THE effect that sub-clinical disease and parasite challenge has on eating quality performance is clearly illustrated in results from the latest Australian Beef Eating Quality Insights Report released this week.MSA graded cattle comprised 54pc of all Australian slaughter animals for the 2022–23 financial year, using data collected by MSA graders, along with additional data from sources such as the National Livestock Reporting Service and further information such as animal disease and defects.Based on data from the five MSA processors, 280,000 disease and parasite-free cattle (green line in graph above) had an average MSA EQ Index of more than 60, compared to 90,000 impacted cattle (yellow line) with an average index score of 57.76.

本周发布的最新澳大利亚牛肉食用质量洞察报告的结果清楚地说明了亚临床疾病和寄生虫挑威胁对肉类食用质量表现的影响。MSA分级¹的牛占2022-23财年澳大利亚所有屠宰动物的54%，所使用的是MSA分级人员收集的数据。而其他数据来源自：国家牲畜报告服务以及其他更进一步的信息，如动物疾病和缺陷等。根据五个MSA处理商的数据，280,000头无疾病和寄生虫的牛（下图中的绿线）的平均MSA EQ指数超过60，而90,000头受影响的牛（黄线）的平均指数得分仅为 57.76。

Gender, feed effect

Data for disease status, feed type and gender shows male disease or parasite-impacted cattle were 0.7 and 1.2 MSA Index points lower than non-diseased, for grainfed and non-grainfed respectively.

性别、饲料效应

疾病状况、饲料类型和性别的数据显示，对于谷饲和非谷饲的雄性牛来说，其受疾病或寄生虫影响的，MSA指数分别比未受疾病影响的牛低0.7和1.2。

State breakdown

Based on the available data, 78pc of grainfed MSA carcases assessed in Queensland were classified as disease-free compared to 41pc of non-grainfed cattle. In New South Wales, 90pc of grainfed cattle were non-diseased compared to 88pc of grassfed. For grainfed, the most prominent health condition was pneumonia (4pc), while for non-grainfed carcases, the highest disease incidence was hydatids (6pc).In Victoria, 99pc of grainfed cattle were disease-free, and 87pc of non-grainfed. The main health condition in Victoria for non-grainfed cattle was nephritis (5pc).

各州的爆发情况

根据现有数据，昆士兰州评估的78%谷饲MSA动物个体被分类为无病，相比之下，非谷饲牛这一比例为41%。在新南威尔士州，90%的谷饲牛没有患病，而草饲牛的这一比例为88%。对于谷饲动物，最突出的影响健康状况的疾病是肺炎（占4%），而对于非谷饲动物体，发病率最高的是包虫病（占6%）。在维多利亚州，99% 的谷饲牛没有患病，87%的非谷饲牛没有患病。维多利亚州影响非谷饲牛健康状况的主要疾病是肾炎（占5%）。

Production cost impact

Average costs of potential lost opportunities by disease or defect condition per carcase were calculated, with hydatids displaying the highest cost, at $5.97 per carcase. Liver fluke cost impact averaged $4.14/carcase, liver abscess $4.33, pneumonia $3.75 and nephritis 62c/head. Compromised carcase weight was not included in the lost opportunity calculation.

生产成本影响

计算了每个个体因疾病或缺陷状况而失去的潜在机会的平均成本，其中包虫的成本最高，为每个体 5.97澳元。肝吸虫成本影响平均为4.14澳元/头，肝脓肿病为4.33澳元，肺炎为3.75澳元，肾炎为62澳分/头。受损个体重量不包括在损失机会计算中。

Hydatids incidence growing

The prevalence of hydatids varies across Australia. Tasmania and South Australia had little or no hydatid disease while other states tended to have regions often associated with poor control in farm dogs, the presence of wild dogs (carriers of hydatids), and to a lesser extent, foxes and other at risk intermediate hosts such as kangaroos or pigs.

包虫发病率呈上升趋势

澳大利亚各地包虫的流行情况各不相同。塔斯马尼亚和南澳大利亚很少或根本没有包虫病，而其他州往往有一些地区往往与农场狗控制不善、野狗（包虫携带者）的存在有关，在较小程度上存在狐狸和其他高危中间宿主例如袋鼠或猪。

Based on the disease and defect information, which represents approximately 20pc of the national slaughter, the incidence of hydatids in Queensland has increased from 11pc to 13pc and NSW from 5pc to 8pc within this most recent two-year period (2021–2023), compared to the previous period covered by the 2019–2021 report.

根据占比约全国屠宰量的20%的疾病和缺陷信息，并与2019-2021年报告的数据相比，在最近两年（2021-2023年）内，昆士兰州包虫的发病率从11%增加到13%，新南威尔士州从5%增加到8%。
