What does 8% Mineral premix for swine mean? Does it really work?
8%, 10% or even 12% of pig feed has gradually entered the field of vision of our farmers. Strictly speaking, only feeds with a proportion of less than 10% can be called premixes. What exactly is 8% more than a 4% premix? Is it more valuable? Which one is better, 4% or 8%?
Therefore, from the formulation to the cost of use to the effect of the product, we will introduce the 8% premix in detail from three aspects.
The premix that we usually call, the full name should be "compound premix feed", it is a kind of compound feed, which contains vitamin premix, mineral premix, drug additives and functional additives.
【4% premix formulation analysis】
Take the conventional 4% premix formula as an example. 30% are fillers, i.e. carriers. Without a carrier, the content of vitamins and trace elements cannot be uniformly mixed, and problems will occur during use. The principle is very simple, just like we farmers grow vegetables, the seeds are very small. For even distribution when sowing, we mix the seeds in sand or fine soil.
Typically a 4% premix contains less than 10% amino acids, less than 5% minerals, less than 2% drugs and less than 1% vitamins. If these low levels are to be mixed together without delamination, moisture or reaction, a carrier with good load-carrying capacity and good flow is required. 20-25% is stone powder, which provides calcium ions for pigs, and calcium hydrogen phosphate is 10-20%, which provides phosphorus for pig growth.
The above are the general ingredients and contents of the premix. Back to the topic, what exactly is 8% more premix than 4%?
[8% premix formulation analysis]
Premix manufacturers usually have two methods of operation:
The first method is to double the dilution of 4% to 8%, i.e. 200 kg originally, now add 100 kg. The original useful substance content is 70% and the current content is 35%. The remaining space is filled with the carrier. This is the practice of unscrupulous businessmen, not the mainstream of the market. In the words of our farmers, these are all hype concepts.
The second method is to add some functional additives or high-protein raw materials on the basis of 4%, such as fish meal, whey powder, soybean powder, etc., and increase the nutrition of the premix by adding high-protein raw materials or additives to enrich the premix. The efficacy of the compounding can be made into differentiated and special products. In theory, the price of this type of 8% product must be higher than 4%, and the product use effect should also be higher than 4%.
2. Cost of use
So is it more expensive to use 8% premix? That is for sure! With so many useful nutrients added, and the cost of most nutrients being higher than the average cost of a premix, it naturally increases the price of the premix.
But the high price of premix does not mean that the cost of use will be greatly increased.
Let's take the formula for an 8% premix as an example:
Taking the online sales of 4% piglet premix and 8% piglet premix as an example, the price of 8% premix formulated into full-price feed is about 400 yuan/ton higher than that of 4%. If the 8% premixed products sold by e-commerce are compared with the 4% premixed products sold through traditional channels, the price per bag is only RMB 55 higher, which is nearly RMB 2250/ton lower than the full price. The cost of use is greatly reduced.
With the current low price of live pigs, 8% is a good choice if you want to pursue better feeding results.
