Method used

By table 3 test result analysis, it can be known that wheat diet group is compared with corn diet group, pork fatty acid composition has no significant difference (P>0.05), illustrates that using wheat all replaces corn, can not cause pork fatty acid composition influences. After different levels of puffed flaxseed were added to the wheat diet treatment group, the fatty acid composition of pig pork among the treatment groups showed significant differences (P<0.05). The content of hexaenoic acid was significantly higher than that of the control group, and it increased significantly with the increase of the added level of expanded flax (P<0.05). The content of ω-3 polyunsaturated fatty acids in pork in the test group added with expanded flaxseed was significantly higher than that in the control group, and the ratio of ω-3/ω-6 was significantly reduced from 11:1 to below 3:1. Illustrate that the pig feed of the present invention mainly uses wheat as the energy source of the feed, and adds expanded linseed as the main source of ω-3 polyunsaturated fatty acids in the feed. When the price of wheat has an advantage, it can not only significantly red...

The invention relates to a wheat type fattening pig feed capable of reducing the ratio of omega-6/omega-3 polyunsaturated fatty acids in pork and application thereof, and the feed comprises the following components in parts by weight: 50-65 parts of wheat, 10-15 parts of rice bran, 8-12 parts of wheat bran, 4-8 parts of puffed flaxseeds, 8-12 parts of corn germ meal, 0.3-0.5 part of sodium chloride, 0.4-1.2 parts of calcium hydrophosphate, 0.4-1.5 parts of stone powder, 0.3-1 part of L-lysine hydrochloride and 0.1-0.2 part of choline chloride. The feed is prepared from the following raw materials in parts by weight: 0.03-0.05 part of a compound antioxidant, 0.03-0.05 part of compound non-starch polysaccharide enzyme, 0.2-0.4 part of a microelement additive and 0.2-0.4 part of a compound vitamin additive. The feed takes wheat as a main energy source, so that the cost is saved; by using the composite non-starch polysaccharide enzyme, the digestion and utilization rate of the pigs on the wheat is effectively improved. Compared with the prior art, the feed has the advantages that the ratio of omega-6/omega-3 polyunsaturated fatty acids in pork can be reduced, the absorption and utilization rate of wheat daily ration can be improved, and the production performance can be improved; and the preparation method is simple and low in production cost.

Example Embodiment

[0033] Example 1:
[0034] In this example, the 103-day-old Du × length × large three yuan mixed pig 180 heads (all half of the publicut), randomly divided into five groups, randomly divided into five groups, respectively For the control group, the treatment group 1, the treatment group 2, the processing group 3, the processing group 4, the five sets of corresponding feeding feed components and feed nutrition levels are shown in Table 1. 6 repetitions per group, each repeating 6 piglets, pre-feeding period 7 days, test period 50D. Test pigs transferred into the growth and fattening pig house by special person feeding management, during the period of regular epidemic prevention; after pre-provision, the morning is weighed, and the pig is free to feed, drink water, and the rest according to the routine management of the pig farm. Raise. At the end of the test, each group was weighed in units of each column, calculated the average daily weight loss (ADG) of each group of pigs; at the end of the test, the pigs only consummed only the amount of pigs, calculating average daily feeding capacity (ADFI) ) And meat ratio (f: g). After the test, a pig was randomly selected for a slaughter test, and the sampling fixed to remove the left half of the carcass back to the longest muscle sample 200g, -20 ° C. The muscle fatty acid composition was analyzed by gas chromatography.
