The role of State Forest Enterprises in the payments for Forest Environmental Services Programme in Vietnam
(Kassel University Press, 2017-12-17)
To promote pro-poor payments for environmental services, it is necessary to identify institutional options that reduce transaction costs and organisational problems associated with establishing and maintaining contracts with small-scale environmental service providers. This study examined the dual functionality of state forest enterprises (SFEs) in the implementation of the Payments for Forest Environmental Services (PFES) Program in Vietnam. We considered whether SFEs’ involvement in the programme could reduce ...
Dissertation
Production Diseases in European Organic Dairy Farms – Current Status and Identification of Drivers for Improvement by Means of a Systemic Approach
(2017-01-18)
The aims of this thesis were to determine the animal health status in organic dairy farms in Europe and to identify drivers for improving the current situation by means of a systemic approach. Prevalences of production diseases were determined in 192 herds in Germany, France, Spain, and Sweden (Paper I), and stakeholder consultations were performed to investigate potential drivers to improve animal health on the sector level (ibid.). Interactions between farm variables were assessed through impact analysis and evaluated ...

Ameliorative potential of vitamin E on the impact of dietary fumonisin B1 on reproductive performance of female rabbits
(Kassel University Press, 2017-06-26)
Fumonisin B1 (FB1), a contaminant of agricultural products, particularly maize worldwide is known to be consumed by farm animals and has been documented to cause various physiological responses in animals. A 15-week trial on the ameliorative potential of vitamin E on the negative impacts of FB_1 on reproductive performance of rabbits was conducted. Forty-nine female rabbits aged 16 to 18 weeks weighing 1.65 to 2.0 kg body weight were assigned to seven experimental feeding groups: the control group received a diet ...

The effect of feeding restriction with cassava flour on carcass composition of broilers
(Kassel University Press, 2017-12-15)
In order to promote poultry farming in resource-limited rural areas, the effects of feeding restriction with cassava flour on the carcass composition of broilers was studied. After three weeks on a restrictive diet (step 1), the broilers were re-fed during four weeks according to their physiological needs (step 2). In total, 75 four-weeks old chicks were randomly divided into three lots of 25 subjects. Lot I (control) is fed without cassava flour. The lots II and III are fed with diets containing respectively 10 and ...

Effect of pre-plant treatments of yam (Dioscorea rotundata) setts on the production of healthy seed yam, seed yam storage and consecutive ware tuber production
(Kassel University Press, 2017-12-27)
Numerous pests and diseases of yams are perpetuated from season to season through the use of infected seed material. Developing a system for generating healthy seed material would disrupt this disease cycle and reduce losses in field and storage. The use of various pre-plant treatments was evaluated in field experiments carried out at three sites in Nigeria. Yam tubers of four preferred local cultivars were cut into 100 g setts and treated with pesticide (fungicide + insecticide mixture), neem extract (1 : 5 w/v), ...

Effects of exogenous cellulase and xylanase enzyme preparations on feed intake, nutrient digestibility, growth, and economics of rearing Mongolian lambs
(Kassel University Press, 2017-03-29)
In a completely randomised design, twenty four 12-months old Mongolian breed male lambs averaging 21.6 ± 0.48 kg of body weight (BW) were used to evaluate the effects of exogenous cellulase and xylanase enzyme preparations on feed intake, digestibility of nutrients, growth and economics of rearing lambs. The lambs were randomly assigned to six treatment groups with four animals per treatment. The treatment combinations comprised: i) two enzyme preparations, i.e. cellulase vs. xylanase (ENZc, ENZx), ii) two ration ...

The determinants of the performance of dairy smallholders in Malawi
(Kassel University Press, 2017-03-23)
Milk production in Malawi is stagnating although neighbouring countries steadily increase outputs. In this paper, we explored the determinants of the performance of dairy smallholders. As indicators of on-farm performance we used annual milk yield, calving intervals, and annual dairy income. Regression models revealed that milk yield was negatively related with farmer’s age, female farmer, and household size, but positively influenced by farmers’ experience. Calving intervals were strongly associated with labour costs ...

Participatory Rural Appraisal for Diagnostic Analysis of spate irrigation systems in Raya Valley, Ethiopia
(Kassel University Press, 2017-05-12)
Spate irrigation is a complex and unique form of water management, which represent the main source of irrigation water in semi-arid river catchments. Water is diverted from seasonal rivers by using diversion structures made by stones, earth and brushwood, located within the river bed. The modernisation of spate irrigation realised in Raya Valley (northern Ethiopia) resulted in disappointing performances. One of the main reasons for this failure was the poor consideration of the characteristics of seasonal catchments ...

Evaluation of cassava leaf meal protein in fish and soybean meal-based diets for young pigs
(Kassel University Press, 2017-04-21)
The unavailability and high cost of traditional ingredients calls for more research into alternative sources for pig feeding in the South Pacific region. The effect of replacing feed protein with cassava leaf meal (CLM) protein in weaner and growing pigs’ diets was investigated in two experiments. In experiment 1, three diets in which CLM protein replaced 0, 15 and 30% of feed protein were fed each to five replicate pens of weaner pigs. Feed intake (FI), body weight gain (BWG) and feed conversion ratio (FCR) were ...

Index-based agricultural insurance products: challenges, opportunities and prospects for uptake in sub-Sahara Africa
(Kassel University Press, 2017-07-25)
Agricultural insurance products have been piloted in Sub-Saharan Africa (SSA) to address climate related risks faced by farmers. However, these products in general face low rates of adoption in SSA. Factors and challenges that may explain the low uptake of index-based insurance products in SSA are reviewed in this paper with the objective of assessing and documenting (i) the insurance products available to farmers, (ii) factors influencing farmers to purchase insurance products, (iii) challenges limiting farmers ...
