The greatest loss in ruminant production systems occurs during the neonatal period. The maternal environment (nutrition and physiologic status) influences neonatal mortality and morbidity as it reportedly affects (a) Dystocia, both via incr...
Postnatal Nutrient Repartitioning due to Adaptive Developmental Programming [0.03%]
