Steers, like these in a feed yard near Aurora, Nebraska, benefit
from being fed DDGS their ration due to: |
• Increased
Palatability
• Rumen By-Pass Protein
• Effective Fiber for Rumen Health
BEEF
FEEDERS
Beef feeders can
use distillers grains at a feeding level of about 20% of their total
dry matter intake. Calves in receiving/starting programs perform well
when distillers grains compose 15 to 20% of their diet. DDGS can be
fed to meet the protein requirement, while WDGS and CDS can be fed to
supply protein and energy requirements. Wet distillers grains has its
greatest value in beef rations when fed at 15 to 25% of diet DM.
Maximum
Inclusion Levels (%DM)
• DDGS 20%
• Wet DGS (30% DM) 25%
• CDS (30% DM) 6.5%
DAIRY
It's important
to remember that distillers grains are also a valuable part of dairy
rations too. The high producing dairy cow can use DDGS at levels up
to 20% of their total DMI. When balancing for dairy with distillers
grains use the NRC model to limit distillers according to lysine, and
feed in combination with other CP sources. Wet distillers grains can
limit gut fill and therefore total DM intake when incorporated with
other wet feeds (e.g. silages, etc.) at a lower percent of DM from distillers
grains. The limit is somewhere between 20 and 30% DMI, however 20% is
the maximum recommended inclusion level.
Maximum
Inclusion Levels (%DM)
• DDGS 20%
• Wet DGS (30% DM) 20%
• CDS (30% DM) 6.5%
POULTRY
While more research
is warranted on the benefits of feeding DDGS to poultry, distillers
grains provide many important nutrients to both chickens and turkey.
Poultry will benefit from the essential amino acid methionine, which
is essential for feathering. DDGS are an excellent source of methionine.
The Phosphorus availability of DDGS is higher than in corn, which is
an economic assistance, as Phosphorus is the third most expensive ingredient
in dairy rations. Higher availability of Phosphorus also contributes
positively to the environment.
Maximum
Inclusion Levels
• Broilers
10%
• Layers 15%
• Turkeys (grow/finish) 10%
SWINE
Research continues
to prove that swine can benefit from having high quality, "new
generation" distillers grains in their diet due to the high energy
(97% the energy value of corn), digestible amino acids, and available
phosphorus. Recent research has shown additional benefits of feeding
DDGS on reducing manure P levels, improvements in litter size weaned
(when sows are fed DDGS at the maximum inclusion rates for 2 reproductive
cycles) and improved gut health of grow-finish pigs when challenged
with ileitis.
Maximum
Inclusion Levels
* Nursery pigs (<15lbs.)
0%
* Nursery pig (>15lbs.)
25%
* Grow-Finish 20%
* Gestating sows
50%
* Lactating sows
20%
