In a 10-wk study, alterations in the rate of fertility, egg viability, and hatch parameters of adult geese exposed to different breeding methods were investigated. Twenty-four matured geese (4.0 ± 0.45 average weight) were randomly divided into three groups (TNM-natural mating group, TIM-artificial insemination group, TNI-natural mating and insemination group) of two replicates with four geese per replicate in a completely randomized design. Fresh semen collected from six ganders (5.2 ± 0.69 average weight) was pooled and used to inseminate the geese in TIM and TN1 at 0.2Ml at insemination times. The geese in TNM and TNI were allowed to mate naturally. Insemination and mating was done at 3 d interval and eggs from each treatment were collected daily. Incubation of eggs was done weekly, candling and transfer to hatcher were done on day 27 and goslings hatched out on day 30. Fertility, early embryo mortality (EEM), mid embryo mortality (MEM), late embryo mortality (LEM), hatch of fertile eggs (HOF), and hatch of set eggs (HOS) were obtained and analyzed using descriptive statistics and ANOVA and means separated using least significant difference test. Geese in TNI had significantly higher fertility (93.33 ± 10.97%) than TNM (59.67 ± 31.29%) and TIM (83.60 ± 17.14%). The EEM was higher in TIM than in the two other groups while the HOF and HOS were higher in TNM and TNI than in TIM. This study suggests that in comparison with TIM, higher fertility, hatchability, and lower embryo mortality can be obtained when geese are inseminated and naturally mated simultaneously.

Disruption of developmental processes affecting the fetal lung leads to pulmonary hypoplasia. Pulmonary hypoplasia results from several conditions including congenital diaphragmatic hernia (CDH) and oligohydramnios. Both entities have high morbidity and mortality, and no effective therapy that fully restores normal lung development.

Epilepsy, the most common neurological disorder worldwide, is characterized by sudden paroxysmal brain activity, which can be generalized or focal. Extensive research has explored various treatment strategies for this condition. Our study employed a pilocarpine (PL)-induced seizure model in zebrafish (Danio rerio) embryos and larvae to assess the effects of carbamazepine (CBZ)-loaded chitosan-coated PLGA-Zein nanoparticles (NPs) over 96 hours.

Pigeon paramyxovirus type-1 (PPMV-1) is the causative agent of pigeon Newcastle disease (ND), which has caused huge losses to the pigeon industry. In this study, a PPMV-1 strain, PPMV-1/QH-01/CH/23, was isolated from a sick racing pigeon in the Qinghai-Tibet Plateau, China in 2023. The mean death time of chicken embryos and the intracerebral pathogenicity index (ICPI) were 76.

As a representative agent of bicyclic antidepressants, venlafaxine (VEN) has become widely used worldwide and is frequently detected in surface waters with concentrations ranging from ng/L to µg/L. To evaluate the toxicological effects of such medications on aquatic species, studies on environmentally relevant concentrations are essential. Zebrafish were used as a model organism to assess growth and development in larvae and examine tissue accumulation, oxidative stress, and DNA methylation in adults.
