What’s the difference between full price and full price?

(the full price material is not as good as the concentrated material, and the concentrated material is not as good as the premix)

it doesn’t matter whether the premix is expensive or cheap. The important things are: 1 How to feed and manage, 2 Improve egg laying rate & nbsp; 3. Improve eggshell quality,

& nbsp; 1. Premix —- mix vitamins, trace elements and amino acids in a certain proportion and add them in a certain proportion when preparing feed. It is an intermediate compound feed product that is evenly mixed with a variety of trace components and diluent or carrier according to the requirements. It can only be fed when it is added to the compound feed

2. Full price feed —- the compound feed that can be directly fed to laying hens after purchase. It contains many kinds of nutrients, high content and appropriate proportion, which can meet all the nutritional needs of laying hens

premix is the abbreviation of additive premixed feed. It is a medium formula feed product made by mixing one or more trace elements (including various trace mineral elements, various vitamins, synthetic amino acids, some drugs and other additives) with diluent or carrier according to the requirements. Premix is an important component of full price compound feed. Introduction to mixture
premix is a homogeneous mixture made of a variety of additives of the same type or different types according to a certain proportion. Because the composition of additives accounts for a small proportion in premix, it is mostly calculated in mg /kg or g /kg. The proportion of premix additives commonly used by dairy cows is 1% – 5%, which is composed of multidimensional elements, trace elements, major mineral elements, some protein feed non nutritional additives and carrier

pretreatment
1. Vitamin pretreatment

(hualuoduowei)

vitamins commonly used in dairy cows include vitamin A, D3 and E. high yield dairy cows also need to add niacin, thiamine and vitamin B12. Due to the small amount of vitamins added, the vitamins are usually pre diluted with a small amount of carrier, and then mixed with a large number of raw materials, so as to ensure the uniform mixing of vitamins/

2. Trace element pretreatment

commonly used trace elements are generally added in the form of inorganic salts, including manganese sulfate, copper sulfate, zinc sulfate, ferrous sulfate, sodium selenite, potassium iodide and cobalt chloride. Some inorganic salts are easy to absorb water and agglomerate, so they must be crushed first. The amount of potassium iodide and cobalt chloride in the premix is very small. In order to mix evenly, they are usually accurately weighed, then dissolved in water in the proportion of 1:15 ~ 1:20 respectively, and then sprayed on stone powder and other carriers and absorbents in the proportion of 1:500 for premixing. Dairy cows also need very little selenium, while sodium selenite is highly toxic, especially hydrophilic and easily soluble in water. Therefore, pretreatment must be carried out. Generally, sodium selenite is added into 81.4 ℃ hot water and completely dissolved for 5 minutes to make 10kg aqueous solution, then sprayed on the rice husk powder in the mixer, mixed evenly to make selenium diluent, and then mixed with other raw materials.

the carrier is a particle that can carry or adsorb a small amount of active added components. After the trace components are carried by the carrier, some of their own physical properties change or no longer appear, and the relevant physical properties (such as fluidity, particle size, etc.) of the obtained “mixture” basically depend on the characteristics of the carrier

3. Carrier requirements

generally, the basic requirements for the carrier are: ① the carrier itself is an inactive substance and has good adsorption capacity for the trace components carried without damaging its activity; ② It has good mixing ability with the main raw materials of compound feed; ③ Good chemical stability and no pharmacological activity; ④ Low price. The so-called diluent refers to the substance mixed in one or more groups of trace active components. It can reduce the concentration of active trace components, separate their particles from each other, reduce the mutual reaction between active components, and increase the stability of active components. The characteristics of the diluent are: ① the diluent itself is an inactive substance and does not change the properties of the additive; ② The relevant physical properties of diluent, such as particle size and relative density, should be as close as possible to the corresponding trace components, and the particle size should be uniform; ③ The diluent itself cannot be absorbed and fixed by active trace components; ④ Diluent should be harmless and edible to livestock and poultry; ⑤ Low moisture content, no moisture absorption, no caking and good fluidity; ⑥ The chemical property is stable without chemical change, and the pH value is neutral, which should be between 5.5-7.5; ⑦ No electrostatic charge. Diluents and carriers commonly used by dairy cows include zeolite powder, stone powder and others with stable chemical properties.

premix has four main functions:

① it can make the trace components of additives evenly distributed in compound feed

② through the pre mixing process, the non ideal characteristics of trace components, such as instability, water absorption, electrostatic adsorption, etc., are compensated and improved

③ standardize the addition level of additives

④ simplify the production process of general feed processing plants and reduce investment

II Use of premixed feed

1 Correctly understand the efficacy of premix

under the condition of intensive large-scale feeding, it must be provided with full price compound feed for animals. To prepare a full price compound feed, premix is essential. We should first consider the nutritional indexes such as crude protein, essential amino acids, energy, calcium, phosphorus, sodium and chlorine in the diet, and then mix with scientific and reasonable premix. Only in this way can we play its role in improving animal production level, reducing feed consumption and health care. To distinguish the role of various nutrients in animal nutrition and their relationship, we should not overemphasize the nutritional and physiological role of premix. The role of premix can be shown only on the premise that the main nutritional indicators in the diet are reasonable

2. Reasonable selection of premix

premix sold in the market is mixed, and some have problems such as unqualified quality and unreasonable formula. When purchasing, premix must be selected and used according to local conditions according to their own feed raw materials

if you only have energy feed raw materials, you should choose full nutrition concentrate; If there are both energy feed raw materials and protein raw materials, the compound premix with an addition of 2% ~ 3% can be selected

& nbsp;& nbsp; In case of feed plant, 1% ~ 2% compound premix produced by professional premix plant or 0.1% ~ 0.5% high-tech classified premix can be selected

& nbsp;& nbsp; Premix products produced by manufacturers with strong technical force, complete product specifications, stable quality and thoughtful after-sales service shall be selected

Pu Lida in Xuzhou is good. According to the types of local agricultural and sideline products, select the formula type suitable for the types and characteristics of their own base materials

many people still don’t understand the specific concepts of full price feed, concentrated feed and compound feed. Let me popularize the relevant concepts. It is estimated that this time is also more comprehensive. If you think it is useful, you can also try to collect it

compound feed

is based on animal nutrition and feed resources, and then many feed raw materials are mixed and matched according to a certain proportion. What we call full price feed and concentrated feed belong to compound feed. It is only divided according to its nutritional composition. Of course, you can also divide it according to its physical shape, including powdered feed, pellet feed, broken grain feed and expanded feed. You can also divide them according to different kinds of animals. Chicken feed, cattle feed and sheep feed belong to compound feed. Therefore, compound feed is a very huge system, and the feed we use can basically be called compound feed. In general, we can divide according to the nutritional composition

1. Full price feed: this kind of feed has all kinds of nutrients, which can basically meet the needs of animals. The feed that can be fed directly without adding other ingredients is generally composed of energy feed, protein feed, mineral feed and various feed additives. In our country, poultry and pigs are used more

2. Concentrate supplement: it is mainly suitable for herbivores. It is mainly composed of energy feed, protein feed, mineral feed and feed additives. We usually let cattle and sheep eat roughage and green feed, and then supplement such feed together

3. Energy feed: this kind of feed is mainly composed of grain feed to provide energy for livestock. Especially the starch in plant feed and the oil we use can be called energy feed

3. Protein feed: our common cognition is meat and soybean milk. In fact, in-depth research is that soybean meal, peanut miscellaneous meal, silkworm chrysalis, Tenebrio molitor and some protein feeds synthesized by microorganisms

concentrated feed: concentrated feed is prepared by protein feed, mineral feed and feed additives in a certain proportion, that is, the part of the full price feed excluding the energy feed

additive premix

additive premix is also a kind of compound feed, and it is also the core of compound feed. When evaluating some full price feed, the quality of additive premix sometimes determines the quality of full price feed. Adding their own premix is to mix feed additives with carrier or diluent, because some feed additives are easy to be oxidized, very unstable, and some are not easy to be absorbed, so carrier and diluent should be used

1. Single premix: single premix is prepared from the same kind of feed additives. It may be trace elements or vitamins

2 Composite premix: refers to the mixture of two or more of trace elements, vitamins and amino acids mixed with carrier and diluent. Generally, the preparation steps of this feed are cumbersome and the preparation process is difficult, which is more difficult than a single premix

premix can also be understood as a mixture prepared by mixing trace elements, vitamins, amino acids and various drug additives. Of course, if it is composed of the same kind, it is a single premix. If it is composed of more than two kinds, it is a compound premix

1. Single premix is a homogeneous mixture prepared from a single additive raw material or a variety of feed additives of the same kind and carrier or diluent. It is mainly due to the small amount of one or more additives, which requires primary premixing to be more evenly distributed in bulk feed In production, single vitamins, single trace elements (selenium, iodine, cobalt, etc.), multiple vitamins and multiple trace elements are pre mixed into single premix respectively
2. Compound premix is prepared according to formula and
