Impact of the inclusion of calcium soap in feed on intestinal histology and blood lipid profile of native chickens

The aim of this study was to examine the impact of the inclusion of calcium soap in feed on the intestinal histology and blood lipid profile of native chickens. This study used 192 native chickens aged 6 weeks with homogeneous body weight which were randomized into 4 types of treatment and 6 replications and each replication used 48 chickens with homogeneous body weight. The four types of treatment were: Group of chickens fed without the addition of Ca-PFAD as a control (chicken Group A); chicken feed with the addition of 2% Ca-PFAD (chicken Group B); chicken feed with the addition of 4% Ca-PFAD (chicken Group C); and chicken feed with the addition of 6% Ca-PFAD (chicken Group D). The results showed that the height of the jejunal villi in chicken groups C and D was significantly (P<0.05) higher than the control (chicken group A).  Likewise, the depth of the jejunum crypts of Group C and D chickens was significantly (P<0.05) deeper than that of Group A chickens.  The inclusion of 2-6% Ca-PFAD in the feed significantly (P<0.05) improved the blood lipid profile of native chickens.  It was concluded that administration of calcium soap (Ca-PFAD) in feed can increase the height of the villi and the depth of the crypts of the intestinal jejunum.  On the other hand, at the 4% level, giving calcium soap in feed can reduce cholesterol and Low Density Lipoprotein (LDL) levels, as well as increase triglyceride and High Density Lipoprotein (HDL) levels in native chicken.
