The Effects Of Substituting True Protein With Non-Protein Nitrogen In Holstein Dairy Heifers Precision-Fed Different Forage To Concentrate Ratios, Noe Alberto Gomez
The Effects Of Substituting True Protein With Non-Protein Nitrogen In Holstein Dairy Heifers Precision-Fed Different Forage To Concentrate Ratios, Noe Alberto Gomez
Animal Science
Understanding the efficiency and digestibility of dietary nutrients in dairy heifers is essential for minimizing costs and environmental impacts of the dairy industry. The objective of this study was to interpret the effects of manipulating rumen-degradable protein (RDP) in a precision feeding system. Eight Holstein ruminally cannulated heifers (14.6 ± 0.1 mo of age, and 386 ± 9.1 kg of weight) were randomly assigned to 2 forage levels: HC (25% forage) and LC (75% forage) and to a degradable protein sequence [0% degradable protein from urea U, 100% casein C (no urea treatment U0); 33% U, 67% C …
