Jane Jordan Pig World December 2017
In her second report from Applied Bacterial Control (ABC) AND St David’s Poultry team study tour, Jane Jordan explains how the significant reduction in antibiotic use in the Netherlands is being managed at farm level, and some of the costs and benefits of doing so.
The introduction of tough regulations governing all prescribed medications used on farm in 2011 has undoubtedly increased Dutch pig production costs. This has forced some businesses to quit production, while others find the regulated framework has hampered opportunities to diversify, differentiate and/or add value. But further integration, increased dialogue with retailers and consumers and brand development have flourished as healthy pigs, traceable production, low or no medicine use and good welfare are proving value USPs.
Heyde Hoeve (HH) is a co-operative that now operates its own supply chain producing premium standard, sustainably produced pigmeat. Based at Nuenen, near Eindhoven, the business uses Duroc-based genetics and a welfare-led, forward thinking management system that protects resources and earns a fair price. “We must alter perceptions and focus on achieving a sustainable supply chain,” said HH director Tiny Schepers. “We are not focused on higher productivity and producing cheap food. Our livestock industry must adopt similar principles to improve economic returns and secure its future.”
His 4,000-sow breed-to-finish operation is a ‘model unit,’ where community interaction is encouraged. Disease prevention is central to herd management and the farm works to a strategic health plan overseen by consultant vet Rijk Janssen.
Antibiotic reduction is a principal objective, as preventing disease and minimising medication fits HH’s sustainability ethos and offers significant marketing advantages.
The HH co-op implements routine vaccination programmes for endemic problems, such as porcine circovirus type 2 (PCV2), and maintains a stringent hygiene policy with vigorous infection control measures aimed at breaking disease cycles.
“A good example is the introduction of a specific gilt rearing unit on the Schepers unit,” said Mr Janssen. “Replacement females are now managed separately away from the finishing herd and this has improved the health status of young animals moving into the breeding herd. It has stopped the recirculation of pathogens from the finishing pigs back into the sow population.”
The business has also introduced a reporting schedule for all departments, which monitors daily trends such as feed and water intake. Any ‘concerns’ are noted, and, if necessary, actions are taken to preclude the potential breakdowns.
Mr Janssen believes this tough stance on AB reduction has encouraged pig producers and vets to re-establish good basic husbandry techniques and identify how ill manifests.
“Being more proactive will allow producers to manage health more effectively and reduce the need for ‘mass medication.’ This concept is becoming increasingly evident throughout the Dutch pig industry, because it works,” he said.
Sanitised solution define disease control
Rene Weijs manages a commercial 3,200-place finishing business, which takes pigs from 27 kg to 110 kg. It is part of 750-sow pig production and vegetable enterprise he runs with his brother.
The unit has undergone significant refurbishment to improve environmental controls and water quality, with the objective of further improving health status and reducing production costs.
A bore hole supplies water to the farm and significant investment has been made in the filtration, purification and delivery system. The pigs’ drinking water is now supplied via three colour coded water lines: fresh (blue), acidified (red) and with vitamin/mineral supplements (green). Another separate washout line serves the farm’s pressure washing and disinfection system. Banks of pipes and valves are also located in the corridors outside the finishing rooms to allow independent control of water supplies. Medication can now be delivered accurately to individual rooms, while the business can also explore alternatives in water treatments, such as organic acids and nutraceuticals.
“Ileitis has been a persistent problem and was previously managed using routine medication,” Mr Weijs said. “Producers still need methods that can safely and effectively medicate groups of pigs with antibiotics if they are sick. Dosing water supplies is efficient, strategic and accurate but water supplies must be clean and of a consistent quality.”
His business has strived to minimise antibiotic use, preferring to solve problems through proactive disease prevention (vaccination at weaning), improved husbandry and better management. AB use has remained below 10 ‘Defined Daily Doses per Animal (DDDA)’ since regulations were introduced in 2011. Current records show AB use in 2-4 DDDA and ileitis is under control, which Mr Weijs believes is hardly due to the sanitised water supply and routine use of acids and gut conditioners supplied via drinking water.
Mr Weijs has been encouraged to feed finishers a course of grist meal, delivered ad lib through wet/dry feeders. Three home-mixed diets are used and pigs are blend fed to create a range of specifications more closely matched to their requirements through their growth curve, helping optimise lifetime performance and feed conversion ratio, and reduce feed costs. His slaughter pigs are currently averaging between 850g- 900g ADG with an FCR of 2.35.
The Dutch approach to AB reduction has forced change, but most UK vets would not like a regulated system, said Richard Turner, director of St David’s Poultry Team and its arm launched to find alternatives to antibiotics, Applied Bacterial Control (ABC). “The Dutch system has loopholes, which potentially could allow for some abuse. “To have a tight regime there needs to be more testing of final product and I am more inclined to favour a system that is industry and retailer-led rather than a prescriptive government system,” he said.
Vets, he said, must be able to present a range of cost effective protocols and solutions that would support farmers during the transition period, something the Dutch policy has not achieved in its early stages.
ABC vet Charlie Carslake highlighted what he felt was a ‘heavy handed’ initiative. “I would prefer to see a more balanced approach used here, offering good levels of support and some funding,” he said.
He did, however, support the transparency of the Netherland’s AB initiative and its data recording and benchmarking, particularly between individual farms within a single practice. “A unified national database detailing usage between both farms and vets in the UK would be very valuable,” he added.
