Maternal treatment effect on egg production and ADG during the broiler breeder phase (1). LPS was inoculated at the beginning of wk 33 (arrow) and simultaneously the treatment with β-glucan was also started at this timepoint. (A) Egg production in wk 34 for broiler breeder hens that were inoculated with LPS showed lower egg production (∼8% compared to control). (B) ADG in wk 34 to 35 showed that growth was significantly higher in the LPS treatment group compared to the control. (A and B) N = 6 pens per treatment with 27 hens per pen. Data is represented as lsmeans. Effects are represented as superscripts and were considered to be significant when P ≤ 0.05. Abbreviations: ADG, average daily gain; lipopolysaccharides.
