説明
A study was undertaken to determine whether propylene glycol supplemented in the basal diets consist of concentrates, grass hay and herbage influenced on growth rate and rumen volatile fatty acids of lambs or not. Twenty five male Corridale lambs weighing average 31.7kg were divided into two experimental and control groups, with the experimental groups respectively, receiving 0.5g and 1.0g per kg B. W. of propylene glycol in daily ration every other day throughout 104 days. Propylene glycol significantly increased weight gain of lambs (P⟨0.05), especially at initial stage for about 30 days: average daily gains of each experimental group were 104.2g and 104.9g, while that of control group was 78.2g. The rumen liquor samples withdrawn about 5 hrs after feeding were chemically analyzed for volatile fatty acids, free ammonia and pH. Rumen propionate concentrations of both experimental groups significantly increased at initial stage (P⟨0.05). Total volatile fatty acids of experimental groups also showed a tendency of increase more or less than those of control group at every stages. No significant difference between control and experimental groups was found in other chemical constituents, except VFA of the rumen liquor. Three lambs of each group were slaughtered. The weight percentage of wool, dressed carcass and red meat-fat ratios of each experimental group increased more or less than that of control group. Therefore, it was suggested that propylene glycol supplemented in the ration might have given a good result for fattening techniques of ruminants, where the effect of propylene glycol on weight gain seemed to have been brought about by the change in the rumen fermentation rather than by energy sources of it.
