Cattle Value Discovery System

Description

Several segments in the beef industry throughout the world are in transition to managing and marketing cattle individually in feedlots to reduce excess fat produced, increase consistency and quality of products, enhance productivity, and increase economic returns. Therefore, individual cattle management systems are being developed to facilitate marketing individual animals at their optimum economical endpoint, considering live and carcass incremental cost of gain and carcass prices for various grades, and avoiding discounts.

The Cornell/Cattle Value Discovery System model represents an evolution of a growth model first published by Fox and Black (1984) to account for differences in breed type and mature size in predicting performance and profitability of feedlot cattle with alternative management systems. Modifications over the past 25 years have been made to improve its accuracy to account for more of the variation in nutrient requirements and performance of growing beef cattle (Fox et al., 1988; Fox et al., 1992; Tylutki et al., 1994; Fox and Tylutki, 1998). The model as described by Fox et al. (2000) was adapted by the National Research Council for beef (NRC, 1996, 2000) and dairy cattle (NRC, 2001). The model as described by Fox et al. (2004) for growing and lactating beef cattle was used to develop a continuous model to predict responses of dual purpose cattle over the reproductive cycle (Reynoso-Campos et al., 2004).

The CVDS was developed for use in individual cattle management for growing beef cattle. The CVDS provides (1) prediction of daily gain, incremental cost of gain and days to finish to optimize profits and marketing decisions while marketing within the window of acceptable carcass weights and composition, (2) predictions of carcass composition during growth to avoid discounts for under or over weight carcasses and excess backfat, and (3) allocation of feed fed to pens to individual animals for the purpose of sorting of individuals into pens by days to reach target body composition and maximum individual profitability. This allows mixed ownership of individuals in pens, determination of individual animal cost of gain for the purposes of billing feed and predicting incremental cost of gain, and providing information that can be used to select for feed efficiency and profitability.
