1 The Production and Quality of Pasture which is Introduced with Legume for Dairy Goat Karti, P.D.M.H., L. Abdullah, D.A. Astuti,., N. Kurniaty, & Nissa Faculty of Animal Science, Bogor Agricultural University, Bogor, West Java Indonesia

2 Introduction Potential benefit of pasture which is introduce with legume are : 1. legume fix atmospheric nitrogen 2. legumes are generally of higher quality than grasses 3. legume help to stabilize the uniformity of pasture.

3 Excellent quality of forages could get the best milk production of goats. Feeding of legume forage species will increase compliance the protein need of dairy goats

4 Mineral uptake such as N, P, Ca can increase the quality of forage (Karti, 2010). There is a problem in pasture research unit consists of a single type of grass (Brachiaria humidicola)

5 The purpose of this research is to study the introduction of legume on Brachiaria humidicola pasture for diary goat

6 Material and Method The materials used were pasture of B humidicola, three kinds of legumes, i.e. Pueraria javanica, Centrosema pubescens and Calopogonium mucunoides, NPK fertilizer, manure and Soil Potential Microorganism. Their was obtained from Agrostology Laboratory, Faculty of Animal Science, Bogor Agricultural University. The experiment used block randomized design with eight (8) treatmens and four (4) replications.

8 The treatments were : P 1 : Control (Pasture of Brachiaria humidicola), P 2 : Pasture is introduced with Pueraria javanica, Centrosema pubescens and Calopogonium mucunoides and fertilized with NPK), P 3 : Pasture is introduced with P. javanica, P 4 : Pasture is introduced with C. pubescens, P 5 : Pasture is introduced with C. mucunoides, P 6 : Pasture is introduced with P. javanica and C. pubescens, P 7 : Pasture is introduced with P. javanica and C. mucunoides P 8 : Pasture is introduced with P. javanica, C. pubescens and C. mucunoides. P 3 until P 8 used NPK half doses, manure and soil potential microorganism.

9 Parameters observed were DM Production, N, P, K, Ca, Mg Uptake, Dry Matter Digestability Coefisient (DMDC), Organic Matter Digestability Coefisient (OMDC), Volatile Fatty Acids (VFA), Amonia (NH 3) The data were analyzed with analysis of variance and the differences between treatments were analyzed with analysis of Duncan Multiple Range Test (DMRT).

12 Production of dry matter, P and K uptake was significantly increased which is introduce with legume (P 2 -P 8 ) as compared with P 1. Production of dry matter in treatment with half doses of inorganic fertilizer, manure and potential microorganisms (P 3, P 5, P 6, P 7, P 8 ) were significantly higher than just using inorganic fertilizer (P 2 ).

13 Uptake of N, Ca on treatment with half doses of inorganic fertilizer, manure and potential microorganism (P 3 -P 8 ) were significantly higher than only using inorganic fertilizer (P 2 ). Uptake of Mg from P3, P7 were significantly higher than P1, P2, P4. The best treatments P7, followed by P3. P5, P8 for the production of dry matter and mineral uptake (Table 1) BACK

15 Introduction of legume on B humidicola pasture (P2- P8) was signifficantly different (P <0.05) increase digestibility of dry matter, VFA and NH 3, while digestibility of organic matter was the same among the treatment. The treatment which combination of NPK fertilizers with manure and potential microorganism (P7, P8, and P5) were significantly different (P<0.05) increase digestibility of dry matter, VFA, and NH 3 as compared with Control (Table 2). BACK

16 Total VFA that yield in this study about mm, is sufficient for the optimal growth of rumen microorganism. Total VFA from single feed with legume browse plant was higher than legume browse mix with grass (Astuti, et al., 2011). BACK

17 According to McDonald et al. (2002), the range of NH 3 optimal concentration to synthesize the rumen microorganism s protein was 6 21 mm. The NH 3 that yield from protein fermentation on the experimental was in optimal range for the growth of diary goat and not excessive. BACK

18 Conclusion The introduction of legume on B humidicola pasture increased dry matter production, mineral uptake (N, P, K, Ca, Mg), digestibility of dry matter, VFA and NH 3 (P 3 -P 8 ),. Dry matter production, mineral uptake in treatment with half doses of inorganic fertilizer, manure and potential microorganisms (P 3 -P 8 ) were higher than only using inorganic fertilizer (P 2 ) and Control (P 1 ).

19 Treatment of P 7, P 8, P 2 and P 5 increased DM digestibility, VFA, NH 3 was compared with control. The best treatments in this research were P 7 (B. humidicola pasture with P. javanica and C. mucunoides) and followed by P 8 (B. humidicola pasture with P. javanica, C. pubescens and C. mucunoides).
