説明

Growth responses of chicks were studied in the following three groups of 35 chicks each: a BD group on a basal diet, a TM group on the basal diet plus TM-10 at the rate of 0.5g/kg, and a TPA group on the basal diet plus TM-10 and disodium terephthalate (TPA) at the rate of 0.5g/kg and 0.5 per cent, respectively. TM-10 contained 20.4mg/g of oxyteracycline (OTC).<br>The average percentage of growth was 312.8, 363.4, and 379.0 per cent in the BD, TM, and TPA groups, respectively, in the 4th week and 722.1, 806.0, and 862.5 per cent, respectively, in the 7th week.<br>The blood serum level of OTC was compared between the following two groups of chicks: an OTC group on the basal diet with OTC supplement and an OTC-TPA group on the basal diet with OTC and TPA (0.5 per cent) supplement.<br>When chicks were given TM-10 (0.5g/kg) by breakfast-type feeding, the serum OTC level became the highest in both groups after three hours. The average OTC level was two times higher and maintained longer in the blood stream in the OTC-TPA group than in the OTC group.<br>When TM-10 was added to the basal diet at the rate of 1.0g per kg, the average serum OTC level was higher in both groups than in the corresponding groups in the preceding experiment. The OTC level became low rapidly in the OTC group, but it remained considerably high in the blood stream of the OTC-TPA group as long as 12 hours.
