Chicken meat quality is becoming increasingly important among breeders and consumers. To understand the effect of feeding conditions on chicken meat quality, we investigated the profiles of genes expressed in chicken breast muscle. Using RNA sequencing, we identified 336, 321, and 387 differentially expressed genes among Chengkou, Daninghe, and Qingjiaoma chickens under scatter- and captivity- ... more

Tumor necrosis factor receptor-associated factor 6 (TRAF6) is a crucial adaptor molecule of the interleukin-1 receptor/Toll-like receptor (IL-1/TLR) superfamily, which can trigger downstream signaling cascades involved in innate immunity. The function of TRAF6 has been clarified in mammals but is poorly understood in chicken. In our study, we investigated TRAF6 function in birds, particularly ... more

Members of the Eimeria genus are protozoan parasites of the subphylum Apicomplexa (Eimeriidae family), and belong to the coccidia group. Eimeria tenella is one of the most pathogenic species owing to its ability to penetrate the mucosa, and cause inflammation and damage. It is an obligate intracellular parasite that causes disease by destroying the host cells during multiplication. Heat shock ... more

Reproductive traits have long been studied and have an important influence on chicken breeding. To identify quantitative trait loci affecting reproductive traits, a genome-wide analysis of a Chinese chicken breed was performed to analyze age at first egg body weight at first egg, first egg weight, egg weight at the age of 300 days, egg weight at the age of 462 days, egg number at the age of ... more

Intense selection for production traits has improved the genetic gain of important economic traits. However, selection for performance and carcass traits has led to the onset of locomotors problems and decreasing bone strength in broilers. Thus, genes associated with bone integrity traits have become candidates for genetic studies in order to reduce the impact of bone disorders in broilers. ... more

Growth traits are important economic traits in broiler chicken production. AluI and Hin1I loci are two restriction sites, which are respectively located in exons 2 and 3 of the IGF-1R gene. These two loci are significantly related to the growth traits in Jinghai Yellow chickens. In this study, a correlation analysis was performed between these two loci and the growth traits of Bian chickens. ... more

This study aimed to evaluate the supplementation levels of an exogenous alpha-amylase in broilers diets and compare two indicators in determining the diets energy. The experiment was divided into two parallel evaluations, being one of performance and the other of metabolism. In performance assay, 1,700 one-day-old Cobb-500 male chicks were used. The animals were distributed in 50 experimental ... more

Four Hyriopsis cumingii populations, a breeding population (BP), a cultured population (FP), two wild populations from Poyang Lake (PY) and Dongting Lake (DT), and an H. schlegelii population were collected (JX), and the first filial generations (F1) were bred synchronously. The shell nacre polymorphisms, population genetic diversity, and genetic structures of the F1 of each population were ... more

We sequenced and characterized the complete mitogenome (KX964606) of the Amur hedgehog Erinaceus amurensis to provide more data for comparative mitogenomics of the genus Erinaceus (Erinaceidae). The mitogenome of E. amurensis is a circular molecule 16,941 bp long, consisting of a control region and a conserved set of 37 genes containing 13 protein-coding genes, 22 tRNA genes, and two rRNA ... more

Fenneropenaeus penicillatus, which is on the Red List of Endangered Species for China, is an important shrimp species. However, there is not enough genetic information on F. penicillatus for conservation and management purposes. Ten microsatellite markers were used to analyze the genetic diversity, genetic differentiation, and population structure of F. penicillatus to provide scientific ... more
