Abstract The objective of this study was to evaluate the association of pseudostem hay of banana trees of different roughages in the diet of F1 Holstein/Zebu cows on their nutrient intake and digestibility, nitrogen balance, microbial synthesis, ingestive behavior, and milk production. The experiment was distributed in two simultaneous 4 × 4 Latin squares. The treatments were as follows: diet 1—sorghum silage as exclusive dietary roughage; diet 2—sorghum silage (70%) associated with 30% pseudostem hay of banana trees (dry matter basis); diet 3—70% elephant grass with 30% pseudostem hay of banana trees (dry matter basis); and diet 4— 70% sugarcane with 30% banana pseudostem hay (dry matter basis). The roughage/concentrate ratio was 75:25. The animals fed with sorghum silage presented 14.45% higher intake (p = 0.01) to that of animals fed hay and elephant grass. The diets containing silage and silage with hay showed digestibility of neutral detergent fiber corrected for ash and protein that was 57.75% higher (p < 0.01) than that of other diets. Cows fed elephant grass spent more time intake (p = 0.01). Diets did not influence milk yield (p = 0.47), and the milk yield corrected for 3.5 fat (p = 0.22), final weight (p = 0.06), and intake efficiency (p = 0.57), presenting a mean of 14.16 kg/day, 15.94 kg/day, 590 kg, and 0.9 kg of milk/kg of ingested dry matter, respectively. The utilization of pseudostem hay associated with other roughage can be an alternative to milk yield in F1 Holstein/Zebu cows. Keywords Byproducts . Elephant grass . Milk production .

Introduction In the last three decades, there has been a great increase in banana crop production in Brazil due to adaptation in some regions and rapid return on invested capital (Diniz et al. 2014). In 2013, Brazil was the fourth largest producer of bananas in the world, producing 6.892.622 t (FAO 2016). With the growth of banana production, it also increases the production of residues from this crop, such as pseudostem, leaves, husks, stink, and heart. These can be used as organic matter in the
