[Effect of a nutrition factor on neonatal pathology: results of a retrospective survey on the mangrove supply to dromedary calves in the Republic of Djibouti].

The authors present a retrospective survey carried out in 23 camps of nomadic afars from Obock area (Djibouti) and concerning the traditional utilization of different types of forage from lagoon (mangrove) in relation with some of the diseases observed, particularly on calves. Four types of mangrove running are described: supply of mangrove twigs to calves less than one year old in camps and mangrove grazing for the adults; permanent feeding of mangrove associated with complementation; occasional supply of mangrove by cutting the twigs; permanent distribution of mangrove without complementation. The risk to observe diseases, namely loss of appetite, lameness, skin diseases and paralysis is 4.28 time higher when diet complementation is missing.
