A

Rapid fetal growth
Changing diet
Initiation of lactation (sudden ca demand, hormonal)

3
Q

Transition management keys

A
Minimize DMI depression prepartum 
Minimize Dystocia 
Minimize hypocalcemia 
Minimize endometritis/metritis
Maximize DMI postpartum
4
Q

Feed intake

A

Drop 30% before calving

Energy requirement increases 20-30%

5
Q

Prepartum DMI affects

A

Immune function, risk for ketosis, start up milk, postpartum feed intake

6
Q

How to min drop in feed intake

A

Remove obstacles/stress (overcrowding, balanced TMR, feed to 3-5% refusals, group similar)

A

1- unsteady, tremors, cool extremities, <.5

3- lateral recumbent, bloat and death

8

A

Dry cow- 10-12g/d
At calving must bring 30g/d into Ca pool
Must absorb more from intestine or mobilize bone

9

A

Traditional- restrict ca intake, activate PTH

DCAD- balance anions and cations, increase tissue respose

10
