Effects of feeding sources of docosahexaenoic and α-linolenic acids to ISA brown and Shaver White breeders and/progeny on body weight of 18-weeks-old pullets. The day-old female pullets from breeders fed CON, DMA, and FFF were divided into 3 (CON, DMA, and FFF), 2 (CON and DMA), and 2 (CON, FFF) posthatch treatments, respectively. The concentration of total n-3 fatty acid and ratio of n-6: n-3 were identical among DMA and FFF diets in both breeder and progeny phases. CON, control; DMA, micro-Algae (Aurantiochytrium limacinum) fermentation product, as a source of docosahexaenoic acid; FFF, co-extruded full-fat flaxseed and pulses mixture (50/50, wt/wt), as a source of α-linolenic acid.
