    Here’s another one that shows the same results:

    Feeding trial. Data pertaining to the feedlot trial are presented in table 1.
    Control lambs had a 50% incidence of urinary calculi. The feeding of ammonium chloride resulted in a significant (P < . 01) reduction of urinary calculi with only
    one nonobstructive case occurring in lambs on this treatment. Lambs receiving
    calcium chloride had one obstructive case of calculi early in the experiment and two
    additional cases that were encountered at slaughter. This reduction attributed to
    calcium chloride, 16% incidence vs. a 50% incidence in the controls, was significant
    at the 5% level of probability. Feeding 1% potassium chloride significantly (P < . 05)
    increased the incidence of urinary calculi resulting in a total (obstructive plus
    nonobstructive) incidence of 85%. In this instance, obstructive cases alone
    accounted for a 35% incidence.

    While feeding 4% sodium chloride or 2% calcium carbonate appeared to lower the
    incidence of urinary calculi, the reductions were not significant. Data previously
    reported from this station showed that the protective effect of calcium carbonate
    added to high-phosphorus rations improved up to the highest calcium-to-phosphorus
    ratio (2. 3:1) used. The calcium-to-phosphorus ratio of the 2% calcium carbonate
    ration fed in the current experiment was 1.7 :1.

    Lambs receiving ammonium chloride, potassium chloride or sodium chloride had the
    lowest feed consumption and, subsequently, the lowest average daily weight gains.
