Dairy cattle - Management practices
Welcome to the page about Dairy cattle - Management practices of Engormix; a source of knowledge on Dairy cattle - Management practices.
Ample bedding in stalls can optimize cow comfort, reduce hock lesions and lameness, and increase cow longevity (Tucker and Weary, 2004). The great price increase seen in other more traditional bedding sources has resulted in recycled manure solids (RMS) becoming increasingly common on dairy farms. Recycled manure solids are obtained by mechanical separation of manure removed from dairy cows’ housing systems. Their low cost of recovery,...

Introduction Dairy farming in New Zealand (NZ) is under increasing scrutiny due to growing environmental concerns. Agriculture as a whole is the largest source of greenhouse gas (GHG) emissions (particularly methane and nitrous oxide), accounting for about 48% of NZ's total emissions in 2007 (Ministry for the Environment, 2010). The dairy sector has been deemed responsible for about 36% of agricultural GHG emissions (Ministry for the Environment,...

Dairy Cow Nutrition Nutrient requirements for lactating dairy cows vary with the stage and level of lactation, growth rate and stage of gestation. Most dairy producers in Arkansas feed grain in the parlor as the cows are being milked. This allows producers the opportunity to feed cows according to their level of production and to manage the amount and quality of grain that the cow is consuming. Figure 1 (page 2) shows the...

Horns and Their Growth Horns are the pairs of hard, bonelike, permanent growths projecting from the heads of cattle. They grow from a unique area of skin cells at the base of the horn. At about two months of age, horns become attached to the frontal bone of the skull. A sinus lies within the skull beneath the horn bud. As the horn grows and attaches to the skull, this frontal sinus joins into the adjacent portion of the horn. ...

Shrink results from the stress cattle experience during processing, transporting and marketing, costing both the buyer and the seller. Reducing the stress placed on the cattle during this time will help reduce losses to the value of marketed cattle caused by shrinkage.
Cattle in all age, weight and finish ranges may experience the two kinds of shrink - fill shrink and tissue shrink. Fill shrink, also know as excretory shrink, is the loss of digestive...

Organic dairy production is a system of farm design and management practices for producing milk, yogurt, cheese, cream and other dairy products without the use of pesticides, synthetic fertilizers or antibiotics. For some producers, organic dairy production can be a good fit. There are many factors to consider before making the transition, including current and future milk demand, standards, certification requirements, production costs and lifestyle goals. ...

Here are some of the most asked questions about robotic milking systems. Answers are based on formal interviews with Canadian robot owners, Ontario milk quality records and European research studies.
How many cows will I have to cull because robots cannot milk them?
Ontario farmers reported 0-3 extra culls from an average herd size of 94 cows. These were typically cows with very close teat placement,...

Drought conditions across the country have many beef producers evaluating their feeding costs in an effort to make the correct management decisions for their operations. The information in this publication can be used to analyze dry lot options for your operation or to determine the feasibility of custom feeding cows. Both of these decisions assume that you have taken a full and total inventory of the feedstuffs you have available either as stored forages or grazing acres....

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...
