First, the use of rubbing brick 1. Place the loquat block on the spot where the cows are convenient to feed, and ensure sufficient drinking water. The loquat block is very hard and is not afraid of high temperature, rain, cold, and the calf bite. There is no waste in use. 2, free foraging behavior can effectively promote the secretion of saliva, promote food digestion, improve feed utilization, saving fine material. 3. To help cattle relieve the unpleasant stimuli brought about by the feeding environment, feed changes and seasonal temperature changes, reduce the prevalence rate, and improve the body's immunity and production capacity. Second, the effect of rubbing brick 1. Balanced and rich nutrition formula, magnesium, iron, cobalt, copper, manganese, zinc, selenium, sodium and other elements interact to participate in animal metabolism to ensure the rapid growth of livestock and overall health. 2, according to the characteristics and needs of cattle, developed a special reel brick for cattle, the results of the use of reckless brick cattle and sheep, no longer smashing the wall, but like the reel brick. In the growth, fur appearance, fatness, health, and output have been greatly improved, so burdock bricks are very popular in beef cattle breeding. Because its effect is considerable. Breeding cattle with tanning bricks saves time and effort, and can increase labor productivity and reduce production costs. At the same time, it makes up for the lack of nutrients in the natural pasture and straw feeds, thereby improving feed utilization. Dynamic 9D LADAR is a breakthrough technology, representing the fastest, most accurate non-contact measurement system in the world. 9D LADAR`s rapid, accurate data collection in real-time is set to revolutionize automated in-line production measurements and obsolete exiting conventional Laser Radar systems that require large sample averaging to obtain reasonable accuracy, effectively slowing data acquisition rates.
