8%, 10% or even 12% of the pig premix gradually into our farmers' vision, strictly speaking, the proportion of less than 10% of the feed can be called premix. Compared with 4% of the premix, what is more valuable in the 8% pig premix? Which is more suitable for 4% and 8% pig premix?
From this, from the formula to the use cost and then to the use effect of the product, three aspects are introduced in detail about the 8% premix.
1、 Premix formulation
People usually call premix, the full name should be "compound premixed feed", which includes vitamin premix, mineral premix, drug additives and functional additives.
Analysis of 4% premix formula
Take a conventional 4% premix formula as an example. 30% is the filler, that is, the carrier. Without the carrier, the small content of vitamins and trace elements can not be mixed evenly, and problems will occur when using it. This principle is very simple. For example, when we farmers grow vegetables, the seeds are very small, in order to sow evenly, we will mix the seeds in sand or fine soil. In the 4% premix, amino acids account for less than 10%, minerals less than 5%, drugs and vitamins less than 2%, less than 1%. If we want to mix these low content substances together, and ensure that they are not stratified, not affected by moisture, do not react, we need a carrier with good bearing capacity and good fluidity. 20-25% is stone powder, which provides calcium ion for pigs, and 10-20% is dicalcium phosphate, which provides phosphorus for pig growth.
These are the conventional ingredients and contents of premix. Back to the point, what's more about 8% premix than 4%?
Analysis of 8% premix formula
Premix manufacturers generally have two methods of operation:
The first method is to dilute 4% to 8%, that is to say, the original 200 kg is added, and now 100 kg is added. The content of the original useful substance is 70%, and now the content is 35%. The remaining space is filled with carrier. This is the practice of unscrupulous businesses, not the mainstream in the market. In the words of our farmers, these are the concept of speculation.
The second way is to add some functional additives or high protein raw materials, such as fish meal, whey powder, soybean meal, etc. on the basis of 4%, the nutritional level of premix can be improved by adding some high protein raw materials or additives which are inconvenient for customers to buy, so as to enrich the functions of premix and make products with alienation and characteristics. Theoretically speaking, the price of 8% products of this type must be higher than 4%, and the effect of products should be better than 4%.
2、 Cost of use
Is it more expensive to use 8% premix? That's for sure! Adding so many useful nutrients, and the cost of most nutrients is higher than the average cost of premix, which will naturally increase the price of premix.
Taking online sales of 4% piglet premix and 8% piglet premix as an example, the price of full price feed prepared with 8% premix is about 400 yuan higher than that of 4%. If the 8% premix products sold by e-commerce are compared with the 4% premix sold through traditional channels, the price per bag is only 55 yuan higher, nearly 2250 yuan per ton lower than the full price materials. The use cost is greatly reduced.
In the current situation of low pig price, 8% is a good choice to pursue better feeding effect
