How to increase the feed intake of lactating sows?
Reduce feed intake during sows during pregnancy.
From the day of delivery, the lactating sows are fed a sufficient amount of fresh feed every day.
The temperature in the delivery room is maintained at about 18 to 20 ° C, the temperature is low, and the sow consumes more feed.
Allow the sow to freely feed the wet mix or pellet feed and clean the trough regularly.
Provide sufficient water for the sow, and the water flow rate of the drinker is 1.5 l / min.
High Temperature Alloy is divided into three kinds of material: 760 ℃ high-temperature material, 1200℃ high temperature and 1500 ℃ high temperature materials, the tensile strength is 800 mpa. On other words,it refers to the metal material worked well in the condition of 760-1500 ℃ or above. It owns excellent high temperature strength, good resistance to oxidation and thermal corrosion resistance, good fatigue properties, fracture toughness and other comprehensive performance, this kind of material has became an irreplaceable key material in military and civilian gas turbine engine hot end components . According to the relevant theory, 760 ℃ high-temperature materials, according to the matrix elements,can be mainly divided into high temperature iron base alloy, nickel base superalloy and cobalt-based super alloy. According to the preparation process,it can be divided into deformation and high temperature alloy, casting high temperature alloy and powder metallurgy super alloy. According to the solid methods,it can be divided into solid solution strengthening, precipitation strengthening and oxide dispersion strengthened with fiber reinforced type, etc.
