“…We detected Lactobacillus , unidentified Clostridium , Anaerovibrio and Methanobrevibacter key gastrointestinal microflora, by performing the relationship between oxidative stress, immunity and gastrointestinal microflora indicators through Spearman’s correlation analysis. Many studies have reported that the dominant bacteria in the gastrointestinal tract of ruminants are Firmicutes and Bacteroidetes ( Cremonesi et al, 2018 ; Mu et al, 2019 ; Chen et al, 2020 ). Firmicutes are the main bacteria that decompose fiber and cellulose in the rumen, while Bacteroidetes are mainly responsible for carbohydrate and protein digestion and are conducive to the maturation of the gastrointestinal immune system ( Li et al, 2021 ).…”

IntroductionThis study was conducted to evaluate the effects of fermented feed of Pennisetum giganteum (P. giganteum) on growth performance, oxidative stress, immunity and gastrointestinal microflora of Boer goats under thermal stress.MethodsThe study was conducted during 45 days using twenty 2 months Boer goats. The goats were randomly allocated into two groups: NPG (n = 10; normal P. giganteum) and FPG (n = 10; fermented feed of P. giganteum), and the ratio of concentrates to roughage was 3:2. Both groups of animals were kept in sheds and exposed to summer thermal stress from 10:00 h to 18:00 h (temperature and humidity index, THI > 78). At the end of the study, the animals were slaughtered and assessed for various characteristics.ResultsThe findings from the study revealed that FPG-feeding significantly increased (p < 0.05) average daily gain (ADG, 48.18 g) and carcass weight (4.38 kg), while decreased (p < 0.01) average daily feed intake (ADFI, 0.74 kg/d; p < 0.01) and the feed:gain (F/G, 15.36) ratio. The CAT, GSH-Px activities and GSH in serum, liver and spleen, and the levels of IgA, IgG, IgM, IL-2, IL-4 and IL-1β in serum of FPG-fed goats were significantly higher (p < 0.05) than those of NPG-feeding goats. Further, we found that FPG feed is rich in nutrients with Lactobacillus (65.83%) and Weissella (17.80%). Results for gastrointestinal microbiota composition showed that FPG-feeding significantly enhanced the abundance of Lactobacillus and unidentified Clostridiales, and reduced Anaerovibrio and Methanobrevibacter. Meanwhile, Spearman’s correlation analysis showed that these microbiotas were closely related to the improvement of oxidative stress and immune indexes of goats.DiscussionThese results demonstrated that FPG-feeding not only reduces oxidative stress and improves ROS clearance to enhance antioxidant defense system, but also improves gastrointestinal microbiota to enhance immune function by overcoming the adverse effects of heat stress, and further improve growth performance of goats.

“…A recent experiment conducted by Reis et al [ 12 ] showed that supplementation with LPLs improved growth performance and feed efficiency without affecting the DMI of dairy cows. Moreover, Chen et al [ 21 ] found that steers fed diets that contained 1.0% lecithin exhibited higher ADG compared with the control group. In addition, LPL supplementation in lamb diets increased the ADG without affecting feed intake, which is consistent with the current findings [ 11 ].…”

This study was conducted to evaluate the effect of dietary supplementation with lysophospholipids (LPLs) on the growth performance, nutrient digestibility, nitrogen utilization, and blood metabolites of finishing beef cattle. In total, 40 Angus beef bulls were blocked for body weight (447 ± 9.64 kg) and age (420 ± 6.1 days) and randomly assigned to one of four treatments (10 beef cattle per treatment): (1) control (CON; basal diet); (2) LLPL (CON supplemented with 0.012% dietary LPL, dry matter (DM) basis); (3) MLPL (CON supplemented with 0.024% dietary LPL, DM basis); and (4) HLPL (CON supplemented with 0.048% dietary LPLs, DM basis). The results showed that dietary supplementation with LPLs linearly increased the average daily gain (p < 0.01), digestibility of DM (p < 0.01), crude protein (p < 0.01), and ether extract (p < 0.01) and decreased the feed conversion ratio (p < 0.01). A linear increase in N retention (p = 0.01) and a decrease in urinary (p = 0.04) and fecal N (p = 0.02) levels were observed with increasing the supplemental doses of LPLs. Bulls fed LPLs showed a linear increase in glutathione peroxidase (p = 0.04) and hepatic lipase (p < 0.01) activity and a decrease in cholesterol (p < 0.01), triglyceride (p < 0.01), and malondialdehyde (p < 0.01) levels. In conclusion, supplementation with LPLs has the potential to improve the growth performance, nutrient digestibility, and antioxidant status of beef cattle.

“…Additionally, soya lecithin contains several bioactive phospholipids that are essential for vital biological processes (Siyal et al, 2017). The effect of soya lecithin; also called lysolecithin or lysophosphatidylcholine (LPC) on growth performance is variable, as it improved body weight and feed intake in broiler chicken (Ali Siyal et al, 2017), fish (Jafari et al, 2018) and beef steer (Chen et al, 2020), while it did not affect growth performance in pigs (Kim et al, 2008). Feeding soya lecithin decreased the feed intake but increased body weight gain in rabbit does (Attia et al, 2018) but increased the feed intake and body weight gain in growing rabbits (Attia et al, 2018).…”

“…Feeding soya lecithin decreased the feed intake but increased body weight gain in rabbit does (Attia et al, 2018) but increased the feed intake and body weight gain in growing rabbits (Attia et al, 2018). Soya lecithin was found to modulate gut microbiota with positive impact on production, as soya lecithin modified rumen microbiota in beef steer, resulting in modification of the level of ruminal volatile fatty acid production, that was reflected on growth indices (Chen et al, 2020). In mice, the gut microflora shifted in a positive way when fed soya lecithin enhancing the digestive process (Robert et al, 2021).…”

This study aimed at investigating the effect of hydrolyzed soya lecithin; also called lysolecithin or lysophosphatidylcholine, on growth performance, caecal microbiota and fat depots in pre‐breeding primiparous rabbits does. For this, 60 V‐Line primiparous rabbits does (5–6 months) were used in a 30‐day experiment. Does were allotted into three iso‐nitrogenous iso‐caloric dietary treatments (n = 20/group) as follows: (1) CON received 0% soya lecithin, (2) LECL group was fed a basal diet supplemented with 0.5% soya lecithin and (3) LECH group was fed a basal diet supplemented with 1% soya lecithin. Growth performance indices were measured, caecum samples were collected for measurement of specific bacteria via qPCR, and several fat depots including periovarian fat were sampled for adipocyte morphometry and fatty acid profiling. Statistical analysis was performed using GLM procedures of SAS v9.4. Soya lecithin increased feed intake (p < 0.05). The abundance of caecal Bifidobacteria species, Ruminococcus species and phylum Butryvibrio‐specific genes increased (p < 0.05) in rabbits receiving soya lecithin in their diet, soya lecithin increased the level of polyunsaturated fatty acids in subcutaneous and perirenal fat (p < 0.05) and increased the level of monounsaturated fatty acids in periovarian fat (p < 0.05); additionally, the adipocyte area increased in periovarian and perirenal fat (p < 0.05). In conclusion, soya lecithin at a dose of 0.5% increased feed intake and energy storage in adipocytes and improved the fatty acid profile of periovarian fat.
