Abstract

Livestock subsector contributes substantially to the economy of East Java Province. Thisstudy was conducted to identify and mapping the leading livestock subsector in 38 districts/cities inEast Java province based on data GDRB in 2009-2013. The analytical method used is LocationQuotient (LQ), Shift-Share (SS), and Klassen typology. LQ analysis results indicate that the livestocksubsector is a bases sector (LQ>1) in 26 districts/cities and the non base (LQ<1) in 12 districts/cities.SS analysis showed that the growth of the livestock subsector is progressive (SS>0) in 7districts/cities, while in 31 districts/cities is slow (SS<0). Based on analysis Klassen typology thisresearch concluded that the livestock subsector is the leading sector (LQ>1 and SS>0) in 7districts/cities, namely Bojonegoro, Madiun, Mojokerto, Pacitan, Pasuruan, Trenggalek, and Tuban. Key Words: Livestock Subsector, Location Quotient, Shift-Share, Klassen Tipology

Abstract

The effect of applying lactic acid bacteria (LAB) at ensiling on the nutrition and microbial composition in fermentation total mixed ration (TMR) silage was studied under laboratoryconditions. The LAB inoculants consisted of Lactobacillus plantarum (P1) commercial  and two othersLactobacillus  that isolated from local corn leaf (P2 and P3) in experiments with  TMR (11% CP and68% TDN).  The inoculants were applied each at about 106 cfu g. After treatment, the TMR wereensiled in 1 lt anaerobic jars. Six jars per treatment were sampled on days 21. At the end of theexperiment, the silages were subjected to chemical and microbiological parameters, to determinethe nutritive value and contaminant microbes compare with no LAB inoculation. In TMR silages, theLAB inoculants did not affect the nutritive value (dry matter, organic matter, crude protein, extractether, and crude fiber) however its increase LAB population and depress the contaminant microbes(aerob bacteria, yeast, and clostridia). Inoculants P3 from corn leaf seem to have the most potentialin protecting TMR from undesirable microbes.   Key Words: LAB, Chemical and Microbial Composition, TMR, Silage
