Dairy cow monitoring by RFID [PDF]

open access: yesScientia Agricola, 2012
Dairy cows identification and monitoring on small cattle farms are usually based on the utilization of barcode technology. This kind of identification technology is unsuitable for dairy cows milking and feeding process automation. Radio Frequency Identification (RFID) technology is a better solution in this case.

Thromboelastography in healthy dairy cows [PDF]

open access: yesJournal of Dairy Science, 2014
Thromboelastography is a whole blood-based coagulation assay that can be used to investigate hypocoagulability and hypercoagulability, as seen with thromboembolic diseases and disseminated intravascular coagulation. Numerous coagulopathies due to different causes are reported in cows.

A dataset of human-inedible byproduct feeds consumed by dairy cows in the United States

open access: yesData in Brief, 2021
Dairy cows convert human-indigestible forages and byproducts nutrients into edible food for humans [1]. Because of microbiota located in their rumen, dairy cows can digest fibrous forages and feeds which are not exploited by humans and monogastric ...

Contribution of Ruminal Bacteriome to the Individual Variation of Nitrogen Utilization Efficiency of Dairy Cows

open access: yesFrontiers in Microbiology, 2022
High nitrogen utilization efficiency (NUE) is important for increasing milk protein production and decreasing the feed nitrogen cost and nitrogen emission to the environment. Currently, there is a limited whole picture of the relationship between ruminal

Regulation of Milk Protein Synthesis by Free and Peptide-Bound Amino Acids in Dairy Cows

open access: yesBiology, 2021
Milk protein (MP) synthesis in the mammary gland of dairy cows is a complex biological process. As the substrates for protein synthesis, amino acids (AAs) are the most important nutrients for milk synthesis.
