Amonificación de residuos de cosecha de gramíneas del trópico para la alimentación de bovinos en la etapa de crecimiento

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.
