The influence of roughage intake on the occurrence of oral disturbances in captive giraffids
Feeding behaviour of giraffe and okapi in captivity can differ significantly from the state in the wild. Duration and complexity of feeding and ruminating behaviour, and total amount of food ingested, are o�en reduced, while the energy content of the diet is increased compared to the wild. As known from domestic ca�le in intensive keeping systems, oral disturbances like tongue-playing or lickin...
متن کاملPhysiological Limitations to Using Concentrates to Increase the Digestible Energy Intake of Ruminants given Roughage Based Diets
The low intake and digestibility of low-quality roughages such as mature forages or crop residues often results in a digestible energy intake insufficient for a desired level of production. One alternative to increase digestible energy intake is to provide supplementary concentrates of high digestibility. ‘ Associative effects on forage fibre digestion may occur when roughage and concentrate ar...
متن کاملMeasuring fiber and its effectiveness in ruminant diets
It appears that ruminants such as cattle and sheep evolved as forage consumers. Plant cell walls, which we measure as fiber, cannot be digested by animals, but must be fermented by microorganisms. Fermentative digestion of fiber is slow and incomplete, and ruminants have developed many attributes that result in efficient digestion. They swallow large particles of forage and selectively retain t...
متن کاملFactors Limiting Feed
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...
متن کاملThe Role of Fat in Ruminant Nutrition
Ruminants have been domesticated and exploited by man for two major reasons. Firstly, they are able to digest roughage and thereby derive energy for productive purposes because they possess a functional rumen. Secondly, they produce meat and milk which are of nutritive value to man. Much of this paper will cover aspects pertaining to the above with particular emphasis on fat intake and metaboli...
