“Days” is duration, with captive day 0 being their admittance to the PDRC (Athens, GA), for which nestlings consumed a specific diet phase. All nestlings received the same diet (natural) until they were in captivity for 113 days, after which the designated anthropogenic pen (n = 10) began receiving white bread and reduced seafood content. The day the new diet was given is considered to be experimental day 0. Dry matter is defined as the nonmoisture portion of a feed ingredient or diet. The sum of moisture and dry matter content of a feed on a percent of total will always equal 100. Dry matter contains the essential nutrients within a given feed ingredient or forage.
