As part of the celebration of QualiTru’s 40th anniversary, the team had…
Why is representative sampling for butterfat verification important? Because reliable data equals accurate payment! Butterfat percentages in milk have been on the rise over the last decade, along with a substantial upward trend for butterfat pricing. That’s great news for farmers. It also raises the stakes regarding the accuracy and reliability of the data upon which…
Raw milk string sampling has become increasingly important. This post examines the potential value of string sampling of milk to help nutritionists fine-tune ruminant formulations to provide better information and manage costs. Current feed market prices have milk producers looking for every possible way to manage costs, making the role of ruminant nutritionists increasingly important. We scrutinize…
A peristaltic pump is commonly used to collect a representative milk sample by farmers and veterinarians. There are several reasons to use QualiTru’s sampling system for collecting representative composite samples of milk. These include: Milk quality and bonus payments (Representative Sampling (Direct Load)) Identifying and isolating contamination within the milking process (Inline Sampling) Herd health…
The Lab Pasteurized Count (LPC) estimates the number of bacteria in a raw milk sample that can survive the pasteurization process. Most bacteria are destroyed by pasteurization. However, certain types are not. (Source: Journal of Dairy Science 92(10):4978-87) Lab Pasteurized Count test determines bacteria that are not natural Raw milk can be contaminated by various…
String sampling has traditionally been an affordable and reliable method for monitoring milk quality and udder health on commercial dairy farms. While that application is the most widely used, string sampling offers much more. Do you want to improve efficiency and better manage costs? Other farm applications can benefit significantly by adapting QualiTru’s string sampling…
Standard Plate Count (SPC) directly impacts the quality of raw milk. The quality of the raw milk supply begins on the farm and ends when the product is consumed by consumers. Maintaining the highest quality throughout this chain requires close monitoring and numerous regulations and quality standards for Grade “A” raw milk. SPC measures the…
Guest post: QualiTru is pleased to introduce our guest blogger, Randy Allwardt. He has been a Hygiene Specialist at Prengers Inc. for the past eight years, helping dairy farmers in the Midwest prevent and troubleshoot issues related to milk quality. Dairy farm contamination issues are serious. Accurately identifying a source of contamination is critical for…
The Preliminary Incubation (PI) Count for measuring the quality of raw milk has become increasingly popular since the production of quality milk is the number one goal of dairy farmers and cooperatives. The PI test is especially sensitive to psychrotrophic bacteria. These particular bacteria can grow at colder temperatures, which is why dairy processors are…
Bulk-tank somatic cell counts (BTSCCs) are measured and monitored from Federal Milk Marketing Orders (FMMOs) to determine the quality of the milk supply in the U.S. BTSCCs are defined as the number of white blood cells, secretory cells, and squamous cells per milliliter of raw milk. Milk processors monitor BTSCCs in the nation’s milk shipments…
