	abstract = {Two hundred 5-year-old Coopworth ewes were allocated to 4 groups in December 1983. Two groups (1 of which had been given a booster treatment of Fecundin(r) on 21 December) were treated with progesterone impregnated intravaginal sponges and joined with vasectomised Southdown rams on 19 January 1984. Oestrous data were recorded daily and ovulation rate determined by laparoscopy at each cycle thereafter. The other 2 groups (1 of which received a booster on 5 May 1984) were also treated with progesterone impregnated intravaginal sponges and introduced to rams on 1 June 1984. Oestrous and ovulation data were recorded until mid-September. Immunisation had no effect on the percentage of ewes exhibiting oestrus whereas season had a significant effect with an increase from 18\% in January to a peak of 95\% in April. This level of oestrous activity was maintained until the end of July after which there was a rapid decline. The proportion of ewes ovulating showed a similar pattern although peak values were attained early in February. Ovulation rate showed an increase up to March, plateauing until early July, and then declining. Values for immunised ewes were significantly higher than controls and persisted for at least 6 months in the early treatment group. These data show that although immunisation does not adversely influence the pattern of oestrus and ovulation activity in ewes subjected to the ram effect, early treatment appears to prolong the ovulation rate response.},

	abstract = {At least 6 different species of animals are currently being exported from New Zealand, horses, cattle, sheep, goats, pigs and poultry. Of theses only horses, cattle and sheep are of economic significance. Although the volume and value of livestock exports has increased dramatically in percentage terms over recent years, returns from total livestock exports still amount to less than 1\% of total exports. It is anticipated that dairy cattle exports in particular could continue to increase in geometric terms. Scope also exists for increased exports of other species but they will be subject to more constraints. While livestock exports are useful in a national economic sense and are important to individuals, companies and some geographic areas, it is unlikely that they will amount to any national economic significance in the foreseeable future. It is unlikely that livestock exports will adversely affect overseas markets for New Zealand animal products. Rather, the resulting expansion in local production is likely to stimulate consumption, leading to consumer pressure to increase imports to satisfy this demand.},
