Spray-dried porcine plasma (SDPP) and hydrolyzed porcine protein (HPP) are emerging as high protein ingredients for pet nutrition, especially for formulating diets for carnivorous pets. Derived from the blood of healthy animals, these ingredients are not only sustainable but also nutrient-rich, making them particularly suitable for meeting the increasing demand for high-quality animal protein in pet nutrition.
The objective of this study was to analyze and compare the chemical composition and mineral profiles of SDPP and HPP. The analyses adhered to the stringent standards set by the Association of Official Analytical Collaboration (AOAC) guidelines. For determining the elemental composition, atomic absorption spectrometry was employed, a technique known for its precision and accuracy in trace element analysis.
Protein and Moisture Content
The results of the study indicated that both SDPP and HPP possess low moisture content, with less than 4.3% moisture, which is beneficial for the stability and shelf life of pet food products. Protein content was high in both samples, with SDPP showing a significantly higher protein percentage at 75.4% compared to 71.4% in HPP. This highlights SDPP’s superior protein quality, which is essential for the growth and health of carnivorous pets.
Mineral Richness and Elemental Analysis
Moreover, the mineral richness of these ingredients was confirmed through their crude ash content, which was 12.7% in SDPP and 12.5% in HPP. Key minerals such as sodium (Na), potassium (K), phosphorus (P), molybdenum (Mo), iron (Fe), and zinc (Zn), were analyzed. Notably, SDPP contained high levels of molybdenum, measuring 51.39 mg/100 g, compared to 10.93 mg/100 g in HPP. Molybdenum plays a crucial role in various biological functions, including enzyme processes in animals.
Statistical Significance and Implications for Pet Food Manufacturers
Statistical analysis, using an independent Student’s t-test, confirmed the significance of these findings at a p-value of less than 0.05. The study clearly demonstrates the nutritional benefits of SDPP as a superior protein ingredient in pet diets when compared to similar products. By quantifying these nutrients in raw materials, manufacturers can formulate pet foods that meet the dietary requirements of pets, ensuring their overall health and well-being. This study not only supports the use of SDPP in pet nutrition but also encourages further research to explore its full potential.
