Genetics and Milk Quality

Dairy producers are offered many opportunities to try new products and technologies.  While new opportunities frequently promote their positive aspects, it is important to consider any potential negative aspects.  What do you think that your response would be if you had to choose between these 2 products?  Both products have the same cost to purchase and the same implementation protocol.

Jennifer Walker, Director of Milk Quality, Danone North America

Jennifer Walker joined Danone North America (DNA) as Director of Milk Quality in May of 2018, her primary duty to manage milk quality and food safety from farm to factory gate for the 600+ farms in DNA’s direct supply network in addition to all liquid dairy supply (cream and condensed). Since then, the team has taken on and incorporated animal welfare into their quality mission having launched DNA’s industry leading Quality and Care program (QnC). The QnC team consists of six specialists focused on translating audit and quality data into results at the farm or supplier level.

Detection, correction, and prevention of milking equipment problems on dairy farms

As herds aspire to achieve higher levels of milk production and milk quality there is a need for more focused management of all areas of the farm. The management of the milking center and its associated equipment is no exception to this. In order to achieve success with the milking center the first step is to document what the current baseline is for all the major areas affecting the milking center. For this paper, I will be specifically focusing on the milking equipment portion of a baseline data set but when evaluating farms it is very important to remember that all the components are interwoven together and influence each other.

• Milking cluster: Rinsing of the milking cluster, ideally after every cow, helps avoiding spread of infection between cows during milking.

Current knowledge and application of biosecurity in cattle

Biosecurity is defined as the combination of all measures that can be taken to reduce the risk of introduction and spread of disease agents between animals. As such, the implementation of biosecurity is an important tool to accomplish disease prevention on cattle farms. It contributes to animal and public health and welfare, but it can also improve economic results and lower antimicrobial use and resistance.

Stem cell research shows promise as natural mastitis treatment

Mastitis remains the single most challenging infectious disease faced by dairy farmers across the world. Producers and herd managers rely on a series of approaches to control and treat mastitis, including genetic selection, environmental management, nutrition, and selective dry cow therapy. In combination with strict hygiene protocol and other treatments, such as the use of teat sealants, headway can be made. Yet, mastitis persists. For the most part, veterinarians and dairy farmers have relied on antibiotics to treat mastitis. While they do work, they do not repair the tissue damage caused by infection, which can lead to abnormal and decreased milk production. Amid rising resistance to antibiotics, it is ever more important to find new and novel solutions for treatment.

Patterns of mastitis indicators during a clinical mastitis episode

Mastitis is one the most common and costly diseases of dairy cattle, hence widely studied globally. It is the inflammation of one or more quarters of the mammary glands, mostly caused by various microorganisms. Based on whether gross changes in milk (such as watery, serous, or purulent milk, presence of clots, flakes, or blood), gross changes in the udder (such as painful or inflamed udder) and animal are seen or not, mastitis is categorized either into clinical or subclinical. With the introduction of Automatic Milking Systems (AMS), the sensors can measure milk parameters every time the cow goes for milking.
