1. Materials and methods
1.1 Selection and experimental design of test piglets
The same batch was weaned, and the weaned piglets weighing 5-9 kg were 5 litters. The single-column double-slot feeding test method was adopted. After weaning, the two treated test materials were mixed for 1:1 mixing and then subjected to the splitting and splitting test. Two troughs were placed in each column, and each column was fed with the same quality 1:1 mixed feed per tank per day. After three days, the two tanks in each column are fed with the same quality of the original feed and the feed added with the oyster fermented material, and the corresponding mark is made on the trough. The position of the two troughs is changed every morning and afternoon at a fixed time. Remember to mark the feeding sequence for a total of 5 days of feed intake comparison test.
1.2 Test start time and location
The trial was conducted on the Shaoguan pig farm from 2015-02-06 to 2015-02 - 17.
1.3 Feeding Management
Refer to the company's current farm management system.
2, measurement indicators and methods
2.1 Observation of feed intake
Total feed intake per piglet per tank: = total feed per day - single treatment waste amount - single treatment daily feed residue
Daily partial eclipse rate of single- piglets per tank = (total feed intake per single day of treatment / total feed intake of piglets in full-column test) *100%
Then find the 5-day average
2.2 Data processing Use Excle calculation to compare relative feed intake.
3, the results of
3.1 In the case of adding 10% Shenyang Boshan fermented material, the partial eclipse test group was 58.27%. The control group was 41.73%, and the test group 16.54% more than the control group.
3.2 The test of the pig farm owner after the test said that after adding the company's products, the piglet skin is obviously rosy.
3.3 From the field observation, the diarrhea rate of the participating pigs (control pigs and test pigs) was 10-15% lower than that of non-test pigs.
