Performance of pacu (Colossoma macropomum) fed varying dietary inclusion levels of fish visceral and duckweed (Lemna minor) as replacement for fish and soybean meals
(2024-01-23)
The performance of Colossoma macropomum subjected to a six-month feeding trial using duckweed (Lemna minor) and fish visceral as partial replacements for soybean meal and fishmeal respectively was evaluated in this study. A total of one thousand five hundred (1500) nearly same sizes (average size 45 g) juveniles of C. macropomum were sourced from the nearby research man-made lake and subjected to proper acclimatisation for two weeks prior to the commencement of the feeding trial. One hundred (100) juveniles per ...

Effect of different diets containing varying inclusion levels of Moringa oleifera leaf meal on growth, mineral composition and meat quality of the edible land snails Archachatina marginata and Achatina fulica
(2024-02-25)
This study examined the effect of different dietary inclusion levels of Moringa oleifera leaf meal on growth, haemolymph mineral composition and meat quality of Archachatina marginata and Achatina fulica. A total of one hundred and forty four (144) juvenile snails of A. marginata= 72 and A. fulica= 72, were used for the study. Eighteen (18) snails of each species were subjected to four dietary treatments (0%, 10%, 15% and 20%) of M. oleifera leaf meal in three replicates of six (6) snails per replicate over a period ...

Cost and return analysis of organic and conventional farming systems in the Ganga River Basin, India
(2024-02-26)
Conventional farming (CF) has significantly increased the aggregate supply of food grains and ensured food security for the growing population in India. However, it proved environmentally unsustainable due to its higher reliance on chemical inputs. Organic farming (OF) becomes an alternative approach that ensures the sustainability of the agricultural system. But, the transition from CF to OF can be a lengthy process, and farmers may experience income loss during its course. Farmers will switch only when they are ...

Sustainable management practices and soil quality in strawberry cultivation in Norte de Santander, Colombia
(2024)
In Pamplona, Norte de Santander, strawberry (Fragaria x ananassa Duch) producers face a dual challenge: ensuring the safety of their products and conserving natural resources. Nine farms belonging to the Association of Rural Women (ASMUR) were assessed, representing approximately 20% of the total affiliated production units within the association. The level of implementation of Good Agricultural Practices (GAP) was analysed in accordance with the 2020 Resolution of the Colombian Agricultural Institute (ICA), alongside ...

Price dispersion and domestic banana market response in the Philippines
(2024)
This study investigated the vertical price transmission of banana in the domestic market of the Philippines. Banana, as one of the governments’ priority crops under the Department of Agriculture’s ‘High-value Crops Development Program’, has given priority to sustainability and global competitiveness. However, the domestic banana market consists of several marketing channels. Such complex characteristics of marketing channels can negatively affect market efficiency. In addition to such issues within a banana market, ...

Effect of substituting concentrate mix with Cajanus cajan leaf on growth performance traits and carcass components of yearling rams and its potential in mitigating methane production
(2024-07-07)
The main challenges in ruminant production are to reduce feeding costs and to improve product quality while minimising environmental impact. The use of unconventional feedstuffs may contribute to decrease feeding costs and environmental impact. A study was conducted to investigate the supplementation effect of Cajanus cajan leaves (CCL) on the growth performance and carcass characteristics of yearling rams and its association with methane (CH₄) reduction in vitro. Thirty yearling rams with an initial body weight of ...

Investigating the effects of dietary supplementation with Moringa leaf powder and vitamin C in aflatoxin B1-exposed broilers
(2024-07-15)
This study investigates the use of Moringa Leaf Powder (MLP) and Vitamin C in the diets of broiler chickens exposed to Aflatoxin B1 (AFB1) to enhance performance and health. Two hundred one-day old Cobb 500 broiler breed chicks were divided into four diet groups: CON (no AFB1, no MLP), AFB (0.2 mg AFB1 per kg of feed), AFV (0.2 mg AFB1 with 200 mg vitamin C), and AFM (0.2 mg AFB1 with 500 mg MLP). Supplementation with MLP and vitamin C led to improved broiler performance, with AFM and AFV groups exhibiting higher ...

Diffusion of Material Flow Cost Accounting and its Contribution to Sustainable Development
(2022)
This thesis aims to analyze how further take-up of Material Flow Cost Accounting (MFCA) in practice can be encouraged to support sustainable development. To achieve the aim of the thesis, three studies on MFCA are conducted at multiple levels. The first study provides a better understanding of MFCA application at the corporate level in developing countries, which are characterized by rapid structure transformation leading to serious environmental problems. The second study considers the contextual and transformational ...

Assessment of the variation of marbling and intramuscular fat content of beef, and validation of possible factors to increase sensory beef quality
(2021-11)
This thesis focuses on the intramuscular fat content (IMF) or the marbling of beef as main parameters of sensory beef quality. The aim is to identify the high variability of these traits and to verify possible influences such as genetics, age, gender and feeding strategies to increase marbling.
The first part of this research focuses on the variation of quality traits within a genetically homogeneous line of an endangered German beef cattle breed “Rotes Höhenvieh” (RHV). The intramuscular fat content of beef samples ...

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, ...
