1 Feed source
Astragalus food complex. For animal feeds, sources can be sourced from multiple sources. The first is to apply base fertilizer in aquaculture ponds. Cultivate cladocera, copepods, rotifers and benthic animals, etc.; secondly, raise some spawning squid in the rearing pond and hold egg-shrimps to let them spawn and hatch out larvae; thirdly, specialize in breeding of snails or snails, and river clams. Etc.; can also be combined with the development of pearl farming, the use of oyster meat as a bait; Fourth, in the breeding pool on the black light hung to trap moths, roundworms and other insects; Fifth, the use of pigs, sheep, geese, ducks of the internal organs; Sixth, nurturing or digging maggots, fishing for fly maggots, etc.; seventh, when animal foods are insufficient, they can feed rice, noodles, melon husks and other plant feeds.
2 feeding technology
Astragalus feeding should adhere to the "four principles" principle: First, set the quality, do not feed rancid feed, to ensure fresh feed does not deteriorate; Second, quantitative, Astragalus ingestion intensity is directly related to the water temperature, usually 4-5 month feed amount It is 3% of body weight; from August to August, the intensity of ingestion of Astragalus membranaceus is the highest and the growth is fastest. The daily feeding amount can be increased to 8%-10% of the body weight; when the temperature reaches 30Â°C or above, it should be less or not. . Generally should be checked 1 hour after feeding, if the bait has been eaten, indicating that the amount of bait is insufficient, should be increased appropriately, if not finished within 1 hour, then the bait overdose, should be appropriate reductions; third is the timing, according to Astragalus has Nocturnal habits, feeding two times a day, feeding at 10 o'clock in the morning and 6 o'clock in the afternoon, feeding in the afternoon; four is positioning, in order to make the astragalus cultivate the habit of eating at a fixed point, easy to observe In case of eating conditions and cleaning up the remnants, the food station should be set up, and the food should be provided at a fixed place. The food table is the place where the Huang Qi Qun competes for food. The food table should be properly dispersed and several more should be set up.
It is necessary to point out that the seedlings of the currently cultivated Astragalus are mainly collected from the wild and are not adapted to the environment at the time of initial stocking. Generally, they do not eat artificially fed feed and therefore need to be fed, otherwise they may easily lead to loss of appetite. Breeding failed. The specific method of taming is: broiler species will not be fed within 3 to 4 days of feeding, so that the abdominal foods will be digested, then the pool water will be let off and fresh water will be introduced in the evening. When priming, chop and minced meat are best chopped with scallops and oysters eaten by Astragalus. They are placed on the side of the inlet in several small piles and properly filled with water to cause micro-flow. The first feeding amount is 1% - 2% of the weight of the quail species. If all the food is consumed in the morning of the second day, the feeding amount can be increased to 2% - 3%. If the feed on the day cannot be finished, the residual material should be removed and the feed should be fed on the first day after the first day of production. After the food is normal, the source of melon peel and bean cake can be easily mixed into the feed. Wait 1/5 for the first time and reduce 1/5 of the feed intake. If you eat properly, add 1/5 of the normal feed daily. After a few days, feed it normally.
