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
Grass grows geese to feed fish fertilizer field to increase production gains
Jiangsu Jintan Agricultural Bureau, Meteorological Bureau, Jiang Zuming, Sun Heping, Shi Jinyu, Ren Linyong, Zhang Qinghua, Lu Lianqing, Zhang Genglin, Xu Ying, Zhuan Xiaoye, Zhuo Xiaoxiao, a professional household in the township of Jintan, Jiangsu, China, and Tian Weiye from 120-mu farmland contracted from 1996-1999. 50 acres of land were allocated. In the autumn, wheat and rapeseed were not planted, only feed (rye grass) was planted, and a multi-structure of grass-goose (fish)-one rice cultivation was carried out, and remarkable results were achieved. In the past few years, the net profit per acre in winter agriculture has increased by 508.80-587.20 yuan, and the ecological environment of farmland has also been improved. One, grass cultivation, tune the structure of grass cultivation is autumn grass, winter and spring goose (fish), summer rice. Autumn grass is 3-5 years before the harvest of rice ryegrass grass seed planted in the field, acre seed 2.5-3.0kg seed, when the rice harvest after the application of high content of compound fertilizer 20-30kg/mu, prompting early ryegrass grass The delivery is fast and long, and the growth period of the growth period is from November to June. It can be cut 4-6 times and produce 6000-8000 kg of fresh grass per mu. In winter and spring, the geese (fish) purchased the first batch of goose seedlings (Yauchang Goose) at the end of November to block and raise the animals. Four batches of geese were staged in batches. Each batch lasted 60 days, and the previous and subsequent batches were separated by 30 days. Raising, that is, the first batch of raising to the second batch of goose seedlings after raising to 30 days, waiting for the first batch of geese to be slaughtered, entering the third batch of goose seedlings, and the second batch of geese being slaughtered before entering the fourth batch of goose seedlings, the entire geese cycle. It lasted 120 days. At the same time, the temperature in spring rose, and the ryegrass grew vigorously. When the goose had feedstuffs, it could be cut and used as a fish feed. According to practice, it can solve 500 green fish for 3 months. Summer rice is divided into shallow fields by direct cultivating or ploughing and greening after paddy field. Winter farming adopts the method of transforming the farming geese (fish) into the grass, which solves the problem of the low benefit of planting wheat, creates a precedent for industrial structure adjustment, and promotes the healthy development of the rural economy. Second, fertility and improvement of habitat in the past winter sorghum grow grass geese can continuously improve soil fertility, improve physical properties, and promote a virtuous cycle. Practice has proved that each rye grass can raise 35-40 geese, while increasing the quality of organic fertilizer 300-500kg, received the effect of side edge support. According to the determination of soil samples collected after rice harvest in previous years, the basic soil fertility before the end of the grass was: organic matter 15.3/kg, total nitrogen 0.97mg/kg, alkaline nitrogen 109.4mg/kg, available phosphorus 3.5mg/kg, Available potassium 54mg/kg, capacity 1.31g/cm3, total pore 40.3%; the first year after planting grass geese, the soil physicochemical properties are organic matter 17.6g/kg, total nitrogen 1.08g/kg, alkaline nitrogen 138.3mg/kg Available phosphorus 8.8mg/kg, available potassium 88mg/kg, bulk density 1.l2g/cm3, total porosity 50.6%; the second year is organic matter 19.4g/kg, total nitrogen 1.16g/kg, alkaline hydrolysis nitrogen 154. Lmg/kg, fast-acting phosphorus 11.4mg/kg, available potassium 99gm/kg, bulk density 0.93g/cm3, total porosity 54.4%; the third year is organic matter 20.2g/kg, total nitrogen 1.21g/kg, alkaline hydrolysis nitrogen 163.5mg/kg, available phosphorus 13.2mg/kg, available potassium 106mg/kg, bulk density 0.89g/cm3, total porosity 56.1%; the fourth year is 25.7g/kg of organic matter, 1.38g/kg of total nitrogen, alkaline hydrolysis of nitrogen 177.6 mg/kg, available phosphorus 17.5 mg/kg, available potassium 11 9 mg/kg, bulk density 0.85 g/cm3, and total porosity 57.9%. Implementing grass breeding geese not only eliminates the residues of winter wheat oil production and use of pesticides, but also fertilizes fertility, greatly reduces the amount of chemical fertilizers used in rice production, promotes the sustainable development of ecological agriculture and the development of green foods. use. Third, high-yield and stable production, and promotion of increasing the combination of grass-meat rice and rice, both to ensure high-yield and stable production, but also to increase income, compared with the same type of field wheat, rice rotation method, cost-effective, increase grain, increase income significantly. Festival Note: Due to the constant input of high-quality organic fertilizer, the amount of chemical fertilizers can be reduced when planting rice, especially nitrogen fertilizer. From the actual nitrogen application level of rice in previous years, the production of 600-650 kg rice requires only 10.25 kg of pure nitrogen. , Saving 10 kg of pure nitrogen compared to conventional conventional fields. If the net amount of pure nitrogen is 3.60 yuan per kilogram, it will cost 36 yuan per mu. Zenggu: The average yield per mu in the four years increased by 32.8kg, and if 100kg of rice were counted by 142 yuan, it would increase income by 46.58 yuan. Synergy: In terms of growing grass geese, 35-40 geese can be kept per acre of forage. The average gain of each geese is 11.68 yuan, and the increase of mu is 408.80-467.20 yuan; the remaining fresh grass can be cut at the same time. To feed the fish, it can increase the efficiency of 100-120 yuan per acre, together with the increase in efficiency by a net increase of 591.38-669.78 yuan per mu. To change the traditional winter planting methods and develop grass breeding and geese (fish) will not only optimize the industrial structure combination, promote a benign cycle, but also make winter agriculture be used in multiple ways, which is an effective measure for tapping potential and increasing income of agricultural production.
