Abstract: 

The research aimed to evaluate the effect of replacing sawdust with tobacco bagasse in the broiler pens’ floor mats on the broilers’ productive performance. In the experiment, 450 Ross chicks were randomly distributed at the age of one day within three different treatments according to the type of litter used: T1_TOb tobacco bagasse, T2saw sawdust. , T3_Mix (50% sawdust + 50% tobacco bagasse) with /150/ sauces per treatment, and each treatment included three replicates with /50/ sauces per treatment. The results showed the positive role of tobacco dregs in improving the nutritional activity of chicks, as the treatment T1_Tob recorded a significant increase in feed consumption (4480.2) grams compared to the two treatments T2_Saw (4279.7) grams and T3_Mix (4382.3) grams, and the treatment T1Tob recorded a significant increase in the feed conversion factor T1_Tob (1.72), followed by the T3_Mix treatment (1.59), then the T2_saw treatment (1.50), and the treatment T1_Tob gave the best results for the productive index of birds of all treatments (331.01) at the age of 35-28 and (374.92) at the age of 42-35, and the treatment T1_Tob recorded a significant decrease in the percentage of Mortality was 2%), followed by treatment T3_Mix (3.33%), then treatment T2_Saw (4%).
