Oxidation of oil in pigs is 100 times more energy than equivalent carbohydrates. It can meet the higher energy needs of pigs and reduce the conversion of amino acids into protein. Grease can provide the necessary unsaturated fatty acids for pigs to ensure the healthy growth of pigs. It can improve feed palatability and increase feed intake of pigs; it can reduce feed dust and reduce the occurrence of porcine respiratory diseases. Oil addition technology The fragrant seasoning such as lard, butter, soybean oil, peanut oil, ginger, etc. is fried and flaked until the fat cools and is directly added to the feed; or the flour is added to the flour, cornmeal, flour mill, and a certain amount of Antioxidants (such as vitamin E, etc.), Stir well, dry or dried, add comminuted pigs to the feed. Adding amount and effect of grease Adding 3% fat to the 2-4 week old piglet diet increases weight gain by 10% to 14%, reduces mortality by 30% to 50%, and reduces weaning stress. Add 4%-5% fat to fattening pig diets, increase weight gain by 12%-15%, increase weight by 1 kg, reduce feed consumption by 8%-10%, reduce fattening days by 15-20 days, slaughter After the carcass fat is white and firm, the muscles are of bright color, and the grade of pork products can be improved. Pigs pay attention to grease The rancid, contaminated fats cannot be fed to pigs, otherwise the health of the pigs will be affected. When strictly controlling the oils, attention should be paid to the supply of choline chloride. 0.05% of feed should be added to prevent the occurrence of fatty liver; fats should be fed to pigs from small amounts Gradually transition to the right amount, otherwise prone to digestive disorders.
The water meters are the
most popular used meters and have very long history of development. Water
meters are mainly measuring the total flow for the water consumption. From many
years of growing and development, from the very simple water meters,residential water meter,cold water meter, electronic
water meters, Mechanical Water Meters, Ultrasonic Water Meters, smart water
meters to the wireless water meters, people cares much more about the water
meters accuracy and energy saving. Our company concentrates on the development
of the mechanical water meters and ultrasonic water meters for many years.
Our mechanical water
meters are mainly with the accuracy class 3 and our ultrasonic water meters are
with the accuracy class 2. Now our company is still developing the water meters
with higher level accuracy. Comparing with the traditional simple water meters,
our water meters strengthen the advantages of water saving, higher accuracy,
easy installation and long lifetime use. Usually speaking, our water meters
have more than 5 years quality guarantee. Meanwhile, low cost maintenance is
also very good advantages of our water meters.
