This paper reviews the literature relevant to breeding of cattle grazed in tropical environments and particularly Indonesia. The aim is identify new opportunities for owned by Indonesia’s smallholder farmers, whilst also conserving unique local beef breeds. Crossbreeding has been practiced extensively Indonesia, but date there have no well-designed programs, resulting many mixed-breed animals a...

Recently, an important element in improving the genetic traits of dairy cattle on commercial farms is use interbreeding (crossbreeding). The crossbreeding makes it possible to a variety additive levels between breeds grow individuals with higher economic potential. aim this study was analyze development udder parameters crossbred first-borns compared purebred counterparts and indicators milk pr...

Greater than half of the cattle in the world are managed in tropical environments, while approximately 40% of beef cows in the United States are located in subtropical areas. Furthermore, approximately 80% of global beef production is Bos indicus based. Given this, Bos indicus germplasm plays a critical role in both US and worldwide beef production particularly when used as part of a well-struc...

The dramatic changes and volatility cow-calf production system input costs and calf values have many producers wondering about the value of heterosis in today’s beef industry pricing structure. Many producers are seeking ways to improve cow-calf production efficiency and profitability. Profitability may be enhanced by increasing the volume of production (i.e. the pounds of calves you market) an...

Historically, genetic improvement programs for dairy cattle focused on within-breed selection strategies due to the strong role of breed associations in developing selection policies and a milk pricing system that rewarded volume rather than cheese yield. As a result, Holsteins became the predominant breed in the US and most other major milk producing nations. However, farmers have become incre...

This is an oversimplification, but it will work for this discussion. An animal’s phenotype is observed or measured, but the animal’s breeding value is what is of interest to the sheep breeder. Unfortunately, it is not possible to know the true genetic merit of an animal for a particular trait. Therefore, in order to make selection decisions, its breeding value must be estimated. The animal’s ow...
