摘要

土着乡村鸡(IVCs)从觅食饲料资源基地获得大部分饲料。自由漫游使ivc可以自由地表达自己的本能,从而提高它们的福利。放养也赋予了IVCs优秀的探索行为。然而,捕食者也可能是共同进化的,这就需要小农的特殊干预来减少捕食者的不利影响。本研究确定了IVCs的主要捕食者以及小农采取的规避策略。这项横断面研究包括对119名小农户的一般性访谈。脑室病(脑室病)的发病率农民后院周围的奶酪人会造成重大威胁,因为它是陆地捕食者的避难所。小农通过巡逻、看门狗、围栏、禁闭以及在极少数情况下的杀戮来躲避捕食者。在一次无意的谈话中,一个线人透露,有一些牧师能力但没有牧师头衔的人在全黑小麦上施了咒语。据报道,当鸡被喂食这种谷物时,空中捕食者变得虚弱,无法捕捉鸡。农业生态区对小农遭遇捕食者的比例和采取的躲避策略类型有显著影响。这种联系需要开发基于农业生态学的捕食者-逃避方法。然而,捕食者的躲避方法需要进一步改进,以减少鸡的反复损失。必须彻底调查与掠食者挑战相关的威胁,以提高它们的逃避策略。导致家庭家禽大量损失的另一个问题是盗窃。除了用来躲避捕食者的策略(这也适用于控制盗窃)之外,法律体系还必须组织良好,以惩罚这类不法行为。

Predation and theft: the standing threats of the scavenging chicken production system
Indigenous Village Chickens (IVCs) obtain most of their feed from a scavenging feed resource base. Free roaming makes IVCs express their instincts at will, which could enhance their welfare. Free-ranging has also endowed IVCs with excellent explorative behavior. However, predators might have also co-evolved, which necessitates special interference from smallholder farmers to reduce the adverse impact of predators. This study identified the main predators of IVCs and the evading strategies adopted by smallholder farmers. This cross-sectional study involved a general interview with 119 smallholder farmers. The prevalence of enset, Ensete ventricosum (Welw.) Cheesman, around the farmer's backyard can impose a significant threat because it shelters terrestrial predators. Smallholder farmers evade predators through patrolling, guarding dogs, fencing, confinement, and, in rare cases, killing. An unplanned conversation made with an informant revealed that men with some clerical ability but no priesthood title incantate on whole grains of black wheat. When the chicken is fed this grain, reportedly, the aerial predator becomes weak and cannot catch the chicken. The agroecological zone has a statistically significant impact on the proportions of predators encountered and the types of evading strategies adopted by smallholder farmers. This association entails the need for developing agroecology-based predator-evading methods. Predators' evading methods, however, need to be refined further to reduce the recurrent losses of chickens. The threats associated with predators' challenges must be thoroughly investigated to advance their evading strategies. Another problem that leads to the significant loss of family poultry is theft. In addition to the strategies used to avoid predators, which may also apply to controlling theft, the legal system must be well-organized to punish such misdeeds.

期刊介绍: The Journal of Biological Research – Bollettino della Società Italiana di Biologia Sperimentale is one of the oldest journals in Biology. Founded in 1925 the journal is available in Medline until 2001 and Scopus since 2014. The Journal of Biological Research – Bollettino della Società Italiana di Biologia Sperimentale is an online-only peer-reviewed journal which welcomes papers dealing with any aspect of experimental biology. Papers concerning clinical topics can be accepted only if they include experimental laboratory data. Original communications, review articles or short communications may be submitted.
