Problems solved by technology

Adding vegetable oil rich in linolenic acid will reduce the content of linoleic acid in the feed; on the contrary, adding vegetable oil rich in linoleic acid will reduce the content of linolenic acid in the feed, and it is difficult to achieve both
Studies have also shown that adding a large amount of high unsaturated fatty acids to dairy cow feed will affect the amount of food intake of dairy cows, affect the digestion of forage grass by dairy cows, and then reduce milk production.

Embodiment 1

[0048] Formulate the basic feed for dairy cows according to Table 1, add 5% of additives, 60% of rubber seed oil and 40% of rubber seed kernels in the additives. Select 10 Holstein dairy cows with a milk production period of 50-200 days as the implementation object, and feed them with basic feed for 30 days, and then gradually switch from basic feed to feed with 5% additives after 10 days of feeding. Feed for another 30 days after the feed change. For 30 days before and after the feed change, the food intake and milk production of the cows were recorded every day, and milk samples were taken every day, and the milk samples were accumulated for 30 days before and after the feed change, and the fatty acid composition of milk fat was analyzed. The results are shown in Table 2.

Embodiment 2

[0055] Formulate the basic feed for dairy cows according to Table 1, add 6% additives, 50% of rubber seed oil and 50% of rubber seed kernels in the additives. Select 10 Holstein dairy cows with a milk production period of 50-200 days as the implementation object, and feed them with the basic feed for 30 days. After 10 days of feeding, gradually switch from the basic feed to the feed with 6% additives. Feed for another 30 days after the feed change. For 30 days before and after the feed change, the food intake and milk production of the cows were recorded daily, and milk samples were taken every day, and the milk samples collected for 30 days before and after the feed change were accumulated to analyze the milk fat fatty acid composition of the milk. The results are shown in Table 3.

Embodiment 3

[0060] A method for producing milk rich in omega-3 fatty acids and conjugated linoleic acid, comprising the steps of:

[0061] (1) Configure the basic feed for dairy cows according to Table 1, add the mixture of rubber seed oil and rubber seed kernels to the basic feed for dairy cows, and mix evenly; the quality of the mixture is 2% of the quality of the basic feed, and the rubber seed oil in the mixture The mass percentage composition is 100%, and the mass percentage composition of rubber seeds is 0%;

[0062] (2) Use the feed obtained in step (1) to feed cows with a milk production period of 50-200 days for 8-15 days to produce milk rich in omega-3 fatty acids and conjugated linoleic acid. After testing, the content of omega-3 fatty acid in milk fat is 0.62%, and the content of conjugated linoleic acid is 2.15%.

Abstract

The invention relates to milk rich in omega-3 fatty acid and conjugated linoleic acid, a production method thereof, and feedstuffs used in production, which belong to the technical field of rumination animal feedstuffs, and rumination animal milk and milk products. The production method provided by the invention is realized by adding 2-8 percent of rubber seed oil and rubber seed nuts in basic feedstuffs of dairy cows; in the milk obtained by production, the content of the omega-3 fatty acid is larger than 0.6 percent and is more than two times of common milk, the content of the conjugated linoleic acid is larger than 2.0 percent and is more than four times of the common milk, the content of vaccenic acid is larger than 11 percent and is more than six times of the common milk, the content of unsaturated fatty acid in the milk is increased by more than 60 percent compared with the common milk, and the content of saturated fatty acid in the milk is reduced by more than 25 percent compared with the common milk. According to the production method provided by the invention, inedible oil is used, the cost is low, and the feeding and the milk production of the dairy cows cannot be affected.

Description

technical field [0001] The invention belongs to the technical field of ruminant feed, ruminant milk and dairy products, and specifically relates to a milk rich in omega-3 fatty acid and conjugated linoleic acid, a production method thereof, and a feed used in production. Background technique [0002] Milk is an important nutritious food and is consumed in huge quantities. In addition to drinking liquid milk (including milk powder) directly, milk can be further processed into a variety of dairy products, such as cream, cheese, butter, yogurt, desserts, ice cream and so on. Milk is rich in fat, protein, sugar and other nutrients. The fat in milk is one of the important sources of human fat, and the reasonable degree of its fatty acid composition has a great impact on human diet health and fatty acid dietary balance. [0003] However, compared with human milk, the composition of fatty acids in milk fat is not reasonable, the main manifestations are: ①The content of saturated ...
