Title: Studies Concerning Reproduction In The Male Goat
Author: Fraser, Andrew Ferguson
Abstract: Artificial breeding in farm animals is a continually expanding industry but, except to a limited extent, the goat is one species which has not been included in this development. In Canada members of goat breeders' organisations frequently inquire of the possibility of an artificial insemination service becoming available for goats. Some artificial breeding organisations have expressed interest in offering such a service provided that suitable techniques could be demonstrated in this country. One particular aspect of artificial insemination which has become of immense value in recent years is the use of frozen semen. This method, facilitating the long term storage and transport of semen would obviously be most suitable for artificial breeding in goats in Canada and other countries where goat herds are few and widely scattered. The quantity of published information relating to the general field of reproduction in male goats is very limited especially on behaviour, and only a very small amount of work appears to have been done on semen in this animal. The reproduction behaviour of stud farm animals is a field of study which interests many workers in artificial breeding. In spite of this general interest however, there has been little published material on topics related to this subject and, among such material, studies on systematically observed behaviour are notable but few. Appearing to merit further research are such inadequately studied aspects of animal reproduction as (a) semen studies in goats, (b) the development of frozen semen techniques for goat semen, and (c) the reproductive behaviour of the male goat. Research on these is required to supply necessary basic information, before commercial development can take place and to aid further understanding of certain aspects of domestic animal behaviour. With the above objectives this thesis concerning semen and behaviour studies in the male goat was undertaken. The design of this project required taking certain factors into account. One factor which was given fullest consideration was the fairly standard routine of semen collection as it is followed on most artificial insemination centres for cattle breeding. This routine usually requires two semen collections to be taken from each bull on each collection date. Collection dates are routinely four to seven days apart. Since an important practical question to be answered was how well artificial goat breeding could be conducted along lines similar to artificial cattle breeding, it was decided to take semen collections from bucks also, at four to seven day intervals with two collections from each buck on each collection date. In addition to a semen collecting schedule another important factor to be considered was the seasonal character of goat breeding. For this reason the duration of the project was extended over one entire year to allow any seasonal differences to become apparent. This thesis was directed into two fields of study, one relating to behaviour and one to semen characteristics. The entire project is therefore considered in two parts. Part I considers the behaviour studies and Part II considers the semen studies.
