Penelitian  ini  bertujuan  untuk  mengetahui  pengaruh  substitusi  silase  serbuk  batang 
singkong  dengan  silase  daun  singkong  terhadap  kecernaan  protein  dan  serat  kasar 
pada domba  jantan  ekor tipis. Penelitian ini dilaksanakan pada Agustus--September 
2020  di  kandang  Jurusan  Peternakan,  Fakultas  Pertanian,  Universitas  Lampung. 
Analisis  kecernaan  protein  kasar  dan  serat  kasar  dilakukan  di  Laboratorium  Nutrisi 
dan Makanan Ternak, Jurusan Peternakan, Fakultas Pertanian, Universitas Lampung.
Meteri penelitian ini adalah 12 ekor Domba Ekor Tipis dengan bobot kisaran antara 
7--15  kg  yang  dipelihara  secara  intensif  pada  kandang  individu.  Penelitian  ini 
menggunakan metode Rancangan Acak Kelompok (RAK) dengan 4 perlakuan dan 3 
ulangan  yaitu  rumput  55%   +  batang  singkong  45  %  (R1),  rumput  55%+  batang 
singkong  30%  +  silase  daun  singkong  15%    (R2),  rumput  55%+  batang  singkong 
15%  +  silase  daun  singkong  30%  (R3),  rumput  55%   +  silase  daun  singkong  45%
(R4).  Peubah  yang  diamati  adalah  Kecernaan  protein  kasar  (KcPK)  dan  kecernaan 
serat kasar (KcSK).  Data yang diperoleh dianalisis dengan  menggunakan  analisis of 
variance  (ANOVA) pada  taraf nyata 5 % dan sangat nyata 1%. Hasil analisis  ragam 
yang  berpengaruh  nyata  5%  dan  sangat  nyata  1%  pada  salah  satu  peubah  maka 
dilanjutkan  dengan  uji  Duncan.  Hasil  penelitian  menujukan  bahwa  pemberian 
substitusi silase serbuk batang singkong dengan silase daun singkong  sangat berbeda 
nyata  (P<0,01)  terhadap  kecernaan  protein  kasar,  dengan  nilai  terbaik  pada  R3  : 
53,94?0,73  (%)  dan  R4  :  55.88?1.00  (%).  Tetapi  tidak  berbeda  nyata  (P<0,05) 
terhadap  kecernaan  serat  kasar  pada  domba  ekor  tipis  jantan  dan  belum  diperoleh
nilai terbaik.
Kata kuci : silase serbuk batang singkong, silase daun singkong, kecernaan protein, 
kecernaan serat kasar, dan domba ekor tipis.

This study aims to determine the effect of substitution of cassava stem powder silage 
with  cassava  leaf  silage  on  protein  digestibility  and  crude  fiber  in  thin-tailed  rams. 
This research was conducted in August -  September 2020 at the stable of the Animal 
Husbandry Department, Faculty of Agriculture, University of Lampung. Analysis of 
crude protein and crude fiber digestibility was carried out at the Laboratory of Animal 
Nutrition  and  Feed,  Department  of  Animal  Husbandry,  Faculty  of  Agriculture, 
University  of Lampung. The research metrics were 12 thin tailed sheep with a weight 
range of 7--15 kg which were kept intensively in individual cages. This study used a 
Randomized  Block  Design  (RBD)  method  with  4  treatments  and  3  replications, 
namely 55% grass + 45% cassava stems (R1), 55% grass + 30% cassava stems + 15% 
silage  of  cassava  leaves  (R2),  55%  grass.  +  15%  cassava  stalks  +  30%  silage  of 
cassava leaves (R3), 55% grass + 45% silage of cassava leaves (R4).  The variables 
observed were digestibility of crude protein (KcPK) and digestibility of crude fiber 
(KcSK). The data obtained were analyzed using analysis of variance (ANOVA) at a 
real  level  of  5%  and  very  real  1%.  The  results  of  the  analysis  of  variance  have  a 
significant effect of 5% and very significant 1% on one of the variables, then continue 
with the Duncan test. The results showed that the substitution of cassava stem powder 
silage with cassava leaf silage was significantly different (P <0.01) on crude protein 
digestibility, with the  best values  at R3: 53.94 ? 0.73 (%) and R4: 55.88 ? 1.00 (%). 
However,  it  was  not  significantly  different  (P  <0.05)  on  the  digestibility  of  crude 
fiber in thin-tailed rams but the best value was not yet obtained.
Key words: silage of cassava stem powder, silage of cassava leaves, digestibility of 
protein, digestibility of crude fiber, and thin tail sheep.
