梁昇柱 건국대학교 1977 論文集 Vol.6 No.1

This experiment was conducted to determine the feeding value of kelp meal collected from Daejung, Cheju Island for laying hens. A total of 240 births of 28 week-old babcock hen was alloted to 4 treatments, 4 replicates per treatment, according to completely randomized design to find out the effects of substitution levels (0, 5, 10 and 15%) of kelp meal for wheat bran on the laying performance of experimental thirds for 70 days. The results obtained are summarized as follows : 1.Kelp meal studied were analyzed for the contents of proximate general composition (moisture 13.73%, crude protein 9.66%, crude fat 1.81%, crude fiber 9.08%, crude ash 21.96%, nitrogen free extracts 43.86%). 2.Egg-laying rates for C (control allot) and T1 (5% allot) were higher than those of T2 (10% allot) and T3 (16% allot), but no statistical significant difference was found among all treatments. 3.In feed intake, the statistical significant difference (p < 0.06) was observed among all treatments, and the amounts of feed take for T1 was higher than mothers, in the other hand those for T3 was lower than ethers. The results of feed conversion was the some with that of feed intake. 4.The average egg weight for T3 was higher than ethers, but there was no statistical significant difference among all treatments. The weight of egg shelf was showed the some results with egg weight. Egg folk colour for T2 and T3 was more dark than C and T1. 5.In the nutrient utilizability, no statistical significant difference was found among treatments, but the crude fiber utilizability was showed the significant difference among treatments. Especially thc result of T2 was lower than ethers. 6.Based on these results described above, it boomed that the substitution of wheat bran with kelp meal up to 5% level could be uses without adverse effect in the ration for laying hens.

This stady was carried out to investigate the effects of parity, stage of lactation, supplying nutrients, condition of management. milking hygiene, calving season and milking season on the milk yield, milk comp onents. pH and bacterial qualiy of raw milk samples collected from 56 Holstein cows of 7 ranches in Chju-Do area from July 1987 to June, 1988. The results obtained from this study are summarzed as follows: 1. The average daily milk yield, 305 day cor:ected milk yield and milk fat yield were 20.87kg 6285.88kg and 236.09kg respectively. The milk yield and milk fat yield of 3rd parity were higher than that of other party group. In the effect of calving season, the performance of Winter calving cows showed the highest rasults and that of Autumn calving cows were the lowest. The performane of milk yield was significantly effected by the level of nutrients, conditions of management and milking hygiene. 2. In the aspect of milk yield and milk fat yield in the lactation stage, the milk yield was highest at the firot one month. In the effect of milking season, the results in April and June were the highest, and those in January and February were the lowest. In the effect of milking time, the yield of milk was higher in the morning than in the evening. 3. The average values of raw milk composition were found to be milk fat, 3.75%; protein, 3.27%; lactose, 4.57%; total solids. 12.57 %; solids-not-fat, 8.75 %. The component ratio of milk fat, total solids and solids-not-fat 3rd parity were higher than that of other parity group. But in the component ratio of protein and lactose, there were no significant differences among all the parity groups. The milk fat percentage of Winter calving cows were the highest and that of Summer calving cows were the lowest, in the effect of calving season. In contrast to the milk yield, higher percentage of milk fat appeared in the morning than in the evening. The percentage of all the kind of milk componets were higher in the milk produced from cows supplied sufficient nutrients than that produced from cows supplied deficient nutrients. but the condition of management and milking hygiene had no effect on the milk fat percentage. 4. In the effect of the lactation stage, the milk fat percentage was lowest at 5 months after calving but the percentage of protein and total solids were lowest at the first months. Referring to the monthly variation in average raw milk compositions, the contents of fat and total solids showed the lowest results in July and the highest in January. But protein content were lowest in August and highest in December. 5. The average values of the pH. titratable acidity and number of Somatic cell of raw milk found to be 6.72, 0.173 and 26.2 × 10^(4)/ml respectively. These Values were considerably affected by the management condition and milking hygiene of the experimental ranches. 6. The average number of living bacteria and coliform bacteria were 13.49X 10^(6) cfu/ml and 175.43×10^(3) cfu/ml respectively. In the bacteriological quality of raw milk samples, there were significantly great differences among the experimental ranches.

This study was carried out with 56 milking cows in the 6 daily farms, in order to have a grip of the actual condition of dairy cattle feeding and to get the materials for establishment of the reasonable feeding system of dairy cattle raised in Cheju-Do area. The amounts of feeds supplied to each milking cows, the levels of crude fiber in the feeds, and the amounts and levels of crude fiber in the feeds, and the amounts and levels of Dry Matter, energy(total Digestible Nutrients) and protein were investigat-ed and analyzed. The results obtained are summarized as follows; 1. Average amount of DM per cow per day was 17.97±1.501kg. This was 91% of the amounts of possible maximum intake. The range of the amounts and levels of DM fed were 15.82-25.05kg and 63-146% respetively. The results mean that DM fed is insufficient, that the considerable unbalance be-tween energy fed and protein fed is produced on account of such great range, and that the feeding system for milking cows in much unreasonable. The amounts and levels of DM by ranches and parity were showed considerable variations 2. The average amount of concentrates per cow per day was 8.66kg. The range of it was 5-15kg and was much variable. 3. The average level of roughagedthe rate of roughages per DM fed) was 24.77% and was sufficient to some degree. But the range of it was 13.72-41.1646 and the variation was much considerable, espe-cially by seasons and parity. 4. The average requirements of energy(TDN) and protein were 12.45kg and 2.69kg respectively. And the average amounts of energy(TDN) and protein fed were 12.25kg and 2.64kg respectively. The average levels(the rate of amounts fed per requirements) were 99.0% and 98.8% respectively. 5. The range of energy(TDN) fed and protein fed were 7.42-19.0lkg and 1.45-7.11kg respectively. And the range of energy and protein levels(the rate of amounts fed per requirements) were 59-161% and 68-176% respectively. These results mean that the considerabble imblance between erergy(TDN) fed and protein fed is still in existence, that the situations of severe overfeeding and under-feeding co-exist in suppling feeds to dairy cattle, and that the feeding method and system for dairy cattle in Cheju-Do area is much unreasonable and is fallen behind. The energy(TDN) and protein feedings by ranches, panty and seasons were showed considerable variations 6. Judging from these results obtained, I think that the most imporbnt things of dairy cattle feeding in Cheju-Do area were deficiency of knowlege and low level of technology for dairy cattle feeds and nu-trients, and were especially the unreasonable method and system for dairy cattle feedings.

In order to examine the value of citrus byproducts as livestock feed, 4 types of CBS were made: T1; wet CMS with high moisture. T?; pre-wilted CMS with low moisture. T3; wet CPS with high moisture. T4; pre-wilted CPS with low moisture. Digestion trials were carried with 3 sheep equipped with rumen fistulars. Rumen liquor pH and total VFA were investigated during the trial period. The daily intake of the trial feed (CBS+hay) was 0.76-0.78㎏ DM (1.8-1.9% by body wt.). Feeding CBS showed the effect of increasing the feed. intake. Compared with high moisture CBS, low moisture CBS increased feed intake and digestibility, and was weak in the tendency of lowering rumen liquor pH. Compared with CPS, CMS showed a tendency more similar to low moisture CBS. Feeding CBS had the effect of increasing urine excretion, water intake and digestibility of DM and DNFE. When fed CBS the pH and total VFA in rumen liquor were lower than when fed hay. Such tendency was shown in the case of feeding high moisture CBS compared to low moisture CBS. The digestibility of CBS had no relationship with pH, but there was a statistical significant correlation between total VFA in rumen liquor and digestibility of CBS. It appears from the results of these trials in the making and utilization of CBS that CMS was better in all respects than CPS and prewilted CBS with low moisture (about 76%) was more effective than wet CBS with high moisture (about 83%).
