Effects of fermented straw feed on the growth,economic benefits and environmental benefits of Bellamya purificata
摘要
Abstract
[Objectives]The growth effect,economic benefits and environmental benefits of feeding fer-mented straw feed to Bellamya purificata in manual farming environments were studied to provide a technical basis for solving the cost of feed and the utilization of crop straw resource in farming Bellamya purificata.[Methods]Crushed crop straw including sugarcane leaf tails and corn stalks was used as the main raw materi-als,supplemented by distiller's grains,cassava residue,peanut meal,etc.,and compound fermentation bacteria were inoculated to produce special powdered fermented feed for Bellamya purificata via bag-type anaerobic fer-mentation.Cages were set up in ponds to conduct the experiment of comparing growth with and without feed-ing for 72 days.Two typical modes including reservoir and paddy field were selected for large-scale production demonstration and application to track and evaluate the yield and benefits.[Results]Feeding fermented straw feed significantly promoted the growth of Bellamya purificata(P＜0.05),with a feed conversion ratio of 1.2 and a feed cost of 2.28 yuan/kg for the feeding group.The per unit area yield of Bellamya purificata with fermented straw feed and farmed in reservoir mode and paddy field mode was 653.1 kg/667 m2 and 499.6 kg/667 m2,re-spectively.[Conclusions]Farming Bellamya purificata with fermented straw feed can significantly promote its growth,improve the per unit area yield and benefits of farming.It will provide an effective way for the high-value utilization of crop straw resource.关键词
