Optimizing the Production of Beef Cattle Utilizing Palm Oil Leaf Sheet Ammoniation Supplemented by Sulfur Minerals, Phosphorus and Cassava Leaf Flour

Suyitman, Lili Warly, Arif Rachmat and Dear Rahmatullah Ramadhan


Objective: This study was designed to explore the effects of supplementing processed leaf-based palm leaf rations with minerals [sulfur (S) and phosphorus (P)] and cassava flour on the optimization of bioprocess in the rumen and beef cattle growth performance. Materials and Methods: Simmental beef cattle were divided into 5 treatments and 4 replicates. The treatments consisted of A = Field grass+concentrate (60%: 40%, used as the control), B = Palm frond ammoniation + concentrate (60%: 40%), C = B + mineral supplementation S (0.4%) and P (0.27%), D = B + cassava flour (5%) and E = C + cassava flour (5%). The consumption of dry matter rations, dry matter digestibility, weight gain and feed efficiency was evaluated. Results: it is observed that the treatments had significantly different effects on Simmental cattle growth performance (p<0.05). The average dry matter ration consumption ranged from 11.25-11.76 kg/head/day, average dry matter digestibility ranged from 52.28-62.01%, average weight gain ranged from 0.84-1.01 kg/head/day and average feed efficiency ranged from 7.39-8.59%. Conclusion: Ammoniated palm oil leaves supplemented with the minerals [S (0.4%) and P (0.27%)] and cassava starch flour (5%) can replace 100% of the grass in beef cattle rations and resulted in better growth performance than was observed for control rations (grass feed) in terms of weight gain.
