Resumo: | Background: Inclusion of urea and calcium oxide (CaO) during sugarcane ensilage has been hypothesized to improve dairy cow performance. Objective: To evaluate the use of urea and calcium oxide as additives to preserve sugarcane silage quality and determine whether they improve dairy cow performance and metabolic efficiency. Methods: Four diets were used: sugarcane silage without additive (SS), sugarcane silage with 10 g/kg urea (SU), sugarcane silage with 5 g/kg urea + 5 g/kg CaO (SUC), and sugarcane silage with 10 g/kg CaO (SC). Eight crossbred cows at approximately 100 days of lactation were distributed in two 4x4 Latin squares, and their diets were formulated to reach an average milk production of 15 kg/day. Results: Dry matter, non-fibrous carbohydrates, organic matter, total carbohydrates, and total digestible nutrient intake were the highest (p<0.05) for the cows fed SC. Urinary excretion of nitrogen was higher (p<0.05) for cows fed diets based on SUC than those fed diets with SC. Milk urea nitrogen content was the highest (p<0.05) in animals fed SU diets. Nitrogen balance was positive in all treatments; however, the microbial protein synthesis was low for all diets. Conclusions: The diet with SU showed the highest nitrogen loss through the milk. Among the evaluated silages, those with SC and SUC are recommended to promote a high intake of nutritional components |

Objetivo: Evaluar la urea y el óxido de calcio como aditivos para preservar la calidad del ensilaje de caña de azúcar y determinar si mejoran el rendimento y la eficiencia metabólica de vacas lecheras. Métodos: Cuatro dietas fueron utilizadas: ensilaje de caña de azúcar sin aditivo (SS), ensilaje de caña de azúcar con 10 g/kg de urea (SU), ensilaje de caña de azúcar con 5 g/kg de urea + 5 g/kg de CaO (SUC) y ensilaje de caña de azúcar con 10 g/kg de CaO (SC). Ocho vacas cruzadas fueron evaluadas con una producción media de leche de 15 kg/día y aproximadamente 100 días de lactación, distribuidas en dos cuadrados latinos 4x4. Resultados: El consumo de materia seca, carbohidratos no fibrosos, materia orgánica, carbohidratos totales y nutrientes digestibles totales fue mayor (p<0,05) cuando las vacas fueron alimentadas con dietas conteniendo SC. La excreción de nitrógeno en la orina fue mayor (p<0,05) cuando las vacas fueron alimentadas con dietas basadas en SUC que las alimentadas con dietas SC. El nitrógeno ureico de la leche fue mayor (p<0,05) en animales alimentados con dietas con SU. El balance de nitrógeno fue positivo en todos los tratamientos, sin embargo, la síntesis de proteína microbiana fue baja para todas las dietas. Conclusión: La dieta con SU presentó la mayor pérdida de nitrógeno por medio de la leche. Entre los ensilajes evaluados, aquellos con SC y SUC son recomendados por promover un mayor consumo de componentes nutricionales.Outra AgênciaengUniversidade Federal de Minas GeraisUFMGBrasilICA - INSTITUTO DE CIÊNCIAS AGRÁRIASRevista Colombiana De Ciências PecuáriasBovino de leite -- Alimentação e raçõesBovino de leite -- DesempenhoEnsilagemCana-de-açúcar -- SilagemNutrição AnimalUreia como raçãoPreservation of sugarcane silage with urea and calcium oxide: performance and metabolic efficiency of dairy cowsConservación del ensilaje de caña de azúcar con urea y óxido de calcio: rendimiento y eficiencia metabólica en vacas lecherasPreservação da silagem de cana-de-açúcar com ureia e óxido de cálcio: desempenho e eficiência metabólica de vacas leiteirasinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articlehttps://revistas.udea.edu.co/index.php/rccp/article/view/346613/20805617Susi Cristina dos Santos Guimarães MartinsGleidson Giordano Pinto de CarvalhoAureliano José Vieira PiresLaudí Cunha LeiteDaiane Lago NovaisRonaldo Lopes OliveiraLuis Gabriel Alves CirneBruna Mara Aparecida de Carvalho Mesquitainfo:eu-repo/semantics/openAccessreponame:Repositório Institucional da UFMGinstname:Universidade Federal de Minas Gerais (UFMG)instacron:UFMGLICENSELicense.txtLicense.txttext/plain;

Background: Inclusion of urea and calcium oxide (CaO) during sugarcane ensilage has been hypothesized to improve dairy cow performance. Objective: To evaluate the use of urea and calcium oxide as additives to preserve sugarcane silage quality and determine whether they improve dairy cow performance and metabolic efficiency. Methods: Four diets were used: sugarcane silage without additive (SS), sugarcane silage with 10 g/kg urea (SU), sugarcane silage with 5 g/kg urea + 5 g/kg CaO (SUC), and sugarcane silage with 10 g/kg CaO (SC). Eight crossbred cows at approximately 100 days of lactation were distributed in two 4x4 Latin squares, and their diets were formulated to reach an average milk production of 15 kg/day. Results: Dry matter, non-fibrous carbohydrates, organic matter, total carbohydrates, and total digestible nutrient intake were the highest (p<0.05) for the cows fed SC. Urinary excretion of nitrogen was higher (p<0.05) for cows fed diets based on SUC than those fed diets with SC. Milk urea nitrogen content was the highest (p<0.05) in animals fed SU diets. Nitrogen balance was positive in all treatments; however, the microbial protein synthesis was low for all diets. Conclusions: The diet with SU showed the highest nitrogen loss through the milk. Among the evaluated silages, those with SC and SUC are recommended to promote a high intake of nutritional components |
