Reduction of Dietary Fibre Near Market Weight Improves Carcass Yield
Dr. Joel DeRouchey - Kansas State University

Farmscape for January 15, 2019

An extension Swine Specialist with Kansas State University says pork producers have recognized the value of reducing the amount of fibre in the diet as the pig approaches market weight.
"Feeding Programs to Optimize Feed Efficiency and Carcass Quality of Grow Finish Pigs" was among the topics discussed last week as part of the 2019 Banff Pork Seminar.
Dr. Joel DeRouchey, an Extension Swine Specialist with Kansas State University, notes feed represents 80 percent of the cost of producing pork so it's important to get the equation right.

Clip-Dr. Joel DeRouchey-Kansas State University:
When we talk about carcass quality we can break that into a couple of different areas.
Some will refer to carcass quality as the meat quality, the carcass traits of leanness, marbling, color, those types of aspects.
We can also look at carcass quality really defined as how much carcass is there relative to weight such as the yield.
Often times we find that our higher fibre ingredients, if we feed those at a higher level to the end and to the point we market the pigs, they inherently are going to have a lower yield because that extra fibre creates a larger gut fill, a heavier waste stream in the intestines and that weight is simply lost once those animals are harvested .
Again, it's very typical that many producers will put in some sort of withdraw strategy of high fibre ingredients during the last two to three weeks and I would say that practice has really been adopted over the last five years,
That has not been a historical way of formulating diets but, as we've come with new information and discovered the impact, we find that very routinely.

Dr. DeRouchey says it's still about dollars and cents and often times we're still fixed with what we have available.
He says the reality is, if you're in a corn growing area, corn is going to be your major cereal grain where as if you're more in the western provinces you're going to have wheat and barley as your major opportunity.
