Feedlot Lamb Performance and Profitability by Genotype, 63-Day Trial

Thirty lambs of three genotypes were evaluated over 63 days in a feedlot trial. The research by Luciana Porangaba da Rocha compared Dorper and Santa Inês crossbreeds against undefined breeds for weight gain and gross profit margin. Crossbred lambs of Dorper and Santa Inês showed better final body weight and similar biological and economic performance.

Use Cases

• Predicting final body weight based on lamb genotype and feedlot duration
• Comparing feed conversion efficiency between Dorper, Santa Inês, and undefined breed crossbreeds
• Estimating gross profit margin for different lamb genotypes in confinement systems
• Analyzing the relationship between crude protein intake and total weight gain in feedlot lambs

Strengths

• Specific trial details: 30 lambs, 63-day feedlot period, and baseline average weight of 19.31 kg
• Explicit comparison of three distinct lamb genotypes (Dorper x undefined, Santa Inês x undefined, undefined breed)
• Measured economic outcome (gross profit margin) alongside biological performance metrics

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
• Data may reflect geographic bias inherent to paperswithcode, focusing on the semiarid Northeast
