At present, there are many kinds of concentrated feed consumed in China, and there are also differences in quality. Some of them are even substandard fake and inferior products. Therefore, it is necessary to purchase concentrated feed consumed by manufacturers with reliable quality and quantity. At the same time, the corresponding products should be purchased according to the type, use and growth stage of pigs. The concentrated feed for other animals should not be used for pigs, and the concentrated feed for breeding pigs should not be used for growing and fattening pigs. According to the requirements of the state on the monitoring and management of feed production and quality, all qualified concentrated feed with reliable quality must have product labels, clarifications, certificates and registered trademarks. As long as we control these basic knowledge, we will not be deceived. In addition, the quantity of one-time purchase should not be too much to ensure its novelty and palatability.

濃縮飼料不能直接飼喂

Concentrated feed cannot be fed directly

濃縮飼料是由蛋白質(zhì)飼料、礦物質(zhì)飼料、微量元素、維生素、氨基酸和非營(yíng)養(yǎng)性添加劑按一定比例配制而成的平均混合物，再與一定比例的能量飼料配合，即成為營(yíng)養(yǎng)根本均衡的配合飼料。豬用濃縮飼料，普通粗蛋白質(zhì)含量在35%以上，礦物質(zhì)和維生素含量也高于豬需求量的三倍以上。因而不能直接飼喂，而必需按一定比例與能量飼料互相配合后才可飼喂。配合時(shí)不需求再添加任何添加劑，飼喂時(shí)要與粉碎后的能量飼料混合平均，采用生干粉或用冷水拌濕飼喂，并供足清潔的飲水。

Concentrated feed is an average mixture of protein feed, mineral feed, trace elements, vitamins, amino acids and non nutritive additives in a certain proportion, and then combined with a certain proportion of energy feed, it becomes a formula feed with fundamental balance of nutrition. The content of common crude protein is more than 35%, and the content of minerals and vitamins is more than three times higher than the demand of pigs. Therefore, it can not be fed directly, but must be combined with energy feed in a certain proportion before feeding. No additive is needed in the process of mixing. The mixture should be evenly mixed with the crushed energy feed. Raw and dry powder or cold water mixed with wet feed should be used for feeding, and enough clean drinking water should be provided.

豬用濃縮料與飼料原料配比計(jì)算辦法

Calculation method of ratio of concentrated feed and feed material for pig

濃縮飼料與養(yǎng)豬戶自產(chǎn)的飼料原料的配合比例一定要合理，才干到達(dá)營(yíng)養(yǎng)均衡。通常在濃縮飼料產(chǎn)品闡明書(shū)中，也引薦有與常用飼料原料配合的比例，能夠參照運(yùn)用。但常常所引薦的常用飼料原料與養(yǎng)殖戶自產(chǎn)飼料原料不相符，這就需求本人可以計(jì)算配合比例。通常都采用簡(jiǎn)單且易控制的對(duì)角線法。現(xiàn)以20～60公斤體重的生長(zhǎng)育肥豬為例，闡明這種計(jì)算辦法。

The proportion of concentrated feed and feed raw materials produced by pig farmers must be reasonable in order to achieve balanced nutrition. Usually in the concentrated feed product elucidation, also introduces the proportion with common feed raw materials, which can be used for reference. However, the commonly used feed raw materials often introduced are not consistent with the feed materials produced by farmers themselves, which requires me to calculate the proportion. Generally, the diagonal method is simple and easy to control. This calculation method is illustrated by taking 20-60 kg body weight growing finishing pigs as an example.

例如：養(yǎng)殖戶已購(gòu)入含粗蛋白38%的豬用濃縮飼料，并有自產(chǎn)的玉米、小麥麩、糠餅三種飼料原料，這三種飼料原料配合比例計(jì)算辦法和步驟是：步，肯定配合飼料營(yíng)養(yǎng)程度，生長(zhǎng)肥豬營(yíng)養(yǎng)需求為，消化能12.97兆焦耳/公斤飼料，粗蛋白質(zhì)16%;第二步，列出自有飼料原料營(yíng)養(yǎng)成分含量;第三步，依據(jù)當(dāng)?shù)仫暳显虾鸵酝?jīng)歷，初步肯定濃縮飼料的大約配比，大約為20%，然后計(jì)算出要配的能量飼料的消化能。

For example: farmers have purchased concentrated feed for pigs containing 38% crude protein, and they have three kinds of feed raw materials: corn, wheat bran and bran cake. The calculation method and steps of the proportion of the three kinds of feed raw materials are: step, confirm the nutritional level of the formulated feed, and the nutritional requirements of growing fat pigs are: digestible energy 12.97 MJ / kg feed, crude protein 16%; The second step is to list the nutrient content of self owned feed materials; the third step is to preliminarily confirm the proportion of concentrated feed, which is about 20%, according to the local feed raw materials and previous experience, and then calculate the digestible energy of the energy feed to be prepared.
