Article Synopsis
- - This study examined how supplementing beef cattle diets with L-Leucine (L-Leu) affects growth, blood amino acid levels, and meat quality, using 24 Angus cows divided into two groups for 120 days.
- - Results showed that L-Leu supplementation led to higher daily weight gain, better feed efficiency, and increased protein in both plasma and longissimus thoracis muscle, while also modifying the levels of several amino acids.
- - The supplementation resulted in improved meat quality indicators such as marbling and reduced fat thickness, suggesting that L-Leu enhances overall beef quality by influencing metabolic processes.
Article Synopsis
- This study compared the effects of rumen-protected leucine (RP-Leu) and unprotected leucine (RU-Leu) on fermentation parameters and bacterial composition in the rumen of beef cattle.
- The results showed that RP-Leu had a higher rumen protection rate and was more stable than RU-Leu, which degraded more slowly during the incubation.
- Meanwhile, RU-Leu enhanced gas production, microbial crude protein synthesis, and branched-chain fatty acids, making it more beneficial for regulating rumen fermentation compared to RP-Leu.
The beef cattle industry in China has advanced remarkably since its reform and opening up; consequently, China has become the world's third-largest beef cattle producer. China is also one of the countries with the most substantial research input and output in the field of beef cattle feed and nutrition. The progress and innovation by China in the research field of beef cattle feed and nutrition have undoubtedly promoted the development of the domestic beef cattle industry.

The experiment was designed as a 2 × 3 factorial arrangement. A total of 252 one-day-old Arbor Acres male broiler chickens were randomly allocated to 1 of 6 treatments: basal diet + sterile saline (negative control, NC), basal diet + LPS (positive control, PC), 7% dry FWB + sterile saline (FWB-I), 7% dry FWB + LPS (FWB-II), 7% wet FWB + sterile saline (FWB-III) and 7% wet FWB + LPS (FWB-IV), with containing 6 replicate cages/treatment and 7 broiler chickens/cage, and the experimental period lasted for 42 days.
