Abstract
This study was conducted to examined the effect of dietary supplementation of yellow loess on the growth performance and blood component profiles in pigs. A total of one hundred fifty three pigs (60 one weeks old piglets and 93 adult pigs). Piglets were randomly divided into 3 groups which were control, control + 0.5% yellow loess, control + 1% yellow loess. We measured body weight and weight gain among treatment group. Indeed, we obtained hematological data with WBC, RBC, Hb, Hct, MCV, MCH, MCHC, RDW, and PLT in all loess supplemented group compared to the control. Adults were divided into 2 group (control and control + 1% yellow loess) and serum albumin levels in 1% yellow loess supplemented group was significantly higher than the control group (p<0.01). Amount of crude fat in feces was significantly reduced in yellow loess supplemented group (p<0.001), but no differences were observed at crude protein and crude ash in both groups. In carcass weight and back fat thickness, no significant differences were observed between control and yellow loess supplemented groups. The carcass grade was improved by the dietary supplementation of yellow loess compared to the pig fed control. As a results, dietary yellow loess improves nutrient absorption and carcass grade.
