Amino Acid Requirements and Biological Value of Proteins for Sheep
The Journal of Nutrition, 1987An intragastric infusion model was used to determine the biological value of three protein sources for sheep. Biological value was calculated from the regression of urinary nitrogen on nitrogen intake. A casein-amino acid mixture corresponding to previously determined metabolic amino acid requirements as well as casein alone and gelatin was studied ...

ADRENOCORTICAL STEROID REQUIREMENTS FOR INITIATION OF ACTH‐DEPENDENT HYPERTENSION IN SHEEP
Clinical and Experimental Pharmacology and Physiology, 1989SUMMARY1. Previous studies demonstrated that the combined infusion of cortisol (F), aldosterone (ALDO), deoxycorticosterone (DOC), corticosterone (B), 11‐deoxycortisol (S), 17α‐hydroxyprogesterone (17αOHP) and 17α, 20α‐dihydroxy‐4‐pregnane‐3‐one (17α20αOHP), at rates equivalent to their production during adrenocorticotrophic hormone (ACTH) treatment ...

Some observations on phosphorus homoeostasis and requirements of sheep
The Journal of Agricultural Science, 1984SummaryThe results of phosphorus kinetic studies from 149 sheep used in previous studies of calcium and P metabolism have been analysed statistically, to provide information on the mechanism of control of P homoeostasis.Whereas the rate of absorption of dietary P was increased in direct relation to P intake, the efficiency of absorption was decreased ...

Structural requirements for steroid inhibition of sheep lymphocyte mitogenesis {ulIn Vitro]
Steroids, 1984The inhibitory effects of different steroids and related compounds on sheep peripheral blood lymphocytes (PBL) during exposure to the mitogen, phytohemagglutinin (PHA), have been measured by the reduction of [3H]thymidine incorporation into DNA. Dose-response curves showed that a maximum (or near maximum effect) was achieved at a steroid concentration ...

The requirement for cobalt of sheep grazed on cobalt-deficient pastures
Australian Journal of Agricultural Research, 1969Experimental proof is presented that cobalt injected intravenously or into the abomasum at the rate of 1 mg/day is without any measurable effect on the cobalt deficiency syndrome in sheep. Similarly, depot therapy with colloidal cobalt is of no benefit.

[Space required for sheep during transport].
DTW. Deutsche tierarztliche Wochenschrift, 1997Space required for different body, positions was investigated for sheep of different weight and genetic background in undisturbed housing conditions. Body temperature, as stress indicator, was measured at different intervals during transport. The loading situation caused a distinct increase; a slight increase was measured after unloading.
