Genotypic differences in body weight and physiological response of local and exotic turkeys challenged with Salmonella typhimurium
(2021-11-02)
To better understand susceptibility and/ or tolerance of locally adapted turkey to salmonellosis, we compared bodyweight, antibody titres and physiological traits based on genotype and sex of salmonella-infected turkeys. Three hundred poults from two genotypes (160 local and 140 exotic turkeys) were raised for twenty weeks. Bodyweight (BW), rectal temperature (RT), pulse rate (PR) and respiratory rate (RR) were measured weekly. Blood samples were collected from each turkey before and after inoculations at week 8 and ...

Drivers of adaptation to climate change in vulnerable farming communities: a micro analysis of rice farmers in Ndop, Cameroon
(2021-11-04)
Farmers in developing economies often struggle to adapt to climate change and their decisions to adapt usually hinges on perception and prevailing socio-economic factors. This study examines factors controlling farmers’ decision to adapt to climate change and evaluate the impact of such decisions on farm output. Using primary data from 138 rice farming households in Ndop-Cameroon, we employ the probit model with endogenous switching regression to investigate the impact of the farmers’ adaptation decisions on output. ...

A comparative cost-benefit analysis between fairtrade certified and non-certified cocoa production in the South-West region of Cameroon
(2021-12-31)
In order to promote cocoa agroforestry by encouraging cocoa farmers to integrate fruit trees inside their cocoa orchards, cocoa certification was initially launched since 2012 in Cameroon. Nowadays, cocoa certification is adopted by a few farmers and makes up only 3% of the national cocoa production. Using the most predominant Fairtrade certification in the South-West region, this study compared certified and non-certified cocoa production via a cost-benefit analysis. The results indicated that, in spite of its ...

Effect of different mechanical seed scarification methods on germination and emergence dynamics of baobab (Adansonia digitata L.)
(2021-10-28)
The African baobab (Adansonia digitata L.) is a multipurpose fruit-producing tree that is indigenous to the African savannahs. Commercial interest in the species has grown in recent years. The major obstacle of seed-based propagation of baobab is its inherent seed dormancy. Therefore, in this study the effects of different mechanical seed scarification methods on seed germination parameters and seedling development of A. digitata were tested. The results show that mechanical scarification had a significant effect on ...

Scaling up community-based goat breeding programmes via multi-stakeholder collaboration
(2020-05-01)
Community-based livestock breeding programmes (CBBPs) have emerged as a potential approach to implement sustainable livestock breeding in smallholder systems. In Malawi and Uganda, goat CBBPs were introduced to improve production and productivity of indigenous goats through selective breeding. Scaling up CBBPs have recently received support due to evidence-based results from current implementation and results of CBBPs implemented in other regions of the world. This paper explores strategies for scaling up goat CBBPs ...

Mixed method survey of vegetable farming and rural farmers’ livelihood in Enugu State, Nigeria
(2021-12-07)
Studies on the role of agriculture on the improvement of livelihood of farmers have primarily focused on staple crops. Increased awareness on the importance of vegetables in urban and rural areas in Nigeria has led to a rise in demand of vegetables. In both rural and urban communities, smallholder farmers are responding to this demand by increasing vegetable production and thereby creating economic opportunity for themselves. The purpose of this paper is to assess the role of vegetable farming on rural farmers’ ...

Forage biomass availability, species diversity and seasonal variation in grazing behaviour of cattle in the outskirts of Ouagadougou
(2020-10-14)
In order to determine the exploitation of grazing areas in the outskirts of Ouagadougou by cattle herds, the grazing behaviour of cows was monitored in five villages in these during three distinct seasons, namely wet, cool dry and hot dry season. A vegetation study including a census of the woody and herbaceous stratum of grazing areas allowed for an assessment of the pasture biomass availability during the wet season. Results of the monitoring of cattle herds showed that the land type grazed by cattle in the outskirts ...

Determination of fat, salt and sodium contents of selected fast food items available for sale in Colombo city, Sri Lanka: An approach to colour coding of fast foods
(2021-11-29)
Fast food has become a popular trend among Sri Lankan consumers. However, the nutritional facts of these food items that aid consumer awareness are scantly found in Sri Lanka. This study aimed to examine fat, salt and sodium contents of selected fast food types sold in Colombo city. A questionnaire-based survey was conducted to identify the fast food consumption patterns of the target population. Fat, salt and sodium contents of highly preferred fast food types selected based on the survey, namely; Chinese fish roll ...

Using Moringa Oleifera Seed Cake and Compost as Organic Soil Amendments for Sustainable Agriculture in Valencia Orange Orchard
(2021-09-24)
This work was conducted during two consecutive seasons of 2016/2017 and 2017/2018 at the Experimental Research Station of National Research Centre at Nubaria, El Behiera governorate, Egypt. Twelve year old Valencia orange trees (Citrus sinensis L. Osbeck) budded on Volkamer lemon rootstock, grown in sandy soil under drip irrigation system as plant materials to study the effect of six organic soil amendment treatments on soil hydrophysical properties, soil water retention, soil water movement, plant nutrient contents, ...

Farmers' perceptions on climate change and adaptation strategies in Yendi Municipality, Ghana
(2021-11-29)
It is common to hear and read about climate change in literature, media and interpersonal discussions among farmers and environmental groups. Farmers understanding of climate change differ in the midst of these discussions because of individual experiences and perceptions after many years of farming. The rainfall is declining and the temperature is rising are the common perceptions farmers hold on climate change which they see as adversely affecting agriculture. In moments of such adversity, farmers think about what ...
