poultry farming, raising of birds domestically or commercially, primarily for meat and eggs but also for feathers. Chickens, turkeys, ducks, and geese are of primary importance, while guinea fowl and squabs (young pigeons) are chiefly of local interest. This article treats the principles and practices of poultry farming. For a discussion of the food value and processing of poultry products, see egg and poultry processing.Get more news about Poultry Farms,you can vist our website!
Commercial poultry feeding is a highly perfected science that ensures a maximum intake of energy for growth and fat production. High-quality and well-balanced protein sources produce a maximum amount of muscle, organ, skin, and feather growth. The essential minerals produce bones and eggs, with about 3 to 4 percent of the live bird being composed of minerals and 10 percent of the egg. Calcium, phosphorus, sodium, chlorine, potassium, sulfur, manganese, iron, copper, cobalt, magnesium, and zinc are all required. Vitamins A, C, D, E, and K and all of the B vitamins are also required. Antibiotics are widely used to stimulate appetite, control harmful bacteria, and prevent disease. For chickens, modern rations produce about 0.5 kg (1 pound) of broiler on about 0.9 kg (2 pounds) of feed and a dozen eggs from 2 kg (4.5 pounds) of feed.
A carefully controlled environment that avoids crowding, chilling, overheating, or frightening is almost universal in poultry farming. Cannibalism, which expresses itself as toe picking, feather picking, and tail picking, is controlled by debeaking at one day of age and by other management practices. The feeding, watering, egg gathering, and cleaning operations are highly mechanized. Birds are usually housed in wire cages with two or three animals per cage, depending on the species and breed, and three or four tiers of cages superposed to save space. Cages for egg-laying birds have been found to increase production, lower mortality, reduce cannibalism, lower feeding requirements, reduce diseases and parasites, improve culling, and reduce both space and labour requirements.
Poultry breeding is an outstanding example of the application of basic genetic principles of inbreeding and crossbreeding as well as of intensive mass selection to effect faster and cheaper gains in meat and maximum egg production for the egg-laying strains. Maximum use of heterosis, or hybrid vigour, through incrosses and crossbreeding has been made. Rapid and efficient weight gains and high-quality, plump, meaty carcasses have been achieved thereby.
Among the world’s agricultural industries, chicken breeding in the U.S. is one of the most advanced. Intensive nutritional research and application, highly improved breeding stock, intelligent management, and scientific disease control have gone into the effort to give a modern broiler (meat chicken) of uniformly high quality produced at ever-lower cost. A modern broiler chick can reach a 2.3-kg (5-pound) market weight in five weeks, compared with the four months that were required in the mid-20th century. Additionally, annual egg production per hen has increased from about 100 in 1910 to over 300 in the early 21st century.

Watching years of mildew get blasted off a piece of patio furniture provides a unique form of satisfaction—a feeling attainable only with a pressure washer. After more than 70 hours of research and two weeks using eight pressure washer models to clean cars, outdoor chairs, and more, we found that the best pressure washer for most homeowners is the Ryobi RY142300 2300 PSI Brushless Electric Pressure Washer. All the electric washers we tested cleaned well, but the Ryobi has a durable motor, a longer hose, larger wheels for easier maneuvering, a better-designed cord, and lengthier warranty coverage than the competition.Get more news about high pressure machine,you can vist our website!
We recommend an electric pressure washer for most homeowners since electric models are easier to use and maintain than gas models. (Gas washers are more powerful, but most people don’t need all of that extra force for around-the-house tasks.) The quiet-running brushless induction motor of the Ryobi RY142300 should last for years, and the machine’s heft helps make it particularly hard to tip over, even when you’re forcefully tugging on the hose. Along with its larger wheels and cable, as well as its hose management, this sturdy design makes the RY142300 the easiest to maneuver and use of the washers in our test group. The company’s three-year limited warranty is also the longest we found. The RY142300 usually costs a little more than other pressure washers, but if you plan to use it three or more times a year, it’s the best value.
If the Ryobi RY142300 is not available, we also like the DeWalt DWPW2400 2400 PSI Electric Cold-Water Pressure Washer. In many ways, it’s identical to the Ryobi, similar in its body design, brushless motor, and overall power and usability. The DeWalt also has some advantages over the Ryobi: It comes with two additional nozzles for a wider array of spray options, a detergent tank that is easier to monitor and empty, and wide pneumatic tires, great for moving the pressure washer across bumpy lawns. The major downsides are that the cord wrap is awkward to get to and difficult to use, and the holder for the spray wand is almost entirely ineffective. The DeWalt is typically a little more expensive, too, and since we think the Ryobi’s wheels will be fine for most situations, as will its nozzle selections, we recommend that model first, but we also think anyone getting the DeWalt will be satisfied with its cleaning power.
If you have a smaller budget or plan to use your pressure washer only once or twice a year, we like the Sun Joe SPX3000 Electric Pressure Washer. For about $100 less than the Ryobi RY142300, it cleans about the same, but like most under-$200 models it has a shorter hose, a lower-quality motor, smaller wheels, a shorter warranty, and a design that’s easier to tip over. Compared with the other budget models we tried, it has a wider selection of spray nozzles; it also offers a durable metal spray wand, plus convenient hose and cord storage similar to that of the RY142300.
If you’re short on storage and you don’t mind carrying a pressure washer around, we also like the Ryobi RY1419MTVNM 1900 PSI Electric Pressure Washer. It’s much smaller than the other models we tested and has less oomph, but it can still handle most jobs (they might just take a little longer). Weighing a little over 20 pounds and sporting a top handle, it’s compact enough for you to carry it as you would a duffel bag. It has wheels and an extending handle, like a piece of luggage, but the wheels are small and have trouble managing an uneven lawn (we ended up just carrying it everywhere). This pressure washer has the same long hose as our main pick, too, but it lacks that model’s high-end induction motor and some of the other, finer details.
If you need more power or want to go beyond the reach of an extension cord and you don’t mind maintaining an engine, we recommend a gas washer. The Ryobi RY803001 3000 PSI Honda Pressure Washer cleans roughly twice as quickly as our electric pick, the Ryobi RY142300, and it’s powered by a dependable Honda gas engine. It has many of the same nice features as the RY142300 does, including oversize wheels, a long hose (in this case, 35 feet), good hose storage, ready availability, and a long warranty. The downside: It’s heavier, it’s louder, and it needs fuel, maintenance, and proper storage in the off-season. But if you need to wash a garden shed at the other end of your property, say, or a filthy boat at the end of your driveway, it’ll do the job (if you have a long enough hose).
As the popularity of thermoformed, reaction injection-molded (RIM), and powder-compacted parts continues to increase, so does the demand for compression molding presses with heating and cooling capabilities. Once reserved for specialized aerospace applications, compression molding presses are now used in a variety of industries to form parts from essentially any material, including metals, alloys, fiber-reinforced plastics, powders, composites, and rubber.Get more news about compression molding machine,you can vist our website!

Sandwich panels typically consist of an upper and a lower painted metal skin and an insulating core made of rigid polyurethane foam. Before production, the skin layers are laminated with a protective film that must withstand all of the processing steps: from profiling and preheating, the application of the polyurethane core and its exothermic foaming reaction through to the cutting and stacking of the finished panels. Get more news about Bh-sandwich Panel Series,you can vist our website!
The Challenge: Extreme Heat Resistance The foaming and curing of the polyurethane mixture poses a particular challenge as the energy released generates extreme heat in the panels. Even thinner panels can reach temperatures of up to 100°C whilst panels typically made for refrigerated storage conditions having an insulated core of up to 20 cm thick, can reach temperatures of up to 160°C during production. Any protective film used must be able to withstand these temperatures without peeling or melting whilst ensuring that the hot, freshly cut panels can be stacked together at the end of the production line, without the protective films fusing together.
Tailor-made solution for PU foamed sandwich panels With this new temperature resistant protective film which has been perfectly engineered for sandwich panels with a rigid foam PU core up to 20 centimetres thick, POLIFILM PROTECTION provides a tailor-made solution for these process requirements: The heat-resistant film made of polypropylene has a particularly high melting point of 160°C. Despite the poor wetting properties of polypropylene in general, POLIFILM PROTECTION have succeeded in equipping the film with a special water-based acrylic adhesive which also boasts a temperature resistance of up to 180°C.
There are several advantages for producers of foamed sandwich panels when using this film: Firstly, the new protective film guarantees uninterrupted and efficient production. Even after a comparatively short cooling phase, it prevents the stacked panels from fusing together. Secondly the scrap rate is reduced as the panels are no longer damaged when they are separated. Lastly, the surface of every PU sandwich panel is optimally protected from the start of production to the end of the construction work ensuring customer satisfaction.
“With our special film, manufacturers of PU sandwich panels ensure the quality of their products and improve their processing speed and reliability - production becomes noticeably more efficient. No other protective film on the market currently offers this added value,” explains Fulvio Camerini, Technical Director of the Italian production & development site of POLIFILM PROTECTION.
Amorphous metal is an alloy with a non crystalline structure produced by ultra-rapid quenching (about 1 million ℃ per second) of molten alloy. Because amorphous metal has no anisotropic properties, which originated from a crystalline structure, and there are no crystalline grain boundaries to prevent motion of magnetic domain walls, it shows excellent magnetic properties such as high permeability and low loss while having a high-saturation magnetic flux density. Amorphous metal materials for transformers, whose main ingredient is Fe (iron), are used in power line transformers and industrial transformers. Compared to conventional materials such as silicon steel, amorphous metal materials have a small no-load loss (iron loss), 1/5 that of silicon steel. Therefore, they make a major contribution to energy conservation. Hitachi Metals provides amorphous metal ribbon.Get more news about Amorphous core,you can vist our website!
Amorphous magnetic cores allow smaller, lighter and more energy efficient designs in many high frequency applications for Invertors, UPS, ASD(Adjustable speed drives), and Power supplies (SMPS). Amorphous metals are produced in using a rapid solidification technology where molten metal is cast into thin solid ribbons by cooling at a rate of one million�C/second. Amorphous magnetic metal has high permeability due to no crystalline magnetic anisotropy.
Amorphous magnetic cores have superior magnetic characteristics, such as lower core loss, when compared with conventional crystalline magnetic materials. These cores can offer superior design alternative when uses as the core material in the following components: Where typical ferrite cores can only operate up to a flux saturation level (Bsat) of 0.49 Tesla, amorphous metal cores can be operated at 1.56 Tesla. Combined with operating at permeability similar to high-end ferrites and the flexibility of manufacturing large cores sizes these cores can be an ideal solution for many of these components.
