In recent years, the scale of poultry breeding in China is gradually expanding, and the demand for feed raw materials is also rising. At present, the poultry industry is facing the problem of shortage of protein feed resources, so it is urgent to find high-quality and sustainable protein feed raw materials. The edible insect black soldier fly (Hermetia illucens L., BSF) has become a potential sustainable new protein feed, which can replace traditional protein feed materials such as soybean meal and fish meal. BSF is a saprophytic insect, which mainly feeds on organic waste, and has the characteristics of rapid growth and reproduction, extensive feeding and high feed conversion rate. The larvae or pre-pupae of BSF are rich in protein, fat, minerals, and trace elements, and their content of essential amino acids is comparable to that of fish meal and soybean meal. They also contain bioactive substances such as lauric acid, antimicrobial peptides, and chitin. Based on the nutritional characteristics of BSF larvae and processed products, this paper reviewed the research progress of BSF in poultry breeding, in order to provide a reference for the wide application of BSF in poultry production.

The policy of "changing grain to forage" is an important means to optimize the structure of farming and breeding, a powerful measure to boost the agricultural economy, and the core of promoting high-quality development of the aquaculture industry. Based on the double difference model, panel data from eight provinces implementing the "changing grain to forage" policy was selected to explore the impact of the implementation of the "changing grain to forage" policy on the scale of livestock and poultry breeding. The research results show that the implementation of the "changing grain to forage" policy has a certain driving effect on the expansion of livestock and poultry breeding scale in China. The level of intelligent breeding and fixed asset investment has a significant promoting effect on the scale of livestock and poultry breeding. The price of calves and the intensity of disease occurrence have inhibitory effects on the scale of livestock and poultry farming. Further research has found that the implementation of the "changing grain to forage" policy can significantly promote the large-scale development of livestock and poultry in breeding farms. The level of intelligent breeding has a more significant positive effect on large-scale breeding farms. Compared to medium scale farms, the intensity of disease occurrence has a relatively small adverse impact on large-scale farms. [ABSTRACT FROM AUTHOR]

With the rapid development of intensive poultry breeding in China, the demand for poultry feed raw materials is increasing rapidly. However, the shortage of cereal feed and the persistently high price make it urgent for poultry feed production industry to explore cheaper energy alternative feed. Cassava has the characteristics of high yield, rich starch and fiber, high energy value, etc. It can replace corn or other energy feed in poultry breeding. The effective use of cassava products has been proved to reduce the feed cost of poultry production. However, the utilization of cassava is limited by many factors, such as low protein and anti-nutritional factors. Using correct processing and scientific formula, the addition level of cassava in poultry diet can be improved. In this paper, the nutritional characteristics, feed utilization, and application of cassava in poultry diet were reviewed, which provided a reference for the application of cassava in poultry diet.

With the intensive development of animal husbandry, the demand for feed soybean meal increases. In order to promote the development of animal husbandry and ensure the supply and quality safety of feed in China, it is necessary to reduce the proportion of soybean meal and increase the development of protein feed resources and the supply of highquality feed. Cottonseed meal has high protein content, and the vitamin content is similar to that of soybean meal. Compared with soybean meal, cottonseed meal has a wide range of sources and is more affordable. However, cottonseed meal contains gossypol, which limits its application in animal production. Therefore, the dephenolization technology of cottonseed meal, the application of cottonseed meal instead of soybean meal in animal production and matters needing attention are summarized in the paper, which provides a reference for resource utilization of cottonseed meal, reducing livestock and poultry breeding cost and improving animal product quality.

China has a huge output of vegetables and fruits, and processed vegetable and fruit residue is rich in nutrients, rich in crude protein, crude fiber, vitamins, polyphenols, polysaccharides, flavonoids and other components, but it is not easy to preserve and has poor palatability, so it can not be directly used as animal feed. Screening of high-quality yeast and other probiotics can improve the nutritional value of vegetable and fruit residue feed and reduce feed cost, which has a positive effect on fruit and vegetable processing industry and livestock and poultry breeding industry. The paper reviewed the yeast species screening, fermentation technology and application of fermented vegetable and fruit residue in animal feed, aiming to provide reference for the research and application of fermented vegetable and fruit residue in livestock and poultry breeding.
