Incressed interest is being shown in this subject in the northern areas of N.S.W. This has been stimulated by the activity of private practitioners in examining rams; and a Field Day conducted by the Glen Innes Branch of the Graziers' Association.
Following this Field Day, which had a large attendance, it was decided to conduct a similar function at Bonshaw, with the assistance of the Farmers and Settlers' Association. Prior to the date set down, every opportunity was taken to examine rams on various properties; to collect suitable subjects for demonstration purposes.
A total of 84 rams were examined on six properties, and seven animals suffering some abnormality. Four cases were diagnosed as Epididymitis, one as Atrophy, one as Varicocele and one Injury.
Although these numbers are by no means significant it is remarkable that the results follow closely the figures obtained by Miller and Moule (1954). The cases were found on four different properties. Two cases of Epididymitis were on one holding to which there had not been any introductions for two years; one ram having been bought for 150 guineas in 1956. A single case of Epididymitis was seen on each of two other properties.
It is regretted that only one owner was willing to present the abnormal ram for the purpose of demonstration at the Field Day. However, Mr. A. Gibson, a veterinarian who manages a property at Inverell, kindly provided four rams suffering from Epididymitis. From these rams semen samples had been collected and stained slides from these were available for viewing under microscopes at the Field Day. It was possible, therefore, to demonstrate the abnormalities of the testes after the destruction of the ram, and then view the semen samples under the microscope. It is felt that stock-owners are not particularly impressed with the significance of any abnormalities until semen samples can be seen; showing abnormal sperms.
At the Field Day in question three microscopes were used; one showing normal semen and the other two abnormal semen. If samples can be collected on the spot, then the demonstration is much more valuable.
