Article Synopsis
- Rising temperatures are negatively impacting duck mortality, laying performance, and meat quality by inducing acute heat stress.
- The study examined how heat stress affects heat shock proteins (HSPs) and antioxidant enzyme activity in the liver of Pekin and Muscovy ducks after exposure to high temperatures.
- Findings showed that Muscovy ducks exhibited better thermal tolerance than Pekin ducks, experiencing less liver damage and more efficient antioxidant responses under heat stress conditions.
The effects of different fatty acid (FA) contents in diet on serum parameters, FA compositions of eggs and meat, and liver morphological changes were studied in Shaoxing laying ducks. A total of 264 ducks at 17 weeks were fed a control diet or a diet containing 30 g/kg fish oil (FO), 25 g/kg sunflower oil (SO), or 30 g/kg palm oil with 20 g/kg beef tallow (PBO). Malondialdehyde (MDA) content in the liver and the serum of ducks fed the PBO diet was significantly (P<0.

The protein encoded by CC chemokine receptor 7 (CCR7) is a member of the G protein-coupled receptor family. This receptor was identified as a gene induced by the Epstein-Barr virus (EBV), and is thought to be a mediator of EBV effects on B lymphocytes. This receptor is expressed in various lymphoid tissues and activates B and T lymphocytes.

- The study examined genetic variation in 12 Chinese native chicken breeds using seven microsatellite DNA markers, focusing on allele frequencies, heterozygosity, and genetic relationships.
- Mean heterozygosity varied among the breeds, with Luyuan chicken displaying the highest value (0.5929) and Chahua chicken the lowest (0.3514), reflecting differences in genetic diversity.
- Fuzzy cluster analysis revealed three distinct genetic groups, with Taihe Silkies chicken and Henan Game chicken being the closest genetically, while Gushi chicken was the most distant from the others.
