The effect of temporary feed restriction on calves with ruminal acidosis

A prospective study was conducted on 87 calves, less than 4 weeks of age, w ith ruminal acidosis to determine the effect of temporary feed withdrawal o n their probability of recovery. The results indicated that this was an eff ective method of treatment, but with some provisions. First, the withholdin g of feed is indicated only if the pH of the ruminal fluid is less than 6.0 following ruminal lavage on two consecutive days. Secondly, the withholdin g of feed for one or two days (three to five meals) produced a better effec t than a more prolonged withholding of feed; during this period the affecte d calves were given a parenteral source of nutrition comprising 2 l of phys iological saline and 2 l of a glucose solution over 24 hours. Finally, cach ectic calves or those with a bad prognosis, from clinical pathological exam inations, due to intercurrent disease should be euthanised.
