Supplementation with forage legumes improves P . purpureum intake , which in turnincreases livestock productivity ( Mpairwe et al . , ２００３) . However , in peri‐urban areas there is no land for legume production( Mugisa et al . , １９９９ ) . Possible alternative is to incorporate them into already existing farming systems . This study was toestablish the productivity of forage legumes with P . purpureum and their contribution to milk production in the peri‐urbanareas .Materials and methods Field experiment was a randomized complete block design with four treatments , comprising intercrops ofP . purpureum with Centro ( Centrosema pubescens ) , Green leaf desmodium ( Desmodium intortum ) , Siratro ( Macrop tiliumatropurpureum ) and sole P . purpureum as a control . For the feeding experiment , treatments comprised three diets ; namelyP . purpureum fodder fed ad‐lib ( P) ; P . purpureum fed ad‐lib ＋ ４kg of Siratro herbage ( PS) ; and P . purpureum fed ad‐lib＋ ４kg of Siratro herbage ＋ ２kg of maize bran ( PSM ) . Cows were hand‐milked daily at ０７ .００ hrs and at １６ .３０ hrs .Results and discussion There were no differences ( P ＞ ０ .０５ ) between fodder DM yields from sole P . purpureum and the P .purpureum / legume mixtures ( Table １) . Crude protein ( N content x ６ .２５) contents in fodder from P . purpureum / Siratro andP . purpureum /Centro mixtures were higher ( P ＜ ０ .０１) than that in sole P . purpureum fodder . Supplementation with Siratroalone ( PS) and in combination with maize bran ( PSM ) increased ( P ＜ ０ .０５) the fat‐corrected milk yields ( Table ２ ) .Table 1 E f f ect o f intercrop p ing Pennisetum purpureum w ith f orage legumes on f odder dry matter y ields and nutrientcomposition o f f odder .Cropping system Total fodderDMYβ ( ton ha‐１ )N P CaContents in fodder ( g kg‐１ DM )Pennisetum purpureum ＋ Centro １８ 6.３３ ２２  .５b ２ g.３ ３ 3.６Pennisetum purpureum ＋ Desmodium １７ 6.９１ ２１ �.５ab ２ g.１ ３ 3.８Pennisetum purpureum ＋ Siratro １８ 6.８３ ２４  .４b ２ g.０ ４ 3.０Sole Pennisetum purpureum １６ 6.７９ １６  .１a ２ g.１ ２ 3.９F‐test Prob . ns 倡倡 ns nsTable 2 Daily milk y ield and butter f at content o f crossbred lactating cows f ed ad libitum Pennisetum purpureum basal dietsup p lemented w ith Siratro and maize bran .Parameter T reatmentsP PS PSM Mean SEM F‐test ProbFCM milk output ( kg day‐１ ) ５ è.５a ７ z.３b ７ M.２b ６ 4.７ ０ 痧.３１ 倡Butter fat Content ( ％ ) ４ 汉.１ ４ 崓.３ ３ a.９ ４ 4.１ ０ 痧.３２ nsConclusion Integrating forage legumes into Pennisetum purpureum plots in the peri‐urban areas is necessary for sustenance andproductivity of peri‐urban dairy farming .ReferencesMpairwe , D .R . , Sabiiti , E .N . , Ummuna , N .N . , Tegegne , A . and Osuji , P . ２００３ .
