Zoetis introduces mycoplasma hyopneumoniae management programme




Zoetis has introduced Mhp Guardian, the first comprehensive mycoplasma hyopneumoniae (Mhp) management programme that moves Mhp-positive swine herds into a negative or more stable status and keeps them there.


Mhp is one of the most prevalent and economically significant respiratory pathogens in the swine industry. Pigs of all ages are susceptible, but pigs typically become infected in the first few weeks of life either from the sow or from other pigs after commingling.


"Pigs with mycoplasma pneumonia will have a dry hacking cough, and as a population, they become very lethargic and lack the activity level of a healthy group of pigs," said Dave Baumert, senior technical services veterinarian with Zoetis Pork. "Subsequently, we see decreased average daily gain and feed efficiency. In addition, the producer is paying for increased medication costs and higher facility costs because Mhp-infected pigs will take longer to reach a target market weight."


Mhp-positive pigs average 9.2 pounds lighter and on average need an extra six days to reach market weight. Overall, the economic impact results in a loss of US$2.00 to US$5.00 for Mhp-positive pigs.


Mhp, in combination with a respiratory coinfection such as porcine reproductive and respiratory syndrome virus (PRRSv) or influenza A virus of swine (IAV-S), can cost producers over US$10 per pig.


Mhp Guardian is the first consultative, comprehensive Mhp management programme that moves Mhp-positive herds into a negative or more stable status. It offers pork producers (in collaboration with their veterinarians) a step-by-step approach that helps guide their operation through a herd status identification process and delivers a customised road map for either a control or elimination programme, depending on their specific goals or objectives.


"The Mhp Guardian programmehas four steps – the first step is to establish herd status using STOMP PLUS®, our consultative diagnostic service, to classify each site or farm as positive uncontrolled, positive controlled, provisionally negative, or negative," said Eva Jablonski, a senior technical services veterinarian with Zoetis Pork. "The second step is to assess intervention options. Using a risk management model, we determine whether control or elimination is the best fit for your operation and then build a customised, practical plan for your operation.


"Step three is implementing those intervention strategies – this is the nuts and bolts of getting it done. We'll work with you to develop a customised roadmap, taking into consideration system constraints, pig movement, etc. Lastly, step four is monitoring intervention outcomes. We'll work with you to develop a refined diagnostic plan to ensure the intervention was successful and to continue measuring stability."


Production personnel and pig caregivers are supported throughout the programme by the Zoetis on-farm pork production specialists and technical services team, who have extensive, real-world Mhp-management and research experience.
