Hepatic heat shock proteins, antioxidant-related genes, and immunocompetence of heat-stressed broilers in response to short periods of incubation during egg storage and thermal conditioning.

Short Periods of Incubation During Egg Storage (SPIDES) approach improves chick quality and hatching rates. Also, embryonic thermal conditioning (TC) is a strategy for enhancing thermotolerance in avian species. Until now, evaluating the effect of either SPIDES or embryonic TC effects has only been separately conducted, so we hypothesized that combining TC and SPIDES may enhance the response of broilers to thermal stress.

Tomato pomace as a nontraditional feedstuff: productive and reproductive performance, digestive enzymes, blood metabolites, and the deposition of carotenoids into egg yolk in quail breeders.

This study aimed to evaluate the inclusion of tomato pomace (TP) into Japanese quail breeders' diet by investigating its effects on digestive enzymes, immune response, antioxidant status, blood biomarkers, productive performance, and the deposition of carotenoids into the egg yolk. A total of 150 mature 8-wk of age Japanese quails (100 females and 50 males) were allocated into 5 treatment groups, with 5 replicates, each of 6 quails (4 females and 2 males). The experimental diets were isoenergetic and isonitrogenous, based on corn and soybean meal, and included 0, 3, 6, 9, and 12% of tomato pomace, respectively.

Supplementation of different zinc sources to low-CP diets and its effect on performance, carcass traits, liver and kidney functions, immunological, and antioxidant parameters of quail chicks.

The present study was performed to evaluate the influence of low crude protein (CP) levels, zinc sources (organic as zinc methionine-Zn-Met and inorganic as zinc oxide-ZnO) and their interactions on growth performance, carcass traits, and blood components of growing Japanese quail. A total of 450 one-wk-old Japanese quail with the same body weights were randomly distributed into 9 groups of 50 birds. The 9-diet treatments comprised 3 levels of CP (20, 22, and 24%) and 3 Zn source (0 g of Zn/kg diet, 0.

Neurobehavioral, physiological and inflammatory impairments in response to bifenthrin intoxication in Oreochromis niloticus fish: Role of dietary supplementation with Petroselinum crispum essential oil.

This study was conceptualized in order to assess the 96-h LC of bifenthrin (BF) in O. niloticus and also to measure the biochemical, behavioral, and molecular responses of the fish suchronically exposed to a sub-lethal concentration of the insecticide. The role of Petroselinum crispum essential oil (PEO) supplementation in mitigating the resulted neurotoxic insult was also investigated.

Astragalus polysaccharides alleviate tilmicosin-induced toxicity in rats by inhibiting oxidative damage and modulating the expressions of HSP70, NF-kB and Nrf2/HO-1 pathway.

The present study evaluated the toxic effects of Tilmicosin (TIL) on adult rats. The rats received a single subcutaneous injection of TIL at different doses (10, 25, 50, 75 and 100 mg/kg bw). TIL altered the biochemical parameters including liver and kidney function markers, glucose level and lipid profile as well as resulted in histopathological lesions in liver and adrenal glands mostly in rats exposed to 75 and 100 mg/kg bw.

Yucca schidigera extract modulates the lead-induced oxidative damage, nephropathy and altered inflammatory response and glucose homeostasis in Japanese quails.

The present study was conducted to explore the toxic effects of lead (Pb) on the physiological responses of Japanese quails and to investigate the potential modulatory role of Yucca schidigera extract (YSE) against these effects. 360 mature Japanese quails (at 2 months of age) were used and the experiment was lasted for 8 weeks. The birds were divided into six equal groups as follow: control (basal diet, BD), BD+Pb (100 mg/kg diet), BD+YSE (100 mg/kg diet), BD+YSE (200 mg/kg diet), BD+Pb (100 mg/kg diet) +YSE (100 mg/kg diet) and BD+ Pb (100 mg/kg diet) + YSE (200 mg/kg diet).
