Abstract

The objective was to evaluate the effect of the season on the sexual behavior patterns adopted by Morada Nova sheep in the Brazilian semiarid region. A total of 55 and 59 female sheep were used in the rainy and dry seasons, respectively, attended by four males of the same breed in rotation. The females identified in oestrus were released in a pasture, together with the breeder of the day for each season, and aspects of sexual behavior were measured for an uninterrupted period of 11 hours/day. Assuming a negative binomial distribution, the behavioral frequencies were subjected to deviation analysis and compared using the chi-square. Heading in the male was observed more frequently during the rainy season (0.12) and shifts with higher temperatures; the turn of the head in relation to the man was observed more frequently during the dry season (2.49). The interactions between seasons and shifts significantly affected the following behaviors: sniffing the male, sniffing the male's urogenital region, wagging the tail, lifting the tail, and urinating. Behavioral variables were influenced by the season. Morada Nova sheep reduce their water intake and grazing time to engage more efficiently in reproductive activities, thus demonstrating an ability to adapt to the Caatinga.

在半干旱的赤道环境中，莫拉达诺瓦母羊的性行为在一年中的季节变化

目的是评价季节对巴西半干旱区Morada Nova羊性行为模式的影响。在雨季和旱季分别使用55只和59只母羊，由4只同一品种的公羊轮流照料。在发情期确定的雌性被释放到牧场，与每个季节当天的饲养员一起，在每天11小时的不间断期间测量性行为的各个方面。假设为负二项分布，行为频率进行偏差分析，并使用卡方进行比较。雄蝶在雨季(0.12)和气温升高时的抽穗率较高;与男性相关的头部转动在旱季更为频繁(2.49)。季节和变化的相互作用显著地影响了它们的以下行为:嗅闻雄性、嗅闻雄性的泌尿生殖区、摇尾巴、抬起尾巴和小便。行为变量受季节影响。Morada Nova羊减少饮水量和放牧时间，以便更有效地进行繁殖活动，从而显示出适应Caatinga的能力。

Our journal is published quarterly, where the published articles are inserted into areas of animal behaviour, animal biometeorology, animal welfare, and ambience: farm animals (mammals, birds, fish, and bees), wildlife (mammals, birds, fish, reptiles, and amphibians), pets, animals in zoos and invertebrate animals. The publication is exclusively digital and articles are freely available to the international community. Manuscript submission implies that the data are unpublished and have not been submitted for publication in other journals. JABB publishes original articles in the form of Original Articles, Short Communications, and Reviews. Original Articles arising from research work should be well grounded in theory and execution should follow the scientific methodology and justification for its objectives; Short Communications should provide sufficient results for a publication in accordance with the Research Article; Reviews should involve the relevant scientific literature on the subject. JABB publishes articles in English only. All articles should be written strictly adopting all the rules of spelling and grammar.
