Welcome to the <strong>June</strong> edition<br />

of your newsletter!<br />

As I write this I’m sat in the office on<br />

a peaceful Tuesday morning with a<br />

coffee in hand…the birds are singing,<br />

I’ve had a McDonalds breakfast,<br />

Liverpool won the Champions League<br />

for the sixth time on Saturday night<br />

(Come on The Reds!!) and the first<br />

episode of this years’ “Love lsland”<br />

aired last night which both myself,<br />

Dan and the other girls in the office<br />

are extremely excited about! All in all a<br />

pretty good week so far!<br />

You’ve all been busy too these past<br />

few weeks, everyone’s been silaging,<br />

cows are out enjoying the weather and<br />

it feels like summer’s in the air which of<br />

course means show time! It was great<br />

to see you all out at Stafford Show<br />

last week – lovely to see some of our<br />

clients placing in the show ring too!<br />

Well done all! Coming up next we’ve<br />

got Derbyshire County Show, Newport<br />

and Great Eccleston - so see you all<br />

there hopefully!<br />

Before I sign off, I can’t possibly forget<br />

the party to end all parties! You are all<br />

very welcome to come and join us for a<br />

drink on Saturday 20th July to celebrate<br />

20 years of <strong>LLM</strong> (yes – Den, Bill and<br />

Charlie are really that old! Some have<br />

aged better than others…) There’s<br />

some more info about this on page 4.<br />

Somehow I’ve been roped into DJing,<br />

six years on from my last ever gig, so<br />

I’ll be dusting off my headphones for<br />

one night only – worth a laugh right?<br />

Look forward to seeing you all there!<br />

Also, this month we’re trying to do our<br />

bit with the global plastic problem -<br />

every little helps. Rob Howe gives us a<br />

very in-depth look at why dung beetles<br />

are good for farms. Dan Stevenson<br />

discusses scab in Ewes News and<br />

Steph highlights the benefits of worm<br />

egg counts towards combating wormer<br />

resistance.<br />

We hope you enjoy! And as always,<br />

any questions, give us a shout.<br />

Premier Fantasy Football League<br />

Well the <strong>LLM</strong> Fantasy Football is<br />

over for another year. It also sees<br />

the end of Den’s five year bet that a<br />

girl could not win it too.<br />

The winner for the 2018-19 season is<br />

Meg Richardson.<br />

Many congratulations to you Meg.<br />

Saved me having to pay Den any<br />

money to settle the bet!<br />

So the trophy stays in the Goodwin<br />

family going from Neil Goodwin to his<br />

niece Meg.<br />

It was a closely fought league with<br />

some changes in the top spot.<br />

Liverpool and Man City helping us all<br />

to rack up some points.<br />

Second place we had Scott Wainwright<br />

followed by Matt Haslam from <strong>LLM</strong>, in<br />

third place. The highest placed client<br />

was James Weaver in 5th place and<br />

then Peter Hughes in 7th place.<br />

Not long till we start the roller coaster<br />

of emotions with the Fantasy League<br />

all over again in August.<br />

Seriously the results can affect my<br />

mood but don’t let that put you off<br />

joining in to try and lift the trophy. Give<br />

us a call at Whitchurch if you want to<br />

join and we will give you the league<br />

code!<br />

Hazel<br />

Plastic Reduction Push<br />

You will no doubt be aware of the<br />

effects that plastic is having on our<br />

planet, in our oceans, on our wildlife<br />

and on human health too.<br />

There has never been a time where<br />

it has been more written and talked<br />

about.<br />

We have decided to do what we can<br />

to limit our practice’s plastic output.<br />

We hope you will join us as we need<br />

your help, ideas and understanding to<br />

reduce unnecessary plastic use across<br />

our business.<br />

8


What are we doing?<br />

1. Reducing our use of plastic bags for<br />

meds<br />

a. If collecting, feel free to bring<br />

your own reusable bag or box<br />

b. We will aim to use cardboard<br />

boxes we have deliveries in, instead<br />

of plastic bags<br />

c. We have sourced some recycled<br />

paper bags – please let us know<br />

what you think of the quality<br />

2. Getting involved in the community<br />

a. Recently, members of the<br />

practice in Lancashire organised<br />

a ‘mass unwrap event’ at Booths<br />

Supermarket in Garstang.<br />

b. Whitchurch are using a local<br />

dairy for milk delivered in reusable<br />

glass bottles.<br />

Both Hazel in Whitchurch & Rob in<br />

Lancashire have been putting their<br />

heads together to find ways in which<br />

we can reduce our impact as a practice.<br />

We hope you will be supportive of our<br />

efforts and get involved by giving us<br />

more ideas and solutions.<br />

If you have any ideas on this please<br />

give us a call.<br />

Dairy Talk<br />

Why are dung beetles<br />

so good?!<br />

It’s great to see stock out again at<br />

the start of what we hope will be a<br />

fantastic grazing & growing season.<br />

It is often easy to forget what other<br />

life is also working hard for us in<br />

our fields, such as the humble dung<br />

beetle (bee & earthworm among<br />

others!) Rob Howe unearths some<br />

facts...<br />

Did you know?<br />

There are approximately 60 species<br />

of dung beetle native to the UK.<br />

Worldwide, they are classed into three<br />

groups based on their poo-related<br />

behaviour.<br />

The most well known are the ‘Rollers’<br />

(Telecoprids). These make a dung<br />

ball and roll it away to be used as a<br />

food source or for brooding chambers.<br />

Rollers are tropical species, there are<br />

none in Britain.<br />

African dung beetles (above) can roll<br />

dung balls 50 times their own body<br />

weight, vast distances. These guys<br />

can use the stars of the milky way to<br />

navigate!<br />

In the UK we have ‘Tunnellers’<br />

(Paracoprids) and ‘Dwellers’<br />

(Endocoprids). Tunnellers dig, burying<br />

the dung up to 3 feet below ground,<br />

where they lay eggs and where<br />

their larvae can develop safe from<br />

predation. ‘Dwellers’ neither roll, nor<br />

burrow. They simply live their entire<br />

lives in manure, the lucky beggars!<br />

These guys are also found in the UK,<br />

pictured above on a local sheep farm.<br />

Every species has its own habits, which<br />

are important in that the more species<br />

you have on farm the better, since they<br />

work synergistically to provide their full<br />

array of benefits.<br />

Why are dung beetles so good for<br />

our farms?<br />

• Increase soil organic matter by<br />

dragging down dung (fertilises soil)<br />

• Improve productivity of the land<br />

(more grass)<br />

• Increase soil aeration & structure<br />

(through creation of tunnels)<br />

• Improve rainwater infiltration<br />

(reducing erosion & flooding)<br />

• Speed up dung removal (reducing<br />

numbers of nuisance flies,


parasites & therefore animal<br />

diseases, which further reduces<br />

need for treatments)<br />

• They are FREE!<br />

Money Saving Experts<br />

Dung beetles are estimated to save<br />

the British cattle industry £367 million<br />

a year, primarily by encouraging the<br />

growth of healthy grass 1 . Compare<br />

this to what is often quoted as the UK<br />

annual cost of BVD at £40 million a<br />

year and it is quite staggering!<br />

The true value of dung beetles is<br />

likely to be even higher than the<br />

estimate above, because despite<br />

many assumptions in modelling,<br />

they provide more services that were<br />

not included in this model such as;<br />

flood mitigation, increased carbon<br />

sequestration, increased biodiversity<br />

& reduced reliance on expensive<br />

wormers, fertilisers & pesticides.<br />

Under Threat<br />

You may have heard the news<br />

stories about rapidly declining insect<br />

populations. Dung beetles are in<br />

decline and like bees, are absolutely<br />

critical to farming productivity and our<br />

ecosystems.<br />

The use of avermectins is one of the<br />

biggest problems for dung beetles, and<br />

therefore, the benefits they provide to<br />

us. Check out your cow pats and see<br />

how many holes appear within a couple<br />

of days. They should be riddled with<br />

holes if you have a good population of<br />

dung beetles.<br />

It is likely these products will be<br />

subject to further legislation and<br />

reclassification in the future, so if you<br />

use them, it would be as well to begin<br />

to think ahead now.<br />

Fortunately there are plenty of effective<br />

alternatives available, many of which<br />

are also cheaper. Changes in chemical<br />

use could save a potential extra £1.36<br />

- £4.36 per cow each year according to<br />

the study cited earlier.<br />

What can you do?<br />

Remove unnecessary treatments.<br />

For example adult dairy & beef cattle<br />

should be immune to gut worm burdens<br />

so avoid treating adults. According to<br />

studies, simply not treating adult beef<br />

cattle for gut worms would save British<br />

farming an additional £6.2 million a<br />

Unfortunately, the active ingredients<br />

in many convenient ‘pour-ons’<br />

(avermectins) can be lethal to aquatic<br />

life, birds, and many insects including<br />

the critically important dung beetles.<br />

Not only are these active ingredients<br />

lethal at very low doses, but they also<br />

stick around in the environment for a<br />

long time.<br />

year! However, please speak to your<br />

vet to ensure adults are still protected<br />

against important parasites such as<br />

fluke and lungworm.<br />

Remember we offer our ‘Infectious<br />

Disease Check’ bulk milk monitoring<br />

service. It is one way to track fluke<br />

exposure. There are many other<br />

non-chemical ways to protect stock,<br />

including Lungworm vaccination and<br />

management strategies. For our<br />

beef herds & sheep flocks, we need<br />

muck samples to keep track of fluke<br />

and worm burdens and many of you<br />

have already taken up this monitoring<br />

service via our health plans.<br />

Solutions<br />

Our VetTechs offer a FEC monitoring<br />

service - find out more on page 13.<br />

Avoid products in the avermectin<br />

group between March & October when<br />

animals are grazing. These products<br />

are still useful but we should be aware<br />

their lengthy persistence in muck can<br />

have negative effects on the farm’s<br />

productivity.<br />

If we decide we need to use avermectins<br />

we can opt for sub-cutaneous routes<br />

since these reduce overall doses.<br />

Creating ‘sacrificial paddocks’ well<br />

away from water courses is another<br />

way to reduce their impact.<br />

Also keeping dogs out of rivers if<br />

they’ve recently been treated with spot<br />

ons.<br />

Want to do more?<br />

Parasite Planning<br />

Get in touch if you would like to know<br />

your worm burdens and manage this<br />

important area in a more integrated<br />

way. Our VetTechs can easily and<br />

regularly collect muck samples or you<br />

can drop them in. Your vet can use the<br />

information as part of a full parasite<br />

control plan that will likely be able to<br />

save you on treatments as well as<br />

increase farm performance in other<br />

areas by creating a much bigger, more<br />

diverse population of dung beetles<br />

that help reduce compaction, improve<br />

your soil organic matter, productivity,<br />

drainage, biodiversity and carbon<br />

sinking.<br />

Do a Dung Beetle Survey<br />

These are quite easy to do and one<br />

way to assess soil health. Interested in<br />

seeing how many dung beetles are on<br />

your farm?<br />

The “Dung beetle UK Mapping Project”<br />

aka DUMP (haha!) would be interested<br />

in knowing what you find (www.brc.<br />

ac.uk/irecord).<br />

Further Info<br />

With summer nearly here and the<br />

weather warming up it is important<br />

to worm your fat lambs effectively.<br />

If you have already wormed your<br />

lambs, are you sure your wormer<br />

has worked effectively? With<br />

increasing resistance to wormers<br />

reported across the industry, Steph<br />

is here to tell us more.<br />

It is important to test if worming is<br />

required by sending in regular faecal<br />

samples from at least 10 animals for<br />

a VetTech to perform a Faecal Egg<br />

Count (FEC) before you worm your<br />

lambs. It is useful to send in a follow<br />

up sample 14 days post worming,<br />

except if you have used those from<br />

the yellow group, “levamisoles” which<br />

is 7 days post worming. If this “postworming”<br />

FEC does not show a 95%<br />

reduction of worm eggs, then there<br />

is a resistance problem in your flock.<br />

Our SQP’s and vets will be able to<br />

advise you on the most effective and<br />

appropriate worming plan for your farm<br />

using your results.<br />

Resistance is a big problem. Ineffective<br />

wormers cost the sheep industry £84<br />

million a year including extra feed and<br />

time needed to get lambs to finishing<br />

weights.<br />

tails<br />

The use of faecal worm egg counts to reduce worm<br />

resistance.<br />

White group wormers (Benzimidazoles)<br />

are the most commonly used wormers<br />

against Nematodirus in lambs.<br />

However, they have 94% resistance<br />

on the majority of farms in the UK.<br />

Yellow wormers (Levamisoles) have<br />

68% resistance and 50% resistance is<br />

found in clear wormers (Ivermectins)<br />

with new cases of resistance being<br />

found in the newest worming group,<br />

the Orange wormers. With increasing<br />

levels of resistance, it is critical to<br />

plan ahead and prevent this causing a<br />

problem on your farm.<br />

The VetTechs are currently running<br />

an offer of a “half price post-worming<br />

FEC” when following a pre-worming<br />

FEC. The benefits of using regular<br />

Faecal Egg Counts:<br />

• Diagnose worm issues sooner<br />

– which will reduce production<br />

losses.<br />

• Estimate the level of infection –<br />

which will allow you to monitor the<br />

need to worm saving you time and<br />

money.<br />

• Allow you to target timing of dosing<br />

– improving the effectiveness of<br />

treatment and productivity.<br />

• Monitor whether treatment has<br />

worked – do you need to dose<br />

again sooner or use a different<br />

product.<br />

• Detect worm resistance.<br />

Ewes News<br />

Scratching that itch!<br />

Did you know that Sheep Scab can<br />

infect up to 60% of your flock before<br />

any clinical signs are seen? So<br />

it’s a pretty important condition to<br />

control. Dan Stevenson gets us up<br />

Sheep Scab, also called Psoroptic<br />

Mange, is caused by the mite Psoroptes<br />

Ovis. Infected sheep have an allergictype<br />

reaction to the presence of the<br />

live mites and as a result are intensely<br />

itchy. Eventually this causes wool<br />

loss and severe weight loss and can<br />

lead to death. The full life cycle of the<br />

mite takes 2 weeks and they can only<br />

survive off the sheep for up to 17 days.<br />

In the late 1980s sheep Scab was nearly<br />

eradicated through a programme of<br />

compulsory preventative treatment.<br />

Now, diagnosis of Sheep Scab is on<br />

the up with 167 confirmed diagnoses<br />

in 2018 compared to 52 in 2015, made<br />

by surveillance laboratories throughout<br />

Great Britain.<br />

Treatment and control has typically<br />

relied upon the use of clear wormers<br />

in injectable preparations, such as<br />

Dectomax, Cydectin and Ivermectin<br />

products. These have proved popular<br />

as they are widely available, are<br />

relatively easy to administer, do not<br />

require special handling training and<br />

are safe for the operator when used<br />

correctly. However, they are also<br />

used widely for the control of worm<br />

infestations. The use to control Scab<br />

is not specific and so whenever they<br />

are used in this way all parasites in<br />

the sheep are exposed to the product.<br />

While this might sound like a good<br />

thing it is rarely necessary and so<br />

has contributed to the development<br />

of worm resistance to clear wormers.<br />

Depending on the exact preparation<br />

used, some persistent action can be<br />

expected (theoretically up to 60 days<br />

in the case of Cydectin 2%) although<br />

two injections may be required for<br />

treatment (in the case of Ivermectin<br />

products).<br />

Over recent years we have been<br />

increasingly concerned within the<br />

practice about the possibility of Scab<br />

mites developing resistance to clear<br />

wormers. This may have manifested<br />

as persistent signs following treatment<br />

or recurrent disease. Unfortunately,<br />

we are often involved late on in these<br />

cases when several treatments have<br />

been tried with no success.<br />

A study published last year, in the<br />

Vet Record has confirmed that this is<br />

indeed the case. Mites were collected<br />

from four farms where resistance was<br />

suspected when infected sheep had


failed to respond to injectable clear<br />

wormers. These mites were then<br />

exposed to a clear wormer within the<br />

laboratory along with control samples<br />

of mites that had never been exposed<br />

to any treatment products. Worryingly,<br />

the mites collected from the four farms<br />

showed similar low levels of death<br />

when exposed to the clear wormer<br />

product as the control mites did when<br />

exposed to no product at all. This<br />

suggests that the product had little<br />

effect on the mortality of the mites from<br />

the farm outbreaks. The fact that the<br />

control mites (that had never been<br />

exposed to treatment products before)<br />

nearly all died on exposure to the<br />

product shows that it is still effective<br />

but that resistance had developed<br />

on the four farms as a result of overexposure<br />

to these products in the<br />

past. This was the first demonstration<br />

of resistance to clear products in the<br />

UK and it is likely that this represents<br />

some degree of resistance across all<br />

the clear products.<br />

Whilst this is not great news for the<br />

control of a disease that has serious<br />

economic and welfare consequences<br />

there are several things we can do to<br />

ensure effective Scab management:<br />

• If you don’t have Scab then talk<br />

to us about effective quarantine<br />

treatments and biosecurity to keep<br />

it this way.<br />

• If you suspect Scab then involve us<br />

early to make sure the diagnosis is<br />

correct. This way you will not waste<br />

time and money with ineffective<br />

treatments.<br />

• Dipping provides very effective<br />

treatment and protection for up to<br />

four weeks. There are increasing<br />

numbers of contractors offering<br />

fully licensed, mobile dipping<br />

services making this a realistic<br />

option. All of our clients having<br />

used these services, including<br />

those where clear wormer<br />

resistance has been suspected,<br />

have been very pleased with the<br />

process and results.<br />

Whilst Sheep Scab is on the rise and<br />

resistance to clear wormer products is<br />

here to stay there is much we can do to<br />

keep the disease under control on your<br />

farms. Please give us a ring to arrange<br />

a time to discuss your individual Scab<br />

control plan.<br />
