1. It is convenient and labor-saving, replacing inefficient personal production with large-scale and high efficiency of feed company, which can save part of processing cost while saving labor cost.

2.原料有保证：原料低，质量好，造假技术日益，让人士都头痛，一般规模的养殖场根本无法分辨掺假原料，而饲料公司有精确的化验设备，能确保原料的质量；同时饲料原料的大量、成批采购具有成本优势。

2. Guaranteed raw materials: the low price, good quality and increasingly sophisticated counterfeiting technology of raw materials make the professionals have a headache. In general scale farms, adulterated raw materials cannot be distinguished at all, while feed companies have accurate testing equipment to ensure the quality of raw materials; at the same time, large quantity and batch purchase of feed materials have cost advantages.

3.搅拌均匀度好：个人饲料器械只适合搅拌10%以上的预混料。一般的立式搅拌机只有20%的搅拌系数。因此只占1%或4%猪预混料很难搅拌均匀。

3. Good mixing uniformity: personal feed equipment is only suitable for mixing more than 10% premix. The general vertical mixer has only 20% mixing coefficient. Therefore, only 1% or 4% of the pig premix is difficult to mix evenly.

4.营养互补：就象人的食物，要求要多样化；同一个道理。猪的也是一样，浓缩料能充分利用多种原料配合，使氨基酸达到平衡互补，就是大家熟悉的“木桶理论”。 而猪预混料的原料相对较单一。

4. Nutrition complementation: just like human food, it requires diversification; the same principle. The same is true for pigs. The concentrate can make full use of a variety of raw materials to achieve the best balance and complementarity of amino acids, which is known as the "barrel theory". The raw material of pig premix is relatively single.

5.油脂：油脂是猪日粮中必不可少的。不饱和脂肪酸的作用不容忽视；同时也是脂溶性维生素的载体，促进吸收。而猪预混料中是加不进的。

5. Fat: fat is essential in pig diet. The role of unsaturated fatty acids can not be ignored; it is also the carrier of fat soluble vitamins, promoting absorption. The pig premix is not added.

6.加工：豆粕的生熟程度不同，具有不同程度的营养吸收抑制因子（比如胰蛋白酶抑制因子），而一般性的粉碎是很难破坏的；而大规模的饲料厂生产工艺不同，能很好的破坏营养吸收抑制因子，更促进营养的吸收，使饲料得到充分利用。

6. Processing: soybean meal has different degrees of maturity and nutrition absorption inhibition factors (such as trypsin inhibition factor), but general crushing is difficult to destroy; while large-scale feed factories have different production processes, which can destroy nutrition absorption inhibition factors, promote nutrition absorption and make full use of feed.

在预混料没有优势的情况下，在保证浓缩及配合料质量稳定的前提下，生长速度肯定会明显快于预混料。

Under the condition that premix has no price advantage, and on the premise of ensuring concentration and stable mixture quality, the growth rate will be obviously faster than premix.
