This isdue to the low crude protein content of concentrate feeds and in available forages such as fresh elephant grass , maize forages ,and rice straw . To alleviate the problem , cassava leaves silage ( CLS) was introduced as a feed supplement for lactating dairycows in the dairy farms center of Batu district , East Java province , Indonesia through participatory training and on‐farm feedingtrials . CLS is known to contain CP more than １６ ％ in DM basis (Dao Lan Nhi et al . , ２００１ ; Kavana et al . , ２００５ ) . Increasedlivestock productivity including milk yield and body weight gain due to feeding CLS was reported by Dao Lan Nhi et al .(２００１ ) , Wanapat (２００１ ) , and Kavana et al . (２００５ ) .Materials and methods An on‐farm feeding trial of CLS to lactating dairy cows was conducted under collaboration with a groupof dairy cattle farmers called as Sumber Urip" ( meaning Source of Life" ) in Tlekung Village , Junrejo sub‐district involving３５ farmers . The farmers were involved mainly in preparing CLS for training and in evaluating the impact of feeding CLS onmilk yield . CLS were made from CL including petioles and soft stems according to the procedure of Kavana et al . (２００５ ) using３ kg molasses diluted with ２ kg water as an additive for every １００ kg CL . The trial ran for seven weeks and used six lactatingcows of ４th to ５th month of lactation belonging to six farmers . The cows were managed and fed by the farmers according to thenormal management as they have practiced . The cows were fed on elephant grass at ３０ to ４０ kg / head/ day supplemented withcommercial concentrate produced by local dairy cooperatives ５ to ８ kg / head/ day . Starting during the ４th week of the trial , ６ kg/head/ day of CLS was also given in addition to the usual feeds . Average daily milk yield and its protein and fat content of eachcow before and during feeding CLS were compared . Farmer response towards feeding CLS as feed supplement was alsoobserved .Result and discussion The CLS prepared exhibited good smell and greenish color , except CLS in two fermentation bags whichwere moldy due to the damage to the bags . CP content of the CLS in this experiment was １７ .９８ ％ which was similar to thatreported by Dao Lan Nhi et al . (２００１ ) but lower than that reported by Kavana et al . (２００５ ) . Besides having higher CP contentthan the elephant grass (９ .２３ ％ CP) and concentrate feed (１４ .６９ ％ CP) used in the ration , participating farmers also noticedrations with CLS had better palatability . All cows entirely consumed the CLS additions in the ration without the need of anadaptation period . When grass and CLS were fed together , the cows preferred to consume the CLS first rather than grass .Feeding CLS to lactating dairy cows as feed supplement also increased daily milk yield from １２ .４０ ± １ .８０ to １３ .１７ ± ２ .３９ liter /cow , and slightly increased milk protein and fat content . Same effects were also reported by IITA Annual Report (２００４ ) andKavana et al . (２００５ ) . Based on these experiences , the farmers were excited to use CLS as feed supplement , especially for theirlactating dairy cows .Conclusions Feeding CLS as feed supplement had been proved by farmers to increase their cow摧s milk yield . The farmers hadbeen excited and shown good response in utilizing CLS as feed supplement for their lactating dairy cows .ReferencesDao Lan Nhi , Mai Van Sanh and Le Viet Ly . ２００１ .
