Currently, plastic is used being without any limitations. The livestock sector is no stranger to its use. For example, artificial insemination involves the use of different plastic materials, including semen straws and insemination catheters, which increase the levels of waste in our environment. Finding a sustainable solution to avoid plastic materials is a challenge. The aim of this study was to examine different biodegradable materials as alternatives to conventional syringes used for refrigerated equine semen. The materials tested were bamboo, avocado, grass, paper, Kraft paper, wheat, and rice. Bamboo and avocado were selected to continue testing with the refrigerated semen with a lifespan extended by INRA 96; the rest of the materials did not meet the requirements necessary for preservation. Motility and movement kinetics tests were performed at 24 and 96 h of refrigeration to evaluate semen quality; relative to the control, significantly better results were displayed in regard to the total and progressive motility avocado straws. The kinetic parameters were comparable to the control for both materials and within normal ranges. After performing a microbiological control process for both straws, it was confirmed that there was no bacterial growth in either straw. We can confirm that avocado straws can be used to preserve chilled equine semen, guaranteeing seminal quality while being respectful to the environment.
目前，塑料的使用没有任何限制。畜牧业对其使用并不陌生。例如，人工授精涉及使用不同的塑料材料，包括精液吸管和授精导管，这增加了我们环境中的废物水平。寻找一种可持续的解决方案来避免使用塑料材料是一项挑战。本研究的目的是研究不同的可生物降解材料，以替代用于冷藏马精液的传统注射器。测试的材料有竹子、牛油果、草、纸、牛皮纸、小麦和大米。选择竹子和牛油果继续用INRA 96延长寿命的冷藏精液进行测试；其余材料不符合保存所需的要求。在冷藏24小时和96小时时进行活力和运动动力学测试以评估精液质量；相对于对照，牛油果吸管在总活力和渐进活力方面显示出明显更好的结果。两种材料的动力学参数与对照相当且在正常范围内。对两种吸管进行微生物控制过程后，证实两种吸管中均无细菌生长。我们可以确认，牛油果吸管可用于保存冷藏马精液，在保证精液质量的同时尊重环境。
