Aflatoxin in Dairy Feeds
Safe levels for aflatoxin feeding vary with each individual animal. The ingestion of aflatoxin at levels even lower than those given above may cause some undesirable side effects. Moreover, these effects are dependent on factors such as age, sex and general health of the animals.

This article includes recommendations on corn hybrid selection for silage, planting, harvesting, storing and feeding corn silage to dairy cows.
Raising Replacement Heifers: What are the Options?
Replacement heifers represent the future of the dairy farm. When deciding the best way to manage the heifer enterprise, dairy producers should realize that they have several options.

Calf Notes is your source for pertinent, non-commercial and unbiased information on raising young dairy calves.
Ration Strategies for Hot Weather
One of the most difficult feeding challenges faced by dairy farmers is the dropoff in feed intake and milk production during the summer. To minimize these losses, rations must be specially formulated for hot weather.

Regulations intended to assure public water safety in the United States have been in place since 1948 under the Federal Water Pollution Control Act. Despite these laws, degradation of public waters continues.
[Image: Lime-Precipitation Unit]Lime Precipitation and Phosphorus Removal from Dairy Wastewater
Nutrient management and recovery on livestock farms, such as dairies, is important for two reasons. The major concern is the gradual buildup in the soil of nutrients such as nitrogen and phosphorus from manure application.
[Image: LSU Southeast research station]En Route to Sustainability of Natural Resources in Dairy Farms
The growing demand for food and fuel in the world has spurred widespread concern about the sustainability of agriculture’s intensive use of energy and nutrients. An easy and cost-effective method to improve nutrient balance in animal husbandry is to reduc inputs.
[Image: Figure 1.]An Economic Analysis of the Dairy Waste Lagoon Clean-out Program in Louisiana
Beginning in 1989, one-cell waste lagoons were being constructed on Louisiana dairy farms as new installations or were modified from established two-stage, aerobic and anaerobic cell lagoons using financial assistance from the U.S. Department of Agriculture under the Environmental Quality Incentive Program (EQIP). Building these types of waste installations continued through 2000.
Using DHI SCC to Manage Bulk Tank Somatic Cell Counts
Electronic measures of somatic cell counts on individual cows can be used to manage somatic cell counts in bulk tank milk.
All Trace Mineral Supplements Are Not Created Equal
When it comes to deciding which mineral supplements to use in livestock feeding, two criteria need to be considered: Biological efficacy and economic efficiency.
Managing Feed Cost
Ration quality and the level of feed consumed both play important roles in maximizing dairy farm profitability. Feedstuff analysis allows better appreciation of real cost and should be considered in ration formulation. Feed efficiency should be calculated and monitored to identify the most profitable cows of the herd and to evaluate the nutritional programs more closely and accurately.

This report is a joint publication of the LSU AgCenter Southeast Research Station, the Hill Farm Research Station, and the Department of Dairy Science. It provides details of research trials at the three locations along with some topical papers of importance to dairy producers in Louisiana.
When Can Calves be Weaned?
Many producers use early weaning programs to lower the costs of feed and labor. Calves tend to scour less when consuming solid feeds compared with liquid feeds. As a result, health costs may decrease.
Using DHI SCC to Manage Bulk Tank Somatic Cell Counts
Bulk tank somatic cell count (BTSCC) is one of several parameters used by state milk regulatory agencies to insure consumers a safe, wholesome milk supply. For dairy producers, this means BTSCC is one item that must be constantly monitored and managed.
