An Iowa State University Swine Nutritionist says improved feed efficiency has been key to maintaining the economic and environmental sustainability of pork production. “How to Improve Feed Efficiency” was among the topics discussed earlier this month as part of Saskatchewan Pork Industry Symposium 2018 Dr. John Patience, a Professor of Applied Swine Nutrition with Iowa State University, says there’s been tremendous improvement in feed efficiency over the past four decades.
Clip-Dr. John Patience-Iowa State University:
When I started this business 40 years feed conversions of 3.9 to one and 4.0 to one were not unheard of where now that same range of production, we’re getting feed efficiencies that would be down around 2.5, 2.6 so a huge improvement by our industry and a test to our pork producers and their focus on becoming more efficient, becoming better producers, becoming more environmentally cognizant of their responsibilities. You put this all together and feed efficiency has become much better. The best example that I give overall is in sow productivity. Back in 1975 a typical sow would produce somewhere around 700 kilograms of pig per year. That’s per offspring in a year.
In 2014 that same sow would produce almost two thousand kilograms, so a major increase. The significance of that is that if we wanted to produce the same number of market hogs today using sow productivity from 1975 we would need another nine million sows in our herd, we only have six million now, and just the cost of feeding those extra sows would increase the cost of production by 23 dollars per market hog.
Dr. Patience notes there isn’t 23 dollars of profit in producing a market hog so that gives you some idea of the fundamental importance the sector has placed on improving efficiency and therefore maintaining survival.
