摘要

本研究旨在探讨光周期等环境因素对墨西哥韦拉克鲁斯地区水牛卵母细胞数量的影响。通过卵泡抽吸获得卵母细胞123个,并根据形态特征进行分级。有关区域环境因素(温度、湿度和日光)的数据收集自气象站的历史数据库。与其他变量通过Person相关、单因素方差分析和线性回归分析(P0.05)进行统计学分析。卵母细胞总数和活卵量及环境变量随ITH或卵母细胞活卵量的变化而变化(P0.05)。综上所述,温度、湿度和日光均影响卵母细胞总数和活细胞数。光周期似乎是影响墨西哥韦拉克鲁斯州水牛卵母细胞数量的最重要因素。

Effect of photoperiod and other environmental factors on the oocyte populations of water buffalo (Bubalus bubalis) in Veracruz state, Mexico
The objective of this study was to investigate the effect of photoperiod and other environmental factors on the population of Water buffalo oocytes in Veracruz, Mexico. Oocytes (n=123) were obtained by follicular aspiration and graded according to morphological characteristics. Data regarding regional environmental factors (temperature, humidity, and daylight) were collected from a historic database of a metrological station. Statistical analysis was performed through Person correlation, one-way ANOVA and linear regression analysis, P<0.05 was considered significant. There was a correlation (P<0.05) between oocyte populations (total and viable) with temperature, humidity, and duration of daylight. ITH (index of temperature and humidity) and oocyte viability did not correlate (P>0.05) with other variables. Oocyte populations (total and viable) and environmental variables changed (P<0.05) during all the sampled months. Oocyte populations (total and viable) were affected (P<0.05) by temperature (r=-0.63; r=-0.57), humidity (r=0.46; r=0.39) and daylight (r=-0.86; r=-0.87), no association (P>0.05) with ITH or oocyte viability were identified. In conclusion, temperature, humidity, and daylight affected the oocyte populations (total and viable). Photoperiod seemed to be the most important factor affecting oocyte populations of water buffalos in Veracruz state, Mexico.
