However, at 7 and 14 days, the composition of the cecal library appeared to be a subset of the ileal library. Ileal and cecal sequences were analyzed to calculate library coverage. The mammalian final host, becomes infected by ingesting metacercariae on the aquatic plants. Our studies not only confirmed this microbial succession in young chicks, but it also indicated that the microbial community structure was fairly stable during the period of rapid skeletal growth 14 to 28 days of age and then had a significant change during the period of significant weight gain at the end of the grow-out 49 days. The microfloras of our birds, which were fed a vegetarian diet lacking growth-promoting antibiotics and antiparasitic agents, contained more clostridia and Bacillus-Lactobacillus-Streptococcus than those reported by Zhu et al. Chicks were fed ad libitum a commercial corn-soy diet that did not contain animal protein, growth-promoting antibiotics, or coccidiostats. This article has been cited by other articles in PMC.
Similarly, the ileum had a stable bacterial community structure for birds at 7 to 21 days of age and between 21 to 28 days of age, but there was a very unique community structure at 3 and 49 days of age.
