We may have some mistakes when we buy pig feed. In fact, we determine whether pig feed is good or not. Generally, its smell is based on the inherent smell of feed itself.

眾所周知，如果在豬飼料中適量加入調(diào)味劑，如香味素、甜味素、鮮味劑、咸味劑等，冠農(nóng)濃縮料，能大大提高飼料適口性，豬用濃縮料廠家，冠農(nóng)濃縮料批發(fā)，丹東濃縮料，---食欲和飼料轉(zhuǎn)化率，促進(jìn)畜禽生長。但這些飼料調(diào)味劑的加入并沒有提高飼料本身的營養(yǎng)價(jià)值，只是改變了飼料的物理性狀。

As we all know, if we add seasoning agents, such as flavoring elements, sweeteners, freshness agents and salty agents, guannong concentrated feed can greatly improve the palatability of pig feed. The Pig concentrate manufacturers, guannong concentrated feed wholesale, Dandong concentrated feed, -- appetite and feed conversion rate can promote the growth of livestock and poultry. However, the addition of these seasoning agents did not improve the nutritional value of the feed itself, but changed the physical properties of the feed.

1、作為動(dòng)物生存和生產(chǎn)的能量來源在動(dòng)物生命和生產(chǎn)過程中，維持體溫、隨意活動(dòng)和生產(chǎn)產(chǎn)品，所需能量皆來源于營養(yǎng)物質(zhì)。

1. As the energy source of animal survival and production, in the process of animal life and production, the energy needed to maintain body temperature, move freely and produce products comes from nutrients.

碳水化合物、脂肪和蛋白質(zhì)都可以為動(dòng)物提供能量，但以碳水化合物供能比較經(jīng)濟(jì)。脂肪除供能外還是動(dòng)物體貯存能量的較好的形式。

Carbohydrate, fat and protein can provide energy for animals, but carbohydrate is more economical. In addition to energy supply, fat is also a better form of energy storage in animals.

2、作為動(dòng)物機(jī)體正常機(jī)能活動(dòng)的調(diào)節(jié)物質(zhì)營養(yǎng)物質(zhì)中的---、礦物質(zhì)以及某些---酸、脂肪酸等，在動(dòng)物機(jī)體內(nèi)起著不可缺少的調(diào)節(jié)作用。如果缺乏，動(dòng)物機(jī)體正常生理活動(dòng)將出現(xiàn)紊亂，甚---。

2. As the regulative substance of normal functional activities of animal body, nutrients, minerals and some acids and fatty acids play an indispensable regulatory role in animal body. If lacking, the normal physiological activities of animals will be disordered, even --.

3、作為動(dòng)物體的結(jié)構(gòu)物質(zhì)營養(yǎng)物質(zhì)是動(dòng)物肌體每一個(gè)細(xì)胞和組織的構(gòu)成物質(zhì)，如骨骼、肌肉、皮膚、結(jié)締組織、牙齒、羽毛、角、爪等組織。所以，營養(yǎng)物質(zhì)是動(dòng)物維持生命和正常生產(chǎn)過程中不可缺少的物質(zhì)。

3. As the structural material of animal body, nutrients are the components of every cell and tissue of animal body, such as bone, muscle, skin, connective tissue, tooth, feather, horn, claw and so on. Therefore, nutrients are indispensable in animal life and normal production process.
