What is Long-term Effects of Dietary Calcium and Phosphorus Level, and Feed Form During Rearing on Egg Production, Eggshell Quality, and Bone Traits in Brown Laying Hens from 30 to 89 Wk of Age about?
The effects of feeding strategies during rearing (0–16 wk) of brown laying hens on mid and end laying performance (30–89 wk) were studied. The rearing feeding strategies followed a 3 × 2 factorial arrangement with feed form; mash with inclusion of 3% finely ground wheat straw (MWS), crumbles with inclusion of 3% finely ground wheat straw (CWS), and crumbles with inclusion of 3% unground oat hulls as fiber sources (COH) at 2 dietary Ca and P levels (high or low Ca–P). Feed conversion ratio improved with COH and MWS compared with CWS from 30 to 59 wk. Rate of lay and egg mass production showed a feed form × Ca–P interaction from 60 to 89 wk. Low Ca–P led to a higher egg production, but only when COH and MWS were fed. BW at 89 wk was higher with CWS compared to COH and MWS. BW uniformity was better with COH compared to MWS at 51 wk and both CWS and MWS at 67 wk. Tibia characteristics were not clearly affected by treatment, although there was a feed form × Ca–P interaction on compression at 89 wk, where compression was lower with MWS and low vs. high Ca–P. Low Ca–P during rearing led to higher eggshell thickness, compared to high Ca–P at 45 wk of age, but breaking strength was lower wi
