Research ArticleOpen accessEvery word in the titleEffect of Temperature Change and Estradiol Levels on Cattle Oocytes Developmental Competency: Comparing X-Sexed and Non-Sexed Sperm Following in vitro FertilizationMaleke Dimpho Sebopela, Masindi Lottus Mphaphathi et al.The study aimed to investigate the effects of temperature change and estradiol (E2) hormone level on In Vitro Maturation (IVM) and fertilization of cattle oocytes using X-sexed and non-sexed sperm. In experiment 1: The oocytes were incubated at various temperatures of 35.5, 36.5, 37.5, 38.5, 39.5 and 40.5°C under similar conditions with 5% CO2, in humidified air for 22 h. … …American Journal of Animal and Veterinary Sciences, Vol. 18, Issue 4 · 16 Nov 2023 · 5,319 accessesView PDFCite
InvestigationOpen accessEvery word in the titleThe Dependence of Photosynthetic Indices and the Yield of Spring Rape on Foliar Fertilization with MicrofertilizersValentina A. Gulidova, Tatyana V. Zubkova, Vladimir A. Kravchenko, Olga A. DubrovinaApplication of fertilizers is included today into the cultivation intensive technologies, as one of the basic components providing for high crop yield. Today, the minimal tillage is widely used, which significantly reduces the choice of fertilizer application method in comparison with classical fertilizers. Therefore, the competent use of the remaining methods of feeding field crops becomes very important. An innovative … …OnLine Journal of Biological Sciences, Vol. 17, Issue 4 · 16 Dec 2017 · 6,987 accessesView PDFCite
