Under the same egg production conditions, the less feed consumed, the lower the feed-to-egg ratio. To reduce feed consumption, pay attention to the following points:
1. Control of hen weight The larger the weight of the hen, the more feed it takes to feed. Therefore, the weight of the hen should be strictly controlled to make it conform to the standard weight, especially after the hen peak period is over. And feeding amount to prevent hens from getting too fat.
2. To reduce feed wastage A comprehensive balance of feed nutrient content, protein energy ratio should be reasonable. If the content of protein in the diet is high and the energy is low, the chicken will inevitably consume too much feed and cause the protein feed to be wasted; for example, if the diet has low energy and high protein, it will easily lead to over-fertilization of the chicken body, and the weight of the egg will reduce or even develop fatty liver syndrome. . To reduce feed wastage, it is also necessary to ensure the shape and height of the feed trough, and to prevent the feed from spilling out of the trough. Diligent feeding should be done less, and the amount of added material should not exceed 1/3 of the height of the feeder. The chicks are cut off at the right time and repaired before being placed in the cage can effectively prevent the chickens from pulling out of the tank. The chicken farm and the feed bank must be regularly rodent to prevent rats and birds from stealing feed. In addition, the use of nipple drinkers is preferable for drinking water, which can prevent chickens from wasting water into drinking water to cause waste.
3. Timely elimination of inferior chickens and low-yielding chickens. Weak chickens, sick chickens, discontinued chickens and other inferior chickens and low-producing eggs will continue to emerge in chickens, so we must eliminate them in time. Poor chickens consume both feed and eggs, affecting the feed-to-egg ratio and reducing economic benefits. A non-laying hen will inevitably consume 5-10 laying hens' profits; a low-producing chicken can consume 3-5 laying hens' profits. In the rearing period, weak chicks and sick and disabled chickens should be eliminated. During the peak period, chickens that have not been put into production should be eliminated. During the middle and late stages of production, it is necessary to pay attention to eliminating those chickens that have stopped production and have low egg production rate. Although the total number of chickens has been reduced, feed consumption has been reduced, the ratio of eggs to eggs has decreased, and the economic benefits have been correspondingly improved.
4. Limiting Feeding Limits Feeding can not only save feed but also increase its economic value. Restricted feeding is commonly used in the breeding of broiler breeders, which plays an important role in maintaining the proper weight of hens and increasing the production of eggs. Lightweight egg-type chickens are less prone to long-term growth and generally do not have to restrict breeding. Medium-sized egg-type chickens (such as brown-shelled laying hens) are properly bred at late stages to prevent hens from becoming over-fat and increase egg production. In principle, it is sufficient to feed the pre-laying eggs and limit the feeding after 6 months of laying. Restriction of feeding is generally adequate with 94% of the amount fed.
Medical protective masks refer to self-priming filter dustproof medical protective equipment that can filter particles in the air, prevent the spread of certain infectious microorganisms in the respiratory tract, and block droplets, blood, body fluids, secretions, etc.
Medical protective masks are masks made of one or more fabrics that have isolation effects on viral aerosols, virus-containing liquids, and so on. Under the respiratory airflow, it still has a barrier effect on viral aerosols, virus-containing liquids, etc., and when removed, the outer surface of the mask does not contact the human body, can filter particulates in the air, and block droplets, blood, body fluids, secretions, etc. . The use of medical masks includes adhesion testing, training, model selection, medical treatment and maintenance.
Composition and function: The Medical Protective Mask consists of a mask face and a tightening belt. The mask face is divided into three layers: inner, middle and outer. The inner layer is ordinary sanitary gauze or non-woven fabric. Propylene fiber melt-blown material layer, the outer layer is non-woven fabric or ultra-thin polypropylene melt-blown material layer. This high-efficiency medical protective mask is highly hydrophobic and breathable, and has a significant filtering effect on tiny virus-carrying aerosols or harmful fine dust, and the overall filtering effect is good.
The medical protective mask has a good fit with the wearer's face, can filter particles in the air, block pollutants such as droplets, blood, body fluids, secretions, etc., and can filter non-oily particles by more than 95% Personal protective equipment commonly used to deal with airborne diseases.
Product specifications: According to the national standard GB 19083-2003 "Technical Requirements for Medical Protective Masks", important performances of medical protective masks include filtration efficiency, adhesion, liquid barrier performance, comfort, hygiene, and biological safety tests.
Scope of application: Medical protective masks are better protective products. It is recommended to wear when there is serious environmental pollution or sudden medical infectious diseases (such as respiratory tract infectious diseases), to prevent the spread of viruses from patients or the environment to users.
Important indicators: including non-oily particle filtration efficiency and airflow resistance.
(1) Filtration efficiency: Under the condition of air flow (85 ± 2) L / min, the filtration efficiency of aerodynamic median diameter (0.24 ± 0.06) μm sodium chloride aerosol is not less than 95%.
(2) Tightness: The overall fit factor of the mask should not be less than 100.
How to use: How to wear a head mask
(1) Gently pinch the nose clip and place the mask on the face to ensure that it can cover the nose and mouth.
(2) The upper elastic band is fastened on the head to prevent air from entering.
(3) Tighten the lower elastic band around the neck.
(4) Be sure to fully open the mask to minimize the number of layers used during breathing.
How to wear earhook masks
(1) Pass the ear straps with both hands, place the nose clip on the upper part, and wear the mask on the nose and mouth
(2) The ear strap should be placed at the base of the ear and spread from head to toe, so that the folds of the mask are fully unfolded, which helps to cover the face to the greatest extent and minimize the number of layers required for breathing.
(3) Gently pinch the nose clip to prevent air from entering.
