Animal health is at the heart of sustainable livestock business

‘Healthy livestock produce sustainable food’ is a whitepaper launched by MSD Animal Health earlier this year, which highlights how good animal health maximises production for each unit of input, reduces greenhouse gas emissions and gives the industry a competitive edge in the global market.

Dr Paul Williams, MSD Animal Health technical manager (ruminants) and co-author of the paper, says:

The farming industry has worked hard in recent years to improve animal health and welfare, reduce antimicrobial use and improve consumer trust, all while driving productivity.

For any business to be sustainable, it has to be profitable and, within livestock farming, animal health is critical to this.

A healthy animal will produce a higher yield per unit of input, while having increased overall productivity and lifespan and, for the same reasons, also results in a smaller carbon footprint than an unhealthy animal, as more is produced for less resource use.

  • Economics

    The report explains that a maintenance cost of meeting an animal’s basic nutritional and health needs can be attributed to each animal before its production, pregnancy, lactation or growth are taken into account.

    If this maintenance cost can be spread over a higher level of production, such as more meat or milk, each unit will be cheaper to produce.

    In any system, whether extensive grazing-based or dependent on housing and cereal feeds, production per unit of input can be seriously impacted by poor animal health.

    It is estimated that 20%1 of animal production worldwide is lost as a result of disease.

    Sick animals perform less well than healthy ones and this is not only seen in reduced growth rates or lower milk yields.

    Reduced fertility, abortions, stillbirths, poor carcase quality and increased mortality all impact on a business’ economic viability and, therefore, its long-term sustainability.

  • Environment

    With climate change and its causes an increasingly important issue, the impact of livestock production on the environment is a source of much debate and dispute, both within the industry and among consumers.

    But what is clear from the report is that, regardless of production system, the relationship between animal health and economic viability also applies to environmental responsibility.

    In livestock systems, higher producing, faster growing animals need less land, water and fossil fuel for each unit of output.

  • Social acceptability

    Social acceptability can be difficult to define, particularly in this social media age, but what is clear is that consumers want a trusted food source and 94%2 of surveyed consumers believe it is important to protect the welfare of farmed animals.

    If livestock systems contain components which are likely to be morally unacceptable to a substantial part of the population, the future of that system is unlikely to be sustainable.

    In addition to the ethical reasons for maintaining good animal health, there are practical aspects linked to social acceptability.

    Food produced from livestock must be safe to eat with robust traceability and auditing protocols in place in which consumers can have the utmost confidence.

    In recent years the livestock industry has put in place improved animal husbandry, housing, hygiene and biosecurity practices, is breeding more disease resistant animals and vaccinating to protect them against future disease.

    The result is healthier animals which require less veterinary input and treatment, including using less antibiotics, preserving their use for when it is proven they are needed, which benefits the farmer, the animal and the consumer.

He says: “For my business, sustainability is all about producing as much home-grown feed as we can, which although not without a cost, means we are self-sufficient and do not need to buy-in any straw, cereals or forage.

We are a mixed farm with livestock, cereals and a free-range broiler unit, which not only spreads the risk, but means we have valuable muck available, which all goes back onto the land completing the cycle.

As well as improving soil structure and fertility, it also reduces the amount of expensive inorganic fertiliser I need to buy.

We operate a five-year rotation system using grass as a break crop. By managing the land well, it is more productive in terms of crops and providing good grass for livestock, keeping them healthy as well as keeping production costs down. This is particularly relevant when prices for finished stock are not good.

We take a preventative approach to animal health for sheep and cattle, as healthy animals are more productive animals and require less management input.

We have vaccination and disease surveillance programmes in place and will shortly be vaccinating calves against pneumonia and testing cattle for BVD.

We work closely with our vet on health planning.”
