Click above to read about a new program that helps pet store operators

help their customers.  Building better relationships.

Based on pet weight and food selection, you provide your customer with the right food amounts

                      and even weight loss suggestions, when appropriate, with your store information on the report.


Here are some Keys to improving field performance. 

Getting the Actual Requirements of the animal, Knowing the Actual Ingredient Contents and Reducing Batch to Batch Feed Variation.  Below are some helpful programs to accomplish this.

BROILER REQUIREMENTS     Click here to calculate Protein and Amino Acid Requirements of Broiler Chicks which are based on age and expected growth by breed. INGREDIENT CONTENTS    Click here to estimate Amino Acid Contents of 23 Ingredients  based on your Proximate Analysis values.  This reduces the expected variation because more is known about the ingred.
FEED VARIATION  Click here to Calculate the Diet Variation due simply to the natural variation of raw materials. Combine with  Requirements for better insights on performance variation. INGREDIENT VALUES FROM EXPERT TABLES    Click here to see Tables of Nutrient Values from around the World

  Variation affects growth more than overall cost.  Use of Proximates (INGREDIENT CONTENTS) to estimate amino acids in feed significantly reduces the variation from the estimates above.  To know more about feed variation, other ingredients, or variabilty's impact on growth, send an e-mail to


To Compute Broiler Chick Protein and Amino Acid Requirements based on unconstrained growth, select a breed, flock sex, and bird age.

This program estimates the amino acid requirements of broiler chicks based on expected growth. This technique does not utilize the Ideal Protein approach but assumes that amino acids are different for muscle growth, maintainence and feathering, based on rate of growth and actual live weight. Increasing or decreasing energy to protein ratio will affect carcass composition and may be desirable depending on market requirements.
