There are many kinds of pig feed, which can be divided into additive premix, concentrated feed, full price feed and mixture according to different sources and ingredients. As one of the common feed types, the types and brands of concentrated feed are also very many. If you want to buy good feed, you need to learn to identify the true and false feed. Therefore, the following pig feed manufacturers ask you to quickly distinguish the quality of concentrated feed.

1、觸覺：

1. Tactile:

當人們先要辨別飼料的好壞，那么可以用手指捻畜禽濃縮飼料，觸摸感受飼料顆粒的大小、硬度、粘稠性等，豬用濃縮料作用，通過這些特點也能來判斷飼料優(yōu)劣。

When people want to distinguish the quality of feed first, they can twist the concentrated feed of livestock and poultry with their fingers, feel the size, hardness and viscosity of feed particles by touching, and the effect of concentrated feed for pigs can also be used to judge the quality of feed.

2、味覺：

2. Taste:

當然，你還可以可將少許畜禽濃縮飼料放入口中舔咬，的飼料，味道好，而劣質(zhì)飼料因為選材有問題，所以聞起來有怪味。

Of course, you can also put a little concentrated feed of livestock and poultry into your mouth and lick it. The high-quality feed tastes good, while the inferior feed smells strange because of the selection of materials.

3、嗅覺：

3. Olfaction:

后，大家還可以通過嗅覺來檢驗畜禽濃縮飼料有沒有霉臭、腐臭、氨臭、焦臭等，如果有那么我們可以辨別為劣質(zhì)的飼料。

After that, we can also check whether the concentrated feed of livestock and poultry has mildew, putrefaction, ammonia smell, burnt smell, etc. if so, we can identify it as poor quality feed.

濃縮料是指按照畜禽飼養(yǎng)標準，把各種蛋白質(zhì)原料（如魚粉、豆粕）與一定比例的添加劑混合而成的飼料。濃縮料中蛋白質(zhì)含量在35%以上，各種必需氨基酸、維生素和無機鹽的含量都比較充分，不必另外添加。有些養(yǎng)殖戶自家有玉米、稻谷、小麥等飼料原料，可按畜禽不同的生長階段需求選用不同的濃縮料，配制出不同系列的全價料。

Concentrated feed is a kind of feed made by mixing various protein raw materials (such as fish meal and soybean meal) with certain proportion of additives according to the feeding standards of livestock and poultry. The protein content in the concentrate is more than 35%, and the contents of various essential amino acids, vitamins and inorganic salts are sufficient, so it is not necessary to add them. Some farmers have their own corn, rice, wheat and other feed raw materials, according to the needs of different growth stages of livestock and poultry to choose different concentrated feed, to prepare different series of full price feed.

濃縮料在畜禽日糧中的比例，依其營養(yǎng)含量而異，一般來說可占25－40%。雛禽或幼畜日糧的配比比例為：玉米60%，麥麩5%，濃縮料35%。育成畜禽日糧的配比比例為：玉米65%，麥麩10%，濃縮料25%。育肥期畜禽主要選用高能量低蛋白的飼料飼養(yǎng)，豬用濃縮料批發(fā)，所以，飼養(yǎng)戶只要在能量飼料里添加適量的濃縮料就可以取得良好的飼養(yǎng)效果。濃縮料具有使用簡單、方便的特點，適合小型養(yǎng)殖場和農(nóng)戶使用。

The proportion of concentrated feed in livestock and poultry diets varies according to its nutritional content, generally speaking, it can account for 25-40%. The proportion of the diet for young poultry or young animals is: corn 60%, wheat bran 5%, concentrate 35%. The ratio of corn, wheat bran and concentrate was 65%, 10% and 25%, respectively. During the fattening period, livestock and poultry are mainly fed with high energy and low protein feed, and pigs are wholesale with concentrated feed. Therefore, as long as farmers add appropriate amount of concentrated feed to energy feed, they can achieve good feeding effect. The concentrate is easy to use and suitable for small farms and farmers.
