Problems solved by technology

[0004] Since the conversion rate of linoleic acid to conjugated linoleic acid by a single probiotic is limited, different probiotics are usually added to increase the conversion rate of conjugated glyceric acid, but different types of probiotics are effective in converting conjugated linoleic acid. Linoleic acid does not always play a synergistic role, and there may even be mutual inhibition. Therefore, in order to improve the national physical fitness and also bring considerable economic benefits to dairy companies, how to produce linoleic acid rich in conjugated There is still room for improvement in the problem of linoleic acid milk

Embodiment 1

[0049] This embodiment discloses a lactating cow feeding method for increasing the content of conjugated linoleic acid in milk, comprising the following steps:

[0050] Step 1, preparation of probiotic bacteria liquid:

[0051] Add Lactobacillus reuteri to MRS liquid medium, seal it, and culture it statically at 35°C, inoculate 1% of the bacteria, and cultivate it for 24 hours to obtain a bacterial concentration of 10 9 CFU / mL Lactobacillus reuteri bacteria liquid;

[0052] Add Lactobacillus acidophilus into the MRS liquid medium, seal it, and culture it statically at 35°C, with an inoculation amount of 1%, and cultivate it for 24 hours to obtain a bacterial concentration of 10 9 CFU / mL Lactobacillus acidophilus bacterial solution;

[0053] Add Propionibacterium frescheri subsp. Sherley into the MRS liquid medium, seal it, and culture it statically at 35°C. The inoculated amount is 1%, and cultivated for 48 hours to obtain a bacterial concentration of 10 9 CFU / mL of Propion...

Embodiment 2

[0061] The difference with embodiment 1 is:

[0062] In step 2-1, replace 1.5% rapeseed oil with 5% rapeseed.

[0063] In step 2-2, the total volume of Lactobacillus reuteri bacterium liquid, Lactobacillus acidophilus bacterium liquid, Propionibacterium frescherii subsp. The added volume ratio of each bacterial solution was 1:0.6:0.6:0.6.

Embodiment 3

[0065] The difference with embodiment 1 is:

[0066] Step 1, prepare probiotic freeze-dried powder: prepare active lactic acid bacteria content of 10 10 CFU / g of Lactobacillus reuteri lyophilized powder, Lactobacillus acidophilus lyophilized powder, Propionibacterium frescherii subsp.

[0067] In step 2-1, replace 1.5% rapeseed oil with 1% soybean oil.

[0068] In step 2-2, add the freeze-dried powder of Lactobacillus reuteri, the freeze-dried powder of Lactobacillus acidophilus, the freeze-dried powder of Propionibacterium frescherii subsp. For freeze-dried powder, the mass ratio added is 1:0.9:0.9:0.9.

Abstract

The application relates to the field of animal husbandry, and specifically discloses a lactating cow feeding method for increasing the content of conjugated linoleic acid in milk. Including the following steps: the total number of colonies fed to each lactating cow per day is greater than 10 11 CFU of probiotics and rations rich in unsaturated fatty acids, continuously feeding lactating cows for 4 weeks or more; Propionibacterium subsp. fischeri; the colony ratio of each strain of the probiotics fed to lactating cows daily is 1: 0.6~1.6: 0.6~1.6: 0.6~1.6; the content of the unsaturated fatty acid accounts for 5% or more of the total mass of dry matter in the diet. The method of the present application for feeding lactating cows can not only obtain milk rich in conjugated linoleic acid, but also significantly improve the feed intake, milk yield, milk protein content and antioxidant capacity of the lactating cows.

Description

technical field [0001] The present application relates to the field of animal husbandry, more specifically, it relates to a feeding method for lactating cows for increasing the content of conjugated linoleic acid in milk. Background technique [0002] With the improvement of living standards and health awareness, people have taken dairy products as an important nutritious food in daily life. With the development of the national economy and the change of residents' dietary concepts, functional dairy products with nutrition, characteristics and health care have become a consumer product. Mainstream, the content of milk components in raw milk is an important indicator to measure the quality of dairy products. There are more and more researches on this aspect. Conjugated linoleic acid is being used more and more for its excellent health care and disease resistance functions. Research and medical institutions at home and abroad have paid attention to the fact that conjugated lino...
