Slide 1Use of Indigofera zollingeriana as Forage Protein Source in Dairy Goat Ration
L. Abdullah, D. Apriastuti & T. Apdini
Bogor Agricultural University
– Feed cost-milk price ratio = 1 : 3-4
– Increase farmer income (Rp. 4.215.000/month for 5 lactating does)
– Increase national goat milk population 11.2% within 2005- 2007 (DGLAH statistic, 2008)
Economical prospect of dairy goat business in Indonesia
Significant Problem in Dairy Goat Production System
– Milk production still low only 45-73% of genetik potential (average 1.5-1.8 L/day/head)
– Low quality of feed at farmer level
• Based on non perishable local forage (easy to be rot, bulky, difficult to transport)
• Forage protein supply (<7-11%) to low for dairy goat
– Concentrate cost increase high import feed stuffs (for protein source)
Strategic Approach
– Increase supply and use of high quality forage (legume) like Indigofera
– Improve utility value of high quality forage
– Business/industry development for high quality forage, based on local species
High forage production Easy to grow High reproductive High quality forage Drought stress tolerant Improve soil P and N
Indigofera zollingeriana
• Water content: 10-12%
• Crude protein : 27-31%
• Crude fat : 2,9-3,4%
• Crude fiber : 13-14%
Indigofera Plantation Model
Foliar fertilizer preparation : mixed with goat urine (1.25L) and mineral nutrient solution (8.75L)
Forage harvesting, let the trunk height 1 m for regrowing

Objectives
• To improve nutrient content of ration at farm level, particularly protein content
• To improve milk production and milk production persistency during a month before dry period
Materials and Method
• Feeds
– 60% elephant grass + 40% commercial concentrate (CF) daily feed of the farm
– 60% elephant grass + 40% pellet Indigofera leaf (PIF)
• Feeding
– Feeds were given during a month prior end of lactation
Parameters
• Feed digestibility,
