-
(AgriLife Extension, Texas A&M University System; Texas A&M University. Libraries, )To manage the genetics of beef cow herds, producers should consider several factors in a logical sequence. These factors are production conditions and markets, types of cattle, breeding systems, breeds, and selection of ...
-
(2009-01-27)Animal performance is determined by genetics, environment and the interaction between the two. This publication illustrates the interaction of genetics with physical environment, nutrition, management, and economics.
-
(AgriLife Extension, Texas A&M University System; Texas A&M University. Libraries, )Animal response or performance is determined by two factors—genetics and environment. Environment often brings to mind factors such as climate, topography, and forage properties, but it also includes all other nongenetic ...
-
(AgriLife Extension, Texas A&M University System; Texas A&M University. Libraries, )Body size or mass and milking level are primary genetic traits in beef production. In addition to their direct effects size and milk relate to many other production functions.
-
(AgriLife Extension, Texas A&M University System; Texas A&M University. Libraries, )A logical genetic strategy for a beef cow herd should include four steps. First, determine your production conditions (including climatic, forage and marketing) and the levels of animal performance that fit those conditions. ...
-
(AgriLife Extension, Texas A&M University System; Texas A&M University. Libraries, )More cattle are being marketed on carcass merit. This has prompted greater interest in breeding and feeding cattle that produce desirable carcasses. Improving carcass merit starts with genetic selection—choosing parents ...
-
(2008-03-18)A fundamental challenge in commercial beef production is matching genetic capability with climatic, nutritional, management and market conditions. This publication discusses functional levels of types and breeds of cattle ...
-
(AgriLife Extension, Texas A&M University System; Texas A&M University. Libraries, )The subject of breeds intrigues most beef cattle producers. However, breeds are only part of a genetic strategy
-
(2009-06-17)This publication explains the origin of cattle breeds and reasons for combining them. It also lists the major breeds in Texas and recent breed combinations without registries.
-
(AgriLife Extension, Texas A&M University System; Texas A&M University. Libraries, )What is a breed? A typical dictionary definition is “a race of animals which have some distinctive qualities in common.� One textbook definition is “animals more closely related and alike in appearance than random ...
-
(AgriLife Extension, Texas A&M University System; Texas A&M University. Libraries, )Choosing types of sires is one of the most important decisions for beef producers. That choice should depend on: • Climatic, management, and market conditions • Number of production phases • Breeding systems • Types ...
-
(2009-04-02)Body size is an important genetic factor in beef cattle production. Size is most accurately estimated by considering several factors, such as weight, skeletal size and body condition. Frame Scores are a way of estimating ...
-
(AgriLife Extension, Texas A&M University System; Texas A&M University. Libraries, )Body size is an important genetic factor in beef cattle production. Historically, size was first estimated by measurements such as height or length. As scales were developed, weight became more common as a measure of size. ...

Texas Adapted Genetic Strategies for Beef Cattle XI: Marker Assisted Selection for Beef Improvement (AgriLife Extension, Texas A&M University System; Texas A&M University. Libraries, )
-
(2007-09-19)This publication is an overview of the genetic strategies that can help beef cattle producers have more successful and profitable operations. When managing the genetics of beef cow herds, producers should consider production ...
-
(2009-03-30)Body size and milking potential are important genetic traits in beef production. Wide ranges of body size can be efficient, depending on production environments, breeding systems and carcass specification. Biological ...
-
(2003-08-20)Beef cattle producers face two types of breeding decisions--which animals will be allowed to reproduce and which males will be bred to which females. This leaflet describes various breeding systems in detail and discusses ...
-
(2009-03-30)Choosing types of sires is one of the most important genetic decisions facing beef producers. This publication discusses the factors to consider in matching sires to a cow herd--environmental and management conditions and ...
