Growth performance, carcass traits and histological changes in the intestinal villi of male broiler chickens fed dietary silicic acid powder containing bamboo vinegar liquid
Journal Title: Journal of Animal and Feed Sciences - Year 2015, Vol 24, Issue 1
Abstract
To evaluate the effects of silicic acid powder containing bamboo vinegar liquid (SPV) on growth performance, carcass traits and intestinal histology, 80 male broilers at 7 days of age were divided into four treatment groups, each with four replicates of five chickens. The birds were fed ad libitum a basal diet supplemented with SPV at a level of 0%, 0.1%, 0.2% or 0.3% until 49 days of age. Body weight gain was the highest in chickens fed the 0.2% SPV diet. The dietary treatments had no significant effects on performance or carcass traits. Tissue observations by light microscopy revealed that villus height and villus areas of the duodenum and jejunum were comparatively higher in the 0.2% SPV group. Duodenal and jejunal cell mitosis were also increased by this diet. These results indicate that dietary SPV at 0.2% could stimulate intestinal functions in broiler chickens.

Raw vs extruded coloured-flower pea as an ingredient in broiler diets: effects on performance, ileal digestibility, gut morphology, and intestinal microbiota activity
T: Raw or extruded peas (Pisum sativum, pink-flowered cv. Milwa) were used. Extrusion reduced the trypsin inhibitor activity (TIA) from 2.35 to 0.35 mg · g–1, but did not affect tannins content, which was about 1 g · kg–...
