Abstract

Protein sources are essential components of poultry diets, with Soybean meal (SBM) being the most widely used due to its high protein content and balanced amino acid profile. However, its increasing cost and limited availability have encouraged the search for alternative plant protein sources such as sweet lupine (lupinus angustifolius). Dietary protein plays a crucial role in growth, performance, and blood profile parameters in determining the overall effectiveness of dietary treatments. Hematological and biochemical indices are valuable indicators of the physiological condition, metabolic activity, and health status of poultry. The current study aimed to evaluate the effect of replacing SBM with sweet vitabor lupine (SVL) in Sasso T₄₄ dual-purpose chicken diets on growth performance and blood hematological and biochemical indices. A total of 180 chickens with five dietary treatments (Ts) were used. SBM was replaced by SVL at 0 (T1, control), 15 (T2), 25 (T3), 30 (T4), and 50 (T5). Each treatment had three replicates of 12 chickens and was fed for 90 days. Blood hematological parameters and biochemical indices of experimental chickens were measured on day 90. Results revealed that increasing SVL inclusion significantly affected the hematological, biochemical, and growth performance of experimental chickens. Live weight, carcass weight, and dressing percentage were significantly improved in T5 chickens compared to T1, T2, T3, and T4, indicating enhanced production performance with SVL inclusion. However, feed conversion efficiency remained statistically unchanged across treatments. Compared with the control diet (T1), chickens fed the highest SVL level (T5) had higher red blood cell counts and hemoglobin concentrations; however, despite the hematocrit value (36.18) remaining within the normal standard reference range (25â��45), it was significantly lower. Diets T4 and T5 also resulted in higher total protein and lower uric acid and creatinine levels relative to the control, while glucose and triglycerides were unaffected; however, cholesterol was higher in T5. Overall, the results of the present study suggest that SVL may serve as a potential alternative plant protein source to partially replace SBM in diets of Sasso T₄₄ dual-purpose chickens, with no observable negative effect on growth performance and almost all hematological and biochemical parameters. © The Author(s) 2026.
