Description

Use of odd-carbon saturated fatty acids, fatty acid esters thereof and fatty acid salts thereof for improving animal meat quality or dairy quality Technical Field The invention belongs to the technical field of animal breeding. And more particularly to the use of odd-carbon saturated fatty acids, fatty acid esters thereof, fatty acid salts thereof for improving animal meat quality or dairy quality. Background In the field of animal farming, fat is an essential substance for animal growth, as are carbohydrate and protein. The fatty acid can be quickly absorbed and utilized by animals to provide energy, and has positive effects on aspects of intestinal health, immunoregulation and the like. Various fatty acids have different functions and actions in animals. Patent CN106212932a discloses that unsaturated fatty acid can reduce cholesterol content in pig body, raise lean meat percentage, and the unsaturated fatty acid has "non-polyester" characteristic, can prevent fat deposition, can retain relative fluidity of cell membrane, and further can raise taste and flavour of pork quality. Saturated fatty acids can increase the feed intake and digestion and absorption capacity of animals, increase protein synthesis, rate of weight gain and immunity, and help reduce disease occurrence and mortality. It can be seen that unsaturated fatty acids and saturated fatty acids vary greatly in their functional roles and uses based on the difference in structure. In addition, "effect of different carbon chain length fatty acids added in diet on milk cow production performance and milk fat acid composition, animal nutrition report, cui Hai" discloses that the effect of adding long chain fatty acids (mixture of sixteen fatty acids, eighteen fatty acids and the like) on milk fat rate and milk protein rate of milk quality is not obvious, and the milk fat rate is reduced instead. At present, most of the fats used in animal feeds are even saturated carbon chain fatty acids, the main difference between odd-chain saturated fatty acids and even-chain saturated fatty acids is the number of carbon atoms, and the structural difference leads to different products after the fatty acid beta is oxidized and metabolized, wherein the metabolism products of even-chain fatty acids are mainly acetyl coenzyme A, and the metabolism products of odd-chain fatty acids are mainly propionyl coenzyme A. In the tricarboxylic acid cycle, acetyl-coa combines with oxaloacetic acid to form citric acid, which after entering the cycle is thoroughly oxidized to form carbon dioxide and water, releasing energy for ATP synthesis. propionyl-CoA is converted to methylmalonyl-CoA and ultimately to succinyl-CoA, which enters the tricarboxylic acid cycle (ADVANCES IN Nutrition Volume 7,Issue 4,July 2016,Pages730-734). It can be seen that odd-chain saturated fatty acids are significantly different from even-chain saturated fatty acids in terms of their conversion and metabolism in animals, based on structural differences. Therefore, it is an urgent technical problem to be solved to explore what remarkable role the odd-chain saturated fatty acids have on the animal body. Disclosure of Invention Based on the above-mentioned prior art problems, it is a primary object of the present invention to provide the use of odd-carbon saturated fatty acids, odd-carbon saturated fatty acid esters and/or odd-carbon saturated fatty acid salts for improving the meat quality of animals. A second object of the present invention is to provide the use of an odd-carbon saturated fatty acid, an odd-carbon saturated fatty acid ester and/or an odd-carbon saturated fatty acid salt for improving the quality of animal milk. A third object of the present invention is to provide a method for improving the quality of animal meat or animal milk. A fourth object of the present invention is to provide the use of a feed additive for improving the quality of animal meat or animal milk. The above object of the present invention is achieved by the following technical scheme: The invention claims the use of an odd-carbon saturated fatty acid selected from pentadecanoic acid and/or heptadecanoic acid, an odd-carbon saturated fatty acid ester selected from pentadecanoic acid ester and/or heptadecanoic acid ester and/or an odd-carbon saturated fatty acid salt selected from pentadecanoic acid salt and/or heptadecanoic acid salt for improving animal meat quality. The inventor finds that the odd-carbon saturated fatty acid, the odd-carbon saturated fatty acid ester and/or the odd-carbon saturated fatty acid salt can improve animal meat quality from various aspects and has the effect of obviously improving animal meat quality. Specifically, the improvement of the meat quality of the animals means one or more of improving the pH value of the meat, improving the meat color score of the animals, improving the marbling score of the animal meat, and reducing the drip loss or shearing force of the meat quality of the animals.
