Effect of modified CEP-3 diluents with aqueous soybean extract on liquid semen quality in Ongole crossbred bull.

Background And Aim: Egg yolk (EY) is commonly used as an extracellular cryoprotectant in semen diluents but has some negative effects. Therefore, this study aimed to assess the potential of lecithin derived from plants, such as soybeans, as an alternative extracellular cryoprotectant and to characterize liquid semen quality of Ongole crossbred bulls using a modified caudal epididymis plasma-3 [CEP-3 (m)] as a base diluent and aqueous soybean extract (ASE).

Materials And Methods: A bull with progressive motility (PM) of fresh semen >70% was used.

The effect of paclobutrazol on the development of zebrafish (Danio rerio) embryos.

Paclobutrazol (PBZ), a trazole-containing fungicide, is widely used on food crops. Frequent usage of PBZ may contaminate water, but its toxicity to aquatic organisms is understudied. Although the chronic effects of PBZ exposure on reproductive, antioxidant defense, and liver metabolism systems in rockfish have been reported, the toxic effects of PBZ on aquatic embryos are unknown.
