摘要

Fodder scarcity continues to constrain livestock production in India, where the widening gap between demand and availability of quality feed highlights the need for sustainable alternatives. Agroforestry systems that integrate multipurpose tree species offer a viable solution by supplying nutritious fodder throughout the year. Chukrasia tabularis A. Juss, widely cultivated for timber, has recently gained attention for its potential as a high-quality fodder source. This study evaluated the fodder quality of seven C. tabularis clones grown under uniform field conditions, with leaf samples collected from three biological replications per clone. Proximate composition, fibre fractions, derived nutritional indices, and anti-nutritional factors were analysed using standard AOAC procedures, and clonal differences were tested through ANOVA. Significant clonal variation (p < 0.05) was observed across crude protein, crude fat, crude fibre, ash, and fibre components, indicating substantial genetic influence on fodder characteristics. Among the clones, CT HYSR 12 exhibited consistently superior nutritional attributes—including higher crude protein (14.95%), crude fat (8.26%), lower crude fibre (16.60%), and markedly lower levels of phenols, tannins, saponins, and nitrates—resulting in favourable derived indices such as higher Digestable Dry Matter, Dry Matter Intake, and Relative Feed Value. These characteristics collectively indicate better digestibility, enhanced nutrient availability, and reduced anti-nutritional constraints. The results emphasise the potential of clone CT HYSR 12 as a reliable, nutrient-dense tree fodder source. Integrating such high-performing clones into agroforestry systems can strengthen year-round feed supply, improve ruminant nutrition, and contribute to climate-smart livestock production. This study provides a scientific basis for promoting C. tabularis-based fodder interventions to enhance feed resilience under changing climatic conditions.
