Research
was conducted at Merrick's Research Farm in Union Center, WI to compare the
performance of calves fed a 20% protein, 20% fat all milk replacer under
conventional settings to that of calves fed a 25% protein, 15% fat all milk
replacer under an intensive growth setting.
Protocol:
Length of trial:
|
8 weeks |
Number of calves:
|
80 Holstein bull-calves (40 per
treatment) |
Treatments:
|
Conventional: Calves were offered 1lb. of milk
replacer powder reconstituted to 12% dry matter daily
Intensive: Calves were offered 1.5lb. of milk replacer powder reconstituted to
18% dry matter daily
|
Housing:
|
Individual hutches |
Starter:
|
All calves were offered
free-choice starter beginning at day 7 |
Weaning: :
|
Calves were weaned at a minimum
of 42d of age or when they had eaten a minimum of 1 lb. of calf starter per day
for 3 consecutive days. |
Trial Results and Conclusions:
-
Calves on the intensive diet gained on
average 23 lbs. more than calves on the conventional diet.
-
Total feed intake for the trial was greater
for calves fed the intensive diet.
-
Feed efficiencies for calves fed the
intensive diet were greater than for calves fed the conventional diet.
-
There were no differences in the average
number of scour days or days treated.
