Grass and crop residues which form the basis of their dietparticularly during the dry season have very low nitrogen and fibre content . Supplementation of these roughages is a promisingway of alleviating nutrient deficiencies . Different types of supplementary feeding have been advocated to boost goat production( Leng ,２００３ ) of which supplementing with leguminous tree leaves has high merit . The present study was undertaken toevaluate the effects of supplementary feeding of C . calothy rsus and L . leucocephala leaves on milk production and compositionof WADG .Material and method The study was conducted with WADG in the dry season ( November ２００１ to April ２００２ ) . The WADGgrazed on mixed pasture comprised of Brachiaria ruz iz iensis and Pennisetum purpureum between ９ AM to ５ PM each day .Af ter about a month ,two bucks were introduced in the herd for two months and breeding allowed . The males were removedthereafter . １２ goats were subjected to supplementary feeding with C . calothy rsus and L . leucocephala leaves mixed in equalquantities by weight from three months prepartum up to three months postpartum . The mixture was left in the pens in theafternoon (４ PM ) at the rate of ８００ g per goat for eating at night . The remaining １２ goats served as unsupplemented controls .The following observations were made : ( i) consumption of the supplement calculated from the residue every morning ,( ii) milkproduction and composition were analysed every two weeks from kidding up to three months . The data were analysedstatistically ( Steel and Torrie ,１９８０ ) ,and the effects of supplementary feeding in milk production and composition wereevaluated .　 　 Figure 1 Weekly milk p roduction o fWADG .Results On average the goats consumed between ７００ to ８００ g of the foliagesupplement per head per day during the entire study period . Data on daily milkproduction of goats at different stages of postpartum are given in Figure １ . ThePeak milk production was observed in the second week of lactation in controlsbut the peak production occurred during the ３rd week in the groups receivingsupplements ( Figure １ ) . Supplemented goats significantly produced more milk( P ＜ ０ .０５) than controls during the entire period of study . The average weeklymilk production during the period of study in the supplemented goats wasalmost double that in controls (３６１ ± １１ vs . １８３ ± ４３ g ) . The supplementationhas not significantly influenced DM ,ash and lactose content of WADG milk .Protein content in supplemented WADG milk was significantly ( p ＜ ０ .０５ )higher than in the control group . The lipids content in milk of the control groupwas significantly ( P ＜ ０ .０５ ) higher than that of the supplemented group . Itappears that the supplementation with the leaves of Leucaena leucocephala andCalliandra calothy rsus has variable influence on milk composition of WADGduring the dry season .Table 1 A verage milk composition o f WADG on di f f erent f eeds regime .Groups Average milk composition (g/100g)DM Proteins Lipids Ash P LactoseControl １４ 换.６７ ± ０ .８５ ４  .０６ ± ０ .２９ ３ l.８３ ± ０ .３９ 倡 ０ .８１ ± ０ .０４ ０ ^.０９ ± ０ .００７ ６ m.１８ ± １ .１８Supple‐mented １４ 换.２１ ± ０ .９８ ４ 鼢.３５ ± ０ .３４ 倡 ２ 崓.５６ ± ０ .２７ ０  .８０ ± ０ .０５ ０ ^.０９ ± ０ .００３ ６ m.４８ ± ０ .８２倡 : Means with superscript in the same column are significantly different ( P ＜ ０ .０５)DM : Dry Matter ; P : PhosphorusConclusions Effect of supplementary feeding with Leucaena leucocephala and Calliandra calothy rsus on goat milk productionand composition in Cameroon proved to be highly beneficial .
