３一
実施例１
乳牛にクロレラ熱水抽出物（クロレラエキス）からなる
乳質改善剤を一定期間投与し、その乳牛から搾乳した牛
乳について、脂肪分、無脂肪固形分、蛋白質、および細
胞片数を検査した。31 Example 1 A milk quality improving agent consisting of a hot water extract of chlorella (chlorella extract) was administered to a dairy cow for a certain period of time, and the fat content, non-fat solid content, protein, and number of cell fragments were measured for the milk milked from the dairy cow. Inspected.
試験は次のように行った。The test was conducted as follows.
（乳質改善剤）
クロレラ粉末３０ｇを水ＩＱに懸濁させ、１００℃で３
０分間熱水抽出して、抽出液を遠心分離し、その上澄液
を乾燥して、粉末状抽出物を得、この粉末状抽出物を３

Hot water extraction was carried out for 0 minutes, the extract was centrifuged, and the supernatant was dried to obtain a powdered extract.
A milk quality improver was prepared by dissolving it in water to a concentration of g/Q.
（供試乳牛）
健康な乳牛２２頭を、１１頭づつの２群に分け、方を乳
質改善剤を与える試験群、他方を乳質改善剤を与えない
対照群とした。両群とも同様に慣行的方法で飼育した。(Test Dairy Cows) Twenty-two healthy dairy cows were divided into two groups of 11 cows each, one of which was a test group given a milk quality improver and the other a control group not given a milk quality improver. Both groups were reared in the same conventional manner.
（試験方法）
試験群には、上記乳質改善剤を１日当り１０Ｃ１ｍｆｌ
の割合で４週間毎日与えた。そして投与前、投与１週間
後、２週間後、３週間後、および４週間後に搾乳した牛
乳について、脂肪分、無脂肪固形分、蛋白質、および細
胞片数を検査した。(Test method) The test group was given 10C1mfl of the above milk quality improver per day.
was given daily for 4 weeks. The milk expressed before administration, 1 week, 2 weeks, 3 weeks, and 4 weeks after administration was examined for fat content, nonfat solid content, protein, and number of cell debris.
脂肪分、無脂肪固形分および蛋白質は常法により測定し
た。細胞片数はブリード法で測定した。Fat content, nonfat solid content, and protein were measured by conventional methods. The number of cell debris was measured by the bleed method.
各群１１頭について測定した平均値を表１に示す。Table 1 shows the average values measured for 11 animals in each group.
脂肪分は、対照群で試験前に３．５％前後であったが、
４週間後には３．２％まで下降したのに対して、試験群
は投与前３．５％を下回っていたが、２週間後から上昇
し、４週間後には３．６％まで上昇した。無脂肪固形分
は、対照群で終始８．５％ラインを上下していたが、試
験群では２週間後に８．５％まで下がったが、３週間後
、４週間後には８．７％まで回復した。蛋白質は、対照
群で終始３．０％のラインを上下していたが、試験群で
は当初２．９％であったものが３週間後以降３．０％以
上となった。細胞片数は、対照群は増加傾向を示したが
、試験群は３週間後以降５０，０００個／ｍＱ 程度
に下降した。The fat content was around 3.5% in the control group before the test, but
The rate decreased to 3.2% after 4 weeks, whereas in the test group it was lower than 3.5% before administration, but it increased after 2 weeks and rose to 3.6% after 4 weeks. Fat-free solid content remained above and below the 8.5% line throughout in the control group, but in the test group it fell to 8.5% after 2 weeks, but rose to 8.7% after 3 and 4 weeks. I have recovered. The protein content in the control group fluctuated above and below the 3.0% line from start to finish, but in the test group, what was initially 2.9% increased to over 3.0% after 3 weeks. The number of cell fragments showed an increasing tendency in the control group, but decreased to about 50,000 cells/mQ after 3 weeks in the test group.
以上の結果から分かるように、クロレラエキスを乳牛に
投与した場合、投与後２〜３週間後から投与効果が現れ
、牛乳中の脂肪分、無脂肪固形分、蛋白質の含有量が増
加し、細胞片数の増加が抑制される。As can be seen from the above results, when chlorella extract is administered to dairy cows, the administration effects appear 2 to 3 weeks after administration, and the fat content, non-fat solid content, and protein content in milk increase, and the cellular The increase in the number of pieces is suppressed.
実施例２
乳牛にクロレラ熱水抽出物を４週間与え、その乳牛から
得られる乳量の変化を測定した。群当りの頭数を１０頭
とした以外は実施例１と同様にして乳牛を飼育した。Example 2 Chlorella hot water extract was given to dairy cows for 4 weeks, and changes in milk yield obtained from the cows were measured. Dairy cows were raised in the same manner as in Example 1 except that the number of cows per group was 10.
乳量は、試験群で投与前は平均１９．８ｋｇ／日であっ
たものが、４週間後には平均２０．６ｋｇ／日とやや増
加した。対照群では、投与前の平均２１４ｋｇ／日が４
週間後の平均２１．６ｋｇと増加はみられなかった。Milk production in the test group was 19.8 kg/day on average before administration, but increased slightly to an average of 20.6 kg/day after 4 weeks. In the control group, the average weight before administration was 214 kg/day.
After a week, the average weight was 21.6 kg, and no increase was observed.
本発明によれば、微細藻類抽出物を成分とするため、乳
牛等から搾乳した乳質を改善することができるとともに
、乳量を増加させることができる。According to the present invention, since the microalgae extract is used as a component, the quality of milk milked from a dairy cow or the like can be improved, and the amount of milk can be increased.
