L to R: Dr. Noel Kavanagh, Emmet Costello, Trinity College Dublin/Research Motor Neurone completing his PhD in Neuropsychology and Pat O'Callaghan, Managing Director, Interchem (Ireland) Ltd 

On the 24th June, 29 Interchem staff members completed a 300km virtual charity challenge. Individuals either walked, jogged or cycled over the course of 1 hour to complete the challenge, virtually from all corners of the country and some socially distancing from Interchems office in Dublin. Even though the team were apart, the team spirit was very strong, keeping in touch via WhatsApp. The Interchem team and Research Motor Neurone Charity have had a tremendous amount of support from customers, suppliers, family and friends, raising over €5,000 which Dr. Noel Kavanagh are very grateful for. Dr Noel Kavanagh., MVB, DPM, MAE, DECHPM, FRCVS. lives in County Meath with his wife Caroline. Noel is a retired vet and specialised in pig medicine. He was diagnosed with MND in December 2018. Noel qualified in veterinary medicine in 1969. Qualified as a specialist of the RCVS in 1984 and was appointed Chairman of the board of examiners in Pig Medicine of the RCVS. Awarded a Fellowship of the Royal College of Veterinary Surgeons (FRCVS) by thesis in 2002. He is a founding member of the European College of Porcine Health management, a practising member of the Academy of Experts and author of the textbook entitled “Maximizing Pig Herd Health, Management and Production Efficiency.  Former owner of Oldcastle Laboratories, providing Analytical Laboratory Services in the areas of Animal Health, Food Safety, Animal Nutrition, Toxicology and Environment Control.

VOICE BANKING 
"Following my MND diagnosis I was advised that I would lose the ability to speak I commenced banking my voice in January 2019 with ModelTalker.  Voice banking involves recording a list of 1600 sentences on a computer. When sufficient recordings have been captured, software chops them up into individual sounds (phonetic units). A synthetic voice is then built out of these phonetic units. I banked my voice in English on ModelTalker and French on Cerevoice.   
This was very important for me because a voice is a very personal thing and being able to keep this aspect of one’s individuality and identity is vital,  I now use my iPhone or iPad for communication, so I’m not totally isolated.  I type what I want to say into Predictable, which is the interface between the user and ModelTalker on my iPhone or iPad. Predictable then uses my ModelTalker voice to speak.  I have WhatsApp and email groups so that I can keep in regular contact with friends.  I use FaceTime, ZOOM and other video conference programmes for virtual meetings. 
They work best if I have someone is with me so that we can more easily keep the flow of conversation going, otherwise there is a lag period whilst I am typing. I am fortunate that my wife Caroline supports me 24/7 and our daughters Kirsten and Naomi and husbands John and Mathew and grandchildren keep in constant contact by WhatsApp, Facetime and Zoom. "

Timing of administration is based on the animal’s exposure to the parasites. This is usually 4-6 weeks post turnout, when the life cycle of some of the major influencers such as Cooperia Oncophora and Ostertagia start to take hold. Farmers have acknowledged issues of ‘coughing cows’ over the past number of seasons. This is particularly evident in heifers and 1st calved cows which have had limited exposure to parasites.

With higher stocking levels, earlier and later grazing seasons and young stock now being reared off the main grazing platform, exposure to certain parasites is on the increase. Early season parasite control at grass has proven to benefit financially in respect of milk yield (Gibb et al, 2005) who demonstrated a milk yield response of +1.68 kg/day solid corrected milk after treatment with Eprinomectin. Within the dairy sector we have a unique product available to treat most internal parasites that affect dairy cattle, Eprinomectin. Eprinomectin is a highly effective parasiticide developed as a broad-spectrum endectocide for topical treatment or recently available injection treatment of cattle of all classes and ages. It is the most recently marketed macrocyclic lactone in large animals. It has a zero milk withhold period for the use in lactating dairy cows.

The question is “Will this product remain effective in the treatment of my cows”?

Responsible use of Anthelmintic’s in Dairy Cows

The growing concern of anthelmintic resistance is not just a worry for sheep farmers. Cattle and dairy farmers are reporting that they are unsatisfied with the results achieved after worming cattle.

Regardless of the product of choice, it is important that the right dose of wormer is given correctly to ensure maximum efficacy. Literature has suggested that farmers could significantly delay the development of wormer resistance on their farms by worming correctly (Shalaby, 2013) Of critical importance is that the choice of wormer has no residual effect on the food product being produced thus choice of product must suit stage of lactation, for example, a zero milk withhold product allowing milk to enter the tank as normal.

What is Anthelmintic resistance?

A worm is considered to be resistant if it can survive exposure to the standard recommended dose of that particular chemical group of wormer*. Wormer resistance is heritable - the worm’s ability to survive is passed on to its offspring. Thus we need to prevent this happening.

What has happened?

The original guidelines for worm control were drawn up nearly thirty years ago. Since then the pattern of parasite infections has changed, as has the type of products available. All of these affect the way that we treat worm infections.

Climate change has brought wetter, milder weather fronts and increased grazing seasons with higher stocking rates has encouraged greater exposure to stock. Since temperature and moisture levels affect the development of infective larvae, this has also changed the pattern of worm populations. Due to milder winters, worms that do not survive well in very cold climates are now being found throughout Ireland. Infection by Cooperia (the small intestinal worm) is more common in cattle during the spring and early summer, whilst infection with Ostertagia (the small brown stomach worm) and Dictocaulus (lungworm) is often seen during the late summer and early autumn. Work published by Teagasc (2018) has highlighted the levels of which resistance has been found in some commonly used worming products on young stock. It would be determinantal to the industry if the likes of Eprinomectin was to follow suit.

What can be done?

Bulk milk test screening can give an indication of level of infestation in the herd and can help in monitoring the burden level. Faecal sampling gives greater feedback on individual animals and helps establish profiles for individual or small group treatments by age or stage of lactations. Lung washes conducted by vets are also becoming popular to monitor lung worm burden. Results from any sampling taken on farm should form part of the consultation with your veterinary advisor on herd heath planning and preventative medicine use.

A recent European Medicine Agency report, dated 21st April 2017 (EMA/CVMP/EWP/573536/2013) highlights findings and recommendations to reduce the issues surrounding anthelmintic resistance. It highlights that long-acting drugs (e.g. long acting boluses) and pour-on formulations pose a particular risk suggesting that Pour-on formulations may be associated with substantial variation in drug exposure, i.e. there may be the risk of suboptimal treatment due to grooming behaviour, dirty coat or weather conditions therefor adding to the development of resistance.

Another recommendation is the introduction of targeted selective treatment at farm level which ideally should include a post treatment check-up, This may have economic benefits and labour benefits based on routine screening. Farmers and their advisors should be prepared for possible legislation changes if the area of resistance keeps developing, for the time being it is important that farmers know what that are trying to treat, choose the correct product and ensure that the application of the product is accurate and does not pose a threat to the development of anthelmintic resistance.

The ‘take home’ messages and the practices to follow include:

  • Dose only when necessary
  • Use screening techniques such as milk sampling and faecal testing
  • Use an appropriate product
  • Give the correct dose rate
  • Administer the product in the right way
  • Consult your local veterinary surgeon for advice

Interchem has a strong range of diagnostic services available and this range has grown since the acquisition of IDT in January 2020.
Diagnostic tools are vital in preventative medicine, making it possible to get fast, accurate information about the health status of your herd. Please contact your vet for further information.
Interchem’s diagnostic services are as follows;
• Flu diagnostics (sow and piglet). What strain of flu are your pigs/ sows positive for? It may be more than one.
• Using the correct vaccine for the strain you are positive for will mean quicker results in terms of pig performance and will make it easier for your vet to prescribe a vaccine
• Actinobacillus Pleuropneumoniae (APP) diagnostics (piglet): Piglets are blood tested at varying ages. This will tell us when maternal anti bodies are no longer protecting your piglets, and therefore when the correct age to vaccinate is
• Mycoplasma Hyopneumoniae (MHyo) diagnostics: Mycoplasma Hyopneumoniae can be diag nosed through our CLP programme
• Salmonella diagnostics: If you would like to find out where the highest challenge of Salmonella is on your farm, Interchem’s diagnostics can help
• Oedema Disease diagnostics: Faecal samples and/or intestinal samples are taken to determine whether or not your pigs are positive for Shigatoxin and are suffering from oedema disease
• Anaemia/iron deficiency: As discussed in the Iron Deficiency Anaemia piece, Lisa is available as part of Interchem’s haemoglobin testing service
For more information on any of the above, contact your vet.

Lung program

One shot vaccine administered at 3 weeks of age. Single injection providing early and long-lasting protection. Broad stimutlation of the immune system with Imuvant™.
A lung score can be carried out in the factory prior to starting the vaccination programme and every 6 months thereafter to monitor pig performance. Progress and comparison reports throughout the vaccination programme are available from your vet or a member of Interchem’s Swine Team.

Synchronised production flow is the golden key for unlocking your pig unit performance. There are two approaches to production flow management.
1) Why we would want to have a synchronised production flow? What would it mean on our farm, if we are able to control the production flow and increase pig performance?
2) When and how do we do it? Are the staff on the farm able to follow the rules and develop systems that create consistency?
A consistent flow of gilts and sows to the farrowing house gives the best utilisation of production facilities. It is not possible to compensate for a lack of gilts/sows in one batch by loading more sows in the next batch. While a farm may reach the average targeted services and average targeted farrowings, there may well be a huge weekly variation. This leads to holding back sows which need culling, sows from different weeks in the same farrowing house and sows being weaned either too early or too late.
Appropriate gilt management is important for breeding efficiency and an increasing number of Irish pig herds are now synchronising their gilts. Synchronisation of oestrus in gilts in weekly managed systems improves the flow of breeding animals within different parts of the breeding unit. Planned number of gilts in heat for each particular batch allows having the right number of gilts at the appropriate age served every week which enables reduction of a gilt pool. Lower average age results in decreased cost per gilt in terms of housing and feeding expenses on
the farm.
Gilts are a massively important part of any pig farm and the management of these gilts is essential to ensure we get the most from them while being as efficient as we can. For example, many Irish pig farms have a larger pool of gilts than they need and when translated into money, this is where producers can make a saving.

Interchem’s Technical Specialist, Lisa Hopkins, is available to discuss how we can help you become more efficient when selecting and breeding your gilts – the future of your herd. Lisa will set your farm up on Repronomics and demonstrate how to get the best value and information from the tool.

 

Figure 1: Gilt service spread

Page 1 fig 2

Figure 1 shows how an Irish herd who are synchronising gilts were able to reduce their gilt
service spread from 7 days a week to a 2-3 day window thus allowing the staff to service gilts
on the same day as weaned sows and subsequently farrow on the same days.

 

To summarise

Synchronising production flow leads to; consistent and synchronised farrowing; significant cost saving from reduced and optimised feed consumption; increased sow lifetime performance and increased piglet quality at weaning.
In conjunction with your veterinary practitioner, additional support services can help pig producers in the development and management of production plans and production flow alignment solutions. A range of free technical services are available that are focused on providing high quality bespoke management tools for your specific production profile. A long term approach is taken that makes sure you are continually updated with key best practice developments, enabling you to truly benefit from implementing controlled and consistent gilt synchronisation.

Repronomics

Repronomics
Reproduction Economics

Repronomics is a farm management tool that focuses on how the reproductive performance of your sows and gilts effects the overall performance and ‘flow’ of your farm. An economic value and an efficiency percentage is calculated for your farm and this will highlight areas that require improvement, for example, farrowing rate, replacement gilts required, stocking densities etc. This tool is available, free, to producers on a gilt synchronisation programme with Interchem.

 

 Gleptosil pic

Piglets are born with limited iron reserves and require supplementation of iron for the prevention of anaemia and to build their immune system (1). Iron supplementation is performed routinely on commercial farms, however iron status of piglets is rarely evaluated.

Iron deficiency anaemia in the piglet can be manifested in one of two ways - clinical or sub-clinical anaemia.
Clinical anaemia is the more severe form and is characterised by a reduction in growth rate, lethargy and pale skin.
While the signs of clinical anaemia are easily recognised, sub-clinical anaemia may not be recognised at all. The producer may not realise their pigs are growing below optimum rates or see the negative effects that sub-clinical anaemia is having on feed conversion rates. In addition, they may not realise that their pigs have a much lower resistance to disease.

To be effective, the iron must be available for complete absorption within the body. If the iron is not completely absorbed, it is not available for utilisation. It is important to note that not all iron compositions are the same. Gleptosil contains gleptoferron. Over 95% of the injected gleptoferron within Gleptosil is absorbed within 24 hours, ensuring very high utilisation of the dose by the piglet with no staining at the injection site (2)

In summary, piglets require sufficient, high quality iron, not only to prevent iron deficiency anaemia, but to achieve their full growth potential by having a strong immune system.
Haemoglobin testing is a quick way of finding out if you have anaemic or iron deficient piglets in your herd. For more information or to arrange a haemoglobin test, contact Interchem’s Swine Technical Specialist, Lisa Hopkins on 086 701 3844.
