Abstract

Cattle genotypes and adoption of new feeding technology are necessary for improving beef cattle production and managing efficiently beef production costs. A study was conducted to determine the effects of cattle genotypes and levels of concentrate supplements on cost effectiveness of feedlot beef production in a Complete Randomized Block Design in 3×4 factorial arrangements with 4 replications. Feeds were urea-treated rice straw (UTRS: 4%, w/w) and concentrates made from decorticated cottonseed cake (66%) and maize bran (34%). The experimental animals were Ankole (A×A: n=16), Ankole × Friesian (A×F: n=16) and Ankole × Sahiwal (A×S: n=16) steers. Proxy indicators used to determine profitability and likelihood of economic viability were Initial and Final values of carcass existing abattoir price (RwF 1800/kg beef); Break-even scenarios using What-if Analysis in Excel, 2010; and Gross Margin (GM). Results suggested that cost effectiveness of feedlot beef did not differ (p>0.05) by genotype; but they differed (p<0.05) by diets. It is concluded that beef feedlots using UTRS was marginally economical at 500 g/day of concentrate supplements. A policy incentive to reduce Breakeven Price (BEP) is suggested. A confirmatory study using actual slaughters is recommended.

Key words: Feedlot beef production, cattle genotype, gross margin, what-if analysis.
