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 ...

Reinventing the academic conference: how delegates design productive cities
(Department of Organic Food Quality and Food Culture at the University of Kassel, Germany and Federation of German Scientists (VDW), 2015-05-20)
During the 6th International Sustainable Food Planning Conference, the so-called Design LABs partly replaced the regular parallel sessions. The reason for this change was twofold. On the one hand it aims to break through an endless series of parallel presentations, and on the other hand the LAB’s aim was to produce innovative design solutions for increasing the amount of food production in the city. This article describes this experiment to enhance the delivery of urban design concepts, which could substantially ...

Recycling urban waste as possible use for rooftop vegetable garden
(Department of Organic Food Quality and Food Culture at the University of Kassel, Germany and Federation of German Scientists (VDW), 2015-05-20)
Urban authorities in Europe are confronted with increasing demands by urban dwellers for allotment gardens, but vacant urban soil tends to be scarce and/or polluted by past industrial activities. A possible solution for local authorities could therefore be to promote rooftop gardening. However little technical information exists on certain forms of rooftop urban agriculture, called Z-Farming. In 2012, a pilot experiment was run in Paris (France). Simple and cheap systems of rooftop gardening were tested on a rooftop ...

Integrating top down policies and bottom up practices in Urban and Periurban Agriculture: an Italian dilemma
(Department of Organic Food Quality and Food Culture at the University of Kassel, Germany and Federation of German Scientists (VDW), 2015-05-20)
The paper deals with some relevant and contradictory aspects of urban and peri-urban agriculture in Italy: the traditional exclusion of agricultural areas from the goals of territorial planning; the separation between top-down policies and bottom-up practices; the lack of agricultural policies at local scale. In the first part the paper summarises the weak relation between urban planning and agriculture, showing how in Italy this gap has been only partially overcome by new laws and plans. Moreover the paper focuses ...
