Consumers are becoming more interested in where and how their food is made. As a Mid-Atlantic feed supplier, our customers provide protein products throughout the United States and the world. We are proud to serve your business by delivering the quality feed products that your animals deserve while adhering to the traceability and transparency that consumers desire and safety demands.

We create clear and targeted policies, hire the best talent, provide robust training, leverage the power of automation, and prioritize quality over everything.

The Wenger System (WS)

Wenger’s assigns highest priority to management of risk in all aspects of business.  One of the ways the risks in the feed milling and related functions are managed is through the implementation of Wenger System (WS) across the network that addresses the mitigation of known risks, identify potential and new risks, assess acceptable levels, and work for continual improvement. 

The WS is a proprietary centralized resource to every team member in the organization that serves as a dynamic repository of policies, processes and procedures driving continuous improvement in various functions uniformly across all locations aimed at delivering our product (feed) and services consistently every single time.  This is accomplished through ensuring compliance with Internal (operating standards and metrics) and External (local/regional/federal regulatory requirements), enhancing efficiency in functional deliverables and Customer Experience. 

Certified Processes (CP)

Additionally, Wenger Feeds subscribes to management systems complying with standards prescribed by external certifying agencies to ensure the proprietary systems are consistently meeting and improving upon the customer, industry and international standards. These are third party verified, user-fee funded, external audit services, often driven by specific requirements of customers, and include the following.

All the proceedings of the WS and CP are constantly monitored by a high-level management committee and publishes the performance against set objectives and goals on a periodical basis displayed at all the locations.  

The WS and CP are among the key differentiators of Wenger Feeds and are a source of differentiation for its customers in their commitment to uniformity, consistency, quality, safety, compliance, and customer experience.

International Organization for Standardization (ISO) since 2004

Our feed production processes and procedures are ISO certified for following standards at eight of our eleven locations.

ISO 9001: 2015 – Quality

Wenger Feeds uses the standard to demonstrate the ability to consistently provide products and services that meet customer and regulatory requirements.

ISO 14001: 2015 – Environmental

Is an international standard that specifies requirements for an effective environmental management system. It provides a framework that an organization can follow, rather than establishing environmental performance requirements.

ISO 45001: 2018 – Occupational Health & Safety

The goal of ISO 45001 is the reduction of occupational injuries and diseases, including promoting and protecting physical and mental health.

As the only feed mills in North America with triple ISO certification, our customers can trust in quality, safety and environmental compliance at every stage of production — procurement, manufacturing, and delivery.

USDA Organic Logo

Organic, Non-GMO, and Kosher Certified

Our Nutrify ingredient warehouse and two of our feed mills, Shippensburg and Hempfield, are certified to process and handle organic feed and ingredients.  Our organic compliance is certified by Pennsylvania Certified Organic (PCO), Non-GMO compliance by Where Food Comes From.

Our Soy Plant in Rheems has achieved Kosher Certification.


Food Safety Modernization Act

All mills adhere to the Food Safety Modernization Act (FSMA). FSMA aims to ensure the U.S. food supply is safe by shifting the focus to preventing contamination, rather than responding to it. The law applies to human food as well as to food for animals, including pets.

Preventive Controls Qualified Individual (PCQI)

Within the FDA’s Food Safety Modernization Act (FSMA) is a provision known as the Preventative Controls for Human Food Regulation, which prevents foodborne illnesses through the safe preparation of food products for human consumption in the United States. This regulation requires food and beverage facilities to have at least one Preventive Controls Qualified Individual (PCQI) to lead the creation, application, and verification of risk-based preventative controls. PCQI is responsible for preventative controls, compliance, and recall plans. We have 30 individuals from throughout the organization who are PCQI Certified.

USDA Process Verified Logo

USDA Process Verified

Six of our mills are Process Verified through the United States Department of Agriculture’s (USDA) Program.

This verification offers Wenger’s customers a unique way to market their food products using clearly defined, implemented, and transparent process points. As a Wenger customer, you will not have to bear the time and cost associated with single audits as each location will be certified for all Process Verified programs.

Safe Quality Food Logo

Safe Quality Food

Our Rheems and Hempfield Mills are certified to the Safety Quality Food (SQF) standard.

Recognized by the Global Food Safety Institute (GFSI), the Safe Quality Food (SQF) family of food safety and quality codes are designed to meet retailer and buyer needs.

Both mills are certified to food sector category 34, the manufacture of animal feeds, and are audited once a year.

The certification aids our customers who adhere to the program and wish to use the SQF seal on their products as a mark of their commitment to safe food.

Our Custom Feed Formulation

Strategic Nutrition Services

The Nutrition Services team at Wenger Feeds is among the most diversified in the industry offered by a team of highly qualified and experienced Nutritionists entirely focused on performance of customer livestock.  The nutrition services are led by inhouse experts for multiple species that include poultry, swine, dairy and other species and supported by a board of industry advisors that includes leading and seasoned nutrition consultants and veterinarians.

The nutrition function acts as the primary link between the customer and the organization and focuses on delivering standard and customized nutrition programs for each customer driven by their individual market deliverables suiting the breed, life-stage, season, management practices, and market differentiation. Such requirements are tracked by an inhouse system, the WengerWay. Our Nutritionists work closely with its customers in clearly understanding their market goals, analyzing their current challenges, developing fitting nutrition programs, implement in their exclusive situations, monitoring progress, tweaking the programs and continually improving the performance towards delivering the market goals.

This is effectively accomplished through periodical Key Performance Indicator (KPI) meetings with customers. We also actively engage with the industry leaders in updating knowledge on latest developments and innovations and incorporate to customer programs as needed. The nutritionist and research team at TWG continuously and neutrally evaluates various nutritional technologies for target performance requirements and to eliminate or minimize their usage in the nutrition programs in optimizing costs. We keep abreast of nutrition and nutritional technology developments in the industry through presence at leading industry and university scientific meetings  The Wenger Innovation & Research Program supported by four research farms (poultry and swine) support the neutral testing and value determination of innovative ideas and technologies.

The standard nutrition programs offered by Wenger’s include the Conventional (feed with no ingredient restrictions), No Animal Protein – NAP (feed with no proteins from animal origin), Antibiotic Free – ABF (feed with no antibiotics); Raised Without Antibiotics -RWA (feed with no animal protein, medications and ionophores), Organic (feed complying with National Organic Program and Pennsylvania Certified Organic). The Nutritionist team has continues to add several new and innovative programs to its list such as Protein Minimization Program (PMP), Gut Motility Optimization Program (GMOP), Nutrient Absorption Enhancement Program (NAEP), Breaker Egg Program (BEP), Shell Egg Program (SEP), Pigmentation Enhancement Program (PEP), Breast Meat Enhancement Program (BMEP), Pullet Performance Enhancement  Program (PPEP), and Regenerative Agriculture Program (RAP).

Livestock Profitability Modeling Tool

The Nutrition Services team also uses a proprietary tool – Livestock Profitability Modeling Tool –  to engage with customers in understanding and navigating projections of profitability through modeling of various scenarios of their livestock performance.

The nutrition team in collaboration with other functional leaders also works on upskilling the knowledge of nutrition and quality of the team members in their contributions to providing the best customer experience through the Wenger Animal Nutrition Academy (WANA) wherein the participant team members undergo training in advanced modules in anatomy and physiology, nutrition, formulation, quality, food safety and ingredient and feed analysis.


Nutrient Analysis for Better Efficiency of Your Grain

If you’re using your own grain, we can also test its nutrient profile. Nutrient analysis using NIR spectroscopy is a service available in our laboratory. By knowing the nutrient profile of your grain, you can more accurately formulate your feed avoiding costly over-formulation or potentially harmful under-formulation. Contact us to discuss which support program best fits your operation.

Quality Control

 We ensure your animals always receive the right nutrients, we test ingredients, finished feed, and processing conditions for delivery of designed physical form and nutrient aspects of feed.

Our standard Ingredient Approval Process, Supplier Approval Process, and Supplier Monitoring Process ensure the quality and regulatory compliance of all our suppliers and their products.

Our quality management system includes processes to control and regulate ingredients such as medications, lot controls for shelf-life alerts, sequencing and flushing for feeds.

We test actual ingredients and update our ingredient specifications regularly with the current nutrient values. This is important as our feed is manufactured with natural and processed ingredients that vary from factors such as crop cycle location and season.

By closely monitoring our ingredient quality, we can tailor our diets to these changes, reducing nutrient variation, and increasing your confidence.

Mycotoxin Testing

The Wenger Group has a robust Mycotoxin Risk Management program implemented across its mill network.

Mycotoxins are toxic chemical substances that are produced by certain molds found in soil and can be detrimental for animals or humans that consume them.  

We protect your flock or herd by testing for select mycotoxins at the point of receipt for grains using diagnostic strips and also perform a comprehensive test in the laboratory that includes aflatoxins, ochratoxins, T2, DON (vomitoxin), fumonisins, and zearalenones.

With our LC-MS/MS (Liquid Chromatography – Tandem Mass spectroscopy) method we can test for a number of mycotoxins at the same time in any feed, forage, grain, or ingredient.


Biosecurity is a critical component of livestock production, and we are a key part of the food chain. Our biosecurity processes are covered by several procedures in The Wenger System and includes systems in both operations and transportation.


QualQuest, from The Wenger Group, is a consumer-facing mark designed to guarantee quality and food safety. QualQuest enables our customers to differentiate in their business environment and is for today’s consumer, who is extremely informed and concerned with both the animal welfare and the food safety aspects of the products they buy.
