Wheat type fattening pig feed capable of reducing ratio of omega-6/omega-3 polyunsaturated fatty acids in pork and application of wheat type fattening pig feed

[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.
