Abstract:
Oral vaccination is one of the most effective interventions for disease control in wildlife. As a result of the recent global reemergence of African swine fever and ongoing classical swine fever and animal tuberculosis, oral vaccination of Eurasian wild boar (Sus scrofa) receives increased interest. Several baits for wild boar and feral pigs have been described, but developing more stable and personalized formulations is important. This paper proposes a new bait formulation primarily composed of corn flour, piglet feed, sugar, and honey as a binder to obtain improved elasticity. The bait consists of a matrix with no protective coats, has a hemispherical shape (ø 3.4 ×1.6 cm), and displays an anise aroma and blue color. The color and aroma did not affect bait choice by wild boar, while bait coloring contributed to avoid consumption by non-target species (corvids). Baits with the new formulation were significantly more resistant to humidity and high temperatures than previous versions. Simulations suggest that baits with the new formulation are elastic enough to resist impacts from a maximum altitude of 750 m. Thus, the new bait prototype solves several problems of previous bait formulations while keeping a format that can be selectively consumed by piglets and adult wild boar.
摘要:
口服疫苗接种是野生动物疾病控制最有效的干预措施之一。由于最近全球再次出现非洲猪瘟和持续的经典猪瘟和动物结核病,欧亚野猪(Susscrofa)的口服疫苗受到越来越多的关注。已经描述了几种用于野猪和野猪的诱饵,但是开发更稳定和个性化的配方很重要。本文提出了一种主要由玉米粉组成的新诱饵配方,仔猪饲料,糖,和蜂蜜作为粘合剂,以获得改善的弹性。诱饵由没有防护涂层的基质组成,具有半球形(Φ3.4×1.6cm),并显示茴香香气和蓝色。颜色和香气不影响野猪的诱饵选择,而诱饵着色有助于避免非目标物种(corvids)的消耗。与以前的版本相比,新配方的诱饵对湿度和高温的抵抗力明显更高。模拟表明,新配方的诱饵具有足够的弹性,可以抵抗最大海拔750m的冲击。因此,新的诱饵原型解决了以前诱饵配方的几个问题,同时保持了仔猪和成年野猪可以选择性食用的形式。
