Deep learning-based hierarchical cattle behavior recognition with spatio-temporal information

Computers and Electronics in Agriculture, 2020
Behavior 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.

Emergence and interstate spread of highly pathogenic avian influenza A(H5N1) in dairy cattle

bioRxiv
Highly 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 ...

Cattle feeding deterrents emitted from cattle feces

Journal of Chemical Ecology, 1991
Cattle 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.

Cattle-to-cattle transmission of Mycobacterium bovis

Tuberculosis, 2001
This review, illustrated with data on the characteristics of herds infected with Mycobacterium bovis (TB) in Great Britain (GB), attempts to identify the role of cattle-to-cattle transmission (CCT) of TB. CCT plays a part in the entry of infection into herds, through purchased infected animals or contiguous spread, although CCT can have a relatively ...

Paratuberculosis in Cattle

Veterinary Clinics of North America: Food Animal Practice, 2018
Paratuberculosis remains one of the most important diseases of cattle worldwide. In cattle, the disease is debilitating and is characterized by weight loss and chronic diarrhea in the later stages of infection. However, cattle in the subclinical stages of the disease often show decreased milk production and are at higher risk for development of other ...

Cattle Behavior and Cattle Handling

American Association of Bovine Practitioners Conference Proceedings, 1986
Reducing stress during handling is important because excitement and other handling stresses can lower conception rate and suppress immune function (Stoebel and Moberg, 1982; Hixon et al, 1981; Kelley et al, 1981 and Blecha et al, 1984). An animal's previous experiences will affect its response to handling (Grandin, 1984).

TG-FTIR and Py-GC/MS analyses of pyrolysis behaviors and products of cattle manure in CO2 and N2 atmospheres: Kinetic, thermodynamic, and machine-learning models

Energy Conversion and Management, 2019
The increased amounts of manure have become an issue of environmental management due to the rapid growth of livestock industry. This study quantified the pyrolytic performance and gaseous products of cattle manure using (derivative) thermogravimetric ((D)
