Abstract: Under the layout “from-south-to-north strategy of livestock and poultry breeding” in China, the quantities of livestock and poultry have increased rapidly in Liaoning Province, with nearly 70 million pigs equivalent in 2019 and nearly 100 million in 2020. With the rapid transformation of from traditional pattern to large-scale animal husbandry, the sharp increase in the quantities and concentration of livestock and poultry manure has brought huge pollution risks to the ecological environment of Liaoning Province. The imbalance and disconnection between crop planting and breeding is increasingly serious. There are many factors leading to the exacerbation of disconnection between crop planting and breeding. The inconsistency of the interests between the livestock and poultry breeding and crop planting is the primary cause. The rapid development of large-scale breeding makes the problem more and more serious. The regional planning of livestock and poultry breeding is unreasonable. The existing small and medium-sized farms in Liaoning Province have a lot of historical problems. Fecal sewage of smallholders in intensive breeding areas, especially liquid fecal sewage, is a big problem. The equipments for feces and fecal sewage treatments are outdated, the technologies are antiquated, and technical procedures are cumbersome. The non-standard technology has resulted in nutrient losses and land degradation. To promote the combination of planting and breeding in the utilization of livestock and poultry manure resources in Liaoning Province, we suggest that the preferred strategies are to coordinate the interests of planting and breeding, improve the manure reclamation technology and facilities, standardize the manure resource return technology, strengthen the promotion of research achievements and government guidance. This work would provide strategic supports for the integration of livestock and breeding industry and planting industry in Liaoning Province.

Key words: intensive breeding area, disconnection between planting and breeding, feces and sewage, total disposal and utilization of livestock wastes, integration of planting and breeding.
