Abstract
Mango and mustard seeds have been consumed worldwide as food and medicine since ancient times. An experiment was conducted on 120 white leghorn layers (18 weeks old) to discern the effect of feeding mustard seed powder and mango leaf powder on production performance, egg quality and haemato-biochemical parameters. 120 birds were divided randomly into 4 groups. Each group consisted of 30 birds and each group was further subdivided into 3 replicates of 10 birds each. A 90 days feeding trial was conducted in a completely randomised block design. The experimental birds were randomly divided into four treatment group’s viz T1(control): basal diet; T2: basal diet supplemented with 0.5% mango leaf powder; T3: Basal diet supplemented with 0.5% mustard seed powder, T4: Basal diet supplemented with combination of mango leaf powder (0.25%) + mustard seed powder (0.25%). Production performance was conducted in three different phases viz., Phase I (20-24 weeks), Phase II (25-28 weeks) Phase III (29-32 weeks). At the end of feeding trial, a metabolic trial was conducted to know the nutrient utilization. Highly significant difference (P≤0.01) was observed in FCR (Phase I and overall), overall average body weight, dry matter utilization, egg weight, egg NFE, egg glucosinolate, serum glucose, total cholesterol, triglyceride, LDL and VLDL while significant difference (P≤0.05) was observed in feed crude protein, ether extract, NFE, glucosinolate, egg production(all phases), feed intake(all phases), FCR (Phase II and Phase III), crude protein utilization and organic matter utilization, egg shape index, egg shell thickness, albumen weight, egg ether extract, egg Ca and P, egg triglyceride, serum SGOT and serum SOD. It may be concluded that mango leaf powder and/or mustard seed powder does not improve production performance in commercial layers although mango leaf powder is beneficial for improving the serum biochemical parameters.
