When to Identify Nonpregnant Lactating Dairy Cows Using Trasrectal Ultrasonography and Why
1. Introduction
Early identification of nonpregnant dairy cows post breeding can improve reproductive efficiency and pregnancy rate by decreasing the interval between AI services and increasing AI service rate. Thus, new technologies to identify nonpregnant dairy cows early after artificial insemination (AI) may play a key role in systematic management strategies to improve reproductive efficiency and profitability on commercial dairy farms.
World Dairy Expo 2010: “Crowning Achievements – Golden Opportunities”
World Dairy Expo will celebrate the global dairy industry in royal fashion, September 28 through October 2, at the Alliant Energy Center in Madison, Wisconsin. More than 65,000 producers and industry enthusiasts from 90 countries are expected to attend the 44th annual event.
World Dairy Expo sets the “gold standard” for industry events, featuring five full days of world-class competition among North America’s top dairy breeders. More than 2,500 head of dairy cattle will parade across the show’s famed, colored shavings. Seven national and international breed shows will culminate with the crowning of World Dairy Expo’s 2010 Supreme Champion. Five breed sales featuring top-shelf genetics will take place on the grounds during the week.
Helping Cows Manage Heat Stress Saves Real Money
More than ever, dairy producers need to save money wherever they can. Especially during the summer months, cows under heat stress can cost producers big bucks. Research has shown that milk production losses alone range from $1.50 to $3 per cow per day.
Silent Threat
Whether a dairy farmer has 20 cows or 20,000, the need for a comprehensive biosecurity plan has never been more important. Even though bioterrorism threats have increased in recent years, international biosecurity is just one element of a sound plan to prevent the introduction or spread of infectious disease in a dairy operation.
National Dairy Board’s 25th
It’s the silver anniversary of the National Dairy Promotion and Research Program . . . but even its supporters acknowledge these are not golden times for dairy producers.
“I think 90% of the dairy producers in the nation are dipping into their equity to stay afloat right now,” says Joe Lyon, a dairyman from Toledo, Iowa. “At this price per hundred pounds of milk, very, very few, if any, are making any money, paying their feed bills, their vet bills and everything. It’s tough, and it’s part of the whole economy…the dairy industry’s in a crisis right now.”
