The study aimed to evaluate the efficiency of utilizing insects-spent silkworm pupae, either fed naturally on mulberry leaves (SW-N) or an artificial diet (SW-A), as well housefly larvae (HF-L) and pupae (HF-P) reared swine manure-as alternative feeds replace soybean meal in ruminant (60% grass: 40% meal) at inclusion levels 5%, 10%, 20%, 40%. This assessed their nutritional value investigated effects nutrient digestibility, rumen fermentation profile, methane (CH4) production using vitro batch culture technique. results showed that tested insects had higher protein fat contents than meal. Fatty acid analysis revealed SW-N SW-A were rich unsaturated fatty acids (70.9% 60.6%, respectively), whereas HF-L HF-P contained 52.4% 51.4%, respectively. up no negative volatile (VFA) production, increased ammonia-nitrogen concentration decreased CH4 by 20%. Although supplementation reduced 25%, exceeding 10% inhibited fermentation. In conclusion, can effectively diets; while is not recommended. These represent a promising strategy for sustainable feed development with CH4-reduction potential.

Earthworm gut digestion plays a crucial role in reducing antibiotic resistance genes (ARGs) during vermicomposting, offering significant potential for controlling ARG dissemination livestock manure. However, the impact of residual tetracycline antibiotics on this process remains poorly understood. Herein, study systematically evaluated three concentrations (0, 10, and 100 mg/kg) dynamics microbial community evolution 35-day vermicomposting cattle The results demonstrated that earthworm intestinal effectively eliminated over 96% initial load raw Noticeably, stress significantly enhanced total abundance casts (p < 0.05), with distinct response patterns observed among different types. Mechanistic analysis revealed potentially persistence through two pathways: (1) promoting horizontal transfer via mobile genetic elements, (2) altering succession influence host–microbe relationships. These discoveries contribute to our comprehension interference vermi-remediation processes provide insights optimizing mitigation strategies contaminated
