Application of non-linear models in description of growth of dual purpose FUNAAB Alpha chickens
(2021-08-03)
Growth is explained mathematically by models that have parameters with biological interpretations. This study was conducted to compare five non-linear growth models (Gompertz, Brody, Logistics, Von Bertalanffy and Negative exponential) in order to describe growth in the three genotypes (normal feather, naked neck and frizzle feather) of the dual purpose FUNAAB Alpha chickens (n=332). Doesn’t Use Derivative iterative method of nonlinear procedure in SAS was used to estimate the model parameters. Computational difficultly, ...

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 ...

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), ...

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 ...

Potassium iodide influence on iodine-leaf concentration and growth of amaranth (Amaranthus cruentus L.)
(2021-05-25)
Low iodine content in soils is a common feature in lowland and in mountainous regions far from oceans. The diets of the people living in these regions are often deficient in dietary iodine, resulting in chronic iodine deficiency syndrome, goiter, hearing loss and other debilitating diseases. A field experiment was conducted at the Teaching and Research Farm, University of Ilorin, Nigeria during the 2017 and 2018 cropping seasons, to evaluate the response of amaranths to iodine enrichment using an agronomic approach. ...

Early planting and relay cropping: pathways to cope with heat and drought?
(2021-05-05)
Maize (Zea mays) is an important food and cash crop of uplands in Southeast Asia, where it is often prone to drought and heat stress associated with climate change. This study aimed at assessing the effect of heat and drought on maize performance, testing coping strategies under such weather extremes, and understanding associated mechanisms. The experiment was carried out during 2018 in Thailand, using a split-plot design with three replications. Treatments were: July-planted maize sole cropping (control), July-planted ...

Nutritional, antioxidant properties and polyphenol content of quinoa (Chenopodium quinoa Willd.) cultivated in Iran
(2021-05-25)
The quinoa is pseudocereal plant that has nutritional value. Recently, It was cultivated in iran because of water crisis. This study aimed to assess the physicochemical and antioxidant properties of quinoa cultivated in Iran for the first time. The macronutrients and energetic value, polyphenol, total phenol content and DPHH of quinoa were measured. Some B group vitamin, the free fatty acid profile was assessed by HPLC and GC-mass separately. The trace elements were also evaluated by ICP. The amounts of dry matter, ...

An investigation of the aspects affecting non-Muslim customers’ purchase intention of halal food products in Jakarta, Indonesia
(2021-05-25)
The international trade market of halal food products is huge and has become a fast-growing segment. People that consume food and beverage will also consider if it is good for health, well-being, nutrition, and physical fitness. Nowadays, halal products are requested by Muslim and non-Muslim customers due to safety and quality concern. Even though several studies have been conducted for Muslim customers, but there is a lack of data by foregoing studies which exploring non-Muslim customers about their intention in ...

Nutrient and oil profile of Escamol, an edible larva of ants (Liometopum apiculatum Mayr)
(2021-05-25)
The objective of this study was to evaluate proximal chemical analysis, oil and fatty acids in escamol dehydrated and butter-fried that are commercially available in Mexico. In order to measure the escamol and oil quality, a chemical analysis were performed. The identification fatty acids was by refractive index. The proximal chemical analysis results in escamol fresh and deshydrated indicated that moisture (56.00-1.89 %), protein (15.30-34.78 %), lipids (20.05-45.57 %), ash (1.91-4.35 %) and carbohydrates (6.73-13.41 ...

Trust and the clean food imaginaries: an analysis of a short food supply chain from Romania
(2021-05-25)
As concerns about food safety and environmental issues gain more attention in the public eye, organic labels are growing in popularity, being presented as the solution for a more sustainable and conscious food system. Yet, organic certificates did not manage to actively change the food system but merely created a niche to be exploited, thus many of the environmental-friendly practices being co-opted by corporations without addressing the larger issues of concern. This paper looks at how small producers, who are ...
