Protein Protection to Increase Ruminant Feed Protein Efficiency in Vitro

This study aimed to determine the effect of protein protection to increase ruminant feed protein efficiency in vitro. The benefit of making this protected protein is that it can provide information to farmers that the provision of protein can be more efficient. The material used as protein protection is the use of tannins from jackfruit (Arthocarpus heterophilus) leaves. The experimental design used was a completely randomized design with 4 treatments and 6 replications. Treatment 1: control (tithonia); treatment 2: addition of 0.7% condensed tannins + tithonia; treatment 3: addition of 1.7% condensed tannins + tithonia; treatment 4: addition of 2.1% condensed tannins + tithonia. Parameters observed: degree of acidity (pH); dry matter digestibility (DMD); organic matter digestibility (OMD); Crude protein digestibility (CPD). The results showed that the highest degree of acidity (pH), DMD, OMD and CPD were 7.15; 70.42%, 78.84% and 66.26%. This study concluded that the treatment with the addition of 0.7% condensed tannins, gave a total CPD of 47.58% more efficient than the control and not significantly different from other treatments.
