EFFECT OF SUPPLEMENTATION OF KADIPATTA AND NEEM LEAF POWDER ON NUTRITIONAL QUALITY OF EGG
Author: Khushboo Rishishwar, Anshu Rahal
Abstract:Nowadays herbs are used in poultry diet as feed additive. In present trial the effect of supplementing tree leaves on egg quality was studied. One hundred twenty white leghorn layers were selected, divided randomly and subjected to six treatments. Eggs collected were analyzed for nutrient composition and quality. Egg protein content increased and significant differences were found in cholesterol and low density lipoprotein. Neem and/or Kadipatta leaves @0.5% can be used in poultry diet.
Keywords: Neem leaf powder, Medicinal herbs, Kadipatta leaf powder
INTRODUCTION Medicinal herbs have long been used in poultry diet as feed additive replacing antibiotics which leave their residue in animal products. Neem and Kadipatta are used worldwide due to their notable pharmacological activities like hepatoprotective, cholesterol reducing property, anti-microbial, antibacterial, antiulcer and phagocytic activity.The present investigation was done to assess the effect of supplementation of leaves of neem and Kadipatta on egg quality. One hundred and twenty white leghorn layers(22 weeks) were selected ,divided randomly and fed six treatment diets as follows; viz., T1 , Control; T2 , 0.5% kadipatta leaf powder; T3 , 0.5% neem leaf powder; T4 , 0.5% kadipatta and neem leaf powder (50:50); T5 , 0.5%kadipatta and neem leaf powder ( 25:75 ); T6 , 0.5% kadipatta and neem leaf powder (75:25 ratio) for 12 weeks. Production performance was studied in 3 different phases viz., Phase I (22-25 weeks) and phase II (26-29 weeks) and phase III during post treatment period (30-33 weeks). At the end of feeding trial a metabolic trial was conducted to know the nutrient utilization. For the egg composition and quality study three eggs were collected randomly for three days per replicate.
The data obtained were analysed using Analysis of Variance (ANOVA) and the critical difference (CD) was calculated to determine any significant difference among the treatment means (Snedecor and Cochran, 19941 ) by using STPR3 analysis software. The average egg production, feed intake and feed conversion ratio in various treatments during phase I and overall period were non- significantly different from each other while highly significant difference (P≤0.01) was found in phase II. In overall period (22-29 weeks) although the groups were non significantly different from each other, highest egg production was noted in group T4 in which neem and kadipatta leaf powder was supplemented in ratio 50:50 followed by T5 and T3 . Supplementation of neem and kadipatta leaf powder in 50:50 ratio caused increase in egg production which may be possibly due to presence of macrominerals i.e. potassium, magnesium, calcium, phosphorus and microminerals such as iron, copper, manganese and zinc in the leaves of neem and kadipatta(Atangwho,20092 and Bhowmik et al. ,20083 ).
Supplementation of kadipatta and neem leaf powder affected feed nutrient utilization. Increased utilization of dry matter, crude protein, ether extract and crude fibre was noted on addition of kadipatta to neem leaf powder in different proportion to the basal diet of layer. The values of T4 group differed significantly from the control group in crude protein and ether extract utilization. In egg quality parameters egg weight was significantly (P≤0.05) increased in group T4, T5 and T6 respectively, in which neem and kadipatta leaf powder were supplemented in different combination.
The shape index, yolk weight, shell thickness and shell weight were found to be unaffected by supplementation of neem and kadipatta leaf powder during whole experimental period. Table 1 depicts the nutritional composition of egg of different supplemented groups. The dry matter content of egg of experimental layers showed non-significant differences among the treatment group. Crude protein was observed to be significantly (P≤0.05) increased in the neem leaf powder supplemented group. Ether extract was highly significantly (P≤0.01) increased in the supplemented group.
Ash content showed non-significant differences among the treatment groups. Egg cholesterol and Low Density Lipoprotein differed significantly (P≤0.05) among the different treatment groups while non-significant differences (P≥0.05) were noted in High Density Lipoprotein and triglycerides value. Das et al. (2011)4 reported that kadipatta leaf powder at low concentration 0.2% was effective inhibitor of primary and secondary oxidation products in raw ground and cooked meat patties and has potential as a natural antioxidant in cooked and raw meat system.
CONCLUSIONS It can be concluded that Neem and Kadipatta leaves @ 0.5% can be incorporated in layer diet to improve egg quality.
