“…According to [23], majority (75%) of female WAD goats had their first kids at ages ranging between 14 and 20 months, which agreed with an earlier report [10] that the overall mean of age at first kidding was 18.5 ± 1.2 months. Doe prolificacy was 1.70 ± 0.04 [20] and was markedly affected by year of birth and parity [20] [25].…”

“…These include fertility, prolificacy, annual doe productivity and kid survival rate of WAD goats are shown in Table 1. Key literature sources for these information include the detailed review of goat breeds of Nigeria by [10] and scientific papers by [19]- [24], as well as the classical treatise "Goat Breeds of the World" [1].…”

“…WAD goats are highly prolific, can be bred all year round, with up to three parturitions in two years [6]. The goats are hardy, with the ability to thrive and survive under harsh environmental conditions of heat and humidity, ability to digest a broad range of diets and resistance to high-humidity pathogens and haemonchosis, tolerant of gastro-intestinal nematodes and trypanosomiasis [7]- [9] and the ability to thrive in tse-tse fly infested humid forests and guinea savannah zones [10] [11]. [12] noted that the mechanism of trypano-tolerance in goats, in general, differs from that of trypano-tolerant cattle.…”

“…Several investigators [1] [10] [13] [14] have reported cases of indiscriminate mating of WAD goats with Sahelian breeds of goats. In Nigeria, [10] noted specific cases of mating of WAD goats with the Red Sokoto breed, particularly in the transition zone between the rainforest and the derived savannah belt. In Burkina Faso, [14] reported that gene flow among Burkinabe goat populations (Djallonké or WAD goats, Mossi and Sahelian) was very high and this accounted for the low genetic differentiation among these breeds.…”

West African Dwarf (WAD) goats represent one of the predominant small ruminant breeds raised by resource-limited households in southern Nigeria as well as in the humid west and central Africa. This breed of goats is renowned for its adaptation to hot and humid environments, high fertility and prolificacy under backyard systems where they are raised almost with zero investment. On account of its contributions to household income and food security in southern Nigeria, there is the need for a detailed phenotypic and genetic characterization as well as the design of breeding strategies for its conservation through sustainable utilization. A critical challenge, however, is that there are no national breeding policies in most of the countries where WAD goats are raised. The objectives of this paper are: to review literature reports on trait-level information and estimates of genetic parameters for some economic characters of WAD goats; and to discuss a communal breeding scheme for its conservation through sustainable utilization. The presentation shows that WAD goats represent a highly diverse population, with particular reference to qualitative and performance-related traits, reflecting the role of traditional institutions in the maintenance of animal diversity in local populations. A genetic improvement programme involving dispersed open nucleus breeding scheme was discussed. The scheme involves backyard WAD goat units in villages as base population and dispersed communally managed schemes that maintain a population of bucks only, as nucleus units. Critical issues such as the definition of breeding goals by farmers, as well as communal project ownership, are emphasized. The ultimate goal of the breeding programme is to create opportunities for community-based management of WAD goat genetic resources for the benefit of backyard goat farmers in the region.

“…The genetic distance calculated according to Nei (1972) showed that the smallest genetic distance was between the Maradi and Sahel goats with a genetic distance of 0.025. Ngere et al (1984) reported that population of the Maradi spread South and East from Sokoto through the savannah belts giving rise to the Kano Brown and, further east, to the Sahel types of Borno State, meaning that Sahel goat could be a strain of Maradi. Hence, a reason for the least genetic distance observed.…”
