    EFFECT OF CEREMONIAL FLORAL WASTES ON PALATABILITY, ANTIOXIDANT STATUS AND EGG QUALITY TRAITS IN COMMERCIAL LAYERS
    (KARNATAKA VETERINARY, ANIMAL AND FISHERIES SCIENCES UNIVERSITY, BIDAR-585401, 2022) ARUN, F.M.; T. THIRUMALESH
    The study was conducted to determine the effect of ceremonial floral wastes on palatability, antioxidant status and egg quality traits in commercial layers. Three hundred and twenty-four commercial layer birds (30th weeks of age) were divided into nine treatments with four replications in each treatment and each replication had nine birds each in CRD. The CFW like marigold floral waste (MFW), rose floral waste (RFW) and chrysanthemum floral waste (CrFW) were incorporated in the commercial layer diet at 7 per cent (T2) and 8 per cent (T3) MFW, 7 per cent (T4), 8 per cent (T5) and 9 per cent (T6) RFW, 1 per cent (T7) , 2 per cent (T8) and 3 per cent (T9) CrFW and comparative to non CFW group (T1-control). The crude protein contents of MFW, RFW and CrFW were 8.55, 10.72 and 11.73 per cent respectively. The layer diets incorporate with CFW by replacing de-oiled rice bran contained 18 per cent CP, 2007 ME kcal/kg diet. The experiment was conducted for a period of 12 weeks containing 30th to 42nd weeks of laying phase. During the experiment feed intake, feed conversion ratio, egg production, egg weight were recorded, egg quality traits were evaluated. The blood samples were collected before and after the experiment to estimate the antioxidant activity in the serum and at the end of the experiment metabolism trial was conducted to know the digestibility of nutrients. The mean feed intake between the treatment groups were significantly higher in T1, T5, T8 and T9 whereas significantly higher (P<0.01) dry matter intake was noticed in T7. The per cent hen day egg production between the treatment was significantly different (P<0.01). The mean feed conversion ratio was better in T2, T3, T4, T7, T8 and T9 when compared to other treatment. The average mean yolk index was similar in T2 and T3 but significantly higher in T4 and lower in T7 and T8. The 180 yolk colour was significantly higher in T3 followed by T2, T4, T7 and T8. The levels of CP in the egg were higher in MFW and RFW fed groups. Almost all the CFW had better antioxidant activity and the benefit-cost ratio was higher in all the CFW supplemented groups than the control group. It can be concluded that beyond 8 per cent MFW and 3 per cent CrFW can be used without any adverse effect in the commercial layer diet, however RFW may be included only with petals but not with calyx and peduncles.
