def __load_key_indicators(self, state: ZxhState) -> dict:
        self.push_msg(state, 'caption', '产仔分析,加载关键指标')
        res = self.dp.get_product_core_birth_report(state.get('pig_farm_id'))
        if res.code != 0:
            self.push_msg(state, 'reply', f'产仔分析,加载关键指标失败:{res.msg}')
            return {'messages': []}
        else:
            return {'data': ('parturition_analysis_core_indicators', res.data)}
