An Excel workbook, Nutritional Response Determination Optimization (NuRDO). has been developed to simulate the optimal number or nutrient levels and replicates per level when planning nutritional requirement studies. With NuRDO, researchers can simulate data from what they think is the real shape of the response curve. They can then run up to 1,000 simulated experiments to see the combination of levels and replications that minimize the standard error or the requirements and other parameters for the broken-line models. SK and hyperbolic models. For example, consider the BLL model with a “true” requirement (REQ) of 5.2, a maximum of 99 units, a rate constant of 18.6 and a CV of 10%:For 5 input levels and 10 reps per level, the estimated REQ ± SD is equal to 5.196±0. 106, for 10 levels & 5 reps each, the REQ is 5.231±0 .157. The workbook can be used in this manner to determine the best combination of levels and reps to improve the chances or getting the best results possible from experiments.

Water is a critical nutrient that receives little attention until a problem arises. Not only should producers make an effort to provide water in adequate quantity, they should also know what is in the water to be used in evaporative cooling systems and consumed by the birds.

Producers need to be aware of the impacts that manure can have on water and air quality. However, management of manure and other byproducts of livestock and poultry production has important impacts on farm profitability, neighbor relations and protecting soil and water quality.
This publication covers: Farm and Homestead Maps; Manure Storage and Treatment; Nutrient Budgeting with Nitrogen and Phosphorus; Land Application of Manure and Fertilizers; Grazing Land; Pesticide and Chemical Management for Water Quality; Mortality Management; Record Keeping; Coexisting with Neighbors; Emergency Action Plans; and other resources.

Most structural failures in poultry houses are due to a combination of weaknesses in the structural members, including the foundation, walls, trusses and the connections between them. Improvements in any of the factors described in this publication will help the strength of the building.

This publication outlines the information needed to develop a Comprehensive Nutrient Management Plan (CNMP) for dry poultry litter operations.

This publication contains an Excel spreadsheet to help researchers determine the correct poultry population size for their experiments.

The main objective in brooding chicks is to efficiently and economically provide a comfortable, healthy environment for growing birds. Temperature, air quality, humidity and light are critical factors to consider. Failure to provide the adequate environment during the brooding period will reduce profitability, resulting in reduced growth and development, poorer feed conversion, and increased disease, condemnation and mortality.

This publication provides information on (1) the nutrient content of manures available for land application, (2) how to determine manure application rates and whether supplemental fertilizer will be needed for maximum crop production and (3) how to use management techniques to maximize the fertilization potential of farm manures.
