Detailed Introduction to the Physiological Characteristics of Finishing Pigs

  (One) Stage Division of the Physiological Characteristics of Finishing Pigs

  According to the physiological characteristics of finishing pigs, their growth process is generally divided into two stages: 25-60 kg is the early finishing stage; 60-100 kg is the late finishing stage.

  (Two) Physiological Characteristics of Finishing Pigs

  In pigs weighing more than 25 kg, although their growth and development are at a vigorous stage, their digestive system is still not fully developed, and certain effective components in the digestive juices are insufficient, which affects the absorption of nutrients in some feeds, and the stomach volume is still small, so it cannot hold a relatively large amount of food at one time. The nervous system and the body's resistance are also at a stage of gradual improvement. Therefore, high-quality feed that is easy to digest and absorb should be provided, and management should be strengthened to improve the feeding environment.

  After body weight reaches 60 kg, physiological functions gradually improve, the digestive system develops greatly, and the ability to digest various substances and absorb various nutrients in feed is greatly improved. The nervous system and the body's resistance to various external stimuli are also greatly enhanced and more fully developed, and adaptability to the surrounding environment is also greater. Growth speed is fastest during this period, so the opportunity for rapid fattening should be seized, and high-quality compound feed that meets the growth needs of finishing pigs should be provided in a timely manner, so as to give full play to the pigs' advantage of fast growth and achieve the goals of rapid weight gain, a high slaughter rate, high feed utilization, lower costs, and increased economic benefits.
