Misunderstanding of Chicken Breeding and Its Improvement
(1) Blind introduction of species selection. Some farmers have neglected the quality of chickens because of their low prices. For example, they often introduce some fragile and weak chickens from non-regular breeding farms or farmers; some simply pursue fashion and introduce some products that are not suitable for local consumption. “Yang†chicken breeds or new varieties that grow in natural conditions; some also introduce chickens of breeder chickens and laying-hen breeds; others keep “guts†and local chickens together or raise them in the same column; more do not undergo quarantine. Directly from the infected area to buy chickens, causing cross-infection of the disease. To this end, we must scientifically introduce breeding chickens. The specific requirements are: (1) The breeder's breed should be selected based on the economic purpose of raising the bird. In general, from a commoditization point of view, chickens can be divided into layer chickens, broiler chickens, and egg-and-meat breeders. For example, laying hens have white-shelled hens (such as Star-288, Jingbai, and Nick, etc.) and brown-shell hens (such as Rose, Star-597, Isa, etc.); broilers have white broilers (such as Star Broilers Avian, AA chicken, etc.) and yellow feather broilers (Haypes yellow chicken, Di Gao yellow chicken, etc.); and local breeder chickens are mostly used for both types. (2) Three principles must be observed for the introduction of breeder chicks, namely, the principle of similarity between the country of origin and the local natural conditions, the principle of primary introduction and the principle of market orientation, and the principle of market orientation (selecting varieties with large market demand). (3) To select seedlings that meet the standardization criteria, it is generally recommended to introduce the seedlings from a regular breeder farm. Only those species that have been certified by the relevant national or provincial or municipal authorities can be selected to meet the variety standards. seedling. (b) Indiscriminate use of materials in feed selection. Some farmers believe that the use of low-priced feeds can reduce the cost of raising chickens, thereby buying large amounts of low-quality feed from feed mills. As a result, the feed intake of chickens is greatly increased, but it is not worth the candle; some farmers only pay attention to the color of feeds. Odor to choose feed, think blue green (actually copper sulfate) and fish smell (actually lure agent) like, in fact, this may be the bait of the business; some only focus on the use of premixes and concentrates and Regardless of the quality and quantity of bulk feeds (eg, grain feeds), the “big head†is lost and suffers losses; other farmers are abusing feed additives and treating feed additives as panacea, which in turn increases costs. For this reason, chicken feed must be used correctly. The specific approach is: (1) Feeding chickens with compound feeds (without low-nutrient, low-quality feeds) should be avoided. Single feeds and incomplete nutrition should not be avoided. Determine the ratio of protein, energy, minerals (especially calcium and phosphorus) and vitamins and other nutrients in the feed according to the purpose of the chicken (eg laying hen or broiler) and age (chicken or adult chicken), so as to prepare a comprehensive nutrition layer Materials, broiler material and broiler material, of course, can also be purchased from the regular manufacturers of different types of full-priced materials. (2) Adjust ingredients according to seasonal changes. For example, it is appropriate to increase the proportion of green feed in the summer, and increase the amount of sugary and starchy cereal feeds in the winter. (3) It is necessary to regularly feed the material. To allow the chicken to feed the feed in the feed tank, do not feed it more than once. (4) Do not change feed suddenly. Each time the feed is changed, it is carried out in descending (former feed) and incremental (new feed) ways so that the flock has an adaptation process. (5) prohibit the abuse of additives. If you use compound feed, you do not need to add other additives. If additives are really needed, special additives should be used depending on the purpose of production (eg, for eggs or meat), and antibiotics and other pharmaceutical additives are strictly prohibited. (3) It is not scientific in management. Some farmers tend to breed chickens with healthy chickens in the same house, but do not pay attention to isolation and rearing. Some farmers use drugs for long-term or blindly feeding chickens, which not only increases the damage to the body but also causes drug resistance. Instead, it has brought difficulties to the epidemic prevention work. Moreover, due to the inappropriate use of medicines, it has not only cured the disease, but has also increased the cost. For this reason, scientific feeding and management methods must be adopted. The specific approach is: (1) We must isolate the different uses (egg or meat) and different growth and development stages (chicken, adult chicken) and sick chickens, and do not polyculture. (2) To manually supplement light. Generally, it is advisable to add 3 watts of lighting per square meter according to the use area of ​​the chicken house. The distance between the lamp and the lamp is 3 meters, and the height of the lamp is 2 meters from the ground. Supplemental lighting can be performed before dawn or after dark, supplemented by 4-5 hours per day. (3) Ensure adequate drinking water. Each egg produces approximately 340 ml of water per layer. The chicken should be clean and fresh, don't add too much one time. (4) Do not use drugs for a long time or blindly use drugs. Both antibiotics and other pharmaceutical additives should be banned during the egg laying period of laying hens and before slaughter of broilers. (5) Do not stack feed with pesticides or fertilizers to prevent feed pollution.
