A significant challenge facing the world today is the expected 34% increase in the human population by 2050, which will require 70% more food from existing natural and land resources (FAO, 2009). Thus, the efficiency of natural resource use must be improved to meet the food security goals for a growing population while protecting the environment (FAO, 2009). Due to their ability to utilize cell...

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...

T HE mechanisms regulating feed intake appear to be the same mechanisms that control energy exchange. The physiological functions brought into play are numerous and involve chemosensitive areas, reflex responses and integrative function of the central nervous system. Aside from the primary physiological factors limiting feed intake, a close relationship exists in ruminants between the content o...

in the process of milk production, the highest cost relates to animal feed. based on reports provided by the experts, around seventy percent of dairy livestock costs included feed costs. in order to minimize the total price of livestock feed, according to the limits of feed sources in each region or season, and also the transportation and maintenance costs and ultimately milk price reduction, o...

Enrichment of live foods by essential nutrients such as highly unsaturated fatty acids is an important tool for improvement of larval fish quality. In this study, nutritional effects of Artemia urmiana enriched by fish and plant oils on growth, survival rate, body compositions and resistance against thermal, salinity and hypoxic stresses in rainbow trout, Oncorhynchus mykiss were examined. Six ...

The European Pond Turtle is a predominantly aquatic species, generally assumed to feed exclusively under water by using hydrodynamic mechanisms. We analysed the kinematics of the aquatic food uptake and food transport by using high-speed videos with 500 fps. The analyses revealed that subadult E. orbicularis use compensatory suction for food uptake, but the food transport is performed by a comb...

results aflatoxins have been found in many food products in iran. conclusions it is necessary to detect aflatoxins in foods and food products as early as possible, before they enter human or animal bodies. there is a high consumption of milk and dairy products in iran, and the proper management of animal foods can help to decrease the aflatoxins in milk. evidence acquisition in consideration of...

The impact of melamine-contaminated animal feed ingredients on food safety has become a major public concern ever since melamine was identified as the organic compound responsible for the deaths of a significant number of cats and dogs in 2007 by way of adulterated pet food. Melamine, a common industrial chemical often added to resins to improve flame resistance and proposed as an alternative f...

plastics are well-established for convenient and safe packaging and distribution of food and feed goods. at present, this special sector of the plastic market displays remarkably increasing quantities of its annual production. caused by the ongoing limitation and strongly fluctuating prices of fossil feedstocks, classically used for plastic production, there is an evident trend to switch toward...

Isotopic and nuclear techniques play an important role in food and agriculture, health and industry. In the agricultural sciences and food technology sectors, recent research has elucidated the new potential application of radiation for microbial decontamination, food preservation, improve the nutritional quality of  foods  and effectively utilise its potential as human food or animal feed. The...
