This study aimed to improve the quality of feed to increase milk production of dairy cows at smallholder farms in Bogor Regency. Treatment for feed quality improvement consisted of G1: 16% crude protein (CP) concentrate + calcium fatty acid (Ca-FA); G2: 16% CP concentrate + without Ca-FA; G3: 12–14% CP concentrate + Ca-FA; G4: 12–14% CP concentrate + without Ca-FA (as a control), respectively. Experimental feeding was carried out for 3 months. The results showed that feeding of 16% protein concentrate and Ca-FA had a significant effect (P<0.05) on milk production vs control (G1 = 13.76 L, G2 = 10.16 L, G3 = 16.29 L vs G4 = 7.67 L), increased consumption of dry matter, protein, fat, and feed energy, respectively. Ca-FA supplementation had a significant effect (P<0.05) on Ca and P consumption only in cows received G3. Feeding of 16% CP concentrate increased protein intake so that the ration protein content increased to G1 = 14.25%; G2 = 13.98% vs G3 = 12.87%; G4 = 12.37%. In the current study can be concluded that diet improvement through the feeding of 16% CP concentrate and Ca-FA increased milk production by the increased consumption of feed nutrients.

Dairy cattle to be able to produce products optimally must be fulfilled in quality and quantity. The forage of livestock has an important role as a source of feed which also determines the quality and production of milk. In fact, forage production is not always continuous throughout the year, especially when entering the dry season. The supply pattern arrangement and the availability of forage will affect the feed supply in the dairy farming area in Central Java. This study aims to analyze the pattern of supply and strategy for developing forage on dairy farms in the location of dairy cattle in Central Java. Census was conducted in 5 active dairy farming cooperatives in Semarang Regency and Boyolali Regency. The results showed that elephant grass was the main source of forage for dairy cattle. Based on the results of the SWOT analysis, in the development of forage, the strategy is directed at continuity of forage production. The proposed strategy is the introduction of forage preservation technologies for agricultural food and waste (silage, amoniase and hay); Acceleration of strengthening quality, material, and extension methods for forage; Utilization of agricultural waste; Coordinating with the relevant office for permits for land use owned by Perhutani; Facilitation from related agencies/institution in improving technology and managerial farmers; Expansion of sustainable forage land areas; Introduction and understanding of the types of quality forage; and optimizing the utilization of cattle waste as compost.
