Good feed management in captivity is essential to animal survival and well-being. For snakes, most studies focus on the frequency of prey consumption and the types of prey that constitute their diets in the wild. Conversely, there is a notable scarcity of studies regarding their dietary habits in captivity. The prevailing trend involves feeding nearly all snake species exclusively with mice, barring the exceptions found in ophiophagic species. Considering that Bothrops species consume different diets in young and adults in the wild, we use B. jararacussu as a model to introduce other prey items in captivity. We use a generalized linear model (GLM) to understand if native and exotic anurans can be alternative items in the captivity diet of young and adult individuals. Our glm showed that snakes fed on bullfrog had less weight gain and consequently less growth than those provided with other diet groups. Our experiments indicated that native anurans could be an interesting food alternative to B. jararacussu and other Bothrops species with an ontogenetic diet in captivity.
圈养环境下良好的饲料管理对动物的生存和健康至关重要。对于蛇类而言，大多数研究聚焦于野外猎物的摄食频率以及构成其饮食的猎物种类。相反，关于它们在圈养环境下的饮食习惯的研究明显匮乏。普遍的做法是，几乎所有蛇类物种都只喂食小鼠，食蛇性物种除外。鉴于在野外，矛头蝮属物种在幼体和成体阶段的饮食不同，我们以巴西矛头蝮作为模型，在圈养环境中引入其他猎物。我们使用广义线性模型（GLM）来了解本地和外来蛙类是否可以作为幼体和成体圈养饮食中的替代食物。我们的广义线性模型显示，以牛蛙为食的蛇比其他饮食组的蛇体重增加更少，因此生长也更缓慢。我们的实验表明，本地蛙类对于巴西矛头蝮和其他在圈养环境中有个体发育饮食的矛头蝮属物种来说，可能是一种有趣的食物替代品。
