Laying Performance and Egg Quality Traits of Vanaraja Birds as Influenced by Dietary Supplementation of Turmeric Powder

ABSTRACT: The present study was conducted to use turmeric powder as an alternative to antibiotics properties. The current study was designed to determine laying performance, albumin index, yolk index, haugh unit, and yolk cholesterol as influenced by different levels of turmeric powder dietary
supplementation. The experimental birds were randomly divided into four treatment groups designated as T1, T2, T3 and T4 with thirty (30) chicks in each group having five replicates of six (6) birds each. They were
subjected to four dietary levels of turmeric powder containing 0%, 0.5%, 0.75%, and 1.5%, respectively, for a period of 365 days. The overall level of statistical significance was defined as p<0.05. The significance
of the result was evaluated using an analysis of variance (ANOVA) in the computer software WASP. Dietary supplementation with turmeric powder improved laying performance and enhanced egg quality traits. Yolk index and albumen index increased (p<0.05) while yolk cholesterol decreased with the increase in the level of turmeric powder. On the basis of the above findings, supplementation of turmeric powder at 0.75 per cent of feed can be recommended under Nagaland's agro-climatic conditions.
CONCLUSIONS
Turmeric powder supplementation at the rate of 0.75 resulted in better performance in egg production and egg quality traits of Vanaraja birds as compared to the control group. Therefore, on the basis of the above
findings, the use of turmeric powder as a feed additive at the rate of 0.75 in poultry diets may be advocated for better production performance and for producing betterquality eggs.

摘要：本研究旨在探讨姜黄粉作为抗生素替代品的可能性。本研究旨在确定姜黄粉膳食补充剂不同水平对产蛋性能、白蛋白指数、蛋黄指数、哈氏单位以及蛋黄胆固醇的影响。实验用鸡被随机分为四个处理组，分别标记为T1、T2、T3和T4，每组包含30只鸡，每只鸡设有五个重复实验，每个重复实验有六只鸡。这些鸡被分别喂食含有0%、0.5%、0.75%和1.5%姜黄粉的四种不同膳食水平，为期365天。总体统计显著性水平定义为p<0.05。结果的重要性通过WASP计算机软件中的方差分析（ANOVA）进行评估。姜黄粉的膳食补充剂提高了产蛋性能和增强了鸡蛋质量特征。随着姜黄粉水平的增加，蛋黄指数和白蛋白指数增加（p<0.05），而蛋黄胆固醇水平降低。基于上述发现，在纳加兰的农业气候条件下，建议在饲料中添加0.75%的姜黄粉。结论：姜黄粉以0.75%的比率补充，相较于对照组，显著提高了Vanaraja鸡的产蛋性能和鸡蛋质量特征。因此，基于上述研究结果，建议在禽类饲料中添加0.75%的姜黄粉作为饲料添加剂，以促进更好的生产性能和产出更高品质的鸡蛋。
