Polisakarida Mengandung Mannan dari Bungkil Inti Sawit Sebagai Antimikroba Salmonella typhimurium pada Ayam
Abstract: Mannan containing
polysaccharides could be used as an alternative to replace antibiotics due to
their capacity to block the colonization of pathogenic bacteria in the
intestine of poultry. The aim of this study was to investigate mannan
containing polysaccharides from palm kernel meal (PKM) and its inhibitory
effect against Salmonella typhimurium. Hot water extractions were used to
isolate mannan containing polysaccharides from cell wall of PKM. In vivo
studies were conducted using broiler and layer chicks that were challenged
orally with 104 cfu Salmonella typhimurium on third day. Split plot design was
used as experimental design with strain as main plot and level of mannan
polysaccharides as sub plot. The levels of mannan containing polysaccharides
that were used consisted of 0 (R0); 1000 (R1); 2000 (R2); 3000 (R3); 4000 (R4)
ppm, in term of total sugar. The results indicated that compared to the control
group, feeding PKM containing mannan 4000 ppm decreased (P < 0.01)
Salmonella typhimurium incidence. The addition of mannan did not affect feed
consumption. On the contrary, the addition of 4000 ppm mannan gave
significantly higher feed/weight gain ratio of the chicks (P < 0.05). The
administration of feed supplemented with mannan from PKM did not influence
weight gain of poultry. It is concluded that mannan from PKM can prevent the colonization
of Salmonella typhimurium in poultry.
