A total of 300, day-of-hatch, female broiler chickens were weighed and randomly assigned into the following dietary treatment conditions: 1) 1 % starter, 2) 1 % grower, 3) 1 % starter-grower-finisher, 4) 5% starter, 5) 5% grower, 6) 5% starter-grower-finisher, 7) 10% starter, 8) 10% grower and 9) 10% starter-grower-finisher. Each treatment was replicated 3 times with 10 chickens per replicate. Half the broilers in each treatment were challenged with a mixture of three pathogenic Eimeria spp.( E. acervelina, E. maxima and E. tenella) via oral gavage at 4 weeks of age. The body weights of broilers given FMG at the 1% inclusion level were significantly lower compared to broilers in the 5% and 10% starter phase. Eimeria counts for challenged broilers in the 5% grower phase were significantly higher than that of broilers given the 1% and 10% inclusion. Elevations in IgA and IgG levels were observed in the grower phase at the 1% level as well as the starter-grower-finisher phase at the 10% level. | Keywords/Search Tags: | Phase, Level, 10%, Grower, Broiler, Starter | | Related items |
