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 ...

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’ ...

Choice of savings instruments among rural women maize farmers: evidence from Uganda
(2021-05-25)
Households in developing countries employ a wide range of mechanisms for making cash and in-kind (goods and services) savings which are either formal or informal. Yet, literature on how choices about appropriate savings instruments are made remains scanty. We examine the patterns and choice of these saving instruments using household data from women farmers in eastern Uganda. In particular, the paper focuses on the choice between formal cash saving instruments like commercial banks, village savings and loans associations ...

Nutrient digestibility, nitrogen balance and rumen fermentation parameters of West African dwarf goats offered treated maize stover supplemented with Gmelina arborea
(2021-05-20)
A large portion of agricultural crop residues are potential feed resources for ruminants in the tropics. This study therefore, investigated the intake, nutrient digestibility, nitrogen utilisation and rumen fermentation parameters of West African dwarf goats (WAD) fed treated and untreated maize stover supplemented with Gmelina arborea. Twenty male WAD goats (11.50 ± 0.45 kg body weight) were randomly allotted into four treatments with five animals each. Untreated maize stover (MS), urea treated maize stover (UT), ...

Growth performance and immunological response of African Catfish (Clarias gariepinus) juveniles reared in biofloc system
(2021-06-08)
This study was conducted to examine the growth and immune performance of catfish (Clarias gariepinus) juveniles cultured in a biofloc fish farming system. To achieve this, 900 C. gariepinus juveniles (9.0 ± 0.23 g) were cultured in an intensive zero water exchange biofloc system for 72 days in 9 separate tanks (2 m3 each) aerated by an air blower, after which growth assessment of fish was conducted. The trial consisted of three treatments in triplicates, a control without carbon source addition, and two biofloc ...

A review of the literature on gender and chemical fertiliser use in maize production in sub-Saharan Africa
(2021-05-25)
Are there differences in men’s and women’s access to and use of fertiliser in sub-Saharan Africa? This article explores the issue through a systematic review of the extant literature on gender and fertiliser use in maize production. The findings show that indeed a gender gap in the use of fertiliser exists. More than a decade after the World Bank identified a gender gap in fertiliser use, there are no systematic national or global data sets comparing fertiliser use by gender. While farm input subsidies can improve ...

Incorporation of dried goat rumen contents in layer diets improves egg yolk colour and acceptability of eggs
(2021-06-07)
The use of dried goat rumen content (DGRC) as a partial replacement for fish meal in layer diets was investigated. A total of 90 H&N Brown Nick layer chickens were offered diets in which DGRC were incorporated at 0, 5 and 10% levels. Iso-caloric and nitrogenous diets were formulated to meet the recommended nutritional requirements for laying hens. Experimental birds were assigned to 9 cages (10 birds/cage) and experimental diets offered in a completely randomized design (CRD) with three replications. Data was collected ...
