Abstract

A vital component of maintaining livestock and other animals' health, productivity, and general well-being is high-quality animal feed. However, a lot of animal research programs frequently use feed compositions that lack thorough nutritional analyses or that use outdated composition techniques, which might result in diets that are not ideal. With the use of cutting-edge near-infrared spectrum (NIR) technology, which provides a rapid and precise assessment. This study intends to evaluate the nutritional value of frequently used animal feed used for such projects by comparing it to both internal and external standards and detect the accuracy of the near-infrared spectrum (NIR). For this purpose, five distinct samples of widely-used animal feed were collected from major farms. Each sample underwent five repetitions and was analyzed using NIR instrumentation and evaluated with multivariate analysis. The analysis covered moisture, protein, lipid, carbohydrate, ash, calcium, phosphate, fiber, neutral detergent fiber (NDF), acid detergent fiber (ADF), acid detergent liquid (ADL), and starch content. The study revealed varying percentages of protein, fat, carbohydrates, minerals, calcium, phosphorus, and fiber in each feed sample. While these percentages differed between feeds, many samples generally met standard specifications for nutritional value. Addition to having a significant influence on animal performance and the quality of the animal output, feed's nutritional value is a major factor in raising animal productivity. Examined animal feeds are safe for use and can help meet the animals' nutritional demands.
