Raising hogs today is different than it was even a few years ago, as genetics have changed how producers need to manage the animals, according to John Sonderman, technical services manager for Danbred North America.
Sonderman discussed how genetic progress has changed the way producers need to feed and manage their hogs during the Alltech Symposium held recently in Lexington, Ky.
"Pork quality has changed a lot in the past 30 years--some from genetics and some from nutrition. We have to learn how to manage the hogs to achieve the most end product," he said.
Currently, sows average 5,412 pounds of carcass sold per sow per year, and one sow is marketing 25.65 pigs per year.
In order to continue the improvements in productivity, he said, different inputs are needed for pigs than used to be needed.
"With more pigs per litter, a sow requires more feed. A sow producing nine pigs per litter (ppl) requires 11.46 pounds of feed per day, with 11 ppl she requires 13.19 pounds per day and with 13 ppl she requires 14.92 pounds per day," he said. "We need to have better defined diets for sows to be able to maintain themselves while taking care of their piglets."
Sonderman said there are many factors that influence lactation and feed intake, including ambient temperature, body condition, parity, dietary energy, water quality and quantity, feed particle size, feeding frequency, health, feed palatability, number of piglets and sow comfort.
External challenges to the industry include animal welfare, use of antibiotics and the labor source. These factors all influence how pigs are managed also.
"We continue to get more and more technologically advanced, which allows us to gain emerging knowledge. Fetal imprinting can show us gene expression and help in a feeding program. Litter management is important to ensure all pigs are being cared for," he said. "Having a healthy gut and immune system can help fight diseases."
