Mockup Provider » Q: How To Make Pig Feed?

The pig is among the most populous large mammals in the world. It is the most commonly consumed meat worldwide. Pigs are omnivores and can consume a wide range of food. There is a large market on pig feed production.

What Is Pig Feed? 

Pig feed is divided into 2 types, first is raw feed which is not artificial feed. It mainly includes the following types.

1. Coarse feed: It refers dry grass, stalk and agricultural by-product,which crude fiber content more than 18%.

2.Green feed: It refers to fresh alfalfa, and vegetables, which natural moisture content more than 60%.

3.Silage: It refers to roughage, which is the green feed that was chopped and fermented.

4.Energy feed: It refers crude fiber content of less than 18%, crude protein content less than 20%.

5.Protein feed: It refers crude fiber content of less than 18%, crude protein content of more than 20%.

6.Additives: It refers to natural minerals, vitamins, antibiotics, antioxidants, etc.

The second is compound feed, it’s artificial feed. Along with the development of cultural technique and breeding technique, compound feed play an important role in modern pig farm. It can significantly reduce production costs, protein and phosphorous intake and excretion, and greenhouse gas emissions by increasing individual nutrient efficiency. We are here to talk about how to make artificial feed pellets.

Why Pig Feed Is Important?

Pigs are known for their appetites, and they have a collection of favorite foods to match. However, just like humans, pigs need a complete, well-balanced diet in order to stay well and avoid unhealthy weight gain. The nutritional needs of pigs can be divided into six categories or classes. These are water, carbohydrates, fats, proteins, vitamins and minerals. The accurate formulation makes sure the diet meets the needs of the specific pig.

Each pig with different feed Requirements, to properly nourish the pig, we need to understand its nutritional idiosyncrasies, its physiology and nutrient requirements, and how it responds to feedstuff and additive combinations. We must also realize that feeding goes beyond diet formulation, because diets must be properly processed, transported, stored, and finally presented for consumption before their potential is realized.

Good feed is necessary for growth, body maintenance and the production of meat and milk. You can use locally feeds that are less expensive, but also can be made by your own animal feed pellet mill.

Making your own pig feed is far more cost-effective than buying expensive commercial brands from the local market. In fact, if you are only raising a small pig farm, a hundred dollars' worth of homemade feed might be enough to last you a few months.

Making your own hog feed is not too difficult, as long as you know the proper ingredients and proportions to use.

When you mix and formulate your own feed, you need to know some information to help you produce high quality pig feed pellets.

Mockup Provider » Introduction of dry and wet feed pellet machines

Dry extruder

Extruder without steam conditioner, the raw material is not pre-conditioned before entering the extrusion system.

The dry type fish feed machine is as floowing.

Wet extruder

With steam conditioner, the raw material is pre-conditioned and tempered before entering the extrusion system.

Look the wet type fish feed pellet machine.

It can be seen from the definition that the most important difference between the dry and wet method is whether the material is pre-conditioned with steam before entering the extrusion. I have always understood the dry and wet method as the two working modes or modes of the extruder, rather than the essential difference in structure. From the working mode: according to whether the material is quenched and tempered by steam before entering the extruder barrel (extrusion cavity), it is divided into dry extruder and wet extruder. If it is quenched and tempered by steam, it is a wet method; otherwise, it is a dry method. 


The purpose of steam conditioning: to increase the temperature of the material, soften and partially pre-ripen the material, and add a certain amount of water. For most materials, wet puffing is more efficient than dry puffing. Considering only the temperature factor for a simple analysis, if the expected curing temperature of the material is 130 °C, the extrusion part of the dry puffing screw increases from room temperature (20 °C). To reach this value, the temperature needs to be increased by 110°C.


If wet production is used, the temperature after conditioning is 80°C, and the material temperature that needs to be raised in the screw extrusion part is 50°C. Therefore, the required mechanical energy is less than the dry method. More energy Can be used to increase production. In addition, due to the softening of the material, the wear on the screw and barrel will also be reduced.


Many users, including some equipment manufacturers, literally understand that adding water is a wet process. From the above analysis, we can know that simply adding water can not be called wet method, it just supplements part of the water, and cannot improve the temperature of the material, soften and partially pre-ripen the material.


Due to the different properties of the material entering the barrel during the production of dry/wet methods, the wet method entering the barrel is a moist and hot soft material, and the dry method entering the barrel is a raw and cold hard material. Therefore, the main system and the extrusion screw are The configuration requirements are also different.


In general, a dry process machine equipped with a steam conditioning system can be used for wet process production, and the efficiency will be improved, but it is not as efficient as the dedicated wet process model; the impact of the hard material on the shafting should be considered in the dry process of the wet process model. Dry production can be performed for some materials, but the efficiency will be reduced, and it is not suitable for some materials. In other words, a dry machine can be produced wet, while a wet machine may not necessarily be used dry.

Mockup Provider » The fish feed size of the crushed particles


Ordinary fish feed The particle size of fish feed raw materials is below 40 mesh, and the digestion and absorption rate is greatly reduced. The crushing particle size of the compound feed for juveniles of common carp, grass, green and bream should pass through 50-60 mesh (0.30mm-0.25mm), and the crushing particle size of the compound feed for adult fish should pass through a 30-40 mesh sieve. 60-0.355mm ).

Aquatic feed requires finer particle size: the requirements of aquatic products for feed are different from those of terrestrial livestock and poultry, and the crushed particle size of aquatic feed is often finer than that of livestock and poultry feed, mainly for the following reasons:

1.Digestive capacity. The digestive tract of fish and shrimp is short and thin, and the ratio of its length to its own body length is generally much smaller than that of livestock and poultry, and its digestion and absorption capacity is also weak.

At present, most of the fish, shrimp and crab species that are cultivated are carnivorous or partial carnivorous omnivorous aquatic products, and the length of their digestive tract is shorter than that of herbivorous or filter-feeding ones. In addition, fish and shrimps have weak digestion and absorption capacity for plant-based grains or cakes, and poor utilization of raw (immature) feeds. Therefore, crushing the feed finer helps to improve the utilization rate of the feed. 

2.Feeding environment. Aquatic animals eat in water, and the feed must be put into the water. Therefore, aquatic feeds are required to have a certain stability in water to keep their shape and nutrients from being lost. The smaller particle size helps to improve the water stability of the feed. At present, the common forms of aquafeed are hard pellets, extruded pellets, soft pellets and dough-like feeds. If you have a big need, you can use the diesel engine fish feed pellet machines.

For the first two forms, there is a hydrothermal quenching and tempering extrusion treatment during the processing. Small particle size, water and heat are easily transferred to the inside of the powder particles, reducing the difference in the degree of treatment between the center and the surface of the particles, which is conducive to starch gelatinization and protein denaturation in the feed ingredients.

This change process can make the difference between different powder particles. Interphase bonding, inlay, and forming stable particles under the action of extrusion. The degree of change is large, which can significantly improve the water stability of the feed. For the latter two forms, the finer powder particles will bond well with cohesive substances such as starch under the action of moisture, and the surface of the soft particles or dough will be smoother, which is beneficial to improve the stability of the feed water.

In addition, when pulverizing with a relatively fine particle size, the powder particles are also embedded with each other, which is also beneficial to the stability in water.

3. Individual size. The individuals that breed aquatic products are generally not as large as livestock and poultry, and their calibers are also small.

For the same aquatic species, the finished product is thousands of times larger than the individual seedlings. Especially for fish, shrimp and crab fry, the particle size required for crushing is correspondingly smaller.
