The milk production ability of the Improved Boer goat in a grass/bush community. Boer goat does from the Adelaide Research Farm were run on the dry grass/bush community of the eastern Cape . An investigation was undertaken to determine the effect of birth status, stage of lactation, milking time, and year effect on milk production. In addition, the lamb suckling technique was used to record milk production 4 and 12 hourly to determine whether 12 hourly suckling is adequate to determine milk production. There was a highly significant (P 0,01) difference between milk production in the 1982 and 1983 production year. Milk production dropped by 23% in 1983 as a result of the drought. The effect of birth status was significant (P 0,01) in 1982, but this effect disappeared during the dry year. The mean milk production of does with single kids was 1,40 l/day, that of does with twins 1,86 l/day, and that of does with triplets 1,64 l/day. Stage of lactation had no significant effect on milk production up to day 49. Generally, kids suckled more during the daytime with 4 hourly recording and more in the evening with 12 hourly sucklings. The mean milk production under 12 hourly recording was 1,64 ± 0,43 l/day and that with 4 hourly suckling 1,58 ± 0,48 l/day. The correlation coefficient between the two methods on pooled data was 0,69.
