Abstract: | The chicken, which has no endogenous lactase, was assessed as a possible model for studies on lactose intolerance. The ability of yoghurt to reverse changes induced by lactose was examined. In the caecum lactose had little effect on the viable counts of three groups of organisms which utilize lactose and no effect on the water content. It suppressed body weight, induced gas formation in the caecum and slightly lowered caecum pH. None of these effects was reversed by yoghurt.The β-glucuronidase activity of the caecal contents was slightly reduced by lactose and markedly reduced in chickens receiving lactose and yoghurt. The additional effect of yoghurt also occurred with yoghurt which had been heated to kill the bacteria and inactivate the lactase. The suppression of β-glucuronidase activity was also achieved by supplements of yoghurt alone. |
