Abstract
Intensive semen collection often leads to "kidney yang deficiency" in male yaks, with symptoms like lethargy and poor semen quality. Our modified "Yijing Fang" was tested. Eight 3 - 6-year-old male yaks with this condition were split into treatment and negative control groups; four healthy yaks were a blank control. The treated yaks got the formula in feed for 5 days, then a 20-day break, repeating 3 times over 65 days. Semen was collected, and cAMP, cGMP, T/E2 levels, and mitochondrial apoptosis factors were analyzed. Results showed the formula boosted semen quality. cAMP and testosterone rose (p < 0.01), cGMP and estradiol fell (p < 0.01), cAMP/cGMP and T/E2 ratios climbed (p < 0.01). Bcl-2 upregulated, Bax, Cyt-C, and Caspase-3 downregulated (p < 0.01). In conclusion, the modified "Yijing Fang" is effective for yak reproduction, enhancing hormone secretion and reducing sperm apoptosis. Long-term studies are needed.
期刊介绍:
Animal Reproduction (AR) publishes original scientific papers and invited literature reviews, in the form of Basic Research, Biotechnology, Applied Research and Review Articles, with the goal of contributing to a better understanding of phenomena related to animal reproduction.
The scope of the journal applies to students, researchers and practitioners in the fields of veterinary, biology and animal science, also being of interest to practitioners of human medicine. Animal Reproduction Journal is the official organ of the Brazilian College of Animal Reproduction in Brazil.
