Abstract

OBJECTIVE

To evaluate and update the previously quantified effects of management, marketing, and certified health programs on the sale price of beef calves sold through a livestock video auction service.

DESIGN

Longitudinal study.

SAMPLE

41,657 lots representing 5,042,272 beef calves sold from 1995 through 2009.

PROCEDURES

Data describing each lot of beef calves marketed from 1995 through 2009 by a livestock video auction service were obtained from sale catalogues. For each year of the study, multiple regression analysis was used to quantify the effect of management, marketing, and certified health programs on sale price.

RESULTS

Sale date, base sale weight, quadratic effect of base weight, sex of calf, region of origin, breed description, inclusion in a certified health program, and number of calves in the lot significantly affected sale price for every year of the study. Variation in body weight, flesh score, and number of days between sale and delivery date had significant effects on price in most of the years; frame score and calves with horns affected price in 7 of 15 years; age and source verification influenced sale price in every year since source verification was introduced in 2005; and the auction service's progressive genetics program increased price during the 1 year that program was available.

CONCLUSIONS AND CLINICAL RELEVANCE

Some management, marketing, and certified health initiatives have consistently increased the sale price of beef calves, and producers can increase the price of their calves by implementing these practices.

摘要

目的

评估并更新之前量化的管理、营销及认证健康计划对通过牲畜视频拍卖服务出售的肉牛犊销售价格的影响。

设计

纵向研究。

样本

1995年至2009年出售的代表5,042,272头肉牛犊的41,657批。

程序

从销售目录中获取1995年至2009年由牲畜视频拍卖服务销售的每批肉牛犊的描述数据。在研究的每一年,使用多元回归分析来量化管理、营销和认证健康计划对销售价格的影响。

结果

销售日期、基础销售体重、基础体重的二次效应、牛犊性别、原产地、品种描述、是否纳入认证健康计划以及批次中的牛犊数量在研究的每一年都对销售价格有显著影响。体重变化、肉质评分以及销售与交付日期之间的天数变化在大多数年份对价格有显著影响;体架评分和有角牛犊在15年中的7年影响价格;年龄和来源验证自2005年引入以来每年都影响销售价格;拍卖服务的渐进式遗传计划在该计划实施的1年中提高了价格。

结论及临床意义

一些管理、营销和认证健康举措持续提高了肉牛犊的销售价格,生产者可通过实施这些做法提高其牛犊的价格。
