Description

A kind of reduce feedstuff broiler chicken batch just and production method
Technical field
The present invention relates to field of fodder, be specifically related to a kind of reduce feedstuff broiler chicken batch just and production method.
Background technology
In recent years, due to the impact of environment, the quality of bulk feed raw material is uneven, and bad environmental microorganism pressure increases Greatly;Meanwhile, along with improving constantly of broiler chicken production performance, its susceptibility strengthens, and the ability of anti-stress reduces.At broiler In breeding process, occurring that feedstuff phenomenon just gets more and more, the persistent period is more and more longer, and economic loss is increasing.Feedstuff just, Refer to the nutrition leak phenomenon occurring in feces because of intestinal digestion or absorption problem.Feedstuff will cause growth of meat chicken not Good: it is low to deliver body weight for sale, feedstuff-meat ratio is high, and colony's uniformity is poor, and broiler cannot be delivered for sale with criticize, and survival rate is low.
Formula feed of broilers is to provide energy and the main substance of basic nutrition material for broiler chicken, broiler growth and Various vitamin needed for maintenance, macroelement, trace element are also relied on from feedstuff obtaining.People design and prepare various meat Chick compound feed prescription meet broiler chicken each stage growth with maintain needed for feedstuff.And produce feedstuff broiler chicken just Digestibility and the deficiency of weightening finish to batch, survival rate and the reduction of the uniformity, always restriction broiler chicken productivity The key factor that can play.
Summary of the invention
For defect present in prior art, it is an object of the invention to provide a kind of feedstuff broiler chicken just that reduces and join Closing material, this feedstuff can be effectively improved the broiler chicken utilization rate to feed nutrient, and can improve broiler chicken growth performance, Nutritive digestibility and intestinal health, reduce feedstuff just incidence rate.
Present invention also offers a kind of production method reducing feedstuff broiler chicken batch just.
Thering is provided a kind of broiler chicken batch reducing feedstuff just, its raw material forms and weight proportion is: Semen Maydis 30-70 weight Part, bean cake 20-30 weight portion, Fructus Hordei Vulgaris 3-15 weight portion, Semen arachidis hypogaeae dregs 1-9 weight portion, distiller grains albumen dregs of rice 1-9 weight portion, Oleum Glycines 1-3 Weight portion, stone powder 0.5-2 weight portion, calcium hydrogen phosphate 0.5-1.5 weight portion, Sal 0.1-0.5 weight portion, compound vitamin 0.01-0.03 weight portion, mineral element 0.1-0.3 weight portion, L-lysine sulfate 0.1-0.5 weight portion, DL-methionine 0.1-0.3 weight portion, L-threonine 0.01-0.05 weight portion, choline chloride 0.05-0.3 weight portion, phytase 0.01-0.03 Weight portion, compound protease 0.03-0.1 weight portion, probiotics 0.03-0.3 weight portion, prebiotics 0.03-0.3 weight portion and acid Agent 0.1-0.5 weight portion.
