New
Publications Released by ADSA
The first
two books in the ADSA Scientific Reader Series were published in late January
and early February. The ADSA Scientific Reader Series was created to serve
groups of farmers, extension specialists, producers, processors, scientists in
related fields, and food industry professionals who are interested in the latest
scientific research related to a particular topic. Each book in the series
consists of reprints of peer-reviewed scientific reports that originally
appeared in the Journal of Dairy Science; for those who prefer electronic
access, the articles are also available at a password-protected web site.
The first book in the series, Dairy Management Practices,
Housing, and Cattle Health, was originally created to correspond to the
program at the 2000 NRAES ADairy
Housing and Equipment Systems: Managing and Planning for Profitability@
Conference, it should prove helpful to dairy professionals for many years to
come. The book includes five major sections:
- Housing
and Facility Planning
B
includes scientific reports on practical matters like
planning the milking center, feed bunk length requirements, bedding, cattle
restraints, and competition at the feeding station.
Management
Practices, Nutritional Strategies and Dairy Cattle Health B
includes information on nutrient management,
mastitis, weight gain, computerized feeders, and animal grouping strategies.
Manure
Management B
features a systems approach to manure management, a
discussion of manure spreading strategies, and a summary of a study using
human panelists to assess the effectiveness of anaerobic digestion and feed
additives in reducing manure odor.
Seasonal
Factors and Management Strategies B
this section looks at nutritional strategies for
managing heat stress, strategies for managing reproduction in the
heat-stressed cow, and winter farm management strategies.
- Profitability
and Dairy Management Systems
B
the final section looks at
dairy expansion plans, the profitability of moderate intensive grazing in
the Northeast, characteristics of dairy farms that significantly increased
production, and comparisons of the profitability of dairy farms in various
locations that employed different grazing strategies.
The second book in the series, Mastitis Control and Milk
Quality, was designed to interest registrants at the 2000 National Mastitis
Council Annual Meeting, and will be a helpful reference aid for anyone
interested in preventing or controlling mastitis.
The book includes six major sections:
B
Recent research has found that mastitis can affect
reproductive performance in dairy cows. This chapter contains results of
studies in this area as well as the affects of mastitis on milk yield,
somatic cell count and removal of cows from the herd. Other matters covered
include BST and mastitis and a partial budget of the benefits of mastitis
control strategies.
- Defining
the Mastitis Problem
B
Includes scientific reports
on methods to assess the bacteriological cure of mastitis and on the use of
somatic cell counts to determine uninfected quarters.
B
Mastitis can be a problem in first calf heifers. Reports in
this section look at bacteria associated with clinical mastitis in heifers
and clinical mastitis caused by Escherichia coli in cows.
B
Scientific papers in this section look at the effects
of somatic cell count in milk on yield and quality of cottage cheese and the
affects of subclinical mastitis on the protein fraction of milk. There is a
report on the influence of parity and stage of lactation on somatic cell
count in bacteriologically negative cows. The Delvotest was used in the
detection of antimicrobial substances in cow and quarter milk samples.
Mastitis
Prevention B
Vaccines for mastitis have been a focus of many
researchers in recent years. Six studies on vaccines are reported in this
chapter. Several papers look at management and its influence on mastitis and
somatic cell count. The effects of several milking machine factors on milk
yield, teat condition and udder health are also reported.
Mastitis
Therapy B
This chapter looks at the efficacy of various
treatments on mastitis pathogens in dairy cows. One study looks at the
outcome of lactation therapy on dairy heifers. In another study seven
antibiotic treatments are compared with no treatment. Changes in milk
electrical conductivity was used as an indication of when to treat cows.
Then oxytocin treatment was compared to antibiotic treatment in these cows.
Two studies look at treatment with tilmicosin or cephapirin against
Staphylococcus aureus mastitis, one at dry off and the other during
lactation.

New print and data technologies have made it possible to
create ADSA Scientific Reader Series titles relatively quickly and efficiently.
If you have a topic or question that you would like to see explored in an ADSA
Scientific Reader, and are confident that there is a demand for at least 150
copies of the report, please contact Kent Williamson at 217-356-2426 (extension
