How to Formulate Pig Feed Ingredients
A Reasonable Selection of Raw Materials
The first and most important step in how to make pig food is choosing raw materials.
Pay attention to the quantity of raw materials. To ensure that pigs have access to the nutrients they need every day, the raw materials should be equal in volume and volume. The pig will not be able to eat the required amount of feed if it is too large. This will not only cause nutritional deficiencies but also increase the strain on the digestive system. Pigs who feel irritable, even though they have all the nutrients, will experience a decrease in growth and development.
Second, it should be based upon local conditions and the principle of local material, making maximum use of local raw materials resources.
Third, pay attention to the characteristics and composition of feed ingredients. You need to understand the characteristics of the raw materials. For example, palatability and the content of harmful and toxic ingredients in feed, as well as feed pollution and mold. It is important that you limit the use of toxic raw materials.
Fourth, pay attention to the amount and type of raw materials.
Diversifying raw materials is important to ensure that there are many nutritional complementarities among them. Commonly used in pig feed ingredients like corn, rice and barley, wheat and sorghum. Bran such as rice bran, wheat bran, and others accounted for 5O% to 7%. Soybean cake, soybean meal, and soybean cake accounted respectively for lO%2O%, animal protein feeds such as fish meal, pupae, pupae, and grass meal less than 5%; shell powder or stone powder accounted respectively for 3%3.5%, bone meal accounted 2%2.5%, and salt less than O.5%.
Making Pig Feed Pellets in 5 Steps
The First Step Crushing Process
Crushing is suitable for crushing raw materials into powders with the best particle size to obtain the best granulation effect.
The Second Step Mixing Process
In the process of making pig feed pellets, a feed mixer can be used to fully mix various raw materials and ensure the nutritional balance of each bite of finished feed pellets. If you don’t want to make your own pig feed pellets, you can use a mixer to mix your own pig feed after crushing the ingredients.
The Key Step Pelletizing Process
Feed granule machine is the main equipment for making pig feed pellet. Compared with flat mold pig feed machine, the production capacity of ring mold pig feed production machine is larger.
The Fourth Step Cooling Process
During the cooling and screening process, particles from the pig feed machine can be discharged at up to 88℃ and 17-18% moisture. The temperature of the particles must be reduced rapidly to achieve a moisture content of 10-12% or less for proper storage and handling. Therefore, the final pig feed pellets must be cooled and dried. Our particle cooler adopts the principle of countercurrent cooling, and the particles are fully and evenly cooled. The particle temperature after cooling should not be higher than room temperature +3-5 degrees.
The Last Step Packaging Process
The cooled particles will be bagged or stored according to your needs and requirements. The packing process is effectively handled by our semi-automatic packing machine. The finished feed is weighed by computer and then unloaded into bags by air. The weighed bags will be driven along a conveyor belt and the machine can be used to sew the top of the bag where the dry feed can be stored.
Types Of Pig Feed
1. Energy Type Pig Feed
Energy type pig feed has a lower crude fiber content of 18% and a lower crude protein content in dry matter. It has high energy and less crude fiber. It also has good palatability. Energy type pig feed ingredients are grain feed, bran food, barley, corn and sorghum. They also include wheat bran (barley bran), barnyard bran and wheat bran.
2. Roughage Type Pig Feed
Air-dried feeds generally have lower nutritional values than other feeds. The roughage type pig feed ingredients include straw, leaves and grass flour, as well as agricultural by-products and leaf leaves.
3. Protein Type Pig Feed
Protein type pig feeds are low in natural water and have a higher protein content than 20%. They can be made from animal- or plant-based protein feeds. Protein pig feed ingredients include plant-based protein feeds such as soybean, peanut, and rapeseed cakes. Cicada pupae are animal protein feeds. They include fish and shrimp meal as well as meat meal, milk products, and dairy products.
4. Mineral Type Pig Feed
Mineral pig feeds are a supplement to pigs that contain essential nutrients. They can be added in the appropriate amounts. Minerals such as copper sulfate (table salt), potassium iodide and ferrous sulfate are all part of mineral pig feed ingredients. All types of vitamins A, D, and other nutrients that can help the pig’s metabolic process work more efficiently.
Ingredients For Pig Feed Formulation For Different Stage
Pig growth and development is based on feed. Each component of pig feed has a different nutritional value. Therefore, it is important to scientifically adjust the feed according to the pig’s growth stage. Vitamins and minerals should also be added. The best pig feed recipe is usually based on the weights of the pigs.
1. Pig Feed Recipe for Small Pigs (About 10-20 Kilograms)
Corn meal 57%; soybean meal 20%; fish meal 5%; rice bran or white bran 15%; calcium hydrogen phosphate 11%, shellac 0.5% and salt 0.35%. Premix 1% (containing trace elements. vitamins., etc. .
This pig feed formula contains 3230 calories/kg digestible energy, 18.4% raw protein, 3.5% crude fibre, and 0.682% phosphorus. It is an extremely standard piglet nutrition formula.
2. Pig Feed Formulation for Large Pigs (About 60 to 90 Kg or More)
Soybean meal 70%, corn meal 15%, rice bran, wheat bran 12% and calcium hydrogen phosphate 1.0%. Shellac 0.8%. Salt 0.35%. Premix (containing trace elements, vitamins, and non-nutritive additives, etc. 1%.
This feed formula is suitable for large pigs. It contains 14% crude protein and 3240 calories/kg digestible energies. 3.7% crude fiber. 0.65% Lysine. However, the lysine content is less than 0.633%. Climate warming and flooding have all contributed to the increase in mold growth in recent years. Food and feed storage as well as transportation will lead to increased mycotoxin production. This directly affects the health of poultry and livestock.
3. Pig Feed Formula for Medium-Sized Pigs (About20-60 Kg).
Corn meal 62%; soybean meal 20%; rice bran or white bran 15%; calcium hydrogen phosphate 1.2%; shellac 0.8%; salt 0.35%. Premix 1% (containing trace elements and vitamins, as well as non-nutritive additives, etc. .
This pig feed formula contains 16% crude protein and 3180 calories/kg digestible energies. It also has 3.8% crude fiber and 0.656% calcium. The phosphorus content is 0.577%, 0.747% lysine. This is a fairly standard nutritional formula for medium-sized pork feed. The lysine content was lower than the 0.75% requirement due to the elimination of fish meal. However, this correlation isn’t significant and can be ignored.
Attention To Preparing Ingredients For Pig Feed Formulation
- You must be aware of the relationship between the feed quantity and the intake of pigs when you make pig feed recipes. The feed should not be too large. If it is too small, the pig will have a limited gastrointestinal volume and may not be able eat the feed. This can cause the feed to not absorb the nutrients properly. If the feed is not sufficient, it can also reduce the feed’s utilization rate.
- You should consider several principles when preparing ingredients for pig feed formulation. These include nutritionally comprehensive, control of crude fiber content, and whether the feed volume will be appropriate. To make the protein, amino acids, energy, vitamins, and minerals nutritionally complete, Feed must meet specific feeding standards. You must ensure that your pigs are able to eat a variety of nutritious feeds to increase their nutritional value.
