Effect of lactic acid bacteria inoculants applications to the quality and chemical composition silage waste of carrot plant (Daucus carota)

Abstract

The aim of study was to determine the effect of lactic acid bacteria inoculants on the quality and chemical composition of waste carrot plant silage (Daucus carota). The study is expected to be useful as a guide and information about making a carrot plant silage waste effectively and efficiently. Using experimental methods, nested completely randomized design, with treatments of different types of bacteria: Lactobacillus collinoides, Lactobacillus delbrueckii and the mixture
(Lactobacillus collinoides and Lactobacillus delbrueckii 1:1), and the treatment time of incubation: 2 days, 3 days, 5 days 10 days 15 days and 21 days to factor nested types of bacteria. Each treatment was repeated 3 times. The results showed that lactic acid bacteria inoculants effect (P <0.05) on the quality and rate of change of chemical composition on carrot plant waste silage. Inoculants Lactobacillus delbrueckii bacteria was significantly the most effective way to condition an ensilase process at low temperature, low pH, low butyric acid content and high lactic acid content, compared to other types of inoculants. Silage carrots plants were added Lactobacillus collinoides , Lactobacillus 0 delbrueckii and mixtures, obtained an average temperature of 26,83, 25,05, 25,88 C, pH 3.71, 3.50, 3.34, 3,45 lactic acid content 10,10 %, 12.67% and 11,17% and butyric acid content of 0.65%, 0.30%, 0.38%. Silage that uses bacterial inoculants Lactobacillus delbrueckii was able to treat a small decrease in the level of the chemical composition of carrots for ensilage waste, other than another inoculants. The average reduction in chemical composition during silage ensilase using Lactobacillus collinoides, Lactobacillus delbrueckii and mix, dry matter content 34,61%, 37,36% and 35,64%, organic matter (% DM) 87,74, 88,44 and 88,14 crude protein (% DM) 7,72, 8,33 and 7,97. Neutyral Detergent Fiber (% DM) : 41,86, 48,10 and 45,82. Acid Detergent Fiber (% DM) : 30,05, 31,40 and 31,61 and Cellulose (% DM) 23,72, 25,64, 24,96. In addition, the inoculants Lactobacillus delbrueckii was also able to accelerate the stagnation and deterioration rate of change of chemical composition, ie, during five days, compared to other inoculants for 10 days. Recommended procurement of waste silage good carrot plant, using inocula of Lactobacillus delbrueckii.
