Article Synopsis
- * Key factors affecting nitrogen excretion included dry matter intake, nitrogen intake, dietary composition, and animal growth metrics; models were evaluated using statistical measures like root mean square error (RMSE) and concordance correlation coefficient (CCC).
- * While fecal N excretion models showed better accuracy than those for urinary excretion, different predictors led to varying performances, with nitrogen intake generally performing better for urine, indicating the complexity of predicting N excretion based on diet and management.
On-farm methane (CH) emissions need to be estimated accurately so that the mitigation effect of recommended practices can be accounted for. In the present study prediction equations for enteric CH have been developed in lieu of expensive animal measurement approaches. Our objectives were to: (1) compile a dataset from individual beef cattle data for the Latin America and Caribbean (LAC) region; (2) determine main predictors of CH emission variables; (3) develop and cross-validate prediction models according to dietary forage content (DFC); and (4) compare the predictive ability of these newly-developed models with extant equations reported in literature, including those currently used for CH inventories in LAC countries.
