Black soldier fly larvae () (BSFL) are insect larvae with significant ecological and economic value. This study aims to investigate whether swill and manure had any effects on the transcriptome and metabolome of BSFL. Through high-throughput transcriptome sequencing, we found that larvae fed with swill exhibited higher levels of gene expression, especially with the upregulation of genes related to energy metabolism, amino acid metabolism, and redox reactions.

The formation of these dairy and meat products mainly relies on the microbiota in their gastrointestinal tract, which digests and metabolizes plant feed. The yak's gastrointestinal microbiota is closely related to the health and production performance of the host, but the molecular mechanisms of diet-induced effects in intensively farmed yaks remain to be elucidated.

- The study explores how seasonal dietary changes affect the rumen microbiota of grazing yaks in high-altitude plateau areas, focusing on differences between cold and warm seasons.
- It found increased levels of acetic acid and acetic/propionic acid ratios in yaks during the cold season, indicating significant variations in fermentation parameters.
- The results emphasize the adaptability of yaks to seasonal diet shifts and suggest implications for improving yak husbandry practices.
Article Synopsis
- Dairy buffaloes are commonly fed low-quality, high-fiber diets, which leads to inefficiencies in energy and protein utilization.
- This study investigated how different types of roughage affect the nutrient digestibility, ruminal fermentation, and microbiology in dairy buffaloes using three buffaloes with rumen fistulas.
- The findings indicated that whole corn silage resulted in the highest digestibility, while sugarcane shoot silage had the lowest, and that rumen fermentation parameters varied significantly among the different roughages tested.
Article Synopsis
- - The study investigates how yaks on a plateau in northwest Yunnan, China, adapt their rumen microbial communities in response to different feeding strategies, notably intensive feeding versus natural grazing, amid low oxygen and cold conditions.
- - Utilizing 16S rRNA and ITS sequencing methods, the research reveals significant shifts in the types and amounts of rumen bacteria between grazing and fed yaks, with intensive feeding enhancing the breakdown of dietary fiber and increasing energy extraction.
- - Results indicate that while naturally grazing yaks show higher levels of certain beneficial bacteria, intensive feeding leads to a rise in non-fiber-degrading bacteria, resulting in elevated fatty acids and altered microbial diversity, suggesting a complex adaptation to dietary changes.
