Mais, la disparite des ressources pastorales entre pays saheliens et cotiers accentue les mouvements de betail a l’interieur de la CEDEAO et occasionne souvent des conflits socioeconomiques entre les pasteurs transhumants et les populations des pays d’accueil. La presente etude vise a (i) contribuer a une meilleure apprehension de la transhumance transnationale en Afrique de l’Ouest, (ii) mettre en perspective cette forme de pratique d’elevage en relation avec la libre circulation des personnes et des biens dans l’espace CEDEAO et (iii) identifier des mesures d’integration de la transhumance transnationale dans cet espace.

Les resultats revelent que les politiques coloniales francaise et anglaise, puis post-coloniales, essentiellement basees sur les transformations technico-economiques, n’ont pas totalement reussi a sedentariser l’elevage transhumant.

But the disparity in pastoral resources between sahelian and coastal countries accentuates livestock movements within the ECOWAS region and often causes socioeconomic conflicts between transhumance pastoralists and people of the receiving countries. The present study aims at (i) contributing to a better understanding of cross border transhumance in West Africa, (ii) putting an emphasis on that form of livestock production in relation with the free movement of people and goods in ECOWAS region and (iii) identifying transnational transhumance integration measures in the ECOWAS region. This study is based on a critical review of colonial and post colonial policies in terms of livestock production. This is completed by a case study in a sampling of three countries of which Burkina Faso, representing departure countries on one hand and on the other hand Ghana and Togo as receiving countries for pastoralists. The results reveal that French and English colonial, then post-colonial policies, essentially based on technico-economic development, did not completely succeed in keeping to one place the pastoral livestock breeding. Livestock movements from departure countries (Burkina Faso) toward receiving countries (Togo and Ghana) are no more in reality a seasonal transhumance, but a migrationevasion.

The tick infestation started to increase during the first shower and reached a peak towards or shortly after the end of the rainy season. Tick load declined during the cool dry season to become very low or almost nil during the hot dry season. Compared to the first year, larvae in the second year were significantly high (P ≤ 0.01).

Each genetic type was reared separately from hatching to week 52 of age and was subjected to the same health care, management and feeding. Results showed that normal commercial males (DW*N) were 48.75%, 49.55% and 41.98% heavier at 16th week than their counterparts from Centre, south and North-West/West (NO/ OU) ecotypes. Feed conversion ratios between 12 and 16 weeks of age were 3.16 for DW*N and varied from 3.92 to 4.16 for local ecotypes. Normal (DW*N) and dwarf (DW*N) local females weighed 1550g and 1260g, respectively and were heavier that the heaviest local hen (889g) from the NO/OU. Feed conversion ratios were 4.62 (DW*N and DW*DW), 4.94 (Centre), 4.31 (NO/OU) and 4.35 (South). At 18 weeks of age, normal females ‘DW*N’ (1792 g) were heavier than their dwarf ‘DW*DW’ counterparts (1453 g) while hens from NO/OU (964 g), Centre (960 g) and South (1047 g) were overall lighter.
