Summary: The study aimed to determine and compare the apparent ileal digestibility (AID) and standardized ileal digestibility (SID) of amino acids in different types of soybean meal, cottonseed meal, and low-gossypol cottonseed meal. The results showed that cottonseed meal and low-gossypol cottonseed meal contained higher levels of arginine and cysteine+methionine, while lower levels of lysine, isoleucine, leucine, and threonine compared to soybean meal. The AID and SID of most amino acids were higher in broilers than in laying hens, and there were significant differences in the AID and SID of amino acids among the three diets.

Summary: A physiologically based pharmacokinetic (PBPK) model was developed for meloxicam in broiler chickens and laying hens to estimate withdrawal intervals (WDIs). The model accurately simulated the distribution and metabolism of the drug in chickens and was converted to a web-based interface for easy prediction. This model provides a valuable tool for assessing the safety of meat and eggs from chickens treated with meloxicam.

Summary: The objective of this study was to determine the energy utilization responses of growing pigs and broiler chickens to autoclaved poultry meal. The results showed that autoclaving time had a significant effect on the metabolizable energy of poultry meal, and the decrease in energy utilization was greater in growing pigs compared to broiler chickens. However, even with a larger decrease in energy utilization, the metabolizable energy in autoclaved poultry meal fed to growing pigs was still higher than in non-autoclaved poultry meal fed to broiler chickens. The ratio of cysteine to crude protein concentration could be used as a potential indicator for estimating the energy utilization in poultry meal.

Summary: This study evaluated the impact of replacing two thirds of a soybean meal-based diet with an alternative protein-based diet on aged laying hens. The results showed that the alternative protein diet did not significantly affect egg production and quality, but it led to darker yolks. The soybean meal diet had higher energy and digestibility, while the alternative protein diet had higher fat content. Therefore, with proper diet formulation, alternative protein-based diets can be fed to aged laying hens, reducing reliance on soybean meal and promoting sustainability in the egg industry.

Summary: This study evaluated the effects of replacing fish meal with full-fat Black soldier fly larva meal (BSFM) on Atlantic salmon fry. The results showed that replacing 5% and 10% of fish meal with BSFM had no negative effects on the growth performance, feed utilization, protein and fat digestibility, or intestinal structure of the salmon. Additionally, the inclusion of insect meal in the diets improved the environmental sustainability of the feed. However, using a BSFM content higher than 10% may not be recommended for Atlantic salmon fry.

Summary: The study demonstrates that black soldier larva meal (BSFM) could be a competitive protein and fat source for fish meal (FM) and fish oil in Atlantic salmon diets. Substituting up to 15% of FM with BSFM showed satisfactory results in terms of growth performance, feed utilization, intestinal health, raw meat quality, and environmental sustainability. This suggests that BSFM can be recommended as an alternative feed component for Atlantic salmon pre-smolts.

Summary: This review aims to provide the latest literature on the processing of insect biomass and its impact on nutritive value. It further discusses the implementation of insect-derived meals and fats in livestock, aquaculture, and companion animal diets, and their effects on growth performance, metabolic response, and gastrointestinal microbiota shifts. The review also addresses the challenges in obtaining unified products in terms of their nutritive value, including defining insects' nutrient requirements and biomass processing. Currently, the limited infrastructure for insect production restricts the use of insect products as functional feed additives in animal diets, with the exception of pet nutrition. More scientific data are needed, particularly as the pet food industry and insect-based diets are rapidly growing.
