Techniques for improving green shell laying patterns
At present, the green shell laying chicken is faced with new development opportunities. It is necessary to raise green shell egg black chickens and cultivate new economic growth points. For large-scale farming population, the large-scale rural small-scale mass rearing mode should be improved. Technical improvements should highlight the following aspects: First, a reasonable layout and a higher level of feeding conditions. In rural areas, investment in green-shelled eggs and black-bone chickens is limited, and feeding conditions are relatively simple. They cannot meet the reasonable requirements for environmental conditions of green-shelled eggs and black-breeding chickens. This is one of the reasons why the level of rural green-shell chicken eggs is not high, and it should be in a condition where it can. Next, try to improve the feeding conditions to obtain better production efficiency. Minimize the situation of mixed chickens, build chicken coops outside the village, use crops to form a barrier, and reduce the occurrence and spread of epidemics. Second, intensive brooding and disease control. Now, in rural areas, green-shelled egg-breeding black-breeding chickens are being used, and due to the widespread use of vaccines and high-antibody monitoring of viral diseases in chicken farms, the incidence of viral diseases has been reduced. On the contrary, the harm caused by bacterial diseases is increasing, and special attention should be paid. Environmental health, reduce environmental pollution, rational use of drugs, do not abuse antibiotics. Third, the use of feed should be standardized and scientific. At present, farmers raise green shell layer chickens in order to save feeding costs, make full use of resources in the region, most of their own ingredients, use a feed formula for many years, or adjust themselves, resulting in feed incomplete or nutritional imbalance; for raw materials The quality cannot be controlled, and raw materials for some small or trace amounts of additives cannot be accurately grasped, resulting in waste of raw materials and lower production levels of chickens and losses. It is recommended to use full price compounded feeds or premixed feeds with reasonable quality and reasonable price. Do not add drugs freely in feeds to ensure the hygienic quality of feeds and prevent mildew from causing unnecessary losses. (Source: "Rural Science, Technology and Information", Issue No. 2004.7)
