The women constitute almost half of the workforce engaged in agriculture. The rural women participate in a broad range of agricultural activities such as production, processing preservation and utilization of food. They play a key role in the entire food system starting from the selection of seeds, sowing, manuring, drying, storing and feeding the family from the harvested product. Even though ...
Neuropeptide Y (NPY) was injected directly into the paraventricular nucleus of the hypothalamus (PVN) of satiated, brain-cannulated rats, and food and water intake were measured 0.5, 1, 2, 4, and 22 hr postinjection. NPY (24, 78, 235, 783, and 2351 pmol/0.3 mul) produced a large, dose-dependent increase in food intake as well as small increase in water intake. The latency to eat was about 10 mi...
Crops can be contaminated by fungi which produce mycotoxins. Many fungal strains are responsible for producing varied The research carried out so far has described over 400 different They have chemical and physical properties that significantly differ, they produced several existing fungi. intake of mycotoxins through food achieved directly, feeding on food, or indirectly from foods animal orig...
Symbiotic bacteria residing in the hindgut chambers of scarab beetle larvae may be useful in paratransgenic approaches to reduce larval root-feeding activities on agricultural crops. We compared the bacterial community profiles associated with the hindgut walls of individual Dermolepida albohirtum third-instar larvae over 2 years and those associated with their plant root food source among diff...
During the course of our history, humankind has been through different periods of agricultural improvement aimed at enhancing our food supply and the performance of food crops. In recent years, it has become apparent that future crop improvement efforts will require new approaches to address the local challenges of farmers while empowering discovery across industry and academia. New plant breed...
Influence of three different stocking densities, vitamin C supplementation of Daphnia spp. and feeding practice (i.e. mechanical, hand) on the success of dry feed habituation of pond reared pikeperch juveniles was investigated through one month trial. Pond reared pikeperch juveniles were harvested 42 days post-fertilisation (mean individual weight 1.1 ± 0.3g) and stocked into the experim...
Although several neural pathways have been implicated in feeding behaviors in mammals [1-7], it remains unclear how the brain coordinates feeding motivations to maintain a constant body weight (BW). Here, we identified a neuropeptide pathway important for the satiety and BW control in Drosophila. Silencing of myoinhibitory peptide (MIP) neurons significantly increased BW through augmented food ...
Agriculture is now facing the 'perfect storm' of climate change, increasing costs of fertilizer and rising food demands from a larger and wealthier human population. These factors point to a global food deficit unless the efficiency and resilience of crop production is increased. The intensification of agriculture has focused on improving production under optimized conditions, with significant ...
Transgenic modification of plants is a key enabling technology for developing sustainable biofeedstocks for biofuels production. Regulatory decisions and the wider acceptance and development of transgenic biofeedstock crops are considered from the context of science-based risk assessment. The risk assessment paradigm for transgenic biofeedstock crops is fundamentally no different from that of c...
the paper determined optimum farm plan for food security among smallholder farmers in imo state, nigeria. data were collected with structured and validated questionnaire from 180 smallholder crops farmers in imo state. data were analyzed using descriptive statistics (mean, frequency distribution and percentages), budgetary analysis and linear programming model. results show that the mean age of...
