| dc.description.abstract | LUSIYANA WANTI SIHITE, 2014: The utilization of Water Hyacinth
Fermentation of Carcass and Non Carcass Local ram sheep weaning. Under
supervisied by TRI HESTI WAHYUNI and NEVY DIANA HANAFI. .
The research aimed to examine the effect of water hyacinth fermentation
with local microorganisms (Rhizopus sp, Saccharomyces sp and Lactobacillus sp)
and Trichoderma harzianum against non carcass weight and carcass weight of
local ram sheep weaning . The experiment was conducted at the Animal Biology
Laboratory Animal Husbandry Program Agricultural Faculty, North Sumatra
University in August to November 2013 using 20 local ram sheep weaning with an
average initial body weight of 7,87± 2,18 kg. The parameters studied were
carcass weight, carcass percentage, fat percentage, non carcass weight and non
carcass percentage. The design used in the study was a completely randomized
design (CRD) with 5 treatments and 4 replications. Treatment consists of P0:
concentrate + 100 % grass, P1: concentrate + 40% grass + 60% water hyacinth
fermentation MOL, P2: concentrate + 40% grass + 60% water hyacinth
fermentation of Trichoderma harzianum, P3: concentrate + 100% water hyacinth
fermentation MOL, P4: concentrate + 100% water hyacinth fermentation of
Trichoderma harzianum.
The results showed the average carcass weight (kg) P0: 3.06, P1:2.93,
P2: 3.12, P3: 3.12 and P4: 2,76 respectively. Average percentage of carcass (%)
P0: 32.56, P1: 31.22, P2: 31.37, P3: 31.16 and P4: 29,64 respectively. Average
subcutaneous fat percentage (%) P0:3.25, P1: 2.75, P2: 2.80, P3: 3.10 and
P4: 3,08 respectively. Average pelvic fat percentage (%) P0: 0.18, P1: 0.19,
P2: 0.19, P3: 0.20 and P4: 0,24 respectively . Average percentage of kidney fat
(%) P0: 0.58, P1: 0.76, P2: 0.62 , P3: 0.61 and P4 : 0,68 respectively. Average non
carcass weight (kg) P0: 4.65, P1: 4.31, P2: 4.60, P3: 4.38 and P4: 3,82
respectively. Average non carcass percentage (%) P0: 49.71, P1: 45.92, P2: 46.92,
P3: 44.49 and P4: 45,58 respectively. Statistical analysis showed utilization of
water hyacinth fermentation with local microorganisms and Trichoderma
harzianum no significant effect on carcass weight, carcass percentage,
subcutaneous fat percentage, pelvic fat percentage, kidney fat percentage, non
carcass weight and non carcass percentage . The conclusion of this study is the
utilization of water hyacinth fermentation had no significant effect to increase
carcass weight, carcass percentage, subcutaneous fat percentage, pelvic fat
percentage, carcass weight and non carcass percentage. | en_US |
