Transportation increases stress that subtantially decreases body weight and feed comsumption even weight gain loss after arriving at the location of fattening. A research has been conducted to study the effects of organic chromium from tannery wastes on the level of transportation stress and recovery period in beef cattle fattening. Twenty Ongole crossbreed cattles were transported from the Wirasaba Feedlot at Purbalingga in Central Java to the Agro Citra Buana Semesta Feedlot in Malangbong-Garut in West Java for about 18 hours. Completely Randomized Design (CRD) was applied, wih four repetitions. The Â Â Â Â Â Â Â Â Â Â Â Â Â Cr-organic was given seven days before and after transportation. Dose of Cr-organic used was: R0 = control diet without Â Â Â Â Â Â Â Â Cr-organic, R1 = R0 + 1.5 ppm, R2 = R0 + 3.0 ppm, R3 = R0 + 4.5 ppm, R4 = R0 + 6.0 ppm. Results showed that 3.0 ppm organic chromium of the dry matter of ration tended to affect physiology and haematological conditions, as well as decreased weight loss, shortened recovery time, improved weight gain. It is concluded that organic chromium supplementation was able to lowered stress levels, shortened recovery time, and increased daily gain for one week recovery process, especially at dose of 3.0 ppm.

The research was conducted to study the production of organic chromium from the leather tanning waste and its effect on in vitro rumen fermentation activities.Â The research was divided into two phases. The first phase was production of organic chromium by alkali hydrolysis, S cereviceae bioprocess, and duckweed bioremediation that perceived solubility in neutral and acid solution. The second phase was the supplementation of organic-Cr in ration seen from in-vitro fermented rate, digestibility and microbe rumen population. Research was conducted experimentally using 4x4 factorial patterns, on the basis of Completely Randomized Design (CRD) with three replications in each experimental unit. The first factor was the type of organic-Cr and the second factor was the supplement in ration at four levels, 1, 2, 3 and 4 ppm. The results of this research indicated that organic chromium can be synthesized by alkali hydrolysis, S cereviseae bioprocess and the activity of duckweed bioremediation.Â Among the three of processes referred, the highest level of Cr was obtained from S cereviseae bioprocess that was originated from leather-tanning waste.Â The levels of organic-Cr that was resulted from alkali hydrolysis, bioprocess from Cl3Cr.6H2O, bioprocess from Cr leather-tanning waste, and from duckweed bioremediation were 354, 1011, 3833 and 310 mg/kg, respectively. Organic-Cr characteristic of each product has relatively similar in ferment ability, dry matter and organic matter digestibility and rumen ecosystem. There is an indication that dry matter and organic matter digestibility and rumen microbe population in ration that was added with organic Cr from alkali hydrolysis was higher than other supplements.
