At least once a day, many of Idaho’s 550,000 dairy cows wade through shallow copper sulfate baths to help prevent foot infections. Producers often discard the bath water into lagoons and eventually use the spent wastewater to irrigate corn and alfalfa.
“At some point, the buildup of copper in the soil could start to negatively affect crop production,” says soil scientist Jim...

Advances in technology and research have had major impacts on dairy management practices and performance of dairy cattle. With higher levels of milk production, there is a continuing increase in the requirements for energy, protein, fiber, minerals and vitamins. Also, just as important as the nutritional needs of high producing cows are the various management strategies needed to achieve and maintain those higher levels of milk production. In short, the many...

Heat stress occurs in animals when there is problem in thermoregulation i.e., imbalance between heat production within the body (gain) and its dissipation from the body (loss). Increased ambient temperature may lead to enhanced heat gain as compared to heat loss from the body and cause heat stress in animals. India is a true land of diversity in every aspect from culture, food, dress to weather. Scorching heat and freezing cold both the extremes are prevalent in...

Sub-optimum forage quality, lack of proper feedbunk management and lack of properly “steaming” cows up before calving are three areas of the nutritional program which quickly limit profitability on a dairy. The following three articles deal with each of these problem areas and offer ways to make changes in your operation to correct each problem area.

Introduction Traditionally, management of cows during the dry period was minimal. Approximately 60 days before calving, milking would cease and cows were treated with long lasting antibiotic in an attempt to clear up any lingering subclinical mastitis and prevent new infections. Cows were typically removed from the milking herd, given reduced feed, and often exposed to pasture and allowed to "rest" prior to parturition. In the...

Introduction As feedlots are used to finish more cattle, improved strategies evolve. One of the most important management questions once cattle are in the feedlot is "How long to feed them to maximize profit?" However, complex interaction between type of cattle, market demand and price, ownership of the feedlot and/or the cattle, and application of marketing and management tools make profit prediction difficult. Addressing these...

ABSTRACT: Milk is the product of various biological reactions occurring inside the animal's body coupled with external environmental factors. The unfavorable subtropical conditions are not only affecting the quantity of milk but also its quality. The present study was designed to investigate the effect of physiological states and management on milk composition and yield in crossbred cattle. A total of 58 crossbred cows were selected from a large...

Often farmers are plagued with the reality of poor reproductive performance in their herds. Heat detection generally is the single greatest reason for poor reproductive performance in dairy herds today. But what about those farms that are out three times a day watching for heats? Why is their reproductive program still failing? The answer may lie in nutritional deficiencies or imbalances. Outside of diseases or poor management a close look at a farmer’s...

Many new technologies have been made available to the beef industry over the last 50 years. Few technologies have the potential return on investment as do growth promoting implants for nursing calves. The term "implant" is used to refer to a group of products used in the cattle industry that increase rate of growth by placing an absorbable product under the...

Today most dairy producers planning new facilities will at least consider sand bedding as an option. They will talk to other producers, salesmen and other experts and discover a love/hate relationship toward this particular technology. The one thing all do agree on is that sand is definitely different. It has some clear benefits and a definite downside as well.

Given a choice, cows much prefer a mechanical brush to scratching themselves on walls or watering bowls
When you see your cattle rubbing themselves against water bowls, walls or fences, they are just doing what comes naturally. Grooming is a daily ritual for many farm animals and dairy cows are no exception.
About 20 years ago, dairy equipment manufacturers introduced mechanical brush-on-demand devices that help cows groom themselves. Since then, many new free-stall dairy...

New dual-chamber model overcomes previous deficiencies to provide a comfortable option for free-stall operations
During the search for the ideal free-stall base over the last 20 years, one option-waterbeds-has never gained much favour in Ontario. However, it's now attracting interest resulting from recently published research.
Cow waterbeds, first developed in Europe 15 years ago, never caught on in our market for several reasons. The original version had a...

Wisconsin study identifies key management considerations to help keep young animals healthy in calf barns
If you house your calves in hutches like most dairy farmers and you've fed them during a January snowstorm, you may have wondered about moving them into a well-protected barn. If so, you're not alone.
Although individual hutches have long been the standard housing recommendation for raising healthy calves, the number of requests for practical calf barn plans have...

This year I have spent many days at dairies in Minnesota and South Dakota collecting data for an observational study on dairy housing systems (including low profile cross-ventilated freestall barns) and well-being. A lot of the time I am 'stationed' by the return alley scoring cows for locomotion, as well as making observations related to cow movement, behavior, fear of humans and 'contentment.' Certain times during the day, my graduate students and I need to go into the pens to collect...

There have been numerous scientific studies that have shown exposing lactating dairy cows to a long-day photoperiod (LDPP -- 16-18 hours of light and 6-8 hours of dark) in a 24-hour period improves milk production and reproduction performance, that this response persists through an entire lactation, perhaps increasing milk yield as much as 8-10%. This management practice, called photoperiod manipulation, uses a designed lighting system to artificially extend the...
