Embodiment 1

[0012] Example 1: Effects of Radix Puerariae Extract on Milk Production Performance and Blood Indexes of Dairy Cows

[0013] A total of 32 Holstein cows in mid-lactating parity 1-3 were selected and divided into control group, test 1 group, test 2 group and test 3 group according to the principle of similar milk production level, lactation stage and parity. The basal diet of each group is the same, the control group, the test group 1, the test group 2 and the test group 3 respectively add Pueraria root extract to the diet: 0, 12.5, 125 and 250 mg / kg, and carry out a 60-day feeding test . The results showed that the average daily milk production of test group 1, test 2 and test 3 increased by 17.47%, 9.68% and 11.36% respectively compared with the control group, and the daily milk production of the test group was more stable than that of the control group; The control group increased, but had little effect on milk protein and non-fat milk solids (p>0.05); plasma estradiol (E ...

Embodiment 2

[0014] Example 2: Effect of Pueraria Radix Extract on Inducing Lactation in Infertile Dairy Cows

[0015] Select 10 dry dairy cows with similar milk production, parity and body weight before induction, empty breasts, no milk and no reproductive diseases, and randomly divide them into control group and experimental group according to the pairing method, and each group is compared before and after. The control group and the test group were fed with the same basal diet, and 500 mg / kg of kudzu root extract was added to the diet of the test group. After feeding Pueraria root extract for 30 days, the control group and the test group were artificially induced lactation at the same time. On the 0d, 10d, 20d, and 30d at the beginning of the test, E 2 , PRL, GH, PRL, P 4 , INS, FSH, LH content. After successful induction, the average daily milk production in the first and second months and the total milk production in the first two months were measured. The results showed that: comp...

Embodiment 3

[0016] Example 3: Effect of Radix Puerariae Extract on Mammary Gland Development of Empty Dairy Goats

[0017] In this experiment, four healthy empty-pregnant dairy goats with similar parity, age, and body weight were selected to carry out self-control experiments before and after. The experiment was divided into a control period and a test period. The control period was 7 days, and the basal diet was fed; the test period was 15 days, and the basal diet + kudzu root extract 500 mg / kg was fed. On the 7th day of the control period and the 15th day of the test period, E 2 , GH, INS, PRL, FSH, LH, P 4 Content; at the same time, mammary gland tissue was taken to measure its DNA and RNA content, and histological sections of mammary gland were made. The results showed that the DNA and RNA contents in the experimental period were 16.50% and 24.30% higher than those in the control period, and the ratio of RNA / DNA increased by 6.87% (p>0.05); E 2 , INS and PRL content increased by 36...

Abstract

The invention discloses application of a kudzu root extract as a dairy stock feed additive and an application method thereof. The kudzu root extract is extracted from wild kudzu root, and the kudzu root mainly contains active ingredient of kudzu root isoflavone. By adding the kudzu root extract in the dairy stock feed, the productability of a milking cow can be improved, the inducing effect of a sterile cow is strengthened, and the mammary gland development of a nonpregnant milk goat is promoted and the milk yield is increased. The application method in which the kudzu root extract is used as the feed additive comprises that 12.5 to 500g of the kudzu root extract is added in each ton of the dairy stock feed.

Description

technical field [0001] The present invention relates to the use and method of Pueraria root extract, in particular to the use and method of Pueraria root extract as a feed additive for dairy animals. Background technique [0002] Mammalian milk has the functions of nutrition, immune protection and information transmission. Sufficient milk is the prerequisite for the survival and reproduction of newborn animals; milk and dairy products are the main nutritional food for human beings. With the improvement of people's living standards, dietary structure changes , People's demand for milk and dairy products has also greatly increased. The lactation performance of ruminants largely depends on the development of mammary glands, and the development of mammary glands and their lactation are mainly regulated by the endocrine system, and the nervous system is also involved in mediation. The development of mammary glands can be regulated by means of hormone regulation, and lactation ca...
