Individual feeding of honey bees: modification of the Rinderer technique
(Int Bee Research Assoc, 2013-12)
Currently, inoculation with substances or infective microorganisms of individual honey bees involves many technical problems, such as long time periods of handling and a tedious manipulation of the bee to achieve the ...
Mycotoxins and Mycotoxigenic Fungi in Poultry Feed for Food-Producing Animals
(Hindawi Publishing Corporation, 2014-07)
Moulds are capable of reducing the nutritional value of feedstuff as well as elaborating several mycotoxins. Mycotoxin-contaminated feed has adverse effects on animal health and productivity. Also, mycotoxins may be carried ...
Growth, survival, body composition and amino acid profile of Macrobrachium borellii against the limitation of feeds with different C:N ratios with comments about application in integrated multi-trophic aquaculture
(Wiley Blackwell Publishing, Inc, 2020-10-04)
One way to attain more sustainable aquaculture systems is through the species diversification and optimization of the feed input, such as obtained by integrated multi-trophic aquaculture (IMTA). Macrobrachium borellii is ...
Inter-population differences in feeding ecology under nitrogen-limited diets: Field growth and the role of cannibalism in limiting/improving reserve accumulation
(Wiley Blackwell Publishing, Inc, 2019-06)
Growth is determined by an organism's physiology, physical environment, and biological conditions, including food availability and any intra- and inter-specific interactions that can affect feeding activity. To analyse how ...
Dietary protein quality and proper protein to energy ratios: A bioeconomic approach in aquaculture feeding practices
(2019-05-01)
Supplementing high levels of dietary crude protein in the absence of amino acid balance and enough energy in fish diets may results in reduced growth, improper feed intake and poor protein utilization efficiency coupled ...
