Kualitas Fermentasi dan Kecernaan Silase Campuran Rumput Gajah (Pennisetum purpureum) dan Litter Broiler

Abstract

Penelitian ini bertujuan mengevaluasi kualitas fermentasi dan kecernaan silase campuran berbahan rumput gajah dan penambahan litter broiler dengan tingkat persentase berbeda. Penelitian ini menggunakan rancangan acak lengkap dengan empat perlakuan dan empat pengulangan. Perlakuan tersebut terdiri dari LB0 = 100 % rumput gajah + 0 % litter broiler; LB10 = 90 % rumput gajah + 10 % litter broiler; LB25 = 75 % rumput gajah + 25 % litter broiler LB50 = 50 % rumput gajah + 50 % litter broiler. Parameter yang diujikan dalam penelitian ini adalah kualitas proksimat silase, konsentrasi amonia silase, nilai pH, nilai fleigh, dan kualitas pencernaan silase secara in vitro. Data dianalisis menggunakan ANOVA dan dilanjutkan dengan uji Tukey apabila terdapat hasil yang memiliki perbedaan signifikan (P<0,05). Hasil menunjukkan bahwa penambahan litter broiler dengan tingkat persentase berbeda secara signifikan mempengaruhi kualitas fermentasi dan kecernaan silase (P<0,05). Semakin tinggi penambahan litter maka semakin menurun kualitas fermentasi dan pencernaan silase.

This study aimed to evaluate the fermentation and digestibility quality of mixed silage made from elephant grass and the addition of broiler litter with different percentage levels. This study used a complete randomized design with four treatments and four replications. The treatment consisted of LB0 = 100% elephant grass + 0% broiler litter; LB10 = 90% elephant grass + 10% broiler litter; LB25 = 75% elephant grass + 25% broiler litter; and LB50 = 50% elephant grass + 50% broiler litter. The parameters tested were the proximate quality of silage, silage ammonia content, pH value, fleigh value, and in vitro digestion quality of silage using the Tilley and Terry method. The data obtained was analyzed using Analysis of Variance (ANOVA) and continued with the Tukey test if there were results that had significant differences (P<0.05). The results showed that the addition of broiler litter with different percentage levels significantly affected the quality of fermentation and digestibility of silage (P<0.05). The higher addition of litter, the lower the quality of fermentation and digestion of silage.
