In the diets fed with fishes and adults, the proportion of rare earths can not only improve the feed utilization rate, but also promote its growth, enhance disease resistance, play a role in preventing disease, reduce death, and increase economic efficiency.
First, the use of concentrate feeds to feed fish is mainly conducive to the breeding of fish. The preparation method is to dissolve rare earth 40g-50g or rare earth additive 1 package with a little vinegar or acid water, and then mix with 0.5kg of water and spray evenly on 60kg of fine feed with a sprayer, spray and mix, if possible Made of extruded feed, the effect is more ideal.
Second, with the green feed fed into the fish with a concentration of 300ppm of rare earth, in the grass before harvest 10 days, evenly sprayed on the grass, the amount of 50 acres generally. It can increase the amount of fresh grass by 7% ~ 9%, while reducing the loss of rare earth due to water dissolution. Can also be used on the same day with rare earth additives 2 packages, spray on the grass, until the water is dry, you can cut feeding. Can also be first cut grass, let the sun a sun, and then use rare earth 40 grams plus rare earth additives for fish 1 package, watered 20 kg, sprayed on 300 kg to 400 kg of green fodder, then fed.
Third, the matters needing attention 1. Select sunny feeding, rainy days should not be fed. 2. Feed at 5 pm to 7 pm, because this time is a period of high fish consumption. 3. First improve the water quality, after feeding fish. If the water quality is good, it can be fed immediately. If the water is turbid and smelly, fresh water should be replaced before feeding. 4. Disinfected fish ponds work better. In the fry under the pond before the mu, 150 grams of rare earth or 3 packets of rare earth additives plus 250 grams of salt, watered 50 kg, dubbed rare earth solution, sprinkled in the pond, fry 5 minutes later.
