About Us

Our Mission

We perform chemical analyses and deliver results with unparalleled speed and accuracy. We strive to offer the best customer service in the industry.

Our History

NJFL was founded in 1950 by Hans Schulze. The company primarily served the Delaware, Maryland, and Virginia poultry feed industry (DelMarVa) and local farmers in the tri-state area. NJFL sought to improve process efficiencies for these producers by providing rapid and independent routine nutritional analysis of their products.

In 1978, Hans’ son Carl Schulze assumed the presidency of the growing business. Along with then-assistant lab manager Pete Cartwright, Carl introduced new chemical technologies and a wider range of testing services. This expanded business scope, coupled with a strict focus on speed and accuracy, attracted more clients to NJFL nationally.

By the turn of the millennium, NJFL was one of the most trusted and respected names in feed and pet food analysis. Carl Schulze announced his retirement on January 1, 2014, after nearly 40 years of service. NJFL is managed by the father and son team of Pete Cartwright (Laboratory Director) and Ian Cartwright (Chief of Operations).

More About Us

An analytical laboratory, New Jersey Feed Laboratory Inc (NJFL) serves the animal feed and pet food industries. Specifically, most of our business derives from the poultry feed industry, the animal rendering industry, and, of course, the pet food/pet treat industry.

We offer chemical analysis, mainly for routine quality control, on all facets of their product lines – from raw ingredients to finished products to byproducts.

Generally, our customers are:

  • QC/QA managers
  • In-house laboratory managers
  • Manufacturing/plant supervisors
  • Any decision-makers in the R&D and manufacturing/production side

Moreover, due to our service’s nutritional and specialized scientific focus, we serve individuals of advanced education and expertise – namely nutritionists and research scientists, who are often consultants to many customers, or employed by universities.

Our company provides three major benefits to its customers:

High-Precision Feed And Pet Food Analysis

Independent laboratories specializing in feed/pet food analysis are rare. Rarer still are those labs that perform only primary instrumental methods and wet chemical testing. NJFL does not, and will never, have a NIRS device on the premises. Many producers do not have the means or facilities to test in-house and rely on an outside lab for routine quality control. Those with in-house testing facilities still need third-party verification and reference of their results. Those that employ NIRS testing still need calibration from the primary analytical results of a lab like NJFL. NJFL is one of only a few independent labs that can fulfill those needs.

Over 70 Years Of Trusted Experience

NJFL is one of the oldest labs in the business with decades of experience and strong quality standards. And we can easily demonstrate proficiency; NJFL excels in quality control programs, typically finishing first or second in competitive series with other labs.

Rapid Results With Exceptional Service

Most importantly, we focus on providing excellent customer service and speedy results. While managing a workflow that ordinarily requires a sizable bureaucratic organization, NJFL maintains a level of customer service found primarily in smaller firms. Our company president personally handles every phone call and email. And we provide results with extreme speed- a two-day turnaround that typically takes other labs a week or more.
