Researches on The Responses Of Different Hybrid Layers With Respect To Egg Production and Quality Performances To Forced Molting Programs With and Without Feed Withdrawal
Abstract
This research was carried out to determine the effects of four forced molting programs including three non-feed withdrawal programs (BB: barley based, WB: wheat bran based and OB: oat based) which supplied with alfalfa meal and one feed withdrawal method (FW: control 8 d FW+34 d resting diet) on egg production and egg quality performances of 320 brown (H&N Brown Nick) and 320 white (Hy-Line W-36) hybrid layers at 57 week of age. The experiment lasted totally 46 wk including for a 6 wk molting period followed by a 40 wk post molt production period. According to the results obtained; the genotype had significant (P<0.05) effect on body weight loss, feed consumption, hen day egg production (number, %), cracked egg (%) and heterophil:lymphocyte (H:L) ratio (P<0.01) in molting period. Molting methods had significant (P<0.01) effects on body weight loss, feed consumption, hen-day egg production (number, %), pancreas weight ratio in molting period. In the production period; BB group had lower (P<0.05) hen-day egg production (%) than those of OB and FW groups. Feed efficiency values of WB group were better (P<0.05) than the values of OB and FW groups. Hens molted by FW treatment had lower (P<0.05) albumen height and Haugh units than other treatments. As conclusion, after examining these production and quality criteria, it can be stated that; non feed withdrawal methods, especially OB program can be used alternative to FW program. But, other non-feed with-drawal programs also can be used successfully as molting procedure.
