Breeding the dairy cow of the future: what do we need?

, 2015
Genetics is responsible for approximately half the observed changes in animal performance in well structured breeding programs. Key characteristics of the dairy cow of the future include (1) production of a large quantity of high-value output (i.e.

Characterization of Dutch dairy farms using sensor systems for cow management.

Journal of Dairy Science, 2015
To improve cow management in large dairy herds, sensors have been developed that can measure physiological, behavioral, and production indicators on individual cows. Recently, the number of dairy farms using sensor systems has increased. It is not known,

Allergenicity, Genotoxicity and Subchronic Toxicity Assessment of IgG Binding Protein LT Produced From Aspergillus oryzae

Journal of Applied Toxicology, EarlyView.
ABSTRACT Gastrointestinal health is one of the fastest growing areas in the food and beverage industry, as its importance to overall health and well‐being is becoming increasingly recognized. Immunoglobulins play a key role in protecting the gastrointestinal tract, and nonbovine sources of immunoglobulins (including camel milk, which has a long history

Establishment of goat mammary organoid cultures modeling the mammary gland development and lactation

Journal of Animal Science and Biotechnology
Background Although several cell culture systems have been developed to investigate the function of the mammary gland in dairy livestock, they have potential limitations, such as the loss of alveolar structure or genetic and phenotypic differences from ...

Staphylococcal mastitis in dairy cows

Frontiers in Veterinary Science
Bovine mastitis is one of the most common diseases of dairy cattle. Even though different infectious microorganisms and mechanical injury can cause mastitis, bacteria are the most common cause of mastitis in dairy cows. Staphylococci, streptococci, and coliforms are the most frequently diagnosed etiological agents of mastitis in dairy cows ...

Bovine papillomatosis belongs to the group of chronic proliferative diseases of viral etiology. Young cattle up to 2 years of age are most often affected. Papillomatosis is caused by the papilloma virus, which forms benign tumors of fibroepithelial properties on the skin and mucous membranes. Usually, the skin form is characterized by the appearance of

Reducing dietary protein in dairy cow diets: implications for nitrogen utilization, milk production, welfare and fertility.

Animal, 2014
In light of increasing global protein prices and with the need to reduce environmental impact of contemporary systems of milk production, the current review seeks to assess the feasibility of reducing levels of dietary CP in dairy cow diets. At CP levels

A review of the development and implementation of the critical source area concept: A reflection of Andrew Sharpley's role in improving water quality

Journal of Environmental Quality, EarlyView.
Abstract Critical source areas (CSAs) are small areas of a field, farm, or catchment that account for most contaminant loss by having both a high contaminant availability and transport potential. Most work on CSAs has focused on phosphorus (P), largely through the work in the 1990s initiated by Dr.

Factors influencing dairy cattle farmer use of antimicrobials on farms in New South Wales, Australia

Australian Veterinary Journal, Volume 100, Issue 12, Page 587-595, December 2022., 2022
Antimicrobial use (AMU) in the food chain is a potential driver of antimicrobial resistance. Despite Australia's strong regulation of AMU limited to veterinary prescriptions, a proportion of empirical antimicrobial treatments are administered by dairy farmers to manage common cattle health problems. This cross‐sectional survey identified key influences
