In Winter ’09 – some of our case study In Winter ’09 – some of our case study farms worked an extra 12 to 15 farms worked an extra 12 to 15 hrs/day during birthing as compared hrs/day during birthing as compared to as low as 2 hrs/day for other farms to as low as 2 hrs/day for other farms with similar herd sizes, productivity with similar herd sizes, productivity and mortality rates and mortality rates

Neonatal mortality is Neonatal mortality is greatly affected by:greatly affected by:

Grafting Protocol Overview 1. Must be very aware of livestock needs and opportunities.

2. Using techniques that concentrate birth period (i.e. ram/buck effect, concentrated male to female ratio) will allow more matching opportunities.

3. Assess these variables in making match• Milk supply• Milk requirement• Maternal bond• Newborn suckling drive

Grafting Protocol

• Maintain graftee “natural” suckling drive by stomach tube feeding (24-48 h limit)

• Maternal bond develops quickly (less than 5 min) but this is highly variable-need to assess each situation

• Assess milk supply and use this info to determine which newborns to remove and which graftees to bring.

• Possible to swap or mix entire litters if done before bonding is set.

• Possible to graft in pasture birth.

f

Techniques to facilitate bonding

1.Simulate birth process with hand in

birth canal (use plastic ob sleeve). 2.Place fetal fluids from maternal litter

on graftee.3.When grafting into established litters

or refining matches, place newborn feces from maternal litter on graftee.

4.Use head gate or halter to restrain mother if bonding is already established. Grafting success will be apparent within 48 h.

Warming box:

•Forced air heating (inexpensive electric heater)

•Compartments

•Wire mesh flooring
