Chemical and Minerals Composition of Dried Ruminal Fluid with Spray Drying Method with Various Hydrocolloids

This study was conducted to determine the chemical and minerals composition of dried ruminal fluid with spray drying method with various hydrocolloids. Rumen contents were taken from the slaughterhouse and powdered by spray drying with different hydrocolloids including sodium alginate (RA), guar gum (RG), chitosan (RC) and maltodextrin (RM) in two ratios (0.5 and 1% (w/v)). Samples were analyzed with a completely randomized design. The results of mean percentages showed the samples contained moisture (617 ± 0.60 to 7.29 ± 0.03%), crude protein (9.96 ± 0.06 to 13.02 ± 0.04%), ether extract (1.82 ± 0.11 to 3.43 ± 0.13%), Ash (16.25 ± 0.21 to 22.67 ± 0.15%), NDF (24.18 ± 0.12 to 27.90 ± 0.10%), and carbohydrates (36.84 ± 0.05 to 44.54 ± 0.56%). The minerals were sodium (1.98 ± 0.12 to 4.02 ± 0.17%), potassium (0.46 ± 0.07 to 0.76 ± 0.10%), magnesium (0.69 ± 0.05 to 1.02 ± 0.07%), calcium (0.33 ± 0.02 to 0.70±0.05%) and phosphorous (1.22 ± 0.07 to 1.87± 0.01%). The results indicated that dried ruminal fluid with spray drying method with various hydrocolloids has nutrition values that could provide nutrients and minerals for livestock. It is recommended in the diet of animals.
