Seven misunderstandings of using concentrated materials
All kinds of livestock and poultry concentrates are scientifically formulated and selected from high-quality feeds. After scientific processing, they are all kinds of full-price feeds. Their nutrients and use benefits are similar to those of similar full-price feeds. It is of great practical significance to use 5% or 6% concentrate to prepare full-price feed, which can effectively reduce production costs.
However, in recent years, it has been found that the use of concentrated materials in many areas is not effective, and there are seven reasons for this.
Did not choose a good brand
At present, there are many varieties of concentrated materials on the market, and the quality is uneven. If we choose unqualified or low-quality products, the feeding effect is definitely not good. Choosing concentrates depends not only on eligibility, but more importantly on quality. For example, a package of 25 kg of high-quality concentrate is 10 yuan higher than the general concentrate. After the full-price feed is prepared, the cost per kilogram of feed is increased by 0.02 yuan, and the cost of a broiler is 6 kilograms. The feed cost is increased by 0.12 yuan. Feeding high-quality concentrates, each broiler can increase the value by more than 0.24 yuan as long as it is 0.05 kilograms long. This proves that it is cost-effective to use high-quality concentrates.
Feel free to change the recommended formula
All types of concentrated materials have their own recommended recommended formulas. These recommended formulas are generally scientific, but there is no denying that some recommended formulations are not ideal. At present, some farmers have found that the formula can be changed at will. The main performance is: increase the amount of soybean meal on one side, and think that the feed with high protein quality is good, and the growth of livestock and poultry is fast. In fact, if some areas lack some kind of feed, they need to change the recommended formula, but also adjust according to the original formula, or ask the manufacturer to test and replace the new feed, and re-match.
Crushing particle size is too large or too small
The medium grain size of the feed not only ensures that the feed intake of the individual and the individual is consistent with the nutritional level of the intake, but also prevents the occurrence of metabolic diseases and improves the feed compensation. However, it has been found that in some areas, the source of the mash is too large, and the feed size of the broiler is more than 5 mm. The thickness of the feed should be: 1 mm or less for young chickens, 1 mm or more for medium chickens, 2 mm for large chickens (4.5 mm for pellets), and 2-2.5 mm for chickens (6 mm for pellets).
feed quality
Concentrates are only added in 5% or 6%, while 95% and 94% of the bulk ingredients are sourced. At present, the quality of feed sources on the market is very different, and some are also adulterated. If such a high-moisture, low-protein bean cake is used, the breeding effect can be imagined.
Mixed uniformity difference
At present, most of the farmers in rural areas only have a mixer without a mixer, and the uniformity is difficult to meet the standard requirements, which seriously restricts the proper function of the concentrated material. The coefficient of variation of mixing uniformity must not exceed 10%.
Feeding method is
It is impossible to have no fine powdery feed in the powder concentrate, and the habit of the chicken is to pick the pellets first and leave the powders, resulting in uneven nutrient intake. The solution to this problem: not too much feeding at a time, to feed the second material after the first feeding material is finished.
Storage time is too long
It has been found that some farmers have a labor-saving plan, and the processed feed is used up for ten days or even half a month, so that it is easy to mold. Chickens (especially chickens) eat this moldy feed and are prone to aspergillosis or aflatoxin poisoning. The feed processed by the farmer should not be more than one week, and the prepared feed should be stored in a dry place and kept in a safe place.
Cylindrical Lens is used to correct astigmatism in the eye, and, in rangefinders, to produce astigmatism, stretching a point of light into a line.They are available in either Plano-Concave Cylinder Lens or plano-convex cylinderical lens configurations. Plano-Concave Cylindrical lens has a negative focal length and are used for image reduction or to spread light. Plano-Convex Cylinder lens has a positive focal length, which makes the cylindrical lens ideal for collecting and focusing light for many imaging applications. Every sizes,materials cylindrical lens are available according to your detailed parameters.
Some styles of cylindrical lens have antireflective coatings to increase the transmission of light through the cylindrical lens.
Fused silica cylindrical lens is ideal for demanding laser machining and medical applications.
