Physiological Study to Broiler Bird Infected with Coccidian Parasite

Abstract

Infection with Eimeria parasites is known as coccidiosisit  can affect all mammals and some types of Birds, some fish, some reptiles, and some amphibians. the infection millions of intestinal cells may become infected when the parasites exit in large numbers for the intestinal cavity to infect other tissues. The result is diarrhea of different types and  including bloody and watery diarrhea. The results of study showed that there are significant differences in the correlation between the increase in the ratio of the blood Fertin protein with the growth hormone, on the contrary, a decrease  level of the  thyroxin (T3) and  (T4) and  research appeares  relationship between the low level of the hormone ,the increase in the growth hormone(GH) and thyroid stemulationhormon (TSH). Coccidiosis affects not effected to  the health of the bird but does not  affect the level of growth hormones  is not related to hormonal deficiency but   lack of absorption of nutrients from the intestine for the damage caused by the parasite in the lining  of the intestine and the villi and thus the growth of the bird.
