this study was carried out on 10 crossbred male sheep aged 1-1.5 year. an innervated crosskopf abomasal fundic pouch was made in each animal and effect o f starvation an d feeding on abomasal volume and composition were assesed . the results indicated that during starvation, volume of secretion , total acidity and k concentration decreased to a low level, while ph and na concentration reached h...

Aim: This review was made to determine the effects of using tannin on fermentation quality and animal nutrition as a different alternative additives used prevent spoilage silages, which are widely in today's livestock. Tannins polyphenolic compounds natural with characteristic odor, acrid taste, colors from yellow white, can also be found feeds such gallnut, oak, chestnut rapeseed, broad bean, ...

The use of whole-food (grain meal contained in feed) animal-feeding studies to support the safety assessment of genetically modified crops has been contentious. This may be, in part, a consequence of poorly agreed upon study objectives. Whole-food animal-feeding studies have been postulated to be useful in detecting both expected and unexpected effects on the composition of genetically modified...

Vector infection by some animal-infecting parasites results in altered feeding that enhances transmission. Modification of vector behavior is of broad adaptive significance, as parasite fitness relies on passage to a new host, and vector feeding is nearly always essential for transmission. Although several plant viruses infect their insect vectors, we have shown that vector infection by a plant...

in pasture-based milk production systems, using available farm resources in order to reduce feeding costs, the composition and functional properties of dairy cows’ milk are of considerable importance to the dairy farmer, manufacturer and consumer. basically, there are three options for altering the composition and/or functional properties of milk: 1) cow nutrition and grazing management, 2) cow...
