Green tea powder inclusion promoted hatchability through increased yolk antioxidant activity

High albumen height by expression of GALNT9 and thin eggshell by decreased Ca2+ transportation caused high hatchability in Huainan partridge chicken

“… Ergun et al (2017) found that in a certain EST, hatchability was negatively associated with shell thickness in quail. Ling et al (2022) found that feeding green tea powder in laying hens resulted in a thinner eggshell and higher hatchability, which further suggest reduced EST could helpful for hatchability. The different egg weight had no significant effect on the internal nutrients of egg yolk and egg white in HH and LH group.…”

Proteomic Analysis of Egg Yolk Proteins During Embryonic Development in Wanxi White Goose

“…Serotransferrin, responsible for the transfer of iron ions from the fallopian tube to the embryo, , plays a crucial role in cartilage and endochondral bone formation in developing chicken embryos. , It might be transported from the yolk to the developing embryo to maintain embryo cartilage formation, which explained its decreased abundance at D25 of incubation. Serotransferrin also exhibits antibacterial activity against a variety of bacteria, and its antibacterial activity is improved after phosphorylation modification . The phosphorylation of serotransferrin might cause its pI value to be higher than the theoretical value.…”

“…Serotransferrin also exhibits antibacterial activity against a variety of bacteria, and its antibacterial activity is improved after phosphorylation modification. 30 The phosphorylation of serotransferrin might cause its pI value to be higher than the theoretical value. Serotransferrin spontaneously cleaved into peptide fragments with biological properties (such as antibacterial and antioxidant activity), which might explain why the M W of serotransferrin spots was lower than the theoretical value in this study.…”

Dried tea residue can alter the blood metabolism and the composition and functionality of the intestinal microbiota in Hu sheep

“…Green tea and its by-products have been shown to enhance the antioxidant status in animals (Lu et al, 2014). For example, in dairy cows (Ma et al, 2021) and laying hens (Ling et al, 2022), the polyphenolic compounds in green tea can scavenge various oxygen free radicals, including superoxide anion, singlet oxygen, peroxynitrite, and hypochlorous acid (Severino et al, 2009). They can also achieve antioxidant effects by reducing the expression of redox-sensitive transcription factors such as NF-κB and activator protein-1, inhibiting the activity of "pro-oxidant" enzymes, and increasing the activity of antioxidant enzymes such as GSH-Px (Frei and Higdon, 2003).…”
