What is dry cow therapy?
This treatment known as Dry Cow Therapy protects the livestock against any intra-mammary infections (IMI) that they may develop or may have contracted during the period of lactation and provides a shield against new infections during the dry period.
How effective is dry cow therapy for strep throat?
Most dry cow therapy products are reasonably effective against environmental streptococci, especially Streptococcus uberis, but they lack activity against Gram-negative environmental bacteria, especially the coliforms. The length of effective protection varies between products, often according to the type of antibiotic or the dose.
When is dry cow treatment appropriate for mastitis?
When subclinical mastitis in a herd has been reduced to a very low level (i. e., every cow in the herd less than 100,000 cells/ml), using dry cow treatment only on selected higher risk cows has been considered appropriate by some dairy producers and veterinarians.
Why are cows treated with antibiotics?
Why do farmers use antibiotics in livestock production? First, antibiotics are used to prevent, treat and control bacterial infections in livestock. Just like humans, animals can contract infections, such as pneumonia. Antibiotics are used to humanely and economically treat and prevent these diseases.
What is antibiotic dry cow therapy?
Dry cow antibiotic therapy is used to eliminate existing intramammary infections and to prevent new infections in the dry period. It is implemented as part of a total management system known as the 'Five-Point Plan' for mastitis control.
What are two advantages of using dry cow treatments?
Dry cow therapy (DCT) is associated with:Curing existing infections at dry off.Decreased risk of new infections during the dry period.Reduced risk of clinical mastitis in early lactation.Decreased somatic cell count (SCC) in early lactation.
What antibiotics treat mastitis in cows?
As a first choice for the systemic treatment of mastitis, either tylosin or erythromycin is recommended. At a dose rate of 12.5 mg/kg, either will maintain for 24 hours milk levels in excess of the average MICs for staphylococci. Of the sulphonamides, sulphanilamide and sulphadimidine produce the highest milk levels.
What is dry cow therapy in dairy cattle management?
Dry cow therapy (DCT) is the treatment of cows at the end of lactation with a long acting antibiotic preparation with or without a teat sealant. This is to treat for any intra-mammary infections (IMI) contracted during lactation and provides protection against new infections during the dry period.
What is the best antibiotic for cattle?
The tetracyclines have been the most widely used antibiotics in the beef cattle industry. (Recently monensin has been approved for use for improved feed efficiency in feedlot cattle. General use by the industry has been rapid. Only tylosin in combination with monensin has been approved for use at this time.)
Why is the dry period of a cow important?
The dry period is the most important phase of a dairy cow's lactation cycle. During this phase, the cow and her udder are prepared for the next lactation; hence any abnormalities during the dry period will have a negative effect on the cow's health and milk production after calving.
What are the benefits of drying off?
The dry-off method, an approach to stop or prepare to stop milking cows at dry-off, is mainly responsible for reducing the risk of new intramammary infections. Dry-off treatment supports the reduction of new infections and treats existing ones.
What are the benefits of cows?

What bacteria causes mastitis?
Mastitis causing pathogens include bacteria (mostly Staphylococcus aureus, coagulase-negative staphylococcus, Streptococcus uberis, Streptococcus dyslactiae, Streptococcus agalactiae, enterococci and coliform bacteria including Escherichia coli) and Mycoplasmas.
Can dry cows get mastitis?
Two important factors related to dry cow management include proper procedures for drying-off cows and a clean, dry environment. Cows are most susceptible to new mastitis infections during the first two weeks of the dry period and the two-week periods both before and after calving.
What is selective dry cow therapy (SDCT)?
Selective dry cow therapy (SDCT), as opposed to blanket dry cow therapy (BDCT), employs a specific strategy to avoid treating every cow with antibiotics at dry off.
How much of the antibiotics used in dairy are BDCT?
BDCT accounts for approximately one-third of the total antibiotic use on a conventional dairy.
What information do producers use to determine cow eligibility for treatment?
In addition to culture results, producers may use additional information gathered from SCC and clinical mastitis records to determine cow eligibility for treatment. There are two culture-guided methods for SDCT.
What is SDCT in dairy?
A selective dry cow therapy (SDCT) program treats some cows at dry off with an antibiotic. SDCT can reduce antibiotic use and costs for dairy farms. All cows should be treated with an internal teat sealant. SDCT is not appropriate for every dairy farm.
What does decreased antibiotic use mean?
Decreased use of antibiotics also means that producers have the opportunity to save money with a SDCT program.
What are the two approaches to classify cows in an SDCT program?
There are two approaches to classify cows in an SDCT program: an algorithm-guided method and a culture-guided method.
Is intramammary infusion good for dairy?
Intramammary infusion with long-acting antibiotics at dry off (dry cow therapy) is a long-standing practice in the dairy industry and for good reason.
What is dry cow therapy?
A dry cow is a cow which isn’t been milked for a couple of months. This is a deliberate rest period given to all dairy cows to recover and recuperate. Treatment and management of dairy cows during this period of inactivity is termed as Dry Cow Therapy (DCT). Dairy cows are prone to conditions such as Mastitis during lactation.
Why is dry cow therapy important?
Sustained Dry Cow Therapy is therefore required to maintain the health of the cows and the quality of milk production.
What determines the frequency of dry cow therapy?
The frequency of mastitis determines the usage of dry cow therapy products. Another aspect worth considering while choosing a line of treatment is the length of the dry period and the milk withhold for the treatment. It is prudent to ensure that the hold is over before the cows enter the milking herd.
What is DCT in dairy?
Selective dry cow therapy (SDCT): is the selective treatment of infected quarters only or all quarters ...
Why do dairy cows get mastitis?
Dairy cows are prone to conditions such as Mastitis during lactation. This disease is characterized by inflammation of mammary glands or udders. It occurs due to multiple reasons usually, bacterial infection introduced either during the milking process or from environmental contact. The degree of infection can range from mild to severe.

What does it mean when a cow's quarters are swollen?
And finally, regularly monitor dry cows for swollen quarters, a sign that indicates intra-mammary infection
Why do dairy cows need antibiotics?
Among these four means of managing infections, antibiotic treatment is the principal method for eliminating cases of mastitis and is the primary reason for using antibiotics in dairy cows. Successful antibiotic therapy involves drugs reaching all sites of infection within the infected quarter, remaining at adequate levels at all sites ...
How to prevent new infections in cows?
Preventing new infections, especially in the dry period; Avoiding drug residues in milk and meat; Keeping existing cases from becoming worse; Minimizing damage to secretory tissues; Reducing spread of existing infections to other cows; and. Improving the overall health of the herd.
Why do you administer intramammary treatment?
In many cases, treatment is administered immediately after milking units are removed, because the udder and teats appear clean due to premilking hygiene as well as the cleansing action of the milking machine. However, the teat end is always contaminated with mastitis-causing bacteria after milking and must be sanitized prior to infusion to minimize the number of bacteria present at the teat that could be carried into the teat canal along with the infusion cannula. These organisms include E. coli, Pseudomonas spp., Prototheca spp., Truperella pyogenes, Nocardia spp., and yeasts. Importantly, many of the aforementioned pathogens are refractory to antibiotics and may render a quarter nonfunctional in severe cases, highlighting the importance of avoiding introduction of these pathogens into the teat,
What is the best treatment for mastitis in dairy cows?
Antibiotic therapy continues to play an important role in the control of mastitis in dairy cows. Lactational therapy is effective against Streptococcus agalactiae but less successful against infections caused by Staphylococcus aureus and other causes of mastitis.
Why is intramammary therapy used in cows?
The purpose of intramammary therapy following label instructions is to help the cow’s natural immune defenses eliminate invading microorganisms. However, the lack of success in curing chronic intramammary infections, particularly those caused by S. aureus and the environmental streps ( S. uberis and S. dysgalactiae) has prompted a reevaluation of treatment strategies. Such infections are frequently refractory to conventional intramammary therapy because locally infused antibiotics are not present at high enough concentrations for a sufficient lengthof time to be effective in killing all the bacteria in the affected quarter.
How to control mastitis in cows?
Among these four means of managing infections, antibiotic treatment is the principal method for eliminating cases of mastitis and is the primary reason for using antibiotics in dairy cows.
How much cure rate for SCC?
A true cure, in which all infecting microorganisms are eliminated from the affected quarter, occurs in less than 50% of cases for most bacterial species. The cure rate is dependent on how long the infection has been present, the age of the cow, the type of organism involved, and other factors such as the SCC at the time that therapy is initiated. Costs associated with treatment of clinical cases include the cost of discarded milk, cost of the drug,and veterinary fees. However, the economic benefits of treatment are less easily recognized because the effecton increasing future milk production, reduction in spread of infections within the herd, decreased chronicity of infection, and decreased culling rates are not obvious.
How many cells per ml of SCC in cows?
In contagious-pattern herds, it may be reasonable in the short term to treat cows with a high SCC (more than one SCC over 250,000 cells/ml) to reduce mastitis cases and infection pressure. However, it’s not a good strategy for controlling mastitis in the medium or long term.
How to treat mastitis in lactation?
If it’s the cow’s first case of mastitis in lactation, start treatment with intramammary tubes immediately. In high-cell-count herds, you can delay treating mild and moderate repeat cases (with only a few flecks in the milk and little or no swelling in the udder) while you assess individual cow history and cell count. In this case, it’s important to segregate these cows from the rest of the herd.
How to check for mastitis after milking?
If you use in-line mastitis filters, check them regularly. After milking, check the main filter or filter sock for any clots or other irregularities that may indicate clinical signs of mastitis. Also, look out for other problems, such as large amounts of soiling due to bad milking techniques or technical problems with the milking plant. A sudden increase in daily bulk milk cell counts could indicate a missed clinical case.
What are the factors that affect cure?
One of the most important factors affecting cure is the length of the treatment course, with longer treatment courses more likely to be successful. To ensure a full bacteriological cure, you should finish treatment courses even if the clinical signs appear cured.
Can antibiotics cure mastitis?
This uses narrow-spectrum, long-acting penicillin antibiotics, which can be very effective.
Can you use antibiotics before calving?
Don’t use antibiotic injections at drying off or shortly before calving. There’s little evidence to show that this improves cure rates any more than using antibiotic dry cow therapy alone.
Should you milk a cow with mastitis?
If not milked last, cows with clinical mastitis should at least be milked with a separate cluster. Don’t use this cluster to milk freshly calved cows or to milk cows with milk out of the tank for reasons other than mastitis.
How long after calving can you use Dry Clox?
Do not use within 30 days of calving. Any animal infused with this product must not be slaughtered for food until 30 days after the latest infusion. Because it is a derivative of 6-aminopenicillanic acid, DRY-CLOX has the potential for producing allergic reactions.
