Abstract
In geese, overfeeding induces hepatic steatosis and makes the liver functions enhanced. Aluminosilicate absorbs toxins created by moulds in animal feeds and enhances nutrient absorption. In the present study, the effects of hydrated sodium calcium aluminosilicate (Improved HSCAS, Jumpstar) on the growth performance, fatty liver, serum parameters, and intestinal morphology of overfed Landes geese were evaluated. The study included two Control groups, a non-overfed Control (Control I) and an overfed Control (Control II), as well as a treatment group. The results showed that compared with the Control I group, liver weight, relative liver weight, abdominal fat weight, intestinal fat weight, villus height, total cholesterol, very low density lipoproteins, lipoprotein lipase, aspartate aminotransferase, IgM, and IgG in the HSCAS treatment group all significantly increased (P < 0.05) at Days 10 and 20. The villus height/crypt depth, triglycerides, cholinesterase, alanine aminotransferase, and serum IgA levels were higher than those in the Control I (P < 0.05) after 20 days of overfeeding. Compared with the Control II group, the relative abdominal fat weight, relative intestinal fat weight, and crypt depth in the HSCAS treatment group were significantly increased (P < 0.05) after 10 days of overfeeding, whereas villus height/crypt depth decreased (P < 0.05). Relative liver weight and IgA were higher in HACAS group after 20 days’ overfeeding (P < 0.05). HSCAS treatment also led to higher cholinesterase, very low density lipoproteins and decreased lipase, alanine aminotransferase (P > 0.05), and decreased aspartate aminotransferase levels than those in the Control II group (P < 0.05). In conclusion, HSCAS treatment had a beneficial effect on fatty liver production, intestinal development, and serum parameters in overfed Landes geese, which could enhance the health status of these geese.
