Özet

This study examined the laying performance (body weight change, egg-laying rate, feedintake, egg weight, and FCR) of Lohmann Brown hens (20-week-old) housed with a deep-litter system and fed fermented protein supplementary feed (FPS; 630 g CP/ kg DM,Integro®) as a protein source. The study lasted for 12 weeks. The hens were randomlyallocated into four groups, each with four replicates of 25 hens. The control group was fed aconventional diet (C), while the other groups were fed a conventional diet with 20 (FPS20),30 (FPS30), and 40 (FPS40) g/kg FPS. A corn–soybean meal-based conventional diet in mashform and water were provided ad libitum throughout the experimental period for alltreatments. The highest feed intake value was observed in the FPS40 group, while the lowestwas observed in the FPS20 and FPS30 groups. The C and FPS20 hens produced eggs with ahigher weight than those produced by the FPS40 group. The FPS20 and FPS30 hens exhibiteda superior feed conversion ratio (FCR) in comparison to the C and FPS40 hens. Thetreatments had no effect on the final body weight or egg-laying rate. The study providescompelling evidence that the addition of 30 g/kg FPS to the hen diet is beneficial withoutnegatively impacting laying performance

The control group was fed a conventional diet (C), while the other groups were fed a conventional diet with 20 (FPS20), 30 (FPS30), and 40 (FPS40) g/kg FPS. The highest feed intake value was obtained from FPS40 hens while the lowest were in the FPS20 and FPS30 hens. The C and FPS20 hens produced heavier eggs than the FPS40 group. The FPS20 and FPS30 hens had a better FCR than the C and FPS40 hens. The treatments did not have any effects on final body weight or egg-laying rate. Overall, the study provides clear evidence for the benefits of adding 30 g/kg FPS to the hen diet without negatively impacting laying performance.
