Supplemental effects of coated omega-3 polyunsaturated fatty acids to basal diet on improving growth performance, nutrients digestibility, fecal lactobacillus count and fecal score in weaning pigs

Effect of purified docosahexaenoic acid supplementation on production performance, meat quality, and intestinal microbiome of finishing pigs

“…Dietary supplementation with 0.5%, 0.10%, and 0.15% purified DHA resulted in improvement in BW, ADG and G:F of pigs, which was similar to the report of Zhang et al (2020). Upadhaya et al (2016) demonstrated that application of 0.75% n-3 fatty acid from linseed oil increased ADG in pigs.…”

“…Using 1% n-3 fatty acid, Sun et al (2019) did not report any improvement in DM, nitrogen, and energy digestibility in week 5, with the exception of an increased energy digestibility score at week 10. Zhang et al (2020) observed increased DM and nitrogen digestibility with the application of n-3 fatty acids in wean-ing pigs. Increased fat digestibility was recorded in the experiments of Upadhaya and Kim (2021).…”

“…Previous studies have suggested some other possible reasons such as increased fat digestibility (Upadhaya and Kim, 2021) and increased energy digestibility (Sun et al, 2019). Zhang et al (2020) argued that a positive response in growth performance to the use of n-3 fatty acid supplementation could be associated with a reduced antigen overload and improved digestibility. In contrast, Overland et al (2015) using 1% fish oil, Upadhaya et al (2016) using 0.75% n-3 fatty acid, and Rodriguez et al ( 2017), using 1.5% fish oil, reported no effect on ADG, ADFI, and G:F. Possible reasons for these inconsistent results could be differences in animal age, dose, and composition of the test product.…”

“…Fish oil is one of the main sources of fat that contains omega 3 fatty acid components. Sun et al (2019) and Zhang et al (2020) reported improved growth performance in pigs as a result of supplementing fatty acids from fish oil. Fats and oils play an important role in feed ingredients due to their high energy value and ability to absorb certain vitamins and minerals.…”

The Impact of Weaning Stress on Gut Health and the Mechanistic Aspects of Several Feed Additives Contributing to Improved Gut Health Function in Weanling Piglets—A Review

“…Their mechanism of action has been suggested to be due to the obstruction in the essential bacterial processes at the pathogen membrane level through the disruption of electron transport chain, uncoupling of oxidative phosphorylation, and cell lysis [ 134 , 135 ]. A study by Zhang et al [ 54 ] reported that supplementation of coated omega-3 fatty acid at the doses of 5, 10, and 15 g/kg showed trends in linear reduction in fecal E. coli counts and increments in Lactobacillus counts, suggesting that omega-3 fatty acid can also modulate gut microbials and enhance gut functions. In another study, Hanczakowska et al [ 53 ] reported that supplementation of 2 g/kg capric or caprylic acid improved performance and mucosal epithelium structure of ileum in weaning pigs.…”
