Background and Objective: In Indonesia, there are three dominant breeds of dairy goat in the hand of smallholder farmers. These are Etawah crossbred, Saanen and Sapera but the most common breed in Yogyakarta is Etawah crossbred goat. The main goal of dairy goat production is to improve traits related to milk and reproduction performance. The study aimed to compare milk production and composition of three crossbred dairy goats namely Etawah crossbred, which in Indonesia is called Peranakan Etawah (PE), Saanen-Etawah crossbred or Sapera and Saanen-Etawah Crossbred-Gembrong or Saperong raised under smallholder management in the tropical condition of Yogyakarta. Materials and Methods: The study was conducted in CV. Marlin Brothers dairy goat farm and in a farm belonged to a farmer group located at Turi, Sleman, Yogyakarta. Data were collected from goat in their 2nd-3rd period of lactation during 2 until 3 months after kidding. Goat feed consisted of Pennisetum purpureum dwarf and Calliandra calothyrsus added with a mixture of wheat pollard, copra meal, soybean meal, corn bran and minerals. Water was given ad libitum. The data obtained were statistically analyzed used one-way ANOVA (p<0.05). Results: Milk production of Saperong goat was the highest (p<0.05) in compared with Sapera and Etawah crossbred goats, on average were 1750.70±73.83, 1674.00±122.77 and 1340.00±76.38 mL/head/day, respectively. The total solid, lactose and milk fat of Etawah crossbred goat with average value of 15.42±0.04, 5.97±0.03 and 5.80±0.28%, respectively, were higher (p<0.05) than those in Sapera as 13.59±0.07, 5.59±0.02, 4.30±0.01% and Saperong milk as 13.35±0.02, 5.83±0.04, 4.25±0.035%, respectively. In the opposite, milk protein of Sapera and Saperong was higher than Etawah crossbred goat, with average of 3.71±0.03, 3.75±0.05 and 3.64±0.01% (p<0.05). Conclusion: In term of milk production, Saperong was better than Sapera and Etawah crossbred goats, but Etawah crossbred produced the best milk composition among those crossbreds of goat in small farms of tropical condition.
