Re-Estimation Of Supplemented Methionine As Total Sulfur Amino Acid Requirement For Commercial Male Meat-Type Ducks, Kriengkrai Prahkarnkaeo, Kiattawee Choowongkomon, Boonorm Chomtee, Choawit Rakangthong, Chaiyapoom Bunchasak

The Thai Journal of Veterinary Medicine

The total sulfur amino acid (TSAA) requirements of commercial meat-type ducks were investigated by feeding diets supplemented with graded levels of DL-methionine (DL-met) compared with the standard recommendation for the strain during 3 growth phases. Five hundred male White Pekin ducklings were divided into 4 treatments, each of which consisted of 5 replicates (25 each) using a completely randomized design. From the birds aged 1-9 and 10-16 days, TSAA deficit diet significantly depressed growth rate and feed intake (P<0.05). During 10-16 days of age, the growth rate of the birds fed TSAA at 110% of the commercial requirement was faster than that of the 100% group, with the increase in growth rate and feed intake paralleling the TSAA intake (P<0.01). No significant effects of the TSAA level on productive performance of the birds from age 17-47 days were found. At the age of 47 days, increasing the TSAA levels up to 120% tended to decrease abdominal fat content (P=0.08), and significantly decreased blood uric acid concentration (P<0.01). There were no significant differences in carcass components and lipid profile in the serum. The TSAA level for optimum growth rate and FCR in commercial meat-type ducks is 100-110% of the recommended level for the strain, except during 10-16 days of age when 110% is recommended.

Effects Of Monosodium Glutamate On Heart Beat And The Embryonic Development Of Zebrafish, Naowarat Suthamnatpong, Aranya Ponpornpisit

The Thai Journal of Veterinary Medicine

The effect of monosodium glutamate (MSG) on zebrafish, Danio rerio, embryo was investigated at different concentrations of ten-fold dilution of ten times lesser than the median lethal concentration (LC50). Zebrafish embryos in the MSG treated groups (40,000 ppm and 80,000 ppm) reached highest mortality rate at 100 % within 48 hpf and 96 hpf which is significantly different (p<0.05) from negative control group. According to the Probit analysis, the LC50 of MSG on zebrafish embryo at 48 hpf and 96 hpf were 15,200 ppm and 10,300 ppm, respectively. Under the observation, effects based on the toxicity endpoint composed of lethal, sublethal and malformation effects appeared within 144 hpf. Exposure to MSG at 1,500 ppm and 150 ppm significantly produced sublethal effects and malformation development to zebrafish embryo. MSG induced cardiotoxic effects in zebrafish embryo was observed at 15, 150 and 1,500 ppm. Our results demonstrate that zebra fish embryo is a good model for the detection of toxic potential of chemical substances. Also, our data suggest the need to reconsider the safety of MSG and elucidate its mechanism of adverse reaction in further studies.
