Reproductive and kid performance of a newly established feral goat herd being graded up for cashmere production

Extract

Interest in farming goats for cashmere production has recently arisen, both as a means of farm diversification and, through goats grazing preferences, to utilise previously under exploited resources on hill farms.

A herd of 160 feral does of Irish and Scottish origin was established at the West of Scotland College's Kirkton Unit in June 1987 to investigate the potential for cashmere production from goats on a hill sheep farm. The Irish goats are of mixed ancestry with obvious dairy crossbreds in addition to many of more feral phenotype. The Scottish feral does came as an established group but proved excitable and difficult to handle. Whenever goats were grouped together for handling or at feeding points there was considerable fighting and other agonistic behaviour. A year later the level of this has reduced.

One hundred and fifty eight does were divided into four groups and oestrus synchronised (goats sponges 45 mg progesterone supplied by Intervet). These were then artificially inseminated by laparoscope in two, two day sessions a week apart (21/10, 22/10, 29/10 and 30/10).
