Cow magnets are popular with dairy farmers and veterinarians to help prevent hardware disease in their cattle. While grazing, cows eat everything from grass and dirt to nails, staples and bits of bailing wire (referred to as tramp iron). Tramp iron tends to lodge in the honeycombed walls of the reticulum, threatening the surrounding vital organs and causing irritation and inflammation, known as hardware disease. The cow loses her appetite and decreases her milk output (dairy cows), or her ability to gain weight (feeder stock). Cow magnets help prevent this disease by attracting stray metal from the folds and crevices of the rumen and reticulum. One magnet works for the life of the cow. These cow magnets also make a great addition to your science project. These magnets are powerful and are great for general experimentation with magnets. There are several kinds of cow magnets: 1) Ceramic cow magnet: This rectangular cow magnet is made of ceramic 5 (strontium ferrite) magnet material; Its special magnetization pattern causes nails and other sharp metal objects to line up along the length of the magnet where they are no longer a danger to the cow; The FDA-approved epoxy coating is gentle on the cow and helps protect the magnet from chipping; Rounded corners ensure safe and easy passage to the reticulum2) AlNiCo 5 cow magnet: A favorite of dairymen and vets for over 30 years; This is the standard cast AlNiCo cow magnet with bright, metal finish; It is non-toxic and non-corrosive in use
Qingshui fish (grass carp, squid, squid, etc.) is a kind of aquatic product with unique flavor and quality, which is produced by using pure, natural green plants as the feed in the natural environment of mountainous areas, using clear, perennial springs and streams. Qingshui fish is favored by people for its unique breeding methods, unique nutritional value and delicious flavor. 1 Aquaculture environmental conditions The natural ecological environment of clean water fish farming should be clean, fine, free of any pollution, rich in water sources, and ensure continuous water flow for many years. Other health indicators are better than the national standard "No pollution food freshwater aquaculture water quality standards." 2 The construction of ponds and fish ponds will be built in the construction of ponds and ponds, beaches, lands and places where light is long. According to the terrain conditions, it is appropriate to excavate rectangular, square or other shaped ponds. The area of ​​fish ponds depends on the size of the water flow and is generally within 10 to 50 square meters. If the area is too large, the whole pool of water is not easy to flow and it is unfavorable for farming. The depth of the pond is based on the self-discharge of water and the water depth of 0.7-1.0 meters. Tanggu is built with stones or cement, generally without slopes. The height should be more than 0.5 meters above the high water level. The bottom of the pond is laid with small pebbles, sand or stones, and the hard bottom is easy to clean. In the upper part of the pond, some shady scaffolds are needed to be built. In the season, some fruits and plants are planted on the scaffolds, which will help cool the sun in the summer. The location of the water inlet at Tangjiao is the same as or higher than the high water level, and the water outlet is located at the bottom to facilitate drainage and management of future discharge. Inlet and outlet also need to set a fish bar, both anti-fish escape, but also block floating debris. 3 Fish breeding stocks should be cleaned and disinfected 15 days before stocking. For each square meter of fish ponds, 0.3 kg of quicklime or 20 grams of bleaching powder is poured on the whole pond. After 2-3 days, the pool water is drained, and it is exposed to water for about 10 days. Qingshui fish stocking mainly grass carp, a small amount of carp, carp, Qing fish. Restocking time starts after the beginning of each year and around the Spring Festival. Fish species specifications require a body length of 15 cm or more, and a one-year-old grass carp weighs about 250 grams. Stocking densities are generally about 10-13 tails per square meter of grass carp. Before stocking, the fingerlings must be soaked in a bath for 15-20 minutes with 3% salt solution before the lower pond. 4 The “Sanding†feed for clear water fish is mainly based on natural or artificially grown green feed, supplemented with other bud feeds such as grain buds and malt, and not fed any compound feed. Timing: 2 times a day, 8:00- 9:00 am, 3:00-4:00 pm each; Qualitative: green feed fresh, delicate, non-polluting, other feed fresh; quantitative: eat eight full of fish Prevail, that is, the feed is eaten by the fish in about 3 hours. 5 Adjusting water flow regulation is an important measure for clearwater fish farming and management under small area and high density conditions. In principle, the size of the flow can be controlled according to the season. Spring: After the wintering of the fish, the physical strength is poor, and the fish species need to adapt to the flow from the still water to the flowing water environment. Therefore, it is necessary to live in slow-flowing water for a period of time. Pool water exchange is generally controlled 1-2 times a day. Summer: It is a season of long fish, with a large amount of oxygen. The amount of water exchanged in the pool is 3 to 5 times per day. Fall: To properly control the amount of water flow, the exchange of pool water is about 2-3 times a day, so that the body strength will not be consumed excessively, and it will be beneficial to winter. In winter: The water temperature is low, the fish activity is small, the metabolism is slow, micro-flowing water is given, and the amount of pool water exchange can be about once every day and night.
