Technical Field

The invention relates to the technical field of dairy cow feed production, in particular to a fully mixed feed for producing dairy cows rich in phytanic acid milk and a production process thereof.

Background

Greenfeed is an important food source for ruminants, containing abundant chlorophyll, lutein, β -carotene, proteins, and unsaturated fatty acids, which affect the nutritional metabolism and organoleptic properties of ruminants after ingestion by the animal.

After ruminants eat greenish feed, chlorophyll phytol groups of chlorophyll metabolize into Phytanic acid (3, 7, 11, 15-tetramethylhexadecanoic acid) after being released in the rumen, and are metabolized by the body and present in dairy and meat products. Since the main precursor of phytanic acid is phytol group in chlorophyll, the content of phytoacid in ruminant products is closely related to the content of ingested chlorophyll or phytol group.

Phytanic acid is a natural ligand, is an activator of peroxidase active receptor, has functions of resisting fatty acid oxidation and the like, and can not only reduce the risk of certain types of cancers, but also prevent certain metabolic syndromes. Phytanic acid has also recently been shown to have potential in improving T cell mediated effects and preventing autoimmune diseases. More functions of phytanic acid are gradually discovered, and phytanic acid becomes a novel functional fatty acid which is regarded as important. Reports indicate that the expression of PPARr mRNA of fat cells can be obviously improved after the phytanic acid is added into the bovine fat cells, which indicates that the phytanic acid can activate PPARr and further can regulate lipid and sugar metabolism, and some reports also indicate that more phytanic acid exists in the liver of ruminants. In rat hepatocyte experiments, the gene expression of phytanic acid participating in glucose metabolism through PPAR subtype regulation is proved, the potential effect of phytanic acid in insulin resistance management is shown, and the phytanic acid is considered to have obvious effect on relieving the lifestyle-related diseases such as fatty liver and obesity. It is noteworthy that phytanic acid in humans is derived almost exclusively from ruminant products, such as dairy products, meat products, which cannot be synthesized in mammals. The ingestion of phytanic acid rich ruminant products has positive implications for human health.

At present, the formula of the domestic full mixed feed for the dairy cows mostly takes basic nutritional ingredients as a proportioning standard, and the feeding of the formula can not produce milk with high added value; the coarse feed part of the domestic total mixed ration mostly takes silage corns as a main body, and although the corns have high energy and are one of indispensable components, the corns have low additional value and are not beneficial to producing milk with high additional value; most of the common high-added-value milk in the market is produced by adding active microorganisms or functional ingredients, which causes high cost and high price of fresh milk or dairy products.

In our previous studies, it has been found that chlorophyll is almost completely preserved in phytol, although 80% of it is decomposed after ensiling, in pasture grasses, which suggests that we can effectively preserve phytol resources in silage. In a feeding experiment in germany, it was shown that feeding 80% silage can significantly increase phytanic acid content in milk, but in the milk production process of large-scale feeding of cows, almost complete mixed feed (TMR) is fed, but until now, no TMR formulation concerns the added value in milk. Therefore, through the earlier exploration of a plurality of experiments such as pasture cultivation, production, feed preparation, dairy cattle raising and the like, a dairy cattle TMR formula capable of effectively improving the phytanic acid content in milk is finally developed.

Therefore, we propose a complete mixed feed for dairy cows, which is rich in phytanic acid milk, and a production process thereof to solve the above problems.
