Abstract: This study aimed to evaluate intake, digestibility, nitrogen balance, ingestive behavior, and blood parameters of sheep fed with cotton lint levels. Twenty rams weighing 30.2 ± 3.7 kg and aged 12 ± 1.3 months were distributed in a completely randomized design, with four treatments and five repetitions. Diets consisted of 50% roughage and 50% concentrate. The treatments consisted of replacing corn with cotton lint at levels of 0, 70, 140, and 210 g/kg of dry matter (DM) of the diets. The animals’ feeding behavior was determined in the last three days of the experimental period. Data were subjected to regression analysis. Decreased linear effect ( p < 0.05) was observed for the nutritional fraction’s intake. However, neutral detergent fibre (NDF) intake and plasma urea-N were not affected ( p > 0.05) by lint levels. Apparent digestibility of DM, crude protein (CP), ethereal extract (EE), and non-fibrous carbohydrate (NFC) were affected ( p < 0.05), except for total carbohydrate. There was a decreased linear effect ( p < 0.05) for the intake efficiency of DM and NDF in g/h. The nitrogen balance (g/day) and glucose levels (mg/dL) were reduced with the addition of lint in the diet. The addition of cotton lint up to 70 g/kg in DM can be used over a short-term period.
