The present invention provides a water tank system for breeding ornamental fish and coral reefs and a method for establishing the same. The coral reef system comprises a breeding tank (1), a purified water pipeline (12), a gas pipeline (13), a filter element (14), a water quality filter box (2), an artificial light source (3) and a pumping system (4). The breeding tank (1) is connected to the water quality filter box (2) and the pumping system (4), and the water quality filter box (2) is connected to the pumping system (4). A gravel layer is laid in the breeding tank (1), and a trapezoidal frame is placed on the gravel layer. One side of the trapezoidal frame is placed on the gravel layer, and the upper and lower sides are grid hollow structures. The filter element comprises activated carbon, zeolite and phosphate rock powder. The corals obtained by the invention have good growth conditions, with bud length of 38.62-39.27 mm, bud height of 37.02-38.45 mm, and mass of 43.6-45.0 g. A water tank system suitable for ornamental fish breeding and coral reef cultivation is established, which can achieve a breeding environment close to nature, enable the corals to reproduce and grow normally, and achieve good growth quality.

This invention relates to the field of fish fry breeding and aquaculture technology, and specifically discloses a feeding device for breeding and aquaculture of Schizothorax bream fry, comprising: a frame, with support rods fixedly connected to the outer side of the frame, a buoyancy ball fixedly connected to the end of the support rods away from the frame via a bracket, a feed storage box fixedly connected to the top of the frame, a feeding port on the top of the feed storage box, and a discharge frame connected to the bottom of the feed storage box; a feeding device, the top of which is fixedly connected to the outer side of the frame; and a diffusion device, the outer side of which is fixedly connected to the outer side of the frame via a bracket; multiple sets of support rods are provided, evenly distributed on the outer side of the frame; wherein, the feeding device includes a feeding roller. This feeding device for breeding and aquaculture of Schizothorax bream fry can distribute a fixed amount of feed into the breeding pond and can adjust the feeding amount.

This invention relates to the field of animal feed technology, specifically to a herbivore feed and its preparation method. The herbivore feed includes silage, wheat straw, corn flour, brewer's grains, beet pulp, wrapped corn silage, and soybean meal; the silage includes dried apple pomace, wheat straw, and hybrid Napier grass. The preparation method of this herbivore feed is simple. Adding dried apple pomace to the silage to adjust moisture content helps increase the reducing sugar content of the silage, thereby increasing foraging activity in ruminants in southern pastoral areas, mitigating heat stress in ruminants during summer, maintaining stable milk production in dairy cows, and increasing economic benefits.

The invention discloses a feeder cattle fattening method, nano zinc oxide and active anion hydrogen water are used for feeder cattle breeding, and the feeder cattle breeding method comprises the steps that 1, feeder cattle are fed with coarse feed and concentrated feed; (2) carrying out spraying management by using a nano zinc oxide solution; (3) drinking water management; the breeding method can promote growth and development of the feeder cattle, prevent diseases, protect gastrointestinal health, improve resistance of the feeder cattle and improve slaughtering rate of the feeder cattle, use of antibiotics and drugs is replaced, fishy flavor of products caused by long-term feeding of the antibiotics is avoided, antibiotic-free and veterinary-drug-free breeding is achieved, daily average weight gain can reach 2-3 kg, and the breeding cost is reduced. The slaughtering period is shortened to 4-6 months, so that the feeder cattle can be slaughtered in advance, and the breeding cost is saved.
