Beef calf production: Consumption and cost-effectiveness – A Mini-Review

Abstract

The objective of this study was to analyze different forms of supplementation for beef calves, considering the relationship between consumption and cost-benefit, aiming at weaning performance. High concentrate levels may reduce forage consumption, which is undesirable as supplementation should increase the efficiency of forage and milk use. The ideal amount of concentrate is 0.5% of the calves' body mass, without changing feed and milk consumption. The supplement must contain between 8% and 30% protein to avoid metabolic disorders and ensure good performance. Adding 10% salt to the concentrate increases economic viability, even with lower consumption, resulting in greater gains and profitability. Adequate supplementation guarantees greater mass at weaning and better daily gain, as long as nutritional management is balanced and economically viable.
