Abstract:
This work was conducted to identify the main points of contamination of parent (chickens) houses in Khartoum state . A total of 108 samples were collected randomly from the parent houses at age 25 , 35 and 45 weeks as followed 36 sample in 25weeks ,36 sample in35weeks and 36 sample in 45weeks from feeds, water, feathers, nests, litters and coloaca aseptically. The mean (TVCs) and isolation and identification of contamination bacteria were conducted.
The TVCs was high in the sample taken from the coloaca at age 35 and 45weeks (6.25 ±0.08, 6.28±0.06). The contaminated bacteria at different point of contaminated were E. coli and Salmonella spp. In conclusion, the source of contamination can be started from rearing of chick in parent houses, but the reduction of contamination associated sanitary measures.
