THE EFFECTS ON CREATININE EXCRETlON OF CHANGES IN THE FERMENTATIVE ACTlVITY OF THE HIND GUT IN SHEEP'

Abstract

Four fenıale sheep were housed indoors in metabolistll crates ııııder eonditions qf continuoııs lighting and conslant ambienl temperature. All sheep prepared with rumen camııılas, ahomasal and ileal in.fusion caıhelers. Sheep were eontinuously inlused with volatile fat1y acids, minerals, bu/fer and casein. In addition these injusates, slGl'cllrmd cellulose ıııere iı{fused into the terminal ileum in order lo achieve diflerent levels of hind gw jel'll1entation. Creatınine excretfoııs were measured in the period q{nitrogen .free regimes and wheıı the maintenanee level oj nitrogen intake was given. The overall mean 'value q{ creatinine excretion for ıhe N-ji'ee regime Il'as 52.2 mg / kg°,75 / dayand ıras sil/ıilar lo the value reeorded when the mainfenanee level of nitrogen il/lake wa.\' given (52.0 mg / 1I:gO•75 i d). Ceaıinine excretion ıras not a.tfeeted by the precence or abcenee of {/ hiııd-gut ferıııenfation
