Reproductive performance of female buffalo (Bubalus bubalis) in Karanganyar Regency, Central Java, Indonesia

Abstract

Buffalo is a ruminant animal that has the ability to digest the high content of crude fiber feed. Furthermore, agricultural waste such as rice straw is a common buffalo feed in Indonesia, with high crude fiber content, helping farmers manage their agricultural waste. Despite the high availability of rice straw, buffalo population decreases in some areas in Indonesia. This study further aims to determine the reproductive performance of female buffalo in smallholder farms in Karanganyar Regency, Central Java, Indonesia. The research was conducted in April-August 2021 in Colomadu, Kerjo, Jumantono, Kebakkramat, and Karanganyar Districts. A survey method was used, whereby samples were collected through the census with 9 respondents with female buffalo that had given birth at least 2 times. The data obtained were then analyzed using descriptive and quantitative analysis in the form of mean and standard deviation. As a result, the value of service per conception (s/c), gestational length and days open (DO), as well as calving interval (CI) were 1.33±0.5, 297.7±38.8 days, 120.9±30.3 days 418, and 56±35.6 days, respectively. Therefore, it is concluded that the reproductive performance of female buffalo (Bubalus bubalis) on smallholder farms in Karanganyar Regency, Central Java, Indonesia is in good condition.
