Productivity, absence of a bull and endoparasitic nematodiosis in beef cattle farms in an upland area of East Java, Indonesia.

Abstract

Background and Aim:Cattle are an important economic asset for the rural community in East Java Province, Indonesia. The study aimed to provide updated data of cattle farm demography, productivity, as well as the role of the absence of a bull and nematodiosis in reduced productivity of beef cattle in an upland rural area of the province.Materials and Methods:The study was conducted in Sukowono village, Bondowoso region. A Census survey was conducted to collect data through interviews with farmers. Further, 102 fecal samples were taken systematically and processed using a double centrifugation method to investigate the endoparasitic nematodiosis in the cattle population. The demographic data, productivity, and nematodiosis were analyzed descriptively. The difference between proportions was analyzed using Chi-square with 95% confidence limit. The associations were described in risk ratio with 95% confidence interval (CI).Results:The total cattle population was 814 heads; the range of farm size was 1-7 (median: 2) cattle. Female cattle comprised 81.8% (666/814) of the cattle population but, only 5.5% (23/422) farmers kept both bull and mature female cattle. Pregnancy rate was 26.8% (145/542) of mature female cattle. The delayed first calving time appeared in 24.8% (62/250) of heifers and calving interval of >14 months occurred in 83.2% (149/179) of multiparous cows. The prevalence of endoparasitic nematodiosis was 43.1% (44/102, 95%, CI: 38.1-52.1%). Either the absence of the bull or the nematodiosis did not associate with pregnancy rate or calving interval of cows.Conclusion:This study indicates that the productivity of the cattle in the study area was low but may not associate with the absence of a bull or nematodiosis.
