The technology of layer culture needs to be improved (10.3)

At present, under the general production conditions, the annual egg production of each layer is about 15-16kg, the ratio of feed to egg is about 2.7:1, and the dead panning rate is more than 20% Compared with the developed countries, there is great potential If we rely on advanced technology and strict management, and appropriately increase the breeding scale (5000-20000 chickens for farmers), there is still a lot of room for development Due to the improvement of people's living standards, the quality requirements of eggs will be higher and higher The contradiction is that the transportation distance between the egg production base and the main consumer city is long, and the urban residents are hard to eat fresh eggs Therefore, in the circulation link, the chicken farmers should form a close cooperation group to speed up the turnover, so as to improve the market competitiveness The mode and technology of large-scale feeding of small groups in rural areas need to be improved urgently The following aspects should be highlighted: 1 Reasonable layout and improvement of feeding conditions Due to the limited investment in rural chicken breeding and the relatively simple breeding conditions, it can not meet the reasonable requirements of chickens for the environmental conditions This is one of the reasons why the level of rural chicken breeding is not high at present We should try our best to improve the breeding conditions under the conditions that we can, so as to obtain better production efficiency Try to reduce the situation of mixed population and chicken, build chicken houses outside the village, use crops to form isolation zone, and reduce the occurrence and infection of epidemic diseases 2 Focus on brooding and strengthen epidemic control Farmers often raise chickens in a centralized way, such as chicks, grown chickens and laying hens, which can not guarantee isolation and epidemic prevention Therefore, it is suggested to raise chicks in a centralized way, separate chicks from adult chickens, and implement full in and full out At present, due to the widespread use of vaccines and the high antibody monitoring of chicken farms for viral diseases, the occurrence of viral diseases has been reduced On the contrary, the harm of bacterial diseases is more and more serious Special attention should be paid to ensure environmental health, rational use of drugs, and do not abuse antibiotics 3 Feed application should be standardized and scientific At present, in order to save the raising cost and make full use of the local food resources, most of the farmers use the same feed formula or adjust it by themselves for many years, which results in the incomplete matching price of feed or the imbalance of nutrients; in addition, the farmers can not control the quality of bulk raw materials, and can not accurately grasp some small or micro added raw materials, which results in Raw materials are wasted and the production level of chicken flocks is reduced and the loss is large It is recommended to select full price compound feed or premixed feed with qualified quality and reasonable price, do not add drugs in the feed at will, ensure the health of feed, and prevent unnecessary loss due to mildew China feed industry information network 785 (author:)
