Genomic selection is effective in enhancing the selection efficiency during breeding for improved disease resistance in fish. However, given that the collection of routine disease challenge data is generally costly and that disease resistance traits are threshold traits with typically low...

Red swamp crayfish (Procambarus clarkii) is an important aquaculture species in China. With increasing crayfish culture, a number of outbreaks of various diseases have been identified in crayfish. Despite this, there are no reports on the application of disease resistance genes in the molecular...

Sexual size dimorphism is a common characteristic of aquatic animals. However, little is known regarding the differences in immunity that are caused by gender differences in red swamp crayfish (Procambarus clarkii). In this study, the differences in disease resistance between the two sexes of...

The effects of dietary chitosan (0, 2, 4, 6, 8 and 10 g/kg) on the growth, health condition and disease resistance of golden pompano Trachinotus ovatus were evaluated. Dietary chitosan significantly enhanced weight gain, with the highest observed in fish fed the 6 g/kg chitosan diet. This chitosan...

The intensification and diversification of production systems have increased the incidence of diseases, which are usually treated with antibiotics. However, its use should be restricted due to the increasing prevalence of antibiotic-resistant bacteria. Probiotics represent therefore an alternative...

Animal diseases impose a huge burden on the countries where diseases are endemic. Conventional control strategies of vaccines and veterinary drugs are to control diseases from a pharmaceutical perspective. Another alternative approach is using pre-existing genetic disease resistance or tolerance....

Background: Disease resistance phenotypes are associated with immune regulatory functions and immune tolerance and have implications for both the livestock industry and human health. Microbiota plays an essential role in regulating immunity and autoimmunity in the host organism, but the influence...

The present trial was conducted to evaluate whether Biotronic® Top Liquid (BTL) supplementation would benefit during the nursing of Nile tilapia (Oreochromis niloticus) fry in terms of survival, growth, and disease resistance. Isonitrogenous (22.9±0.2% CP) diets were prepared by supplementing 0.0,...

The use of phytobiotic substances as feed supplements in the aquaculture industry is generally increasing because of their safe and positive roles in promoting the performance, antioxidant, and immune responses of several aquatic organisms. In the current study, the stimulatory effects of dietary...

Bacterial consortium containing two bacterial strains such as Paenibacillus polymyxa HGA4C and Bacillus licheniformis HGA8B incorporated in the diet of Oreochromis niloticus at a concentration of 1 × 10⁶ CFU g^-1 (PB1) and 1 × 10⁸ CFU g^-1 (PB2) revealed the probiotic potentials of the bacterial...
