A recent summary for the USA showed that from 1993 to 2022 litter size has increased 1.1%/year which equates to 3.15 pigs per litter or a 37.9% increase (Langemeier 2023). Increasing litter size...
Pharmacological levels of Zn (i.e., 2,000 to 3,000 mg/kg) is often included in diets for weanling pigs to prevent post-weaning diarrhea. However, pharmacological levels of Zn may reduce microbial phytase efficacy by chelating the phytate molecule, which subsequently prevents...
It is important that the digestibility of Ca in Ca sources is known to formulate diets based on values for digestible Ca rather than total Ca. Only a small amount of the Ca required by pigs is provided by...

Introduction
A common procedure for vaccine administration for pigs has been the needle-syringe device, with intramuscular administration. However, this method is considered to be potentially painful to animals 1,2. As a consequence of a painful vaccination process, the animals...
Abstract
Morbidity and mortality of respiratory diseases are linked to airway obstruction by mucus but there are still no specific, safe, and effective drugs to correct this phenotype. The need for better treatment requires a new understanding of the basis...
Introduction
Mycoplasma hyopneumoniae (Mhyo) is the primary agent involved in enzootic pneumonia (EP) and one of the leading agents involved in porcine respiratory disease complex (PRDC). EP carries a highly significant economic burden as it reduces average daily weight gain,...
