A favorable characteristic of goats is their prolific breeding; however, non-optimal husbandry practices can hamper the reproductive performance of goats. This study aimed to determine the fertility of Etawah grade does based on Milk Urea Nitrogen (MUN) levels and explored the factors affecting MUN levels. Materials and Methods: Forty does with a body condition score of 2.0-3.0, in their second lactation, milked once a day were used in this study. They had ad libitum access to concentrates and forage (legumes and jackfruit leaves). Milk was collected every morning during two estrous cycles. The MUN was measured by using urea analysis kit (urea FS). Feed composition was analyzed to determine the Crude Protein (CP) level and fertility was evaluated using postpartum estrus (PPE), Services per Conception (S/C) and Days Open (DO). The relationship between reproduction data and MUN was analyzed using correlation analysis. Results: The average MUN was 33.75±3.42 mg dL–1 and the average PPE, DO and S/C were 64.80±6.34 days, 120.10±11.4 days and 1.68±0.34, respectively. The MUN was negatively correlated with PPE, S/C and DO. Etawah grade does with a high MUN (37.73 mg dL–1) exhibited long PPE (72 days) and DO (133 days) periods, as well as high S/C (2.0). In contrast, Etawah grade does with low MUN levels had low PPE periods, DO and S/C. Conclusion: It was concluded that the MUN level was inversely related to the fertility of Etawah grade does.
