“…It has been established that exaggerated generation of nitric oxide ( NO ) radical during heat exposure provokes the activation of inflammatory signaling cascades, which stimulates proinflammatory cytokines through animating the transcription factor kappa-B. Inflammatory cells liberate several reactive species at the injury site, bringing on magnified oxidative stress and intestinal tissue damage ( Saracila et al, 2021 ). Conversely, BT has been shown to prevent NO generation markedly by inhibiting the expression of NO synthase, a principal microglial enzyme for NO formation, consequently repressing inflammation in the intestinal wall ( Zhao et al, 2018 ).…”

This research was executed to study the impacts of adding betaine ( BT ) to broiler diets on intestinal inflammatory response and barrier integrity under heat stress ( HS ). At 21 d of age, 150 male broilers (Ross 308) were randomly assigned to 3 treatment groups: control ( CON ) group, in which broilers were provided standard finisher feed under thermoneutral condition (22 ± 1°C); HS group and HS + BT group, in which broilers were given the standard feed supplied with 0 and 1,000 mg/kg BT, respectively, under cyclic HS condition (33 ± 1°C for 8 h from 08:00 to 16:00 h and the thermoneutral temperature for the residual hours). Each treatment was replicated ten times with 5 broilers per replicate. The HS group showed an elevation ( P < 0.05) in serum corticosterone ( CORT ) concentration, D-lactate acid ( D-LA ) content, and diamine oxidase ( DAO ) activity, mucosal interleukin-1β ( IL-1β ) level, and expression of heat shock protein 70 ( HSP70 ) gene, and a reduction ( P < 0.05) in mucosal interleukin-10 ( IL-10 ) level and secretory immunoglobulin A ( SIgA ) content and relative abundance of mRNA for occludin ( OCLN ), zonula occludens-1 ( ZO-1 ), claudin-1 ( CLDN1 ), and claudin-4 ( CLDN4 ). In contrast, broilers in the HS + BT group exhibited a raise ( P < 0.05) in mucosal IL-10 level and SIgA content and relative expression of OCLN and ZO-1 genes, and a decline ( P < 0.05) in serum CORT concentration and DAO activity, mucosal IL-1β level, and expression of HSP70 mRNA. These results indicate that supplemental BT can ameliorate intestinal injury in heat-challenged broilers by suppressing inflammatory responses and enhancing mucosal barrier function.

“…However, in commercial animal production, animals often suffer from bacterial infection ( Zhang X. et al, 2020 ), endotoxin challenge ( Chen et al, 2021 ), mycotoxin challenge ( Xu et al, 2020 ), and weaning stress ( Zhou et al, 2018b ), which may induce a large number of ROS. When the body cannot remove these ROS in time, oxidative stress injury occurs ( Campbell et al, 2013 ; Yin et al, 2014 ; Zhu H. et al, 2018 ; Saracila et al, 2021 ). Numerous studies have demonstrated that oxidative stress is associated with many pathological conditions, including intestinal barrier dysfunction and various digestive tract diseases ( Almenier et al, 2012 ; Navarro-Yepes et al, 2014 ; Cao et al, 2018 ; Tang et al, 2018b ; Chen et al, 2020 , 2021 ).…”

Potential Application of Lonicera japonica Extracts in Animal Production: From the Perspective of Intestinal Health

Lonicera japonica (L. japonica) extract is rich in active substances, such as phenolic acids, essential oils, flavones, saponins, and iridoids, which have a broad spectrum of antioxidant, anti-inflammatory, and anti-microbial effect. Previous studies have demonstrated that L. japonica has a good regulatory effect on animal intestinal health, which can be used as a potential antibiotic substitute product. However, previous studies about intestinal health regulation mainly focus on experimental animals or cells, like mice, rats, HMC-1 Cells, and RAW 264.7 cells. In this review, the intestinal health benefits including antioxidant, anti-inflammatory, and antimicrobial activity, and its potential application in animal production were summarized. Through this review, we can see that the effects and mechanism of L. japonica extract on intestinal health regulation of farm and aquatic animals are still rare and unclear. Further studies could focus on the regulatory mechanism of L. japonica extract on intestinal health especially the protective effects of L. japonica extract on oxidative injury, inflammation, and regulation of intestinal flora in farm animals and aquatic animals, thereby providing references for the rational utilization and application of L. japonica and its extracts in animal production.

“…[4]. In recent years, much attention has been paid to the inclusion of phytochemicals (vitamins, minerals, phytogenic feed additives) with antioxidant properties in the feed mixture, which would overcome the effects of heat stress on poultry health and on the quality of the meat they produce [5]. Some authors have stated that dietary Cr supplementation had a positive effect on meat quality by decreasing the fat content of the carcass, [6] and on carcass traits of broiler chicks in natural [7,8] or heat stress conditions [9].…”

The study evaluated the effect of dietary chromium and vitamin C, Zinc, and sorrel wood powder supplements on chicken health and the nutritional, textural, and sensorial quality of chicken meat. A total of 120 Cobb 500 chickens (heat stress, 32 °C) were assigned into four treatments: control diet (C) and three test diets including 200 µg/kg diet chromium picolinate and supplemented with: 0.25 g vitamin C(VC)/kg diet (E1), 0.025 g Zn/kg diet (E2), and 10 g creeping wood sorrel powder (CWS)/kg diet (E3). Crude protein concentration increased in the breast meat from the E3 group; crude fat decreased in E1 and E3 compared to those fed the C diet. Dietary combinations of CrPic with VC, Zn, and CWS increased redness and decreased the luminosity parameter of breast meat compared with the C group. Dietary combinations of CrPic with VC and CWS lowered the hardness of breast meat. Significant positive correlation was found between hardness–gumminess (r = 0.891), gumminess–cohesiveness (r = 0.771), cohesiveness–resilience-EE (r = 0.861; r = 0.585), ash-L* (r = 0.426), and a negative one between ash–a* (r = 0.446). In conclusion, a dietary combination of CrPic with VC, Zn, and CWS as antioxidant sources could have a beneficial effect on quality without affecting sensory attributes.
