Neonatal Care

Background:

The Apgar score is a standard for assessing newborn viability in humans and animals.
Adapting this score for lambs can improve neonatal care and survival rates.

Purpose of the Study:

To modify the Apgar scoring system for lambs.
To evaluate the correlation between Apgar scores and factors like litter size, birth order, time-to-stand, and time-to-suckle.

Main Methods:

Seventy-five Polypay lambs were assessed using a modified Apgar system measuring appearance, pulse, grimace, attitude, and respiration.
Pulse and oxygen saturation were measured using a pulse oximeter.
Time-to-stand and time-to-suckle were recorded and compared with Apgar scores at birth (T0), 15 minutes (T15), and 60 minutes (T60).

Main Results:

Apgar scores showed no significant differences based on litter size or birth order.
No significant correlations were found between Apgar scores and the time lambs took to stand.
A moderate positive correlation (R² = 0.467) was observed between lamb attitude at T0 and time-to-suckle, indicating potential challenges in colostrum intake.

Conclusions:

The modified Apgar score is a viable tool for assessing lamb viability.
Lamb attitude at birth is a key indicator for timely colostrum ingestion.
Producers can utilize Apgar scoring to identify lambs needing immediate assistance, potentially preventing serious complications.
