Determination of digestible indispensable amino acid score (DIAAS) for salmon proteins

Protein quality has relied on methods such as PDCAAS. However, the Food and Agriculture Organization has proposed a new method called DIAAS to better assess protein quality in human foods using the pig as a model. This shift is crucial, not only for optimizing diets, but also for understanding the nutritional value of protein-rich foods. According to the DIAAS method, protein claims can only be made for foods with a score above 75. In general, animal-based foods are considered high quality proteins with score above 75 or 100, being, in most cases, complete proteins that can complement lower quality proteins such as plant-based proteins. Meats, eggs, and fish are examples of high quality proteins, however, salmon proteins are also available, and use of by-products in human consumption has been increasing due to their nutritional value and versatility. Novel sources of salmon proteins such as salmon hydrolysate that may be used in human nutrition have been developed. Salmon hydrolysate proteins contain more than 68% crude protein (CP) and are highly digestible food ingredients, but limited information demonstrating the protein quality of these products is available. Therefore, the objectives of this study were to determine the standardized ileal digestibility (SID) of amino acids (AA) and the digestible indispensable amino acid score (DIAAS) for salmon proteins when fed to growing pigs.

Digestibility of energy by gestating and lactating sows and concentrations of digestible and metabolizable energy in diets containing pistachio shell powder or soybean hulls

California is a leading producer of pistachios in the United States and globally and it is estimated that annual production will reach 2.08 billion pounds in 2031. As a result, about 31.2 million pounds of shells will be produced after the nuts are processed for human consumption. Pistachio shells have been viewed as a waste product and are frequently disposed of using ecologically friendly practices. However, it is possible that pistachio shell powder can be used as a high fiber ingredient for swine. Specifically, gestating sows may benefit from the high fiber concentration in pistachio shell powder because this may increase satiety and reduce stress. However, at this time, there is no information about the nutritional value of pistachio shell powder when fed to sows. Therefore, an experiment was conducted to test the hypothesis that apparent total tract digestibility (ATTD) of gross energy (GE) and concentrations of digestible energy (DE) and metabolizable energy (ME) in pistachio shell powder are not different from those in soybean hulls when fed to gestating sows. The second hypothesis was that the ATTD of GE and DE in pistachio shell powder are not different from those in soybean hulls when fed to lactating sows.
