Abstract
ABSTRACT We assessed the effects of different amounts of water-treated black tea waste (BTW) in the diets of laying hens on performance, egg quality, yolk peroxidation, and blood parameters in this study. The experiment lasted for 12 weeks, during which a total of 108 Lohman layers, of 24 weeks old, were randomly allocated to one of six dietary treatments (18 hens each); each treatment consisted of six replicate cages, each containing three hens. Experimental animals were fed a commercial diet [...]

Malondialdehyde values in the egg yolks obtained from treatment groups fed diets containing BTW at different levels and stored for 14 and 28 days were lower than in those of the control group, but there were no differences at 56 days
Summary
The poultry sector has a significant role in meeting the increasing demand for animal products. Inadequacy of poultry feed resources in both quantity and quality is one problem in this sector. For this reason, nutritionists and feed manufacturers have shifted to alternative, cheap, and readily available raw materials that have not been used previously as raw feedstuffs, to reduce feed costs through studies of the evaluation, processing, and use of new feed raw materials (Scheideler et al, 2005). Many agricultural byproducts have use as animal feeds, including tea waste. Black tea waste is completely unused, is largely wasted, or is burned for energy production, causing massive pollution (Kaya et al, 2014)
