| Summary: | This research was conducted in terms of determining the nutrient value of silage
rumen content, and influencing the substitute of corn forage basal feeding on the
productivity and quality of milk Holstein Friesian dairy cattle. There are three
main researches summarized in this dissertation. This research reviewed the
optimization of the Study of Lactic Acid Bacteria (LAB), in which the silage
fermentation process was in the rumen contents that were gained from the
slaughter house. In terms of producing 35% dried matter, it was combined with
the dried cassava. The treatment given was by increasing the molasses additive
materials. They were 0% (m0), 4% (m4), and 8% (m8) and LAB acidophilus
inoculation (ac), LAB casei (ca),LAB plantarum (pl), LAB mixture (bm), LAB
rumen (br), and without LAB inoculation (b0). The measuring done to the
variables was after the silage had passed the 21 days of ensilaging. It included the
measuring of pH, the content of lactic acid, acetic acid, butyric acid, N-NH3,
dried matter, organic matter, crude protein, crude fiber, nitrogen free extracted, a
number of bacteria, and organoleptic silage. The second research discussed the
ensilage duration effect of the dominant result of the three LAB
homofermentativeinoculation in the first research. Based on this research, there
were two factors included in this research, they were the duration factor of
ensilaging during 1 week (1
st
week), 2 weeks (2
nd
week), 3 weeks (3
rd
week), and
4 weeks (4
th
week). The second factor was inoculation of LAB plantarum, the
blending LAB (bm), and the rumen contentLAB (br). The variables measured
were pH, the content of lactic acid, acetic acid, butyric acid, N-NH3, the dry
matter (DM), the organic matter (OM), the crude protein (CP), the crude fiber
(CF), the nitrogen free extracted (NFE), the amount of lactic acid bacteria and the
silage of organoleptic. The first and second statistical analyses were done by using
ANOVA. The significant difference result was analyzed by using Duncan�s
multiple range tests. The third phase of the study was in vivo testing using 16
cows in the second and third periods of lactation. Furthermore, this phase was
divided into 4 treatment groups namely100% corn forage basal feeding and 0%
silage (R1), 67% corn forage and 33% silage (R2), 33% corn forage and 33%
silage (R3), and 0% corn forage and 100% silage (R4). Each of the feeding
treatment used 4 cows consisting of four magnitude classifications of body
weight. Each cow was treated by using corn forage basal feeding or silage and
added 1 kg concentrate for 2 liters milk produced in a day. The variables
measured included the dry matter digestibility (DMD), the organic matter
digestibility (OMD), the crude protein digestibility (CPD), the dry matter intake
(DMI), the organic matter intake (OMI), the crude protein intake (CPI), the total
digestible nutrients (TDN), the milk produced in a day, the fat milk content, the
protein milk, the milk specific gravity, the total solid (TS), the solid non fat (SNF)
and the degree of milk acidity by Soxhlet Henkel. The data collected was
analyzed by using variance analysis of latin square. If there was any difference
among the treatment, the variables would be analyzed by using Duncan�s multiple
range test. In the first research obtained the result of silage with pH around 3.79 -
4.49 from the treatment of br.m8 and b0.m0, the content of lactic acid was around
2.41% - 6.27% from the treatment of b0.m0 and pl.m8, the acetic acid was .64% -
1.68% from the treatment of pl.m8 and b0.m0, the butyric acid was .08% - .51%
from the treatment of br.m8 and b0.m0, the N-NH3 was 2.67% - 6.52% from the
treatment of pl.m8 and b0.m0, the organoleptic value was 57.18 - 86.07 from the
treatment ofb0.m0 and pl.m8, the decreasing content of the dried matter was
4.41% - 10.26% from the treatment ofpl.m8 and b0.m0,the decreasing content of
organic matter was 6.00% - 11.01%from the treatment ofpl.m8 and b0.m0, the
decreasing content of CP was 1.80% - 9.75%from the treatment ofpl.m8 and
b0.m0, the decreasing content of NFE was 3.61% - 6.79%from the treatment
ofpl.m8 and b0.m0, the increasing content of crude fiber was 1.08% - 4.69% from
the treatment ofpl.m8 and b0.m0, the development amount of LAB was around
1.2X107� 6.2X108from the treatment ofb0.m0 and pl.m8. The result of research I
showed the treatment of using the LAB plantarum inoculants, the blending
inoculants, LAB from the rumen content, and the adding of molasses additive
consecutive 8% produced the lactic acid content silage of 6.27%, 5.73%, and
5.16% and the amount of LAB were 6.2X108, 5.7X108, and 5.1X108 they were
higher than pH 3.84, 3.84 and 3.79, the content of acetic acid were .64%, 1.05%
and .86%, the content of butyric acid were .09%, .14%, and 0,08%, ammonia
were 2.67%, 2.97% and 2.98%, which were lower than the previous one. The
average of the decreasing of the DM were 4.41%, 5.25%, and 6.04%, the
decreasing of CP were 6.00%, 6.27%, and 6.45%, organic matter 1.80%, 1.95%,
and 4.17%, which were lower than the treatment of using LAB acidophilus
inoculants, LAB casei inoculants, and without LAB inoculants (b0).The second
research showed the using of inoculants of LAB plantarum, the blending LAB, the
LAB from the rumen content, and the adding of molasses additive 8% produced
silage, in which the average of lactic acid were 4.70%, 3.88% and 3.46%, and the
amount of the LAB were 3.40X108, 2.94X108, and 2.70X108. The pH degrees of
silage acidity were 4.07, 4.13, and 4.44, the acetic acid contents were .45%, .71%,
and .84%, the butyric acid contents were .05%, .07%, and .10%, the contents of
ammonia were 1.85%, 2.08%, and 2.42%, the decreasing contents of DM were
4.49%, 5.00%, and 5.04%, the decreasing contents of organic matter were 2.45%,
2.61%, and 2.79%, the increasing contents of CP were 1.69%, 2.15%, and 4.44%,
the decreasing of crude fiber contents were 3.37%, 3.46%, and 3.65%, the values
of organoleptic were 59.01, 58.75, and 58.75. Each of them was based on the
treatment of using LAB plantarum, the blending LAB, and LAB from the rumen
content. The role of ensilage duration showed the using of LAB plantarum
inoculants produced a better silage than the using of blending LAB and LAB from
the rumen content. They were showed by the reaching of pH silage, which were
4.05, 4.35, and 4.33 on the second week, while the contents of lactic acid were
5.19% / DM, 4.76% / DM, and 4.01% / DM. The ensilage duration affects to the
lactic acid fermentation, the fastest fermentation was reached on the second week
(at the 8
th
days � 14
th
), which was followed by the third week (at the 15
th
days �
21
st
), then the first week (at the 1
st
day � 7
th
) and the fourth week (at the 22
nd
days
� 28
th
), with the lactic acid contents were 4.65%, 5.38%,0,58%, and 5.43%.The
third research showed the consumptions of the rumen content silage a day as the
basal feeding for lactating dairy cattle, which were 13.54 kg of DM, 10.39 kg of
OM, 10.38 kg of TDN, 1499 g of CP for the R4 treatment (100% silage)
