example 1

[0022] 40 healthy and disease-free Japanese Wagyu hybrid bulls weighing 462±11.7kg were randomly divided into two groups, the control group and the experimental group, and the experimental site was Wudi Beef Cattle Farm.

[0023] The beef cattle feed of the test group consisted of the following raw materials by weight: 40 parts of forage, 28 parts of corn, 8 parts of wheat, 8 parts of cotton meal, 1 part of salt, 5 parts of additives, 1 part of Schizochytrium powder, 2 parts of sunflower seeds, Apple pomace powder 6.9 parts, bile acid 0.1 part. The beef cattle feed of the control group consisted of the following raw materials by weight: 40 parts of forage, 32 parts of corn, 12 parts of wheat, 10 parts of cotton meal, 1 part of salt, and 5 parts of additives.

[0024] The pre-test period of the experiment was 10 days, and the main test period of the experiment was 120 days. During the experiment, the feed intake, daily weight gain, and feed remuneration were recorded. After th...

[0030] 40 healthy and disease-free Simmental hybrid bulls with a weight of 462±11.7kg were randomly divided into two groups, the control group and the experimental group, and the experimental site was Yangxin Beef Cattle Farm.

[0031] The beef cattle feed in the test group consisted of the following raw materials by weight: 40 parts of forage, 28 parts of corn, 8 parts of wheat, 8 parts of cotton meal, 1 part of salt, 5 parts of additives, 1 part of Schizochytrium powder, 3 parts of sunflower seeds, Apple pomace powder 5.9 parts, bile acid 0.1 part. The beef cattle feed of the control group consisted of the following raw materials by weight: 40 parts of forage, 32 parts of corn, 12 parts of wheat, 10 parts of cotton meal, 1 part of salt, and 5 parts of additives.

[0038] Proportions (parts by weight): 40 parts of forage, 28 parts of corn, 8 parts of wheat, 8 parts of cotton meal, 1 part of salt, 5 parts of additives, 1 part of Schizochytrium powder, 1 part of sunflower seed, 7.9 parts of apple pomace powder, 0.1 part of bile acid.

[0039] The method of obtaining apple pomace powder is as follows: blow dry fresh apple pomace at a temperature of 50-70°C for 8-10 hours, and stir once every 30 minutes during this period to prevent browning of the apple pomace powder. After the product is crushed, pass through an 80-mesh sieve to obtain apple pomace powder.

[0040] The total bile acid content of bile acids is ≥90%.

Abstract

The invention discloses a feed capable of increasing the content of polyunsaturated fatty acid in beef. Schizochytrium limacinum powder, sunflower seed, apple pomace powder and bile acid are added to raw materials of a frequently-used feed for beef cattle, are combined and compounded to form a mixed diet, wherein the mass ratio of the schizochytrium limacinum powder to the sunflower seed, the apple pomace powder and the bile acid is 0.8-1.2:1-3:5-8:0.08-0.12, and the total weight of the schizochytrium limacinum powder, the sunflower seed, the apple pomace and the bile acid accounts for 8-12% of the total quantity of the feed. According to the feed disclosed by the invention, selected materials are excellent, economical and practical; after the beef cattle eat the feed which is weighed according to an appropriate compounding ratio, the content of unsaturated fat acid in fat tissues of meat products can be effectively increased, and particularly the content of CLA and the content of DHA are increased. Not only can the food flavor be improved, but also the cholesterol content in beef is reduced, so that the nutritional level of the meat products is greatly increased.

Description

technical field [0001] The invention belongs to the field of feed, and in particular relates to a feed for increasing the content of polyunsaturated fatty acids in beef, especially CLA (c9, t11-CLA) and DHA. Background technique [0002] Fat is composed of saturated fatty acids and unsaturated fatty acids. Unsaturated fatty acids are further divided into monounsaturated fatty acids and polyunsaturated fatty acids. Polyunsaturated fatty acids mainly include linoleic acid, linolenic acid, and arachidonic acid. Polyunsaturated fatty acids are important essential fatty acids for humans and must be supplemented from the diet. Various vegetable oils are important sources of polyunsaturated fatty acids. [0003] Among polyunsaturated fatty acids, conjugated linoleic acid (CLA) is an isomer of linoleic acid, and CLA is divided into c9, t11-CLA and t10, c12-CLA. A large number of studies have shown that CLA can scavenge free radicals, enhance the body's antioxidant capacity and imm...
