        육성토에 있어서 식염의 요구량에 관한 시험

        서경덕,강면희 ( K . D . Seo,M . H . Kwang ) 한국축산학회 1975 한국축산학회지 Vol.17 No.5

        During the period of 97 day s from June 4, 1974 to September 8, 1974, an experiment had been carried out at College of Agriculture, Korea University to compare effects on the feed consumption, body gain, efficiency of feed utilization and blood composition of growing rabbits that were fed with the experimental ration. In the experiment, 30 heads of 35-45 days-old rabbit were divided into 4 lots; levels of 0.0% (the control lot), 0.2% (A), 0.6% (B), 1.0% (C) NaCl were mixed with the experimental ration. The results obtained were summarized as follows. 1. In the feed consumption, no significant difference was obtained among A, B and C lots, but the feed consumption of B lot was increased much more than that of the otter lots. The results of control lot showed, however, statistically significant difference from any of other experimental lots at 5% probability level. 2. In the body gain, significant difference (p$lt;0.05) was obtained between control and the other lots. Though no significant difference was obtained from A, B and C lots, the body gain of B lot was higher than that of the other lots. 3. In the feed efficiency no significant difference was obtained in each four lots, but B lot was heigher than that of other treatment lots on the efficiency of feed utilization. 4. In the analysis of blood, the amount of blood total protein was 4.97㎎% in control lot, and the average amount of the other experimental lots was 5.72㎎%. Control of was less than the other experimental lots in amount of blood total protein, and no significant difference was showed through all the experimental lots. Amount of hematocrit was 26.67㎎% in control lot, average 34.33㎎% in the other experimental lots. From the hematocrit contents of the control and other experimental lots, no significant difference was obtained at 5% probability level. In rabbits, the content of blood serum albumin was 4㎎%, blood serum sodium 165.25mEq/l, blood serum potassium 6.45mEq/l. Statistically, through all lots including the control lot no significant difference was obtained in the contents of blood serum albumin, blood serum sodium and serum potassium.
