1 Breeding History of Japanese Beef Cattle and Preservation of Genetic Resources as Economic Farm Animals
نویسنده
چکیده
INTRODUCTION Modern beef cattle used for our beef production are not exactly a property left by our ancestors, but composed products from native and imported cattle. Most native cattle were graded up by British and continental breeds for a few generations about 90 years ago. It should be pointed out, however, that they are the sole domestic farm animals in our country contributing to practical animal production at present, originating from our native animals.

A survey of β-lactamase-producing Escherichia coli in farm animals and raw retail meat in Shizuoka Prefecture, Japan.
We surveyed β-lactamase-producing Escherichia coli from farm animals (chickens, pigs, and cattle) and raw retail meat in Shizuoka Prefecture, Japan. In total 305 E. coli isolates, 15 isolates collected from broilers, beef cattle, chicken meat, and pork meat, were found to have β-lactamase genes encoding CTX-M-2, CTX-M-14, CMY-2, SHV-2, and/or TEM-1, whereas 7 possessed mutations in the ampC pro...
متن کاملMethods of Embryo Sexing in Cattle Breeding: A Review
Different livestock sectors as beef industries get benefit from the production of male animals while dairy industries get benefit from the milk production by the female animals. Therefore, it is obvious need to produce the animals of desired sex which can be achieved by predetermining the sex of conceptus at the time of conception i.e. pre determination of sex may be of great economic importanc...
متن کاملDefining Feed Efficiency in Beef Cattle
Most breeding programs have focused on improving economically relevant output traits such as growth, carcass quality and fertility to enhance the economic viability of beef production systems. Generally absent from current breeding programs in the U.S. are avenues for exploiting genetic variation in feed efficiency, even though reductions in feed inputs would substantially improve profitability...

The current review focuses on characterization and conservation efforts vital for the development of breeding programmes for indigenous beef cattle genetic resources in Southern Africa. Indigenous African cattle breeds were identified and characterized using information from refereed journals, conference papers and research reports. Results of this current review reviewed that smallholder beef ...
متن کاملEffect of direct and indirect selection criteria for efficiency of gain on profitability of Japanese Black cattle selection strategies.
The objective of this study was to determine the effect of use of residual feed intake (RFI) and the blood concentration of IGF-I (IGF) as selection criteria for efficiency of gain on profitability of Japanese Black cattle selection strategies with restricted test capacity. A breeding objective that integrated the cow-calf and feedlot segments was considered. Selection strategies were defined t...
