Abstract

The objective of this study was to assess the income and revenues from the sale of boneless cuts of the carcass of 84 Holstein x Zebu crossbred males, non-castrated or submitted to different castration methods at twelve month of age. The animals were randomly divided into four treatments with 21 replications each: castrated with burdizzo, castrated by removing the scrotum apex, castrated with lateral incisions in the scrotum and non-castrated. The slaughter of animals occurred on the same date, at 30 months of age. Carcass primary cuts analysis showed higher forequarter yield in the non-castrated and lower rib cut yield in relation to the castrated animals. Non-castrated animals showed higher weights and yields of deboned chuck and eye round cuts than the castrated animals. Industrial sale revenue of primary cuts analysis showed that the animals castrated by removing scrotum apex were 13.3% less profitable than non-castrated males. However, sale revenues of boneless cuts analysis showed that the lowest revenue income was from animals castrated by lateral incision in relation to non-castrated males (-9.9 %).
