The paper evaluates the effects of forage type and level of concentrate supplementation on forage intake, diet apparent digestibility, purine excretion and milk production. Twelve crossbred cows (Bos taurus X Bos indicus), in early lactation were allocated to the following six dietary treatments:...

Thirty-six male Ethiopian Menz sheep, given maize stover supplemented with either cottonseed cake, noug cake or sunflower cake with or without maize grain, were used in an 88-day study comprising growth and balance trials. There was no significant interactions. Sheep consumed significantly more s...

The diurnal changes in plasma concentration and urinary excretion of purine derivatives (PD) were examined in 4 steers given feed in 1 or 2 meals daily in 2, 18-day periods. In period 1, 2 steers were fed once daily (at 08.00 h) and the other 2 twice daily (at 08.00 and 16.00 h). In period 2, the...

Six cattle (3 Boran (Bos indicus) and 3 crossbred (Bos indicus X Bos taurus) were fasted for 20 days to estimate the effect of fasting on the excretion of nitrogen (N) and purine derivatives (PD) in the urine. PD excretion (y) for each genotype was related to time (t in days) by means of an expon...

This study examined the influence of dietary variation on the usefulness of urinary spot purine derivatives (PD) collected at three periods (8:00-9:30, 14:00-15:30 and 20:00-21:30 hours) as predictors of intake by cattle. Diets comprised teff (Eragrostis tef) straw, fresh and dried Napier grass a...

The effects of 1.35, 1.8, or 2.25 kg dry matter (DM) of cottonseed cake, with (1.85 kg DM) or without molasses, on straw intake, diet digestibility, live-weight change, excretion of purine derivative (PD), and milk production of Boran (Bos indicus) cows were studied. There were no significant (P ...
