Abstract
This study was conducted to investigate the effect of probiotic from pine needle microbes on growth performance, blood characteristics, carcass traits and economy of pigs. One hundred eighty pigs (L${\times}$Y${\times}$D, average body weight=75 kg) were grouped and housed with 15 animals per pen for 3 replications per each treatment. The ingredients and pine needle microbes mixed and fermented on anaerobic condition for 10 days to make the fermented diet. The basal diet was substituted with 0 (CON), 3 (T1), 5 (T2) and 10% (T3) of fermented diet, the pigs were fed for 42 days and slaughtered at the end of the trial to measure the carcass traits. Crude protein concentration of fermented diet on 10 day was higher (p<0.05) than that of on 0 day, while crude fiber concentration and pH were lower (p<0.05). The supplementation of fermented diet did not affect on growth performance and feed intake. Hemoglobin concentration of whole blood in T3 was higher (p<0.05) than that of CON, and hematocrit concentrations in CON and T1 were higher (p<0.05) than that of T2 and T3. The concentration of platelet was higher (p<0.05) in T1 than in T2 and T3. The CON had higher (p<0.05) total cholesterol, LDL-cholesterol and triglycerides concentrations than the treatments, whereas lower (p<0.05) HDL-cholesterol concentration. Carcass weight and dressing in T1 and T3 were higher (p<0.05) than those of CON and T2. The backfat thickness was higher (p<0.05) in CON and T2 than in T3. The carcass grade and economy improved by supplementation of fermented diet compare to CON. In conclusion, the supplementation of fermented diet using probiotics from pine needle microbes could improve health and meat quality and reduce the feed cost of pigs.
