AbstractAbstract
[en] 2 experimental cows were fed acetyl urea several weeks before the trial was started. The first cow received a daily amount of 200 g and the second cow 855 g. On the first day of experiment both cows were given 5 mCi of 14C acetyl urea intraruminally. Up to 6 hrs after the beginning of the experiment acetyl urea in blood plasma was shown to contain a higher proportion of 14C activity than urea. 0.21 g urea and 0.18 g acetyl urea were contained in 1 kg of milk from cow No 1 while 1 kg of milk from cow No 2 contained 0.18 g urea and 0.12 g acetyl urea. The feeding of acetyl urea to dairy cows is not recommended on the basis of the fact that any further contamination of human nutrition with foreign substances should be possibly avoided. (author)

AbstractAbstract
[en] Nitrate labeled with 13N(13NO3-) was produced in a cyclotron by the 16O(p, α)13N reaction with protons having energies of 14.5 million electron volts. The 13NO3 was used as a tracer for direct quantitative measurements of denitrification rates in soils from flooded rice fields. The 13N technique provides a new tracer method for the measurement of denitrification rates in natural systems over short time intervals, without changing the concentration of NO3- in the system

AbstractAbstract
[en] The turnover of plasma urea was studied in goats fed rations with different protein contents by using 14C- and 15N-urea as tracers. The biological half-life time of urea determined with 15N-urea was always longer than that determined with 14C-urea, reflecting the difference in the metabolic pathway between the urea hydrolysates, ammonia and carbon dioxide. It was roughly estimated from the turnover studies that more than a half the quantity of urea synthesized might be transferred to the alimentary canal, including the rumen, where it underwent dissociation, with a decrease in the protein content of the ration, the percentage of transfer and dissociation increased. The 14C-urea discharged into the urine was less than 57% of the administered dose. It decreased to 3.9% in goats fed rations with a low protein content. The rate of urea turnover determined with 15N-urea was nearly consistent with the rate of urea discharge into the urine in goats fed higher protein rations. In goats fed lower protein rations, on the other hand, the rate of urea discharge decreased and its consistency with the rate of turnover determined with 15N-urea was upset. This was caused by assimilation of urea-nitrogen in rumen microorganisms, as was convinced by studying the incorporation of urea-15N into the fraction of rumen microorganisms. It was assumed that in goats fed lower protein rations the bulk of urea synthesized might have entered the endogenous recycling system within the body and assimilated by rumen microorganisms. (auth.)

AbstractAbstract
[en] Experiments were conducted on two lactating buffaloes and two lactating cows, to study the differences in the utilization of 14C-acetate, 14C-propionate and 3H-glucose for the synthesis of milk fat, milk casein and milk lactalbumin. The animals were maintained on identical condition of feed. Single infusion technique was used throughout the course of investigation. Samples of milk were collected at different time intervals between 0 to 48 h and the radioactivity was determined in different milk fractions after separation. (author)
