Clever use of cow dung to feed pigs According to the determination, dry cow dung contains crude protein 10% - 20%, crude fat 1% - 3%, nitrogen-free extract 20% - 30%, crude fiber 15% -30 %, it is a kind of good nutrition, so long as it is used, it can turn waste into treasure. This is mainly because cattle are ruminants. The feed that is eaten is fermented and decomposed by rumen microbes of cattle, and some nutrients are absorbed and used. Part of the nutrient can be used by monogastric animal protein nitrogen, microorganisms and rumen fluid is excreted. Therefore, it has a certain feed value. However, pigs cannot be fed with raw cow dung, and it is best to ferment the cow dung in silage. The method comprises the following steps: mixing cow dung with gluten, bran and other feeds, adding appropriate amount of gold bait feed fermenting agent into a cellar, a cylinder or a plastic bag in a compacted closed industry for fermentation. The fermented cow dung has good palatability and can replace some of the other feeds. Pigs gain more weight after eating. In the amount of cow dung, pigs and piglets are generally unsuitable to use cow dung, and the amount of fat in the finishing pig diet should be 10%-15%. There are more crude fibres in cow dung, so it is necessary to gradually increase the amount of feed and it is not advisable to add too much.
Laboratory ovens are ovens for high-forced volume thermal convection applications. These ovens generally provide uniform temperatures throughout. Process applications for laboratory ovens can be for annealing, die-bond curing, drying, Polyimide baking, sterilizing, and other industrial laboratory functions. Typical sizes are from one cubic foot to 0.9 cubic metres (32 cu ft) with temperatures that can be over 340 degrees Celsius.
Laboratory ovens can be used in numerous different applications and configurations, including clean rooms, forced convection, horizontal airflow, inert atmosphere, natural convection, and pass through.
Some of the types of industries that typically use these laboratory ovens are the healthcare industry, technology industry, and transportation industry. Civil engineering laboratories uses ovens for drying asphalt, soil, rock, or concrete samples.
