Growth and Early Laying Performance of Pullet Chickens Fed Sorghum Based Diets Supplemented with Enzymes

A study was carried out to evaluate the effect of replacing maize with sorghum and supplementation enzymes, on growth laying performance chickens. Four hundred fifty 12-weeks old Lohmann Brown pullets were distributed randomly into six dietary treatments three replicates per treatment, each replicate had 25 birds uniform group weights at initial stage study. The included without enzymes (T1) (T2) as two controls respectively, while T3, T4, T5, T6 contained based diets phytase, protease, roxazyme G2G, a combination protease G2G respectively. experiment lasted from 12 32 weeks age during which data collected early egg birds. Data obtained subjected analysis variance, using completely randomized design (CRD). Significant differences among treatment means compared Tukey test. (p<0.05) noted in final weight (g/bird), gain daily total feed intake (g/bird/day), ratio. Final significantly better for T4 (sorghum + protease) other treatments, but similar T1 (control). At stage, no definite trend observed production traits. However, supplemented phytase (T3) highest numerical values for; first (54.28g), number eggs peak lay (24.00), hen house 78.84%, day production, 81.09%. It concluded therefore, that supplementations can be used layers' optimum production. is recommended 0.02% incorporated type chickens performance.
