Animal health status a ‘clear driver' of sustainability levels
This was the clear message the vet delivered to the recent Northern Ireland Institute of Agricultural Science (NIIAS) annual conference.
He specifically referenced the link between animal health and the issues of production efficiency, carbon footprint, and medicine usage.
Moreover, he said these are all matters that determine the overall sustainability of farming and food at the present time.
Dr. Strain is the chief executive of Animal Health and Welfare Northern Ireland (AHWNI).
In his presentation to the NIIAS conference, he confirmed that animal health status has an overarching impact on livestock performance.
In other words, an animal's genetic potential will never be fully reached if its health status is compromised, irrespective of the nutritional regimes that are followed.

According to the vet, clear links have also been confirmed between animal health status, production output, and the associated impact on the environment.
Dr. Strain explained: 'Between 2007 and 2017, milk output in the United States rose by 24.9%.
'However, greenhouse gas emission levels only increased by 1% during the same period.
'Analysis of these results has clearly shown that animal health status is a clear driver of whole herd efficiency and sustainability levels.'
The AHWNI representative highlighted the need for calves to be tagged as early as possible. This is a key requirement, linked to the ongoing bovine viral diarrhoea (BVD) eradication programme in Northern Ireland.
Dr. Strain also noted that further legislation will be required to allow for the full completion of the BVD measure.
Animal health
Animal health standards are directly linked to the usage of antibiotics within production agriculture.
He also confirmed that a specific disease breakdown predisposes animals to other health-related issues, which in turn can lead to increased antimicrobial usage.
He added: 'There is a tremendous level of interaction between diseases. For example, BVD predisposes animal to pneumonia. Infectious disease move within animals.
'But simple steps taken by farmers to tackle one specific issue can have repercussions across other aspects of animal health.
'For example, improving hygiene standards in calving areas to reduce the prevalence of Johne's disease will also act to reduce scour levels in newborn calves.'
Dr Strain also spoke of how improving animal health can have benefits for efforts to reduce carbon emissions.
'There is also a clear line between improved livestock health standards and the carbon footprint generated by a livestock farming business,' the AHWNI representative said.
'For example, reducing lameness problems within dairy herds will significantly reduce greenhouse gas emission levels.
'And reducing parasite burdens, such as those created by fluke and worms, will also deliver overall reductions in carbon footprint values.'

Mairead McGuinness withdraws from presidential election
Former MEP and European Commissioner Mairead McGuinness has withdrawn from the presidential election citing health reasons. Last month, McGuinness, who started her career as an agricultural journalist, secured the Fine Gael nomination to run as a candidate to become President of Ireland. In a statement released this afternoon (Thursday, August 14), McGuinness said she had made the "very difficult decision to withdraw my name as the Fine Gael nominee for the presidential election". "This decision is not lightly taken and follows a stay in hospital last week. "My priority now is my health. Given that the election is in a short couple of month, I do not believe that I have the strength to give the campaign my all. "I am taking this decision on medical advice and and while it is extremely difficult, it is the right decision for me and my family," she said. "I appreciate that this will come as a shock and disappointment to party members and colleagues in Fine Gael, but our political family is strong. "I have spoken with the Tánaiste and [Fine Gael] party leader, Simon Harris, and thank him for his support and understanding. "I also want to thank all of those people who have done so much to support me, now and in the past. "My focus now is my health and my family, and I ask for privacy in the time ahead," McGuinness added. Tánaiste and Fine Gael leader Simon Harris said that "Mairead McGuinness has made an incredible contribution to public life in Ireland and in Europe". "It was our clear view in Fine Gael and the view of many people across Ireland that Mairead would make an excellent President of Ireland. Mairead's health will not now allow this," he said. "This has come as an awful shock to us all. Mairead is a valued member of our Fine Gael family. "It is absolutely essential that she now prioritises her health and I know I speak for everyone when I wish her all the very best on that journey," he added. The Fine Gael leader said that in the coming days the party's executive council will gather to "consider further the presidential election". "But that's for the time ahead, not for today. Today I want to pay tribute to Mairead. "I want to thank her for all she has done. I want to wish her and Tom and their family all the best at this time and she knows we are all sending her our very best," Harris said.

TB in focus: Record high reactors, soaring costs and the impact on farmers
Latest national bovine tuberculosis (TB) statistics show reactor numbers have hit a high of 43,290, while total expenditure in the first six months of this year has soared to more than €52.01 million. But behind the statistics is the very human cost of a TB outbreak on farm families, who have to put their daily lives on hold and then live with the fear that persists once a farm is declared TB-free. This week Agriland's special focus - 'Silent spread- Ireland's TB battle' - will examine the devastating cost of the disease, both economically and emotionally, and how the TB challenge may shape farming in the future and government spending. We visit one Kerry dairy farmer who lost his entire herd to the disease and find out how he rebuilt his herd. We also find out how other countries have adopted new policies and a 'strengthened partnership approach' in their campaigns to eradicate TB and how they are dealing with the persisting challenge of the disease. During our special focus week on TB, Agriland will also examine why enhancing genetic resistance to the disease can significantly "reduce the number of reactors, minimise herd disruptions, and lower costs". We also speak to the experts who are on the frontline of the battle against TB and find out what the latest research is telling us about the spread of the disease and what may be some of the key elements that might work when it comes to finding a solution. Millions of euro has been spent on research and on compensation to farmers in Ireland, but the current approach has not halted the spread of the disease or prevented herd breakdowns. However Minister for Agriculture, Food and the Marine, Martin Heydon has said he will unveil a new "action plan" to deal with rising TB levels in Ireland. Last month, Minister Heydon said he had secured "approval and support of my government colleagues to address the current high level of bovine TB". "My ambition with the bovine TB programme is to protect all farm families, those who are dealing with a bovine TB outbreak and those who are trying to keep their herds free from bovine TB," he stated.

Meet the bald Co. Louth Dexter calf
Farmer Andrew Matthews from Tenure in Co. Louth was shocked when one of his Dexter cattle gave birth to a rare bald calf, with only two small tuffs of hair where his horns should be. Matthews told Agriland that it is three weeks since the bull calf was born, adding that he is "doing brilliantly". The farmer said: "Other to no hair, the calf was completely normal at birth, proving to be an easy calving". Matthews farms a herd of pedigree Dexters for breeding and beef. This in itself is relatively rare, with the organisation Brave Herders estimates there is only approximately 3,000 head of Dexters in Ireland. According to Matthews, the calf was not born premature, and is only slightly smaller to the rest of the herd, with mature Dexters only standing at about 1m in height. He added that the calf stood and drank from the mother promptly. The farmer explained that the calf was kept inside for the first week under a heat lamp, but since weaning it off that, the calf is now "living its best life outside". The farmer explained how he brought the mother and calf back into the shed each night for the calf's first two/three weeks, as well as keeping it in by day during the extreme heat two weeks ago. The calf wears a jacket around the clock, and will realistically be in one for the rest of his life, according to Matthews. He added that this is the mother's fourth calf, highlighting how her offspring has never had any abnormalities up until now. The farmer said the calf was given vitamin injections and tested clear for BVD. He told Agriland that he is applying cream to the calf's legs to prevent them from getting sore or cracking. The calf still has no name, however Matthews joked about calling him 'Fluffy' or ''Streaker'. On his farm, Matthews also has a dun Dexter, which - while not exceptionally rare - are typically uncommon in the breed.
