dc.description | The present research work deals with the ammonification of harvest residues of tropical grasses for feeding cattle in the growth stage. Ammonification is a process that improves the nutritional quality of crop residues. It is an economical and accessible process for livestock producers. When the use of ammonification is carried out on crop residues, their nutritional value is improved, for example, with respect to rice harvest residue ammonified using 3% urea, there was an increase in crude protein from 5.0% to 12. 4%, in corn crop residues using 3% urea there was an increase in crude protein from 10.4% to 14.7%, in the case of sugarcane bagasse when 5% urea was used there was an increase of crude protein from 4.76% to 9.55% with the ammonification process. By improving the nutritional quality of crop residues, they can be implemented in bovine feeding. The conclusions determine that making use of ammonified crop residues turns out to be a profitable strategy, since when dual-purpose cattle are fed with crop residues of ammonified grasses there is an increase in milk production. In the case of milk-producing cows fed with crop residues of ammonified rice using 4% urea, they obtained an increase in milk production of 5 kg per animal per day, in the case of corn crop ammonified at 6%. They obtained a milk production of 0.6 liters/cows/day, and when they were fed with 30% ammonified sugar cane bagasse plus 70% sorghum silage they obtained a milk production of 8.12 bottles per day, it has been proven that through this process it is beneficial for cattle. | es_ES |

dc.description.abstract | El presente trabajo investigativo trata sobre la amonificación de residuos de cosecha de gramíneas del trópico para la alimentación de bovinos en etapa de crecimiento. La amonificación es un proceso que permite mejorar la calidad nutricional de los residuos de cosecha. Es un proceso económico y accesible para los productores ganaderos. Cuando se lleva a cabo el uso de la amonificación en los residuos de cosecha se mejora su valor nutritivo, por ejemplo respecto al residuo de cosecha de arroz amonificado utilizando 3% de urea hubo un incremento de proteína bruta de 5,0 % a 12,4 %, en los residuos de cosecha de maíz utilizando urea al 3 % hubo un incremento de proteína bruta de 10,4% a 14,7%, en el caso del bagazo de caña de azúcar cuando utilizaron 5 % de urea hubo un incremento de proteína cruda de 4,76% a 9,55% con el proceso de amonificación. Al mejorar la calidad nutricional de los residuos de cosecha se pueden implementar en la alimentación de bovinos. Las conclusiones determinan que al hacer uso de los residuos de cosecha amonificados resulta ser una estrategia rentable, ya que cuando se alimenta a los bovinos de doble propósito con residuos de cosecha de gramíneas amonificados existe un incremento en la producción de leche. En el caso de las vacas productoras de leche alimentadas con residuos de cosecha de arroz amonificado utilizando 4% de urea obtuvieron un incremento en la producción de leche de 5 kg por animal al día, en el caso de la panca de maíz amonificada al 6% obtuvieron una producción de leche de 0,6 lt/vacas/día, y cuando se alimentaron con 30% bagazo de caña de azúcar amonificada más silo de sorgo al 70% utilizando 1,5% de urea obtuvieron una producción de leche de 8,12 botellas por día, está demostrado que mediante este proceso si resulta beneficioso para los bovinos. | es_ES |
