How to Skillfully Master the Pig Feed-to-Water Ratio? A Must-Read for Pig Farmers
Mixing pig feed with too much water and making it too thin is a long-standing habit among rural people. It has many drawbacks: First, when the feed is mixed too thin, the water content in the daily ration increases relatively, the nutritional components are insufficient, saliva secretion is greatly reduced, the gastric juice is diluted, and the feed stays in the stomach for a shorter time, severely reducing the feed's utilization rate. Second, it increases the physiological burden and raises the body's heat consumption. In addition, in autumn and winter, because pigs urinate more, the pigpen becomes damp and cold, seriously affecting the pigs' growth, development and health. It can thus be seen that pig feed is better prepared as a moist mash, which not only saves
