Dietary Se-Enriched Cardamine enshiensis Supplementation Alleviates Transport-Stress-Induced Body Weight Loss, Anti-Oxidative Capacity and Meat Quality Impairments of Broilers

Abstract

The aim of this experiment was to explore the effects of a new selenium (Se) source from Se-enriched Cardamine enshiensis (SeCe) on body weight loss, anti-oxidative capacity and meat quality of broilers under transport stress. A total of 240 one-day-old ROSS 308 broilers were allotted into four treatments with six replicate cages and 10 birds per cage using a 2 × 2 factorial design. The four groups were as follows: (1) Na2SeO3-NTS group, dietary 0.3 mg/kg Se from Na2SeO3 without transport stress, (2) SeCe-NTS group, dietary 0.3 mg/kg Se from SeCe without transport stress, (3) Na2SeO3-TS group, dietary 0.3 mg/kg Se from Na2SeO3 with transport stress, and (4) SeCe-TS group, dietary 0.3 mg/kg Se from SeCe with transport stress. After a 42 d feeding period, the broilers were transported by a lorry or kept in the original cages for 3 h, respectively. The results showed that dietary SeCe supplementation alleviated transport-stress-induced body weight loss and hepatomegaly of the broilers compared with the broilers fed Na2SeO3 diets (p < 0.05). Furthermore, dietary SeCe supplementation increased the concentrations of plasma total protein and glucose, and decreased the activities of aspartate aminotransferase and alanine aminotransferase of the broilers under transport stress (p < 0.05). Dietary SeCe supplementation also enhanced the anti-oxidative capacity and meat quality in the breast and thigh muscles of the broilers under transport stress (p < 0.05). In summary, compared with Na2SeO3, dietary SeCe supplementation alleviates transport-stress-induced body weight loss, anti-oxidative capacity and meat quality impairments of broilers.

Effect of crating density and weather conditions during transit on preslaughter losses, physiological characteristics, and meat quality in broilers

“…Similarly, the glucose levels demonstrated an interactive effect between crate density and weather conditions in the current investigation wherein broilers transported in high-density crates during hot weather displayed elevated glucose levels, and conversely, those in low-density crates during cold weather also manifested increased glucose levels. The body weight losses followed a similar pattern to the stress markers cortisol and glucose, suggesting a potential association with stress [29]. In contrast to our findings, the research by [20] reported that broilers subjected to high transport density exhibited elevated glucose levels compared to those with low transport density…”

Biogenic Selenium Nanoparticles Synthesized Using Alginate Oligosaccharides Attenuate Heat Stress-Induced Impairment of Breast Meat Quality via Regulating Oxidative Stress, Metabolome and Ferroptosis in Broilers

“…Also, the biogenic SeNPs could enhance Se bioactivity through nanoscale effects to promote the antioxidant properties [41]. Se is a key component of Se-containing proteins and enzymes, such as GSH-Px [42,43], which play a crucial role in the antioxidant defense system [44]. It has been reported that dietary Se enhanced the GPx activity of muscle, which contributed to the improvement of meat quality [45].…”
