Characterisation of the lactation curve of Gyr and Sardo Negro cattle
(2023-07)
The objectives were to characterize the lactation curves (LC) of tropical Gyr and Sardo Negro (SN) cattle from Mexico for the design of breeding and management programs for these breeds. A total of 3561 records of 504 lactations and 3927 records of 449 lactations were used for Gyr and SN, respectively. Three lactation lengths (LL) were evaluated, namely 240 (240d), 270 (270d), and 300 (300d) days, with five non-linear models (NLM): Wood, Wiltmink, Cobby, Brody, and Sikka. Milk production was obtained at the beginning ...

Intervention options for small-scale family poultry development in south-eastern Madagascar: an expert survey
(2023-03-14)
The diets of resource-poor farmers in the Atsimo Atsinanana (AA) region of south-eastern Madagascar have limited diversity and are low in animal protein. Although poultry farming is widespread, productivity is low, and consumption of eggs is uncommon. To enable effective development interventions targeting poultry value chains, this study pursues two goals: (i) to describe current challenges in small-scale poultry rearing and egg consumption in AA, and (ii) to explore viable options for promoting poultry production. ...

Identification of socio-economic characteristics and farmers’ practices affecting rice (Oryza spp.) yields in Benin (West Africa)
(2022-12-28)
Rice (Oryza spp.) is one of the major staple foods in Benin. Benin has increased rice production through the expansion of cultivation area rather than increasing rice yields. To better understand the factors affecting rice yields, a thorough understanding of the current rice production system characteristics and constraints is required. The present study identifies socio-economic characteristics and farmers’ practices affecting rice yields and suggests improved cultivation practices in the sector. Data were collected ...

Income and price elasticities of animal food demand and welfare in Indonesian urban: an application of the LA-AIDS
(2022-12-30)
Protein consumption can be a measure of the welfare of society. Developed countries consume more protein than developing countries. This study analyzes the effect of rising prices and income on demand and welfare in urban Indonesia. The research data use the 2018 Household National Socio-Economic Survey (Susenas) data in household consumption and expenditure data collected by the Central Statistics Agency (BPS). The number of samples is 133,873 households. The demand systems approach uses the Almost Ideal Demand ...

Exploring inclusiveness of vulnerable and marginalized people in the cassava value chain in the Lake Region, Kenya
(2023-03-21)
Vulnerable and marginalised groups (VMGs) who comprise widows, orphans, people living with disability and HIV, have not been given sufficient attention in agriculture in sub-Saharan Africa (SSA) by policy makers, development partners, research, and extension, yet they comprise nearly one-quarter of all smallholder farmers. This study explored inclusion of VMGs in cassava value chain in the Lake Region of Kenya. Formal survey, focus group discussions (FGD), and key informant interviews (KIIs) were used to collect data ...

Sustainable Eating Futures: A Case Study in Saudi Arabia
(2022-10-25)
Food systems are central to human societies. Developing sustainable, nutritious, and healthy food systems will be crucial to accomplishing sustainable development goals. The multifarious politics underlying food production, distributions as well as consumption are often ignored. The present paper analyses different factors affecting food consumption in the local population of Saudi Arabia and relates them to the supply chain. Different futuristic scenarios are discussed to develop sustainable food consumption practices ...

Economic evaluation of biological nitrogen fixation in flooded rice cultivation in subtropical lowlands
(2023-06-13)
This study aimed to assess the economic viability of biological nitrogen fixation in flood rice cultivation in subtropical lowlands. A field experiment of seven treatments was carried out during the cropping seasons 2015/16, 2017/18, 2018/19 and 2019/20 at the Lowland Experimental Station of Embrapa, in Pelotas, RS, Brazil. The evaluated treatments were: (1) negative control (without N and inoculant); (2) positive control with recommended N-fertilization (120 kg N ha-¹, without inoculant) (standard recommendation); ...

Effect of Fermentation on the bioactive compound of cocoa Beans: a systematic review and meta-analysis approach
(2023-05-30)
Several studies have found the effect of cocoa bean fermentation on bioactive compounds through various fermentation characteristics; however, none of these studies adopted the meta-analysis approach. The effect of cocoa bean fermentation on six bioactive compounds: epicatechin, catechin, total phenolic content (TPC), anthocyanins, theobromine, and caffeine were systematically reviewed. This study aims to determine which variables that can affect the loss of bioactive compounds during fermentation so that their ...

Identification of fungal pathogens causing postharvest rot of bulb onions (Allium cepa L.) in selected major growing regions of Kenya
(2023-06-27)
Rot is a major cause of bulb onion losses in Kenya, accounting for about 14 % of total postharvest losses. In Kenya, the fungi associated with bulb onion postharvest rot of onion postharvest rots are not well known. Therefore, this study aimed at identifying the fungal pathogens contributing to bulb onion postharvest rot in major growing regions of Kenya. Bulb onion samples were collected from seven major markets and isolates were obtained by cutting 3 mm tissue segments from the edges of rotten lesions. These were ...

Measuring the economic performance of smallholder organic maize farms; Implications for food safety and security
(2023-05-31)
The use of chemical inputs in conventional agriculture is associated with some health and environmental issues. This led to a call for more sustainable and environmentally friendly agriculture with no health issues. However, there is low participation in organic farming in Nigeria, which could be linked to less knowledge about its profitability. The study investigated smallholder organic maize farming profitability in Northern Nigeria. We employed descriptive statistics, profitability analysis, and a multiple regression ...
