This study evaluates the utilization of in vitro embryo production (IVEP) technology for the conservation and breeding of the Auliekol cattle breed, a primary beef breed in Kazakhstan facing population decline due to the cessation of breeding programs and the incursion of transboundary diseases. We assessed the effect of consecutive ovum pick-up (OPU) procedures on oocyte yield and embryo production in Auliekol and Aberdeen Angus cows. A total of 2232 and 3659 oocytes were aspirated from Auliekol and Aberdeen Angus donors, respectively, with significantly higher yields and embryo production observed in Aberdeen Angus cows.

- Anthrax is a major zoonotic disease concern in Kazakhstan, particularly affecting public health and agriculture, with annual outbreaks primarily in West Kazakhstan.
- A survey was conducted from January to May 2022 involving 489 participants in Baiterek province to assess community knowledge, attitudes, and practices about anthrax; it's the first of its kind in the country.
- The findings revealed significant gaps in awareness, with over 50% lacking knowledge about the disease's zoonotic nature and symptoms, though interest in livestock vaccination was high, especially among older respondents.
The reactive spark plasma sintering (R-SPS) method was compared in this work with the two-step SHS-SPS route, based on the combination of the self-propagating high-temperature synthesis (SHS) with the SPS process, for the fabrication of dense (HfMoTiTaNb)B-SiC and (HfMoTiTaZr)B-SiC ceramics. A multiphase and inhomogeneous product, containing various borides, was obtained at 2000 °C/20 min by R-SPS from transition metals, BC, and Si. In contrast, if the same precursors were first reacted by SHS and then processed by SPS under the optimized condition of 1800 °C/20 min, the desired ceramics were successfully attained.
