References on Avian Biology, Nutrient Allocation, and the Foods Produced by Poultry

By Kermit Blackwood

 

The following sources support Articles One through Five. They address feather growth, molt, medullary bone, heat, nutrient retention, ammonia, parental nutrition, pigment allocation, and the deliberate enrichment of eggs and poultry foods.

Dietary conditioning and OptimizerRation™ represent the framework, management system, and nutritional tool developed through Kermit Blackwood’s applied research and husbandry work.
