This answer focuses on strength of evidence and what the studies can or cannot prove. - On the other hand, evolving consumer preferences are driving an escalating demand for premium pork, characterized by a high lean yield and reduced fat deposition []. [Liu Guanzu (2026); evidence level 1] - [] observed that dietary supplementation with 0.1% betaine linearly improved both the average daily gain (ADG) and feed conversion ratio (FCR). [Liu Guanzu (2026); evidence level 1] - The existing evidence suggests that the efficacy of betaine is modulated by multiple factors, including the supplement dose, genetic background, basal dietary composition, and growth phase. [Liu Guanzu (2026); evidence level 1] - 1 2 3 Driven by the global shift toward antibiotic-use reduction and sustainable husbandry practices, the investigation into novel feed additives that enhance growth, mitigate stress, and improve meat quality has become a focal point of contemporary research []. [Liu Guanzu (2026); evidence level 1] - However, current evidence is derived primarily from cellular and animal models, providing insights into betaine-mediated metabolic regulation and cytoprotective effects rather than established clinical efficacy. [Liu Yinuo (2026); evidence level 3] Evidence levels are sorting aids, not final clinical grades. Level 1 usually indicates systematic-review style evidence, level 2 indicates randomized trials or public-health guidance, and lower levels need more cautious wording. This page is educational.
