Ever Bucket Train a Calf?

Many calf feeders use buckets rather than bottles to feed milk to young dairy calves. All of us who have bucket trained calves know that it is a labor-intensive procedure.

This study of 1,235 calves observed the bucket training process.

They found these rates of "Adoption" by the calves:
(percent drinking by themselves)
Day 2 = only 10%
Day 3 = up to 55%
Day 4 = up to 85% drinking by themselves
Day 5 = up to 92%

Now here is the tough part:

Day 6 = 92%
Day 7 = 92%
Day 8 = 92%

This is getting old - these "holdout" calves are breaking my back!

By day 14 this study still had a few calves that were still requiring some kind of assistance. 

Remember, however, by day 8-14 we could easily have calves that have been drinking by themselves  that now have health issues., maybe a little dehydrated. You know, they are alert, lying on their belly but need encouragement to get up to drink and then need me to fuss with them to finish their milk meal.

Maybe it is not realistic to expect 100% of the calves in the first three weeks of age to dive into their milk bucket and lick it clean.

Jim Dickrell's Case Study on Calves

Jim Dickrell, Editor Emeritus at Dairy Herd Management magazine, has this fantastic 2-page case study of a calf enterprise.
It is HERE.

The dairy has about 600 replacement animals. Jim's case study report is divided into these parts:
  • Step One: Nursery Barn
  • Step Two: Weaning Barn
  • Step Three: Grower Barn
It is a quick read full of possible ideas for a successful calf enterprise. 

Enjoy.

Consistency Matters!

"Consistency Matters" is the title of the February issue of the calf management newsletter.

 In brief:
  • Consistency promotes better health and growth.
  • Calf care people are the base for consistent care.
  • Consistent time, especially for feeding.
  • Consistent feeding, especially temperature, volume and solids level.
  • See the Calf Care Consistency Checklist HERE.
