Autor: Edenio Detmann, L. F. Costa e Silva, A C Baião Menezes, F.A. de Sales Silva, S. de C. Valadares Filho, P. Del Bianco Benedeti, T Eder Silva
Publikováno v: Animal, Vol 14, Iss 5, Pp 963-972 (2020)
The accurate estimation of protein requirements for beef cattle is a key factor in increasing livestock profitability and decreasing the environmental impacts of excessive N excretion due to mismatching between assumed requirements and diet formulati

Autor: Terry E Engle, L. F. Costa e Silva, Polyana Pizzi Rotta, Marcos Inácio Marcondes, A.L. Silva, M.M.D. Castro
Publikováno v: Journal of Dairy Science. 102:2973-2984
International committees that have published nutrient requirements for dairy cattle have used data from mineral studies conducted in the 1920s to 1970s, and no study has reported data from animals less than 100 kg; therefore, there is a need to updat
