Karakteristik Fisik dan Kimia Silase Rumput Pakchong dengan Penambahan Leguminosa pada Taraf Berbeda

Abstract

Penelitian ini bertujuan mengevaluasi pengaruh penambahan leguminosa pada taraf berbeda terhadap karakteristik fisik dan kimiawi silase rumput Pakchong serta menentukan kombinasi perlakuan yang menghasilkan kualitas silase terbaik. Penelitian menggunakan Rancangan Acak Lengkap (RAL) dengan lima perlakuan, yaitu P0 (100% rumput Pakchong), P1 (80% rumput Pakchong + 20% lamtoro), P2 (60% rumput Pakchong + 40% lamtoro), P3 (80% rumput Pakchong + 20% kaliandra), dan P4 (60% rumput Pakchong + 40% kaliandra), masing-masing dengan lima ulangan. Parameter yang diamati, meliputi: karakteristik fisik, pH, Fliegh Score, protein kasar, serat kasar, lemak kasar, Neutral Detergent Fiber (NDF), dan Acid Detergent Fiber (ADF). Hasil penelitian menunjukkan bahwa penambahan leguminosa berpengaruh nyata (P<0.01) terhadap karakteristik fisik dan kimiawi silase rumput Pakchong. Perlakuan P3 menghasilkan mutu fisik dan fermentatif terbaik. P2 menghasilkan kandungan protein kasar tertinggi dan komposisi kimia yang seimbang. Penggunaan kaliandra dalam taraf tinggi (40%) menurunkan kualitas silase, sementara lamtoro lebih stabil digunakan dalam jumlah tinggi.

This study aimed to evaluate the effect of different levels of legume addition on the physical and chemical characteristics of Pakchong grass silage and to determine the optimal treatment combination for producing high-quality silage. A Completely Randomized Design (CRD) was employed with five treatments: P0 (100% Pakchong grass), P1 (80% Pakchong grass + 20% Leucaena leucocephala), P2 (60% Pakchong grass + 40% Leucaena leucocephala), P3 (80% Pakchong grass + 20% Calliandra calothyrsus), and P4 (60% Pakchong grass + 40% Calliandra calothyrsus), each replicated five times. The parameters observed included physical characteristics, pH, Fleigh score, crude protein, crude fiber, crude fat, neutral detergent fiber (NDF), and acid detergent fiber (ADF). The results indicated that legume supplementation influenced both the physical and chemical quality of Pakchong grass silage (P<0.01). Treatment P3 produced the most favorable physical and fermentative characteristics, while treatment P2 yielded the highest crude protein content along with a more balanced chemical profile. A high inclusion level of Calliandra calothyrsus (40%) tended to reduce silage quality, whereas Leucaena leucocephala demonstrated better stability and could be incorporated at higher proportions without compromising silage quality.
