In a livestock feed production line, pellet size is one of the most important technical parameters because it directly influences feed intake, digestion, animal growth performance, and feeding efficiency. The pellet dimensions are mainly defined by the pellet mill die and can be adjusted according to different livestock species and growth stages.
Pellet diameter in a livestock feed production line commonly ranges from 2.5 mm to 8.0 mm. Smaller pellet sizes, usually between 2.5 mm and 3.0 mm, are mainly used for young livestock such as piglets or calves at the starter stage. These smaller pellets are easier to chew and digest, helping young animals adapt quickly to pelleted feed.
Pellets with a diameter of 3.0 mm to 4.0 mm are widely used for growing pigs and small ruminants. This size offers a good balance between feed intake speed and nutrient absorption and is one of the most commonly applied specifications in livestock feed production lines.
For finishing pigs, sheep, goats, and beef cattle, pellet diameters of 4.0 mm to 5.0 mm are commonly selected. Larger pellets reduce dust generation during feeding and transport, improve feed durability, and support efficient feeding in medium to large-scale livestock farms.
In large ruminant feeding systems, especially for adult cattle in feedlots, pellet sizes of 6.0 mm to 8.0 mm are often used. These pellets have higher mechanical strength and are suitable for bulk handling, storage, and long-distance transportation.
Pellet length in a livestock feed production line is typically adjustable and generally controlled within a range of 5 mm to 25 mm by the cutting knives installed at the pellet mill outlet. Shorter pellets help reduce feed waste, while medium-length pellets are preferred for most livestock feeding applications.
Overall, selecting the correct pellet size in a livestock feed production line ensures better feed utilization, stable animal performance, and efficient long-term operation of the production system.
