| Popis: | Background: The use of pequi by-product as animal feed is an appealing alternative to reduce overall production costs. However, little is known regarding its effects on animal performance as well as the ideal inclusion level in the diet. Objective: To evaluate performance, intake, and digestibility of confined lambs receiving diets containing different levels of pequi by- product as a partial substitute for corn silage. Methods: The experiment was conducted in Curvelo, Brazil, using twenty-five crossbred Santa Inês male lambs (17.83 ± 1.73 kg) aged six months for 92 days. Increasing levels of pequi by-product (0, 6, 12, 18, and 24%) replacing corn silage were evaluated in a completely randomized design. Analysis of variance and regression were performed, with 5% significance level. Results: Inclusion of pequi by-product did not influence (p>0.05) average daily gain, total weight gain, or feed conversion ratio. No effect (p>0.05) was also observed on intake of dry matter, organic matter, ether extract, crude protein, neutral detergent fiber, total carbohydrates, and total digestible nutrients. However, a linear decrease was observed (p0,05) en la ganancia de peso diaria, ganancia de peso total, ni conversión alimenticia. No se observó efecto (p>0,05) en la ingesta de materia seca, materia orgánica, extracto etéreo, proteína bruta, fibra detergente neutra, carbohidratos totales y nutrientes digestibles totales. Sin embargo, se observó una reducción lineal (p0,05) o ganho de peso médio diário, o ganho de peso total e a conversão alimentar. Também não foi observado efeito (p>0,05) no consumo de matéria seca, matéria orgânica, extrato etéreo, proteína bruta, fibra em detergente neutro, carboidratos totais e nutrientes digestíveis totais. Entretanto, foi observada redução linear (p |
