Abstract

When birds return to the full feed, new plumage develops and the birds resume egg production at a higher rate with better egg quality. Induced molting extends the productive life of commercial chicken flocks and results in a substantial reduction in the number of chickens needed to produce the nation’s egg supply. The study was conducted to evaluate induced molting in culled white leghorn (Gallus gallus) using a fasting and low-protein diet. The completely randomized design (CRD) with ten replication was used to test the following treatments: T1 (fasting); T2 (medium-cracked maize); T3 (rice bran); T4 (cracked rice); and T5 (control). Results revealed that T1 has the highest test value of crude fat with 48.30 percent. In terms of crude protein, T3 obtained 42.82 percent, while crude fiber T2 had 0.90 percent. On the other hand, T3 and T4 produced the highest protein-content eggs, while T1 produced a total fat level of 48.30%. Each treatment’s egg yield varies in terms of crude protein and crude fats, according to laboratory examination. The lab research also shows that eggs from T3 and T4 are far healthier than eggs from other treatments. Induced hens should be kept for 290 days to achieve maximum laying percentage; keeping them longer will boost feed intake but reduce laying percentage. Keeping hens for a long time increases their risk of developing reproductive anomalies such as uterine prolapse and vent hemorrhages.
