Effects of Different Roughages on Growth Performance, Nutrient Digestibility, Ruminal Fermentation, and Microbial Community in Weaned Holstein Calves.

This study aimed to assess the effects of feeding with different forage sources and starter concentrations on growth performance, nutrient digestibility, ruminal fermentation, and the microbial community in weaned Holstein calves. A total of 54 Holstein calves (body weight (BW) = 77.50 ± 5.

Effect of secondary attack by Aeromonas hydrophila on the expression level of hif genes in common carp (Cyprinus carpio).

Hypoxia-inducible factors (hifs) are involved in infectious diseases inflammatory reactions, and immune regulation. Common carp, a representative allotetraploid species that has undergone genome-wide replication events, has important research value. In this study, common carp were infected twice with Aeromonas hydrophila.

High-Density Linkage Map and Mapping for Sex and Growth-Related Traits of Largemouth Bass ().

The largemouth bass is an important species, and its culture has risen sharply with the surge in fish aquaculture in China. Due to the lack of selective breeding technology for the largemouth bass, the growth rate and disease resistance are low, its sexual maturation is slow, and other serious problems are contributing to a sharp decline in the safety and quality of largemouth bass products in recent decades. Therefore, comprehensive breeding programs to improve the economic performance and promote the modern industrial development of largemouth bass must be considered a priority.

Effects of dietary supplementation of three strains of Lactococcus lactis on HIFs genes family expression of the common carp following Aeromonas hydrophila infection.

HIFs (Hypoxia inducible factors) are the main regulators of the expression change of oxygen-dependent genes, in addition, they also play important roles in immune regulation. HIFs participate in infectious diseases and inflammatory responses, providing us a new therapeutic target for the treatment of diseases. In this study, 16 HIFs were identified in common carp genome database.

Genome-wide identification of interleukin-17 (IL17) in common carp (Cyprinus carpio) and its expression following Aeromonas hydrophila infection.

Interleukin-17 (IL17) family cytokines are well known for having pro-inflammatory actions as important mediators of mucosal immune responses and are tightly regulated by various kinds of signals. However, most studies of IL17 genes have focused on mammals, and much less is known about IL17 genes in fish species. To better understand the scope and actions of the IL17 gene family in common carp, we characterized seven IL17 gene homologs from genomic and transcriptomic databases that could be classified into three subclasses according to different comparative genomic analyses.

Genome wide identification of taste receptor genes in common carp (Cyprinus carpio) and phylogenetic analysis in teleost.

Taste receptors (TRs) are seven trans-membrane G protein-coupled receptors as well as the interface between internal and external milieus, which playing pivotal roles in nutrient identification and acquisition. To better understand the scope and function of tr gene family in common carp, one of the most economic and important breeding fish species, which has undergone an additional round of whole genome duplication (WGD), we characterized 13 tr gene homologues including eight type I and five type II taste receptor genes from common carp genome, which were more than any other teleosts. Phylogenetic and syntenic analysis revealed the evolution dynamics of tr gene family, which was highly conserved, though gene duplication and gene loss do exist recently.

Genome wide identification, phylogeny, and expression of bone morphogenetic protein genes in tetraploidized common carp (Cyprinus carpio).

Bone morphogenetic proteins (Bmps) are a group of signaling molecules known to play important roles during formation and maintenance of various organs, not only bone, but also muscle, blood and so on. Common carp (Cyprinus carpio) is one of the most intensively studied fish due to its economic and environmental importance. Besides, common carp has encountered an additional round of whole genome duplication (WGD) compared with many closely related diploid teleost, which make it one of the most important models for genome evolutionary studies in teleost.
