Summary: This study aimed to evaluate the effect of monosodium phosphate (MSP) and exogenous phytase on growth performance, ileal P digestibility, and bone characteristics in broiler chickens. The results showed that supplementation of MSP or exogenous phytase improved growth performance, ileal P digestibility, bone breaking strength, and bone ash in young broiler chickens.

Summary: Aquaculture effluents high in phosphorus (P) and nitrogen (N) contribute to eutrophication in aquatic ecosystems. This study evaluated the effects of four different inorganic phosphorus sources on P digestibility and excretion in rainbow trout (Oncorhynchus mykiss), with SCP-2% diet showing the best results in terms of nutritional and environmental aspects.

Summary: The study found that reducing dietary phosphorus and fish meal has negative effects on the growth performance of gibel carp, while adding phytase and protease can mitigate these effects by improving digestive ability and immune response.

Summary: The research revealed that high stocking density negatively impacted the growth of gibel carp, with the D-1/2 group achieving complete compensatory growth, while the D-1/4 and D-1/8 groups only partially compensated for the stress.

Summary: This study investigated the effect of D-ribose on the flesh quality of gibel carp. The results showed that D-ribose supplementation improved the nutritional value, texture, and flavor of the fish. It enhanced the water-holding capacity and hardness of the flesh, facilitated the deposition of amino acids and fatty acids, and activated purine metabolism pathways.

Summary: Phytase has been a common addition to poultry diets for over 20 years, showing benefits in growth performance, nutrient digestibility, and bone parameters. This study found that superdosing phytase in rapeseed meal and maize dried distiller grains with solubles diets can improve performance, increase digestibility, and reduce P excretion by 15% compared to birds without phytase.

Summary: The study demonstrated that the digestibility of Ca increased linearly and that of P increased both linearly and quadratically with increasing supplementation of phytase in late gestation and lactating sows. There was no significant effect of phytase on the digestibility of dry matter, crude protein, and gross energy, as well as on the performance of the sows and their offspring. The response to phytase supplementation may be greater in lactating sows compared to late gestation sows.

Summary: Two experiments were conducted to test the effects of microbial phytase on phosphorus digestibility in bakery meal and the replacement of corn with bakery meal in weanling pig diets. The results showed that microbial phytase improved P digestibility in bakery meal and complete replacement of corn with bakery meal reduced growth performance in weanling pigs.

Summary: The two experiments showed that supplemental phytase at 500 and 1500 FTU/kg increased phosphorus digestibility in pigs, regardless of phytase source or feed pelleting. Additionally, feed pelleting increased nutrient digestibility in pigs.

Summary: This study analyzed the impact of Cyprinid herpesvirus 2 (CyHV-2) infection on the gut microbiota and metabolite composition of gibel carp. The results showed that CyHV-2 infection significantly altered the gut microbiota and metabolite profiles, leading to an increase in the opportunistic pathogen Aeromonas. Furthermore, modulation of tryptophan metabolism affected the abundance of Aeromonas, the transcription of antiviral cytokines, and the infection level of CyHV-2.

Summary: The study found that Bdellovibrio has a certain lysing effect on common aquatic pathogens and can significantly reduce the mortality rate of fish caused by infections. Additionally, Bdellovibrio may colonize in fish. These results provide a theoretical basis for the application of Bdellovibrio in aquaculture.

Summary: The age at which birds start feeding on P-deficient diets affects their performance, with younger birds showing lower mortality rates. Increasing phytase activity significantly improves body weight gain, feed intake, tibia ash content, apparent ileal digestibility, and total tract retention of phosphorus in broiler chickens.

Summary: The study investigated the response of gibel carp to dietary lysine levels in zero fish meal diets and found that optimal lysine levels significantly improved growth performance and nutrient absorption in gibel carp. However, excess lysine levels may lead to abnormal physiological indicators, highlighting the importance of controlling dietary lysine levels.

Summary: This study identified the metabolites of 2,2',4,5,5'-Pentachlorobiphenyl (PCB101) in silver crucian carp for the first time, including hydroxylated, methoxylated, and methyl sulfonated PCB101. The investigation of the types and structures of PCB101 and its metabolites, as well as their tissue distribution and accumulation characteristics, is significant for understanding the transformation and metabolic mechanisms of PCBs in aquatic organisms. Identification of precursor compounds and their metabolite pollution hazards on aquatic products and ensuring quality and safety of aquatic products is important.

Summary: This study found that CyHV-2 can establish persistent or latent infection in asymptomatic farmed gibel carp, and different viral mRNA expression patterns were observed in different individuals. This indicates that apparently healthy gibel carp can also be a source of infection.
