* Milk and meat production and adaptability<br />

(especially resistance to internal parasites) are<br />

the major selection criteria. The target KDPG<br />

for the smallholder has a milk potential of 4 kg/<br />

day at peak lactation and amature weight of 40<br />

kg.<br />

Problem Statement and Approach<br />

Developing a new breed is a relatively<br />

long-term process and the time investment<br />

must, therefore, be weighed against needs,<br />

benefits, and alternatives. At the initiation of<br />

the SR-CRSP project in Kenya, four key criteria<br />

for an acceptable and sustainable Kenya Dual<br />

Purpose goat (KDPG) were identified:<br />

1. Survey results showed that a dual purpose<br />

goat was critically needed in the high potential<br />

area of Western Kenya and that, if the forage<br />

resource was developed to its potential, it would<br />

be adequate to support the nutritional requirements<br />

of such a goat.<br />

2. On-farm and on-station studies indicated that<br />

indigenous goats were too low in genetic potential<br />

for growth and milk yield to be an acceptable<br />

base for developing a suitable dual purpose<br />

goat.<br />

3. From experience and research data, it was<br />

evident that exotic dairy breeds were not viable<br />

under the nutritional and management conditions<br />

of the smallholder farmer in Western<br />

Kenya.<br />

4. Although early research demonstrated that<br />

the F,cross between the indigenous and exotic<br />

goats performed satisfactorily, a structured<br />

crossbreeding program was not feasible for<br />

recommending to smallholder farmers.<br />

These four criteria indicated that the<br />

development of a new breed was the best<br />

strategy, because a breed:<br />

* provides a lasting genetic resource;<br />

* can be effectively selected to improve performance<br />

to suit existing conditions; and<br />

* can be adapted to conditions as they change in<br />

the future.<br />

Figure 1.Formation of the Kenya Dual Purpose Goat.<br />

Therefore, the breeding program in Figure 1 was<br />

designed and implemented to focus on the<br />

genetic aspects of producing a low maintenance<br />

and high milk-producing KDPG for Western<br />

Kenya, which could be adapted to other areas of<br />

Kenya.<br />

Critical to the current phase of stabilization<br />

and selection of an acceptable and sustainable<br />

breed are the nu<strong>mb</strong>ers of four-way cross<br />

(KDPG) animals available from which a breed<br />

can be established with the required characteristics.<br />

Currently, there are approximately 329 F,<br />

and 155 KDPG does at Ol'Magogo. Projections<br />

are that there will be approximately 400-500<br />

KDPG does by 1993, if the current breeding<br />

strategy is followed. Efforts to optimize husbandry<br />

practices to minimize kid losses are<br />

being implemented to maximize nu<strong>mb</strong>ers of<br />

animals. Body weights and weight gains are<br />

measured on all kids. Reproductive perfor­<br />
