Evaluation and Selection of Beef Cattle
ثبت نشده
چکیده
In former times, selections in beef cattle were based on conformation alone. Today increased costs of production, competition from other feedstuffs and current exponential growth rates of human populations suggest that while energetic efficiency and volume of production are not the sole over-riding factors in beef cattle production, they are becoming increasingly important. The time has come when factors such as rate and efficiency of growth, carcass composition and dressing percentage must be identified in an empirically measurable form.

This study was an attempt to devise productive orientations of cattle herds in eastern high plains of Algeria. In this regard, 165 farms randomly identified were investigated. The selection of breeders was based to existence of cattle on the farm, and the farmer proposed to investigation must have at least two cows. The approach taken was to identify all systems adopted by farmers in a region t...
متن کاملGenetic Improvement of Reproduction in Beef Cattle
Reproduction is a key profit driver in beef cattle production systems around the world. However genetic evaluation for reproduction traits is generally limited or non-existent. This is likely a function of low levels of recording reproduction traits, and low heritabilities. Traditional BLUP based genetic evaluations have been used effectively in beef for generating estimated breeding values and...

After a workshop in Kuopio held in June 2006, Interbull decided to go forward with the development of a system for beef international genetic evaluation and a three year project called Interbeef was launched in June 2007. The participating countries are so far limited to Europe and the only trait evaluated at present is adjusted weaning weight (weight at 200 days). The results from a first inte...

This study was undertaken to estimate the genetic parameters for some reproduction traits in Sistani beef cattle. The data set consisted of 1489 records of number of insemination, calving, and insemination dates in different calving was used. Reproduction traits including calving interval (CI), gestation length (GL), days open (DO), calving to first service (CTFS), first service to conception (...
متن کاملNational Beef Cattle Evaluation Consortium (NBCEC) White Paper - Delivering Genomics Technology to the Beef Industry
Artificial selection of cattle has been practiced for centuries using a variety of methods and tools. Early selection was based on visual observations that eventually lead to the development of breeds. In efforts to improve production, selection was practiced on measured phenotypic traits with limited success depending on the heritability of the trait. The next big breakthrough in selection too...
