The applied technology of corn is substituted with wheat in birds makings

This year the wheaten price of various places often under corn 100 yuan / ton above, formed wheat and corn price hang. This uses as for wheat cultivate birds feed provided cost basis. The article is brief the applied technique that replaces corn to wheat makes one introduction, mix for feed business breed enterprise reference. Applied condition corn and wheaten feed always can differ very small, but because wheat contains 6-8% Arabia,wood gets together candy, cause feed to feed rotten viscosity in the generation inside enteron big, bring about an animal inferior to the digestive rate of wheaten nutrition. Wheaten part replaces corn but raw material of albumen of effective and spare part dregses of rice like the beans, corn of prep above of wheaten and amino acid content, but dregs of rice under the beans significantly content, if wheat is replaced, the recipe thick albumen level maintains primary level after corn, dregs of rice as a result of the beans dosage drops bring about certain and amino acid (lysine, revive ammoniac acid) drop the quantity is to cannot use wheat to make up for. Must add artificial complex to maintain amino acid content amino acid, and the cost of the recipe before the result can be replaced more than sometimes. Suggest to level of recipe thick albumen raises appropriately after wheat replaces corn, pay close attention to amino acerbity balance. The element on put together and wheat are enzymatic add, the price when every kilograms of wheat is lower than corn 0.1 yuan when, can consider wheaten large proportion to replace corn, reduce the goal of cost in order to achieve. Replace scale with corn - the beans dregses of rice model the recipe is exemple, put forward as follows to suggest. Should use miscellaneous dregs of rice or reduce appropriately when branny bran replace scale. Dosage of the wheat in birds ration: Cheeper birds 10 ~ 20% ; Birds of medium, big, egg 20 ~ 30% , must add get together with wood the wheat that carbohydrase gives priority to is special enzymatic or compound enzymatic. The recipe is adjusted 1. Energy: Wheat is 3040Kcal/Kg to gallinaceous metabolizable energy, under corn 200Kcal/Kg. If wheat replaces corn 30% , energy drops is 40Kcal/Kg, if do not add wheaten enzymatic enough,cause productivity to be able to drop. Consider domestic and internationally to make clear in great quantities, right amount add wood to get together carbohydrase can make the birds metabolizable energy of wheaten ration raises 6 ~ 7% , can make wheaten apparent metabolizable energy rises 7% the left and right sides (140 ~ 230Kcal/kg) . Fall in enzymatic action (assure enzymatic quantity of enzymatic vivid and rather than) , wheat rises 3250Kcal/Kg by 3040Kcal/Kg to birds metabolizable energy, comparative with corn, in add enzymatic circumstance to fall, wheaten metabolizable energy can be equal to have a recipe at corn. 2. Thick albumen: In wheaten price under corn when, in replacing corn simply to be able to improve ration with wheat amino acerbity level. If press nutrition to balance a principle, when identical thick albumen, the metabolizable energy of wheaten recipe, revive ammonia is acerbity, lysine is inferior, need to add oil, revive ammonia is acerbity, lysine, such wasteful. It is especially in pig feed, replace simply more economy. 3. Linoleic acid: Linoleic acid is a kind of indispensible fatty acid. 0.1% linoleic acid are contained to be able to satisfy the need of the pig in ration, wheat replaces corn simply to won't cause linoleic acid inadequacy. 1.5% linoleic acid of 1 ~ are contained to just can satisfy birds in ration kind need, content of wheaten linoleic acid only 0.88% , far under corn 2% content, must regard the most important nutrition as index linoleic acid so. Often need to add costly oil. Consideration nutrition balance and egg can be compared, wheaten dosage is controlled in 40% less than, can achieve economy feasible recipe. 4. Biology element: Cultivate birds is very small to utilization rate of biology of element of the biology in wheat, 5 ~ 55% differ. When using the vitamin premix that takes no account of recipe raw material, take no account of add additionally; The beans dregses of rice dosage amounts to ration 20% when the left and right sides, birds ration need not consider to be added additionally; When using the vitamin premix that considers recipe raw material, add 50mg/kg biology element to be able to be satisfied additionally, the 200mg/kg in total value makings. 5. Phosphor: Natural plant acid is contained in wheat enzymatic, phosphorous content is high, utilization rate relatively jade comes tall, can reduce inorganic phosphor to add a capacity appropriately. 6. Pigment: Wheat contains 2PPm pigment to be the 1/9 of corn only, to fizzling out chicken should add corresponding and artificial pigment or maize gluten pink or lucerne careless pink. Dialogue chicken need not consider. 7. Other: Mutation of wheaten thick albumen is bigger, answer so first assay analysis; The wheat that bare mould pollutes has similar estrogen effect. Treatment controls wheat to regard cultivate birds as feed, cannot smash too fine, affect dainty sex because of papering a mouth otherwise, collect appetite to reduce then. Suggest a wheat flour breaks 4 ~ 6 broken bead is advisable. Have better digestive rate so, can reap tall feed reward. Hammer piece disintegrator is sifted piece it is advisable to choose 3 ~ 3.5mm. Use process is changing makings course in, answer to increase proportion gradually by small proportion, about 7 ~ are finished 10 days change makings course.
