U.S. beef cattle stocks are among the most periodic economic time series. A theory of cattle cycles is constructed on the basis of breeding stock inventory decisions. The low fertility rate of cows and substantial lags and future feedback between fertility and consumption decisions cause the demographic structure of the herd to respond cyclically to ...

Cloning and Stem Cells, 2003
Over the past six years, hundreds of apparently normal calves have been cloned worldwide from bovine somatic donor cells. However, these surviving animals represent less than 5% of all cloned embryos transferred into recipient cows. Most of the remaining 95% die at various stages of development from a predictable pattern of placental and fetal ...

Deep learning-based hierarchical cattle behavior recognition with spatio-temporal information
Computers and Electronics in Agriculture, 2020Behavior is an important indicator for understanding the well-being of animals. This process has been frequently carried out by observing video records to detect changes with statistical analysis, or by using portable devices to monitor animal movements.

Cattle-to-Cattle Transmission of Bovine Tuberculosis
The Veterinary Journal, 2000In developed countries, Mycobacterium bovis infection in cattle is now mostly confined to the respiratory system, which reflects transmission and establishment of infection mainly by this route. A single bacillus transported within a droplet nucleus is probably sufficient to establish infection within the bovine lung.

We report highly pathogenic avian influenza A(H5N1) virus in dairy cattle and cats in Kansas and Texas, United States, which reflects the continued spread of clade 2.3.4.4b viruses that entered the country in late 2021.

Cattle feeding deterrents emitted from cattle feces
Journal of Chemical Ecology, 1991Cattle avoid grazing forage near their feces on pasture for more than a month. The relation of cattle feces odor to the rejection was studied in feeding choice tests using cattle. The feeding deterrent of feces odor was investigated using a trough partitioned to allow passage of feces odor through test food to the cattle.

Emergence and interstate spread of highly pathogenic avian influenza A(H5N1) in dairy cattle
bioRxivHighly pathogenic avian influenza (HPAI) viruses cross species barriers and have the potential to cause pandemics. In North America, HPAI A(H5N1) viruses related to the goose/Guangdong 2.3.4.4b hemagglutinin phylogenetic clade have infected wild birds ...
