Zoetis has released an update of the comprehensive manual, "A Contemporary Review of Mycoplasma Hyopneumoniae Control Strategies," a 62-page booklet with 14 articles developed by swine-disease experts specializing in this pathogen. [Source: Zoetis 30 Sep 2020]

The revised booklet features an updated section on breeding-herd classifications and an entirely new section on fogging for controlled exposure to Mycoplasma hyopneumoniae (M. hyo).

Also known as enzootic pneumonia, mycoplasma pneumonia is a prevalent and costly disease caused by Mycoplasma hyopneumoniae (M. hyo). In damaging the cilia (tiny hairs lining pigs' upper respiratory airways), the disease exposes the respiratory tract to bacterial and viral infections and coinfections by other pathogens.

"Respiratory infection caused by M. hyo has been a well-known feature of swine production for decades," said Lucina Galina Pantoja, DVM, PhD, director, U.S. Pork Technical Services, Zoetis. "Despite a long acquaintance with M. hyo and its principal clinical manifestation, enzootic pneumonia (EP), some gaps in our understanding of the disease and its control still remain, and new information on diagnosis and management of M. hyo infection has emerged."

"The purpose of this review is to provide a comprehensive update on M. hyo," she added.

Video: WARNING! Rough Start To Breeding Season!!

WARNING! Sheep Breeding Season Begins With A Bang! Breeding season is officially underway at Ewetopia Farms, but it didn’t exactly start the way we planned!

This vlog begins with us sorting through our rams to find the perfect match for a customer’s breeding program. What should have been routine quickly turned dangerous when one of our more nervous rams panicked. In seconds, Arnie’s knee was injured, and then I was slammed hard onto the concrete floor — both of us taken down by one ram!

Thankfully, it was just bruises, but it’s a reminder of how unpredictable and powerful mature rams can be. Once we recovered, it was time to get back to the real work — the start of breeding season.

We sorted the ewes into four breeding groups (two Suffolk and two Dorset), checking parentage as they ran through the chute, deworming those that needed it, and setting aside thinner ewes for session two of breeding season in a month’s time.This staggered approach keeps lambing organized and prevents overcrowding in the barns.

From rogue rams to the excitement of new breeding groups, this episode is full of action. Stay tuned for the next vlog, where we’ll share how we chose the rams for each group!
