W elcome to this month’s edition of the CellCheck newsletter. This month our guest contributor is Alan Johnson, from Limerick RVL. Alan explains the Laboratory Proficiency Testing (PT) Scheme that is being delivered by Limerick RVL, which all private laboratories offering mastitis milk culture/PCR services are invited to participate in. One of the benefits of the PT Scheme is to allow labs to objectively validate their performance, and provide greater confidence to their customers in the standard of service. For more details, see Alan’s article. DAFM has also commenced collation of the 2016 bulk tank SCC data, from all of the processors. Once collated, analysis can commence on the trends in milk quality from the previous year. The establishment of the 2016 bulk tank dataset will also allow us present the 500 farmers in the country with the lowest annual average SCC with the CellCheck Milking for Quality Awards. Planning of a national award ceremony is already underway, and this year’s ceremony will be held on Thursday, 23rd of November in the Lyrath Hotel, Kilkenny.

National Milk Culture Laboratory Proficiency Testing Scheme

Alan Johnson, RVL, Limerick

C ellCheck promotes the use of milk culture and antimicrobial sensitivity as useful tools in the control of mastitis at cow and farm levels. At least eight private laboratories and the Department of Agriculture, Food and the Marine’s (DAFM) Regional Veterinary Laboratories offer this service to farmers, veterinary practitioners, service providers and the dairy industry. It is estimated that approximately 10,000 milk samples are cultured on an annual basis. Typically milk samples are submitted from clinical mastitis cases and sub-clinical mastitis cases identified by high individual somatic cell counts at milk recording. Samples also come in before drying-off cows, and these are mostly composite samples i.e. a mixture of all four quarters. In 2015 the CellCheck Technical Working Group proposed a project with the following goals: • To provide support to laboratories wishing to improve and standardise the quality of milk culture service offered. • ToassistDAFMinthemonitoringof antimicrobial resistance patterns. • To establish a national database of mastitis pathogens, and explore the possibility of centralising results and improving data access. In early 2016 all private laboratories were invited to complete an online survey designed to gauge the level of interest in this project, to assess the services provided by the laboratory, the methodologies used

for culture and sensitivity, the system for recording and reporting results and the current and planned testing capability. The response was good and interest in developing the project was high. Following this survey and a face-to-face meeting with laboratory personnel, a proficiency testing (PT) scheme was initiated, coordinated by DAFM. Milk samples inoculated with one or more mastitis-associated bacteria were circulated to each participating laboratory on four separate occasions during the year. Each laboratory was requested to culture the milk using their usual methods, record the result details and return a completed report within a two week period. In addition each laboratory was requested to carry out antimicrobial sensitivity testing on the final set of samples, but only if such testing was part of the normal routine. A scoring method was devised to summarise performance and an end-of-year report is currently being prepared for circulation to each participating laboratory. Most of the laboratories were not involved in a milk culture proficiency testing scheme prior to this, so they considered it a benefit to be able to objectively assess performance and the quality of their testing and in planning for the future. The 2017 phase of the project will involve a repeat of the 2016 PT scheme and the collation of the 2016 culture data from each laboratory. Initially, summarising the isolation rate of eachmastitis-

Currently, this data is only available for the milk samples submitted for culture to the DAFM laboratories, summarised in the All-island Animal Disease Surveillance reports. Collation of this data from private laboratories will add value to the national mastitis pathogen profile, and enhance the surveillance role that DAFM currently carries out. An aspiration for the future, subject to the granting of the necessary permission by the farmer, is to collate the data on a centralised database such as that operated by ICBF. This would establish an invaluable tool for farmers and their authorised service providers in support of farm level decisions on mastitis control.

Collation of this data from private laboratories will add value to the national mastitis pathogen profile, and enhance the surveillance role that DAFM currently carries out.

CELLCHECK TIP OF THE MONTH

Don’t delay, get started today! M any farmers will wait until most, or even all of the herd has calved before doing the first milk recording of the season……don’t wait! The sooner you start to milk record, the sooner you will identify infected cows that may not have any clinical signs. Early lactation mastitis is a high risk and dealing promptly with new infections will give you the best chance of curing them, and protecting the rest of the herd. Early milk recording will also give you invaluable information on the success of your dry cow treatment, and management of your dry cows and in-calf heifers. The CellCheck Farm Summary Report looks specifically at mastitis control during the dry period and at calving, but it can only do this for cows that have a milk recording within 60 days of calving. So to get maximum value from your milk recording, if you haven’t already done a milk recording this season, get started now! [Click here] for previously published tips

CellCheck Farm Summary Report:

1. looks at cows and heifers separately, so you can see any problems in different ages of animals calving 2. shows how many animals have picked up a new infection either over the dry period or at calving 3. calculates the percentage of cows cured over the dry period 4. gives both a short-term picture, as well as a running total for mastitis control over the entire dry period/calving period to date.

CELLCHECK TIP OF THE MONTH

You may think sometimes that milk recording is a luxury that you can’t afford ……in fact, you can’t afford not to! It allows you to react quickly to cows with high SCC-these cows may have no visible signs of infection, but they will spread infection within your herd, raise your bulk tank SCC and are losing you money. It is also the best tool you have to establish which cows are the most productive in terms of fat, protein and milk yields, and are ‘paying their way’. So don’t delay, get started today!

RESEARCH UPDATE

The impact of removal of the seasonality formula on the eligibility of Irish herds to supply raw milk for processing of dairy products. Caroline Fenlon, Luke O’Grady, Finola McCoy, Erik Houtsma, Simon J More M ilk sold by Irish farmers for manufacturemust comply with EU regulations. Under a unique derogation, Irish SCC data is also subject to a monthly seasonal adjustment, for four months from November to February. The rationale behind this seasonal adjustment was to take account of the seasonality of milk production in Ireland. However, recent research has shown no evidence of a dilution effect on SCC with increasing milk yield in Irish dairy cattle. Hence, as part of ongoing industry discussions on milk quality, the sustainability of the seasonality adjustment has been questioned. In order to inform these discussions and to inform any future policy decisions, the DAFM milk quality division requested that research be carried out to estimate the impact of removal of the seasonality formula on the eligibility of Irish herds to supply raw milk for processing of dairy products. This work was carried out by AHI, CVERA and UCD colleagues, using the 2013 national bulk tank SCC dataset as a sample scenario. Bearing in mind the limitations of the available dataset, this study showed that the modelled impact of such removal would be relatively minor. It was estimated that in the absence of the seasonality adjustment, an additional 0.7% of all herds would be liable for suspension, while an additional 1.3% of the national milk pool would be ineligible for processing. All of this work was written up and submitted for peer-review, and was recently accepted for publication in the Irish Veterinary Journal. To read the full paper, please click here .
