Update on supplements for liquid pig feed


t’s well known that liquid feeding provides some impor- tant benefits over dry feed in pig production, chief among them the capacity for producers to make quick diet adjustments and to more easily mix in new supple-

ments at appropriate rates. There are indeed many new sup- plements on the market these days that can be put into either liquid or dry feeds but, while the practice of liquid feeding is extremely widespread in Western Europe, it’s cur- rently limited in North America, according to Jan Bebber, di- rector of global marketing & supply chain at Ohly. “However,” he adds, “the high prices of dry feed, as well as the improved performance and health and well-being of the animals with liquid feed, have driven the increased use of liquid feed in North America.” Globally, the market for liquid feed supple- ments is expected “to grow at a healthy rate of about 5 per cent CAGR in the coming years,” reports Bebber, “with Asia Pa- cific expected to become the biggest market.” He also notes that as more countries push forward with reducing or com- pletely replacing antibiotic growth promoters, the use of sup- plements that replace antibiotics in liquid feed “will grow considerably in the next few years.” Dr Lan Zheng, swine tech- nical sales manager with BIOMIN America (Canadian head- quarters in Quebec), agrees that feed additives such as acids, probiotics and phytogenics in both dry or liquid form have gained more attention after producers started seeking alter- natives to antibiotics. He notes, however, that, depending on the type of production system, liquid forms of additives are preferred over powders for their ability to reduce gastric pH and enteric pathogens, and for their cost-effectiveness.

Looking back, Dr Lee-Anne Huber points out that that there has been a major change in focus in supplements for liquid pig feeds over the last few years. “Supplements for liquid feeds were developed years ago in the Canadian and Europe- an markets, mainly to boost digestibility,” notes the professor of swine nutrition at the University of Guelph in Guelph, On- tario, Canada. “More recently, with in-feed growth-promoting and prophylactic antibiotic use on the decline or banned completely, supplements are now more focused on gut health. They include probiotics, enzymes and other feed addi- tives that help in gut development, or to generate favourable

New products focus on gut and immune heath, addressing the reduced global use of prophylactic antibiotics.

metabolites such as lactic acid. Acids improve digestibility and also make the stomach environment less favourable for the growth of bad bacteria.” For his part, Dexter Abrigo, Southeast Asia Pacific marketing manager for Novus Interna- tional, believes that the use of organic acid in water may be the most common solution explored by the swine industry as antibiotic use decreases, and these substances have been well documented as having antibacterial and even antiviral properties. He points to a recent study in which various feed supplements, including those that contain fatty acids, were tested for their ability to mitigate viruses. The study, conduct- ed at South Dakota State University in Brookings, South Dakota USA, found that titers for all four viruses tested (Sene- cavirus A, Porcine epidemic diarrhea virus (PEDv), porcine re- productive and respiratory syndrome virus (PRRSV) and
