“…We hypothesized that positive effects of the plant extract supplementation on performance will be reflected on markers of systemic oxidative stress, but also on heat stress sensitive tissues such as the liver ( 33 , 34 ) and the intestine ( 12 , 35 ), and on animal products such as the egg ( 36 ). Positive effects of dietary supplementation with CUR extracts and its principal metabolite curcumin have been previously observed in poultry species in the absence of HS ( 37 ), but also specifically in heat-stressed laying hens ( 13 , 14 ).…”

Chronic exposure to high ambient temperatures is detrimental to laying hen performance and egg quality. Plant secondary metabolites may alleviate effects, partly due to their antioxidant activities. Herein, we investigated the effects of dietary supplementation with a phytonutrient solution (PHYTO) consisting of a plant extract combination of Scutellaria baicalensis and Curcuma longa on young layers (25–32 wk of age) raised under naturally elevated temperature conditions. Four hundred, 24-wk-old Lohmann hens were allocated in 50 cages and, after a week of adaptation, were offered a diet either containing 2 g/kg of PHYTO or not, for 8 wk. Hen BW was measured at the beginning and end of the trial, and egg production and feed intake were recorded weekly. At week 32, four eggs per cage were collected to determine egg quality characteristics as well as the rate of lipid and albumen oxidation in fresh eggs. At the end of the trial, two hens per cage were blood sampled for assessment of biochemical markers, one of which was euthanized for histopathological evaluation of the liver and intestine and assessment of intestinal histomorphometry. The herbal mixture supplementation significantly increased egg production rate at weeks 28 and 29 and for the overall production period, and feed efficiency at weeks 26–29. In addition, the degree of liver necrosis and microvascular thrombosis was lower (P < 0.05) whereas intestinal villosity was greater in duodenal and jejunal segments (P < 0.05) in the PHYTO compared to the control group. Supplementation also reduced (P < 0.05) blood concentrations of corticosterone, alanine aminotransferase activity, and TBARS, and a reduction in catalase activity was observed. Egg quality characteristics were not affected, except for eggshell thickness, egg diameter, and eggshell breaking strength that were superior in the PHYTO group (P < 0.05). PHYTO supplementation significantly improved egg lipid oxidation status of fresh eggs. In conclusion, supplementation with PHYTO improved laying hen productivity and egg quality, which was associated with an improvement in laying hen thermotolerance.

“…Stress biomarkers known as heat shock proteins (HSPs) can regulate cellular homeostasis and protein recovery and are additionally produced in excess by stressed cells (Alagar Boopathy et al, 2022). It was also reported that the function of some antioxidant enzymes, such as superoxide dismutase and glutathione peroxidase, were inhibited by exposure of birds to severe stress (Habashy et al, 2019;Muchacka et al, 2018).…”

Endotoxin stress persuaded by the avian pathogenic Escherichia coli threatens egg production and costs the poultry business significantly in lost revenue. This investigation was carried out to determine the beneficial effects of dietary Lactobacillus acidophilus (LA) on laying hens exposed to endotoxic shock induced by intravenously injection of lipopolysaccharides (LPS). A total of one hundred twenty, 40-week-old, laying hens from the Hy-line breed were allocated at random into four groups of 30 hens each. For eight consecutive weeks (40-48 weeks of age), two groups of the layers were given a basal diet as control, while the remaining two groups were given a basal diet enhanced with a 2 g/ kg diet of LA bacteria. At 47 wk of age, layers in one of the control or LA groups received an intravenous injection for 7 consecutive days with 0.5 ml of sterile saline contained LPS at 8 mg per kg of layer body weight, whereas the layers in the other ones of the control or LA groups received intravenous injection of 0.5 ml saline only. The four treatment groups (control, LPS, LPS+LA, and LA groups, respectively) were monitored for their productive performance over the course of the entire experiment (40-48 weeks). At the conclusion of the trial (48 wk of age), stress indicator parameters including body temperature (BT), H/L ratio, plasma malondialdehyde (MDA), and corticosterone (CORT) concentrations were evaluated in the treatment groups (n=10). Additionally, samples of the spleen and duodenum were taken from layers in each group (n=10) to assess heat shock protein 70 (HSP70) density and glutathione peroxidase (GHS-px) activity, respectively. The general linear model procedure with one-way analysis of variance (GLM-ANO-VA) was used to analyze the data. The results showed a significant (P<0.05) increase in the BT, H/L ratio, MDA, and CORT, and over-expression of HSP70 in the hens of LPS group. Also, significant (P<0.05) impairments were perceived in the feed consumption and conversion, and in the egg weight and production rates. In contrast, the elevated stress markers and HSP70 expression in the challenged birds were significantly (P<0.05) alleviated when LA was given to laying hens, and the GSH-px activity was noticeably increased by 13.7% in the LPS+LA compared to the LPS group. Furthermore, LA increased egg production by 8.5 and 3.1 percent points and improved feed efficiency by 6.11 and 4.56% in both LPS-challenged and non-challenged birds, respectively. Therefore, supplementing layer diets with 2 g/kg LA could be successfully applied to improve the productive performance and minimize the endotoxic stress induced by Escherichia coli LPS challenge in laying hens.

“…In some arid regions, exposure of poultry flocks to the hot climate leads to a huge economic drop in the business sector of egg production [ 1 , 2 ]. Heat stress (HS) is a case of imbalance in body thermoregulation and physiological homeostasis of laying hens which dramatically affects their productive performance [ 3 , 4 ]. The reports talked about substantial decrease in egg productivity and feed efficiency of laying hens when affected by acute or chronic HS [ 4 , 5 ].…”

“…It has been documented that HS may affect some biological activities in poultry species [ 8 ], inducing a disturbance in the redox system [ 3 , 9 ], or an elevation in the pro-inflammatory cytokines [ 2 , 5 , 10 ]. Previous studies also demonstrated that HS inhibited the function of antioxidant enzymes, such as superoxide dismutase and glutathione peroxidase, and non-enzymatic antioxidants, such as glutathione and vitamins [ 3 , 11 ]. In a recent study, Abbas et al [ 12 ] found that layers suffering from cyclic HS displayed high levels of plasma corticosterone, lipid peroxidation, interleukin-1β and tumor necrosis factor-α compared to non-HS layers.…”

This study aimed to investigate the role of dietary Spirulina platensis (SP) supplementation in relieving the negative impacts of heat stress (HS) on the productive performance, cholesterol profile, redox status, and inflammatory cytokines of laying hens. A total of 288, 45-wk-old and 1550.7 ± 2.3 g initial body weight, HY-Line W-36 laying hens were housed in two environmental-controlled compartments. Layers were allotted to eight treatments of a two × four factorial design, with six replicates containing six birds per treatment. The temperature in one of the compartments was kept at a thermoneutral condition (24 °C group), while the temperature in the other compartment was raised to a cyclic heat stress of 35 °C from 9:00 a.m. to 5.00 p.m. (35 °C group). Layers in each compartment were fed on one of four experimental diets, containing 0%, 3%, 6%, or 9% SP (SP groups). The trial continued for five weeks. As a result of this study, exposure of laying hens to cyclic HS resulted in a significant (p < 0.05) increase in the total cholesterol (CH), low-density lipoprotein-CH, liver- and egg yolk-CH, ceruloplasmin, malondialdehyde, interleukins (IL-1β and IL-6), and tumor necrosis factor-α, and a significant (p < 0.05) decrease in the high-density lipoprotein-CH, total antioxidant capacity, and reduced glutathione levels. HS negatively (p < 0.05) affected the hen–day egg production (EP, 90.5% vs. 77.0%), egg weight (EW, 61.8 g vs. 56.8 g), feed intake (FI, 111.6 g vs. 101.5 g) and feed conversion ratio (FCR, 2.00 vs. 2.37). As SP levels increased in layer diets, a linear (p < 0.05) improvement response in most of the parameters was obtained in both HS and non-HS layers, recording the best results with 9% SP (e.g., 78.8% vs. 87.6% EP, 56.7 g vs. 61.9 g EW, 103.3 g vs. 110.2 g FI, and 2.38 vs. 2.04 FCR, in 0% vs. 9% SP, respectively). When incorporating SP into the diets of HS-layers, the negative impacts of HS were remarkably relieved (p < 0.05). Therefore, diets containing 9% SP could be used as a promising approach to improve the productive and physiological performance of laying hens, particularly under heat stress conditions.
