- After giving birth, it is advisable to have small pens where mother and young are kept together for a few days to prevent the mother from abandoning her kid.
- The kraal should be large enough and hygienic to prevent diseases.
(ii) Feeding management
Farmers can make more money from their ﬂocks by giving extra feed at certain times.
- During the dry season to prevent loss of weight.
- Just before the breeding season to improve fertility.
- During the last six weeks of pregnancy when the fetus is growing quickly.
- During such times goats can be fed with hay, crop remains, or should be given processed feeds.
(iii) Breeding goats
In well managed ﬂocks the farmer chooses a season for breeding and the common seasons are autumn and spring.
Autumn (at the end of the rains) or spring time (at the start of the rains). With large ﬂocks, kids can be managed better if all are born at the same time of the year. A mature he-goat can serve 40-50 female goats and in ﬂocks where there is no breeding season both male and female are kept together.
