Autonomous field robots are a promising technology for solving several problems in agriculture, as they are electrical driven, can control weeds single-plant based mechanically or with microdoses of pesticides and exert less ground pressure on the field. Whether such robots will be applied on a large scale in German agriculture depends on various parameters. Therefore, the factors influencing the behavioural intention of farmers with respect to their future adoption of autonomous field robots were investigated. The analysis applies a structural equation model based on an extended version of the Unified Theory of Acceptance and Use of Technology. The dataset, collected in 2019, consists of 500 German farmers. The results reveal significantly positive effects of farmers’ expected performance, social influence and trust as well as significantly negative effects of farmers’ effort expectancy and anxiety on the behavioural intention to use autonomous field robots. Additionally, moderating effects of age on the relationship of individual constructs to the behavioural intent to use robots could be confirmed. The results provide important information for various stakeholders. Robot suppliers should better inform farmers about the performance of their products, for instance by involving farmers in the development process of the robots. The ecological benefits attributed to field robots could meet public expectations and should be better communicated to address farmers’ social influence on the behavioural intention to use the robots. Policymakers could try to create better framework conditions, for example by establishing a stable legal situation for autonomous systems or promote its use.

The aim of the present study was to compare the lipid profile in oocytes of indicus and 1/2 indicus × taurus cows with high and low antral follicle count (AFC)/oocyte yields. After an OPU procedure (D0), antral follicles ≥3 mm were counted by ultrasonography (D4, 19, 34, 49, 64), and cows were assigned to groups with either high AFC (≥30 follicles; indicus, NH group; 1/2 indicus × taurus, AH group) or low AFC (≤15 antral follicles; indicus, NL group; 1/2 indicus × taurus, AL group). The lipid profiles of the oocytes were determined by MALDI‐MS. For GI, GII and GIII oocytes, the indicus samples tend to cluster separately from the 1/2 indicus × taurus samples. The lipid species [PC (P‐38:5) + H]+ and/or [PC (P‐36:2) + Na]+, [PC (38:2) + H]+, [PC (38:5) + Na]+ and [TAG (60:8) + NH4]+ were more abundant in indicus (NH and NL groups) than 1/2 indicus × taurus. The higher lipid content in the indicus oocytes likely reflects differences in the rate of lipid metabolism and may contribute to oocyte competence and embryo development. 相似文献

研究和探讨了虾加工副产物的酶解产物（Enzymatic Hydrolysis Production,EHP）对蛋鸡产蛋率和蛋品质的影响。以虾加工副产物为原料,应用复合生物酶酶解技术制备EHP,选择产蛋率在80%以上的300日龄笼养褐壳蛋鸡288只,随机分成3组,在基础日粮中分别添加0、1.5g/100g、3g/100g虾加工副产物EHP,并替代相应重量的鱼粉,试验期为60天。EHP,可显著提高鸡蛋的哈夫单位（P〈0.05）,试验组蛋鸡产蛋率平均提高3.14%,料蛋比相应低于对照组。表明虾加工副产物EHP可显著提高产蛋高峰期过后处于衰减期的鸡蛋的哈夫单位及产蛋率。 相似文献

The concept of compliance involves the consistency and accuracy with which a client follows the regimen recommended by the veterinarian or other veterinary health care team member. Contrary to common belief, most compliance failures are not the direct result of a client's unwillingness to comply. This article will help the reader better appreciate the critical importance of effective communication by the entire veterinary health care team in achieving compliance. Success is predicated on an alliance between the practice team and the client. Certain paradigms surrounding compliance in veterinary practice are discussed, and the positive outcomes of compliance, including optimal patient care, exceptional client service, employee career growth, and economic ramifications, are explored. 相似文献
