Abstract:

A biological study was conducted to determine the effects of dietary supplementation of different levels of rare earth elements (lanthanum and cerium) on intestinal microbial count, ileal digestibility in post peak laying hens. A total of 96 White Leghorn laying hens of 52 weeks of age were used in 8 week feeding trial. Birds were randomly allotted to three dietary treatments each with four replicates and 8 hens per replicate. Treatments consist of basal diet supplemented with 0, 250mg (lanthanum 100mg and cerium 150 mg) and 500mg/kg (lanthanum 200mg and cerium 300 mg) of rare earth elements. At the end of 60th week, six birds per treatment were randomly selected and sacrificed. Intestinal contents were collected in sterile vials for intestinal microbial count, ileal digestibility and stored in airtight containers at -4°C. The results of this study showed that supplementation of rare earth elements (lanthanum and cerium) did not change the mean intestinal microbial count (log10 cfu/g) among the treatment groups. The ileal nutrient digestibility (%) of crude protein, crude fibre and ether extract of post peak layers showed 1-2 per cent improvement among the treatment groups over the control.
