Study Notes

Parturition and Postpartum Recovery

Parturition is the biological process of giving birth in mammals, marking the end of pregnancy.
It involves three distinct stages:
Stage 1: Dilation and contractions, cervical dilation, and animal preparation.
Stage 2: Fetal expulsion, stronger contractions, and ANIMAL REPRODUCTION.
Stage 3: Placental expulsion, after the birth.

Newborn Care

Not well developed circulatory and respiratory systems:
Initiation of lung respiration due to stimulation of respiratory center in brain by inc. CO2 level.
Thermoregulatory mechanisms:
Not well developed, reduced survival in extremely hot or cold environment.
Absorption and metabolism of nutrients:
Glycogen stored in liver and muscles, used during this adjustment period.
Immune status:
Immune system of neonate not challenged, maternal antibodies absorbed through intestines until 24 hrs after birth.
Colostrum should be fed as early as possible, 6% of birth wt within 6 hrs.

Postpartum Recovery

Factors affecting recovery:
Reproductive readiness, breeding intervals, and postpartum issues.
Common postpartum complications:
Metritis, mastitis, etc.
Management strategies:
Returning to reproductive readiness, treatment, and management.

Other Important Points

Evaluation of pregnant animals and management of post-partum animals.
Pre-weaning management and milk collection.
Identification of animals at LPA with any diseases related to reproductive failure.
