Near-Infrared Reflectance Spectroscopy (NIRS) is a technique used to determine the chemical composition of materials. The GAN Lab uses NIRS to analyze fecal samples, providing information on diet quality and digestibility to help optimize management practices. More information is available here.
NUTBAL is a Nutrition Balance Analyzer software used by the GAN Lab in conjunction with the fecal NIRS (FNIRS) analysis. It incorporates the outputs of the FNIRS analysis with animal and environmental descriptions to provide insights into nutritional status. NUTBAL helps the user make informed decisions on animal management, including mitigation of projected weight or body condition gain/loss, and either grazing or supplemental feeding strategies. More information is available here.
The FNIRS/NUTBAL System combines the outputs of the FNIRS analysis with animal and environmental descriptions to inform the NUTBAL software. This system helps optimize decisions on management by estimating weight and body condition gain/loss, helping producers to determine the timing of stocking rate, pasture rotation, or supplemental feeding strategies, and suggesting types and amounts of supplemental feed to achieve performance goals.
NIRS/NUTBAL Standard Report ($45): This baseline service is recommended for individuals comfortable with inputting data and interpreting animal nutrition outputs.
NIRS/NUTBAL Advisory ($80): Recommended for those new to animal nutrition analysis or seeking more information and feedback on the fecal NIRS/NUTBAL results.
The NIRS/NUTBAL Advisory service offers comprehensive analysis and interpretation of fecal NIRS/NUTBAL results, providing additional guidance and insights for those new to animal nutrition analysis or seeking detailed feedback. Depending on the complexity of the analysis, it may involve follow-up by GAN Lab personnel to verify inputs and refine recommendations.
Yes, the GAN Lab provides research services and special prices. If you have specific research needs, please contact us.
The process is simple:
Step 1: Request a fecal sample kit: Contact us by phone or email (ganlab@brc.tamus.edu) to request a fecal sample kit. The kit includes instructions and materials for collecting and mailing your sample.
Step 2: Prepare your sample to mail: Follow the provided instructions to collect your sample and prepare it for mailing.
Step 3: Mail in your sample: Send your prepared sample to the address provided in the kit. Once received, our lab will conduct the analysis and provide you with the results.
Yes, the NIRS/NUTBAL System can be applied to cattle, and the FNIRS analysis can be applied to ruminants like sheep, goats, and wildlife, as well as non-ruminants like horses. It is also applicable for different grazing environments, ranging from pasture-based systems to more intensive production systems.
The NIRS/NUTBAL System has been extensively validated and refined to ensure accuracy and reliability. However, it’s important to note that like any analytical technique, there may be inherent limitations and variability. Please visit our Publications page to see research articles in which the FNIRS/NUTBAL System has been applied.
The frequency of fecal sample analysis depends on various factors, including the specific needs of your management program, seasonal changes in forage quality over the year, and any observed changes in animal performance. Our team can work with you to develop a strategy that aligns with your goals and circumstances. For personalized assistance, please don’t hesitate to contact us. If you’re participating in one of our contracts, you can find more information here.
Yes, in addition to the standard report or advisory services, clients can access educational materials, and webinars available on our Publications page and YouTube channels.
Yes, the Center for Natural Resources Information Technology (CNRIT) offers complementary resources and expertise to enhance the integration of the NIRS/NUTBAL System with other management tools or platforms. For more information, please visit: CNRIT Website.
The GAN Lab is dedicated to delivering prompt results to our clients because we understand how crucial it is to receive the results in time for management decisions. Usually, you can expect to receive results within 2-4 business days after the lab receives the sample. However, this timeframe may vary depending on factors such as sample volume, lab workload, and shipping logistics.
Yes, by regularly analyzing fecal samples and tracking changes in the diet composition and nutritional status of the animals over time, managers can access the effectiveness of their grazing management strategies and make informed adjustments as needed to optimize animal health and performance.
