Determinants of resource use and use efficiency in urban and peri-urban dairy, beef cattle and pig production units in Ouagadougou, Burkina Faso (West Africa)
(2019)
The (peri-) urban demand for food of animal origin is increasing in sub-Saharan Africa as a result of the rapidly growing population and urbanisation. Livestock production in the vicinity of West African cities is well established but currently undergoes changes triggered by key transforming factors such as access to resources, production management related to famers' knowledge or know-how, increasing demand for livestock and/or animal products, policies and the legal framework in which livestock production systems ...

Dependency and economic benefits of use of wild food plants use among tribal communities in Malai Madeshawara Hills wildlife sanctuary, Southern India
(2021-01-31)
Wild food plant resources and their indigenous knowledge of use, are in danger of being lost in areas where rapid environmental and cultural transformations have led to changes in eating habits and practices. The study assesses the dependency and economic value of wild food plant use among forest-dwelling communities. Community perceptions are used to assess the use patterns and interrelations of human well-being. The data is collected through a combination of semi-structured interviews, household questionnaire survey, ...

Effects of salicylic acid, putrescine and moring leaf extract application on storability, quality attributes and bioactive compounds of plum cv. 'Golden Japan'
(2020-07-30)
Background: Plum fruits constitute a good source of natural antioxidant substances. Particularly, plums contain large amounts of phenolic compounds and flavonoids that have natural antioxidant activity which is useful to human health. The study aimed to evaluate the effects of foliar sprays with salicylic acid (SA), putrescine (PUT) and moringa leaf extract (MLE) on the fruit quality attributes and bioactive compounds of 'Golden Japan' plums under cold storage conditions. Plum trees were sprayed twice; at fruit set ...

Evaluation of breeding strategies for polledness in dairy cattle using a newly developed simulation framework for quantitative and Mendelian traits
(2016-06-29)
Background: Intensified selection of polled individuals has recently gained importance in predominantly horned dairy cattle breeds as an alternative to routine dehorning. The status quo of the current polled breeding pool of genetically-closely related artificial insemination sires with lower breeding values for performance traits raises questions regarding the effects of intensified selection based on this founder pool.
Methods: We developed a stochastic simulation framework that combines the stochastic simulation ...

The impact of irrigation distribution uniformity and mulching soil on vegetative growth and yield of sweet fennel and squash plants
(Section Specialized Partnerships in Sustainable Food Systems and Food Sovereignty at the University of Kassel, Germany and Federation of German Scientists (VDW), 2020-03-31)
Water shortage under climate change impacts performed the driving forces to enhance the agricultural practices to maximize the food production. Improve the distribution of irrigation water with mulching soil to satisfy the plants needs and provide optimum conditions for production consider the main objective of the current study. Two experiments of the study were conducted out at Central Laboratory for Agriculture Climate (CLAC), Agriculture Research Center, Egypt during winter and spring seasons of 2016/2017 and ...

Was steht dem Wissenstransfer zur Tiergesundheit in der landwirtschaftlichen Nutztierhaltung entgegen?
(2021-09)
Produktionskrankheiten sind (auch in der ökologischen) Nutztierhaltung weit verbreitet und werden in der Gesellschaft zunehmend als negativer externer Effekt wahrgenommen. Sie führen zum Einsatz von Antibiotika, sind Ausdruck eines beeinträchtigten Tierwohls und verursachen den landwirtschaftlichen Betrieben Ausfallkosten. Obwohl zu den Ursachen und der Vorbeugung viel geforscht wurde sind Produktionskrankheiten weit verbreitet. Ziel der vorliegenden Arbeit war es, den mit dem Begriff Wissenstransfer beschriebenen ...

Laying hen welfare -The prevention of feather pecking and keel bone damage
(2019-05)
Feather pecking (FP) and keel bone damage (KBD) are important animal welfare problems in laying hen housing, in both organic and conventional systems.
This PhD project aimed (1) to give an overview over results from scientific studies regarding factors with preventive effects on FP, and on the extent practice recommendations are based on this scientific evidence; (2) to identify further influencing factors on FP and to test the significance of the extent of compliance with recommendations; and finally (3) to discover ...
