Local beef cattle is still the major source of domestic beef consumption, yet their productivity and quality is relatively low. This study was aimed to investigate productivity and meat quality traits of local beef cattle through fattening using cereals based concentrate containing different energy level. Nine Ongole cattle with average initial liveweight of 254.67 ± 20.7 kg and age between I1-I2 permanent incisor teeth were used in the study. They were fattened for four months and alloted into three different energy rations; they were low (ER) 57.88% TDN, medium (ES) 63.72% TDN, and high (ET) 69.67% TDN. The three rations had simmilar protein contents, between 12.42-12.96%. Observed parameters included cattle performance (ration and nutrition dry mater intake, daily gain, and feed conversion), carcass traits (carcass weight and percentage, fat thickness, and loin eye area at the 12th rib), and meat quality traits (pH, water holding capacity, tenderness, cooking loss, marbling score, and meat color). The results showed that cattle fed with high energy (ET) ration had the highest body weight and marbling score, and more efficient in feed conversion than medium (ES) and low energy (ER) rations. Local beef cattle productivity and there meat quality could be improve through fattening using high energy cereals based concentrate.

A group of components called as 3-monochloropropane-1,2-diol (3-MCPD) esters has been found in some vegetable oils, particularly palm oil. Analysis of these components needs GC-MS instrument to reach a low level detection, parts per billion or ppb level. An effort to validate the 3-MCPD esters analysis by GC-MS method (Weiβhaar method) using phenyl boronic acid (PBA) as a derivatizing agent and isotopic internal standard (IS) 3-MCPD-D5 followed by the determination of 3-MCPD in commercial palm oils has been conducted. The analytical results showed the instrumental performance as follows: instrument linearity for the analysis of 3-MCPD standard solutions containing IS 2.0 μg/mL was obtained at a concentration range of 0.25-7.50 μg/mL test solution with R2 higher than 0.990, precision of 3-MCPD as well as IS retention time was less than 2.0% which was acceptable according to JECFA guidance. Instrument detection limit (LOD) and limit of quantitation (LOQ) were read from GC-MS based on the linearity experiment, i.e. 0.17 and 0.59 μg/mL solution, respectively. Method linearity by using palm oil as a matrix also showed R2 higher than 0.990. Recovery test result at 40 μg/g gave an accuracy at 83.29 ± 7.12% which is in the range of AOAC standard (80-110%) and precision at 5.38% (less than RSDHORWITZ). Analysis of 14 palm oils from local market showed 100% of the sampels were positive to contain 3-MCPD esters. 3-MCPD esters in palm oil were found at a concentration range of 8.15-58.14 µg 3-MCPD/g sample.
