Reductions in fish oil content in aquafeeds can generate physiological and immunological disorders in farmed fish, associated to low dietary levels of n-3 long chain polyunsaturated fatty acids (n-3 LC-PUFAs) and increased levels of n-6 PUFAs. Based on mammalian literature, spices could potentially counteract some of these negative effects. To…
The regulation of feed intake in fish is dependent upon different neuroendocrine and metabolic mechanisms including amino acid sensing in the gastrointestinal tract (GIT). However, there is little information regarding the impact of diets on such mechanisms. Therefore, in this study, we fed rainbow trout (Oncorhynchus mykiss) with 3 diets:…
Vitamin E (Vit E) is included at high doses in commercial broiler feeds to boost performance because of its antioxidant function. Phytogenic feed additives with antioxidant properties might be used to spare or replace Vit E as antioxidant and reduce costs. Previous studies with an encapsulated product based on spices…
Essential oils are often used to improve palatability of swine feed. As a natural product, their composition varies, leading to inconsistent results under experimental conditions. Reconstituted versions that mimic the properties and allow standardized blends could clearly demonstrate their effects.
