Effect of Leucaena leucocephala-based multi-nutrient lick blocks on the feed intake and growth performance of buffaloes

Ruminant production in the Philippines is often hindered by limited access to high-quality feed, leading to suboptimal animal growth and productivity. To address these challenges, this study evaluated the locally made multi-nutrient lick block (MNLB) containing ipil-ipil (Leucaena leucocephala), a legume known for its nutritional value. A 30-day palatability test was conducted to assess the acceptability of the developed MNLB, using 5 male buffaloes with an average weight of 245 ± 5 kg. Additionally, a 90-day- feeding trial was carried out using 15 growing buffaloes (average age: 13.5 months, weight: 243.83 ± 5 kg), randomly assigned to three treatment groups: T1 or control (non-supplemented), T2 or commercial mineral block, and T3 or MNLB, to evaluate the growth performance, nutrient utilization, and economic viability of the legume-based MNLB. Results demonstrated that the MNLB was palatable to the animals, with an average daily consumption of 192.10 g/animal/day, providing adequate nutritional value to meet the buffaloes’ daily requirements. Moreover, MNLB supplementation significantly enhanced dry matter (DM) and crude protein (CP) intake compared to control and commercial mineral block groups. The average DM intake for T3 was 9.88 kg, and the average CP intake was 1006 g, compared to T1 (9.56 kg DM intake and 983 g CP intake) and T2 (9.59 kg DM intake and 984 g CP intake). While the commercial mineral block showed positive results, the MNLB outperformed in terms of nutritional value. In terms of cost-effectiveness, the MNLB can serve as an alternative feed supplement for small- scale farmers, offering a lower- cost option compared to commercial feed supplements. The study concluded that the MNLB has potential as a practical solution to address the nutritional challenges faced by ruminant producers in resource-limited environments. By providing a nutrient-rich and safe feed supplement, the MNLB can contribute to improved animal health, productivity, and overall farm profitability.
