Corn Silage Management for Lactating Dairy Cows
Corn silage management

This article includes recommendations on corn hybrid selection for silage, planting, harvesting, storing and feeding corn silage to dairy cows.

Environmental Consideration on Forage Quality
Three factors definitely not favorable for optimal plant growth and forage quality are heat stress, drought, and inadequate soil nutrient supply. These problems are very common in Louisiana. Although we may have little control over these environmental influences, we do need to understand the overall effects of environment on forage quality.

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.

Milk Urea Nitrogen Evaluation in Louisiana Dairy Herds
Bulk Tank MUN Concentrations

This article summarizes factors influencing MUN in Louisiana Dairy Herds. Dietary protein has long been recognized as a key nutrient for high milk production in dairy cows, but determining how much protein a cow consumes and how well it is utilized is a difficult undertaking, particularly at the farm level. Interest in the use of milk urea nitrogen (MUN) concentrations as a practical indicator of dietary protein status in dairy cows has grown considerably in recent years.

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.
