A feeding experiment was carried out in the Department of LPM, C.V.Sc. & A. H., Bhubaneswar and Regional Centre, CARI, Bhubaneswar to study the effect of different levels of protein during laying (20-40 weeks) on egg production, feed consumption and feed conversion ratio in Khaki Campbell ducks. 180 ducks were distributed randomly into three treatment groups with three replicates in each. There were 20 ducks (15 females and 5 males) in each replicate pen and care was also taken to match the average 20th week body weight in all the treatment groups. Between 20-40 weeks of laying stage (experimental period up to 40 weeks), ducks were given isocaloric diets having 16, 18 and 20% protein in treatments T1, T2, T3, respectively. Supplementation of 18% crude protein in the ration during laying period might be sufcient with respect to egg production, feed consumption and feed conversion ratio in Khaki Campbell layer ducks.
