Why Use Feed Pellets for Cattle Farming?
Optimize Feed Digestibility and Improve Breeding Efficiency
The high temperature and high pressure conditioning process in the feed granulation process can promote the starch in the feed to fully gelatinize, destroy the anti-nutritional factors in the raw materials, soften the crude fiber structure, better adapt to the rumen digestion mechanism of cattle, and greatly improve the overall digestion and utilization rate of the feed. Compared with traditional bulk feeding, pellet feed can effectively improve feed conversion rate, accelerate calf growth rate, improve weight gain efficiency of beef cattle, improve milk yield and milk quality of dairy cows, and comprehensively improve breeding economic benefits from growth and production dimensions.
Enhance Feed Storage and Feeding Safety
The high temperature treatment in the granulation process can effectively kill harmful microorganisms such as Escherichia coli and mold in the feed, and reduce the risk of mildew and germ breeding in the feed. The formed pellet feed has a firm structure and is not prone to moisture, agglomeration, and delamination. Compared with loose powder, it can effectively avoid problems such as nutrient loss, insect infestation, and mildew during storage, and greatly extend the feed storage cycle. Stable feed quality can reduce gastrointestinal diseases, mildew poisoning and other problems of cattle, reduce the risk of breeding diseases, and ensure the healthy growth of cattle.
Flexible Feed Formulation to Meet Diverse Breeding Needs
Using pellet machine to make cattle feed, farmers can rely on local crop straw, agricultural and sideline products, grain and oil processing scraps and other raw materials to independently prepare feed formula, without relying on commercial finished feed. It can not only adjust the nutrition ratio according to different breeding categories and growth stages of dairy cows, beef cattle, calves and fattening cattle, accurately match the breeding needs, but also maximize the use of local cheap raw materials, reduce the cost of feed procurement, and realize low-cost and customized breeding. It should be noted that pellet feed can not completely replace coarse feed, and proper amount of forage and straw should still be matched in the breeding process to ensure the rumen health of cattle.
What Ingredients Are Used to Make Cattle Feed Pellets?
Energy Feed Raw Materials
Energy raw material is the core component of cattle feed, accounting for 20%-60% of pellet feed formula, mainly for herd growth, lactation, daily activities to provide carbohydrates and energy, directly determine the herd growth rate and production performance. Common energy raw materials are corn, wheat, barley, sorghum, oat and other grains, among which corn has the widest applicability and the highest energy conversion rate, which is the mainstream core raw material. At the same time, rice bran, wheat bran and other agricultural and sideline products can also be used as auxiliary energy raw materials, which can not only supplement energy, but also add a small amount of protein and crude fiber to enrich the nutritional structure of feed.
Protein Feed Raw Materials
Protein raw material is the core nutrition of cattle muscle growth, milk synthesis and immune repair, and is an indispensable component in feed ratio. In breeding, priority is given to the use of more cost-effective vegetable protein raw materials, including soybean meal, cottonseed cake, peanut cake, rapeseed meal, sunflower seed meal and other oil processing leftovers. Among them, soybean meal has high protein content and stable quality, and is a universal high-quality protein raw material. In some high-end breeding scenarios, a small amount of animal protein such as fish meal can be added, and at the same time, non-protein nitrogen raw materials such as urea can be added in an appropriate amount to supplement nitrogen elements for ruminants. The dosage shall be strictly controlled to avoid exceeding the standard and causing diseases.
Coarse Fiber Forage Raw Materials
As ruminants, cattle crude fiber is the core nutrition to maintain rumen motility and digestive function, which is indispensable. Crude fiber raw materials mainly include alfalfa, grass, hay and other high-quality forage grass, as well as wheat straw, corn straw, straw, peanut seedlings and other crop residues. At the same time, beet residue, soybean hull, cottonseed hull and other auxiliary materials can also be used as crude fiber sources, which can not only improve the crude fiber content of feed, ensure rumen health, but also enhance the particle molding degree and improve the storage resistance of feed. The proportion of high fiber raw materials is controlled at 10%-20%, which is suitable for the digestive physiological characteristics of cattle.
How to Make Cattle Feed Pellets with a Pellet Mill?
Raw Material Screening and Pretreatment
The first step of feed processing is raw material screening and pretreatment to ensure the quality of pellet feed from the source. First, strictly screen all kinds of raw materials, remove moldy, rotten and deteriorated raw materials, remove stones, metal impurities, sediment and other foreign matters in raw materials through sieve and magnet equipment, so as to avoid damaging equipment and affecting feed safety. For straw, hay, peanut seedlings and other long roughage, it is necessary to chop it into 1-2cm pieces in advance for subsequent crushing and processing. At the same time, the moisture content of raw materials shall be controlled. Wet raw materials shall be dried in advance to prevent mildew during processing and storage, laying a foundation for subsequent procedures.
Crushing and Refining of Raw Materials
All kinds of raw materials after pretreatment are put into a hammer mill for grinding and processing, and the particle size of raw materials is controlled within 3-4 mm. Refining the particle size of raw materials can improve the stirring uniformity, particle molding degree and feed digestibility. In the process of crushing, it is necessary to distinguish the types of raw materials. Grain and concentrate raw materials shall be crushed more finely. The particle size of coarse fiber raw materials such as straw and forage grass shall be relaxed appropriately to avoid excessive crushing and excessive dust. Raw material crushing too coarse will lead to loose particles, easy to break, too fine dust, particles too hard, affecting herd intake and digestion, need to strictly control crushing standards.
Precision Mixing
All the crushed raw materials, additives and liquid auxiliary materials are uniformly put into a feed mixer for 5-10 minutes to be fully stirred to realize uniform distribution of nutrient components. The mixing process should follow the principle of first solid, then liquid, first mix grain, cake, crude fiber raw materials, dry powder additives, and then slowly spray molasses, water and other liquid materials to ensure that each mixture has the same nutritional ratio. Small-scale breeding scenarios can be manually assisted with stirring, and large-scale production relies on professional mixers to greatly improve mixing accuracy and efficiency and avoid local nutrient imbalance.
Feed Conditioning Optimization
Conditioning is a key process to improve the quality of pellet feed, which is necessary for large-scale production. Small equipment can simplify operation. Through steam heating and spray humidification, the temperature of the mixture is raised to 70-90 °C, and the moisture content is adjusted to 15%-18%. High temperature and humidity environment can promote starch gelatinization, strengthen raw material cohesion, make particles more compact and durable, kill harmful bacteria in raw materials, soften crude fiber, improve feed digestion and utilization rate. Small flat-mold pellet machine does not need professional steam conditioning, can adjust humidity by adding water, molasses, relying on the heat generated by equipment extrusion friction to complete simple conditioning.
High-Pressure Pelletizing
The mixture after conditioning is put into the hopper of the granulator at a constant speed, and the equipment is started to complete the granulation molding. The continuous pressure of the press roller forces the mixture through the die holes to form strips of feed, which are then cut into standard length pellets by custom cutters. During the processing, the mold should be changed according to the herd type, and the calf should use 3-4mm mold hole, and the adult cow should use 6-8mm mold hole. At the same time, control the feeding speed to avoid overload of the equipment and ensure uniform particle density and length. The temperature of the newly formed particles can reach 80-90 °C, and the texture is soft, belonging to the normal processing state.
Pellet Cooling and Drying
High temperature molding particles have high moisture content, soft texture, and are easy to mold and agglomerate when stored directly, so cooling and drying is an essential process. The large-scale production line uses a counter-flow cooler, which can cool the particles to normal temperature in about 10 minutes and reduce the moisture content to 13%-14% of the safe storage standard. In the small-scale breeding scene, the particles can be evenly spread, naturally ventilated and cooled, and the hardness of the fully dried particles reaches the standard and the structure is stable, which can effectively avoid deterioration and damage during storage.
Screening, Grading, Storage and Packaging
The cooled particles are screened by vibrating screen to remove dust, broken particles and residual particles. The screened broken materials and dust can be recycled and processed again to avoid waste of raw materials. For calf breeding needs, large pellet feed can be crushed into fine pellets, suitable for calf intake. Finally, the finished particles are bagged and sealed according to the specification of 25-50kg, marked with formula and production date, stored in a cool and dry place, or directly stored in bulk to complete the whole processing flow.
