Abstract
The objective of this study was to evaluate the nutritional impacts of the inclusion of different levels of lentil screenings by-products (LSB) as unconventional protein source on the growth performance, nutrients digestibility, carcass parameters, plasma constituents and economical efficiency of growing rabbits. Sixty New Zealand White (NZW) growing rabbits, 6 weeks age with an average live body weight 617.91 g ±62.35 were randomly assigned to four dietary treatments as follow: the first used as control diet while the other three diets were formulated to replace LSB for soybean meal at levels of 25, 50 and 75%. The results showed that LSB contained 26.60% CP and 12.40% CF on DM basis. LSB was superior in gross energy content than soybean meal. Lentil screenings by-products contain higher concentrations of phytochemicals such as saponnin (26.3 mg/100gDM), phytic acid (610 mg/100g DM), phenolic content (21.01 mg GAE/g DM) and tannins (840 mg catechin equivalent/100 g DM). Rabbits group fed 25% LSB achieved significantly (P
