Managing Dietary Phosphorus to Reduce Environmental Impact of Dairy Farms


Introduction

This fact sheet has been developed to support the implementation of the Natural Resources Conservation Service Feed Management 592 Practice Standard. The Feed Management 592 Practice Standard was adopted by NRCS in 2003 as another tool to assist with addressing resource concerns on livestock and poultry operations. Feed management can assist with reducing the import of nutrients to the farm and reduce the excretion of nutrients in manure.

Taking Advantage of Natural Behavior Improves Dairy Cow Performance


Dairy Cow’s Daily Time Budget

Essentially, the 24-h time budget represents the net response of a cow to her environment. Deviations in any herd from these benchmarked behavioral routines represent departures from natural behavior and can serve as a basis for estimating the performance and economic loss due to poor management strategies. Table 1 illustrates a simplified daily time budget for lactating dairy cattle adapted from Grant and Albright (2000) for cows in a free-stall environment.

Prevention and Control of Nitrate Toxicity in Cattle


Introduction

Nitrate intake is closely related to the levels found in forage and drinking water. Forages may contain elevated levels of nitrate when fields are heavily fertilized with manure and nitrogen-containing fertilizer, crops are environmentally stressed by cold, rainy weather with a lack of sunshine in the spring or fall, and drought. Drought-stricken forage may be highest in nitrates for a period of three to seven days following appreciable rainfall. While corn silage often is associated with nitrate problems, …

Comprehensive Evaluation of a Low-Profile Cross-Ventilated Free Stall Barn


Introduction

Low-profile cross-ventilated (LPCV) free-stall buildings are another option for dairy cattle housing. These facilities allow producers to have some control over the cow’s environment during all seasons of the year. They allow buildings to be placed closer to the parlor, reducing time cows are away from feed and water. The overall site footprint of these facilities is smaller than naturally ventilated facilities.

The purpose of this study was to conduct a comprehensive evaluation of the physical characteristics of a …
