75.1%, 49.8% and 75.1% (P<0.05) respectively, and (P>0.05) is not made significant difference to Coefficient shrinkage); It is all remarkable in adding separately chromium picolinate, magnesium aminosuccinate group that compound adds chromium picolinate, the drip loss of magnesium aminosuccinate group pig, longissimus dorsi muscle and biceps muscle of thigh colour, this illustrates that chromium picolinate, magnesium aminosuccinate have certain additive effect improving in pork quality traits, and additive effect is best simultaneously for the two.
Vitamin E have α-, p-, γ-, δ-etc. 8 kinds of forms, wherein the highest with alpha-tocopherol activity, its structure is made up of the isoprenoid side chain of 6-hydroxychroman ring and 16 carbon atoms, hydroxyl on chroman ring is relevant with antioxidation, it provides a hydrogen can to the free radical of moon purport class, have an effect with free electron, suppress free radical, thus suppress the chain reaction of lipid oxidation.Vitamin E also has anti-heat stress, improves the effect of immunity and fertility of sow.Li Shaohua etc. (2009) result of study shows that body weight is add vitamin E (200 milligrams every kilogram) in the fattening pig diet of about 60 kilograms, continues to feed more than 35 days, and the yellowish pink of examination pork is scarlet, pH is normal; Coefficient shrinkage is good, and the process wherein adding vitamin is extremely significantly better than control group (P<0.01); Drip loss, 412 Water Unders divide leaching rate low; Obviously extend the shelf-life of fresh meat.In fattening pig diet, add vitamin E, continue suitable time of feeding, the Meat Quality of pig can be improved, increase the economic benefit of pig industry.Sun Jun etc. (2010) have inquired into vitamin E and have added the time to the impact of DLY growing and fattening pigs trunk meat parameter, and its result shows that vitamin E needs feeding time section before certain government official to the effect improving DLY meat.
In sum, Organic Selenium (selenium methionine), Organic Chromium (chromium picolinate), organic-magnesium (magnesium aminosuccinate), highly effective vitamin E etc. have positive improvement result to fattening pig carcass quality, add application and to have no side effect and respond well.
Compared with pig feed in conventional corn, bean pulp type, the present invention has following advantages:
1, adopt amino acid balance daily ration technology, the amino acid of feed balances more; Add Non-starch Polysaccharides Enzyme, energy, the albumen digestibility of feed are significantly high, in large pig growth performance exceed traditional corn soybean meal based diets;
2, swinery resistance against diseases and immunity can be improve, reduce antibioticly in breeding process using and remaining;
3, effectively can improve and deliver pork quality for sale, improve pig flesh flavor and quality;
4, the present invention can significantly reduce feed formula cost, compared with traditional corn, soybean meal based diets, per tonly saves feed cost more than 300 yuan.
