However, coccidiostats are also antibiotics, and evidence of resistance in both coccidia and bacteria may develop and reduce antibacterial activity in humans. This has led to a search for natural coccidiostats, such as green tea.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Objectives<\/jats:title>\n                    <jats:p>To study the effects of supplementing broilers with various levels and types of green tea, in comparison to use of a conventional coccidiostat or a control, unsupplemented diet.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>A total of 360 male, day\u2010old Ross 308 broilers (days 1\u201342) were used to evaluate the gut morphology and performance when challenged with coccidiosis and fed varying dietary levels of green tea powder or extract. Treatments were Negative control (NC, unsupplemented control diet); positive control (PC, control diet + commercial coccidiostat); control diets with 0.2, 0.3 or 0.4 g\/kg green tea extract (GTE 0.2, 0.3 and 0.4); and control diets with 1, 2 or 3 g\/kg green tea powder (GTP 1, 2 and 3).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Compared with NC, PC and all green tea treatments, but particularly GTE0.4, increased feed intake and growth rate, with the best feed conversion ratio at GTE0.4. As a proportion of carcase weight, higher inclusion rates increased intestine weight and decreased abdominal fat. The duodenum, jejunum and ileum of birds fed green tea, and particularly GTE0.4, had longer, wider villi, and shallower crypts.
