Nursing a calf suppresses postpartum ovarian activity prolonging the period of anestrus. Diverse methods are used to reduce the effect of suckling; the most popular, restricted suckling, reduces the number of encounters mother-calf. Temporal weaning of the calf for periods of 24 h, 48 h, or even 72 h also suppress the effect of suckling and is commonly applied to cow-calf operations in the tropics. Early weaning of the calf, usually three to five months after birth, is a practice gaining popularity over the traditional system of weaning at seven months. Furthermore, the use of nose-flaps in the calf to avoid suckling is a common procedure in South America. Finally, weaning during the first week after calving is an established method to reduce postpartum anestrus. The objective of the present review is to discuss the effects of these methods on the reproductive performance of beef cattle and their animal welfare implications.

Genetic Evaluations

The beef cattle industry in the United States has undergone dramatic changes over the past decade with the adoption of genetic evaluation programs. The method of choice has been Henderson's mixed model methodology for best linear unbiased prediction (BLUP). The most prevalently used model is the animal model (Henderson and Quaas, 1976) computed by the equivalent reduced animal model (Quaas and Pollak, 1980).Neither the methodology or the models being used are particularly new. What is new in this industry is the widespread application of these techniques to the analysis of the data banks maintained by the breed organizations. Today many breed associations publish a national sire evaluation, and most of these have published their first in the last three years. This rapid proliferation of published evaluations has coincided with an attitude in the industry of promoting specification beef and predictable performance. Genetic evaluations provide information not only to achieve goals in selection but as well for merchandizing cattle based on quantifiable potential. The enthusiasm for genetic evaluations right now in the U.S. beef industry is high.

Genetic evaluation for beef cattle in Australia has been performed using an animal model with best linear unbiased prediction since 1984. The evaluation procedures have evolved from simple to more complex models and from few to a large number of traits, including traits for reproduction, growth and carcass characteristics. This paper describes in detail the current beef cattle genetic evaluation system ‘BREEDPLAN’ used for the Australian beef cattle industry, the traits analysed and underlying models, and presents a short overview of the challenges and planned developments of coming years.

Abstract Bovine respiratory disease (BRD) is one of the most common and costly diseases of beef cattle. Much research has been conducted to understand prevention, treatment, and economic impacts of this syndrome. Impacts from BRD occur in multiple phases of the beef industry including both pre- and post-weaned calves. This disease causes negative impacts due to production losses, treatment costs, and cattle mortality. The large scope of BRD impacts merits further research on effective prevention and intervention technologies to limit deleterious impacts to the cattle industry.

Subject. This article explores the theoretical basis of the economic efficiency of production and classifies the performance figures of beef cattle husbandry. Objectives. The article aims to define a system of indicators of beef cattle husbandry economic efficiency. Methods. For the study, we used a comparative analysis. Conclusions and Relevance. To assess the economic efficiency of agriculture production, it is necessary to use a set of indicators by beef cattle breeding sub-sector. The system of economic performance indicators of production needs to be transformed into a summarizing indicator. The results of the study can be applied in the theory and practice of determining the economic efficiency of the beef cattle industry.

Abstract A study was conducted to assess the economic impact and knowledge retention of participants that attended the Northeast Georgia Beef Cattle Short course over an eight-year period. The course is an educational program hosted by the University of Georgia Extension Service that brings evidence-based science, technology, and economic and management strategies to Georgia beef cattle producers. The short course is taught annually, lasts a full day, and offers guest speakers and demonstrations from University of Georgia faculty and staff along with industry professionals. Non-formal feedback received from participants showcases its value and supports its continuation, but little is known about how the program impacts beef production in Georgia. The goal of the study was to quantify the long-term impact of the short course while developing an assessment tool that can be used to analyze and improve the course moving forward. Qualtrics was used to distribute a survey to 308 attendees of the short course to gather information on respondents’ role in the cattle industry, knowledge of the concepts taught, comfort level utilizing what was learned, and self-reported economic impact. The response rate was 22% for this study. 41% of respondents are retired individuals, 18% were involved in agricultural production and the remainder of participants represented outside professions. 14% of respondents reported that they believed the knowledge they gained during the short course allowed them to save or gain more than $20 per head. An additional 84% reported an economic impact up to $20/head. The most frequently reported source of cattle information was extension programs, at 17%. Based on these data, Extension has a significant impact on the Georgia cattle industry. In order to further develop the program, the recommendation is made that future courses can be developed to further build relationships with cattle producers and larger operations across the state.

Productivity Gains

The state of Pará has the fifth largest cattle herd in Brazil at 20.3 million heads, and beef cattle breeding accounts for 44.32% of the agricultural production value. Using a recursive econometric model estimated by the generalized method of moments, we evaluated the effects of variables that define the supply and demand of slaughtered beef cattle from 1990 to 2015. The results showed that supply and demand were inelastic to prices. Increases in rural salary and calf prices negatively affected supply, and the response to rural credit applications occurred with a four-year lag due to the biological and technological characteristics of production systems. Deforestation tended to increase the supply of cattle and slaughterhouses appropriated the largest share of the economic surplus generated. There were productivity gains since the early 1990s, with the yield of slaughtered animals was 230.55 kg for cattle and 182.25 kg for cows, while currently, it is 276 and 202.5 kg, respectively. The creation of the Agriculture and Livestock Defense Agency of the State of Pará had a positive effect on the supply of cattle and the expansion of agroindustry structure, contributing to the supply of large markets with higher quality beef.
