Abstract
A variant of a relatively simple Australian (Bert Kelly) method for the production of 'teaser rams' was tried out. The surgical methods used in vasectomy and the new technique are given at length. The 'Kelly type' technique involves the removal of the cauda epididymis without anesthesia. Ram lambs operated on according to the variant of the' Kelly' method worked as 'teasers' at 6 months but the effectiveness of the technique in preventing the passage of spermatozoa was not checked. A difference of approximately 6 lb. in mean live weight gain in favour of the 'Kelly' animals was not statistically significant nor was there a significant difference in mean carcass weight between two groups of ten lambs, one group castrated by removal of the testicles and the other operated on according to the variant of the 'Kelly' technique
