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.

浓缩饲料不能直接饲喂

Concentrated feed cannot be fed directly

浓缩饲料是由蛋白质饲料、矿物质饲料、微量元素、维生素、氨基酸和非营养性添加剂按一定比例配制而成的平均混合物，再与一定比例的能量饲料配合，即成为营养根本均衡的配合饲料。猪用浓缩饲料，普通粗蛋白质含量在35%以上，矿物质和维生素含量也高于猪需求量的三倍以上。因而不能直接饲喂，而必需按一定比例与能量饲料互相配合后才可饲喂。配合时不需求再添加任何添加剂，饲喂时要与粉碎后的能量饲料混合平均，采用生干粉或用冷水拌湿饲喂，并供足清洁的饮水。

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.

猪用浓缩料与饲料原料配比计算办法

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

浓缩饲料与养猪户自产的饲料原料的配合比例一定要合理，才干到达营养均衡。通常在浓缩饲料产品阐明书中，也引荐有与常用饲料原料配合的比例，能够参照运用。但常常所引荐的常用饲料原料与养殖户自产饲料原料不相符，这就需求本人可以计算配合比例。通常都采用简单且易控制的对角线法。现以20～60公斤体重的生长育肥猪为例，阐明这种计算办法。

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：养殖户已购入含粗蛋白38%的猪用浓缩饲料，并有自产的玉米、小麦麸、糠饼三种饲料原料，这三种饲料原料配合比例计算办法和步骤是：步，肯定配合饲料营养程度，生长肥猪营养需求为，消化能12.97兆焦耳/公斤饲料，粗蛋白质16%;第二步，列出自有饲料原料营养成分含量;第三步，依据当地饲料原料和以往经历，初步肯定浓缩饲料的大约配比，大约为20%，然后计算出要配的能量饲料的消化能。

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.
