First, heavy protein, light energy
In rural farmers and small farms, laying hens have the focus on protein, light energy, and neglect the utilization of feed protein. In daily feed formulations, energy and protein are the two major nutritional factors of feed, and they are all important and indispensable. The energy and protein in the diet or diet should be kept at an appropriate ratio. Proper selection of proportions can affect the efficiency of nutrient use and lead to nutritional disorders. When the protein in the feed is high, a large amount of uric acid is produced at the same time as the protein is decomposed into energy, causing gout in the chicken, and also increasing the feed cost. According to the nutritional needs of different growth stages of laying hens, choose the appropriate energy and protein ratio, let energy and protein do their best, and give greater play to the production performance of laying hens.
Second, the egg chicks use the meat chicken material
Some farmers use broiler chicken feed to feed 0-14 day old egg chicks, which is unscientific. The broiler chicken material has high protein and high energy. It is designed for fast-growing broiler breeds. If it is used in the egg-chicken stage, it will make the cardiovascular development system unsuitable, and it is not conducive to the body development of the laying hens, and nutrient metabolism will occur. disease. Some farmers use half of the chicken and broiler materials, which also has many problems. Eggs and broiler chickens have different types of drugs. The use of half-mixed drugs will result in insufficient dosage of the drug, which will not achieve the effect of preventing disease and promoting growth. It not only has a high incidence rate, but also affects the growth and reduces the uniformity. There may also be incompatibility in the use of broiler chicken and egg broiler drugs, causing side effects.
Because the chickens are expensive, some farmers use the 3-4 weeks to switch to the feedstock in order to save the cost of the feed. Broth is 20% crude protein, 1% lysine, 0.45% methionine, and 15%-16% crude protein, 0.7% lysine and 0.35% methionine. Vitamins and trace elements are also very different from broodstock and broodstock. During the brooding period, the need for amino acids, energy, vitamins and trace elements is high. The use of bred materials will result in lack of nutrition and even stress, which will seriously affect the performance of laying hens.
Use high-grade chick opening materials for 1-10 days of age, and use chick granules for compound feed from 11 days to 6 weeks of age. Strictly follow the different stages of the use of high-quality chick opening materials and chicken compound feed, can cultivate healthy chicks, to ensure that 5 weeks old body weight standards, to ensure high egg production rate.
Third, the use of materials by estimation, there is no exact amount of control
Some laying hens are blind in the amount of feed, most of which are estimated. Excessive use of materials not only causes over-fertilization and premature delivery of the laying hens (especially in the middle chicken stage), but also causes waste of feed and increases the cost of breeding; too few, it is difficult to reach the standard egg-laying condition, or the egg is small during the laying period. The egg rate is not high and the breeding efficiency is poor. There is also a mixture of medicines used in the prevention and treatment of diseases in laying hens.
There is a calculation method for accurate materials, which can be used by farmers for reference. The daily feed amount for the 10th day is +2 for the age of the day, for example, the daily feed for the egg chicken of 7 days old is 7+2=9g; the daily feed for the 11-20th age is the number of the daily age +1. For example, the daily feed amount of egg chickens of 15 days old is 15+1=16 grams; the daily feed amount of 21-50 days old is the number of days of age, for example, the daily feed amount of egg chickens of 30 days old is 30 grams; The daily feed amount of 51-150 days old is 50+ (day number -50) ÷2. For example, the daily feed amount of chicken in 100-day-old egg is 50+(100-50)÷2=75g; 150 days The daily feed of laying hens above the age should be stable at 100 ± 12 grams.
In this way, the cumulative consumption of a hen by a hen at 150 days is about 8.84 kilograms, and the cumulative amount of material used at 550 days is about 36.5 kilograms. Of course, the amount of materials used in different varieties and seasons should be slightly different.
Fourth, neglect the breeding materials, use low-quality and cheap materials
Some farmers think that they do not produce eggs during the breeding period, and the materials are the same, and they use low-quality and cheap materials. In fact, to ensure the nutritional supply during the breeding period, we can achieve the breeding goal of the breeding period. The breeding period is an important period to ensure the high uniformity of the chicken. The uniformity of body weight is positively correlated with the amount of egg production. The higher the uniformity, the greater the egg production.
Use high-grade broodstock. Chickens are more sensitive to amino acids in the early stages of growth, and the energy is more affected in the later stages of growth. If the protein intake is insufficient, a small-sized, short-breasted reserve chicken will be produced. At 10 weeks of age, the body weight is not up to standard, and the uniformity is poor, so that high-yield laying hens cannot be cultivated, resulting in a peak period and a short duration. The high-grade parenting materials have been rationally designed in terms of protein nutrition and energy. They are considered in a comprehensive manner in connection with the previous brooding materials, the connection with the late pre-production materials, and the use of raw materials, in order to cultivate high-quality, high-uniform reserve chickens. Provides protection.
Fifth, blind use of additives
Some farmers add multivitamins and trace elements at will, which increases the cost of breeding and causes some adverse reactions. The more additives are not used, the better the amount of vitamins and trace elements are added to the layers of the chicken feed. If it is added during the breeding process, it will be added in excess, resulting in imbalance of ingredients and leg diseases. The phenomenon of soft shell eggs and the like, the production performance is degraded.
The principles adopted for these substances are many, less, and less. Under normal circumstances, there is no need to use extra vitamins and trace elements. When stress occurs, vitamins must be added before immunization. It is best to use vitamin C alone or electrolysis.
Sixth, when the market is not good, reduce the use of feed grades
Many farmers use cheap materials in order to save farming costs and when the market is not good. Through investigation, it was found that when the price of laying hens was 5.2 yuan/kg, the farmers who insisted on using high-quality feeds had an egg production rate of more than 90%, the eggs were heavy, the ratio of eggs to eggs was low, and they were basically in a state of capital preservation and low profit. When the egg ratio is high, the peak duration is short, the cost of medication is high, and the death rate is also high, which is in a state of losing money.
Do not use low-grade cheap materials and insist on using high-quality feed. The quality of the feed can not only be seen in the short-term egg weight and egg production rate, but also depends on the health status of the chicken, the ratio of the eggs to the eggs, the peak maintenance time, and the total egg production. Choosing a good brand of laying hen feed can ensure the healthy state of the chicken and achieve the maximum egg production, so that it can not lose money.
O Ring , Rubber O Ring: An O-ring, also known as a packing, or a toric joint, is a mechanical gasket in the shape of a torus; it is a loop of elastomer with a round cross-section, designed to be seated in a groove and compressed during assembly between two or more parts, creating a seal at the interface.
O ring are installed in the groove, moderate compression section for type O Sealing Ring (circle). Because of its manufacturing cost is not high, convenient installation and therefore has been widely used in the sealing industry.
O-ring mainly used for fluid (such as: water, oil, air, chemical solvents, chemicals, etc.) and sealing the gap between a static long-term use temperature of -60 ℃ to 220 ℃.. Varies on material, the use of static pressure is less than 20MPa. Sometimes for dynamic, dynamic pressure when using less than 5MPa. And semiconductor vacuum seal.
An o-ring technically is also a gasket but it's shape and the material it is made from differs from most gaskets. The biggest difference between the two is o-rings are almost exclusively used for very high pressure applications such as hydraulics where a regular cork, paper or Rubber Gasket would fail.
Gasket is also called as static seal. It is a mechanical element use to prevent the leakage of fluid between the two components which are static or doesn't have relative motion. While Oil Seal also called as dynamic seal is use to prevent leakage of fluid between two components having relative rotary or sliding motion.
A gasket is primarily used to seal two mating surfaces. It prevents leakage of fluids. Washers on the other hand are used primarily to spread pressure evenly, and are used in places of high vibration.
A washer is a thin plate (typically disk-shaped) with a hole (typically in the middle) that is normally used to distribute the load of a threaded fastener, such as a screw or nut.
