Article Synopsis
- Dietary manipulation, specifically reducing crude protein (CP) while increasing soluble protein (SP) levels, can significantly lower the environmental nitrogen footprints of ruminants like sheep.
- In a study with 32 male Hu sheep, diets with a 10% reduction in CP and various SP levels resulted in lower plasma nitrogen waste and changes in gut microbiota linked to better energy metabolism.
- Increased levels of soluble protein (25-30% of CP) led to improved nitrogen absorption and reduced markers of reactive nitrogen production, suggesting a promising approach for optimizing ruminant diets and minimizing environmental impacts.
Domesticated herbivores are an important agricultural resource that play a critical role in global food security, particularly as they can adapt to varied environments, including marginal lands. An understanding of the molecular basis of their biology would contribute to better management and sustainable production. Thus, we conducted transcriptome sequencing of 100 to 105 tissues from two females of each of seven species of herbivore (cattle, sheep, goats, sika deer, horses, donkeys, and rabbits) including two breeds of sheep.

- Manipulating protein fractions in sheep diets can enhance their antioxidant capacity and immune response, particularly through reducing crude protein (CP) levels while adjusting soluble protein (SP) fractions.
- The study utilized four dietary treatments on thirty-two male Hu sheep, revealing no significant performance differences in slaughter metrics; however, lower protein diets affected various serum antioxidant and inflammatory markers.
- Ultimately, diets with higher SP levels led to improved meat quality by altering fatty acid composition, enhancing tenderness, and water retention properties despite reducing certain immune function indicators.
Sulfide produced from sewers is considered one of the dominant threats to public health and sewer lifespan due to its toxicity and corrosiveness. In this study, we developed an environmentally friendly strategy for gaseous sulfide control by enriching indigenous sulfur-oxidizing bacteria (SOB) from sewer sediment. Ceramics acted as bio-carriers for immobilizing SOB for practical use in a lab-scale sewer reactor.
