Appropriate amount of dried apple pomace in pig production

Yang Fuyou et al. To verify whether silage malic acid can replace citric acid as an acidifier in the diet of weaned piglets, 64 pigs aged 35-40 days old hybrid weaned pigs were divided into 4 groups, and the control group contained 1.5. % citric acid, 3 treatment groups of diet containing 2%, 4% and 6% silage dry apple pomace (pH between 3 ~ 4, containing lactic acid, citric acid, malic acid, acetic acid and other organic acids), 2 replicates in each group, 8 pigs per replicate, 45 days in the trial period. The results showed that the average daily gains of the 2%, 4%, and 6% dry apple pomace groups and the control group were 473 g, 470 g, 458 g, and 471 g, respectively, and the feed-to-weight ratios were 2.26, 2.27, 2.34, and 2.27, respectively. The difference of each group was not significant (P>0.05); the severe diarrhea rate of piglets was 4.8%, 4.2%, 3.8%, 3.9%, the difference was not significant (P>0.05). It can be seen that there is no difference between the effect of feeding the weaned piglets with suitable horizontal silage and the 1.5% citric acid feeding effect. The optimum dosage of silage dry apple pomace is 4%. iDc China Feed Industry Information Network - based on feed, serving animal husbandry
