The dietary supplementation of canthaxanthin in combination with 25OHD3 results in reproductive, performance, and progeny quality gains in broiler breeders.

The objective of this study was to evaluate the effects of the dietary supplementation of canthaxanthin and cholecalciferol (25OHD3) to broiler breeders and their progenies on their performance. Eighty 25-wk-old Cobb 500 broiler breeders were distributed according to a completely randomized design in 2 experimental treatments, with 10 replicates of 4 birds each. The treatments consisted of the supplementation or not of a corn-soybean meal diet with canthaxanthin + 25OHD3 to broiler breeders fed from 25 to 62 wk of age.
