Promotion of wool growth and body weight development of sheep by alimentary supplementation with thiocyanate

: Adult sheep were administered 12 mg thiocyanate (SCN-)/kg body weight orally twice a year in altogether 16 respectively 41 single doses under conventional keeping during the period of stabling (winter) in two consecutive years. Fattening lambs got an analogous SCN- dosage with altogether 4 respectively 34 single doses under intensive keeping. Aided by this temporarily obtained balance of an alimentary SCN- deficiency the following effects were reached during conventional keeping: Significant increase of the wool mass in the greasy state and a tendency to better breading performance. During intensive fattening an increase of the wool mass and of the staple cross-section was proven statistically in the mean for all the test animals, but for the increase of the staple length it could be shown only by comparison of twins.
