  • The effects of dietary supplementation of feather meal digests(FM) and its digests on the growth of broiler chicks and taurine content in the broiler meat were examined. Total of 100 broiler chickens were assigned to five dietary treatments: T1; Control, T2; feather meal(FM) 5 % diet, T3; NaOH treated FM 5% diet, T4; HNO$_3$treated FM 5 % diet and T5; synthetic taurine 0.5 % supplemented diet. Taurine content of leg muscle was significantly(P<0.01) increased by treatments. The highest increase over the control was shown by 0.5 % taurine diet(170 %), followed by FM diet(123 %), NaOH treated FM diet(122 %) and HNO$_3$treated FM diet(63 %). Taurine content of breast muscle was increased by 246 % in 0.5 % taurine diet but FM diets were not significantly different from the control. Taurine content of heart muscle was not significantly affected by dietary treatments. There were big differences in the average taurine content of the parts or organ of the control birds; 778 $\mu\textrm{g}$/g leg muscle, 79 $\mu\textrm{g}$/g breast muscle and 1482 $\mu\textrm{g}$/g heart muscle. It was concluded that taurine content of leg muscle of broiler can be increased by supplementation of feather meal. Alkaline or acid treatment FM was not effective in improving taurine enrichment of the broiler meat.

  • Taurine content in Korean foods of plant origin was determined for 118 commonly used food items including cereals, potatoes, pulses, nuts, seeds, vegetables and fruits. Taurine concentration in food sample was analyzed using an automated amino acid analyzer(Biochrom 20, Pharmacia LKB) based on ion-exchange chromatography. Taurine was frequently detected in plant kingdom in much lower concentrations(1/100~1/1000) than those found in marine lifes and mammals. Glutinous rice, glutinous millent and sorghum did not contain taurine, while 0.7~3.9mg taurine/100g dry wt were detected in rice, barley and their products. Potatoes and sweet potatoes contained 0.3~1.2mg taurine/100g wet wt, and seasame seeds, perilla seeds, almonds, walnuts and gigko nuts contained 0.7~3.0mg taurine/100g wt. Taurine concentration was undetectable in most of the pulses, and in a large number of vegetables. Garlic bulbs, eggplants, green peppers, lotus roots, and cabbages have a relatively high level of taurine(around 1mg taurine/100g wet wt) among vegetables. Taurine was absent or found in very low levels(<1mg taurine/100g wet wt) in most of the commonly used fruits.

  • The present study was undertaken to investigate the protective role of taurine (2-aminoethanesulfonic acid) against cadmium (Cd) induced oxidative stress in murine erythrocytes. Cadmium chloride ($CdCl_2$) was chosen as the source of Cd. Experimental animals were treated with either $CdCl_2$ alone or taurine, followed by Cd exposure. Cd intoxication reduced hemoglobin content and the intracellular Ferric Reducing/Antioxidant Power of erythrocytes, along with the activities of antioxidant enzymes, glutathione content, and total thiols. Conversely, intracellular Cd content, lipid peroxidation, protein carbonylation, and glutathione disulphides were significantly enhanced in these cells. Treatment with taurine before Cd intoxication prevented the toxin-induced oxidative impairments in the erythrocytes of the experimental animals. Overall, the results suggest that Cd could cause oxidative damage in murine erythrocytes and that taurine may play a protective role in reducing the toxic effects of this particular metal.

  • The content of anserine, taurine, and L-histidine was measured by HPNC in the muscle of mature(670~690g) and juvenile(80~120g) rainbow trout fatmed in Chungsun, Korea. The concentration of anserine and taurine was higher in mature rainbow trout than in juvenile, but that of L-histidine was lower in mature than in juvenile. When measured with the chemiluminescence(CL) assay, anserine and taurine showed very powerful antioxidative activity above physiological concentration rainbow trout. Taurine still showed antioxidative activity below physiological concentration, while anserine showed prooxidative activity below that. L-Histidine was prooxidative dose-dependently. In TBA method, while taurine showed very week antioxidative effect, anserine appeared very powerful antioxidant and L-histidine prooxidant at physiological concentration. There was no synergism between anserine and taurine and anserine inhibited prooxidative effect of L-histidine.

  • Two experiments were conducted to investigate the effects of feather digests on the growth of broiler chicks and taurine content in the broiler meat. In Experiment 1, a total of 40 broiler chickens(Ross) were assigned to 4 dietary treatments: control(T1), regular feather meal(FM) diet(R-FM, T2), NaOH treated FM diet(NaOH-FM,T3), HNO3 treated FM diet(HNO3-FM,T4). In Experiment 2, a total of 70 broiler chickens were assigned to 7 dietary treatments: T1~T4(same as those of Exp. 1), modified HNO3 treated FM diet(M-HNO3-FM,T5), hair meal diet(HM,T6) and 0.22% cystine supplemented diet(CYS,T7). Feather meals and hair meal were supplemented at the 5% in the diet. In Experiment 1 and 2, weight gain of chicks fed R-FM and NaOH-FM tended to be higher than those of the control and HNO3-FM. In Experiment 2, weight gain of chicks fed CYS was highest followed by NaOH-FM, HM, M-HNO3-FM, HNO3-FM, control and R-FM. In Experiment 1, taurine content in breast muscle of chicks fed NaOH-FM was significantly higher(P<0.05) than that of control. In Experiment 2, taurine content in breast muscle of chicks fed NaOH-FM and CYS tended to be higher than that of other groups. Taurine content in leg muscle was significantly different among treatments as NaOH-FM and R-FM being highest followed by M-HNO3-FM, CYS, control, HNO3-FM and BM. Taurine content in the liver(Exp. 1 and 2) and heart(Exp. 2) were not significantly affected by treatments. These results indicated that 5% NaOH-FM in the diet was effective in increasing taurine content in breast and leg muscle of broiler chicks.

  • Taurine is only supplied to the infants from the breast-fed or formula milks because the enzyme activities of taurine biosynthesis are limited in early stages of infants . The objectives of present study were to quantitate the contents of tarurine in human milk and to estimate the intake of taurine by breast-fed infants during early period of lactation. Thirty -three lactating women, volunteered and delivered in R hospital in Serou. were recruited. Milk samples were collected every day at B1-B5 day(from 1 to 5 day dafter start of milk secretion), 15th and 30th day postpartum. Taurine contents were determined by HPLC equipped with RF-detector. The intake of taurine by infants was estimated by multiplization with the infant milk intake reported in our laboratory. The content of taurine was 406$\pm$174nmol/ml at B1-B5 day, and then gradually decreased to 359$\pm$125nmol/ml at 15th day and to 304$\pm$94nmol/ml at 30th day postpartum. The estimated intake of taurine was almost same as 24-25mg/day at B1-B5 day, and 15th , 30th days postpartum . This results was due to the increase of the intake of milk by infants.

  • An experiment was conducted to investigate the effects of dietary supplementation of feather meal (FM) on the performance of pigs and taurine content in pork. A total of 135 cross-bred (L${\times}$Y${\times}$D) pigs, weighing an average 46 kg, were assigned to five dietary treatments; Control, 3% FM supplemented diet (3% FM), 3% FM and 10 ppm pyridoxin supplemented diet (3% FMpyridoxin), 6% FM supplemented diet (6% FM) and 6% FM and 10 ppm pyridoxine supplemented diet (6% FM-pyridoxin). Each treatment had 3 replications of 9 pigs (4 gilts and 5 barrows) each. Pigs were fed for 11 weeks under a phase feeding program which consisted of grower (0-3 week), grow-finisher (4-8 week) and finisher (9-11 week) periods. During the whole feeding period, ADG and ADFI of pigs fed FM treatments tended to increase in general compared to the control. Feed conversion ratio (feed/gain) of the control was significantly (p<0.05) lower than FM treatments. Taurine content of the control was highest in heart muscle (1,393.8 ppm) followed by liver (647.3 ppm), tenderloin (601.2 ppm), ham (462.4 ppm) and loin (375.8 ppm). Taurine contents of heart, tenderloin, ham and loin were significantly (p<0.05) increased by FM treatments. Taurine content was highest in the 6% FM-pyridoxin treatment. Taurine content of heart, tenderloin, ham and loin on 6% FM-pyridoxin supplementation were increased by 91%, 23%, 27% and 29%, respectively, compared with the control. Sensory tests of the pork showed that there was no consistent response among the treatments. In conclusion, supplementation of FM and pyridoxin to a pig diet can increase taurine content of the pork.

  • Taurine supplementation has been shown to have a beneficial effect on femur bone mineral content in ovariectomized rats. It therefore seemed desirable to find out whether the beneficial effect of taurine on ovariectomized rats fed calcium deficient diet could also be reproduced. Forty female Sprague-Dawley rats were divided into two groups, One group was OVX and the other group received sham operation (SHAM), and received either control diet or a taurine supplemented diet for 6 weeks. All rats were fed on calcium deficient diet (AIN-93: 50% level of calcium) and deionized water. Bone mineral density (BMD) and bone mineral content (BMC) were measured in spine and femur. The serum and urine concentrations of calcium and phosphorus were determined, Bone formation was measured by serum osteocalcin and alkaline phosphatase (ALP) concentrations, Bone resorption rate was measured by deoxypyridinoline (DPD) crosslinks immunoassay and corrected for creatinine. Urinary calcium and phosphorus excretion, osteocalcin in blood and cross link value were not significantly different among the groups. Within the OVX group, the taurine supplemented group had not higher femur bone mineral content than the control group. This study established the need for a study on the taurine effect on bone with different calcium levels.
