The action research was conducted at Harapan Jaya dairy cattle group, Haurgombong village, Tanjungsari, Sumedang. The treatment was divided into four treatment R1 (grass + 100% concentrate), R2 (grass + 90% concentrate + 10% Kaliandra leaf), R3 (grass + 80% concentrate + 20% Kaliandra leaf), and R4 (grass + 70% concentrate + 30% Kaliandra leaf). The experiment used 16 heads of dairy cattle and it was divided into four blocks and replicated four times. The experimenal design used was a randomized block design and the mean of treatment was tested using orthogonal contrast.

The action described aboved gives that the stastically test and result and discussion concluded that the action research of Kaliandra (C. calothyrsus) legume in dairy cattle development area. 1. Could not increase the 4% FCM milk production of Holstein cows. The treatment produced milk yield 11,185±2,829 for R1; 13,260±2,595 for R2; 13,135±1,124 for R3; and 12,475±2,696 kg/head/day for R4. 2. The treatment did not had effect on the body weight daily gain of Holstein cows. The treatment R1 gave a decreasing in the body weight as much -0,598±0,104 while R2 -0,697±0,528; R3 -0,505±0,549; and R4 -0,581±0,424 kg/head/day. 3. The milk quality was not different based on: a. The milk fat production for treatment R1, R2, R3, and R4 was 0,459±0,104; 0,460±0,102; 0,533±0,047; and R4 0,516±0,121 kg/head/day respectively. b. The milk dry matter production of treatment R1 was 1,313±0,360, R2 was 1,520±0,305, R3 was 1,548±0,143 , and R4 was 1,493±0,309 kg/head/day. c. The production of solid non fat of treatment R2 was 0,855±0,254; and for R2, R3, and R4 was 0,958±0,210; 1,014±0,112; and R4 0,956±0,189 kg/head/day. d. The protein production of R1, R2, R3, and R4 was 0,323±0,094; 0,365±0,079; 0,385±0,041; and 0,370±0,071 kg/head/day respectively. e. The milk fat content of treatment R1 was 4,413±0,657 while R2, R3, and R4 was 4,743±0,361; 4,178±0,342; and 4,278±0,323%. f. The treatment gave the total solid content of milk for R1 as much 12,395±0,290%; R2 12,670±0,290; R3 12,063±0,211; and R4 11,923±0,487 %. g. The total solid non fat content of treatment R1 was 7,983±0,262; R2 7,950±0,092; R3 7,893±0,144; and R4 7,793±0,186%. h. The protein content of treatmen R1 was 3,025±0,099% while treatment R2, R3, dan R4 gave result 3,030±0,026; 2,975±0,071; and 2,960±0,623% respectively. i. The specific gravity of milk for treatment R1, R2, R3, and R4 was 1,025±0,000695; 1,025±0,000618; 1,025±0,000403; and 1,024±0,000929. The concentrate substitution using Calliaandra dry leaf concluded that the dairy farmer income increases for 10% substititon treatment as much Rp 2.445,55 /head/day, for 20% substititon treatment as much Rp 4.184,19 /head/day, and for 30% substititon treatment as much Rp 3. 408,27 /head/day

Based on the research action it is suggested that 20% substitution of the concentrate using Kaliandra leaf for feeding the lactating cows is the best method to increase the milk production and to give economy use.
